Either way is fine I think. I haven't had to remove those allocations yet so it can't be too bad

yes, maybe I'll just leave it. It appears that a long-running event handler is not as problematic as one might have thought.

@craggy galleon the cookiecutter error has been fixed. if you run it again, make sure to answer yes to the re-download question. thanks for bringing the issue to our attention!
craggy galleon
Ill give it a test run shortly. Thanks heaps
idle owl
@gilded cradle @onyx hinge Either of you still on the clock and have a couple of minutes to review a PR?
gilded cradle
Sure
raven canopy
@craggy galleon as a peripheral affect, i'm currently looking at writing some tests for changes to our cookiecutter. this would have been easily caught.. 😄
gilded cradle
Which pr @idle owl ?
gilded cradle

idle owl
@gilded cradle You can merge it - Limor already ok'd someone else reviewing it. I initially thought she wanted to, but she headed out so I verified with her before she left.
gilded cradle
ok
idle owl
Thanks so much for the super thorough review! I really appreciate it.
gilded cradle
You're welcome. I didn't test it, but just looked at it closely.
idle owl
I tested it when updating the guide because I had to do Mu screenshots of everything anyway.
gilded cradle
Excellent
gilded cradle
Yeah, easy enough to fix.
gilded cradle
You're welcome!
craggy galleon
@raven canopy thank you for the fix. Works now. I also wanted to note that it puts the older versions of Python3 as supported (3.4, 3.5) rather than newer ones (3.7,3.8). Is this something that should also be updated?
raven canopy
@craggy galleon i don't have a confident answer to the setup.py referencing 3.4/3.5, beyond the fact that CircuitPython (via MicroPython) is based on the 3.4 syntax. There are quite a few popular things in 3.6+ that we don't really support. Granted, Blinka users will have the newer versions available... @idle owl might have a more concrete answer.
simple pulsar
I've noticed two very minor differences on the Circuit Playground Bluefruit wrt to touch pad inputs. I doubt these are CircuitPython specific but I am running 4.1.0 vs 5.0.0-beta.2. The first difference is I think the default sensitivity is a little different. It's subtle but I think the CPB takes more to register the input using a finger. This is based on comparing a single pair of boards so far... There's a few questions here, is the auto-calibration at startup working? Is there expected to be a difference with the nrf chip? Is this difference significant enough to affect (existing) projects?
simple pulsar
Second one is more fun. I've got the speaker active and I'm making some beeps on it. I'm also using touch pad A1 next to the AUDIO pad. If you put your finger firmly across A1 and AUDIO then it makes a curious sci-fi type noise. This is probably just some combination of the amplification of signal on A0/AUDIO being more sensitive and different approach to capacitive input between the two chips? This code can be used to demonstrates it: https://github.com/kevinjwalters/circuitpython-examples/blob/b590ddf935f10983ca7e99068ce8ad328d00db06/cpx/cpx-reaction-timer.py - press A1 whenever the first NeoPixel comes on or it beeps and try firmly "bridging" over to AUDIO pad on CPB with finger.

typical SCK scope trace while playing MP3 from SD card
ruby atlas
@onyx hinge is that good? 🙂
onyx hinge
@ruby atlas It is okay I guess. danh is concerned about things that block for 1ms and this is a lot more than that (all the time that SCK is pulsing, it's in a background task and blocking other background tasks) but on the other hand it's a lot less than 100%
(actually it's blocking more than that, because it also has to decode MP3, this is just showing the SD transfer time)
it's mostly "whee, I know how to use my o'scope" 🙂
ruby atlas
I would like to play with scoping more. I haven't used any modern scopes.
Is the concern that >1ms of background will affect the Soft Device?
(BTW, What the heck is the Soft Device in the NRF port?)
onyx hinge
@ruby atlas Soft Device is the code from nRF that makes bluetooth work, is my understanding
ruby atlas
Right, but i'm wondering why it's called that 🙂 I guess I should google.
"SoftDevice S132 is a high performance Bluetooth 5 qualified protocol stack for the nRF52810 and nRF52832 SoCs"
onyx hinge
I assume because it's Software that implements the bluetooth Device ? idk
ruby atlas
Also "The SoftDevice contains the Nordic Bluetooth code. It's a piece of firmware that is flashed in a certain area on the microcontroller. When you have flashed a SoftDevice you need to adjust your linker settings of your code. See the examples for suitable linker files."
onyx hinge
I just wish I knew how to disable SoftDevice when debugging via jlink
ruby atlas
Ha.
onyx hinge
you too eh?
ruby atlas
hmm, wonder if it's always enabled now.
But either way, I feel like Scott or Dan know how to avoid the SD being enabled if you don't want it while debugging something that really doesn't need it.
onyx hinge
seems like it is always enabled now
idle owl
@tulip sleet I realised too late, I should have included some kind of friendlier error in the Circuit Playground library for when importing the Bluefruit-only features on Express. I'm adding it now, I don't expect it to be included in 4.1.x, but we should include it in 5.x.
Also realised that if I add those errors, the code I have to update one of the examples to work with both CPB and CPX no longer works because it uses hasattr and they'll both have it now.
So that update will no longer work.
There's one thing that CPX has in dir(cp) that the CPB does not, but it's wholly unrelated to the program. Keeps the code clean though, so I guess I'll run with it and comment it instead?
raven canopy
could you use os.uname()?
ruby atlas
@idle owl what about a class property has_bluefruit on both, set to False on cpx, True on cpb? That could make example code easier to read than try/except.
idle owl
@raven canopy Don't want to complicate the code any more than necessary.
raven canopy
👍
idle owl
@ruby atlas Maybe? this is literally the only example that it's an issue though.
Anything else can be written specific to each board really easily, or has no issues working on both.
What I wrote works. I can comment it and it'll be fine.
ruby atlas
>>> os.uname()
(sysname='nrf52', nodename='nrf52', release='5.0.0', version='5.0.0-beta.0-112-g17c8356b8-dirty on 2019-12-05', machine='Adafruit Circuit Playground Bluefruit with nRF52840')```Yeah, that's cleaner.
idle owl
This adds one line of code to check if the touch_A7 is available or not, and calls it Express if it is. It's pretty clean.

Hi experts, I'm trying to convert a float value from time.monotonic() into two integers which I want to transmit on IR.
How would you suggest I go about doing that?
I guess the part before the decimal are just int(x), but what about after? The number of decimals I guess, three would be nice, two can be ok if need be.
Ooops, wrong room, I think. Sorry 🙂

@timber mango One way is math.modf() it's present in my M4 Feather build https://docs.python.org/3.5/library/math.html#math.modf

@idle owl Is there some work going on with offering a single import line or cpx / cpb object that works (mostly) on both CPB and CPX?
idle owl
@simple pulsar from adafruit_circuitplayground import cp and it detects which board and imports properly.
lone axle
Still needs help pages and a few other finishing touches but getting pretty close now, I will probably get the code up today or tomorrow. All of the main functionalities from the iOS app are working:
https://youtu.be/f0aQ4DjcFx8
idle owl
@lone axle That's great! Please let me know if you need testing. I have no idea how to build it myself but if you can get me the packaged app, I'd be happy to test it.
lone axle
@idle owl Thank you 🙂 I will definitely need some help testing on different devices. I'll include a built APK file in the repo once I put it up.
idle owl
Excellent.
simple pulsar
@idle owl Is the new cp fully compatible with code written for cpx object? Is that going out for 4.x as well as 5.x? Perhaps all these questions are answered already somewhere?
Is the cpb been deprecated now? I've got some CPB only code that'll probably go out in a guide in a week or two, hence my interest.
idle owl
The old way works as well, but we're wanting to use the cp method going forward so all code works on both. Yes, it is fully compatible. It simply checks the board and imports the module, so it's basically cpx/cpb behind the scenes. The old way isn't necessarily deprecated, as it still works. @simple pulsar
It's already in 4.x and 5.x.
That was the main reason for 4.1.2
These questions are not really answered anywhere, you're not missing anything. I'm updating the main guide for the library, but we're not expecting all existing guides to be updated.
I can update the README with this information.
solar whale
@idle owl do I have do do anything to my forks of library repositories with respect to the change over to github actions?
idle owl
@solar whale Presumably do a pull once everything is merged. I don't think there's anything you specifically need to do.
solar whale
Thats what I was hoping! -- Thanks
ionic elk
@slender iron @tulip sleet do I need to do edits to the UF2 generator for stm32 before I should expect it to start working properly? The current build process creates one, but the Meowbit bootloader doesn't even recognize it (compared to UF2s they provide for micropython).
I've got their emails now, so I can reach out if this is something that's more likely on their end, but I want to make sure there's nothing more I need to do first.

@idle owl and anyone else interested / willing to test. The repo is up now and there is a debug build APK in the root of it that you can download to install on an Android device. https://github.com/FoamyGuy/Android_Bluefruit_Playground
lone axle
There is a direct link to the APK in the readme file now. Anyone with an Android device and a CPB who is willing to try this out please let me know how it goes and which Android device you have tried.
quasi fjord
@lone axle what firmware goes with the app?
lone axle
@quasi fjord this pdf has the full details on the app: https://cdn-learn.adafruit.com/downloads/pdf/bluefruit-playground-app.pdf?timestamp=1577363264 and the firmware specifically is here: https://adafru.it/HCh
I will update the readme tomorrow with that information.
quasi fjord
looking good on a Pixel 3a. The NeoPixel page could use a page indicator. I didn't realize there were other modes until I read the guide. And for your TODO list, the accelerometer page doesn't let you manually rotate
quasi fjord
Android 10 on the Pixel 3a. It also looks good on a Nexus 5X running Android 8.1.0
a quirk on the button status: the switch shows an update animation when I first hit either A or B
quasi fjord
Looking good on a Samsung Galaxy Note 4 too, Android 6.0.1
lone axle
@quasi fjord Thank you 🙂 I'll get those added to the todo list. If anyone here has a CPB and an iPhone and is willing to help out. A short recording of the Accelerometer module in the iOS would be most appreciated. In particular I'm trying to see the behavior of manually dragging the 3D model vs. the Accelerometer data moving it.
solar whale
@lone axle just tried your app on an older ZTE android phone -- v7.1.1 -- worked great!
one minor issue is that "Disconnect" does not seem to work ??
lone axle
Hooray! Thank you. Yes that is correct I need to hook up the disconnect button in the top left corner of the modules list page. For now tapping the notification in the notification bar is the way to disconnect and shut down the bluefruit service in the background.
solar whale
once I am disconnected -- how do I get the App to restart and rescan?
it just comes back up but is not connected
lone axle
@solar whale Re-launching it from the home screen / app drawer should initiate a new scan I think. If not I believe there is a refresh button in the top right of the pairing activity that you can press to manually start a scan
Oh, I see on my end that re-launching is not working quite right
solar whale
ok - np -- tryin g to record iphone accel screen -- now trying to upload
Accel. Demo
lone axle
if you use the back button on your device you can work your way back through closing things. Once everything is closed the next time you launch it should take you to pairing screen where you can scan/connect
solar whale
sorry about the beginning of the recording -- is that what you needed
lone axle
Oooh, Thank you. Is there any way to show screen touches?
solar whale
I have no idea 😉
lone axle
I'm trying to figure out how the interaction between manually dragging the 3D model vs. the incoming accel data moving it
like if you manually drag it does that override the accelerometer position for a few seconds or something?
and then just go back to matching the accelerometer after some time?
solar whale
if you manually drag it, taht seems to just provide a starting point for actually moving the CPB.
the accel only seems to give relative position
solar whale
all the motion in the movie was from moving the CPB
lone axle
Ah I think I understand. Can you record one more where you drag model on the screen a bit and then move the physical device a bit?
solar whale
ok -- just a sec
first part is dragging -- left it on side view the started moving the CPB
lone axle
Awesome. Thank you.
It's like an extra adjustment that allows you to change the angle you give the board from.
solar whale
yes -- seems that way --
lone axle
The 3D Model was new territory for me so I'm not sure exactly how to implement it, but I should be able to figure it out now. Thanks again for testing on the Android device as well.
solar whale
You've done a great job -- so quickly -- glad to be of help.

@solar whale Its a bit of a balancing act on android with all of the different screen sizes and densities. But should be able to get them covered with a good set of differently sized assets. Thanks again for the help, i really appreciate the feedback.

Are there timer allocation issues that the pin code above would reveal that the data sheet would not? I've been meaning to make an all-purpose version of that code for all of the major features... I2C, UART, SPI, etc

@ivory yew @idle owl has a script that tries all combinations on an existing board def

you could modify it from the pins defs in microcontroller.pin

I spent most of my career as a solo programmer on embedded systems -- It has been a struggle to get used to a large opensource project like this. I appreciate the need for standards, but bristle at some fo the nit-picking. My response to lint is often "If it bothers you, then you fix it" 😉
but then I go ahead and do it ...
onyx hinge
I am going through that a bit myself right now, but I'll try to get through it
some of these rules are so contrary to my personal style that it's hard to be willing to adapt
ionic elk
do you guys use a lint for your C code?
I thought that all that was basically covered by compiler warnings these days but I want to make sure I'm not missing out on anything
ivory yew
afaik we don't use clang-tidy or anything like that.
onyx hinge
@ivory yew though tannewt has looked into doing it
ivory yew
that's certainly possible.
onyx hinge
@ionic elk the compiler errors are pretty stringent for "real" problems but don't do much for "stylistic" concerns. I've been able to run clang's scan-build static analysis and it found a few interesting things but not many.
clang can't compile CMSIS so it's not possible to build anything but the Unix port with it
(I should have probably chosen different language so it doesn't sound like I'm disaparaging "stylistic" checks. They're important, because a project needs to speak with one voice as it were)
ionic elk
was just reading https://barrgroup.com/embedded-systems/how-to/lint-static-analysis-tool out of curiosity. The compiler by default doesn't highlight the example it provides.
onyx hinge
I figure the open source tools incorporate the bulk of the useful warnings from proprietary tools
ionic elk
Having just spent some time chasing down a pointer error I'm feeling like I could use a little extra check
onyx hinge

hum unexpectedly I am getting hangs when I use audiomixer .. in shared_dma_transfer!!
which is ??? because I believed I had fixed the hang
manic glacierBOT
onyx hinge
but even before it does that, it plays back "stuttery". there may just not be enough CPU power left over after spending all that time on SD card reads
shouldn't the M4 DAC go up to nearly +3.3V?
seems like it clips at 2.7v
it is drive strength or something, on headphones it clips at more like 2.6v
audiomixer playing a 768-sample, 10-repetition sine wave.
I think audiomixer may have an assumption somewhere about the relationship between its own buffer size and the underlying samples' buffer sizes? A 1024-sample, 10-repetition sine wave plays fine.
sine wave clipping. headphones and speaker disconnected from pygamer.
manic glacierBOT
onyx hinge
DAC is characterized for max load of 5kOhm, actual load is 200ohm in pygamer according to schematic, probably explains clipping 😕
errant grail
@onyx hinge There are two 100-ohm series resistors leading to the PyGamer's amplifier after a 4.4K-ohm voltage divider, but the amp's internal impedance is 10K-ohms; shouldn't be an issue.
The DAC is seeing a 4.0k-ohm load caused by the voltage divider and the amp's internal resistance. That is close to the 5k max load spec as you noted.
onyx hinge
this is the part I was looking at
ionic elk
@meager fog @slender iron evaluating my priorities today as Meowbit weeds wrap up. Current shortlist is:
- full optimization test across all chips/peripherals
- address remaining busio issues like one-line SPI, etc
- internal filesystem improvements & better package management
- Add espruino wifi/pico, Discovery F405
Anything you'd like to add/move around? Happy to help with @onyx hinge with audio DMA stuff if that's high priority, it's still on my basecamp todo.
onyx hinge
doesn't that create a 200 ohm load on A0?
errant grail
@onyx hinge Ah. That's a horse of a different color.
onyx hinge
same code as the "clipping" example, but over on a metro m4 express
errant grail
^^ Yes. I missed that on the schematic.
onyx hinge
np, you found 2 100-ohm resistors and I wasn't any more specific..
errant grail
But I'm more confused after looking at the M4 DAC's output minimum spec:
onyx hinge
200 ohms would exceed the minimum?
errant grail
so they're saying that's the lowest resistance allowed, not the load. Okay.
onyx hinge
that's my take
onyx hinge
I don't have a decade box or I could be more specific
errant grail
sorry about the distraction. Was confused by an earlier reference in the spec sheet that said the DAC outputs had "high-drive capabilities."
past herald
For what it's worth, 5kOhm is indeed on the higher side... often you'll see more like 50-100k specs in garden-variety DACs.
onyx hinge
@errant grail I appreciate your time, thank you!
errant grail
@errant grail I'm glad you're working on this. I'm starting to use the PyGamer/Badge as a quasi-universal front panel for projects and hadn't seen this limitation yet.
The PyBadge doesn't have a headphone jack, so the schematic is different:
onyx hinge
I said way back on 11/29 that I could play 2 mp3s through audiomixer on nRF. I think it was that "test.mp3" (40kBit/s 44.1kHz, stereo) and that I was using i2s audio out.
and of course it was from flash, not SD
samd51's clock speed is way higher than nRF52840 isn't it?
onyx hinge
looks like I reformatted the 52840 feather that had that code on it, for working with seesaw and kmk. but that tells me to try next with that same file on samd51
errant grail
@onyx hinge I recalled testing M0 DAC output drive two years ago for a JP AM radio transmitter project. My notes confirm that distortion increased when the load resistance dropped below 5k-ohms. Wish I had taken some o'scope pictures.

The sound on a tonewheel Hammond organ is varied through the manipulation of drawbars. A drawbar is a metal slider that controls the volume of a particular sound component, in a similar way to a fader on an audio mixing board. As a drawbar is incrementally pulled out, it increases the volume of its sound. When pushed all the way in, the volume is decreased to zero.[16]

@solar whale your note in github is that I can test it without needing the board, right?
solar whale
@ionic elk yes -- just a quick "sanity check" but I'll be happy to test it.
prime flower
@solar whale - the device address should be in the frame header payload... Are you giving your nodes unique names. This is interesting
ionic elk
I didn't dig down too much since I assumed (mistakenly?) from your post that it was hardware-requiring code
solar whale
@prime flower yes -- the node id is in the header. It's more a matter of collisions
without interrupts - the time not listening can become an issue

Yep!
not ideal , but fwiw the chances of 2x lora nodes tx'ing at the same time is relatively slim. still, we need to quantify a packet loss % we deem as reliable for this PR.

@onyx hinge try updating, should be fine, works on my machine (TM)
I'm curious if the firmware is spending time polling the server (why would it be...the wifi conn is established prior to SNTP being set) or if it's a predefined NTP timeout

TZ=UTC date --date=@946684800
Sat Jan 1 00:00:00 UTC 2000

prime flower
🙂
Ok, so it's waiting for it to increase past that timestamp since that would be the earliest date possible?
onyx hinge
It might start counting at zero seconds from bootup, but then when it gets back an NTP packet it updates to "now", which is always after 2000?
prime flower
yeah, I wonder if there's a way to handle this other than polling it
onyx hinge
I suspect not
it looks like it sends an NTP packet "shortly after" getting on the network. and here it reliably gets a packet back "shortly after that"
it has to do things like DNS-resolve the NTP server too
here it's >10s from starting the DHCP process to getting the NTP packet back, but I'm not sure how much of that is after is_connected starts being True

``` I think that it became connected right after that first ARP request above, then a 6s pause, and then it starts doing the NTPbecause of my network configuration, DNS packets are not visible here

@pastel panther can confirm, is sweet
onyx hinge
but .. it's supposed to wait a random length of time after start for the first (S)NTP poll, so it may just be doing its job @prime flower
also 5000 is not 5 minutes in milliseconds, but who is counting 🙂
prime flower
RFC states it could be 1<delay_mins<5, I wonder if decreasing the delay would be OK if its within the params. I won't fiddle with it past there, the NTP needs to be set once in user-code and having a ~10-15sec delay on bootup once isn't terrible
onyx hinge
I'm not sure it's the full explanation, either, because it looks like the DNS query would happen, then the random delay, then the NTP query
prime flower
@onyx hinge what networking setup are you running to obtain those frame captures - wireshark, something else?
onyx hinge
@prime flower just tcpdump running on my openwrt router
tcpdump -n -i br-lan 'ether host a4:cf:12:55:f9:14'

(asking bc I'm going to be setting up a router soon and that's super useful for me)
onyx hinge
only problem is I have to reset it from time to time or my internet speed goes down by 90% 😦 😦
onyx hinge
the hardware is Linksys WRT1900AC which was a cast-off from a friend but still pretty good spec
but yeah I think you are going to just have to poll, as there's a deliberate random delay (and maybe some other less deliberate delays on top of that, it's not clear)

hey @idle owl this build is failing due to a supposedly missing module docstring, which seems to be coming from adafruit_circuitpython_thermalprinter/__init__.py but I'm not sure exactly how to fix it.
Do you know where this missing docstring is supposed to go? Maybe outside of the __init__ method ?
idle owl
@pastel panther I would try adding one to the beginning of the __init__.py I guess. Is that not fixing it? Could also be here https://github.com/adafruit/Adafruit_CircuitPython_Thermal_Printer/blob/9dd720585e5ba12f6a9b27b967cfbcea015df64b/adafruit_thermal_printer/thermal_printer.py#L125 maybe? I'm guessing though.
pastel panther
@idle owl Hadn't tried it yet. I'll give it a go
idle owl
@pastel panther Might be because there's extra whatnot in __init__.py that it requires a top level docstring.
pastel panther
@idle owl Ya, that's what I was thinking but it likes that even less 🤔 (may have done it wrong)
idle owl
bleh. hmm.

This seems to suggest that we're on the right track

simple pulsar
@onyx hinge What's the interest in ntp here and why is it problematic if it has a laid-back startup wrt to polling?
simple pulsar
@prime flower My knowledge here is from 15 years ago but if you want an instant setting of time at boot time from ntp for a device that has no RTC clock then isn't a one-off ntpdate the typical solution followed by starting up the daemon as needed? ntpdate won't have issues with big time stepping too. Ah, reading more into this thread it looks like you are not using a bog standard ntp distribution here.

@prime flower @onyx hinge Jan 1, 2000 is special to CP/SAMD at least https://circuitpython.readthedocs.io/en/latest/shared-bindings/time/__init__.html
Not sure why WiFi.cpp follows that. NTP time should technically be relative to Jan 1, 1900.
Does anyone know if UDP is fully implemented in ESP32SPI? Might be handy to test an alternate path for NTP etc. I see some code there, not sure if it's all there and tested.

@prime flower I suspect espressif has a 'bug' where they won't do the first SNTP until after the minimum interval elapses from startup https://github.com/espressif/esp-idf/blob/826b9f63805ab9b955cd2129673117080c6d29ba/components/lwip/apps/sntp/sntp.c#L100

@onyx hinge all imx rt boards have to have qspi flash because it stores the code externally
onyx hinge
ah I read too much into what gragib said about needing to add SPI flash
slender iron
it is only 2mb though. artur's is 8 mb
Flash is accessed by FlexSPI, which maps the entire Flash into the M7's memory. Any location in the Flash chip may be read as if it were ordinary memory. Caching is used, so often there is little performance loss. But a cache miss does require many clock cycles to fill a cache row from the Flash chip. Normally only large tables, startup code, and other resources which are not speed critical should be accessed from the Flash memory. String constants may be placed only in the flash using F("string") syntax.
onyx hinge
code and CIRCUITPY in the same flash device seems more like non-express configuration to me
slender iron
ya, in the port its marked "internal"
but it has the size of an express board since it is an external chip
onyx hinge
what kind of split would make sense, 1/1? 1MB code for circuitpython core should be more than ample, you'd think.

@slender iron @solar whale the only thing I thought of when I read that, was whether or not they had tried an unmount via the CLI.....ie, is something going on with the UI that's hanging and not actually the USB/filesystem subsystems of the kernel?

@sly falcon interesting -- if I do a CLI umount, it unmouts just fine, but if I then unplug it the GUI does complain about it not being ejected -- umount != eject -- but it still works ok.

oh interesting....I hadn't thought about the UI not noticing that the filesystem had been unmounted

pixels[0] = int((0 * (9 - step) + 255 * step) / 10), int((0 * (9 - step) + 41 * step) / 10), int((255 * (9 - step) + 147 * step) / 10)
general formula is int((start * (number_of_steps - 1 - step) + end * step) / number_of_steps) for each component

@stuck elbow this is what i got so far the end must be the warm white and iff possible all off with keyboardninterupt
i even want a button to start the script as you turn the xbox wall on ant iff possible push it again or another button to play the opposite in reverse

@slender iron Where is usb_hid coming from? CircuitPython?
stuck elbow
@idle owl it's in C built into the firmware
idle owl
Ok.
slender iron
👍
and its been in the firmware a while. only the library is changing
nice post @gilded cradle ! Its amazing to me that you just started in the community a year ago. 🙂
gilded cradle
Thanks @slender iron ☺️
idle owl
@slender iron Merged your PR.
slender iron
ok, will update the guides

@slender iron Did you get this one: https://forums.adafruit.com/viewtopic.php?f=60&t=160679

That's fine, I was going to reply thanking them for their input. But wanted to make sure you had it on your radar.

Ok

Hi y'all. I created a pull request for the PyPortal library to orient a mix of portrait and landscape images correctly from multiple fetch()'s. Feedback is welcome. A nice demo is included in the comments you can try it out. https://github.com/adafruit/Adafruit_CircuitPython_PyPortal/pull/60

Does anyone have experience of CPB to CPB bluetooth range? 5m looks like max for me. Got them on their sides. One is LiPo powered.

do FDPLL0 and DPLL0 refer to the same pll?
under clock source selection it's DPLL0 and under PCHCTRLm it's FDPLL0
drowsy geyser
@slender iron Potentially dumb question. I'm looking at the CPB and I don't see any obvious pads to attach the J-Link. Any advice? I still need to ransack the lab to find it, but I'm trying to figure out next steps....
drowsy geyser
Oh!!! Got it. I was looking at one in a case and the pads are under the mounting hole.
Thanks!

@onyx hinge heya are you comfy testing the hardware side of the SPI simplex PR?
e.g. with scope/logic
onyx hinge
@meager fog I would need a suggestion of a "MISO" only device, I think
other than that, yeah
onyx hinge
that's true
meager fog
if so ill remove it from my todo list 🙂
onyx hinge
okay, so : pick a set of pins, verify that all 3 of: duplex, miso-only, and mosi-only work as expected.
meager fog
yep
onyx hinge
I didn't make headway on the audiomixer stuff yet, yesterday was working on a non-adafruit project and today I got distracted by urandom so far and now this 🙂
meager fog
np
onyx hinge
but I'm learning heaps about pi I/O from that so it might come in handy if you need a hand on blinka someday
meager fog
i do need a userspace-for-spi at some point
because spidev does not compile on constrained platforms 😦
we have pure python ioctl for i2c, but not spi
or do you mean bit-banging
onyx hinge
accessing the bcm28xx SPI registers directly via mmio
and it's GPL so you wouldn't want to directly pull it into permissively licensed stuff like blinka
meager fog
oh juk
yeah we prefer not to do that, because the offsets change with ever new pi
thus, we use python and spidev
we tend to write large buffers over spi at a time
so its ok
onyx hinge
which blinka device is so resource constrained it doesn't have spidev?
onyx hinge
oh yeah are those the tiny mips ones?
meager fog
yeppres
onyx hinge
spidev is all ioctls, should be doable direct from python without a compiled module. I can look into it someday, did that for linuxcnc too
meager fog
yah in the future, its not a huge rush
onyx hinge
kk
meager fog
as mentioned, we have it for i2c
and we only bumped into the one board that doesnt support it
the nice thing is its a very simple interface for SPI
onyx hinge
ok, stm32 feather is on the workbench 🥽
meager fog
ok in a vidmeetin 🙂
ill add ya to a new issue just so we have it down
ok made https://github.com/adafruit/Adafruit_Python_PureIO/issues/11 its not a todo yet - its just like, a note to remind us
@gilded cradle FYI ^

Excellent. Thanks @onyx hinge

<@&356864093652516868> I'm going to grab lunch and groceries. Will do Beta 3 once I'm back so please get everything in that you want to go out.

Quick, Scott is away, merge everything!

@slender iron the stm32f405 will still not have the MICROPY_CPYTHON_COMPAT enabled but I don't think it's worth holding up beta3 for.
AFIK this only impacts using the miniMQTT library at this time.

that's a reference that just went way over my head 😅

not a reference, just nonsense 🙃
pretty sure you could run a laundromat full of 1984 maytag washing machines with a trinket m0, if they're even electric. Pretty sure they ran on coal back then

I bought a Maytag washer in 1979 -- pretty sure it did not have have a webserver built in....

@solar whale "pretty sure" 😄

@solar whale is there a PR for it?

@ionic elk is working on it , but It is not ready yet.

I put a question about exception handling and recovery for adafruit_ble transient connectivity issues in https://forums.adafruit.com/viewtopic.php?f=60&t=160711 as I thought the answer might benefit others.

@simple pulsar: @idle owl has an example of a lot of exception catching for BLE; I'm looking for it right now.

tulip sleet
@idle owl thanks!
@simple pulsar I have ideas for writing a simple "EZ BLE" library that will handle all this dropping and reconnecting automatically; just haven't had time yet.
@simple pulsar see the send_packet() routine in that link
slender iron
ah, she beat me to it 🙂

Did https://github.com/adafruit/circuitpython/issues/2341 get done?
@idle owl @tulip sleet Thanks, will have a look in an hour or two.
onyx hinge
@slender iron I know I have some PRs baking, but let's let them go for beta3 rather than rushing to accept any of them.
I missed it anyway I guess
furiously scrolls to the present

yup, 🙂
onyx hinge
thanks for beta3!
slender iron
lots to go in beta.4 🙂
harsh matrix
Can anyone help me find docs for CircuitPython builtin libraries?
harsh matrix
I have very low expectation of finding help() via REPL
Oh, I can re-use those low expectations for the very easy to find documentation I was looking for https://circuitpython.readthedocs.io/en/latest/shared-bindings/usb_hid/__init__.html
I'm rehabbing an old joystick with obsolete interfaces, and I need to take some liberties with the usb_hid device provided by CircuitPython. I'm not sure how to define usb_hid device parameters in code, and I need to see some examples or documentation.
harsh matrix
OK. Thanks. That explains a lot.
slender iron
it is tricky with USB because the USB descriptor is used by CircuitPython itself
with BLE the HID descriptor is separated
idle owl
@onyx hinge Feel free to merge the PR you approved. Under normal circumstances I would also ask that you release the lib, but there's about to be a release sweep so you can hold off on that.
onyx hinge
@idle owl I will try to remember that. will also need a small tutorial the first time I do a library release!
orchid basinBOT
idle owl
@onyx hinge Ooh. Let's do a release on that library then to have you do it so you've got one under your belt.
onyx hinge
@idle owl we can do that right now if you want. is there a doc pointer I can start with, and then come back if I have a question?

@gilded cradle https://www.nxp.com/design/development-boards/i.mx-evaluation-and-development-boards/i.mx-rt1010-evaluation-kit:MIMXRT1010-EVK but probably the images are not licensed for re-use
slender iron
I bet @meager fog has an RT1010-EVK at adafruit they could photo
idle owl
Excellent. And, not really. I will think of a place to put that since this isn't the first I've needed to and won't be the last time I need to explain it. For now, I will explain it to you. It's quite simple. We have a basic template we include no matter what: ```
To use in CircuitPython, simply install the Adafruit CircuitPython bundle.
To use in CPython, pip3 install adafruit-circuitpython-bitmap-font.
Read the docs for info on how to use it.```Beyond that, you want to view the commit logs and mention any major updates above the template. In this case, we migrated to GitHub Actions and "Handle string inputs to load_glyphs for BDF." I like to thank the people involved with any contributions by @-ing them with their GitHub IDs as well, especially if they're new or don't contribute often. Use Markdown to format the list of updates as bullet points if you like, or list them however you like. The title should try to reflect the changes succinctly, but that's not always possible, so you can explain further in the release notes. As for the version number: do you understand semantic versioning?
onyx hinge
@idle owl so am I starting at https://github.com/adafruit/Adafruit_CircuitPython_Bitmap_Font/releases "draft a new release"?
idle owl
@onyx hinge Correct, exactly.
Take note of the current version number so you can choose a new one.
At least half the time I have to go back to find it because I forget to do that 😄
pastel panther
@idle owl I usually keep the releases page open in another window for that reason
pastel panther

just don't do like I did when releasing several libs and forget to close the releases window for a lib and the "recycle it" for another lib 🤦♀️

idle owl
@onyx hinge Great! Flip the order though, put the bullets above the template.
onyx hinge
okie
idle owl
Then publish release!
@onyx hinge Ooh wait, the URL for the library bundle is wrong.
You can edit it if you already published it
should be https://circuitpython.org/libraries
idle owl
We've been slowly updating them as we do new releases.
onyx hinge
I also added
Thanks to contributors @slender iron and @dherrada.
idle owl
Excellent!
idle owl
review again, send another link, it apparently changes when you make changes
idle owl
I refreshed and it 404'd 🙂
onyx hinge
interesssting
onyx hinge
so some time after I do this, it will be picked up and actually put in the bundle?
idle owl
Yes.
onyx hinge
that happens daily or so?
idle owl
The next time the bundle builds which will be tomorrow.
It builds daily when there are updated releases.
@onyx hinge Thanks!
onyx hinge
thank you!
hm the title of the release is a bit silly ("1.0.4: Merge pull request #15 from tannewt/load_string_glyphs")
should I specify a "release title" manually?
@idle owl
idle owl
@onyx hinge Ah yeah, sorry I wasn't clear about that. You should manually make a release title.
Something like "GitHub Actions and load_glyphs" or some such
meager fog
yes
onyx hinge
(I bet most users have no idea about actions vs travis, it doesn't make any difference a user can notice does it?)
