I keep reading that as "tofusensor"

[open girder]

@sterile forge it happens, there is a global part shortage

we'll try and have more in stock next time

[sterile forge]

That 's cool

[echo canopy]

Question @open girder How far out is the ESP32 Itsy-bitsy? Just checking have a project in mind … Thanks 🙏🏻

[analog acorn]

Question: I designed a RPi-based system to display distance, for my friend to use backing his boat into a slip. Is there a way to waterproof a ToF sensor?

[turbid hill]

Q; How is the flooper duper board and feather hat going when will you have them in store

[inner spade]

Question: Would it be useful to apply PrettyPins to breakout and featherwing boards in addition to MPUs?

[tulip canyon]

🖐️

[echo canopy]

WOW so many orders … high five 🙌🏻

[analog acorn]

I feel called out on that one of everything comment.... 😉

[turbid hill]

Lol I have lots of different ones also

[analog acorn]

Nice! Thank you!

[upper sandal]

any news about the Rev C of the QT PY ESP32S2 ?

[glossy basalt]

What would you suggest as your best learning sources outside of the guides on the site? Any names/sources come to mind?

[alpine radish]

What are you trying to learn?

[turbid hill]

Great scott is also a good channel to watch

[eager matrix]

Are you going to do any IoT things with Thingsboard. It's open source and can be self hosted and it is pretty awesome esp with the dashboards that can be set up.

[alpine radish]

Seriously -- the best way to do it is to find a project you're excited about and work towards it.

BTW -- I don't always have time to hang out on Adafruit. But I love every minute of it when I do.

[echo canopy]

Great Show

[river hemlock]

Yes, thank you!

[analog acorn]

Thank you for the show, team!

[upbeat coral]

Thank you for giving us your time.

[alpine radish]

Woohoo!

[ionic garnet]

thanks folks. See you soon!

[viral sail]

https://www.adafruit.com/product/5325

Please note there is a hardware bug in the current revision of the PCB that causes deep sleep to draw ~6mA, if you need ultra low deep sleep current please wait till rev C is available (it is not yet, no ETA).

Waiting for John in 1/2 minute. 😉

[haughty quiver]

[inner spade]

Waiting in 500ms.

[lavish patrol]

Greetings, all.

[drowsy inlet]

hello all 👋

[lavish patrol]

Waiting for Lars in - who knows. 🤔

😄

Bleeps and Bloops are imminent. 🎶 🎵

[spiral vale]

almost forgot!

[haughty quiver]

[lavish patrol]

Lol

[spiral vale]

breakbeat looper == blooper

bblooper

[open surge]

/wave

[midnight plinth]

Yay, music and John.

[lavish patrol]

Look at Lars. 😄

[spiral vale]

(although there's already a pedal called Blooper - so thats a no go)

people are here

[cinder wind]

are we here? I dunno. I'm not here

[spiral vale]

🤖 are here

e are where?

[ionic garnet]

Hey peeps

[lavish patrol]

This is a virtual world...

[open surge]

perfect timing for positioning, I need to learn this for a project

[cinder wind]

ooo that's pretty cool

[ionic garnet]

displayed pretty smooth even over video

[drowsy inlet]

is 0,0 top left?

[open surge]

yes

[ionic garnet]

yes

ooh, you beat me to it

[drowsy inlet]

thank you for the additional demo

[smoky island]

worth noting also, that the Circle shape is anchored by it's center point rather than top left corner like Rect and RoundRect.

You could use it for games. I think I made a very primitave pong with it at one point.

[open surge]

cool, thanks john!

[ionic garnet]

that's what the movement of the rect reminded me of. It looked like early pong implementations on monochrome monitors

[inner spade]

Vectorio is a bit faster (for solid shapes — no outline yet).

[smoky island]

There is a basic pong implementation documented here: https://hackaday.io/project/168623-pybadge-single-player-pong that uses shapes and movement similar to what JP showed in the parsec.

[ionic garnet]

@cinder wind recently discovered your github tips and tricks page. Very helpful! Thx

[cinder wind]

awesome! glad it's useful. I use it every time I use CirPy because I always forget just how to read a pot haha

[ionic garnet]

M4 nice. Fast floating point

[ionic garnet]

Exactly.

[open surge]

Tod will be talking about that on The CircuitPython Show podcast in a few weeks, too. 🙂

[spiral vale]

A "break" if you will

[cinder wind]

160 bpm because everything is drum-n-bass even if it's not

bwaa haaa haa

[rotund marsh]

@cinder wind cheers for https://github.com/todbot/circuitpython-tricks

[ionic garnet]

Funny. First thing I spot on every CirPy code (including my own) is pixels.brightness = 0.1 (or less)

those little leds are bright so 0.1 is a nice setting

[inner spade]

Audio levels okay

[ionic garnet]

more cowbell

[lavish patrol]

🐮 🔔 😉

[cinder wind]

woohoo esoterica!

[ionic garnet]

love the list comprehension

[shell mason]

the phone looper could be cool with that

[cinder wind]

I don't fully understand Python set() that is used in the Trellis M4 example code. I first saw it here: https://learn.adafruit.com/adafruit-neotrellis-m4/adafruit-circuitpython-trellism4-library#width-and-height-can-make-rainbows-3008063-30

[drowsy inlet]

looks like maybe it's being used to determine which keys have been released?

[ionic garnet]

it's creating an instance of set() which is like list but may contain only one of any given element

[drowsy inlet]

for release in current_press - pressed

sorry, you don't understand set or how it's being used?

[cinder wind]

I don't like it

hahaha

is what I really mean I think

[ionic garnet]

now we get to the crux of the issue

[drowsy inlet]

yeah, looks like it's being used in lieu of bitmask

[cinder wind]

a bitmask would be so much more efficient than an entire collection that set operations are done on

[drowsy inlet]

agreed

[ionic garnet]

yes agree

[shell mason]

trellis with beatboxer

[cinder wind]

ahaha that's awesome!

[drowsy inlet]

this is so cool

[clear matrix]

That one's on me. I don't know how to do bitmasking. Looks like I wrote that example, so it kind of makes sense that set was used.

[cinder wind]

it seems a very Python way of doing things. but I'm an old crotchety C programmer

[clear matrix]

Also, I wrote it 3 years ago.... So........ WAY more experience now.

[clear matrix]

That's fair. 😄

[drowsy inlet]

yeah, bitmasks don't feel pythonic, imho

[cinder wind]

btw all these samples except for amen break are from freesound.org

oh I understand that trellis keypad code more now. not dumb! very smart

yeah look at all the uses of Amen, Brother that have been cataloged https://www.whosampled.com/The-Winstons/Amen,-Brother/sampled/

[ionic garnet]

Very cool stuff. I have a couple of those trellis kits around that need a home

[drowsy inlet]

would make a great JPPPotW 🙂

[cinder wind]

Trellis M4 also really good as a macropad.

[rotund marsh]

Macropads are so 2021. When are we building metaverse interfaces?

[lavish patrol]

Thanks, @haughty quiver for another great workshop. 😀

[ionic garnet]

Thanks @haughty quiver . A great episode

[midnight plinth]

Great meeting, thank you John.

[cinder wind]

[haughty quiver]

Fun Amen Break usage to go back to: George Michael's Waiting For That Day

[smoky island]

@haughty quiver have there been any parsecs featuring displayio Label usage? There may be some opportunities with them if not.

[haughty quiver]

Hello you lovely Python people

[grand tusk]

Greetings all.

[ionic garnet]

We got about 8" of snow overnight here in Massachusetts

but it was 70°F 3 days ago

welcome to New England

[grand tusk]

Pull out the snowshoes.

[eager matrix]

Hi Scott. I did the same 5 minute thing but I just sat by the window and let the sun hit my face.

[fresh blaze]

'ello folks.

[odd zodiac]

Hi all.

[ionic garnet]

'Ello!

I lived in Seattle briefly

kind of

[smoky island]

Happy unofficial beginning of the weekend to everyone! 👋

[ionic garnet]

I loved in Beaverton OR but had an apartment and spen weekdays there

[inner spade]

Hello everyone!

[ionic garnet]

I like the snow

[nova totem]

Hi everyone. If anyone wants snow I have 6 feet in my yard

[ionic garnet]

I lived half my life on east coast, half on west

both are great

[eager matrix]

My other sister (not the circuit python one) lives in Seattle. You may have bought cheese from her.

[dim wigeon]

Hi everyone!

[ionic garnet]

in Seattle I meant. I lived in Beaverton but went to Seattle for weekdays

[dim wigeon]

Scott really doesn’t like the fact that he can go to snow; he likes the fact that he can LEAVE the snow and come home. 🙂

[fresh blaze]

30C and thunderstorms here a little later this week. I just might like a visit from snow

[dim wigeon]

@fresh blaze I know those feelings. Summertime here (Arizona) is when we get the super special “50C and pouring rain” days 🙂

[fallow current]

Hola from fresh powder in the mountains of 'rado ! 😄

Is it true Zynq is in the running for baby names ?

[ionic garnet]

yes warm

[dim wigeon]

How about Blinka?

[eager matrix]

Can you say some words about your shirt? Is that xkcd?

[ionic garnet]

any good examples of interrupt usage in CircPy?

I thought there was new support in the latest stuff. My mistake

got it

I use C++ when I need interrupts anyway

[dim wigeon]

I imagine “it’s better to fall further” is true within limits… 🙂

[ornate coyote]

Have you been practicing with you tablet?

[eager matrix]

@ornate coyote Hi. How's it going?

[ornate coyote]

Hey @eager matrix - doing good, you? About to start PnPing more ProS3s...

[timid plover]

thanks for the links last week to the Ben Eater USB videos https://www.youtube.com/watch?v=wdgULBpRoXk&ab_channel=BenEater

[sterile forge]

I was trying to understand the difference between Host and Perphrieral devices.

Periphrial is from a device to the controlller and Host is from the controller to the device. The USB UF2 bootloader has both but Tiny USB only provides the Periphal side of things to CircuitPython, is that right?

Also there is a difference in the enumeration process, ithink.

[ionic garnet]

I have two LG 32" UHD monitors but have been considering an ultrawide instead next upgrade

[dim wigeon]

So how does collision detection work on a USB bus? Do the devices just not communicate until the host asks it for a data packet?

[clear matrix]

I'm running 2 x 34" ultrawides. There's a lot of display going on here.

[simple fractal]

Yes i had two 34's before, the middle bothered me. so now its one. and i gave the previous ones away

and with my eyes super high res was a no go.

[timid plover]

I thought that USB 3 might allow a non-polled peripheral ??

3.0 is new to me too

[ionic garnet]

same here. I will be 60 this year so no tiny text. But I like the clarity of the display for movies or video

[simple fractal]

i believe usb 3 simulates polling,

[ionic garnet]

what is this concept: a boook?

me too

I have 100 coworkers in Ukraine. Hoping they are ok. No politics, just well wishes

[sinful meadow]

good morning! missed the start

[simple fractal]

just started sort of

[timid plover]

this was the phrase "In USB 2.0, the host controller polls the bus for traffic" that drove my mis? understanding 🙂

from https://en.wikipedia.org/wiki/USB

assumed maybe there was a change ?

[simple fractal]

"USB 3.0 suspends device polling, which is replaced by interrupt-driven protocol."

and as nothing we are using is usb 3.0 doesnt matter. probably.

[ornate coyote]

@rapid hornet my original ProS3 design had PD on it, but I couldn't get any chips - and re-designed 3 times and then gave up and took it off.

[eager matrix]

Things here are good. The events of the world are really weighing me down though.

[simple fractal]

a nice discussion about usb 2.0 protocol https://www.beyondlogic.org/usbnutshell/usb4.shtml

[ionic garnet]

You can get them for $100+ (Pi 4)

[eager matrix]

I'm working on project for an artist and I need a bunch of Pi Zero 2 W boards and I'm waiting for stock.

[digital crescent]

https://rpilocator.com/

[balmy tinsel]

that gives you something to add if you ever decide to do another revision of the board

[ornate coyote]

I wouldn't do a revision... I'd just make something new, but yeah, would be ace to have have a board with PD.

[sinful meadow]

blinka is also using pyusb (via pyftdi)

[ornate coyote]

No room on the ProS3 for more IC's anyway 😉

[simple fractal]

yes, PD would be nice. but next new thing to attract us 🙂

[eager matrix]

Thanks. I didn't know about that. I've been using Octapart but it doesn't include a lot of what rpilocator has.

[ornate coyote]

I thought things might have turned around, as some of my parts became available and at reasonable prices... but speaking to other folks they seem to think it's getting worse 😦

[sterile forge]

endpoinnts allow multiple devices to be one (ie the raspberry pi keyboards which have a hub included,

[ionic garnet]

many factors: Covid-19, shipping backlog/container ships, backlog of fab upgrades

[digital crescent]

do you have a microcenter by you?

[eager matrix]

It depends what you are looking for. I've had pretty good luck getting STM processors.

[turbid hill]

whooo almost missed the dive

[ionic garnet]

in CTO speak, we call that "a confluence of factors..."

[clear matrix]

Does Micro Center have them in stock? I ended up getting two Pi 0 Ws (v1) from someone else for an upcoming project because I didn't think anyone had them in stock.

[turbid hill]

Pi stock at the moment is really bad, Raspbeery has stated they should be a bunch showing up in march

[clear matrix]

It doesn't need a 0 W 2, so it's fine. But still, worth knowing in case I need more later.

[eager matrix]

Higher end new stuff.

Hi @clear matrix

[ionic garnet]

new, new, new,... You have to sing it!

[turbid hill]

Remember when ever buying these microcontrollers always get 2 of them

[digital crescent]

I could be wrong, but I think they get them and don't list them on their site.

[clear matrix]

Sounds like something they'd do.

[turbid hill]

All is ok as long as FedEx doesn't decide to land on your lawn.

ctrl plus wheel scroll

lol

yes my poor aged eyesight thanks you

[warm pulsar]

@ornate coyote Hi Seon. Got my Unexpected Delivery today! Wasn't really unexpected 🙂 Thanks

[turbid hill]

@ornate coyote My package is here also although I should remember to double check my address so I don't get it delivered to the wrong post office.

Is this all C or mix C/CPP my C/CPP is real rusty

[sinful meadow]

all C

[turbid hill]

Ahh

The // instread of /* */ throws me for a loop

Oh interesting

[sinful meadow]

C got single line comments in c99

[ionic garnet]

neat

[ornate coyote]

So silicon is getting worse, but mail is getter better - that's half a win!

[turbid hill]

Does not teachers at school emphasize lots and lots of comments in code.

[ionic garnet]

I use sublime merge on Mac

[sterile forge]

Composite devices was the term I was looking for

[sinful meadow]

//set x to 1

[ionic garnet]

There has been an anti-comment movement in coding standards. But I agree with this philosophy

[simple fractal]

https://www.git-tower.com/blog/diff-tools-mac/

[eager matrix]

Beyond compare is awesome. I send them an emeil every once in a while to let them know how uch I like it.

[upper sandal]

there's FileMerge packaged with XCode, can be called from the command line with opendiff, I use BBEdit and its command bbdiff usually

[ionic garnet]

Readability is massively important

[turbid hill]

That is a good way of doing it

I like google idea

[warm pulsar]

If you need to comment your code to convey the meaning of the code, it's not clear code....

[turbid hill]

I think I will mention it at work

[grand tusk]

CircuitPython has helped me write better Python code.

[simple fractal]

i remember having arguments about comments like 'add 1 to variable'\

[warm pulsar]

If you need to comment to explain non-code reasons why something is done this way, then ok. (doing this lowers power consumption...)

[ionic garnet]

I mostly agree. But there is going to be some mystery code especially when dealing at systems layer

[eager matrix]

A friend of mine told me a long time ago commenting your code is a way to not get stuck doing the same project forever. You need to be able to hand off your code.

[simple fractal]

i generally would comment about what i wanted to do. and let the code flow

[grand tusk]

pre-commit in particular.

[ionic garnet]

yes. True in all aspects of your career. Always be sure someone can take your job so you can move up

[digital crescent]

or down

[simple fractal]

my (few) PRs that i did to tinyuf2 did help me. thach is very picky about code 🙂

[ionic garnet]

right

or out

[eager matrix]

or just something different.

[ionic garnet]

Absolutely. This is still a common misconception among many programmers. There is little value in being a single threaded bottleneck in any project or process

[upper sandal]

yourself 1 year from now is someone else

(or 2 months for that matter, I'm a goldfish)

[warm pulsar]

yes, handing over a project to your future dumb self is quite important...

[ionic garnet]

got to take Bella (doggy) out. brb

[inner spade]

My philosophy has always been to “work myself out of a job.” It worked nicely a few times during the career.

[turbid hill]

I looked at some C code I wrote 20 years ago and oh how did I write that, I had to think about it.

[ornate coyote]

I'm def the exception to the rule - I'm 100% the bottleneck and always will be 😉

[clear matrix]

The first time I did git blame and it was me, I was super excited. Achievement unlocked! I had finally written enough code to have forgotten about something I wrote.

[simple fractal]

my friend hates when he sees some code i had written with the C ternary operator.

[warm pulsar]

either or both?

[eager matrix]

Are peeps all using Sphinx or is DOygen still a thing.

[ornate coyote]

Kicking and fighting to NOT grow 🙂

[warm pulsar]

lol. That's quite the achievement!

[simple fractal]

that reminds me. time to build that macropad.

[clear matrix]

I believe doxygen is used on all of our Arduino documentation. Sphinx on all the CP.

[eager matrix]

I started using Basecamp for side projects because you folks use it.

Ha just found an IBM presentation called Documentation in the modern age that has a slide titled "Cool kids do Sphinx" and another titled "Cool kids used to do Doxygen"

[ornate coyote]

This was supposed to be my "retirement" gig - not my "let's build and grow a new business" - I've done that before a few times in the past - didn't need to do it again. I'm failing at not needing to grow 😉

[turbid hill]

But you are having fun

[eager matrix]

But you have an audience now.

[ionic garnet]

fun and interesting are my requirements for any job!

[simple fractal]

when i retired i consulted for 10 years. then i decided that i needed more time for all the other 'hobby' projects

[turbid hill]

I really need to have another look at sublime

[pearl shoal]

Just saw you were on

[simple fractal]

sublime is really good, but now i'm vscode.

[pearl shoal]

Thanks for more work on USB Host - I will watch and catch up

[dim wigeon]

@simple fractal Most “retired” people I know are busier than they were when they were not retired.

[ionic garnet]

I use Sublime and PyCharm

[turbid hill]

I am in vscode also but I like to check out other enviroments

I did a pass at pycharm but for some reason it was not working for me

[eager matrix]

I just had to give up on Linode. All I wanted was a Ubuntu instance that I could VNC into and thier guide didn't work and their supprt folks were no help. Regrettably I have to go back to AWS because it just works.

[inner spade]

Amen to that!

I work with a company that took many Google coding processes and commercialized them into a product called Guide-Rails. Eric Billingsley is CEO formerly of Google, ebay, and Apple

[cinder wind]

What did I miss? Did Scott solve everything?

[ionic garnet]

Still evaluating

everything and more

[turbid hill]

ahh that sort of over helpfulness

[upper sandal]

every time I open a file with vscode, it opens a popup about the new update instead of just focusing my file...

granted, I don't do it every day

[simple fractal]

true, i keep finding that it cant find zephyr root or some other thing that an extension is looking for

[warm pulsar]

google engineers googlifying the world...

[dim wigeon]

You can bloat Sublime up with extensions and stuff too if you’re so inclined…I get irritated by the constant Package Control popups in Sublime Text.

[grand tusk]

VSCode aspires to be the modern Clippy.

[cinder wind]

"you know how many Tiny USBs you can fit on this big dev board?

[ionic garnet]

what a low bar it sets for itself

[sinful meadow]

yeah gotta turn off the vscode suggestions

[grand tusk]

Wouldn't be so bad if you only got them when you wanted them.

[dim wigeon]

I think TextMate started the Command Palette thing, and everyone seems to have adopted it.

[turbid hill]

yeah the original hotkey for command pallet in VSC was un intuitive

[simple fractal]

i used textmate as well, when i had a mac, then sublime, now vscode (mostly) sometimes vim

[turbid hill]

now in VSC it's just F1

[dim wigeon]

I use Sublime and VSCode and Vim and Emacs and PyCharm and mu and… 🙂

[turbid hill]

Emacs ewww

[ionic garnet]

don't forget nano!

[dim wigeon]

“Hi, I’m Tammy and I’m a tooling junkie”… 🙂

[turbid hill]

Lol

[eager matrix]

Since VSCode is open source there is a non MS verion available call VSCodium. Ive been using that for a while and it is solid and compatible.

[simple fractal]

true, whenever i ssh into something the editor is different

[ionic garnet]

even sometimes the same editor has different names

[eager matrix]

Vim and Emacs. I didn't know that was allowed.

[timid plover]

vi seems to work everywhere 🙂

[warm pulsar]

@dim wigeon what about the Arduino IDE?

[dim wigeon]

@eager matrix In college I had access to systems with both on them, and I learned to use both. Now I’m a proponent of “use whichever tools make YOU personally most productive and don’t worry about it.”

[turbid hill]

Have you tried the new v2 Arduino ide

[ionic garnet]

I tried Arduino 2 IDE. No opinion yet

[timid plover]

sorry - should I withdraw my comment ?

[dim wigeon]

@warm pulsar I usually don’t. I have PlatformIO when I need to do Arduino things. But I’m a command-line person through and through.

[ionic garnet]

Yes peace treaty

[simple fractal]

lol

[warm pulsar]

my original code editor was notepad...

[cinder wind]

emacs or gtfo all of you 😁

[turbid hill]

Lol

[ionic garnet]

haha

[eager matrix]

Sorry , I may have been misunderstood. I was poking fun at the editor ways. Of course use what you want.

[balmy tinsel]

I like the library manager in Arduino but don't use it for anything else

[dim wigeon]

@warm pulsar I heard Scott McNealy speak when he was the CEO of Sun Microsystems, and he said “let’s face it, ASCII text is a far richer medium than most of us deserve.”

[turbid hill]

You know when your old when you used the old editor on the VAX

[simple fractal]

yes platformio has been my goto mostly, but quite often i will use the mfgr ide for initial project code. to see what works.

and every semi company seems to have their own ide now

[ionic garnet]

hardcore people don't need no IDE or text editor, they enter things in machine code via dip switches on front of PDP11 (my actual first program!)

[dim wigeon]

@eager matrix For sure. I personally always thought that the editor wars were silly wastes of time, but people get so passionate about it. 🤷‍♀️

[turbid hill]

PlatformIO needs to update the ESP32 base to 4.4

[sinful meadow]

platformio is disappointing for esp and rp2040 (no support for esp arduino 2.x or the alternative rp2040 core yet)

[eager matrix]

I'm old. I learned vi before Linux was even a thing.

[simple fractal]

true. i did love to toggle in a paper tape bootloader on the front panel

[turbid hill]

Yay Kconsole

[eager matrix]

I did my first resume using troff.

[ionic garnet]

people don't realize many of us worked decades before Linux came around!

[dim wigeon]

@eager matrix I think the Linux kernel was at version 0.99.pl[something] when I learned vi.

[turbid hill]

I started linux on two floppys downloaded from sunsite via ftp by email and the kernel was 0.97c

[eager matrix]

BSD 4.1. I still have the cover to one of those manuals with the daemon on it.

[ionic garnet]

I used Solaris at Symantec for LiveUpdate backend, then FreeBSD at my startups, then Linux took over.

[dim wigeon]

@simple fractal Maybe we need a “binary toggle switch” HID device. 🙂

[simple fractal]

yes, freebsd was my first non-windows is

os

did a lot of work on those boxes

[warm pulsar]

I remember those computer eng folks during my university days lusting over slackware... ohh the good old days of 74xx logic gates. Your editor was a breadboard...

[turbid hill]

I used net-bsd on the old sun pizza box's aka 68000 processor

[simple fractal]

not including uni

we are reminiscing about 'the good old days'

[ionic garnet]

I try to not get religious about technology choices

That is exactly why Raspberry Pi was built.

[dim wigeon]

I’ve used so many different systems and platforms and tools over the years that I’ve forgotten more than I still know, I think.

Programming languages too.

[turbid hill]

I had new users at work who did not understand what Thunderbird was for

[eager matrix]

@rapid hornet Are you constitutionally able to run for president?

I started campaigning on my 35th birthday.

[grand tusk]

Hmm, raspberry pi port.

[sinful meadow]

anyone else under 30 here?

[ionic garnet]

not me. I will be 60 in September

[ornate coyote]

ha! You know you're young when you still count your age in halves!

[ornate coyote]

Not even close!

[eager matrix]

Are the younger people working on wippersnapper?

[dim wigeon]

@sinful meadow chronolgical age-wise, or emotional maturity wise? 😉

[ionic garnet]

I was thinking exact same thing!

why do we keep saying "hello world" when it never replies?

[eager matrix]

Not quite 5 if you count by 2^x.

Ooops I menat 6.

I watch folks walking by my lawn very closely.

[warm pulsar]

Wow. Lots of stuff. Ethernet?

[clear matrix]

You're not listening hard enough.

[grand tusk]

So many ETHERNET pins.

[ionic garnet]

too many years playing rock & roll guitar damaged my hearing!

[clear matrix]

Likely excuse!

[ionic garnet]

it is not untrue though!

[dim wigeon]

I feel like the boundary between “microcontroller” and “computer with GPIO lines” is becoming blurrier and blurrier.

[turbid hill]

which board do you have

evk or evkb

[eager matrix]

I have a question about the new esp32 board. Since you had to use a new USB-serial chip why didn't you use a FTDI FT2232 to get a gdb interface over USB The Espessif ESP-WROVER-KIT uses it and it's great.

[turbid hill]

hmm I have the teensy 4.0 board

[eager matrix]

I'll ask her on sunday.

[turbid hill]

cool

5v gnd tx rx

[warm pulsar]

regarding your keep host initialized on reboot: would the endpoints/pipes need to be re-initialized on reboot or would remain the state too?

[turbid hill]

used to seeing this in MB manuals and there is no consistency in USB labels

in mb manuals

Yep poor translation

[eager matrix]

Yep, The FTDI chip is about $2 more.

[turbid hill]

now that board is a candidate for pretty pins

[warm pulsar]

Thanks Scott - got to go. It's nice outside (not too cold) and want to enjoy some sun before the day is over. Have a good weekend and see you next week (?)

[covert stratus]

they usually sleep more at the start

[warm pulsar]

dm or dn? (pin names)

[covert stratus]

get lots of hugs because they're only small for so little time 🙂 and good luck!

[pearl shoal]

Ok! All caught up to you 🙂
I guess my question on pyusb is can we write a driver for the IntelliKeys that sends that EZUSB firmware at startup and then reads/writes like the driver GDSports wrote for Arduino on the M0? It seems like that would be a yes, but I don't know if there's a "driver" base class or the like

I.e. how do we add a custom device?

Right, I could just try it on a RPi using CPython

For the record, GDSports on GitHub did most of the USB Host work (I just got the original driver open sourced)

There is a great teardown by @scanlime as well

Bizarre device (it uses J/K Flipflops to read the membrane!)

Basically 1 bit memory chips

[sterile forge]

what would happen if you connected a hub?

[timid plover]

some of hwhat you are typing is covered

[inner spade]

Handy for debouncing.

[pearl shoal]

So, just to setup my weekend do you think if I get the IntelliKeys driver ported to CPython/pyusb I'll be on a useful path?

👍

[covert stratus]

thanks Scott!

[turbid hill]

thanks for the show

[dim wigeon]

Have a great weekend, everyone!

[inner spade]

Thank you!

Awesome!

[ionic garnet]

it's awesomely awesome in an awesome way

[cinder wind]

Thanks Scott!

[ionic garnet]

my job is to fund my board buying habit!!!!

see you all later. Always fun hanging out here

[rapid hornet]

Thanks all!

[pearl shoal]

@rapid hornet Just reading this - are you planning on using the existing pyusb code and just writing a backend for tinyusb? https://github.com/pyusb/pyusb/blob/master/docs/tutorial.rst

Or are you going to reimplement the API?

[rapid hornet]

my plan is to reimplement a subset of it

[pearl shoal]

Ok

And if I plan to test on a Teensy4.1 with a USB adapter, that'll be the first platform that works

[rapid hornet]

that's what I'm working on now. thach is working on rp2040 support for usb host now too

[pearl shoal]

Excellent - I will send my PCB boards out w/RP2040 + USB A Female jacks so they're ready

I have two done a QT-Py #BFF and one that holds a KB2040

[rapid hornet]

I think the pin constraint is that the two pins need to be consecutive

[pearl shoal]

Right

standard PIO

[rapid hornet]

right, so it can set both at once

[pearl shoal]

right

Will be super cool to have that ability on the RP2040

[rapid hornet]

yup

[pearl shoal]

I'll probably swap the PCB male plug for an actual male A plug

[rapid hornet]

why not just use an A to micro B cable?

[pearl shoal]

That's already on the KB2040

So that's options there

[rapid hornet]

right, I'd just use that

[pearl shoal]

So, for costs sake, even a short USBA-C cable is 3x more than the jack... and we're doing hand soldering anyway

The idea of "just stick this dongle between your normal USB printer cable and your computer" is really nice

We've tried the "use an OTG cable" and that was less than great

[rapid hornet]

as long as it fits

[pearl shoal]

Yes

[rapid hornet]

I totally get having usb a for host

[pearl shoal]

If it doesn't you stick the micro B cable into the hole

[rapid hornet]

fair

[pearl shoal]

I'll make both

Shipping is the cost - making two is no problem

[rapid hornet]

you can always omit the plug

[pearl shoal]

Yeah, but there will be spacing issues since we're direct soldering the KB2040

[rapid hornet]

ah

[pearl shoal]

All good - these are problems I like

Kinda nifty - this sends an EZUSB firmware via pyusb https://github.com/John-K/CypressFX/blob/master/CypressFX/__init__.py

[rapid hornet]

nice!

even better!

[pearl shoal]

Ok, thanks for your help on this

[rapid hornet]

np

[turbid hill]

Is this not the chip used by the signal acquisition boards CY7C680xx

[sudden slate]

Nice DD Scott 🙂

[pearl shoal]

@rapid hornet I'm finishing this design, I know the pins need to be adjacent, but does D+/D- need to be in any order? I have D- going to A0 (GPIO29) and D+ going to A1 (GPIO28) on the QT Py. and D- going to D0 (GPIO0) and D+ going to D1 (GPIO1) on the KB2040.

Perhaps that's a quetion for @hollow dust

[rapid hornet]

there is an order to the existing code but it should be modifiable

[pearl shoal]

At runtime? Or CP build-time?

like createUSBHost(board.D0, board.D1)? The way PIO works, it seems having an order might be helpful. Like D+ is one higher than D-...

Or vice versa

That way in the PIO, D- would always be "PIN0" and D+ would always be "PIN1" and you'd just pass in what the starting pin was.

[rapid hornet]

I want to say D+ is the lower of the two

you could check the PIO repo

[pearl shoal]

The TinyUSB repo?

Or the Raspi examples?

[rapid hornet]

https://github.com/sekigon-gonnoc/Pico-PIO-USB/

[pearl shoal]

https://github.com/sekigon-gonnoc/Pico-PIO-USB/blob/a09cf8917ec66cb45910a0e87a7851d80c55b0cf/pio_usb_configuration.h#L17

DP is lower

and you think @hollow dust will match that?

[rapid hornet]

ya, that's what he's basing it all on

[pearl shoal]

Great... Thanks

[inner spade]

Good morning!

[grand tusk]

Hello!

Will you be adding a cat-cam?

Chat-spam is back.

[inner spade]

A camera on a cat collar, perhaps?

[dim wigeon]

Good morning, everyone!

[pearl shoal]

Good morning, @smoky island

1/2 paying attention while cleaning

I was curious so I looked up str vs repr
repr() is supposed to be unambiguous... str() is supposed to be readable

So, str(3) and str("3") both give -> 3
But repr() should give different answers (I dunno, maybe "3" vs 3)?

str(3)
'3'

str("3")
'3'
repr("3")
"'3'"
repr(3)
'3'

[grand tusk]

I think the repl calls repr .

[wide hawk]

if __str__ is not defined it calls __repr__ by default iirc

[pearl shoal]

This is everything I know on the subject https://stackoverflow.com/questions/1436703/what-is-the-difference-between-str-and-repr

Also, there's this weird comment " Container’s str uses contained objects’ repr"

Look at the repr() and str() and see what the fourth # is

Maybe when you give them 4 values, it thinks you have an RGBW?

I would doubt it

[inner spade]

Is there a strip brightness calculation performed separately from an individual dot’s default brightness of 1.0?

[grand tusk]

Try (0,0,0,1)?

...to see if it is RGBW.

[pearl shoal]

I think the P is just the packing bits

You're putting a 24 bit number in a 32 bit type

So the P says where the spare byte is

[inner spade]

Artist.Album.Song is helpful for larger collections

[pearl shoal]

Ok, here's your Dotstar issue... you don't have to stop & read this - just for posterity.

NeoPixels and Dotstars share the underlying Pixelbuf base class. However, Dotstars can have per-pixel brightness where neopixels cannot. So when you pass (0,255,0,.5) to a dotstar the fourth parameter is used for the brightness of THAT PIXEL. However, setBrightness() on the Dotstar object sets the default brightness for the strand. Your confusion came about because your strand has only one pixel.

Here's the comment that explained it https://github.com/adafruit/circuitpython/blob/bfd56d4380c03bfc95b55dfc9f3b013fb54153ea/shared-module/adafruit_pixelbuf/PixelBuf.c#L157

More clearity here https://github.com/adafruit/circuitpython/blob/bfd56d4380c03bfc95b55dfc9f3b013fb54153ea/shared-module/adafruit_pixelbuf/PixelBuf.c#L200

Agreed - I hate it when I don't understand how things work

Nice thing about live streams is you can send folks off on errands when they don't want to clean

[inner spade]

Excellent @pearl shoal. Could be handy for fancy lighted keyboards.

[pearl shoal]

Yes, you wouldn't have to scale all the components (which doesn't really work the way you want)

[inner spade]

Indeed. Eliminates that per pixel math.

[pearl shoal]

It should be the equivalent of RGB->HSV->(scale V) ->RGB... should be handy

Gotta drop off - good luck on the winamp

I'd check for None

[inner spade]

Just try “files” in “playlist”; will error if no “playlist”

[wide hawk]

os.path.join would be useful too !

[grand tusk]

import os
def isdir(filename):
    return bool(os.stat(filename)[0] & 0x4000)

[wide hawk]

Could be neat if the base search dir would be an input to the winamp app

yah like a class attribute we could set on init defaulting to '/sd'

hahaha yah I agree that totally makes sense

[inner spade]

Future nice-to-have

[wide hawk]

Sounds good I'll look into it, I should receive my pyportal next week 😄

[grand tusk]

The output is valid python but not valid json.

[wide hawk]

Is there json.dumps in circutpython ?

[grand tusk]

yeah

I would like to see a 'trail rating' for various tasks. Adding a new shape to displayio might be a 0, implementing HDMI audio on broadcom would be a 10?

😄

[inner spade]

For me it would be nice to know how tall I’ll need to be to go on a particular PR ride.

Are there any micro/circuit Python tools for walking data hierarchies?

Thinking about database structures too

Micro SQL?

[upper sandal]

I wrote myself a directories crawler using listdir and the same as the isdir above

yes

there might be micropython implementations for sqlite

[inner spade]

Dumb = not as self-aware or autonomous

we use restream.io for all our streaming they have posted some resources and more (they are based out of austin, tx & kyiv, ukraine - https://restream.io/blog/stand-with-ukraine/

[ionic garnet]

FYI: the company I work has about 100+ people based in Ukraine. I have been in touch with about 30 now and all are OK. Thinking of them. I visit the city of Kharkiv fairly often. Beautiful city. Here's a little pic I took in 2014 of the "Freedom Statue" in Kharkiv.

thank you for standing up for peace

I have been working on visual representation of audio quite a bit

neat

[dim wigeon]

Atari was really ahead of their time in so many ways, I think.

[ionic garnet]

and they managed to inspire many of us to get really interested in the technology

[dim wigeon]

Yup. That gizmo reminds me a little bit of the Scanimate.

http://scanimate.com/

[ionic garnet]

been toying with FFT and vumeter and other ways of streaming values into an algorithm to drive visualizations lately on m4 boards

did similar things with Commodore 64 in the early 1980s

[dim wigeon]

Neat!

[ionic garnet]

I have been trying to find the algorithms, formulas, and input sources that drive the most joyful video effects. It's a fun quest

[dim wigeon]

That does sound like fun!

[ionic garnet]

I try to find cool things to experiment with all the time. It helps me wake up every day excited to do my work and pursue my hobbies.

CircuitPython makes it really easy to quickly iterate over maker experiments. Love it.

I've got boxes of old hardware junk with dinosaur connectors and peripherals. I used to worry I was a hoarder but then discovered I am just a maker

[dim wigeon]

I like that…justification.

[ashen dove]

I was wondering if adafruit was going to make a fpc breakout board for your eyespy displays?

[dim wigeon]

Though I also have to admit I learned from my grandfather, who died in 2012 with the timer from the dishwasher he had in 1963 still in a closet “because you never know when one of those might come in handy”… 🤷🏻‍♀️

[ionic garnet]

My dad was an engineer who designed jet engines his whole career, and my mom an artsy/activist. I got the best of both worlds from them

Good night Limor and PT. @open girder

[ashen dove]

thanks, I'm 25% Ukranian.

[dim wigeon]

Good night, Adafruit folks!

[ionic garnet]

that's beautiful to see people coming out to support the people of Ukraine.

[dim wigeon]

I think that Putin badly miscalculated, and I can’t decide if I hope that he lives to regret it or if I hope he’s assassinated for his trouble.

[ionic garnet]

Another picture from my first trip to Kharkiv in 2014. I was there to do a security and safety audit before engaging Ukrainian team in developing portions of Jibo ecosystem

[dim wigeon]

They do have some pretty spectacular architecture in that part of the world.

[ionic garnet]

I find the architecture in that part of the world beautiful and different

It's hard to describe how the events of the last few days have hit me. For one, I'm a C-level exec of a company with operations in Ukraine so I have a personal connection to a hundred plus people. But also I have a deep love of this part of the world and its people. They are creative, fierce, stubborn, tenacious, and resilient. They are among the finest software developers in the world.

Thanks for letting me share. On the Jibo Alum slack channel there has been questions and concerns pouring in from many Jibo-people. Now I am CTO of the outsourcing company we used at Jibo to do the server side development called Waverley Software. Small world.

[clever summit]

Hello @smoky island . What are we doing today?

Nice to see a MagTag project. Played with mine during the weekend.

[clever summit]

Time to make it pretty! 🙂

THIS is pretty!
https://blog.adafruit.com/2020/12/04/displaying-temperature-and-humidity-with-an-adafruit-magtag-eink-display-circuitpython-magtag-adafuit-jonnybergdahl/

🙂

Yep, it's mine. Got one off the first production run.

So CP wasn't even fully supporting it... Had "some" issues that tannewt helped me with.

I had fun playing with the grays!

White, Black and 2 grays it is.

If I recall I think 0x444444 and 0xBBBBBB is the color valaues you need for the gray

Ther was some bug that Arduino and CP didn't use the same colors.

Checked my code, that is what I used.

Kinda lazy just slapping a pipe char between the values? 🙂

Makes sense

Design is a DEEP rabbit hole. My UI's usually suck. Kinda proud of that Magtag project though. 🙂

[inner spade]

I’ve used ‘name’ and ‘value’ for variable names to avoid the ‘label’ vrs Lable conundrum.

[clever summit]

Might be time redoing it with all the new graphic stuff you have been doing since I made that.

I use "caption" instead of "name"

[inner spade]

Striving to develop UIs that look familiar to the eye and hand/gesture

[clever summit]

I would typically right align the values

Oh, you can't align a text block?

You are not just trying to get me to fix it? 🙂

[inner spade]

Can a formatted string be used in Label text?

Ah yes, variable spacing

[clever summit]

Do you have space to change c to C? C is the official shorthand for Celsius.

[inner spade]

Alignment based on a character like “.”

[clever summit]

Looks on the limit

Kelvin = K

[inner spade]

“K” is correct

[clever summit]

Ah, the tedious parts of designing. Lol.

The power of CP, just imagine doing this in Arduino.

Yeah, I did some iPhone apps couple of years back. Tedious.

This was pre Swift, so Objective-C.

[inner spade]

From a learning guide audience point of view, the new version contains the same programming techniques and rich design. Keeping the old stuff might be confusing.

Thanks for the stream!

[clever summit]

[ionic garnet]

bought mine already. Last week I missed out for snoozin' for 3 minutes

[digital crescent]

the blue one looks really cool

made a clock

[cinder wind]

nice!

[ionic garnet]

I bought one in each color

[dry marten]

They are already out of stock

[fringe niche]

Had one of each in my cart. Disappeared before I could order.

[ionic garnet]

that happened to me last week

I wasn't too greedy. I got one of each.

[viral sail]

I couldn't find the option that had JP's face making up the digits though.

[upbeat coral]

I ordered two but when I got to my cart, it says out of stock.

Well, that bites.

[ionic garnet]

My new algorithm is to go to the product link while music plays and order immediately. Worked today

[cinder wind]

I believe the individual components of that kit are this backpack: https://www.adafruit.com/product/877 and then one of these displays https://www.adafruit.com/product/813

Thanks all, sorry about the quick sell through for people who didn't get em

[green bison]

I've been thinking this would be a great product for a while! Glad to see adafruit did it!

[dry marten]

No worries @haughty quiver
I tried but I was not fast enough

[upbeat coral]

I just think it bites that items in your cart can be in stock when you start to check out but be gone by the time you get logged in. First time I've had a shopping cart do that to me.

That only shows how to either do a keyboard or emulate a mouse by using a joystick? In order to make a trackball, wouldn't you need something to read the movement of the ball? using a joystick would be very impractical.

[viral sail]

Thanks @rocky reef & @hard hollow . See you all tonight.

[ivory kiln]

[lavish patrol]

Another great show guys. 👍

[ivory kiln]

indeed, great show guys. 🙂 Espetially liked the etch i sketch. 😄

SHOW and TELL 3/2/2022 LIVE! https://youtu.be/LiuH1YcBpDk

[smoky island]

Good evening everyone 👋

[dim wigeon]

@turbid hill My day was looooong. But productive so there’s that.

[alpine radish]

mine my oreoductive -- I ate oreos.

[turbid hill]

I had a broken raid and spent the day fighting fires

[dim wigeon]

Auto correct did not in fact correct anything there. 🤷‍♀️

[alpine radish]

I made this:

Easier to tell from the less populated pic. Shows the variation of gravity (from mean) over the surface of the earth.

[turbid hill]

lol looks like protein spikes on covid virus

[dim wigeon]

That’s cool!

[smoky island]

Pretty graphs!

[alpine radish]

Thanks!

Glad it worked out 🙂

[turbid hill]

are you saying the at the equator I weigh more....

[alpine radish]

Actually marginally less.

[ionic garnet]

cyber attack risks are very real!

[alpine radish]

Sorry -- red is below average, purple is above average.

[turbid hill]

oh so the poles

[alpine radish]

I used the rainbow as the scale -- with red the minimum acceleration, purple more.

You weigh marginally more at the poles.

[dim wigeon]

That color scale goes in the opposite direction of what I’d expect, but maybe that’s just me.

[alpine radish]

Ooh -- that's important feedback.

What would you expect?

[dim wigeon]

I’m accustomed to “red = higher value, blue = lower value”

[alpine radish]

(It's a super easy fix to swap 'em)

[turbid hill]

considering the globe is bigger below the equator

[nova totem]

And the best part of a CRT you can still play Duck Hunt

[neon pelican]

[waxen thistle]

Good evening all you most excellent people!

[alpine radish]

guess scott's password based on the heatmap....!

[waxen thistle]

[nova totem]

That actually just gave me an idea to try colorwheel on

[turbid hill]

lol spaceballs

lord helmet, they gave us the raspberry

[waxen thistle]

hmm. jam.

read this article https://www.bigmessowires.com/2021/11/12/the-amazing-disk-ii-controller-card/

[rapid hornet]

that's the beauty of working on open source

[turbid hill]

@robust horizon read this about how they find sectors https://www.bigmessowires.com/2021/11/12/the-amazing-disk-ii-controller-card/

[robust horizon]

@turbid hill yup! That is one I've read. Any more links, absolutely feel free to send them

[smoky island]

Batman trying to sneak up behind you!

[tulip canyon]

Currently reading that.

[turbid hill]

@robust horizon That was so fun reading and so amazing how Woz made the software do all the work and they got it all running in 3 weeks

[alpine radish]

@dim wigeon My gift to you:

[waxen thistle]

And it's from the MIT press!

[dim wigeon]

Nice! And yeah, that matches what I expect color-wise. (I’m a data engineer, so…)

[alpine radish]

Awesome job on this turn timer! I love the interface you've created with the segments and buttons. @nova totem

[waxen thistle]

Rotary encoders have me spinning in circles.

[daring elbow]

Hey. y'all.

[nova totem]

Not yet but that is a great idea. I need a power switch or maybe a way to single game over

[nova totem]

Thanks, it turned out way better then I thought when I first thought of it

[digital crescent]

total time and avg time taken

[daring elbow]

If I can get here on time next week would y'all be interested in a Tiny Memex show and tell? https://twitter.com/TransmutableCo/status/1498396885513474049

Trevor Flowers at Transmutable Goods (@TransmutableCo)

It's a nice coincidence that I completed the first Tiny Memex on the Raspberry Pi's 10th birthday. Inside is a Raspberry Pi 4 with a custom adapter hat to drive the displays and to receive input from the lever and the many buttons. #RaspberryPi10 https://t.co/XCzjtZ002m

@low fractal nice find, I just ordered the book and it will be here tomorrow. I'm also old enough when at lot of this stuff was brand new and was being created.

[cinder wind]

yay first episode of CirPyShow is great! @clear matrix is awesome

[split gazelle]

first episode with @clear matrix was great @open surge

[robust horizon]

I haven't listened to it yet! It's on the short list though.

[nova totem]

@open surge Can't wait to listen later this week. It'll be the first podcast I've listened to

[ionic garnet]

I need to listen

[clear matrix]

@cinder wind @split gazelle Thank you!! 😊

Thanks @haughty quiver !

That's a crazy cool popup book

[cinder wind]

Thanks pt thanks Limor!

[waxen thistle]

Thanks everyone for sharing your awesome stuff! And thanks @low fractal for yet another book I need to check out 📚

[dim wigeon]

@open surge I just added the CircuitPython Show to my podcast feeds. It took me a minute to find the right RSS link, though…I wonder if there’s some metadata you could add to the home page so you could point a podcatcher app at the home page and have it discover the feed URL automatically.

I know that works on other podcasts I follow, but I don’t know how hard it is to make it work.

Hmm. Jam packed. 🍞

Very happy to kick this to the curb.

Glad to have Covid mostly behind us. Sadly, 70% of my company is in Ukraine

or ask me. I'm a c-level exec of tech company with big pressence in UA

we started offering evac in Jan

[dim wigeon]

@turbid hill So if you butter both sides of the toast, will it levitate above the floor spinning in a circle? 🙂

[ionic garnet]

but UA residents are stubborn and want to stay and fight

[turbid hill]

@dim wigeon Lol

Do they still sell the ammo for those Polaroid cameras?

[turbid hill]

I thought some company got the gear from them to make the film

[dim wigeon]

I think some folks bought the film technology from Polaroid and are making film again, but I’m not sure for which cameras.

[ashen hound]

earlier today, you showed off a linux feather board in the works. Is it going to be a two-layer board?

[last bane]

Is there a good resource to use to figure out the name of various connectors from pictures? I'd like to buy various pigtails for the landscape power supplies used in holiday inflatable decorations and it's difficult to find a matching connector when the power supply fails. 🙂

[median relic]

I just put my Adafruit order in for my dog's new collar! Is it possible (and affordable) to have a custom flexible surface mount pcb made? It would go inside Cory’s collar with the micro, GPS and LoRa modules spread out for thinness! It would be neat to surface mount the parts rather than hand wire them.

[echo canopy]

Question @open girder

You showed the ESP doing video out .. while a simple connection… any plans on a breakout ? Something like a backpack? Featherwing? Or could the pin be manipulated to go out a qwiic connector to a breakout ?

[short chasm]

@open girder QUESTION: Is it relatively easy to upload a bootloader to a RP2040 chip? I want to design a board from scratch and I've previously loaded bootloaders on a few different AVR chips.

[inner spade]

Q: Will a touchscreen version of the new 1.9" TFT display become available? Are touchscreens of that size feasible and useful?

[dim knot]

Q: I wonder what kind of flexible connectors are used in thing like older "slider" and flip phones

[short chasm]

😱 mind blown. thank you lady ada and phil!

[midnight plinth]

QUESTION : will the Feather be denoted in the catalog pages? meaning the esp 32 varients

[glossy basalt]

What’s your preferred connector for single wires in small gauge wires? Bullet, spade… along those lines?

[median relic]

awesome, thank you!

[vivid ore]

Question: I've been experimenting with the 40-pin RGB TFT friend and some microcontrollers. Do you know of any experiments done with driving such a display with an RP2040 or ESP32?

[upbeat coral]

Thank you for taking time for us.

Thanks for the feedback, that's good to know, I'll work on that.

@dim wigeon Thanks for the feedback, I added a big RSS button on the front page: https://circuitpythonshow.com/

[robust horizon]

I had to duck out in the middle, will catch it on replay 🙂

[light stump]

As ladyada mentioned, the ESP32-S3 can drive RGB LCDs. Related: Here’s an issue tracking what it will take to add RGB LCD “dot-clock” driving displays capability to CircuitPython. https://github.com/adafruit/circuitpython/issues/6049 Also there is example code in the ESP IDF.

[inner spade]

Is there an equivalent CircuitPython IR library?

[smoky island]

Yep, I am joining Scott this week (tomorrow) to chat with him during deep dive.

[smoky island]

There is. I'm not sure of the name, Will take a look and link it if I can find.

[clear matrix]

IR_Remote ? Or am I not even close to what you folks are talking about...

[smoky island]

Ah, yep I think that is right. Or at least that is the same one I am thinking of.

there sorta is, but it's not nearly as advanced: https://learn.adafruit.com/ir-sensor/circuitpython
