Heh, put RFID sticker on tip of magic wand and you have to "cast spell" to solve escape room puzzle

[smoky island]

I love these outlet relay devices. I do not trust myself at all to touch real "house level" voltage but these allow me to safely hook up systems to turn on and off all sorts of ordinary gadgets.

[viral sail]

Thanks @haughty quiver. Have a good weekend.

[inner spade]

Thanks!

[haughty quiver]

thanks very muchfully!

[smoky island]

Thanks JP, another great show. Always a great to hang out in the workshop with you.

[haughty quiver]

thanks @smoky island !

[waxen bough]

This device isn't available at Adafruit or anywhere else! I've been looking for a while now to control my 3d printer. But no...😥 I can't find anything even remotely like it. Any help?

[haughty quiver]

@waxen bough not sure if this is a re-labeled version of the same one, but sure looks like it https://desco.descoindustries.com/DescoCatalog/Monitors/Single-Wire/Full-Time-Monitor/19323/

[polar lake]

sadly, i think that product falls in the sweet spot where the general demand is low, and the people that need it are knowledgeable enough to wire up their own with outlets, junction boxes, and relays.

[smoky island]

We've got a little bit different type of Deep Dive planned for today. We will be discussing and looking at all things CircuitPython Library related, we'll be joined by special guest Kattni for this episode. If you are interested in learning about, or have any questions about CircuitPython Library development join us at 2pm Pacific US, 5pm Eastern US. Or 6hrs 10min from the time of this post no matter what timezone you are in. See you all on YT / Twitch and other streaming platforms as well as here in the Discord chat!

[noble grove]

Shouldn't this be on live-broadcast-announce?

[turbid hill]

in a half hour

[noble grove]

oic

[smoky island]

That one is all automated I believe. The bot posts automatically whenever a stream is going live.

[noble grove]

Sorry. I was thinking it was an hour before. Not paying attention.

[turbid hill]

timezone difference

[smoky island]

No worries, I appreciate you mentioning it to help out in-case it was meant to be over there.

YT link for today's show is here: https://www.youtube.com/watch?v=sjAP2ZobsHY we'll be starting up in about 25 minutes.

[left pier]

does the Twitch stream still have the least lag ?

[nova totem]

usually

[noble grove]

Hello Tim

[inner spade]

Hello!

[noble grove]

Some kind of echo going on

[turbid hill]

yo

[noble grove]

Hi Kattni

[turbid hill]

Yes it's a python shoot out

[clear matrix]

Hello, everyone!

[left pier]

[nova totem]

Hello everyone

[noble grove]

not anymore

[inner spade]

No echo on this end of the YT stream

[turbid hill]

no echo but lips and audio is slightly out of sync

[noble grove]

got the pdf

yeah, video is about 1/2 second behind the audio. I just stop watching Tims lips.

[turbid hill]

Delete libs, nah just get more contollers

[inner spade]

? Is there a difference between a “driver” and a “library”?

[clever summit]

🇸🇪 👋

[smoky island]

https://github.com/adafruit/Adafruit_CircuitPython_Bundle

[noble grove]

Some libraries are drivers, some libraries are helpers.

[upper sandal]

[inner spade]

Some libraries have drivers with helpers.

[nova totem]

Community bundle I think was my first CP contribution

[smoky island]

https://github.com/adafruit/CircuitPython_Community_Bundle

[viscid bolt]

Is there a document that lists all of the libraries, a description of each module in a library and example code on using it?

[clear matrix]

There's this list, which links out to documentation that contains the rest of what you're looking for. https://docs.circuitpython.org/projects/bundle/en/latest/drivers.html

[viscid bolt]

Thanks. I'll check it out.

[turbid hill]

requirements is a way of handling dependencies in python

[upper sandal]

hmmmm I would actually argue that it is sometimes easier in Arduino

[left pier]

Or, you could use CIRCUP and not have to remember file vs. folder 😉

[turbid hill]

yes use circup

[upper sandal]

yep, the seesaw submodules naming is a source of problems sometimes

[turbid hill]

change your file manager to list view from icon view

[upper sandal]

(the other issue is when people use the guide's code from seesaw import neopixel and find themselves unable to use the built-in neopixel)

[turbid hill]

If you grow up on C/C++ arduino is easy

[upper sandal]

👋

[turbid hill]

woot QBasic

[noble grove]

I've used QBasic

[turbid hill]

I broke qbasic

[clear matrix]

"pip Installs Packages"

[turbid hill]

I made a data set in qbasic that was so large it broke it, thats when I switched to C and started learning structs and pointers

[smoky island]

https://learn.adafruit.com/keep-your-circuitpython-libraries-on-devices-up-to-date-with-circup

https://github.com/adafruit/circup

[upper sandal]

I would be happier if we had a UI for circup for beginners, copying by hand does not get you the dependencies automatically, that's one of the things that I would consider usually easier in Arduino

[smoky island]

https://learn.adafruit.com/

[upper sandal]

or like a web page that creates a zip for you from a code.py you drop on it, and has a list of libraries, you check what you want and it packages the dependencies with it in a zip

[turbid hill]

Also feel free to improve the guides, all guides have a button for sending improvements

[ionic garnet]

Hi folks late but here

[left pier]

Off Topic: 50% of the time, I solder the pin headers on the wrong way... 🤦

[turbid hill]

lol

get that desoldering gun out

[upper sandal]

well the project bundler in still internal to Adafruit, it would be great to have a tool for everyone

[noble grove]

Oh, that's nice. Feedback link. That's new.

[clear matrix]

https://blog.adafruit.com/2021/05/03/what-is-bundlefly/

[upper sandal]

[left pier]

OR if you are always setting projects aside and coming back to them later.. circup upgrades the libraries and tells you if your CP build it old too.

[turbid hill]

you can specify different circuitpy dirs

[upper sandal]

you can circup --path /path/to/drive

[left pier]

Also, finding a library...

circup show -- show all libraries in the bundles
circup show py -- show libraries with py in the name

[cinder wind]

yay circup!

[turbid hill]

you can use list --all to see all libs

sorry show

update --all

[ionic garnet]

I love this

[cinder wind]

"hey is there a CircuitPython library for a LIS3DH accelerometer?" circup show | grep lis3dh "oh there is"

[grand tusk]

Q for Kattni: How many guides you you write in a week?

[turbid hill]

circup will also show if your CP is old and there is a update for that board

[left pier]

@cinder wind you don't need use grep...

circup show lis3
adafruit_lis331
adafruit_lis3dh
adafruit_lis3mdl

[brazen quail]

Hola from 'rado ! :-D

[cinder wind]

lol oh yeah but I use grep on everything. it's like black pepper

no no show @left pier's version

[grand tusk]

circup show | select-string lis3dh

[turbid hill]

windows you can install grep

[left pier]

(lol.. video lag is silly frustrating)

[ionic garnet]

make believe it's black pepper

[grand tusk]

The guides are super useful. Thanks!

[inner spade]

? Is typing and doc markup required or recommended for community bundle contributions?

[left pier]

@clear matrix 's status reports are impressive. She gets a LOT done!

[ionic garnet]

I read all of Kattni's guide and source code

[noble grove]

circup not working for me. circup update --path /media/gordiegii/PYPORTAL1

[upper sandal]

--path before the update command

[noble grove]

thanks

[left pier]

There is even a way to get autocomplete to work with Circup... but its a tad wonky to setup.
https://github.com/adafruit/circup#id4

[noble grove]

Great. ```WARNING: 'adafruit_adt7410': mpy format doesn't match the device's Circuitpython version. Updating is required.
Do you want to update? [y/N]:

[turbid hill]

going to add that autocomplete it's straight forward for linux people

[inner spade]

? A bit beyond libraries: Have you considered hosting a linked collection of community CircuitPython full projects?

[upper sandal]

there is https://github.com/adafruit/awesome-circuitpython

[inner spade]

^Thanks for the A to my Q!

[inner spade]

Ah yes! Thanks!

[noble grove]

Is there a way to know which version of CP a particular library is compatible with?

[left pier]

The Awsome of Awesomeness 😉
https://github.com/sindresorhus/awesome

[noble grove]

It would be nice if circup would say which ver of CP was required to use the newest version of the library.

[upper sandal]

there is no versionning of libraries in the bundle, it just targets the latest stable release, and possibly includes compatibility code for previous versions to avoid breaking too much

[left pier]

@noble grove Just go to latest... always go to latest.

[upper sandal]

the message about the MPY format has nothing to do with the version of the library

[left pier]

CP gets more awesome in every build...

[noble grove]

I have the latest CP and (half an hour ago 7.2.5) circup gave me the error for the library

[left pier]

If your circup is up to date, it will give you a link to the downloads page for your board.

[upper sandal]

that means you had a library that was a version of MPY for CP6 on the board, or it was a bug in circup

[clever summit]

Also please download the swedish version to show some love for my work. 🇸🇪 🙂

[turbid hill]

If all else fails after updating to latest stable you can simply remove all libs and use circup to re install them.

[grand tusk]

Why would you have both .py and .mpy installed?

[left pier]

fixing bugs in a library

What Kattni said ...

[smoky island]

https://pypi.org/project/mpy-cross/

[upper sandal]

no no no no

don't use the micropython version !!!!

[polar lake]

why is that?

[upper sandal]

it doesn't work with Circuitpython

you can download the CP version from S3, I'm looking for the link

[clear matrix]

https://adafruit-circuit-python.s3.amazonaws.com/index.html?prefix=bin/mpy-cross/

[upper sandal]

note that the page has many versions, they are basically all the same, there's really only CP7 and CP6

[clear matrix]

Choose for your OS.

[smoky island]

https://github.com/adafruit/circuitpython/tree/main/frozen

[polar lake]

if .mpys are incompatible between MicroPython and CircuitPython, perhaps there should be a cpy-cross that makes .cpy files instead

[turbid hill]

In that docs area where all the libs are there is a page that lists all the boards and all the frozen stuff per board

https://docs.circuitpython.org/en/latest/shared-bindings/support_matrix.html

[upper sandal]

hmmmm we can add the frozen modules, I think it would be relatively easy

[noble grove]

I answered 'y' to all and now it works.

[left pier]

@clear matrix Any common issues you've seen or suggestions for people to want to make a new library?

[smoky island]

https://learn.adafruit.com/contribute-to-circuitpython-with-git-and-github

[turbid hill]

you might have to translate datasheets

[left pier]

Writing a bunch of functions in code.py and then moving to a library later is an excellent suggestion !

[turbid hill]

Can you have other .py files in the root that you import in your code.py so that you don't have a big monolithic file

[inner spade]

I love a good data sheet challenge!

[turbid hill]

google translate on your phone

[noble grove]

@turbid hill Yes, like secrets.py for example.

[turbid hill]

ahh ok

[noble grove]

@turbid hill I also use pallet.py and localization.py

[turbid hill]

ok

[left pier]

For future reading about MPY files and how they work ..
https://docs.micropython.org/en/v1.12/reference/mpyfiles.html

[upper sandal]

note that CP7 mpy files start with "C" instead of "M"

[smoky island]

https://learn.adafruit.com/contribute-to-circuitpython-with-git-and-github/giving-a-review

[noble grove]

Those are my own thing. Pallet is just a huge block of colours, and localization is just stuff that you might put in secrets.py but I think they don't belong in there.

[cinder wind]

Yes, testings PRs on real hardware is very much welcome

[left pier]

Ah, the first byte of the file is C not M... (I got confused for a second and thought it was the file extension)

Did you cover pre-commit ?

[turbid hill]

Lint, or a linter, is a static code analysis tool used to flag programming errors, bugs, stylistic errors and suspicious constructs.[4] The term originates from a Unix utility that examined C language source code.[1]

or "hey pylint became sentient, is bored, and just wants to heckle you"

[smoky island]

https://github.com/adafruit/cookiecutter-adafruit-circuitpython

Need something like that for automatically porting arduino libraries to CP libraries.

[smoky island]

Getting started with today's stream now. Jumping back into the TileGrid PR for the core. Hang out here in the chat and follow along on Twitch: https://www.twitch.tv/foamyguy_twitch or YT: https://www.youtube.com/watch?v=P9fvSvi_Qu8

[inner spade]

Hello

[upper sandal]

so yeah I would use a struct if you do it like that

where is you self_in error ?

well in the constructor that's just self, it's created there

well it's created where you want, but you want to test the input before creating it, so yes you should pass the parameters you want to test rather than the object

oh wait

you are modifying tile_width ?

you want to pass it as a pointer then

oh ok

lemme see if I remember

void function_that_takes_a_pointer(int *width) {
    *width = 5;  // <---- dereference to modify the value
}
function_that_takes_a_pointer(&width);  // <---- pass the address

whitespace doesn't matter

you need it for the modulo in the next line though ?

it is a difference in whitespace

int* width is int *width

think of it as an operator

1+ 1 == 1 +1

I think it would work, it's just uglier

hmmmmm that won't work though

unless you assign them back adfterwards

which you will have to do, because they have to be converted back to python ints

hmmm

native and bitmap are pointers, any change to native is a change to bitmap, except that when doing it with native it knows about its structure because it's the right type

you would pass native instead of bitmap I'd say

no that's because it's a pointer now

you need to dereference it with *

I hope I understand what you want to do, and am not pointing you in the wrong direction

it tells you it's of type void*

which will never change

remember, C is statically typed

void* means "any pointer to anything" so bitmap->whatever never means anything

so you do a "cast", to make the compiler see it as something else, it doesn't change the variable, it changes how the pointer is seen

bmp is bitmap, but cast to the right type, so it knows what ->width means

yeah, because each subtype has a different structure, you need to cast to the right type to know where width is in the structure

lets leave that as an exercise for Jeff next time he looks for code to deduplicate 😉

is it possible for tile_width to be 0 ?

outside of init I mean

so when setting bitmap all you need to check is if the size is a multiple of the tilegrid width and height ?

or do you resize the tilegrid ?

hmmm I see

so if you set a 32x32 bitmap, and the tilegrid is 32x32, then you set a 64x32 bitmap, the tilegrid is half the expected width

[noble grove]

What in python corresponds to the dot h file in C/C++?

[upper sandal]

nothing, it's not needed

but you can have stubs

[noble grove]

What are stubs?

[upper sandal]

stubs are declarations without the code, that can be used to inform an IDE of the API of your functions/objects/etc.

but they are not used when running python

(unlike C header files that are required in the compile process)

[noble grove]

So referring to functions at the top so the compiler won't throw errors but defining them below the main code ?

So dot h stands for header?

[upper sandal]

yeah in python you want to define things in the right order so that they see what's above

well that's not entirely true, it's more that it needs to be defined before it's used (in time, not in code position)

so functions "see" each other no matter the order they are defined, but global level code only sees what's above

[noble grove]

So it needs to be a multiple of full tiles.

[inner spade]

Appreciate today’s stream @smoky island. Had to pull out my dog-eared C++ cheat sheet, though.

[upper sandal]

that gives you that:

def call_one():
    call_two()

call_one() # <--- crashes because call_two unknown at that time

def call_two():
    print("hello")

call_one() # <--- is fine (if the other is removed)

[noble grove]

Curious

ic

@upper sandal I see

@smoky island sounds reasonable

[inner spade]

Changing size is problematic if you’re running close to memory limits.

[noble grove]

Thanks foamyguy

I think it was Edison who said "I haven't failed, I've just found 100 ways not to do it"

[upper sandal]

[inner spade]

Experiential learning works best for me. These streams reinforce that. Thanks!

[noble grove]

Sometimes thrashing around discovers another right way to do something.

[inner spade]

Life is a sandbox learning experience, after all.

that's pretty wild

[pearl shoal]

Sounds great - no copyright issues w/that music?

[viral sail]

That's really neat. I never saw one of those before.

[pearl shoal]

Q: Does it have a needle? Is it optical?

[ionic garnet]

I remember seeing one once! It was probably at Sony Electronics or Sony Music.

@open girder Or open sourcing it

[pearl shoal]

I'd like to see Sony at least do what MS/Google/Nintendo have done & support the XBox adaptive controller.. I wouldn't hold my breath on them.

[viral sail]

Did they actually include the schematics when you bought the unit or were they released some years afterwards?

[open girder]

@viral sail included, part of the service manual

[pearl shoal]

Very cool! didn't know an ESP32 could work as a router. It will expose two networks?

[clever summit]

Hey PT/Ladyada - Can I get you interested on going on the Simple Electronics podcast? Scott and JP has already been on.

[open girder]

@clever summit we'd like to go on every podcast! it's always a matter of time and not being able to do everything lately we wanna do, running an adafruit and taking care of our team/customers is the priority, so! drop a note to [e-mail] and we can at least have each others contact info, maybe won't be right away, but maybe the summer will give us a few hours to things like podcasts!

[clever summit]

Perfect! Will let Dan know!

[grand tusk]

Can the MMC5983 detect magma displacements?

[pearl shoal]

Q: Could that be used to quick charge LiPOs? Start @ 5V and increase the voltage when you're charging?

RS485 adds multi-drop right?

[nova totem]

RS485 does have multi-drop. Years ago all the peripherals I had to use were 485

[pearl shoal]

Long ago and far away I had to manage PLCs for Energizer

[nova totem]

I was working on lottery terminals (to buy powerball type stuff). All the scanners and printers and displays were RS485

[pearl shoal]

Limor moved one of those pins (far left second row from the top) - I'm sure she'll notice but if I don't mention it I'll feel bad

Q: I noticed that the one you chose was "Tube" not Tape or DigiReel - can your pick&place work with individual parts? Or will you just find one w/Tape in stock

Thanks!

[viral sail]

Thanks and good night. 🌕

[clever summit]

Hi Tim. 👋

[inner spade]

@smoky island Perhaps a guide for “ moving beyond big helper libraries “

Would help with memory management issues, too

I’ve dissected the big helpers in order to trim memory use. Was a nice educational experience.

[upper sandal]

ah you're live !

you might have seen that come by:
https://github.com/adafruit/circuitpython/issues/6264

We are checking to see i there's a marginal timing power-up issue. We have one sample that acts like yours. Most do not, so it's been harder to reproduce.

On a few samples of Feather ESP32-S2 TFT, the display does not come on. Forcing pin 21 high in board_init() fixes the problem. This is already done in espressif_board_reset_pin_number(), but for some reason it is not working, though only on some boards.

it was on discord and the forums, I sent the person to create the issue because it needed more tests from people with the board

[inner spade]

Is it a good simple test if it’s not using the ESP32’s native networking? Otherwise it’s just a display test.

Would make more sense if portalbase would only throw a secrets.py error when the board really needs it for a network connection rather than during init.

[upper sandal]

something like

    @property
    def secrets(self):
        if self._secrets is not None:
            return self._secrets
        try:
            secrets = __import__("secrets")
            self._secrets = secrets.secrets
        except ImportError, AttributeError:
            print(
            """WiFi settings are kept in secrets.py, please add them there!
the secrets dictionary must contain 'ssid' and 'password' at a minimum"""
            )

by the way @smoky island we're here 😉

the current way is to import it unconditionally at the start of the file

yeah, that should be an exception, it would only be raised if you need the secrets

ah yeah maybe that property should be inside network

it is inited if you provide it in the init, but it could be left to None otherwise (instead of set to the imported secrets)

I believe the Network does not use secrets until you call connect() (or another method calls connect)

[upper sandal]

wait, is that a dark mode on adafruit.com ?

oh, it's a browser extension

we should ask for a dark mode on Adafruit, of all places !

he hears you talking of "bites" 😉

I'm watching him stream on youtube

[clear matrix]

I think you nabbed an old stream somehow.

[noble grove]

Topic is "CircuitPython - Making a Python Twitch Bot"

[upper sandal]

yeah on his own channel

he is looking at interfacing with a twitch bot and decided he would stream while doing it

Hello all 👋

@noble grove I don't normally stream wednesdays. But since I'm working on a twitch bot I needed to be in the chat and I think it's only active when the stream is on so I figured I'd go ahead and start it up.

[merry bear]

Q: If I'm using a LiPo charger chip like the MCP73831, do I need a mosfet or can I just hook the load to the VBatt pin / battery? The USB LiIon/LiPoly charger board doesn't use one, but the Feather does.

[tulip canyon]

Question: Do you take requests for CircuitPython libraries?

I failed converting an old BMP085.py due to GPIO vs BUSIO
Any tips?

[gusty briar]

should I try and program the esp32-s3 with the Arduino platform or the native esspressif? My project would use the ESP-NOW communication protocol and the i2s audio.

[echo canopy]

I’ve tested two C3 M5 Stack Stamp modules and it works well with ESP NOW

[brazen quail]

Hola from 'rado ! :-D

[muted mesa]

risky business, angering the pylint... 😄

[brazen quail]

Extra peachy.

[muted mesa]

hey! 👋 nice to see you too. i noticed you've been doing some Deep Dives lately. grats!

[dim wigeon]

@muted mesa If the pylint is so smart, it can go ahead and write the code for us. 🙂 Otherwise, it’s the software and we’re the programmers.

[muted mesa]

🤣 Careful... GitHub Copilot might enter the chat.

[dim wigeon]

If GitHub Copilot wants to do my work for me, I’m glad to assign it some of my Jira tickets. 🤣

[muted mesa]

*tbf, Copilot is an interesting piece of software. its the natural evolution of StackOverflow. 😄 *

[dim wigeon]

CTRL-S suspends terminal output. CTRL-Q resumes it.

(At least, on Unix-like systems with VT100-like terminals.)

[inner spade]

Yup. A somewhat outdated ANSI standard.

[muted mesa]

yeah, prob needs the raw link

@smoky island that's the RTD version. move one tab to the left

haha. indeed.

similar, yes, from what i've seen. its still in closed beta i think.

adabot was built for it. she can handle it...

[dim wigeon]

I’ve now got an absurd mental image of Adabot, Pylint, GitHub Copilot, and Siri sitting around in a bar having drinks. 😂

[inner spade]

In walks Pylint who starts picking on the others.

[dim wigeon]

I’m responsible for approving pull requests from the interns at my new job. I’ve got a healthy respect for that “approve and merge” button. 🙂

Had a merge at work today that got weird because MyAwesomeBranch and myawesomebranch are different branches to Git but not to Windows. When the intern did a “git pull” in her local repo, Git got super confused about which origin ref her branch was merging to.

(One of the reasons my work computer is a Mac.)

I’ve gotten a lot better too. But I always describe git as like a Swiss army chainsaw - very capable, very powerful, but also very easy to hurt yourself if you’re not mindful about what you’re doing.

[clear matrix]

Actually, Eva couldn't make Adabot work for updating the link to begin with. I don't know enough about Adabot to know why she couldn't do it, but apparently it didn't work.

If you're talking about what I think you were, anyway.

[muted mesa]

its because of the git patch not matching the full URL. so the diff doesn't match, meaning git believes the patch doesn't apply.

[clear matrix]

Huh. Ok. Good to know.

[muted mesa]

i had forgot about that when i made the first comment. 😄

[clear matrix]

Fair enough 😄

[inner spade]

button.name is used in examples to identify the pressed button. I use it a bunch in project code.

Nice to have something different than label, especially when dealing with lots of on-screen buttons like the calculator project with 35 of ‘em.

[dim wigeon]

I wish there was a good way to write unit tests for CPY code, especially displayio code.

I don’t do “test-driven” or “test first” development, But I like having an automated thing I can run to check that my code works.

I tend to write the code and tests in sort-of parallel.

[muted mesa]

i have struggled over that question for too many hours, @dim wigeon. the unix port for micropython is nice, but is lacking for circuitpython at times.

[dim wigeon]

Thanks, @smoky island ! The pure Python stuff is definitely easier to test than the CPY-specific stuff.

[dim wigeon]

Yeah, it’s a non-trivial problem, I think. The only way I’ve come up with to unit test the circuitpython-specific stuff is with a lot of mocking.

[muted mesa]

in the LONG LONG range thoughts, using a cam and PIL were an idea for displayio testing on physaCI/RosiePi. also, that project has languished for a couple years. it's a bit complex... 😄

[dim wigeon]

For sure. But I’m thinking about it a lot recently because I’ve been rereading the book “The Pragmatic Programmer”, which has a lot of good gems of wisdom.

A quote from the book that I actually wrote down yesterday: “Don’t program by coincidence. If you’re not sure why it works, you won’t know why it fails.”

[muted mesa]

i haven't read Pragmatic yet. is that one of...David Beazly's book? i know of it, just forgot the author.

[upper sandal]

if you have a code base without unit tests, you can start by writing a test every time you work on a bug, helps test the bug anyway, and the test stays for later

[dim wigeon]

@muted mesa : Dave Thomas and Andy Hunt. The 20th anniversary edition is REALLY good.

[muted mesa]

ahh. yeah. its on my long list of books i procrastinate reading. 😄

[dim wigeon]

And the Audible audiobook of it has the narrator cast in the persona of “the book”. So she’ll occasionally say things like “I’ve skipped some of the setup code in this example. I’m a book, not a programmer.” 😄

Good morning Tim and everybody present!

[inner spade]

[modern night]

Hello all! Hope your day is going well

[upper sandal]

hiiiii

I'm trying to understand the issue with CGrover's PR to the bundle, and I'm not sure I get it 🤔

[inner spade]

I’ll take another stab at it based on @smoky island ‘s observation.

[upper sandal]

that's not an issue though, we have that all the time

[inner spade]

Is the version tag compatible?

[upper sandal]

I think its more precisely that the commit added to the bundle is not the tagged one

the version tags are expected to be semver

that's 1.2.3-beta.0

so, not with the "v" in front

[inner spade]

Ah. Drop the v.

[upper sandal]

update-submodules.sh should checkout the latest tag in every module

when I make sure I have that, build.sh seems to work locally and include cedargrove_nau7802.py

I don't know what the CI check runs though, I don't know if it checks out the latest tag or goes with whatever the repo points to, which is a little mysterious in git

[inner spade]

Thanks. If/when I get this to work, I’ll submit a revision to the instructions so that neophyte CircuitPython/git users can more easily contribute.

[upper sandal]

yeah, information about the version is in the "release to github" section of the "sharing a library" guide, but most of it assumes that you used cookiecutter too

[inner spade]

@smoky island thanks for including name as a property. Looking through my code, I used it in every project.

[upper sandal]

your library for example is missing that line that circup uses to know the version (and is filled by the bundle release script with the git tag, that you can get on your repo by using cookiecutter to have a library zip and mpy in your repo)

__version__ = "0.0.0-auto.0"
__repo__ = "https://github.com/CedarGroveStudios/nau7802.git"

[modern night]

would this be a good place to use kwargs?

[upper sandal]

yeah it's just seems assumed in some places

[modern night]

This is stretching my python knowledge, but can't you say a function takes in some kwargs, then in the function see if one of the inputs was 'label_font' and handle it there, that was the function definition doesn't need to take in every possible kwargs?

The second example in this section kind of does what I was thinking: https://www.listendata.com/2019/07/args-and-kwargs-in-python.html#id-7223dd

I know a lot of scikit-learn functions have inputs managed in that fashion. That said I don't know how to typehint those

[upper sandal]

why do you need Button in Base ?

ah I get it ok

you could put base in a submodule

no I mean a button_base.py file

submodule in the python sense, not the github sense

yeah portal_base is confusing

though I would argue that here they are in the same library, and would be in the same docs page for example

[modern night]

that's a good reason! I just wasn't sure if you were fighting pylint on it, and it'd be a way around that. But for doing it clarity's sake is a great reason

[noble grove]

If they are redundant you could make it a comment.

[proper prawn]

Still power lines above ground huh?

[upper sandal]

what I was saying earlier is that ButtonBase could be in its own file, not in __init__.py

don't disable, just put the class in another file

you can put it back at the top then

well yeah the reason it failed was because of cyclic imports

[inner spade]

@upper sandal @smoky island Appreciate your help with the community bundle PR. Going to refactor it using cookiecutter and toss my stubbornness. It’ll be good for me and saves the cost of hiring a Python intern. 😏

[upper sandal]

right, I am surprised that it even works by putting the import at the bottom

[proper prawn]

I have to run... have a fine weekend all!

Thanks Tim!

[modern night]

you can always pylint ignore for now, and come back to it in the future. Clarity is a good reason for the time being

[upper sandal]

yeah make it ignore

[inner spade]

Label color None, perhaps?

[modern night]

I have to head out. Thanks for the stream, it was really helpful to work alongside of!

[inner spade]

[inner spade]

You have to output to a column in order to read a row or visa-versa.

Can you just use the keypad matrix mode?

Set a row to high or low

While inputting from a column

🎉

[upper sandal]

you want pull True if there's no hard wired pull

[inner spade]

The display should work from 3.3v pin

Raspberry pi example uses 3

SCK to clk

MO to DI

[upper sandal]

SCK stands for sclock

[inner spade]

board.Dx to CS

[upper sandal]

(that was a joke "sck -> sclock", but yes SCK is the SPI clock)

[inner spade]

MO is MPU output

You’ve got it wired correctly

CS is usually inverted

You shouldn’t have to change it

One of the examples just used board.Dx in the instantiating statement rather than predefining it with DigitalInOut

May be clock speed sensitive

Try baudrate of 2MHz

wiring one up to a Feather M4 now...

I'll try it along with ya

[upper sandal]

circup update does not install new libraries (or dependencies)

yeah analog ref

[inner spade]

I have it working on the Feather M4 at 8MHz

[upper sandal]

on NRF you can use that to set the analog... reference... never used it, I believe it sets what is considered V max so you can set it lower for better precision ?

or just for comparison

no they are not the same, the pink one is 500% more awesome

[inner spade]

and it works fine if the display power is connected to USB (5v)

on the Feather M4

ran the one from the tutorial

circuitpython displayio usage in the learn guide

framebuffer = sharpdisplay.SharpMemoryFramebuffer(bus, chip_select_pin, width=144, height=168, baudrate=8000000)

[upper sandal]

yeah discontinued https://www.adafruit.com/product/1393

[inner spade]

Can't find a reference for the kwargs for the SharpMemoryFramebuffer class. Wondering about reversing the white-on-black.

Sometimes the driver can check register contents, depending on the manufacturer's power-up default register settings. Seldom have I found repeatable and unique settings other than version -- which isn't all that unique.

I'm going to put this display back in the drawer and pour a cup of coffee.

[upper sandal]

I had a semi panic about a tri-color e-ink display not working and displaying garbage, turns out the width and height were swapped even though I was using the guide code (or at least I think so)

great Lars pun there too

lars is tweaking

i have some DVI-I DVI-D monitors

[grand tusk]

Thank you.

[viral sail]

Thanks @haughty quiver

[shell mason]

could be interest to have DVI monitor to give cable what then transfer to HDMI

[inner spade]

Thanks! At that price it’s almost free.

[cinder wind]

Woo!

@inner spade right? it's probably costs the same just to get an HDMI jack 🙂

[shell mason]

great one

dinner time! great job hosting @hard hollow && @rocky reef and always great to see what you're working on @robust horizon

[tulip canyon]

Thanks everyone

[slow spire]

@tight bridge Try again next week; there's a signup somewhere; don't know why it was a short show

[hard hollow]

thanks for tuning in folks!

[open surge]

Thanks all, good show

[rocky reef]

awesome projects folks!

[lilac tusk]

Ohh I missed show n tell whoops

[open surge]

@tight bridge signup happens a few minutes before the show in live-broadast-announce - look for the Streamyard link to join in

[robust horizon]

I just love this QR code, sized to fit on the pygamer/pybadge screen

here's the blog link about the qr codes: https://blog.adafruit.com/2022/04/26/a-python-qr-code-generator-that-can-also-do-color-animated-codes-python/

[split gazelle]

love the totoro one

[robust horizon]

the servo motor stuff is in the newest circuitpython prerelease, check it out! https://github.com/adafruit/circuitpython/releases

and here's the case, original version stl files & freecad design files: https://www.printables.com/model/171159-pygamer-lanyard-case

[smoky island]

Oh, those QRs are lovely, I went down the rabbit hole of making some of those fancy ones many years ago. Amazing to see a generator for them

[tight bridge]

So how does one get on the show, Adafruit has been very helpful in the development of this project

[slow spire]

Here's one I did of me.

[robust horizon]

huh discord doesn't want to display that file, it's formatted for circuitpython as a bmp. try this one

[smoky island]

In this channel a few minutes before showtime they will post a "stream yard link" lick on that and it opens up a webpage that has the camera / screen share options.

[slow spire]

See @open surge 's post above

[tight bridge]

Thx, maybe I can be ready for next week

[open surge]

Yup, just look for the Streamyard link in this channel 5-10 minutes before the show

[slow spire]

Cool. Checked out https://adminboxx.com, and looking forward to seeing a demo!

Love the 15 sec promo vid for Adminboxx!
https://www.youtube.com/watch?v=G-FYu7ic4sc

@tight bridge Demos are about 2 minutes on Show and Tell; My first question was: Is this for real racecars? for RC racecars? And then I realized it's for PC racing games, right?

Some prerecorded video of someone using it might be nice to talk over during your show and tell

[tight bridge]

Yes, the board is a bit overkill for what I am doing, but the form factor was perfect. getting the pads printed was also interesting. BTW, it is not a game, a simulator. Drivers are too serious for it to be a game and the money!! 🙂 🐟

[slow spire]

Interesting

Would love to hear about how you did custom keycaps, both in prototypes and finished product. Gorgeous.

you scolled past a pdp 11. I programmed one of those in high school in the 1970s

[grand tusk]

ooh, papertape

[slow spire]

PAPERTAPE!!!!!

I am so old I actually used paper tape in school.

This is frickin marvelous. Wish I had been in the area.

[ionic garnet]

I did too in college. In high school I had to program in binary through the toggles on front of pdp 11

[slow spire]

Ooooh dial phones and electromechanical switching

[turbid hill]

There is a phone museum in California that has big full blown old exchanges, just huge stuff.

10% discount code, code is: QTPYPiCO http://www.adafruit.com

[slow spire]

Fun fact: Unlike the Pi-hole, the ESP-hole prevents advertisers from reading your mind.

[hollow temple]

Sometimes, I wonder if these code creator software teach anyone anything. Seems that kids who use them seem to not have a full grasp on programming. But only how very specific 3rd party libraries work, that take all the programming out of programming. They don't know how to program they know how to use software. Sorry to be the bearer of constructive criticism but if I meet another kid who can program in node, python, or whatever package, and can't write simple html or assembly. That never changes is frustrating because experienced doesn't mean experienced anymore

[open girder]

@hollow temple a lot of the time it's to help get young folks started, the first experience, getting started fast, and making a project

[nimble jackal]

The solder never gets old

[waxen thistle]

Good evening all you most excellent & wonderful makers!

[hollow temple]

Ya I get the idea, but it doesn't help in a production env, when kids have been using packages for 3 years. Still can't write basic html or convert hex to bin.

[grand tusk]

so many feathers

Windy day in NYC.

[urban gale]

I love those testing rigs. They give me ideas

[waxen thistle]

You can see Tatooine from your pick n' place!

[hollow temple]

Gotta build a software that goes from beginner to advanced in the same software. VSCode is getting better its easy to get set up in multiple languages

[waxen thistle]

There's something so appealing about quality test jigs. Single purpose, high quality, transactional design. If it's worth doing, it's worth overdoing....

[green bison]

Can you explain the last bit to my boss?

[neat aspen]

I've been spending the week teaching kids Tinkercad, and I think that anything that sparks curiousity is a win. I don't care that they don't 100% understand the layers of technology their projects are sitting on top of. The ones that are sparked to dig deeper will -- but if you can't get a spark if you set up a ton of barriers to getting started.

[open girder]

@hollow temple a lot of young folks are using vscode, or at least, we're seeing then use it a lot 🙂

[waxen thistle]

Joke's on them.... "What mind?" 🧠

[urban gale]

"If it's worth doing, it's worth overdoing" Whoa! I say that all the time too!

[waxen thistle]

After two days of cleaning up storm damage, my brain is on the level of "fire bad, trees good."

[fallow fractal]

a commodore 64 sounds like a good idea if you want to play game and can't afford a car priced graphic card

[hollow temple]

Ya it took me 10 years to change software than I was forced into VS Code but its not so bad really, because come to find out It's More like Eclipse, Java, VS Studio, and Adroid studio, and Ming all in the same software

[fallow fractal]

the best games ever made were on amiga/c64 back then...

[waxen thistle]

The corollary -- if it's worth doing, it's worth doing poorly.

[taking action matters. it's better to do a little bit of something than a whole lot of nothing. Can't exercise for 2 hours? Then taking a walk around the block is better than sitting for the entire day.]

[fallow fractal]

depends where you sit

if you sit in a spacecraft I'd say you will do a lot of sports built-in when it lift off

[slow spire]

I've used Eclipse, Xcode, Codewarrior, VSCode, Arduino IDE, Mu, MakeCode, and probably a few more, and I expect to be learning new IDEs for a while.

[fallow fractal]

I'm like a cat with IDE. I hiss loudly if you don't give me the correct IDE

[hollow temple]

I would just assume write in notepad like the old days, less distractions

I know I had to write the code, not search for a plug in

[slow spire]

Yeah, I use Atom a lot.

[waxen thistle]

Atom, VSCode, Sublime are three of the more popular customizable code editors....there's lighter-weight ones like Mu, Vi(m), and emacs.

At some point, it doesn't matter which tool you use -- just as long as you're creating something. There's enough overlap between core functions to get work done.

[hollow temple]

I taught a kid how to use an arduino in 2015, now he's like satoshi nakamoto.

[waxen thistle]

It's nice this company is giving so much useful information for emulating a human heart errr I mean, for measuring our heart rate.

[hollow temple]

I could make an alarm that posts onto facebook to let everyone know that my heart has stopped...

..... Just rebooting

[fallow fractal]

do they ever answer during ask an engineer ?

seems so pre-taped

[turbid hill]

you could do what jay2cents did which is tie a pulse monitor to himself and have it on screen whil he twiched himself playing horror games

[open girder]

@fallow fractal we're live

we'll do the questions during the show/at the end and more

[fallow fractal]

pulse monitor aren't good enough for that

[slow spire]

@fallow fractal It's completely live, but they get to questions at the end of the show, and they need to be questions that don't need a 20-minute answer.

[fallow fractal]

can be stopped by a thin film on the finger

[slow spire]

@fallow fractal Do post your question, in the form of:
Question: ........

[fallow fractal]

so they aren't considered accurate or generally reliable/indicative of anything but they can help to reassure the patient as someone said

I mean the ones muggles can buy of course

[waxen thistle]

They're live -- they answer questions near the end. If you have a question, go ahead and ask (helps to @ adafruit and prefix it with "Question:" to get their attention).

Many times a question is asked and gets answered by the community before they can get to it 🙂

[cinder wind]

don't poke the pt. who knows what could happen

[fallow fractal]

an oximeter is usually the first thing they plug you on in hospital and their is a much much higher grade

checks if there are chips that can do defibrillator to plug to the oxymeter chip

[waxen thistle]

"Hospital grade" is very much a thing, and commands an appropriate price too.

[slow spire]

@fallow fractal, yes, we know that Masimo and other medical-grade sensors are quite good. But one can learn a lot by playing with less expensive sensors.

[green bison]

The FDA explicitly does not play

[slow spire]

New products!

@fallow fractal Now would be a good time to post your question.

[waxen thistle]

These sensors are considerably less expensive, and allows the maker community to achieve similar results -- as always, be cautious when DIY'ing tools in a potentially life-saving capacity.

[fallow fractal]

I already did, I was wondering if it was actually live 😄

[waxen thistle]

Oh those pogo pins are nice.

[open girder]

easy question 🙂

[desert orbit]

I like that that cam's name is "Frank" 😂

[waxen thistle]

We have Minnie (MIDI), Jason (JSON), and now Frank!

[slow spire]

@fallow fractal I can't find your question. Oh wait, now I get it. 🙂

[fallow fractal]

I forgot it but someone asked one I'd like to know too

[desert orbit]

the PPK is awesome, didn't notice you guys got more in stock! was hard to find for awhile there

Now you can put the whole arcade machine inside an arcade button

[waxen thistle]

You can put the whole arcade inside the arcade button....with room to spare.

[echo canopy]

Question @open girder

Some time ago, I thought I heard you saying there was a project to have Arduino sketches behave similarly like Circuit Python to where you could drag not only code but extras like a MP3 files over to a board such as an ESP32 (xx)

Is this something still in the future? Or workarounds or is SD Cards the way to go ?

[ionic garnet]

Oh thank you for this pinout

[fallow fractal]

Do you answer the questions from youtube? Someone asked one and I'll copy it here because I want to know too

[open girder]

yah, we try to get to those too

feel free to post it up here too, all good

[waxen thistle]

Nothing wrong with posting a duplicate (or a second time if you posted it a while back)....

...posting it 27 times? ehh not so much 😉

[desert orbit]

q: Have you worked with the HX711 load cell amp/ADC before?

I've been working on a project with a pile of 25-cent Aliexpress HX711 boards (made a CPy driver for it, coming to community bundle soon!) and it's pretty dang useful for how inexpensive it is.

[fallow fractal]

ok I give up

I'll put my uno in the garbage 😦

[waxen lava]

Question, the PN532 shield doesn’t read w adafruit Meteo ESP32-S2. Any plans for integration? Am trying to make a wifi connected RFID reader

[turbid hill]

Q: is that cube matrix you showed held together via magnetic's

[desert orbit]

ok! will do 😄 thanks guys

[slow spire]

I think Adafruit's working on a NAU7802 sometime in the future.

[modest ingot]

Question @open girder I've got a pm2.5 STEMMA air quality sensor working with a raspberry pi, but when I I try to connect it to the ESP32-S2 QT Py I get an error. what's the best way to open a bug? I posted on the help-with-circuit python discord channel, but not much luck on an answer yet.

[waxen lava]

Thanks!

[cinder wind]

magnets? how do those work

[turbid hill]

it's magic

[modest ingot]

thanks

[slow spire]

Try also posting on https://forums.adafruit.com, possibly.

[grand hull]

Question: Did the education at M.I.T. help on the manufacturing, business & logistics aspects of Adafruit or was it through the “School of Hard Knox?” Impressive work by you and your team!

[desert orbit]

nice, I was looking at that one and it's a good chip. nice to have I2C for sure, ❤️ stemma-qt 😄

The HX711 just seems to be massively ubiquitous though, it's all over the place for dirt cheap, at least in breakout form. Its not I2C but its serial protocol is super simple and really timing-tolerant.

[ionic garnet]

agree about some good content on YT

[waxen thistle]

One of the most relaxing ways to pass time -- I turn on a DIYer in the background who repairs Kitchenaid Mixers. It's surprisingly soothing.

[turbid hill]

kizard or something

[waxen thistle]

Thanks @open girder for another excellent evening of shows!

[ionic garnet]

thank you for all you do @open girder

[slow spire]

NAU7802 is available in some quantities lately; there are also breakouts; I know Sparkfun has one.

[cinder wind]

Thanks, Limor & pt!

[slow spire]

HX711 is great until you try to source it on mainstream distributors like Digi-Key or Mouser.

Thanks, @open girder

[desert orbit]

oof, yea, good point. Seems like one of those chips you could buy by the bucket in a Shenzhen market, but that isn't a sustainable model for manufacturing 🙂

[slow spire]

For example, here's a search on Octopart:
https://octopart.com/search?q=hx711&currency=USD&specs=0

[desert orbit]

I wonder where Sparkfun sources it from? Hmm

[slow spire]

Exactly. And good luck getting a quick trip to/from Shenzhen at the moment.

[desert orbit]

mikroElectronica, Seeed, DFRobot, M5Stack have done breakouts too. Once I'm done learning how to use the template to build a community driver I'll probably grab some popcorn and try and learn the story of the HX711's life 🍿

[slow spire]

I've purchased HX711 breakouts before. Looking forward to something that uses I2C.

[desert orbit]

yeah, I2C is definitely easier. My motivation for writing a proper community bundle driver was basically that the maker world is already flooded with the darn things, so they may as well be ready-to-go with CPy 🙂

also I had a pile and wanted to play with RP2040 PIO, which was actually perfect for the HX711

[slow spire]

I'd say go ahead and do it! If you haven't before, here's a good start:

https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library

[desert orbit]

I'm so glad that the team took the time to write (and maintain) that page. Made it really easy for me to make the jump from "oh, neat, this works nicely..." to "oh, hey, it doesn't exist in the bundle, lets fix that".

[slow spire]

@desert orbit https://www.digikey.com/htmldatasheets/production/2071114/0/0/1/hx711.html

Includes sample C code.

[desert orbit]

yep, that's the one. 🙂 Spent a lot of time with that datasheet over the last week

after spending a month refactoring the ADPS9960 driver for fun a few months back... the HX711 was a breeze 😂

[slow spire]

Cool. Certainly would be nice to have a CP library for that, since it is so widely available!

I have a pile of those myself.

Along with strain gauges and load cells of various sizes and qualities.

[desert orbit]

nice, I figure it's lurking in many people's stockpiles

Just added more load cells to my cart before putting in my ESP32-pico QT Py order 🙂 Plenty in stock at adafruit at a fair price! 😄

[slow spire]

I needed a small load cell for a prototype one time, which is how I ended up in a head shop on Maui. 🌴

[fallow fractal]

you guys know of a video showing all of the adafruit cardboard construction stuff ?

[slow spire]

@fallow fractal I know Ladyada has demoed it on AAE before

There are typically videos attached to the product pages. Try these:

[green bison]

Gah I had a question after AEA. Does anyone know why the adafruit 12 neopixel ring schematic says WS2811 while the product page says 2812B (Or another model)?

same footprint?

[noble grove]

QUESTION: Can the hardware TX and RX pins (D0 and D1) on the KB2040 be swapped? (transmit out of the RX pin and receive on the TX pin)

[robust horizon]

@noble grove no, the hardware UART is not capable of performing the swap. However, the pico-examples shows how you can use a PIO peripheral to do UART RX and TX, so you could potentially do it that way.

[robust horizon]

Lars's cousins are at the airport

[sudden slate]

Can't recall - is there a workshop today?
