Oops. I was over at the Maker Garage (Microsoft's maker space) tonight. I was working on CircuitPython guides and one of the Makers asked what I was doing. I explained what CircuitPython is. He took interest and sat down. I was showing him the boards I'm working with and he was fascinated with the CircuitPlayground Express. He was like a little kid, looking at all the sensors and NeoPixels. So I gave it to him. Then I got home and found out that may have been my only unintegrated CPX. So I can either tear something apart or get a few more boards. I prefer the latter, but it's out of stock. sigh Oh well. I got "volunteered" to speak for an hour about Adafruit and CircuitPython, which is cool. So now I need to write a presentation and line up my boards to demo live!
stuck elbow
@drowsy geyser that is awesome, shame about the last board though
drowsy geyser
It's ok. When they make more I'll order a few and all will be good again. π
stuck elbow
it's weird that it's out of stock though, since they now add it to orders...
drowsy geyser
Oh hey, I'll be getting another one with my subscription to Maker: Space magazine. I'll have to go check my mail.
And who knows how many I'll find if I finish cleaning and organizing the lab. Maybe I'll do that this weekend.
stuck elbow
hehe, like pennies in the couch
drowsy geyser
LOL, yes, like that!
prime flower
since I'm traveling later, got to dig out the traveling with electronics guide (https://grathio.com/2012/04/flying-with-homemade-electronics/) to refresh my memory.
finding devboards and random wires in my backpack was "like pennies in the couch"
pastel panther
@drowsy geyser What do you mean by "unintegrated" CPX?
stuck elbow
not in an existing project
pastel panther
ah yes,of course
drowsy geyser
Yep, that's it. Like one of the is soldered into my arc reactor project, for example.
pastel panther
@stuck elbow Did you use any existing art assets to create your blinka board or did you do the whole thing in fritzing?
stuck elbow
@pastel panther I traced the logo from adafruit's website in Inkscape, and prepared all the graphics layers in that program too, then imported it into Fritzing
now I have a vector logo, though, so it will be better quality
pastel panther
Have you thought about making a blinka badge? With all this "badge life" talk I thought it would be a fun idea to advertise CP at cons
I was thinking you could have her belly scales be cap touch responsive
stuck elbow
yeah, sure, but it would need to be larger, to include the battery
also, that's kinda low priority atm
pastel panther
I think badges are generally around 70x140mmish
Would you be willing to share the artwork?
I have no idea if/when I could/would work on it but it sounds like fun
drowsy geyser
I need to send a note to support about getting SVG Adafruit logo files. I want to make someone a present with the laser cutter.... π
pastel panther
That would be cool
stuck elbow
This is already split into layers. You should be able to use it with whatever program you like for PCBs.
It's also cleaned up as much as practical
pastel panther
π
slender iron
@drowsy geyser I have spare CPXes if you need another soon
drowsy geyser
Thanks, @slender iron! They just got restocked, so I'll have another set on Wednesday - some to use and a couple to give away in the Maker Garage. π BTW, laser training is completed successfully, so if you need acrylic objects created, just let me know.
slender iron
@drowsy geyser ok perfect. π I just ordered parts for a shruthi (synth) filter and will probably just use a feather and circuitpython to generate the inputs
drowsy geyser
Oh cool!
slender iron
I was thinking it'd be neat to have a module control panel system
drowsy geyser
Oooh, that would be neat. Collin would approve. π
pastel panther
@slender iron are you making one of these?
https://cs80-com.myshopify.com/products/cs80-filter-board-for-shruthi-synthesizer
slender iron
I did the classic one: https://mutable-instruments.net/archive/shruthi/build/smr4mkii/
drowsy geyser
@slender iron I know you may not have an answer for this, but is there a targeted release data for 3.0? I'm trying to schedule a talk in the Maker Garage about Adafruit and CircuitPython and was wondering if I could time it to coincide with new software/hardware releases....
drowsy geyser
LOL! Ok. (That's the answer I give my kids when they ask how long they should cook something. "Till it's done.")
slender iron
π M4 board releases aren't blocked on it
pastel panther
That's cool; I was wondering about that
drowsy geyser
Oh cool. So it's just production scheduling - I heard a rumor the chips are available.
slender iron
if either of you have time for a quick review you could help me fix the build: https://github.com/adafruit/Adafruit_CircuitPython_Register/pull/13
@drowsy geyser we're still fiddling with the pinout
drowsy geyser
Ah, ok.
slender iron
we want to support as much stuff as we can
drowsy geyser
Totally understand. I'm not nagging, just collecting information. I'll schedule the talk and fortuitous timing will just be icing on the cake.
pastel panther
I can take a look in about 15
drowsy geyser
Good point!
slender iron
its because we need the audio stuff to get into beta
and dma is nice to have but not critical
(for qspi)
I'll check it in commented out if you want to poke at it @pastel panther
pastel panther
Ok cool
slender iron
hopefully you can figure it out for me π
pastel panther
Lol,suuuuuuuuure, I bet I'll figure it out in no time π
raven canopy
@pastel panther you going to review? i just jumped on and catching up...
aww man...that was my change. see, i'm really good at breaking stuff.
idle owl
@slender iron reviewed and merged.
raven canopy
well, in usual fashion. kattni gets it done just as i'm starting to look.
lol. page blinked, and i was like "merged? huh?"
π
idle owl
Restarted the build on my PR. Waiting on that now.
pastel panther
@idle owl! Leave some for the rest of us!
j/k π
idle owl
π
I mean I'm totally ok with that... π
Passed!
@raven canopy https://github.com/adafruit/circuitpython/pull/661 Can you approve or request further changes?
raven canopy
can do!
raven canopy
@idle owl approved!
slender iron
thanks for the review sommersoft
idle owl
Thanks for the merge!
slender iron
np
raven canopy
thanks for the doc fix!
pastel panther
Thanks for all the thanks!
idle owl
you're so welcome! π
Oh. Was busio how we controlled DotStars before we did up the DotStar lib?
pastel panther
Not sure? It's certainly how the status dotstar was working. I'm assuming the dotstar lib has more features since it's not trying to fit in the main CP code
idle owl
I'm updating some guide code and was confused momentarily about the fact that there was no dotstar import until I remembered that it was written pre dotstar-lib. And it seems to use busio. So I asked.
pastel panther
I've been meaning to read the code that does all the animations for error stuff because it's obviously not blocking so it must have some update routine that gets checked periodically
raven canopy
i've seen it...just can't remember where exactly off the top 'o my head.
slender iron
@idle owl yeah busio
idle owl
Thanks
slender iron
@pastel panther @raven canopy https://github.com/adafruit/circuitpython/blob/master/supervisor/shared/rgb_led_status.c#L204
pastel panther
haha, I probably glanced over it more than a few times as I was communing with the top half of that file
idle owl
Is there a reason we don't have board.DOTSTAR on the boards with dotstars?
Is it the nature of DotStars vs NeoPixels that it can't be narrowed to one label?
slender iron
right
idle owl
oh ok
slender iron
since its two pins
idle owl
Ok. Wanted to make sure there wasn't code magic that could change that. And also that I wasn't missing something.
buoyant wigeon
Hi developers, I search for help.
I have received 2 pcs Trinket_m0 from a friend from US, it's a nice and inspiring piece. Recently I have also contributed to campaign INDIEGOGO and few days ago I received 5 pcs of Exen Mini (https://www.indiegogo.com/projects/exen-mini-smallest-32bit-arduino-comp-dev-board-diy#/).
I got an idea to port CP to this piece as itΒ΄s the same microcontroller, SAMD21G18A. I did git clone CP and uf2-samd21 and successfully build bootloader and CP. Somehow it works, IΒ΄ve tried several small programs in CP but one thing worries me... if I do tap reset twice, I canΒ΄t get back to bootloader... itΒ΄s smooth with Trinket_m0, I can try 100 times without any problems.
Probably I miss some information, knowledge to build the bootloader correctly. Can someone please help?
PS: Your work is perfect, same with documentation. ItΒ΄s not a problem that IΒ΄m on the other side of the Earth (Czech Republic), I always find what I need on your web pages. Thanks.
pastel panther
So you were able to get CP loaded and working? The CIRCUITPY drive shows up? But you're saying the bootloader won't go into bootloader mode?
Did you base your uf2/bootloader build off of the trinket files?
buoyant wigeon
Yes, CP is working like you say but if I tap 2x reset I am not able to "jump" to bootloader...
... CP drive shows up and I can move *.py files there...
... bootloader and CP built from Zero... I have changed only LED pin to PA06 in bottloader (board_config.h)...
pastel panther
But it worked once for you to load CP?
buoyant wigeon
CP works all the time... I cannot simply recall bootloader by 2x tap the reset button.... CP drive stays for all the time unchaged om the same COM...
... yes, bootloader worked one time after flash and never again...
raven canopy
@buoyant wigeon CP drive stays for all the time unchaged om the same COM...
does a single tap reset the board? it sounds like reset.c is at minimum not recognizing the DBL_TAP_MAGIC value.
https://github.com/adafruit/circuitpython/blob/f00d2814b78e092656a05cb16674c37f6587b062/ports/atmel-samd/reset.c#L37
buoyant wigeon
if I do single tap reset the board get stuck ....I have to unplug microUSB cable and plug back... and CP is working again...
pastel panther
a single tap should just reset the board. If you're connected to the REPL with screen, sometimes it can leave your terminal in a unusable state if the connection drops
buoyant wigeon
yes, my small test program does some prints and after single tap the output is stopped...
CP is working ...
slender iron
@buoyant wigeon thats awesome! Feel free to contribute a board definition for it by making a pull request
raven canopy
@buoyant wigeon the only thing I can think of (which is why i wondered what single tap did) is that the reset button isn't acting exactly how it would on a zero. do you have any documentation on the whole pin setup?
buoyant wigeon
π I am amateur... if it is not ironic?
raven canopy
and there are people here that would be much better than I at helping with that further...
and we love amateurs (well, i do, since i'm one) π
idle owl
@raven canopy Is that everything from issue #566 ?
buoyant wigeon
It is sad I have asked Nerdonic for schematic but he answered "Hi Frantisek, unfortunately we are not giving away the schematic and PCB design for the Exen Mini, but we plan to in the future.
Kind Regards,"
raven canopy
@idle owl as mentioned in the task list, still need to go back and add the Travis badges for quite a few. avoidance is what i'll admit to; needed a doc break. I could most likely knock them out this weekend.
idle owl
Oh no worries!! I realised I had gotten through them and wasn't sure where that left the issue. Take the break!
raven canopy
most of the "work" will be git'ing. π
idle owl
Seems like it always is π
raven canopy
the temptation to script it all is there...but it's a one-off, so would likely take more time/energy than its worth. π
slender iron
@buoyant wigeon it can't be that complicated since its so small
@stuck elbow is gamepad working in 3.x? it looks like its reset method isn't called
buoyant wigeon
@slender iron I think so.... but I do not know where to go now ... I have to think also about HW.
I hoped that you have "some hidden SW hack" why I am not able to build OK bootloader...
so bootloader is probably OK... also webUSB is working...
slender iron
@buoyant wigeon I don't think the bootloader issue is due to circuitpython
where did you get the uf2 source?
buoyant wigeon
here ... https://github.com/adafruit/uf2-samd21 ... at your place
buoyant wigeon
@slender iron I have one question before the midnight here ... if I built the bootloader today I got a bootloader with this name "bootloader-zero-v1.26.0-adafruit.0-dirty.bin" ... why is there the appendix "dirty"? The results of the build were sooner without a word "dirty". Does it mean something "not allowed" or "any warning"?
idle owl
@buoyant wigeon I don't know the details, but it's not a warning. I know we've worked with many builds containing that appendix. I believe it has to do with changes made to the build that aren't part of the final build. But like I said, I'm not certain.
@buoyant wigeon Someone else will know better than me, and I'm sure they'll get back to you later, so check back in the morning. But know that it's perfectly fine to work with a ...dirty.bin build.
buoyant wigeon
@idle owl Thanks, I'll sleep more relaxed π
idle owl
@buoyant wigeon π Have a lovely sleep!
stuck elbow
@slender iron its not. it works when created from the repl, but crashes when created from code, and I didn't have time to debug it
I didn't even report a bug as I planned, because I didn't test it properly
slender iron
@buoyant wigeon "dirty" is a term used to indicate changes have been made locally since the last commit
idle owl
Ooh I was essentially right.
slender iron
yup
stuck elbow
@slender iron is this blocking anything? I'm hoping I will have some time this weekend to debug it.
raven canopy
@slender iron for expanding supervisor to nRF, should I add some handling for set_rgb_... , since the LED isn't currently on the board? if you currently set it, it acts like everything is fine... i can have it return something, or raise a NotImplemented.
I guess the same would go for the [dis/en]able_reload...
raven canopy
which is the same as just leaving it as is? the common-hal doesn't handle them..
just food for thought. i know you're heads down, so don't break away for this.
slender iron
its fine if it silently fails
someone will tell us it doesn't work if they care
/ we'll fix it up as we refine it
slender iron
π
idle owl
nice!
raven canopy
alright. π done! time to slice. then a movie..i think. pre-teens can be fickle. π

oh esp8266, you little oddball. π€
tribal pecan
yea I don't if the right place or not but still gonna ask
so the concept of Deep learning and machine learning intrigues me
as a Mechanical Engineering student I can see so many places that it can be used
but I have no clue on how to " GIT GUD " at it
so my question is
from where should I start ?
ps: should I install ubuntu in pc or windows is fine for a beginner like me
pastel panther
This is probably better suited for maybe general or project help, however I have a few resources I can point you to. One minute while I find them in my bookmarks
@tribal pecan I @mentioned you in #help-with-projects with a bunch of links to check out
raven canopy
i just dug farther into the esp-nonos-sdk than i ever wanted. i can now proclaim, i'm still lost. π΅
the naming conventions (which carried over into micropython [understandbly so]) are....bizarre? hehe
pastel panther
A wise man one said "being lost is the first step to understanding"
that man was me, just now
π
raven canopy
well, i just read someone's "esp uart journey", and I think my "lost" was actually a state of "can't be done". π
humble mural
Good morning everyone. What is the board the functions with BLE and CP?
pastel panther
There is budding support for the feather nrf52 on the 3.0/master branch but it's not really ready for regular use yet
manic glacierBOT
pastel panther
@humble mural I think however that there are some ble breakouts that might be useable with CP
humble mural
@pastel panther Thanks, I am running through several of the guides in Adafruit and I am having trouble using Wifi options. Our schools has many restrictions and firewall and they really don't allow stuff to talk to each other.
pastel panther
speaks UART which the feather m0 express, metro m0 express and likely others should be able to speak, however I don't know of any guides that would talk specifically about using them together
@humble mural are you just looking to do wireless stuff or do you have specific goals like talking to a computer/phone/internet?
humble mural
In short, I am an building a 2-3 year curriculum that includes as many uses and applications for "IoT" type of devices. I like BLE becasue we can run that in the classroom with no issue.
I'll start the kids on the CPX, then move up and on from there.
So I am doing a lot of the guides at home so that I can determine what works and doesn't work in the classroom setting.
Overtime, I would like to develop lesson plans tied in to nation standard that we can share.
pastel panther
this might be useful for working with the aforementioned nrf8001 breakout: https://learn.adafruit.com/adafruit-gemma-m0/circuitpython-uart-serial
humble mural
@pastel panther After all that I would like to control NeoPixels, servos etc, wirelessly.
pastel panther
Can I ask why IOT? not that it isn't a decent theme to organize this type of learning around
right
raven canopy
@humble mural esp8266 can act as both a station and an access point...
stuck elbow
even at the same time
raven canopy
yep
stuck elbow
that's better than my laptop
humble mural
@pastel panther Not married to the term, just a term that I can use in discussion with school personnel and they will have a concept of what we are doing.
@raven canopy for wifi only correct
pastel panther
it's probably really good for that purpose as most admins might have heard of it but probably have never heard of "embedded"
raven canopy
yes, wifi only. but, just wanted to make sure that you knew that 2 esp boards can talk to each other.
pastel panther
it seems the people who know what they're talking about have awaken so I'll defer to them
raven canopy
says the guy working on M4 core stuff... π
stuck elbow
I only look like I know what I'm talking about, honest
raven canopy
mimics deshipu
humble mural
@pastel panther Let me give you a quick run down of where we are at, I teach programming (high school level) and we are experiencing high level of burnout (basically kids get bored of coding in front of a computer for three years). I was brought in to change the program, keep the programming roots but infuse other skill that will make the student better prepared for college.
raven canopy
brb. time for coffee cup #2... β
pastel panther
@raven canopy that's a great idae
humble mural
we also have to compete for students with other schools, we are a 100% magnet school, if kids don't apply, we don't have students, so the program has to have a marketing edge to it.
In searching for a name for what we do, we came up with the (IoT Strand of the Acadamy of Information Technology)
raven canopy
well, with that in mind, i can see the draw to BT/BLE. Then you can marry the programming side to something they absolutely love: their cellphone. π
humble mural
@raven canopy BTW, I had no idea two ESP8266 could talk to each other, that is a game changer for me,. I'd buy you that second cup of coffee just for that bit of news.
Bingo!!
stuck elbow
I think an esp8266 working in AP mode can accept connections from up to four other devices
so there are limitations
humble mural
People think they understand IoT, I feel embedded (though more accurate) would make parents think that we are sticking there kids somewhere) like embedded reported in the military etc.
how do I type the first character of your name beshipu so Discord picks it up?
pastel panther
the idea that you should be chasing students at a magnet school is crazy to me
but that's beside the point
raven canopy
the esp would allow you to construct a "how do we" scenario. but like you said, that's all in front of a computer screen. the off the shelf BLE apps will only do so much (that i know of; haven't messed with it myself), so look into that set of limitations too. 
nRF is young, but it is functioning on a basic level.
pastel panther
I should really get 3.0 on my nrf52. I just want to figure out how to get mynewt back on before I wipe it
humble mural
@pastel panther It is nuts, we have some schools (regular public schools) that have enrollement issues becasue of violence, school grade etc. The district has set up very appealing (all marketing) programs at these schools to draw students to stay at their home school. People want to come to our school because rankly, it's paradise, but we are losing kids the other public schools because of the glitzy programs they offer.
pastel panther
Thats crazy
humble mural
We have to offer programs on the down low. We have students visit our school and they see what we dow but the actual program can't appear on a Magnet Application.
pastel panther
It's been a while since I was in HS but I was fortunate enough to get into the locala magnet school, but people were beating the door down
say that again
?
humble mural
@raven canopy left me finishi this thought, I'll catch up
raven canopy
π i'm going to get back to documentation work; i'll be bouncing in and out of discord.
humble mural
@pastel panther so My prinicpal wants the kids programming, making bluetooth helmets, programming neopixels, 3d printing case for the stuff they make so that when kids walk in to my room with their parents they are blown away. Trust me no one is doint this in our county, This will be the frist true "Maker" program in our district, just can;t call it maker because most parents just don't know. We are a title 1 school
humble mural
@raven canopy I just read your comments a bit over my head. can you post a link to a guide that explains (provides an example). I have about three ESP8266 in my bookbag, I can test it out today.
@pastel panther me too, hate politics love working with kids!
thanks
raven canopy
@humble mural that last comment was kind of a mash of two topics. let me expound a little.
- using the esp8266, I was thinking that using them to communicate with each other for a targeted reason (esp1 detects a button push, tells esp2 to turn on an LED) would allow you to construct a "how can we make this work scenario". obviously you'd have to start with explaining capabilities in a way that doesn't exactly make the desired end goal blatantly apparent.
- The Bluetooth apps that are available to work with the nrf52 boards do have some limitations as to what they can do. As far as I know of, at least. here is a list/info on the apps: https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/software-resources
humble mural
- I understand the concept, no guide for that, or do I Google that one?
- I will look at that guide today, though I don't think I have an BLE board in my bookbag
Also, this is all for CP?
raven canopy
i don't recall Adafruit having a learn guide on having two esp8266s communicate. but, there are plenty of examples in "the wild" of having the esp8266 handle incoming requests (mostly Arduino).
the nRF resources for CP are pretty non-existent at this point; still young and all. once it's officially supported, they'll start flowing.
raven canopy
maybe? my knowledge of micropython comes mostly from circuitpython. i don't spend much time on that side of the tracks. π
raven canopy
π½ enjoy!
pastel panther
hey @slender iron I pulled master again, updated my board files and got QSPI working on my m4 board, wew!
aaaaaad he runs away
slender iron
nice @pastel panther ! now you should get dma working π
(had to feed hungry kitties)
pastel panther
haha, sure. I'll take a look. Does the code show well enough what wasn't working or can you give me some clues?
slender iron
I was ussing the saleae to watch it
I'd get two sets of four (maybe eight) clocks to read data in but then it'd stop
the code would hang waiting for the dma transfer to complete
pastel panther
hmm, ok
I was able to make some sense of the traffic with the normal SPI plugin, however I found a third party QSPI analyzer. Couldn't get it to compile though
slender iron
the spi one works just fine because the command and address look the same
the data just won't make sense
pastel panther
right; I was slowly training myself to recognize the commands. The one I found can decode the commands as well (it seems from the code)
bbiab, running to frys
raven canopy
ok. the PR emails should slow to a trickle now.. π
@slender iron subtract 42 from the PR numbers for the meeting; today was cleanup for missing Travis badges on most of the docs. rework doesn't count!
manic glacierBOT
raven canopy
@slender iron what is the [desired] RTD path for cookiecutter? going to work on the conf.py (both actually) before i get this library started. Also going to put some Windows "warnings" in based on my experience. π
slender iron
you mean url?
raven canopy
yeah
raven canopy
hmm. i might have to explore using WSL Ubuntu...

@slender iron can you point me to that plugin?

might make things like cookiecutter a little easier.

@drowsy geyser cpx back in stock.
drowsy geyser
@timber mango Yep. My bag full of them arrives Tuesday. π
timber mango
I messed up one of my three (somehow) but it's functional enough to keep using it. The other two are awesome.
drowsy geyser
I ordered extras since I'm giving a talk at about CircuitPython for the Microsoft makerspace. I'll have some extras to give away. π
timber mango
Yeah on my TODO list is to obtain a few boxed sets (it's a 5 dollar upcharge) to hand out.
drowsy geyser
People go nuts when you just h and them hardware and say, "here, these are awesome!"
timber mango
I gave the nephews a variety at xmas time; cpx, trinket m0, feather m0 express and maybe something else or a duplicate. Figured they'd fry at least one and hoped they'd not fry the CPX right away. ;)
drowsy geyser
LOL! How'd it work out?
timber mango
They are lost boys (now men in their early 20's) and do not speak except in their basement/dungeon areas to other friends. Surprisingly, quite verbal when stuck in a car with them on family errand. So not one word. ;)
drowsy geyser
π
timber mango
They're all hooked up to internet and are in college so I don't worry too much.
We went out and did mischief with our cousins (outdoors) at family gatherings. these two bow their heads and pray to handheld devices. Six of one, half dozen of the other.
drowsy geyser
I hear you. Conversely, I gave a CPX to a friend, who handed it to his 11 yo son and said, "go make a burglar alarm". Kid loaded up MakeCode and about five minutes later brought it back. You turn it on and if the accelerometer detects movement it beeps and flashes the lights. My friend was impressed with his kid. π
raven canopy
is that how Tested got a hold of one?
timber mango
That's pretty good. I wonder if there was some existing knowledge in the son the friend was previously unaware of.
My niece was 2-3 yrs old and in the grocery with her mother (long ago). She conversed fluently in spanish with the produce guy. Her mother was completely unaware the girl had acquired a second language (from someone they employed about the house).
drowsy geyser
That's awesome!!!
timber mango
Her brother is now fluent in Mandarin and has had an interest in it since age 9 or so (he's mid 20s now and in a formal training program in Mandarin).
drowsy geyser
I envy people with language and artistic skill. Since I have none....
raven canopy
that is pretty awesome. i've tried to push a second (and his mother's native) on my kid...not successful.
timber mango
My mother was fluent in Polish when I was a child; with nobody to speak it to/with, she lost the skills. Her grandmother spoke no English (at all).
drowsy geyser
Same with my grandmother and her grandmother (only it was German, not Polish).
timber mango
I just try to tell any young people to try to preserve whatever they've got in cultural heritage. In the name of assimilation our family lost a lot of ground.
raven canopy
the downside to being a herding animal...
drowsy geyser
Agree. Mine is the same way. Though genome sequencing and ancestry.com have done a lot for preserving/exploring the family tree. My family's ancestors for example, came over on the Mayflower.
timber mango
Ellis Island also took away our proper names (Irish and Polish names). I think. Don't know the conventions in names to be sure. Then one great (xn) uncle decided to change the spelling of our branch of the family's name, because he was tired of getting his brothers ground mail deliveries by mistake. ;)
Alright I'm not #circuitpython-dev even a little, here. ;)

True, we've wander just a TAD off topic. π
timber mango
I'll put what I think about this in #general-chat, after watching it a bit so I don't just splashdown, there. ;)

@pastel panther I saw your note about being lost... Davey Crocket was once asked if he'd ever been lost. He replied "Lost, no, but I've been bewildered for a few days at a time, on occasion. So I guess he knew quite a bit. :^)

I usually start off with a destination in mind, but some times there are unforeseen forks in the road, with no route signs. When I entered college I never dreamed/imagined the job I'd retire from many years later. As the say, when life gives you lemons, make lemonade. So, it is all about the journey.

@slender iron @tulip sleet for Monday .. Does CircuitPython support i2c clock frequency setting by the end-user in a friendly way? Is the default frequency modest enough to ensure good communication with a low skill level of circuit implementation?

Speaking of issues, I found a bug in either simpleio or CircuitPython 3.0 Alpha 2 where PWM output works only intermittently (whilst testing @idle owl 's guide code). I opened an issue in the simpleio repo. Do I also need to open an issue in the CircuitPython repo and link the two together? I'm really not sure where the bug lies yet....

I opened an issue in the CircuitPython forum and tannewt and jerryn helped me. Now it's a couple weeks later and I continue with an issue using a DotStar 30/m white strip. I've reviewed the APA102 & 102C data sheets, read Tim's blog (cpldcpu), and I am mystified at what I'm seeing. I've got a sorta big write-up going with the latest DotStar library (1.1.4) and some empirical evidence regarding the End Frame size. Where would be the best place to post this?
umbral dagger
I received/built a MetroWing board form @pastel panther /OshPark. Going to revisit my dotstar wing game stuff on a MetroM4 with 3.0
umbral dagger
Hmmm.. except that it doesn't give me a CIRCUITPY drive. CP build from master. It's running, and REPL works fine. Just no CIRCUITPY drive.. although it sounds like it tries to mount & unmout (Ubuntu makes noises for those things)
stuck elbow
@umbral dagger is that the black metro m4?
@umbral dagger build the firmware for rev b board
@umbral dagger the new revision has flash connected differently
pastel panther
ya, @umbral dagger make sure you're using BOARD=metro_m4_express_revb
'twas changed with the addition of the rev D with qspi which should be close to the final board
stuck elbow
@pastel panther are you also adding qspi to your board?
pastel panther
already did. It's tested and working
I have a debugged board file if you're interested but I think I'm going to shrink and stretch it into a bitsy and feather
I think the bitsy will omit the SWD connector and qspi debug headers
stuck elbow
how about the oscillator?
pastel panther
@timber mango it's got a crystal but I'm not sure that 3.0 is using it yet so technically it's untested
I suppose I could write a simple clock setup but it's not at the top of my list
also "simple clock setup" on a samd = lol, right
stuck elbow
I'm asking, because ultimately I would like to make a bare minimum board for it, crystalless like the trinket
pastel panther
You certanly could you only need it if you use it. You could also omit the inductor for the voltage reg if you can make sure it only runs in linear mode
And you can also use the 2x3mm flash chip like is on the bitsy express
now that I look at it, the bitsy is also crystalless
You can also make it even more minimal if you don't need to have two simultaneous power sources which requires the two diodes, though there are some really, really small diodes out there
gotta run for now
umbral dagger
@stuck elbow @pastel panther That did it. Thanks
And... it's mounting readonly.

@pastel panther I know it's technically possible, I'm just afraid that I won't be able to figure out the correct settings

When I do a dir(board) I don't see SD_CS
slender iron
@stoic gazelle I think you'll need a different pin
stoic gazelle
Are there different ways to set the pins for the feather wing? I guess I thought it'd be a set thing

as long as you don't run into pin-smashing, should be good. but, code space might get a little tight?

is this the right chip? οΏΌ
stoic gazelle
yeah i'm going 1 step at a time, if i can only use 2 i'll do the data logger and the gps and then wire up 4 buttons
one button for each: stop, start, other side of road, my side of the road
i ran into issues with sd card and gps though so i'll have move on even though those are core to the project or if need be switch to arduino - still will need to make sure no pin smashing is going on
raven canopy
@solar whale that looks like the right chip. if i had to guess at least...
raven canopy
@stoic gazelle if you want to stay with circuitpython, and code space becomes tight, you could try and strip out non-essential functions from your libraries. thinking along the lines of, say, gps.speed (haven't dug into the lib...just an example). that'll save you space on imports.
@solar whale seems yours is the same one on the product page pictures.

import sys is foe something else - not needed.

@raven canopy thanks for the quick responce! well after the loader was flashed it only appears as "itsyboot" when plugged in. i dragged the .uf2 for the itsybitsy onto it after remebering where to find cir-py updates: here: https://github.com/adafruit/circuitpython/releases/tag/2.2.4 this seems to have fixed the issue
however
i am curious if i can make my own .uf2 version so I can add my own pin names and other things etc any tips? and @raven canopy thanks for putting it in #hug-reports

@solar whale currently 2.2.4
solar whale
trying it first with 3.0 since taht is waht I have installed.
stoic gazelle
i'm okay with upgrading if that helps, it'd be nice to not have to modify the hardware just yet if possible
is there a different library bundle for 3.0?
raven canopy
@marble hornet it is possible. this guide, while outdated and refers to micropython, will get you setup with the toolchain to build your own firmware.

@stoic gazelle that was an adlogger featherwing on a feather M0 express with CP 3.0

@raven canopy im running osx but i have windows installed too, it just hasn't been setup. like no discord or even arduino ide just atmel studio. (unused atmel studio )

Teh version fo CP3.0 was a few weks old - I am updating to current master - just to check.
marble hornet
how does adafruit make thier .uf2 files w/ libraries included. like where the pin definitions for the board module are located? can they be customized? many thanks for all the help
raven canopy
for the VM, i recommend you stay with osx. as one of the very few windows guys here, it can be painful get it all working.
marble hornet
@raven canopy i was planning to stay with osx (im comfortable with it.) thanks for the tip though. i am unfamiliar with github, what is 2.x ?

@marble hornet here are the pin defs specific to the itsy. the MP_QSTR_XX is the name part. https://github.com/adafruit/circuitpython/blob/2.x/atmel-samd/boards/itsybitsy_m0/pins.c
and that link is to the 2.x branch. you'll need to setup a GitHub account to create a fork (copy) of circuitpython . GitHub actually has a very good set of tutorials to get you familiar with using the site.
solar whale
@stoic gazelle - confirmed taht is still works for me with CP3.0 master. Do you ahve anything else connected to the feather_m0_express?
stoic gazelle
i took off the gps and joy wings so no not any more
solar whale
If I rad things correctly, Error 19 is "No Such Device"
stoic gazelle
so possibly an sd card error?
solar whale
waht kind af card are you using?
stoic gazelle
it is a fat 32 16gb card
solar whale
brand
stoic gazelle
sandisk
stoic gazelle
I need to head to bed, I can try with cp 3.0 tomorrow and double checking the micro sdcard/trying other micro sdcards
thank you very much
solar whale
mine are only 4Gbyte - do you have anotehr card to try.
solar whale
OK -- good luck and good night!
raven canopy
good night @stoic gazelle .
@marble hornet i do recommend watching TonyD's youtube video on that page a couple times. helps to understand the process before diving in. took me like a week to get it all going (but...Windows π )
marble hornet
oh so each fork is a copy, regardless of selected branch!! ill be sure to look at that video when time comes.
@raven canopy last question (probs not but... i neeed sleep (just had a first robo-comp this weekend)): do you know what is used to create the .uf2 file? how it is synthesized?
raven canopy
yeah, a fork is the WHOLE repository, to include all of the branches.
solar whale
Off to bed as well - hope te power is still on in the morning.... Good night all!
pastel panther
night @solar whale
marble hornet
night @solar whale
raven canopy
@marble hornet I'm not exactly sure. i know that the .uf2 concept/format was developed by Microsoft...and it works. thats about it. π
marble hornet
or @pastel panther do you know how? (above)
raven canopy
marble hornet
@raven canopy thanks so much, ill start chewing away at cir-py more. stay safe!
raven canopy
again, you're welcome. there's a lot to chew on...i'm still in my early bites as well. π
marble hornet
** bytes ?
raven canopy
haha. correct, you are!
pastel panther
sorry, can you restate your question? You're trying to build a uf2?
@marble hornet If you're trying to build a uf2 on osx, you'll want to get the arm dev tools cask from brew
let me look up the exact name
brew cask install gcc-arm-embedded
slender iron
uf2 is a reformatted bin file
raven canopy
i pointed him to the Vagrant setup. but, if there's a better way...well, that's even better!
pastel panther
you'll obviously need to install homebrew if you don't have it
slender iron
osx + brew is my setup
raven canopy
is there a better guide for building firmware, than tony's micropython ones? (not for me...i know i'm stuck in VM land with windows)
pastel panther
@raven canopy not that I've seen but then again I didn't look hard
marble hornet
@pastel panther is the intall above good to go?
pastel panther
brew cask install gcc-arm-embedded is exactly what I used
slender iron
@raven canopy its still a good option, especially for windows
pastel panther
@raven canopy what version of windows? I've heard the linux subsystem for Windows 10 is actually pretty good
raven canopy
especially = essential (we don't enjoy make like everyone else)
@pastel panther i downloaded WSL Ubuntu the other day. I need to find out if folders can be shared...and USB. neither would in the little time i spent with it
and i read that only USB MSC passthrough is currently supported...which may or may not be all i need.
pastel panther
also CDC for the REPL?
raven canopy
yeah, CDC would be needed for REPL. but, i could still use the Windows native for that...
marble hornet
so a uf2 file is a bin with a different file ending?? I'am guessing in the dark here but is a .uf2 file where the python interpretter is? and the uf2 bootloader handles the magic block management and serial / usb appearance while the python runs "ontop".
pastel panther
@marble hornet Almost but not quite
marble hornet
done installing
pastel panther
what board are you trying to build for?
marble hornet
@pastel panther okay, i cloned my fork of cir-py to my local hardrive
i have an itsy bitsy m0 hooked up right now eventually i want to make my own board w/ a samd21g and another samd21e. im also using it mostly to make a tricorder.
pastel panther
@marble hornet actually your prior description of how uf2 works was pretty spot on with the caveat that the bootloader only sets up usb MSC for loading the uf2 file onto the board. After it's loaded CP (yes in the uf2 file) takes over and handles running the interpreter and setting up USB mass storage and serial for loading python files and communicating via the REPL
you'll want to go into <your_cp_dir>/ports/atmel-samd/
marble hornet
in terminal?
raven canopy
once it's done compiling, you'll have a folder build-itsy_bitsy_m0_express
and the firmware.uf2 will be in that folder.
marble hornet
its throwing a " Makefile:5: *** Invalid BOARD specified. Stop."
pastel panther
hmm..
marble hornet
okay
pastel panther
if you ls boards/ you should see a dir for it
marble hornet
so the folder w/ the config and etc is there but when i tell terminal to make the file ports/atmel-samd/build-itsybitsy_m0_express/ stays empty
pastel panther
oh I forgot
go into the root of your circuitpython checkout and type
git submodule update --recursive
marble hornet
pastel panther
There submodules are essentially references to other repos that your project/repo has included
it probably didn't build properly if you didn't get the submodules
raven canopy
hmm. it should error out if the submodules aren't there. well, it does for me...
marble hornet
root in this case means?
pastel panther
the lowest level directory of the checkout
raven canopy
that was not the error i was looking for
pastel panther
it should have the ports dir
pastel panther
when I say "lowest level" others mean "highest", fwiw
raven canopy
~/circuitpython/?
pastel panther
probably
unless you cloned it with an alternative name
sorry by checkout I meant clone
pastel panther
so it should be called 'circuitpython'
go into that dir and run the git submodule update --recursive
marble hornet
i have circuitpython in the .git dir shown here. when you say root does that mean i should navigate into cirpy?
just saw your message, trying....
run
navigating back to port
still not making the uf2 file. @pastel panther THANK you for all the help. if you want to head to bad i'm fine with waiting till tomorrow
pastel panther
I'm up doing stuff so I'm happy to help but I can't tell if you're doing everything precisely correct
I'll write a list of steps that you should follow explicitly and it should work
marble hornet
okay, want to take it slower?
marble hornet
im going to exit and restart terminal. take all the time you need
pastel panther
make a local copy of circuitpython by cloning it:
git clone https://github.com/adafruit/circuitpython.git
stuff downloads
go into the directory that you just made:
cd circuitpython
update/fetch your submodules:
git submodule update --recursive
more stuff downloads
Once the submodules have successfully updated, move into the port directory for the SAMD chips:
cd ports/atmel-samd
build for the itsybitsy_m0_express:
make BOARD=itsybitsy_m0_express
If the build is successful you should see a message when its done saying that it created a firmware.uf2. If you don't see this, post or screenshot any errors you see
you can skip the first step if you're confidant you can get into the directory that was created as a result of your original git clone....
If after any step you see something that looks like an error, let us know
marble hornet
taking video of me typing in the commands
marble hornet
file is too large
i'm going to paste in the terminal if thats okay w/ you all. how do i make the code in the dark box?

do what @raven canopy said

ooh @raven canopy 's code did something
pastel panther
sorry, it's been forever since I did my checkouts

im going to try making again

it should work after the submodules update

yay
pastel panther
you can, but I never use it

its making a bunch of files

I probably should eventually

do you have python installed?

i do
pastel panther
do which python
pastel panther
try which python2
marble hornet
in term?
pastel panther
ya
marble hornet
where in term?
marble hornet
/usr/bin/python```do it with python2
marble hornet
Jonahs-MacBook-Pro:atmel-samd jonahy-m$```you probably need to install python2
pastel panther
ya, you should be able to install it with brew
marble hornet
does a .pkg not work?
raven canopy
line 370 of the Makefile: python2 $(TOP)/tools/uf2.........
raven canopy
all of the others are 3... uf2 might be written in 2. checking.
marble hornet
uhhhhh?
pastel panther
you're probably looking at the wrong Makefile
marble hornet
atmel samd?
pastel panther
should be circuitpython/tools/uf2/uf2tool/Makefile
marble hornet
oh
pastel panther
though hold up as sommersoft is checking if changing it will even work
marble hornet
um.....
raven canopy
no, i was talking about L#370 from atmel-samd/Makefile. though, i may have been on master not 2.x. at anyrate, the line points to uf2conv.py, which is written in python2. it'll fail with 3 (print statements without parens).
pastel panther
ok
so, long story short install python2?
I think I'm going to just keep my mouth shut for now...
marble hornet
ok so install 2 .pkg work? also where shoud the final file show up? thanks so much you two!!
raven canopy
lol. its a team effort!
the final file will be: circuitpython/ports/atmel-samd/build-itsybitsy_m0_express/firmware.uf2
raven canopy
no worries, man. getting the toolchain running is a task in itself. and usually only done once... (this was told to me when i was setting it all up; wise words)
at least you don't have to use the VM. that's an added layer. but, like all things, it becomes muscle memory.
raven canopy
i'm sure you could, but i don't think it'll work.
marble hornet
it didn't
raven canopy
there should be 3 firmware files: elf, bin, and uf2
raven canopy
woohooo π π
raven canopy
holy mother of....when did it turn 1AM? ugh..."they" stole an hour from me yesterday and haven't given back yet. π
pastel panther
just move to the best coast and you'll get 2 extra

alright, i'm out. @marble hornet welcome to the firmware builder's club!
