[timid plover]

so when you see the release notes that mention NimBLE - you just see "BLE" 🙂 ?

[dawn bear]

It is SUPER expensive to design your own SOC!!!

[timid plover]

a recent embedded.fm and The Builder Circle podcast - and they would agree - purchase off the shelf products - if they are avaiable

[cinder wind]

Would be kinda cool to have a Feather or QTPy that was actually an FPGA running some softcore

[dawn bear]

Nah Scott. You need to getting hardware threading in CP... right! I mean The future will probably be more cores? No? 😄

[cinder wind]

yeah PIO on RP2040 has been much more my speed, lately. nice bite-sized programmable logic

[wild urchin]

But The GIL!

[grand tusk]

My RP2040 system has six cores.

[timid plover]

please explain - PIO?

[grand tusk]

three pico cluster, with UART link.

[dawn bear]

Well I was sort of looking at JPs issue with display interfering with sound. Whereas if it could run the display code on a the other core while sythio was running on the other core. That might have mitigated the issue

[cinder wind]

this is what I do in Arduino on RP2040. core1 is all UI/MIDI, core0 is audio synthesis

[dawn bear]

Ok. Cool.

Or a GPU 🙂 - A whole nother ball of string! 😄

Is the core of CP modular?

Meaning like you can build a light version

[cinder wind]

PIO is a chunk of programmable logic in the RP2040, a hardware state machine that's very fast and made for implementing bus protocols like SPI, UART, I2C, even DVI video! CircuitPython uses it for protocols like I2S audio, Neopixels, and I think captouch sensing

[dawn bear]

Or a version with has framebuffer and another that doesn't

[timid plover]

thanks - Dexter clarified his cores

[cinder wind]

ahh got it, sorry

oh yeah right it's not. my "touchpio" library uses PIO

[timid plover]

looks like I need to learn to use the github tools to browse code better 🙂

[dawn bear]

Yeah. I use Intelli J so I can CMD-Click around 🙂

Light is getting dimmer in the window. 🌓

Very small suggestion and feel free to ignore it, but when streaming you font could be bigger. JMO

[timid plover]

is there any CI on the esp-idf distribution ? ( e.g. why don't they see the error you see? )

[dawn bear]

COOL! You found it! The plot thickens!

[timid plover]

they will add a test case after you submit an issue 🙂

[dawn bear]

Wonder if they have a Magic Smoke enabled test

OMG You just triggered Alexa looking up magic smoke

[timid plover]

how do you get ahead of the esp-idf?

[dawn bear]

That was some impressive git foo

The latest highend macbook pro

What you didnt want to spend $5000 on the Mac?

[grand tusk]

And then, Sonoma.

[timid plover]

I remember paying more for my gateway DX2-66 🙂

[shell mason]

not that customizable but kfocus have nice linux laptop

[timid plover]

https://ancientelectronics.wordpress.com/2018/11/06/gateway-2000-4dx2-66v-desktop/

you said less flash than rp2040 - did you mean less ram ? ( rp2040 zero flash, right? )

[grand tusk]

Using I2S with Qualia board.

[dawn bear]

Shouldn't you open a ticket to update 5.3... before launch?

[timid plover]

so how did you describe the ~~vimeo (sp) ~~extension ? ( vimium )

[rapid hornet]

vimium

[dawn bear]

Okay than I want you to write a OS in CP for my 3D printer. Today. Lets get started. Assume an STM chip. 🙂

[timid plover]

thanks for sharing the correct spelling and example of vimium !

[shell mason]

the vimeo is like yt what i know so just mixed up

[dawn bear]

I'll check it out!

[shell mason]

the laptop and thing the k-focus machines https://kfocus.org/spec/

[dawn bear]

Well I think that about wraps it up for me! Thank you @rapid hornet !!! It was interesting to see how you track down that build issue.

Very interesting!

HAve a great weekend.

[timid plover]

I wonder if there are others watching that are further north? ( I think sometimes we have others in the great white north

[dawn bear]

Best to your family in these hard times.

[cinder wind]

quick questions (lol): any good resources for debugging CircuitPython with a debugger? (does https://learn.adafruit.com/debugging-the-samd21-with-gdb still largely apply?) What are some good functions to break on?

yep cool. reset_into_safe_mode() Any tinyusb funcs or other USB functions useful when debugging USB enumeration issues?

yeah got a Beagle 🙂

perfect. already doing CONSOLE_UART...

thanks!

The problem is plugging CircuitPython device into a USB Host CircuitPython causes the device to panic

(the USB Host CircuitPython stays functioning)

hehe okay

[rapid hornet]

https://github.com/bnahill/PyCortexMDebug

[timid plover]

does that work with rp2040 too?

thanks - will look at rp2040.svd

[rapid hornet]

https://github.com/raspberrypi/pico-sdk/blob/master/src/rp2040/hardware_regs/rp2040.svd

[timid plover]

thanks scott - lots of support based on my adafruit order list 🙂

yes

[cinder wind]

thanks Scott!

[rapid hornet]

[smoky island]

I am getting started for the morning now, trying out the newest web workflow changes and working on refactoring in circup. You can follow along on Twitch: https://www.twitch.tv/foamyguy_twitch or YT: https://www.youtube.com/watch?v=npRzrXkywDo

[inner spade]

Good morning. ☕🧇

[clever summit]

Hey Tim! Todays project is to dive into making Sphinx document a Python library of mine.

Not sure Sphinx is the best bet though?

I tried the builtin one. Was not impressed. 🙂

Ha. Got this.
docstring of growcube_client.growcubeclient.GrowcubeClient.connect:3:Unexpected indentation.

Not sure why it would care. 🙂

Line 3 of the comment.

For the connect() method.

[unreal bay]

Only half following along so apologies if not relevant.
I've just setup a bundle (cloned community bundle modified for my own libs, then project and libs use pyproject.toml for circup bundle-add) and it works for usb. Would it also now support web workflow after this PR gets a bit further?

Nice, thanks for the contextual summary.
Bundle-add seemed easy once all finally tweaked.
https://adafruit-playground.com/u/tyeth/pages/creating-a-circuitpython-library-bundle-for-circup

Got an early preview after watching your stream

Yeah I only use --py

Huge

Interesting test. Shouldn't be too big, but I'll sort out some mpy support

Think os.fstat("/") or storage has a method

i use this, but it can be occasionally not 100% reliable for the final bytes, especially if a failed to close file + reboot happened

    def get_free_space():
        s = storage.getmount('/')
        return s.statvfs(0)[0] * s.statvfs(0)[3] 
        # consider 4 for non-priveleged free blocks
        # https://docs.circuitpython.org/en/latest/shared-bindings/os/index.html#os.statvfs

    def get_total_space():
        s = storage.getmount('/')
        return s.statvfs(0)[0] * s.statvfs(0)[2]

it's 100% as the OS knows.

The port should be okay, but pass required

No, that's code for Circuitpython

Are you using Mac, did the save of settings.toml get corrupted

[grand tusk]

Good morning all!

Tim's on Linux.

I'm enjoing circup-over-wifi.

Hay you should also add lipo battery support for the updated pyportal.

[open girder]

pyportals are getting redesigned to use S3 modules, no ETA but we'll add lipo for sure!

[tulip kestrel]

How did you come up with the name of your company?

[open girder]

limor goes by "ladyada" and happens to like fruit, so it end up being "adafruit" 🙂

[midnight plinth]

[dawn bear]

I understand the product - but not @haughty quiver's graphic. ❓

BTW: Hello from Los Angeles

👋

From the world I come from, CPUs don't feed displays directly. There is always a frame buffer that has some DMA channel feeding it. So this is interesting. Remember JPs workshop last week where updating the display caused distortion?

Heck even in my atari days (yes I am that old) there was a DMA chip. So microcontrollers feeding displays has alway been a new paradigm for me.

[ebon stratus]

Hello. Would anyone suggest a good group/forum to get suggestions to fixa problem I have. In Python, module BS4 (BeautifulSoup) is callable in terminal, but not found in VSCode, Thhonny, Mu? thanks

[drowsy inlet]

maybe try the #help-with-circuitpython group?

[waxen thistle]

Good afternoon all you most excellent people!

[drowsy inlet]

hello all

[sand lotus]

python is a bit different than circuit python. might try a more generic #help-with-projects

[inner spade]

Hello! 👋

[sand lotus]

Howdy!

[viral sail]

Good afternoon.

[ebon stratus]

This is Python however, not Circuit Python.

[open surge]

good afternoon!

[drowsy inlet]

yeah, i didn't see a channel specifically just for python when i suggested the circuitpython channel

[waxen thistle]

FYI, twitch is having some hiccups this afternoon. You might have a better experience on YouTube

[unreal bay]

Good evening, tube not live for me yet either (well, live but no music / dancing_

[haughty quiver]

please stand by i broke something!

[dawn bear]

okay that is purchased. 🙂

[waxen thistle]

Was Lars nibbling on the cables again?

[ebon stratus]

[haughty quiver]

i may have just fixed it

[waxen thistle]

Music is live!

[drowsy inlet]

did you turn it off and on again? 😉

[dawn bear]

Music!

[ebon stratus]

I need a spare Qualia for when I blow up the one I have. LOL

[unreal bay]

They are lovely boards, got the bar touch screen here and it's fantastic. Although take note there's no 5V pin available (need to solder a 2pin header around a capacitor for that 😆 )

[dawn bear]

I just picked one up. I like the idea of offloading from the MC.

[ebon stratus]

I have a pair of 4" rounds.

[split gazelle]

good afternoon folks

[ebon stratus]

Hello all.

[waxen thistle]

round lcds have me spinning in circles.

[verbal river]

ARGH I thought my Eurorack synth was done but now I've thought of another module that I have to make

"Just when I thought I was out... they pull me back in."

darn synths 😠

[cinder wind]

RGB666: the bitd-epth of the beast!

[verbal river]

better than 16-bit 5-6-5 @cinder wind

[cinder wind]

yeah but I'm used to 565 🙂

[sand lotus]

If you use 8-bit indexed bmp it doesn't make a difference color wise anyway.

12fps is really good considering most of the smaller TFT's do about 3fps typically using SPI.

[ebon stratus]

UPS is the only shipping available. NO USPS. Not going to place order.

[verbal river]

FYI there's a company that makes clocks for NASA that run 37 minutes slow per day, for JPL where people work the Mars shift.

[sand lotus]

the chip on the little ribbon cable can get really really hot btw

[ebon stratus]

@haughty quiver there's no USPS shipping option.

[sand lotus]

each different display requires a different init sequence

they're all different

[shell mason]

[verbal river]

I am seeing a USPS shipping option (ordering from Canada)

[dawn bear]

To California

[ebon stratus]

@haughty quiver there's no USPS shipping option. UPS onlly?

I'm only getting UPS, not USPS as usual. Weird

[ebon stratus]

Truly no USPS for me. No Order.

[drowsy inlet]

interesting. not seeing USPS either

[verbal river]

Has the US Postal Service stopped delivering to Minnesota???

[drowsy inlet]

IN for me

[bright prawn]

I'm seeing USPS as option in texas

[ebon stratus]

I guess God is telling me I don't need any. 😃

[verbal river]

So maybe the northern half of the country is cut off? 😮 Maybe we'll have to start driving orders down from Canada. Anyone in upstate NY can't get delivery, let me know. 😄

[drowsy inlet]

do you have other things in your cart? I did and removed them and now see usps

just realized i had the pi 5 rtc battery in my cart. usps won't do batteries. forgot about that.

[ebon stratus]

Crap. I thought it was just a battery HOLDER, not with the batey. That's the reason. Let's see if I can salvage this B4 sale is ovah.

[unreal bay]

nice1 mikeP, saved someone there, and I'll hopefully remember in future

[ebon stratus]

That's it. The Pi RTC battery. Removed and checked out OK. Thanks to whomever it was that caught that!

[cinder wind]

One of the most beautifully-designed displays I've ever seen on a Euroack module is also a round display, the Elektrofon Klang: https://www.modulargrid.net/e/elektrofon-klang

[ivory flax]

Bummed I missed the live show. Sounds like a good deal on the RGB666

[unreal bay]

still there if quick

[drowsy inlet]

can still get it

[sand lotus]

still might be time

[verbal river]

Beautiful! I'm trying to figure out what it does. 😄

[unreal bay]

normally til about 45past (estimate), sometimes sells too fast, and sometimes avaiable all night (rare mistakes)

[sand lotus]

JP usually takes it down shortly after the show but if people here in chat show up a little late he might keep it up.

better be quick about it

[grand tusk]

I got my order in!!!

Got the 320x960 display to go with it.

[sand lotus]

same, i have some round and square but don't have the rectangular one yet. got an ntc thermistor for a solar project too.

[ebon stratus]

@cinder wind that Klang is hot. It could be fun trying to desing something similar.

[sand lotus]

aaand it's gone. Thanks for keeping that one available for a while JP. I was on the fence but got in an order at the last minute.

[ebon stratus]

so I'm going back to my quest to find an answer to my BeautifulSoup library problem. 😔

[sand lotus]

stack overflow? there are a lot of Python users there with a lot of experience using that.

[unreal bay]

ah, got love for beautifulsoup, which channel and how's it let you down (i.e. whats the operator error 😉 )

[sand lotus]

I directed him to #help-with-projects since it's pure python related.

[unreal bay]

I see it now. So in VScode I have to switch the python interpreter between the avaiable environments. The other option is to pip install it in both. So open a terminal in vscode and run pip install bs4 (or whatever it is)

[ebon stratus]

I haven't done any coding for several mponths and I'm guessing something auto-updated. LOL. Terminal finds the BS4 module (from BS4 import BeautifulSoup), but all of the editors VSCode, Thonny, & Mu say module not found. I'm guessing there's been some path change or whatever but I"m clueless. LO gain.

[unreal bay]

so i had to copy my python path, that vscode uses when i press debug from the debug/vscode-terminal, into a new terminal and use it with -m for module and then pip to install bs4 and then it works

and you can change the python vscode uses with this button, or via the command palette

[sand lotus]

Please move this to #help-with-projects it's unrelated to broadcast chat.

Because every time someone chats in broadcast it pings people who have this channel setup for notifications.

[ivory flax]

Whee... I got my super duper discount on the the RGG-666. I love these boards... so easy to use and very versatile. I wish the displays were a bit cheaper but its worth it. Happy Holidays everyone.

[cinder wind]

wait, eurorack modules do something? I just hook them up and watch their lights blink

ugh Mac always leaves all kinds of invisible crud

[sand lotus]

so does windows

[vagrant flax]

I do the same thing and just delete them on a windows machine lol

[sand lotus]

windows creates these files for search indexing and trash cleanup.

[vagrant flax]

yeah same on Mac. Mac also loves these ds store files, and for every file you copy onto an SD card, it creates an invisible ._ file too

I think there's also an arduino example sketch that turns your MCU into a flash drive 🤔 I've used it a couple times

not necessarily any easier than using the "install CP" method though lol

[sand lotus]

someday hopefully we'll be able to mount the SDcard to Windows while connected to the board. that will make everything so much easier.

lovely fireplace, gotta go run errands. see you tonight.

@sand lotus Check out PyGame

and the home automation is just HTML with buttons

[drowsy inlet]

possible stupid question, but does pygame work with circuit python?

[cold elm]

touching the button with the touchscreen is the same as clicking on it

@drowsy inlet I have not tried it.

I've only used it on python 3

@open girder Another possible half-press solution could be a small force-sensitive resistor + haptics.

[delicate fractal]

in the factory footage, someone was shown handling a board wearing what looked like finger-cots... wouldn't those be bad in an anti-static sense?

[open girder]

@delicate fractal all depends, but for this, nope!

[delicate fractal]

And it turns out they make anti-static finger cots anyhow! did not know that!

that's impressive precision

[bright prawn]

yeah the JSAUX backplate for my steam deck came with a set of those

is it possible to turn this https://www.adafruit.com/product/1958 to use stemma qt instead of wiring it up manually? in other words, plug-n-play connecters.

[merry gulch]

Question: can you mix I2C sensor types on a single bus?

[tulip kestrel]

yes as long as the I2C address don't match

[sand lotus]

and even if you want to put multiple I2C devices with the same address then a multiplexer will fix that

[merry gulch]

Question: do hall effect sensors measure magnetic strength or just if a magnet is present?

[sand lotus]

https://www.adafruit.com/product/5664

Allows you to connect multiple I2C devices with the same address. Multiplexers are awesome for that.

[undone onyx]

can't see the TLA any way

[wild urchin]

Here we are!

[cinder wind]

I bet it's bad speaker again

[wild urchin]

Is the little LCD actually scanning or is that a scanline beat with the camera?

[grand tusk]

I could only fit 12 sliders on the touch screen.

[cinder wind]

that's pretty cool!

[unreal bay]

maybe the sliders could enlarge in width as fingers reached them, a bit like the glass ball screensaver back in the 90s, it would enlarge the screen where the glass ball was rolling (like a lense)

[grand tusk]

Thanks

That's a good idea!

[undone onyx]

sounds good to me

JP

[lavish patrol]

That level seems perfect. I can hear it and you.

[unreal bay]

I could imagine @grand tusk them swelling as a finger places, and adjacent swell too to make it easier for other nearby bar usage

[sand lotus]

yes can hear some of the harmonics when it phases over

sound is a bit low though

[wild urchin]

Is the orange light blinking box a USB MIDI Host?

[undone onyx]

DC wavwform + silence

[cinder wind]

yep. it's a https://retrokits.com/shop/rk006/

[undone onyx]

[sand lotus]

mm that sounds so nice. like the hum from a high voltage power station. the sound of energy.

[grand tusk]

Can it do PWM?

[wild urchin]

1.21 JIGGAWATTS!

[undone onyx]

de tuned osc lobes

[cinder wind]

not really. but you can emulate it by changing the waveform to emulate a PWM

[lavish patrol]

Getting a 1980s SciFi vibe...

[wild urchin]

"Teenage Wasteland"

[eager matrix]

I was thinking the same thing.

[unreal bay]

Whats the brain board on that thing JPs running?

[grand tusk]

Grouchy synth.

[sand lotus]

stuck notes would happen all the time with VST's and I never knew midi panic reset was a thing. could have saved myself a lot of time instead of restarting the entire program.

[lavish patrol]

Now I'm getting a Vincent Price vibe.

[grand tusk]

Pretty sure it is RP2040 based @unreal bay

[wild urchin]

It's Trinket-socketed, I think, so RP2040 or M4

[inner spade]

Itsy M4 in this incarnation. Analog DAC output.

[unreal bay]

thats what i was wondering, if rp2040 maybe could get more from the m4/m7.

or some crazy pio code eventually

[cinder wind]

probably not but the RP2040 can do a lot of good synth stuff. All of my CircuitPython-based synths are RP2040-based

[unreal bay]

what did you learn between versions?

[sand lotus]

great design! could always fit stuff on the bottom if you need more height.

impressed you squished everything in there, very well done!

[lavish patrol]

It's nicely laid out.

[inner spade]

That’s a very nice PCB design.

[cinder wind]

hmm Kicad doesn't do thermals for you by default for pads?

[sand lotus]

this is the reason why adafruit modules that keep the pinouts vs going stemma only is really handy. you can solder modules directly to a bigger pcb.

[unreal bay]

brilliant, thank you

[inner spade]

Usually, but it’s possible to select an ungrounded mechanical pad without thermal isolation.

[cinder wind]

ahh

[sand lotus]

EasyEDA does automatic thermals but they're usualy inadequate, especially for trying to heat up a copper plane on that size PCB... you'd sit there holding the iron on a ground point for 5 minutes.

[lavish patrol]

Another great Workshop, JP.

[wild urchin]

No John don't come for my wallet with a discount code.

[unreal bay]

could it be done with force feedback linear potentiometers?

[inner spade]

If you ground an ungrounded mechanical pad in your schematic, you’ll need a bigger soldering iron.

[grand tusk]

Thanks JP!

[inner spade]

Knock Knock

Hello from Los Angeles

[brazen grove]

good evening

[unreal bay]

Good evening 👋 slightly low voice volume, but maybe it's just gentle and nice

[sand lotus]

Good afternoon ☕

[dawn bear]

DJ Did you bring the shofar?

[sand lotus]

vanilla roast coffee. was up all night working on a menu system tracking down a driver issue.

[unreal bay]

ooh, which cpy menu library are you using?

or is it home-brew

[sand lotus]

adafruit_button. tried displayio_layouts but ran into the same issue... because the touch display has its own buffer where it's pressing twice.

[unreal bay]

ooh tricky

[dawn bear]

OH BLE Not belee

[sand lotus]

isn't file glider used for that?

[unreal bay]

got a few menu tabs bookmarked at the moment, but to be honest felt like it's going to be diy-ed, the grid layout etc I need to play with. Had a quick go with scaling IconAnimation (IconWidget base class), one of the built in examples with minor modifications.

[dawn bear]

I was gonna ask why not wifi over BLE? Power?

[sand lotus]

grid layout is ok, buttons work fine if they're kind of by themselves. using it with multiple pages gets tricky. found some issues aren't obvious if you have a black background like most projects. add in a background image and any layer issue becomes much more obvious.

is wifi over ble possible? whaaat. never heard of that.

[dawn bear]

Yes

Correct

[unreal bay]

printers love it

[dawn bear]

I was thinking more point to point. Not joining like a home net

[rigid crag]

ZeroConfig via MDNS

[sand lotus]

unless your local network has explicitly disabled multicast?

[rigid crag]

popularized by Apple as BonJour

[unreal bay]

yeah safety / bad routers getting in users way can defeat most good things

[brazen grove]

it's the avahi thing, no?

[unreal bay]

avahi in linux

the same page from the machines IP works much better, but browsers often fail accessing mdns things and need to retry/refresh

[brazen grove]

is this because there is a limit on the number of sockets open simultaneusly?

[rigid crag]

browsers used to be very bad at doing .local because they bypassed the local OS for DNS

[unreal bay]

not so sure on the socket front, although fortunately we may watch scott find out, but if you refresh the mdns site in the browser a few minutes later it will often struggle to get a lookup response, or at least that is what it feels like

[sand lotus]

probably 99% of people have multicast enabled or don't even have an option to disable it. i wasn't a fan of the multicast broadcast protocol so I disabled it to make my network more efficient... but you do miss out on the new mdns features like web workflow uses.

[unreal bay]

or displaying a qrcode

[sand lotus]

i think there were a few minor fixes for certs even after 8.2.4, possibly related?

depends if inky run a coprocessor?

[unreal bay]

https://adafru.it/discord

[sand lotus]

#help-with-circuitpython is the place to ask for Circuit Python support questions in this Discord. All are welcome to join just read the Code of Conduct first.

[dawn bear]

Yes. Picked up JPs PPOW which is a S3 RGB display driver

[sand lotus]

After finding json_stream I'm probably going to be using that for all my JSON API uses going forward. It's sooo much more efficient.

[dawn bear]

This one. And a display https://www.adafruit.com/product/5800

for 10 bucks I thought it a steal. For the board.

[rigid crag]

i've been enjoying the new web/wifi workflow - I can edit multiple devices at the same time to test

[sand lotus]

ohh does it have tab completion or are those other types of features planned for "someday"?

i would love to have the features of pycharm. Mu has very basic set of tab completion compared to pycharm.

[rigid crag]

are you thinking about enabling remote dev in VSCode using wifi or usb?

true, all you really need is an endpoint to update a file and then monitor the serial output

[wary zephyr]

This is Shannon. Yay. I’m on the discord now. 🙂

[sand lotus]

Welcome to Adafruit's Discord!

[unreal bay]

i had the mad impression that sd showed on web workflow

[strong acorn]

will SD also show on USB workflow?

[sand lotus]

It's like working with text files on a USB drive. Instant save and program run vs Arduino waiting 5 minutes for a compiler to finish between iterations. Instant iterations = faster developing.

[wary zephyr]

Ty

[dawn bear]

So that is blinka?

[sand lotus]

Blinka is the compatibility for small board linux machines like Raspberry Pi 3/4/5. Blinka is slightly different from Circuit Python that runs on microcontrollers but they try really hard to make it all run the same with the same features.

[eager matrix]

Why aren't you supporting LVGL for graphics with CP?

[dawn bear]

Oh! @sand lotus thanks. I thought it was the common API (for hardware). Cool. I did not know.

So why CP + Blinka as opposed to straight Python? Size? The I/O headers?

[strong acorn]

libraries for all of the I2C, SPi, etc. devices

which are dependent on microcontroller modules

but you can intermix CP libraries and CPython libraries with Blinka

[sand lotus]

With a Pi 3/4/5 you also get all the power of Linux with Python. Microcontrollers are too small to run those types of large libraries, just not enough ram or storage. Circuit Python for microcontrollers is a really squished down version so it can run on really tiny microcontrollers.

[rigid crag]

ports is an old term when you are trying to get your code "ported" from one environment to another

there used to be a FreeBSD package collection called Ports

[dawn bear]

I guess I meant why run CP on Pi?

I guess he said speed of dev

[sand lotus]

Porting is when you take 1 project from 1 platform and transform it to run on another. The term "port" for Circuit Python means porting a Microcontroller's SDK (they all have their own like ESP-IDF, NRF, Atmel, etc..) so that all of those boards can work on 1 platform.

[strong acorn]

running CP on Pi with Blinka gates you access to a huge base of device driver and helper libraries for sensors, etc

[unreal bay]

the idea is to make the software portable between architectures. and HAL = Hardware Abstraction Layer

[dawn bear]

Yeah I been coding since 1986 and we've always called it porting.

So Ports makes sense to most engineers

[rigid crag]

yep, coding professionally since 82 - same

[dawn bear]

I guess I thought blinka was thee HAL

[unreal bay]

if you master circuitpython, you'll have little problem switching to micropython + lvgl down the line

[sand lotus]

At the time yeah it wouldn't work on an ATMEL 8-bit AVR or SAMD21. Maybe about the time of the M4. Now with the ESP32-S3's it might be possible. Unsure if the newer iMX...

[eager matrix]

I might. I'm just starting to work with it on ESP32 and if I've got the time I'll take it on. I'll let you know.

[dawn bear]

@eager matrix Yeah I am getting that board JP pushed this week. Its an S3

[sand lotus]

Here's a project I did with the RP2040 DVI board to HDMI. It's possible to merge them with OBS for neat overlays. Was the most practical example I could come up with. https://www.youtube.com/watch?v=05BcstyL144

[dawn bear]

@rapid hornet Your explanations are very clear

[sand lotus]

When boards come out with more ram and storage with DVI I think the possibilities of HDMI with Circuit Python will expand.

Happy Holidays Scott. Hope everything is going well with what you've been dealing with lately. ❤️

[eager matrix]

OK here's another one. Why doesn't Adafruit carry the Swan Feather from Blues Wireless. It's got a STM32L4+ @120MHz.

[nova totem]

And things do get done from those yearly posts. That is where I got the want to work on gifio when Anne wanted it and I thought, that would be a cool project

[sand lotus]

I think a lot of the STM chips were unavailable for a while during the chip shortage.

[dawn bear]

I think they concentrate more on their own designs and products

Best to you and family

[sand lotus]

If I can get multi-pages and menus working on my feather weather I want a page dedicated to running gifio for NOAA radar images. They provide them in sequence with the filenames always the same. All anyone has to do is download them every 15 minutes, combine them into a gif, and run it on the display. Saw that Carter has a learn project similar. Getting multiple pages working has been more difficult than expected.

[unreal bay]

concatenate them instead and called it mjpeg (there might be a bit more to it than that)

[sand lotus]

Gifio, PNG support, mJPEG decoding... these things take time. Circuit Python is slowly and steadily improving in all areas.

[nova totem]

I played around with compiled modules and it is a lot of work, and even the MP implementation isn't perfect. The core is so much easier (I started typing this as Scott said it ha)

[wary zephyr]

Man…I have to many hobbies… hard to dedicate time to them all. But I enjoy them all. Learning how to program seems like it’s going to need a lot of time to learn. Honestly this seems really overwhelming at times. I have ideas what I want to do but lost on how to get them done. Hope there is a really easy place to start.

[sand lotus]

Learn + Search is the best place to start. Also choosing the right boards for your project goals is important.

[wary zephyr]

I am enjoying the stream! You explain things well. Is it learn.adafruit.com ? I’m on my phone and hard to read.

[sand lotus]

The Essentials learn guide is like the Circuit Python bible. Even years later I still refer to it almost daily.

[dawn bear]

@sand lotus link?

[rapid hornet]

https://learn.adafruit.com/circuitpython-essentials

[sand lotus]

First time I tried creating a new board was the first time I learned the terms "mebibits and gibibits". As if converting MB /1024 to GB wasn't hard enough.

[eager matrix]

Just some info - A company called tq-group released a board with an NXP i.MX 8M Plus processor in a board with the same format as a raspberry pi and that runs Pi OS. You can also do custom builds with Yocto. It's got 4 A53 cores and 1 M7 core along with an ML block. I don't know the price yet but making a board like this in Raspberry Pi format is brilliant and I hope more companies make them.

[dawn bear]

AH. I was on the CP site

[sand lotus]

BLE Central was the biggest missing part, that people most often asked about.

[wary zephyr]

@rapid hornet thank you

[sand lotus]

It's not just Pi's in the SBC format. Also Beagleboard and others.

which is why we have #help-with-linux-sbcs instead of help-with-raspberry-pi

[glad mortar]

heyhey

oh how would you make littlefs work? translation on the fly to fat?

or is this not the fs mounted via usb?

aah ok

makes sense

oh quite a bit of latency with chat haha

[sand lotus]

Have yet to use octal psram, would that make file transfers faster to SD or would that only be relevant to onboard stuff?

[dawn bear]

So it is getting late. And you are tired. And have stop on the way home. And I have to run... all the BEST to you... 2023 has been terrible for me... but I wish you and yours ALL THE BEST. Seee U next year

[wary zephyr]

good morning ☕

[smoky island]

I'm getting started for the morning now. Using the Adabot library release utility on a full sweep for the 1st time. You can follow along on YT: https://www.youtube.com/watch?v=KWhhdtvbF4Y or twitch: https://www.twitch.tv/foamyguy_twitch

[sand lotus]

i've been up all night and had a very productive coding session. exhausted so it's actually good night. 🛌 hope you have a nice stream i will be unconscious shortly.

[clever summit]

Hey Tim!

[inner spade]

Good morning! ☕

[clever summit]

Five in the afternoon here.

[inner spade]

Eight AM here.

[clever summit]

You do realize that AM and PM is not know acronyms in this part of the world? 😆

[tiny grove]

They're not even acronyms in 🇺🇸

[clever summit]

The only AM I know is the one that goes with FM. Old school radio, baby! 🙂

Yeah, time here is 17:13.

Or as we say, quarter past five.

🙂

[grand tusk]

kwart over vijf middags

[clever summit]

Is that v pronounced like f or v?

[unreal bay]

Whats going on here then, have or do the versions of each library/module changed too, like each one has a new version updated in repo (and potentially release)? or is it just switching the reference of each submodule to latest ref?

[inner spade]

Latin: ante meridiem. American English: “at morning.”

[inner spade]

Good to know!

[unreal bay]

got you, so each library needs a new release due to CI changes, my question was if each library repo also contains a version somewhere in a file that needs updating too

[clever summit]

Discord can sort it out. <t:1702138860:R>

Totally localized.

[unreal bay]

That was very helpful thanks

adabot does two joined queries for the repo list (at least in arduino) so i get two alphabetical lists concatenated

[unreal bay]

lol, wrong room, well spotted. yeah noise cancelled

[unreal bay]

yeah definitely, as the dev you should recognise oh its not 1 commit so I should look at it

if using a personal access token then the limits are generous like maybe 5000 api calls per period (hour?), otherwise it's only hundreds, ran into it testing adabot without a token (just checking changes on public repos)

yeah gh auth login uses more future proof version than personal access tokens

[rigid crag]

yes, if you use oauth to login then github will inherit the parameters for calls

M is technically half way, but depends on the distribution of names

draft PR?

for our work codebase, I often run a report to flag any branch with PRs that are older than X days, or have pending merges -- it's so easy for some of the lesser active repos to get skipped

oh my yes (the old branch cleanup) - do you have the merged branch being deleted by default?

yes, branches you control :)

for the curious, this is where it is in GitHub -- https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-the-automatic-deletion-of-branches

[unreal bay]

I've not got branches monitored, but each bump release needs a file with version number updating too, so I (or the script) get to check CI before merging that, as a precursor to safe release. I've also gone wild and got the browser windows popping open so I can use that new "Auto generate release notes" button, as it's not avialable via API yet, walk away for coffee while it runs...

[rigid crag]

does the token have the proper scope to push release metadata? write:package ?

if you are calling submodule from the command line and referencing the path - then it's directory order

yes, the python socket default timeout is 90 seconds

oh! python requests DOES have a timeout parameter - learned something new today
https://requests.readthedocs.io/en/latest/user/advanced/#timeouts

nope - 90 seconds

you have to say timeout=None to have it wait forever

[strong acorn]

separate connect and read timeouts is handy too

[rigid crag]

[drowsy inlet]

yeah, so in that case i'm guessing the Euler angles would come from the quaternions and most likely there shouldn't be gimbal lock issues. again, was just curious.

thanks jp!

[cinder wind]

yeah that's a good question. The datasheet seems to indicate it's doing real quaternions and not just faking it https://cdn-learn.adafruit.com/assets/assets/000/125/776/original/bst-bno055-ds000.pdf

[tiny grove]

Mechanically, I don't think MEMS gyroscopes are susceptible to gimbal lock, as their "gimbals" don't really rotate (I think they might oscillate instead). Mathematical gimbal lock is still possible though, and that's where quaternions become useful.

[cinder wind]

which is different from Gimble Loch, a small Scottish sea famous for the Gimble Monster

👋

really nice case, I like the exposed bonnet so it obscures the rest of the dev board. kinda makes me want to re-start development again for the WipperSnapper on RasPi..

this combined with the mars clock has made me more confident with circle math 😀 i also meant to mention i'm using your ahrs library from the community bundle for the mahony filter

[nova totem]

So glad it is getting use! That was my first CP contribution I think. At least of any complexity.

Some excellent projects tonight. Thanks for sharing!

[haughty quiver]

they had the candle elements on the pick a brick wall @nova totem ? I gotta go see if our LEGO store has them too!

[nova totem]

Yup, lots of green and red bricks and all the candles you could ever want. I want to grab a few more even unlit for the back side of the tree where I removed them.

[haughty quiver]

awesome. the temptation is to fill a large pick a brick container entirely w candles and then figure out what the heck to do with them 🙂

Thanks @cinder wind I've already got your CircuitPython and SynthIO tips bookmarked. Use frequently! Thank you

[gray obsidian]

Oh, I noticed some tricks that were used for non 5V FPGAs where you'd add a resistor and it'd be enough…

[delicate fractal]

A lot of Louis Rossman's problems would be better handled by hiring a lawyer, which he refuses to do.

[gray obsidian]

Well, I could write books about the French administrations, so… 😅

[nova totem]

No matter your business or location you need a set of lawyers

[gray obsidian]

Probably, at some point he probably could have afforded one

[delicate fractal]

I'm sure he'd make his money back just in terms of life-span lost due to stress.

[gray obsidian]

Well, the problem is when you start you usually can't afford a lawyer, then you probably don't think about it, or don't want people to interfere with how you do stuff…

[delicate fractal]

lol

[gray obsidian]

I once worked for a German company and I had to handle that with an administration at the other side of France…

[glad mortar]

running a electronics business in Germany (and to larger extent the EU) is really difficult compared to the US. Loads of regulations that are fine if you are a larger business but can be a real challenge if you are bootstrapping.

[open girder]

[nova totem]

In Canada (at least) there are a lot of government programs to help you get started too and will give you cheap loans or other grants to start. Just have to find them. The one my brother went through set them up with a mentor even.

https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Boards/espressif/Adafruit Feather ESP32-S3/3.5 TFT Featherwing/Feather Weather MQTT Touch

[sand lotus]

Mostly for family members that are used to device having everything self-contained

[dawn bear]

hey tim! Sorry I am late!

[sand lotus]

STMPE610 is the touch controller for the 3.5" TFT Featherwing

adafruit_touchscreen might work for the TFT featherwing, I just choose to use the base library instead of the abstracted adafruit _TFTfeatherwing helper library.

skipped the helper library and went straight to the touchscreen driver library

I did use CGrovers calibrator to make my TFT featherwing accuracy much better.

and then subtituted those values in my code.py for the touch screen init

i think we're on alpha 6 as of yesterday

but i'm still running 8.2.7 on feather weather because i need my main project stable.

fourwire was changed to busdevice i think

a lot of display and protocols have been renamed in 9

[wind spoke]

Sounds like math...

[sand lotus]

0,0 is the first row. 1,0 is the send row, an so on.

[wind spoke]

You could have 6 keys for Space giving the same value/effect, but visually it is one long key.

[glad mortar]

heyhey

heh, very on-topic for my own work today

yea getting some of the new products ready for the big RPi, mostly kernel and device tree stuff

[wind spoke]

If only we could have a Qualia based virtual keyboard on those touchscreen long display... and the keyboard will actually compute a usb-hid keycode that can directly be used for keyboard emulation...

[sand lotus]

print(f"Get Grid Cell H: {layout.get_cell((5,2)).text}")
print(f"Get Grid Cell E: {layout.get_cell((2,1)).text}")
print(f"Get Grid Cell L: {layout.get_cell((8,2)).text}")
print(f"Get Grid Cell L: {layout.get_cell((8,2)).text}")
print(f"Get Grid Cell O: {layout.get_cell((8,1)).text}")
``` this for me prints out `HELLO`

[glad mortar]

you mean as in to build a usb touchkeyboard for plugging into a computer?

[wind spoke]

Yes a keyboard that you plug in your computer, but it is a screen. (and you can then change from AZERTY to QWERTY or even QWERTZ) 😉

[glad mortar]

that sounds useful yea 🙂

[sand lotus]

might be padding to take into account

not sure if padding is cell interal or cell exteranal

[dawn bear]

Wow. No shape (rectangle) to do a 'contains' operation?

[glad mortar]

as someone who switches a lot between German and US ANSI layout that would indeed be useful as a dev keyboard if it also does mouse

[unreal bay]

hey, late to the party, have you seen the icon animated example? Just played with it recently, had a quick check and it uses .contains, which is defined in iconwidget which calculates the widgets x/y and calls off to super().contains (displayIO.Group)

[proper prawn]

Hi Tim and all present

[sand lotus]

make it functional first, can make it pretty with labels laters considering ram use for lower power boards.

[unreal bay]

i wondered if you tried a .contains on each group in the cells list would that work?

[dawn bear]

@sand lotus Problem is, often ugly code gets left behind once its 'working'.

[unreal bay]

better option, yeah i would like the helper function, also like attaching callbacks to cells for click would be helpful

[modern night]

o/ Howdy all, been awhile since I've been able to catch one of these. Hope everyone's doing great!

[sand lotus]

if there are no errors or bug reports then your coe is valid. 😛

[wind spoke]

Tell me about it... I am between French/Belgian, French/France, US English and UK English.
Right now, the only touch capable rectangular TTL TFT display I find with Adafruit is this one:
Capacitive 3.2" 320x820 RGB666 TFT Rectangle Bar RGB TTL TFT Display - 3.2" 320x820 with Cap Touch - TL032FWV01CT-I1440A PRODUCT ID: 5797
I think that is too small for a reasonable keyboard... I wonder why most of the touch screen are the square one and the circular one.

[light stump]

Friday widgets with Tim: it’s a great day for deep divin’

[sand lotus]

touch gives you x,y, touch pressure

i get no problems like this on 8.2.7 but i'm also not on a pyportal

[wind spoke]

Time to switch to Mu?

[glad mortar]

yea some more cap touch displays in the 4-7" range would be nice

[sand lotus]

Mu won't help if the font doesn't display the unicode character on the display.

[dawn bear]

Yep that is me too. Symbolic math is the worse

[sand lotus]

it should work on smaller displays as the grid layout is dependent on the display height/width for what creates each cell size.

a 160 oled for example it'll have issues with so there will be minimum display size limitation.

[rigid crag]

col = row width / cell width
row = grid height / cell height * cell height
(from memory but that gives you a x,y grid that you can then look into an array
hrmmm, yea, this is stubbornly harder than it looks)

[wind spoke]

I think the // (floor division) will be used to have an integer result.
So first make sure you are in a 0,0 referential.

[rigid crag]

yes, take advantage of integer division
