@tidal kiln I want to know how a dictionary would work with this function
#circuitpython-dev
idle owl
tidal kiln
would need to see more of the code.
is what's in the current repo pretty much it? and then what you showed earlier?
tulip sleet
@idle owl @tidal kiln what would you folks think of returning actual board.A2 (the Pin object) rather than "A2" or "2"? Maybe too confusing?
idle owl
Yes, exactly. The express.py I'm working from at the moment is stripped down so I can edit it live and not get memory issues, but otherwise it's what 's in the repo
@tulip sleet I think it would be confusing yes
@tulip sleet I want to add iteration but maintain the code being what's labeled on the board
tidal kiln
@tulip sleet since you mention it. i'm curious - what actually is board.A2? (in terms of python type)
tulip sleet
@tidal kiln it's an instance of the Pin class. They're created in advance and available as constants from board.
>>> board.A2
board.A2
>>> type(board.A2)
<class 'Pin'>
I didn't even know that was an option. That's great
tulip sleet
board.A2 and board.D0 are the same pin on CPX. The CPX numbering is kind of all weird to preserve compatibility with CP classic. (EDIT: good example, but wrong board)
tidal kiln
oops. sorry for lack of context. that was on a Trinket.
tulip sleet
Trinket is also preserving numbering with original Trinket.
tidal kiln
hold on. let me get more in sync...
tidal kiln
ok. got that. i should familiarize myself with that class. assume it's in the api doc?
tulip sleet
tidal kiln
hmmm. so it just is what is. no methods or properties.
tulip sleet
Unfortunately they don't print all that interestingly, like with the pin name. Also the chip pin number is used a lot, so you see stuff like Pin PA12 in use, which doesn't tell you much.
idle owl
Scott told me to use gc mem free or something to that effect. I can't find anything on how to do it. gc doesn't have a "mem free" that I'm finding in the docs, but I'm obviously missing something. I think he told me 3 or so commands to type into the REPL, but I didn't get all, of them. How do I check the free memory from the REPL?
solar whale
Import gc then gc.mem_free()
tulip sleet
also micropython.mem_info()
tulip sleet
yeah, that's what I was thinking of. Maybe not great for the cpx library, but good for people who actually refer to board.xxx
idle owl
Agreed
formal plover
Awesome, great job @tulip sleet!
tidal kiln
yeah, and i think the cpx library should lean more towards a more user friendly interface
tulip sleet
it would be nice if Pin had some property that was the board label string. Not sure what we would need to do to make it work across multiple boards, but should be possible.
tulip sleet
Sounds like it should be a GitHub issue (it might be one already)
drowsy geyser
@tulip sleet labeled like how? We already have things that are descriptive, like board.SCL....
floral dagger
@idle owl this?import gc gc.collect() print(gc.mem_free())
tulip sleet
@tidal kiln @idle owl so anyway, I was kinda interrupting you about the dictionary stuff
idle owl
@floral dagger import gc gc.mem_free()
floral dagger
lol nm I see it was answered
tulip sleet
@drowsy geyser but if you have some anon Pin object, you can't find out what its original name is.
tidal kiln
no worries. glad you mentioned it. relates to something i was thinking about some days ago.
idle owl
@tulip sleet No it's fine! I'm learning more and better to have more ideas
drowsy geyser
Oh oh oh, I'm being dumb. Yes, you're right!
tidal kiln
@tulip sleet you've read through the related issue?
https://github.com/adafruit/Adafruit_CircuitPython_CircuitPlayground/issues/12
idle owl
@tulip sleet I have working code now, but @tidal kiln was suggesting another way to do that I had considered while working on it but it wouldn't have worked with my original idea.
tulip sleet
@drowsy geyser no dumb!
@idle owl I did look at your code. I wish DigitalInOut had a .pin property so you could just get the pin back. But it doesn't.
idle owl
@tulip sleet Ah yeah
tulip sleet
@tidal kiln so i assume you were thinking of creating a dict to map the DigitalInOut objects to pin names or numbers.
tidal kiln
maybe. something like that.
first, curious which of the usage syntax's you think looks best (int vs. string)?
tulip sleet
Since on most boards pin names don't match numbers all the time (e.g. your trinket example), a name is probably better. E.g. A1 is D10 on CPX, I think (or similar).
tidal kiln
my thinking is that A1 is printed right on the board, so the string based syntax might be more user friendly
tulip sleet
yes
tidal kiln
the umpteen different levels of pin abstraction are of little interest
idle owl
Side note, I'm also considering calling it cpx.touch - it would be more in line with the other touch code. That's irrelevant to what we're doing now though.
tidal kiln
worth thinking about though
and i'm not so good at that myself. i always go round in circles. touched no wait touch no wait are_touched no wait.....
tulip sleet
'A2' in cpx.touch ? Actually I kind of like touched since it indicates state. What's another API that's just touch?
idle owl
It's not just touch, they're touch_A1
etc
I think they both work "if you touch A1, it prints" "if A1 has been touched, print"
tulip sleet
touch_all?
tulip sleet
.touch_A1 returns a boolean, but touch returns a tuple of pin names
idle owl
But only one at a time, I think
tulip sleet
so it doesn't seem so parallel to me
idle owl
fair enough
tulip sleet
cpx.touch could return (False, True, False, False, ...) for all the pins, but that's actually not so great
tidal kiln
no. think of usage.
tulip sleet
it can be more than one at a time, right? cpx.touched -> ('A1, 'A3')
idle owl
Ah
floral dagger
so, returning a reference to the pads touched rather than a set of true/false responses for each pad?
tidal kiln
correct. i think the only question is what exactly the reference should be.
tulip sleet
@idle owl come to any conclusion?
idle owl
Not exactly. Both options make sense. We can stick with touched.
I'd say wait for Scott's opinion but most of the time he tells me to decide 😃
floral dagger
is there an equivelant function for other parts of the board?
tidal kiln
use klingon then!
tidal kiln
digital in pins?
tulip sleet
he is good at having people move forward into new territory😀
floral dagger
Is there a function to return what neopixels are lighted for example? If so, should they be consistent?
idle owl
@floral dagger I would call it pixels.lit or something, but no there's not eqivalent functions for other parts of the board. All of the tone stuff has "tone" in it, so it's kept uniform when there are multiples...
floral dagger
ah, ok...thanks @idle owl
tidal kiln
if 'D1' in cpx.low_pins:
print("D1 is LOW!")
We've not yet written up two different ways to do similar things for any of the other APIs
Haven't needed to
This is the difference between each invidivual pin, or returning info from a tuple of all of them
It's not a difference in state of the pins between this and the other part of the API
tulip sleet
The touch stuff is input. The pixel values are known to the programmer. If we were attaching buttons to a bunch of pins something like cpx.low_pins might be helpful, but there isn't a central place where the DigitalInOut pins that are set to input are known.
unlike the touch stuff
floral dagger
Say pixel.lit returns a list of variables that references the pixels in a certain way, it would seem intuitive froma user standpoint that "touch" or any other equivelant should behave similarly.
But if that's not there, then it doesn't matter anyway 😃
idle owl
Heh, yeah. This is the first time we've done something like this, other than there being multiple versions of *_tone
floral dagger
You all know way more than I do, so I'm probably not much help. Just trying to learn
idle owl
@floral dagger I am still pretty new to all of this. Seriously. I'm learning so much as I go as well. You're a very welcome part of this conversation!
Anyway, debating design doesn't require huge amounts of knowledge. In the end, design is a matter of how it looks to a user. Having different perspectives on this is always good.
drowsy geyser
@tulip sleet is a wizard. Where do we send alms? 😃 [CP for the M4 is now compiling after he showed me how to update the gcc toolchain!]
tidal kiln
@drowsy geyser #hug-reports
tulip sleet
@drowsy geyser Don't worry - Adafruit sends me alms already.
drowsy geyser
Me too! After all, I have an M4 to work on!
tulip sleet
I am fading. I'll say goodnight!
drowsy geyser
G'night!
idle owl
@tulip sleet Good night! Thanks for all your input!
@tidal kiln I guess the most important thing here is, does this do what you wanted? I mean, your code examples work, but that's not necessarily the same thing.
tidal kiln
you're giving me too much sway. i think the idea of a tuple return is useful. but details are a point of design and discussion.
didn't mean for you to think both had to be implemented.
idle owl
I learned a ton from figuring all that out. Totally worth it.
Anyway Dan asked for the same thing when I was writing the original API but we decided it might be an edge case. So you asked wasn't new, but it meant we were wrong.
Which is good!
I'm just making sure that the functionality you were looking for is there. Design can be sorted, but that part I want to make sure is solid.
tidal kiln
so, looking in the PEP20 zen refamadoodle:
"There should be one-- and preferably only one --obvious way to do it."
idle owl
lol
tidal kiln
so even more sorry you did both
idle owl
I'm serious that it was worth it. Promise.
tidal kiln
what do you think about the string version?
idle owl
I like it returning what's labeled on the board. That part I'm steadfast with, have been this entire time because in teaching a friend how to use this board, trying to explain everything starting with 0 and so on was a new concept to them, so having it be already on the board is super useful.
tidal kiln
i agree
idle owl
Whether it's touch or touched isn't really a big deal. I'll probably ask a few other people which makes more sense on it's face and give that consideration to figuring that out.
tidal kiln
thats sounds like a very good idea
idle owl
I don't understand tuples well enough to know if the core functionality of the function does what you (and Dan) were looking for. That's why I asked. Going based on your random code suggestions, I nailed it, but I don't know how to test it beyond those examples, so I have no way to extrapolate the potential use cases.
tidal kiln
are you still confused about tuple vs. list?
idle owl
Nope, that part makes sense
It's just not understanding what another example might look like. Or what I might use it for in general.
tidal kiln
tuples?
idle owl
The entire function I mean, not a tuple specifically
What another example of code that works with this function might look like
tidal kiln
oh
idle owl
I need to be more clear here lol
tidal kiln
other than the ones in the issue?
idle owl
Yep
I have no idea how to use the function I made beyond changing the numbers in what you posted in the issue.
Why would I use it?
What is another example of it?
That's what I mean
Or did your issue cover all the potential code that works with it
tidal kiln
not at all
idle owl
I have this right now while True: if 'A1' in cpx.touched(): print("touched A1") for pad in cpx.touched(): print("pad {0} touched!".format(pad))
tidal kiln
it's general purpose
idle owl
I wouldn't know what else to try
I know it prints for A1 twice, I was just making sure they both worked 😃
tidal kiln
not a really good example, but imagine what the last two lines would look like using the current api
idle owl
Ah ok yeah
tidal kiln
for the if one, imagine if the A1 were something more variable
idle owl
How would that work? I tried a few things but it just stopped working completely
umbral dagger
My 2 cents on pin instances vs strings... You loose any richer information by going to strings. I always look twice when I see strings being used to represent things. When you have a string, that's all you have.
tidal kiln
MAKE_ROCKET_GO_PIN = board.A1
#
# thousands of lines of code
#
if MAKE_ROCKET_GO_PIN in cpx.touched:
make_rocket_go()
@umbral dagger It's meant to be simple.
umbral dagger
Another 2 cents... in a constrained environment, sometimes simpler (and smaller) is better.
tidal kiln
then you decide you want A2 instead
idle owl
And you're not searching thousands of lines of code....
umbral dagger
@idle owl And it's not as if Python is going to do a lot of type checking, so you don't get that benefit by having somethign more specific.
idle owl
@umbral dagger Exactly. And all the CircuitPython stuff will still work. This is meant to be a simpler class that allows you to learn how to program and work your way to the core stuff.
umbral dagger
That's where I think the M4 will be a game changer... the expanded RAM space.
idle owl
Also exactly
umbral dagger
@idle owl Ya.. I only have partial context on this.
idle owl
@tidal kiln Alright, that makes more sense.
tidal kiln
not only searching the lines of code, but with the current api you'd have to change the actual function call, cpx.touched_A1 to cpx.touched_A2
floral dagger
@tidal kiln I was thinking of a sort of "combination" lock where you had to touch all the correct pads at the same time.
tidal kiln
that's a good one too. having a tuple to work with would make that simpler.
idle owl
otherwise it's if cpx.touched_A1 and cpx.touched_A2 and etc.
How does it look with the tuple code
tidal kiln
and if you change the combo?
with a tuple, you use in, but to check for multiple, there's some pythony trick
here's what the google says:
https://stackoverflow.com/questions/6159313/can-python-test-the-membership-of-multiple-values-in-a-list
hmm, but that's a list
should work for tuple too
idle owl
Ah
tidal kiln
>>> COMBO = (1,2,3)
>>> all(x in (1,2,3,4,5,6,7) for x in COMBO)
True
>>> all(x in (3,4,5,6,7) for x in COMBO)
False
>>>
yep
idle owl
nice!
tidal kiln
COMBO = ('A1', 'A2', 'A5')
if all(pad in cpx.touched for pad in COMBO):
print("UNLOCKED!")
else:
phone.dial(911)
good example @floral dagger !
umbral dagger
@idle owl Very nice
idle owl
@tidal kiln Needed (): if all(pad in cpx.touched() for pad in COMBO): But now it works! I remembered from earlier that I had forgotten () and it gave me a bound_method not iterable error. Can't believe I remembered that enough to figure it out immediately.
tidal kiln
did you @ property it?
idle owl
I didn't figure it out myself the first time, lol. I had help. But I remembered!
I did not
and now that you mention it, I remember that it resolves needing the ()
Or the () showing up on Sphinx docs, lol
tidal kiln
easy to crack though. just touch all pads.
idle owl
I feel like if someone malicious has access to your CPX, them cracking the code to print unlocked is the least of your worries.
slender iron
lets talk about this touched business tomorrow during our voice chat! its an awesome discussion
idle owl
Will do 😃
tidal kiln
glad we answered your question about using a dictionary!
idle owl
Now I have to come up with something else to learn dictionaries!
@tidal kiln Thank you so much for all your time. I really appreciate it!
glacial bronze
It might be that dictionaries might be a good way to define pins (with another layer of abstraction). You could make a given MCU's pindefs more easily portable to other boards with the same MCU by having a dictionary of pin numbers to MCU pins
idle owl
And now it's time for me to call it. Thank you @floral dagger and @umbral dagger for your input!
tidal kiln
try writing a program that prints different things with different touched pins
and store those responses in a dictionary
umbral dagger
@idle owl Any time
tidal kiln
or to map a set of neopixels to light to a touch pad
floral dagger
yw @idle owl Gn. It always fascinates me to watch all this stuff come together.
I've been working with the MQTT stuff over the weekend. It works pretty well on CP connecting to Adafruit IO. It's an interesting protocol. Have any of you worked with it in CP yet?
umbral dagger
@floral dagger Not in CP yet. In C, Go, and Scheme, though.
tidal kiln
# a dictionary of tones
tones = {
'A1' : 262,
'A2' : 294,
'A3' : 330,
'A4' : 349,
'A5' : 392,
'A6' : 440,
'A7' : 494,
}
# get all currently touched pads
touched = cpx.touched
# if there are some
if len(touched) > 0:
# play the tone associated with the first one
cpx.start_tone(tones[touched[0]])
@floral dagger Actually twice in Scheme, where I build integrations with the underlying Go and C libraries.
@floral dagger It's a nice protocol. Simple, yet functional.
floral dagger
nice @umbral dagger I was surprised how little info there is for a beginner, but once you start piecing it together it does come together nicely.
umbral dagger
@floral dagger There's a fair bit of information on the paho site: https://www.eclipse.org/paho/
floral dagger
@umbral dagger IThanks! I'll have a look at that. It's funny, I have like three or four sites I was going through. One has a great graph of the bit order for connections, one explains what it does. It's all very fragmented between all the different software that implements it
umbral dagger
@floral dagger Oh.. and they have a fairly clean looking python implementation
umbral dagger
@floral dagger I'm using the paho C implementation as the basis of my current ChickenScheme support
floral dagger
Yeah, the micropython one is fairly complete.....but they've not implemented non blocking connections
it has the function, but just calls the one forblocking inside of it, which is odd
oh cool @umbral dagger
umbral dagger
Ah sweet! My first CP PR!
@slender iron So... did you swap out the flash on a Feather to test the PR? 😉
Happy hacking, west coast folks. bedtime here for me. M4 arrives tomorrow.. I am excite!
slender iron
@umbral dagger nope, it won't be "officially" supported. Good night!
Hi everyone and <@&356864093652516868>, our weekly is on for tomorrow (Monday) at 11am PT / 2pm ET in this text channel and the CircuitPython voice channel. It'll be the usual Hug Reports, State of CircuitPython, Status Updates and Odds and Ends as usual. See you there!
@hollow tartan the first step is getting your own ESP8266 build going
hollow tartan
I have a github acct
slender iron
there are instructions here to do it using a vagrant VM: https://learn.adafruit.com/building-and-running-micropython-on-the-esp8266/build-firmware
what os are you on?
hollow tartan
win 7
slender iron
kk, vagrant is a good approach then. I believe @solar whale has ESP8266 builds going that way as well
hollow tartan
Oh Kay 😃
slender iron
once you can load your own build, you can confirm that the code doesn't work like it should (see the bug) and then fix it 😃
slender iron
lots of folks here to help 😃
hollow tartan
Alright, I have my marching orders. Thank you, sir.
slender iron
no problem!

@slender iron I can now successfuly build a .uf2 version of CP master and load it to the metro_m4 via your new bootloader. I wish I could explain what is different, but I may have just been loading the wrong file before. In any case - it seems to be working fine now. At least this time. I tried reloading the firmware.uf2 file you provided and have mixed results with it as I did last night. Sometimes it hangs in REPL then eventually unmounts CIRCUITPY. My latest debug build is: Adafruit CircuitPython 3.0.0-alpha.0-29-g1c97b7f4d on 2017-10-23; Metro M4 Express with samd51j19 -- current master.

@slender iron one more update on using the UF2 bootlaoder- I can only get the new UF2 bootlder to be regognized on my MACOS system. My linux system and my Raspberry Pi do not mount the METROM4BOOT file system when I doubletap. They will sometimes mount the CIRCUITPY system but sometimes won't mount it unless I reboot them. It will mount CIRCUITPY after a reboot of the linux box. It all works fine on the MACOS box....the linux box and raspberry pi still report lots of errors ```Oct 23 06:01:27 Ubuntu-Macmini kernel: [ 322.125651] sd 7:0:0:1: [sdd] Unit Not Ready

@slender iron since my work from home day got moved, I won't be able to participate in today's meeting. Womp womp 😿

@slender iron I should be able to attend the meeting today.
tulip sleet
@solar whale I had an extended episode over the weekend in which no M0 boards (Including CPy 2.x) would appear as ...BOOT on my Ubuntu 16.04 Linux box. I rebooted with an older kernel to no avail. I then powered down completely and things were better. I don't like not understanding why this is happening.
umbral dagger
@tulip sleet UBS ports can get locked out sometimes (especially if too much current gets drawn, but I’ve seen it happen for reasons that aren’t clear). Check if the port works with something else. Often a reboot seems to be required to reset things.
My M4 will be well travelled by the time it gets here.
tulip sleet
@umbral dagger The port was still working: I could mount CIRCUITPY manually, but the automount was not working. However, it may have been in some kind of bad state. When I looked at dmesg, it seemed to be complaining about the filesystem. However, no USB drive (not just M0 boards) would work at all. I have a number of USB sticks that didn't show up. So I was looking for any recent Linux changes that might have affected this.
those M4 travels are indeed ridiculous: "I need to get to Canada tomorrow. Well, sir, we can route you through Iowa and then Montana and then back to Toronto. How's that."
umbral dagger
@tulip sleet ugh. USB can get weird. I imagine the file system stuff adds another layer of potential weirdness.
I can understand odd routing to take advantage of space in planes for overall faster delivery, but the loops ...
formal plover
My M4 is in Phil's inbox. Lol
Haven't had the heart to tell him he overlooked my email yet.
I haven't had a lot of time to test anyways.
tidal kiln
@formal plover can mention today
formal plover
@tidal kiln yeah, I might just DM Scott what I would say in today's weekly. I won't be able to participate today unfortunately.
tidal kiln
ok. and then you can also mention the M4.
umbral dagger
M4 is finally on the truck and out for delivery!
solar whale
@tulip sleet do you see any messages like the ones I posted in via dmesg?
tulip sleet
@solar whale I am seeing those. I am also seeing this odd behavior: connect CPy 2.x Gemma or Trinket. REPL works fine. Connect up 3.0 CPX. Use REPL a little. Unplug it. Now no board (including 2.x Gemma and Trinket) work with repl. I get "screen is terminating" messages. However, it does appear to work with "sudo screen". If I look at the protections on /dev/ttyACM0, they are wrong. Then it flips back, at random, after unplugging and replugging, but only sometimes:
crw------- 1 root root 166, 0 Oct 23 11:27 /dev/ttyACM0
halbert@salmonx:~$ ls -l /dev/ttyACM0
crw-rw---- 1 root adm 166, 0 Oct 23 11:28 /dev/ttyACM0
It's as if unplugging the 3.0 CPX leaves the linux kernel or drivers in a bad state.
this wrong protection is also coincident with CIRCUITPY and ...BOOT drives not showing up.
tidal kiln
i've seen something that may be related. sometimes the drives get mounted as read only. (on linux)
tulip sleet
sometimes they are read-only if the driver thinks they are damaged (same old delayed-write problem); but could also be protecttion?? There are recently created systemd-udevd processors in ps. I have looked at recent changes in systemd, but haven't found anything suspicious.
it's like the udev rules aren't working all the time
tidal kiln
yep
tulip sleet
I do have the Adafruit-supplied udev rules to allow non-root access to ttyACM0
tidal kiln
same here
tulip sleet
@tidal kiln you mean same permission problem?
tulip sleet
yep, they have worked fine up to now. Either something changed in how they are treated or something bad is happening sometimes when device is plugged in (or previous device is unplugged)
tidal kiln
yeah, it seems related to plugging/unplugging
solar whale
I have had them mount seemingly read only when I try to drag/drop but I can cd to the directory in a terminal window and write to it.
tidal kiln
when it's happened on one machine, i've simply moved to another (also linux, also has udev rules) and it all works fine
@solar whale what're you on?
because now that you mention it, same for me
solar whale
Linux Ubuntu 16.04 also raspberry pi stretch.
tidal kiln
same here, ubuntu
solar whale
Works on macOS
tulip sleet
and same here, updated as of a few minutes ago with latest packages
tulip sleet
yeah it takes care of automatically mounting. But I don't see why it would have to do with the /dev/ttyACM0 permissions.
tidal kiln
could explain why it's interfering at the gui, but not at the cli
but yeah, doesn't explain your ls of /dev/ttyACM0
tulip sleet
When the filesystems don't show up, I see nothing in /media/halbert. But I can sometimes mount the filesystem by hand with sudo mount. However I also get complaints that it's damaged and won't mount. Fixed by reboot.
well, not sure about the reboot. it may be inconsistent
stuck elbow
@tulip sleet I get a similar permission problem with the usb drive
tidal kiln
also - i haven't done anything with 3.0 yet, so don't think there's any relation to that
stuck elbow
I just assumed it's ubuntu being stupid and broken
tidal kiln
i think it's that
stuck elbow
I have that with 2.x
tulip sleet
did any of your have the unable to connect to repl problems with 2.x recently (past few days)?
tidal kiln
yeah, me neither, at least not that i've noticed
tulip sleet
i think these may be separate problems
tidal kiln
i think so also
the auto mount to /media and the drag/drop are gui things
the permissions on /dev/ttyACM0 are something else
tulip sleet
or, the usb driver problems are affecting downstream things like the automount. not sure if ttyACM0 permissions are downstream or not. I have to read how it all works.
it's time for me to be methodical in testing
there's always a reason; it's not cosmic rays
tidal kiln
good luck. please report back.
split ocean
Hi all, do we have a preferred way to do random? I want something like 'random(1, 10)' for a value.
looks like MicroPython docs say: https://microbit-micropython.readthedocs.io/en/latest/random.html
tidal kiln
that's the random module, which then has what you're probably looking for
can you describe the use case more?
split ocean
@tidal kiln I'm doing some tone generation and want to have some randomness so it doesn't sound like a pattern.
tulip sleet
@solar whale when you can't connect, let me know if the permissions are wrong
solar whale
Ok will be home in a while
split ocean
something like: 'cpx.start_tone(288 + (i * (random(1, 10))))' where i is me looping through ten times.
tidal kiln
looks like maybe you want random.randint(1,10)
stuck elbow
@split ocean if you use the pentatonic scale only, it will sound good even if completely random
tidal kiln
you want to send start_tone() a value that ranges from 288 up to some random offset?
split ocean
thanks @tidal kiln that did the trick
yes, it's based there at 288 and then each iteration "wobbles" around a bit by that random value
I'm not saying it's aliens. But, it's aliens.
tidal kiln
can maybe replace whole thing with random.randint(288, 288+WHATEVER)
stuck elbow
aah, for alien stuff definitely you don't want pentatonic 😃
tidal kiln
to answer your original question - i don't think there's one 'preferred' way, other than just using what's available in the random module
and if you want truly random, you'll need to seed it
random.random() is the basic functionality, but don't overlook the other useful ones like random.choice()
and when using randint or randrange be careful about the inclusiveness of the range
split ocean
thanks much!
i don't need true randomness, just organic variance : )
i like the looks of random.choice() thanks, that could be fun to feed it only the notes I want for some other music-ish projects.
tidal kiln
yep
instead of generating a random index value and using that to retrieve the item out of the sequence
umbral dagger
The M4 arrived. Now to resist the temptaton and try to get some work done. You know.. for the people who pay my bills 😃 OK, so it's generally also fun.
solar whale
@tulip sleet Are you looking for permission issues with 2.1 connections or 3.0? THe only 2.1 issue I have seen is sometimes not automounting CIRCUITPY an then it appearing to be Read-only. With 3.1 it does not even create ttyACM0 some of the times.
tulip sleet
@solar whale I mean the root-only permissions on ttyACM0, not filesystem permissions. I haven't seen filesystem permission issues except with write-delay problems. What I do see is the filesystems not even mounting. And yeah, with /dev/ttyACM0, sometimes it's not even there.
floral dagger
@split ocean If you just want to sort of "warble" a tone around the central tone, you could probably do something like ((random.random()*.05)*tonevalue) + tonevalue It's similar to what I am using on a candle project to sort of randomize the blue LED by 0-5%of its base value

@tidal kiln @solar whale @tulip sleet USB problems in 3.0 wouldn't surprise me at all. I don't think the ASF4 Chapter 9 USB stack is very well tested.
split ocean
thanks @floral dagger I'll try that out
tulip sleet
@slender iron yeah, and it seems to be getting the Linux USB stack into a bad state in some way
slender iron
yeah, that doesn't surprise me. I have a linux box I can test with after I finish the UF2 stuff
solar whale
MacOS seems to be far more tolerant of it.
tulip sleet
if you can duplicate it, that would be great. You can look back for the issues, or I can give you a recipe: (unplug 3.0 board after REPLing, then try any other board)
Linux stack should be more robust than that
solar whale
It is almost alway OK immediately after reboot of the linux box, but it deteriorates quickly.....
I was concerned that it was relaled to use of Jlink, but I think the JLink USB connection is just caugt up in whatever is getting hosed.
drowsy geyser
@slender iron I just ordered a box to install Linux, so I should be able to help test/debug in about a week.
@solar whale Can you force the condition with other USB devices? (Sorry, I'm at work so missed the conversation.)
tulip sleet
@solar whale I haven't been using jlink at all during these problems -- it's not even plugged in.
drowsy geyser
Well there's the answer. Thanks, @tulip sleet
solar whale
I have not had issues with any other USB devices.
tulip sleet
@drowsy geyser it happens after using 3.0 boards. Then many things don't work, such as plugging in regular USB sticks: their filesystems don't show up. But only the 3.0 boards seem to provoke the problem.
off for a few mins
drowsy geyser
Oh, that's fascinating. Not good, but fascinating.
I'll see what I can do once I get my Linux system built.
solar whale
I think @slender iron is going to regret enabling so many early testers 😉
@tulip sleet I alos had issues with a metro_M0 3.0 build. Have you seen that as well. I can try that again if needed.
tulip sleet
I am seeing these issues on CPX 3.0 build. Haven’t even started on M4 yet.
solar whale
just loade 3.0 on M0 - USB drive did not auto mount and ttyACM0 looks OK and I can connect, but no response from REPL an dit exits after a few minutes
CIRCUITPY is not accessible.
slender iron
@solar whale nah, I'm ok having bugs found early
solar whale
Moved USB cable to MACOS and it mounts CIRCUITPY and REPL works fine
slender iron
@solar whale I have a bad habit of using infinite loops in error cases. You may be hitting one of them
solar whale
@slender iron what part of the code it this likely occuring in?
slender iron
not sure. I use the while loops because I can get a backtrace with a debugger
solar whale
I was just curious wher it may be useful to look at the code - where is most of the USB stuff you are working on?
BTW on M0 the REPL does not print out garbled strings like it does on the M4. import board then dir(board) looks normal on M0, but gets garbled on M4.
slender iron
ah! in atmel-samd/usb.c and atmel-asmd/usb_mass_storage.c
solar whale
thanks.
slender iron
no problem!
solar whale
now have a new wierd case - CP 2.0 on M0 all good on MacOS but on Ubuntu - CIRCUITPY is empty? REPL works OK. - went back to MacOS and CIRCUITPY has all its files in place!
and os.listdir() on the UBuntu system shows all the files, but they are not visible on CIRCUITPY
ah - even weirder - ls /media/jerryneedell/CIRCUITPY shows all the files do the drive is mounte OK - just the GUI file manger is confused.
tidal kiln
so just the gui layer?
solar whale
closed an reopend file manger and it is now showing the files!!!
idle owl
Special.
solar whale
That is actuall "exited" file manger and close all windows then restarted
I never liked GUI's

@solar whale Just out of curiosity, which version of Ubuntu are you running? I'm going to be building a 17 system....

@tulip sleet FYI - I have always had USB erors generated by my backup drive - from what I read they are supposed to be "harmless" but now I wonder - see https://askubuntu.com/questions/832394/what-does-this-error-mean for some background
They are not the same erros we see with 3.0, but I wonder if there is a common tread.

@umbral dagger Thanks! Is there a significant improvement of 16.04?

@drowsy geyser Not really sure.. It had come out just before I built my system and had support for all the bits and pieces. It’s been working fine ... about 6 months now.

@solar whale That should work fine for this chip. If you end up bridging pins, just dap with solder wick to pull of the excess.

I’m going to do a rev two of the MetroWing once I get some feedback from @slender iron, making some nice art and maybe a few more dev-friendly widgets. If anyone can think of any useful features to add, or any other boards that would be useful for CP developers (or users?), let me know.

@slender iron i looked at the uf2-samd github and could not figure out what to do next.

the board comes with the bossa so you can just use the latest bossa to load bins

Now nothing... the "L" led is slowly pulsing
I have ttyACM0 but can't screen to it, and no USB drive is showing up
Well, if I single-tap reset just the power LED is lit. IF I double tap, pulsing red L.

@mortal wing @umbral dagger i was able to copy the my build of M4 onto the metro m4 board. i did a power reset and the board appeared as a mounted drive. I was able to connect to it using putty on COM3. I entered the REPL.1+2
pastel panther
@idle owl, @slender iron Any infor on which j-link to get? Does the jlink-edu have any benefits over the jlink-edu mini other than number of supported processors?
mortal wing
@fading solstice Sorry but I have no experience with circuit python
idle owl
@pastel panther I misread that. Sorry! I don't know the differences
fading solstice
i think i miessed the proper cable. the one in the box does NOT fit the metro or the jlink
idle owl
@pastel panther We all got the edu mini. But get the smaller cable that is suggested on the product page. All of us who just got the M4 anyway... Scott has the standard j-link
pastel panther
I figured I would just buy the edu-mini unless the non-mini had like chrome wheels or something
I am a sucker for shiny things
tidal kiln
this cable: https://www.adafruit.com/product/1675
will got straight j-link edu mini to metro
2x5 @ 0.05" on both ends
fading solstice
@tidal kiln thanks
tidal kiln
why the 2x10 @ 0.05" ???? 🤷
pastel panther
because it's teeny tiny and board space is $$?
I think i just have a thing for small boards
tidal kiln
but the j-link mini only has a 2x5 header, why provide it with 2x10 cable....???
idle owl
@tidal kiln I'd say maybe most things have the 2x10, or don't have the shield around the connector, but the cables are keyed so they're expecting the shields. Who knows. Just to baffle us perhaps.
split ocean
@tulip sleet and @idle owl (and anyone else who may know) do you think there will be a release of 'express' soon? Or already happened? I'm trying to link to the best possilbe place in my guide for people to get it.
solar whale
@slender iron just tried new bootloader - It works for CP - now to try arduino
umbral dagger
@tidal kiln I believe the 2x10 connector has more capability: swd + trace I think
idle owl
@split ocean The newest version is in the bundle, or available from the releases on the actual page.
umbral dagger
My SAME54Xplained board has both connectors
split ocean
perfect!
idle owl
@slender iron If you get a chance, can you upload the express.mpy to https://github.com/adafruit/Adafruit_CircuitPython_CircuitPlayground/releases
@split ocean Right now the standalone version with play_file isn't posted as a .mpy, but the current version is in the CP bundle.
solar whale
@slender iron woohoo! it works for arduino as well!
split ocean
@idle owl I d/l'd the 2.1 zip here https://github.com/adafruit/Adafruit_CircuitPython_Bundle/releases/tag/20171019
but don't see express.py or mpy in there.
in the unpacked zip that is
idle owl
/lib/adafruit_circuitplayground/express.mpy ?
split ocean
oh, now I see it
idle owl
That's why all the example code has from adafruit_circuitplayground.express import cpx because of that folder structure.
split ocean
makes total sense now, thanks
idle owl
No problem!
split ocean
i don't have the name in my head as circuitplayground_circuitpython ;)
or the inverse, actually
OK, so I'll test it w fresh install and that release version of the bundle. If that all checks out for me, that's what I will recommend in the guide for setup. Nice to have it all in the one bundle!

@stuck elbow I have thought the same thing...

I do but I have so many other files open with the same thing in it... I had to type it at some point though.
umbral dagger
Yay!

@split ocean Don't forget to either update your code or put somewhere in your guide to copy express to CIRCUITPY/ ... I think you have it as from express import cpx. If you've already changed it, ignore me! 😃

rebooting to fix linux 😥
solar whale
sad but true - get used to it for the time being.....

@split ocean Yep
split ocean
from adafruit_circuitplayground.express import cpx oh, is this the proper code markdown backtick?
yes it is. now I'm talking to myself
idle owl
@split ocean Single backtick is inline, triple backtick creates a code block codeblock

@tidal kiln the rest is the same (other than maybe some of the more esoteric stuff)

The make boardname clean command will erase the broken half-build right? Is that what that's doing?

yes - usually a good idea

In this case it would not matter since only he uf2 step is missing, but a good habit.

@stuck elbow At least only one will be on a board at any given time. But I hope we can avoid that.

@slender iron trying to convert Beagle output to pcapng using your script. No errors, but file comes out empty. Should I export the .tdc in a special way? I am using the latest (last commit 10 days ago) from your python-pcapng repo.
One thing I noticed right away while recording is that the 3.0 board is much, much chattier when idle than the 2.1 board.
idle owl
Has the uf2 bootloader been updated since yesterday?
split ocean
@idle owl @meager fog just so you know, everything works great on UFO calling the cpx commands with clean install of CP 2.1 and the latest bundle.

@split ocean That's great!

I'm not doing play_file at the moment, just play_tone btw
idle owl
Ah ok. Does it still fit your goal?
split ocean
yes, it's great, just what I need!
idle owl
Excellent!
I tried flashing the M4 and it didn't show up at all on the first try, but the second try, it mounted as CIRCUITPY! And I got my blinky back!
I made a debug build, time to try to connect the jlink again and see if I get the middle pane in Ozone.
I think it's still not halting. I still get a DAP error every time, whatever that is. And I have no idea how to even read any of this yet. But it's connected and I see the code. So cool!
And blinky still works on the other side of Ozone which it did not yesterday, so improvement!
Can't get to the REPL out of the serial connection though. This also happened yesterday. Reflashing my build didn't fix it.
stuck elbow
anything in dmesg?
tulip sleet
@solar whale I am having some success recovering from hosed USB by ps -ef |grep udev, find the base lib/systemd/systemd-udevd and then sudo kill -9 it. -9 may or may not be necessary. That brings back ability to use screen, but the 3.0 boards may still not respond.
Unplug the board while you are doing the above.
idle owl
How do I check dmesg
idle owl
thank you
stuck elbow
"systemctl"
you will see everything your computer did since it was switched on, look at the end 😃
for usb-related errors
idle owl
I can get the serial connection started, but I can't get into the REPL. It won't accept keyboard interruption or input. I don't see any usb stuf fin dmesg
tulip sleet
@stuck elbow thanks - I was doing sudo udevadm control --reload-rules, which was just hanging (which suggests udev was in bad shape).
haven't gotten used to systemd yet
slender iron
@tulip sleet yeah, export from beagle as csv
tulip sleet
@slender iron did that, but the resulting .pcapng was only 52 bytes long. Did you change any settings in the dialog box when exporting?
tulip sleet
goti it - tnx
slender iron
@tidal kiln what do you want my eyes on?
tulip sleet
@slender iron looking at the 3.0 USB traces, they're chock full of SCSI USB mass storage traffic when they should be largely idle. Also many ENDPOINT HALT requests. Not sure who's doing what: whether the Linux drivers are confused or the board is not answering properly.
slender iron
I bet the board isn't answering properly
idle owl
@slender iron Is there a newer version of the uf2 bootloader since the one we flashed yesterday? Or is that still the same
slender iron
yeah, dean fixed the arduino side
idle owl
But nothing changed on the CP side?
slender iron
I don't actually have a build
idle owl
ok
idle owl
I remember you mumbling about that 😃
I'm trying to figure out why I can't get to the REPL.
slender iron
😃
tulip sleet
@idle owl I could not get to the repl on a USB3 port on Linux. It works on USB2. If you have a USB2 hub you could interpose it if you have no USB2 ports on your Mac.
screen would connect, but I couldn't type or see output, and couldn't exit.
idle owl
We have one somewhere. I tried flashing yesterday's firmware but that does weirder stuff. I need to rebuild my local build. I cleared it with the intention of trying again.
If it fails again, I'll try the USB2. Thanks!
tulip sleet
This is not on an M4. This is just on a CPX. I have decided not to try wrestling with the M4 bootloader quite yet. But I believe this might be a USB problem, so using USB2 might be applicable to both.
idle owl
Ok every time, the first time I flash, it doesn't work. It appears to do nothing. If I put it into the bootloader again, drop the same firmware.uf2 on it, mounts as CIRCUITPY. This has happened every time I've flashed it, done some things with it for a while, and then tried to flash it again at a later time.
Serial connection works, still not taking input to get to the REPL. Going to try to find a USB2 hub.
Print statement in blinky code.py is working in the serial connection.

has anyone mentioned the flaky REPL interface on M4?
idle owl
Yep. I'm dealing with some REPL issues right now.
idle owl
Oh that I'm not sure of. I usually assume for a while that it's something I'm doing. I replicated it finally a few minutes ago, but I haven't filed an issue.
fading solstice
ok
dir(math)
[name'U, e'U, pi'U, sqrt'U, pow'U, exp'U, log'U, cos'U, sin'U, tan'U, acos'U, asin'U, atan'U, atan2'U, ceil'U, copysign'U, fabs'U, floor'U, fmod'U, frexp'U, ldexp'U, modf'U, isfinite'U, isinf'U, isnan'U, trunc'U, radians'U, degrees'']
idle owl
I can't even get to the REPL right now, but when I could I did dir(board) I got a lot of weird characters.
fading solstice
dir(math)Ab=math.cos(1) happens when I type a up arrow key twice
should get one or the other command, not both
idle owl
I haven't heard this issue yet.
fading solstice
i am on windows 10
idle owl
I haven't done any testing on Windows with the M4 yet. Or with any of these boards for a while.
I'll be back in a bit, need to do dinner.
drowsy geyser
@fading solstice I'm on Windows 10 too. I'm going to flash my M4 with CP built from source last night when I get home tonight, so if you're seeing something strange and need someone to replicate it, just let me know.
formal plover
@timber mango us Michiganders love CircuitPython!
fading solstice
@drowsy geyser try import math then dir(math). then type b=math.cos(1). that should work fine. now type up-arrow twice. i.e., up-arrow up-arrow. The command line should show dir(math), but instead show more stuff.
drowsy geyser
Ok, will do! Heading back that way now. 😃
idle owl
USB2 did not resolve the REPL issue. I still can't get to it.

@solar whale systemd-udevd was using ~100% of CPU after using a 3.0 board. I restarted it with sudo systemctl restart systemd-udevd
I awoke the system from sleep after a couple of hours of non-use.
solar whale
@tulip sleet thanks. sounds like you have been making progress.
tulip sleet
@solar whale stopping for now but will take a look at MSC details tomw. Looks like some kind of ineffective communication between host and device is generating a lot of useless traffic.
nocturne wren
@meager fog I love, love, love the CircuitPython Educator's Box. It makes me so happy. We played your CS4ALL video for 80 high school and college women during an all day hackathon on Saturday for two humanitarian causes. Folks loved the eyeballs. 😄
solar whale
@tulip sleet great work - Goodnight!
@tulip sleet wow sudo systemctl restart systemd-udevd caused an immediate mount of METROM4BOOT - It had not been able to do that . Very nice!
@idle owl Are you using a Mac - I have had few REPL issues with mine on MacOS. BTW I think I have a reliable workaround for the "unable to halt" problem wiht J-Link. What I found works is to disconnect the USB (power via 9V) then manullly enter bootloader and then try Jlink. After it connects, I can plug the USB back in and get to UF2 drive or REPL.
idle owl
Hmm. I am using a Mac yes
solar whale
still no REPL
solar whale
ah - have you tried it with the J-Link disconnected.
idle owl
Yeah I usually disconnect it before doing anything. I haven't had it connected since I checked earlier to see if I could see the code in Ozone
I assume it'll interfere 😃
slender iron
@fading solstice dan is looking at the USB issues now. we know its flaky
solar whale
Dan is onto something - the restart of systemd-udevd really helps!
@idle owl how do you connect to REPL - screen /dev/tty.usbmodemxxxxx 115200 ?
solar whale
I just plugged mine into my MAC and it took a few tries for connection to work. but it eventaully did.
I am using DEBG build
idle owl
It connects just fine, but it doesn't accept ctrl C to get into the REPL or any other input to interrupt the serial connection. If I add a print statement to code.py, it prints just fine
If I save code.py from an editor, it does a softreboot even
solar whale
hmmm - maybe it is just ready for baby steps....
idle owl
lol. Along with fdsafdsafdsa that I typed earlier trying to see if anything would work....
Like it stored all the ctrl C I did....
idle owl
😃
idle owl
hmm.
solar whale
control-C ends it and Iget control back.
idle owl
I copied it back and imported it and it ran. Did ctrl+D to get it back to the serial connection, and then I was still able to get back to the REPL.
Going to try disconnecting it now and seeing if I reconnect if it works
solar whale
yesterday was a long time ago 😉
idle owl
😄
solar whale
Congratualtion on your first build and getting J-link going!
idle owl
Thanks! It still gives me the halt errors, but it's a start!
solar whale
the halt errors are common - you saw my post - let me know if that works for you.
idle owl
I copied the suggestion out so I have it, I think I'll try it tomorrow
solar whale
but you need the 9V supply
solar whale
all in good time - you are making great progess - so much of this has to be experinced rather than demonstrated.
For example. the Jlink is an incredible tool and it will take a lot of poking and proding to get used to it either in Ozone or GDB but there is no way to learn besides doing it.
idle owl
Yeah for sure
solar whale
The metro_m0 says the supply should be 7-9 V so I guess a 5V supply os not enough. too bad. they are more common. I was glad I had a 9V available.
idle owl
I have a friend who does this type of thing daily, I told him he's on for teaching me, but he lives a ways away and it'll be a while before I see him. So I'm on my own for a while 😃
idle owl
You too! Have a good one!

Hi 'all. Blink was still running solid. Screen was still connected. CTRL-C got me the REPL prompt and it worked fine.
idle owl
Nice!

using up/down-arrow appends to the existing cmd line rather than replacing it

cunning crypt
@umbral dagger Reading that makes me think your M4 is just drunk.
solar whale
@umbral dagger I have seen both issues
idle owl
Less obvious because there's a lot of 2 letter pins in dir(board) so there's only so many random combinations of 2.
umbral dagger
output of REPL results seems fine
But there seems to be an issue with the readline equivalent. I.e. manipulating the command line
solar whale
Not clear if it is on input or output - if output it may be one issue. If input it is two....
solar whale
yes - so Iam hopeful it is all related to output of strings.

Backspacing and correcting worked
left/right-arrow appears to be ok
solar whale
Just don;t look at the screen 😉
umbral dagger
but left-arrow "too far" and type and it messes up... appending copies.
solar whale
I thought about entering an issue, but I'm not even sure where - Thought it best to give it some time....
Now it is really time for bed - Good night all.

I'm wondering if it might be my terminal emulation.
hmm.. screen claims VT100 compatibility which is what CP looks to be assuming/requiring
idle owl
@river quest They look great!
river quest
it's like a mirror of all the cool stuff we are doing, so thank you everyone here!
formal plover
And thank you @river quest!!!
Might just have to make the large banner my Twitter banner.
umbral dagger
@formal plover Ohh.. good idea.
formal plover
Thanks @umbral dagger! Mine is up
umbral dagger
So... screening in doesn't work anymore... and I can't get the BOOT drive (doubletap reset) But CIRCUITPY shows up fine on reset. I can edit main.py on the board.
It isn't auto-reloading, but reset will pick up the changed code
umbral dagger
@formal plover So's mine. I did my facebook as well
Enyone that knows me will be shocked that I'm a Python fan now!
Though to be fair, I'm a circuitpython fan
pastel panther
Howdy folks! I'm finally done with post-work things and can play around with my new toys!
drowsy geyser
I thinik @idle owl infected me. My REPL isn't working now....
drowsy geyser
@pastel panther What new toys do you have?
pastel panther
a oled featherwing, metro m0 and metro m4
drowsy geyser
Nice! UPS just dropped off another Adafruit box for me. I need to see what's in it. 😃
pastel panther
doing a 2.x build on the metro (cause I've already done one successfully on my feather), then 3.0 on the m0, then with any luck 3.0/master on the m4
I'm about to pull the trigger on a j-link as well
drowsy geyser
If you get the JLink join the crowd figuring out how it works. We're making progress!
pastel panther
nice
Did anyone buy the non-mini edu? I'm thinking of spending the extra bucks to get a bit more speed and processor support
idle owl
Dan and Scott have them because of the commercial use case. I think the rest of us got the mini.
drowsy geyser
@pastel panther I'm thinking of getting the non-Edu JLink so I get a full license for the debugger.
@idle owl Bingo. That did it.
Thanks!
drowsy geyser
G'night @idle owl
pastel panther
night!
drowsy geyser
@fading solstice Double up-arrow bug confirmed. I'm running: Adafruit CircuitPython 3.0.0-alpha.0-26-g536bcb4 on 2017-10-20; Metro M4 Express
pastel panther
What's the repro?
dear lord, I forgot how much I missed dir() since I left python land for ruby land
drowsy geyser
import math, dir(math), b=math.cos(1), then double up arrow. It should display "dir(math)" but instead displays "b=math.cos(1)<gibberish>dir(math)"
pastel panther
sure. I'll take a look after I get 3.0 on the m0
drowsy geyser
Ok. No rush. @fading solstice had asked me earlier to replicate it, so that's what I did. 😃
pastel panther
I'm itching to get the m4 going but I'm trying to be smart and take it step by step rather than jumping to a new branch and board at once
drowsy geyser
@pastel panther I got 3.0 to compile last night. Trying to work up the nerve to flash it to my M4. 😃
pastel panther
there it goes, I had to get the 3.0 submodules
just doooeeeet
wait, didn't you say you repro'd the bug on a m4 with 3.0? Was that not your build?
@drowsy geyser if so, just save the current uf2, right?
drowsy geyser
@pastel panther No that was the "latest commit" build as of Saturday evening. I just flashed it with my build from source as of last night.
drowsy geyser
@fading solstice Also replicated the bug on my build from last night's sources.
@pastel panther MacOS?
pastel panther
ya
drowsy geyser
See if /dev/tty.usbmodem1412 is there. 😃
I noticed on my Mac that it would often renumber the tty.
pastel panther
no dice
pastel panther
tried that, no luck
I'll try 2.1 again. It will go into bootloader mode so I got that going for me which is nice
drowsy geyser
Drat. My Mac is dead or I'd try to replicate for you.
pastel panther
yup, that worked, tty.usbmodem1411 shows up after putting 2.1 back on
drowsy geyser
That's ... unusual.
drowsy geyser
That is really strange. I guess I've been lucky with my Windows 10 environment so far.
drowsy geyser
No, I put it on the M4.
pastel panther
If the feather works, I'll try the m4
drowsy geyser
Ok...
pastel panther
same thing on the feather m0
drowsy geyser
Huh. Now you have me wanting to build an image for the Feather M0 to see if I can replicate the USB problem under Windows....
Maybe @slender iron can try, since he has a Mac, too.
pastel panther
I mean, it can't hurt to try if you have a board lying around. No rush though
yea, I'll ask Scott tomorrow. Might also poke at the code to see if I can find an idea of what the issue might be
Did you have to do anything special to get 3.0 on the m4? I though I heard of people saying that they had to use bossac
speak of the devil! Hey @slender iron do you know of any trouble loading 3.0 on m0 boards from a mac? On the feather and metro both, my tty.usbmodem1411 disappears after flashing
slender iron
@pastel panther I've only tried loading 3.0 on the m0 via jlink
pastel panther
@slender iron Ok, I'll poke it with a stick until it gives up it's secrets
slender iron
dan is looking at the usb stuff more tomorrow too
I definitely saw the incorrect output on the m4
pastel panther
do you thing it's a general thing and not a m4 specifc issue?
slender iron
it seemed m4 specific to me but I'm not exactly sure
most of the usb stack is shared
pastel panther
where would I look to poke around at that?
pastel panther
ok, thanks

I'm looking at the Circuit Playground Arduino IDE examples with an eye toward reproducing them in CircuitPython, and I'm stumped. One of the audio example sets is a speak-and-spell sort of thing that calls a function CircuitPlayground.say() or somesuch. But when I look in the .h and .cpp files, there's no implementation of .say. Just a bare reference in the header. Anyone got a clue offhand?
pastel panther
Can you point me to the code/example in question?
dry carbon
Hello all ❤
glacial bronze
er, I just yanked them out of the Arduino IDE and CP library folder, one sec
File --> Examples --> Adafruit Circuit Playground --> Speech, then etc. Talk_US_Male
ah here https://github.com/adafruit/Adafruit_CircuitPlayground/tree/master/examples/Speech/Talk_US_Male
https://github.com/adafruit/Adafruit_CircuitPlayground/blob/master/utility/Adafruit_CPlay_Speaker.h has the reference to the say() function
the matching .cpp doesn't include the string "say"
oh flip, never mind. The code I'm looking for is in talkie.cpp. But I'm not sure where that's included into the sketch
pastel panther
yea, I don't immediately see a refernce to talkie. The sketch compiles though?
glacial bronze
Yep. I haven't tested it on the board, though
Let me actually install the SAMD board version and see what that looks like
Now it doesn't compile
#include "sam.h"
^
compilation terminated.
exit status 1
Error compiling for board Adafruit Circuit Playground Express.
That does not seem related
glacial bronze
I literally just pulled them fresh. I guess I can try restarting the IDE
Nope, same error
pastel panther
I'm assuming you can't compile blink.ino either?
glacial bronze
That would be right
pastel panther
You might try turning on verbose compile output if you haven't already
I would try and find samd.h in your path and verify that it's referencing that dir during compile
glacial bronze
There is no samd.h in the Arduino packages\AdaFruit folder
pastel panther
I came to the same conclusion. Sorry, I don't think I'll be much further help
pastel panther
./libraries/asf4/samd21/include/sam.h
./libraries/asf4/samd21/samd21a/include/sam.h
./libraries/asf4/samd51/include/sam.h
that's in Documents/Arduino on a mac, not sure where the windows equivalant would be
glacial bronze
It looks like it's an Arduino file that goes missing sometimes. Maybe part of the problem here is that my ArduinoData folder is real old and the IDE has been updated over and over without actually wiping that folder clean
pastel panther
when all else fails, nuke it from orbit and re-install
