Dollar for dollar, RISC-V cores are unlikely to match ARM yet, in the general computing space, due to a few reasons that come to my mind:

1. Economy of scale on the hardware side. Performant chips aren't yet manufactured in a high enough volume to compete in price.

2. The ISA and therefore chip designs are about 10-15 years younger than ARM. There are a lot of extensions that need work still and designers need to learn to optimize more.

3. Firmware/software support. Since it's a young ISA, there's a large amount of work still to be done to get ARM performance across the board. The open nature of the ISA is likely accelerating this, however, as low-level devs have much more access to the ISA spec to develop their APIs against.

[inner spade]

Good afternoon! You too, Lars.

(Trying to appease him.)

[lavish patrol]

Hello, good people.

Lars shall not be appeased... 😉

[spiral vale]

its time!

[split gazelle]

Good afternoon folks

[lavish patrol]

Hi, Liz. 👋

I've had a great day. Last night a filling fell out, so I've been walking around all daywith a hole in my tooth. Fun times.

[haughty quiver]

🦷

[viral sail]

Good afternoon.

[inner spade]

It’s like having a guitar pedal for your whistle.

[spiral vale]

oh hai... i didnt see you there

[lavish patrol]

Junevember. Not to be confused with Octuary, or Decril.

[cinder wind]

yeah, why so gray in California? it's so grey. and gray.

[haughty quiver]

muy gray

[lavish patrol]

It's gray on Wednesbury...

[cinder wind]

The view out my window right now. And for the last 6 months it seems

[lavish patrol]

I think the UK has got SoCal's weather...

[cinder wind]

heh

[lavish patrol]

Ok, 30C (86F) isn't hot, but hot for the UK.

[cinder wind]

wow yeah! esp since no one in the UK has A/C

[inner spade]

A Python diode.

[lavish patrol]

A Pyode?

[cinder wind]

if it runs on a Raspberry Pi Pico in CircuitPython , is it PiPyPicoPyode

[spiral vale]

PiPyPiPyPs2PicoPico

[cinder wind]

The ps2controller library I made is pretty much just a Pythonization of one of the (many) Arduino libraries: https://github.com/todbot/CircuitPython_PS2Controller/

kinda weird seeing a nodal flow graph for a CAD model but that's really cool

[clever summit]

Evening mr. Callaway

[split gazelle]

And I thought fusion was hard to follow 😅

[lavish patrol]

Lol

[clever summit]

Check out OpenSCAD then.

[cinder wind]

most of what I've seen of Grasshopper in Rhino was that it was all Javascript-based

[clever summit]

You write a program that creates the shapes in OpenSCAD.

[spiral vale]

Rhino = $995

[cinder wind]

so about the same as Fusion360 and not nearly as irritating business model

[lavish patrol]

Big Clive likes OpenSCAD.

[cinder wind]

wow Rhino gives you a 90-day free trial, and then just saving is disabled

[spiral vale]

posted an inkline above

👏

[split gazelle]

I also use the chopping model method for testing

You can do that

But it’s annoying if I recall depending on the chonk

[digital geyser]

Hello everyone!

gonna try Rhino, for the summer 😉

[cinder wind]

Yes, in PrusaSlicer at least you can insert "negative volumes". and then move them around to cut geometry

Good evening deep divers 🤿

[sand lotus]

did you ever figure out the thing you were working on with the esp32spi (airlift coprocessor)?

think it was to make it more like requests. the portalbase stuff is a maze.

nvm i think that's an ongoing thing after listening to in the weeds.

i have family visiting and exhausted them working on house stuff, they're taking a nap now tired lol. so i have free time to enjoy your stream. not sure if i'll be around for tomorrow. enjoying at least part of the regular routine for now.

color+160000 i've never seen that, neat. makes me think i've been using color wheel wrong.

i made some code to translate it to 0-255 in separate RGB values though with pwm

i think it was 169 vs 170 issue, i remember this one yeah

geez you had to go deeep to figure that one out

ohh i thought when you said colorwheel you were using the rainbowio colorwheel

that's even smaller and seems more efficient, nice

[left pier]

👋

[brazen grove]

guete abig

(it's "good evening" in Swiss)

[sand lotus]

seems like anytime i make a change i have to rerun black. i thought black was supposed to do that stuff automatically if it had previously been run on a file or directory?

maybe that doesn't work in that way with windows git desktop...

[left pier]

/* Depending your IDE */
You could have it format on every save.

[sand lotus]

ahh it's pre-commit not black, nvm. thank you.

sometimes i'll click on the commit details on the git website just to watch it scroll through the thousands of things it does. kind of mesmerizing.

Change to vertical button orientation to get four buttons in a row

[sand lotus]

good morning ☕

[inner spade]

Or just use it in portrait

[sand lotus]

family is here and rearranged my entire kitchen. they put my coffee maker in the dining room i was quite upset. have you ever visited someone's house and just randomly started rearranging the furniture in their house? didn't know where all the pieces to make a cup of coffee...

[inner spade]

Rent a tent and send them to the back yard.

[sand lotus]

they're family.

[inner spade]

Interesting that the white board sketch is vertically oriented like the buttons would be if left in portrait

[inner spade]

Okay. Substitute RV for tent and driveway for back yard.

Would be nice to match button orientation with display contents

Liking the state dictionary concept. I’ve used a State class object, as well.

State.current from the class was useful

[sand lotus]

in this case i'm in favor of getting rid of the blinka icon too. need more space.

[inner spade]

Included a couple of finite state machine helpers in the class like set, advance, etc.

That ultimately were just overkill

[sand lotus]

You can use the free Cryptool to kind of see the inner workings of enigma. There are many different revisions of the machine it's not just one machine.

https://www.youtube.com/watch?v=FG59my_HLtI

I used cryptool to learn a lot about basic cryptography. Can highly recommend.

The youtube channel and lessons are excellent.

It's an interactive channel too, they have cryptography challenges that bring back old crytopgragy messages from like the 1500's to challenge you to crack using the tool. It's run by an an ex-German crypto guy, equivalent to German NSA. He's an authority on cryptography. Cryptool can crack basic substitution and even monophonic ciphers in like 30 seconds. It's not just a toy but a real tool. Advanced lessons allow you to create an encrypted video stream like skype but really private. If you want to learn anything about cryptography Niels is "the guy".

I got into it because I was participating in trying to crack the Zodiac Killer code for while. It was a worthwhile pursuit, learned a lot about cryptography in the process.

[wind spoke]

Hi. Not sure the story of the hack is unique...

I had a presentation of the work from Polish scientist, that was parallel to maybe the UK story you know.

About Enigma crack.

The thing about Poland participation is that for a long time they were on the "wrong" side of the wall, so that story was not propagated.

[sand lotus]

There are still plenty of ciphers century's old that have never been cracked.

cryptool is a program yes.

[wind spoke]

The break through I know of was related to capturing a machine and the code in a submarine... that was before being expose to whatever Poland was doing.

[tiny grove]

Poland reverse-engineered the enigma discs at the time, and they worked on it years before Britain due to the fear of German invasion. Bletchley Park and Turing built on that knowledge.

[sand lotus]

oh it'll do md5, aes, etc..

yup, poland and the bomba's which directly lead into bletchly park's hands.

[wind spoke]

Start with ROT13... or variable ROTx. 🙂

[sand lotus]

the history of alan turning's machine actually began with Poland's work.

poland definitely didn't get enough credit in the 'imitation game' movie for their work

[tiny grove]

Indeed

[wind spoke]

ROT13 is shifting 13 in the alphabetic order. ROTx is where you choose the number, and that is your secret. 🙂

[tiny grove]

... except that it's not a secret because as soon as you look at letter distribution the offset can be easily calculated.

[sand lotus]

yes rot is easy, some of the earlier ciphers were rot or letters printed on a strip of leather and wrapped around a scroll.

which then became rotating wheels, hence the rot.

his youtube channel covers a lot of history about encryption and is really neat.

[wind spoke]

Did you try to have the MacroPad keyboard be a "window" on the full keyboard... and using the rotary to move the windows left and right. So the initial display could show:

123
QWE
ASD
ZXC

So you have a full keyboard, just rotate and press a key.
Then if you configure crypto first, you can have a keyboard that does not "usb-hid print" what you see, because it print the encryption result.

You want to send the encrypted to the computer... but keep the secret in the MacroPad. At least that is the encryption side.

Not to the computer, to your friend.

So decryption you want to display only... so typing what your friend send you and see the message.

For encryption, you type and your Macropad change it.

[inner spade]

I’m a big fan of defining as many static display objects up-front as possible and revealing them when needed

Have even resorted to combining and placing them in a single background bitmap then covering each with a solid polygon filled with the background color.

[sand lotus]

doing that kind of thing on a black background is easy. if you have an image background you have to remove the group label or pop instead. haven't seen a lot of uses with pop lately but i really like the idea of pop.

in bigger scripts where ram becomes a concern wouldn't something like remove/pop be more prefrable?

[inner spade]

… or a known background color

[sand lotus]

right but my background is an image wallpaper on my feather weather as an example

right but that's lcars

take a picture of a landscape image as a background for example

[inner spade]

Yeah, solid background colors are easy

[sand lotus]

not so easy with something like that

ah depends if it'll come back or not for pop vs hide group. that makes sense. thank you.

[inner spade]

object.fill or object.color = None is also an option.

[sand lotus]

ah could do that too. never thought of that, thank you.

hmm they're labels though, can you set a text.label to none? i usually just hide them now.

[inner spade]

Would be text.color = None

[sand lotus]

didn't know text color could be none 🤦‍♂️

that helps a lot, thank you.

[inner spade]

Sorry, label.color=None

[sand lotus]

ahhh

can experiment with it, thank you.

[inner spade]

Or label.text=“ “

[sand lotus]

welcome to my ted talk about triple quote strings 🤣

i do that in headers because i have no idea if SPDX will continue if i keep using code comment in the header so i triple quote stuff to break out of it. meant to ask about that.

i'm using displaytext as label not using bitmap label

and ondiskbitmap for the bg image

An official McDonalds tetris McNugget. Something I don’t think anyone would say in their lifetime.

[open girder]

thank ya!

[autumn turret]

Would there be a way to identify the chip through the test points?

[ashen dove]

Might be able to use a scanning laser to burn through.

[open girder]

@autumn turret likely not possible - its going to be a very simple OTP-flash 8051 or alike. something very very cheap and low power!

[autumn turret]

Oh well, worth a shot! Thanks 🙂

[verbal river]

Did they have to use a 1980's passive LCD screen too?

Hello!

[sand lotus]

blog post for JP's PPOTW is going to the neopixel driver https://blog.adafruit.com/2023/06/20/551861/

product 5766? doesn't seem right with the stream title about ANO

[haughty quiver]

This is what we call a mis-direct! typeo 😦

[viral sail]

Good afternoon.

[sand lotus]

lol

[inner spade]

That’s okay. I’ll buy whatever I’m told to buy.

[haughty quiver]

fixed!

[sand lotus]

https://tenor.com/view/star-trek-star-trek-first-contact-borg-borg-collective-adapt-gif-23240427

must have been a shield frequency typo, fixed. 😛

The ANO wheel is not discounted but that's ok. Picked some up.

[undone onyx]

Time to make myself a MyPod 🙂

[sand lotus]

Liz's synth guide with the multiple ANO encoders is amazing.

[cinder wind]

scroll down? but I don't have the encoder yet!

[undone onyx]

Looks like a Jogwheel! east exercise here I come

easy (short fingrt typo)

[rotund marsh]

Can use the rotary with Adafruit MacroPad using it's Stemma QT connector?

[cinder wind]

yes, I believe so. this board is stemmaQT, so plugs right into the MacroPad's StemmaQT port

oh yeah what JP sez

[slow spire]

To the plastic tops pop off?

[rotund marsh]

Neat! Look forward to trying that out

[cinder wind]

and you could wire up multiple of these encoders

[viral sail]

Thanks @haughty quiver

[frozen orbit]

i was gonna get more, but ran out of encoders

[rotund marsh]

Thank you @haughty quiver / Adafruit team!

[inner spade]

Thanks!

[cinder wind]

Thanks JP! I'm always amazed at how well you can get through the "saved to video" portions of your livestream. I'd have to be doing about 5 retakes ahaha

[haughty quiver]

[frozen orbit]

Thanks JP!

Not like he wasn't personally visited by Prusa during their new MK4 release with a 1 hour video, him in particular is a little more biased than others. Take his specific opinion with a grain of salt.

There are no protections, if you don't prosecute, which is what they are not doing. They want to just not deal with theft.

@open girder Here's an alternative for an even lower-profile screwdriver. ANEX is the manufacturer that's used by Snap-On for their copy of these.

Is it easy to solder to the aluminium backplane?

[open girder]

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

[slow spire]

@open girder

[sand lotus]

good question. depends if it's just silkscreen or also soldermask if you can scratch it off to solder to the board.

would make for a huge ground plane

[wild urchin]

I would think you would need pretty aggressive flux to get through the oxide layer on the aluminum? But I'm not good at soldering.

[haughty quiver]

those are so cool!

There are many knockoffs/alternatives on Amazon - search for "low profile screwdriver".

Hi, I watched John Park Workshop yesterday, I found the synth with the pico was awesome. Does the code is share somewhere ? Thanks

[unreal bay]

Think he might have said it would be added to video description, or released as part of a learn guide, but also he's going to be away for a week so look at the new learn guides in a fortnight:

@cinder wind says he'll be adding video to that page soon, too

[sand lotus]

@haughty quiver This is a question that comes up about once a month. Is the code in Parsec's available somewhere? If not please consider making a parsec repo especially since lately the streams have been in 720p and trying to copy code from a 720p video is... full of squinting. 😉

Good evening deep divers 🤿

[austere pollen]

👋

[sand lotus]

PicoDVI and DisplayIO stuff today ❤️

[cinder wind]

yes DVI in CircuitPython... so good

[sand lotus]

after the DVI there's very little ram left for big projects, it's good for demos and basic use. hopefully they'll improve it with a huge buffer somehow in the future.

[cinder wind]

if you can't get a DVI Feather, the Pimoroni "Pico DV Demo Base" is also very good

[sand lotus]

using it with OBS as an overlay opens up a ton of possibilities though

[austere pollen]

Honestly the entire thing seems kinda cursed. Python on a MCU. DVI on a MCU (without dedicated hardware). 😆 Amazing that both of these things work

[sand lotus]

ah that's a smart way to resize without aliasing pixelation, smart.

[sand lotus]

IKR it's kind of amazing someone figured out how to do it in the first place.

test

[austere pollen]

test

[sand lotus]

it's updating ok again 👍

not using root group yet?

eh it's like f-strings, takes a bit to change habits

same, i'm getting used to them and actually much prefer them.

started porting api's to settings.toml, will be another change to use that instead of secrets.py all the time.

[unreal bay]

I quite like os.getenv, feels more like a PC thing declaring device specific environment variables

[inner spade]

Finally found the WiFi reliability issue(s) with the PyPortal Corrosion Monitor, so I’m commencing the shift to settings.toml and web workflow.

[unreal bay]

Web workflow makes the bringup very quick, and in-situ tweaks (risky but...)

[haughty quiver]

Code examples here:
https://github.com/jedgarpark/parsec

[cinder wind]

maybe HDMI capture dongle in YCbCr mode instead of RGB or vice versa?

[sand lotus]

Deep Dive Pride

actually with it right on the surface that's a shallow periscope. 🤦‍♂️

[cinder wind]

I just looked on mine, and I definitely had a problem with YUV vs RGB mode (for me, RGB mode was correct) (for my camera, not my DVI boards, I've not tried DVI board to HDMI capture yet)

[sand lotus]

I've used it with hdmi capture and works fine

using the one from adafruit's store anyway, only one i've tried.

i didn't check for perfect color reproduction though. could be stream compression since the black on the flag looks a little dark grey with higher gamma.

which stream compression algorithms are known to do. getting solid black during streams is pretty hard especially with youtubes compression.

however the picodvi repl black is a good solid black so dunno 🤷‍♂️

it's just a flag on the screen, would be better to show monitor capture for gimp. staring at a full screen flag kinda not really helpful to see the process.

there we go 👍

this is much better showing code & gimp.

[brazen grove]

can you really call it a flag if it's non-binary? ;-)

[sand lotus]

as long as the flag doesn't have 8 colors?

[brazen grove]

I mean, a flag in IT is usually of type bool, with only two possible values, True and False...

[sand lotus]

yes but binary is 8 digits of 0 or 1 😉

[austere pollen]

I think using multiple analog inputs to store the colours would make it at least kinda non-binary

[sand lotus]

so non-binary could be anything other than 0,1, or 8 really otherwise programmatically would be ironic. i know what you're saying deshipu.

as long as it's divisible by 240, so 1px should still work out fine

if you do a vertical sprite sheet

[clever summit]

🇸🇪 👋

[sand lotus]

well done, for loops ftw

[clear matrix]

flftw

[sand lotus]

with overlays could make tartans

[brazen grove]

no slice support in tilegrid so far

it would be really cool, especially if they were generalized to 2d

goodnight

[unreal bay]

If you haven't got an exact number of pixels dividing into screen height, could you alpha blend the gaps / transitions / extra pixels

swap gimp from PX to PC(%)

by the zoom dropdown?

yeah just referencing the shapes/band positions by percentage rather than scaling image. Apply to display height as multiplier, then display agnostic too

@smoky island might want to look into changing your custom youtube url name? You can do that in the channel settings (if you want).

[smoky island]

Thanks, I'll look into that. My YT account is all weird because I had one before it merged with google and I ended up with 2 as a result. but they are "tethered" or whatever

[sand lotus]

same, i lost one of my accounts during that whole YT to google fiasco because i didn't log into it for a while. they merged and moved stuff. it was a pain. setting up a custom channel url is relatively easy in the settings now though.

[smoky island]

☕☕

[sand lotus]

got my coffee good morning

today's project continued from yesterday's stream https://www.youtube.com/watch?v=ZxYlMu4JLKY

interesting color issue. obs issue or capture adapter?

i'll have to look into the one i have again and see if there are any color issues.

color wasn't even on my mind when doing the overlay stuff.

could just make half the flag vertical then mirror?

if the flag is anything other than stripes that wouldn't work as well

[unreal bay]

how does that set-boundary command off of shape play out? It mentions setting rows, does that mean you could visually do a non-sqaure by effectively using foreground+bg colours?

[sand lotus]

just make half a bitmap and mirror it with the axe? does displayio.shape work with bitmap?

or is it vector based?

what use case would displayio.shape be better than round rect for round rect? i mean round rect works pretty darn well.

i've only used roundrect with a solid color though... maybe it's better at using shapes with a round rect?

vu meter

ah you could do polygon style shapes where roundrect is only ever going to do roundrect.

[unreal bay]

Please. use height // flag_colours for band_height

[sand lotus]

i would consider folding and mirroring two completely different things. i've never even heard of folding other than perhaps the way you did the flip clock.

which was just a visual 2D trick but a really good one

what is display.width//2 instead of display.width/2?

[inner spade]

Made a 6E5 “Magic Eye” tube emulator with a combination of shapes and vectorio a couple of years ago. Similar to a VU meter but with a linear response.

[unreal bay]

sorry flag_colours was me, I had the flags in array, then each had colours list, so band height was dynamic. I wanted a screensaver to prevent burn-in. I gave up at triangles and axes etc. So this is informative

[sand lotus]

that looks cool, overlap is a nice look.

[unreal bay]

yeah len(pallette) was effectively what I ended up with inside the for_each flag

[inner spade]

https://youtu.be/rP3OB-wEDLM

[unreal bay]

Is it more like you're defining a boundary line for later region_filling?

oh that

[sand lotus]

maybe because you're mirroring it?

amazing how fast you can load up different versions, usually takes me about 5 minutes.

yes now the unfolding you were talking about makes complete sense.

[unreal bay]

Set mirror_y=False again, but with X true, didn't it not chop the top right corner or am I tired?

[sand lotus]

FoamyGuy and displayio bugs...

https://tenor.com/view/squirrel-gif-25096048

because displayio is so extremely useful, all of it. so if anything is wrong that is just unacceptable.

true, i've never used it. most people doing widgets would be more likely to run into it.

[unreal bay]

Looks good.
I got to get you trying wokwi, they've added CI support, it's online simulator. Can run any .bin, but also has mpy+arduino native support. Only screen though is ILI9341 + cap-sense

also vscode support

[sand lotus]

i've used it many times to run code to help people in the circuit python channel so that i don't have to grab a pi pico and use the hardware as a test.

especially for basic button and blink demo's. it works well. it can run small LCD/OLED displayio emulators too.

[unreal bay]

would be perfect for verifying expected image output from displayio. Also has logic analyser component and wifi capture i think (generates capture files).

[sand lotus]

there was some regression that happened with one of the 8.1 beta's i think? no idea what was regressed, i think it was only espidf stuff though.

[unreal bay]

y used to be settable over half_height, based on mirror_y. Now it cant be.

[sand lotus]

ah there's been work on the ISFL and RGB matrix stuff since then

but you're not using those in this case so 🤷‍♂️

might be something to ask scott or devs about. moving an * might have an impact agreed.

like t* def would be different from t *def i'd think.

[unreal bay]

like Pi being KVM+GPIO box, can be done for embedded TDD / CI

I will host it as soon as you're ready... 😉 Garage Test Farm

[sand lotus]

imagine running a github action that runs against a wowki for every build for every /example script and returns errors if something breaks.

automated tested of every example on every piece of supported hardware could have huge benefits

[unreal bay]

this is why i raise it. They are currently asking for CI users

I only hesitate because not many sensors, only basic components.

[sand lotus]

this is true, would have to emulate all modules and accessory boards too. oof. that's a massive undertaking.

[unreal bay]

I've been keeping up on the simulated components. You can add custom chips now in c too not just assembly / verilog

[sand lotus]

however right now the methodology is "release a build and if something breaks someone will report it"

[inner spade]

Could the Spice simulation data architecture be useful, perhaps?

[unreal bay]

It was fetch last (after board), but you miss-spelt submodules

[sand lotus]

https://learn.adafruit.com/building-circuitpython/recent-changes

stuff about submodules

[unreal bay]

oh, read the docs time sorry

fetch-all-submodules

[sand lotus]

yeah then you're gonna have to do fetch-all 😦

[unreal bay]

or fetch-port-submodules, which is used from port-specific Makefiles.

[sand lotus]

if it's 7.3.3 or 8.0

[unreal bay]

make remove-all-submodules removes all submodules and cleans up, so you can do a fresh make fetch-all-submodules or fetch-port-submodules. Use when you get errors fetching

got to be in root 🤦‍♂️

Nicely in the weeds. At least bugs are getting sqaushed 🐛

[sand lotus]

protomatter in pyportal makes no sense because pyportal is the built in display

[unreal bay]

does make fetch-all-submodules work in root

[sand lotus]

unless it's specifically for blinka compatibility layer?

displayio rabbithole

https://tenor.com/view/hole-rabbit-hole-alice-in-wonderland-disney-animated-gif-5928662

[unreal bay]

i2c for the win

[sand lotus]

the power requirements for almost anything running protomatter over i2c would be too high from i2c alone.

protomater is mostly for matrix panels

matrix portal has one of those 8 pin idc connectors yeah

pyportal isn't the matrixportal though

i believe it did but originally on blinka only. protomater was ported from blinka i think.

you're right it was arduino c first not blinka

it was protomatter but renamed rgbmatrix so even seeing the name protomatter still being around is weird.

[unreal bay]

delete old build folders?

git submodule update --init --recursive

or something

That newer command (2nd one) looks like it gets just the last commit needed no history (or depth 1) for each submodule

encouraging

timed out, not seen that before

[sand lotus]

long way around, sometimes it's like that

[unreal bay]

thank goodness you know displayio / bdf stuff

lol. also, update the dev channel 😉

is that tags because backported or just contained?

only tested 8.0.0-1 didn't we, not -0

@sand lotus - memory test ?

[sand lotus]

i have no idea

2022 had a lot of issues with loading glyphs but no idea about build issues

there was one issue about pystack errors with the bitmap fonts

[unreal bay]

once I've got submodule problems I usually end up recloning. One day I'll master cleaning them properly

[sand lotus]

yeah there's no build errors logged specifically for the bitmap font issue tracker

ah it would be in cp main, i was looking in the library

learned a little how to find old issues, that's a nice thing to learn

[unreal bay]

it's between alpha 1 and alpha 0, smaller bisect

[sand lotus]

oh alpha 1 was a bag full of cats, i had a lot of issues with that. things started smoothing out around beta 3

[unreal bay]

sure thats the correct device? it reloaded USB drive but hdmi didnt

rofl. not seen that one before. Actually, except when it has unsaved changes

what are the x-pirate releases?

are the releases tagged?

Does it legitametely follow the pirate dialect? Now I am a fan. Cornish Pirate here...
Everyone loves a good sea-shanty

This is where I dream of AI making my life easier. "The bug is between commit X and Y, use wokwi and test the image until the change occurs using git bisect and the pyportal board (ports/atmel-samd working folder)." - Now I go and make a cup of tea or get on with other work.

[sand lotus]

that's tony stark stuff, maybe someday.

[unreal bay]

Nah, just need to get a few things strung together, and a wallet bigger than mine. Use auto-gpt type thing to define and keep the tasks going, then chatgpt to write the script to run on wokwi, then plugins to interact with wokwi and post code there (plus execute). Then visual feedback needs another tool, either convert to svg and read the svg with chatgpt, or some visual diff tool via API that confirms image1 != image_from_bisect_commit_2

It's python plus ai/ML plugins

visual testing exists for web easily, wokwi closes the embedded gap

[sand lotus]

8/18 to 10/1 so you can have an easy chat place to refer to

[unreal bay]

1 is correct for y, as 0 is self, but rest should increase, whats old code?

[sand lotus]

looks like a simple copy paste error where someone forgot to change the index numbers

[unreal bay]

bug fixing / rabbit hole aficionados

[sand lotus]

oh just wait for Hacktoberfest, it's pandemonium for bug hunts.

[unreal bay]

Perfect for the keyboard input REPL work going on at the moment

[sand lotus]

that's a cool feature, i like that

could we use that in settings.toml?

[unreal bay]

theres a good question

so in theory if the editor.py thing happens, and the usb HID keyboard input device is a serial stream device (or something) as planned, then you could have a way of updating the password line or hiding it as part of the editor

i don't actually use REPL as REPL, only use it for serial prints and debugging

I've only ever needed to use REPL like twice for something very basic.

[unreal bay]

only when you broke something or forgot something

[sand lotus]

Recently with openskynetwork they require base64 encode. Would be cool to have everything in settings.toml automatically encoded somehow so nothing is actually stored in plaintext.

It's very basic encoding but could be a neat feature.

[unreal bay]

Apart from showing onscreen, think of it like "if the device is in their hands, they have your password/keys"

[sand lotus]

yeah true

[tiny grove]

And encoding provides zero protection.

[sand lotus]

was thinking more of like accidental github commit kind of thing.

[unreal bay]

saying that, I love wpa_supplicant.conf from linux wifi config, and they love encoding the passwords, but you can use plainttext if preferred

[sand lotus]

though anyone worth their salt would be able to disect it in like 2 seconds. just a thought.

[tiny grove]

In that case the only viable option would be to immediately change your password.

[unreal bay]

the bots love base64 too these days. About 10years ago a site I visited started double base64 encoding things to avoid simple bots

[tiny grove]

Wow ok that's dumb.

[sand lotus]

yes, i've had to do that. shipped out the 7 segment display to someone and forgot to change my settings.toml and had all my tokens for everything. everything was changed by the time it arrived to them in the mail, it was just a hassle.

[tiny grove]

Also I believe wpa_supplicant.conf might support password hashes. If it's a (salted) hash it should be fine.

[unreal bay]

sssshhh, that double protections still working well

[sand lotus]

if you hadn't been around for the older build differences you would have been really stuck

good refresher to do old builds because stuff like this will likely come up again

[unreal bay]

have you looked at LVGL projects in Squareline Studio, similar notion (json).

[sand lotus]

displayio turned into lessons on builds, git, and bug hunting which is just as good to learn as anything else CP related.

[unreal bay]

can I signup to beta test please 🙂

[sand lotus]

updating 8.0 code to 9.0 is going to be a big project all around for all libraries and most aspects of CP.

[unreal bay]

Thanks, have a nice day all

Hi, all!

@open girder Of course the Taylor Swift tune is perfect. But you could load Adafruit tunes on for safer YouTube demos?

So did babyada actually calm down? 👶

[covert crag]

Have you checked/got the boost converter going into an ultra low power state?

I need to calm down, too. Just came from a party and kind of over the stimulus. Love chilling out on with Desk Of.

Yep. No shame about using tools like ChatGPT. Or StackOverflow. Or Google.

[slow spire]

Interesting; yeah I guess I do use ChatGPT kind of like search.

[covert crag]

Currently being a low power nerd and refactoring some things to use ESPNOW with a relay to improve sensor node battery life by many times vs directing connecting to WiFi, so I'm very much in optimise all the things mode 😉

https://tenor.com/view/the-road-to-el-dorado-both-both-is-good-gif-8304204

Are there any buck/boosts that can be set to disconnect when the input voltage drops too low? Asking as with NiMHs you generally don't want them to go below 1V each as it can damage them, or would you need a voltage supervisor as well for that?

[open girder]

@covert crag don't know one off hand, but check out uvlo in the datasheets for the part, that's the under voltage lock out

[viral sail]

Thanks @open girder and good night. 🌓

[verbal river]

Bye

[slow spire]

Thanks, y’all!

[mellow arrow]

I didn’t see if you ever got a reply.
While I like the generality of the seesaw library, I wanted the attiny1616 to do as much heavy lifting as possible so I went down the path you suggested and created high-level commands rather than granular commands for individual LEDs. It has he advantage of being fast with low I2C bandwidth at the expense of codifying functionality into the attiny1616 device.

oh sorry I put that sleep_ms(2000) in the code Scott 🫠

[rapid hornet]

I've been looking for it

[proven crow]

Hi all! Sorry I'm a little late to the party.

[rapid hornet]

@cinder wind I was just talking to jepler around usb host and he mentioned midi....

[inner spade]

@split gazelle Really cool hack! Like the way it fits in the original enclosure.

[cinder wind]

yes! there are a couple of tinyusb PRs that work pretty well for USB MIDI host. They're both waiting for some API changes I think. I cannot wait

[split gazelle]

thanks @inner spade !

[rapid hornet]

I haven't been planning on using the class stuff from tinyusb

though I am for "built in things" like HID

[nova totem]

@sand lotus That's a great idea and project. I did think about mounting an antenna once

[sand lotus]

for weather sensors in direct line of sight will work very well

Early Question for @open girder Ask an Engineer (I might not catch it live tonight)
What are you thoughts on the Uno R4 minima and wifi, and when will it run CircuitPython?
Thank you

[rapid hornet]

@cinder wind sorted it out. looks like I wasn't scheduling the usb response code often enough

[open girder]

@tulip canyon we have one, was part of the beta (sorta, long story), will show off some stemma things that work, and we're interested in porting circuitpython, but maybe we'll ask renesas to help with that 🙂

[tulip canyon]

I keep hoping there is someone out there with a warehouse full of toilet paper from the pandemic. 🤣

I saw a tee shirt recently that said “I used to be a people person, but people kind of ruined that for me.” I wish it were not so true. 🙁

[slow spire]

“This week on Pandemic Hoarders…”

[sand lotus]

professional price fixers should just get into the stock market and gamble on publicly traded companies and get mad at them. adafruit's got nothing to do with that.

Kattni ❤️ is awesome, so is AnneB. pretty much everyone at Adafruit is awesome.

[cinder wind]

awww blush

[sand lotus]

including Todbot <3.

[dim wigeon]

The Adafruit community really is fantastic. If there’d been more community like this when I was younger, I wouldn’t have waited so long to pursue my interest in hardware.

[austere pollen]

New RP2040 successor confirmed? 😝

[nova totem]

Can't agree more. I went from a curiosity to being literally surrounded by controllers and boards and wires now

[distant junco]

You think it's a new chip RP2040 v2? Or just a different board shape?

[sand lotus]

dual pico rp2040 with dedicated dvi? i'm down for something like that. more ram pls.

[distant junco]

I would KILL (not really) for a RP2040 that supported better low power settings

[austere pollen]

let me dream, ok? 😄 I would like a new RP2040 except with more RAM and more PIO. Like imagine having enough PIO for USB + DVI

[austere pollen]

that too

[dim wigeon]

Same. I ran into so much gendered bull**** about hacking hardware in my 20s/30s that scared me away for DECADES. It makes me sad now…but I’m glad that people getting into hardware now don’t have to deal with that gatekeeper-y nonsense.

[austere pollen]

and faster clock speed, although the 133MHz of the RP2040 are kinda a "scam" if people can just overclock it to what 500? 😆

[distant junco]

that would be great... especially if they can keep the chip at the same price point

[dim knot]

https://www.adafruitdaily.com/

[slow spire]

Are two RP2040s an option for your project idea?

[sand lotus]

not sure how that would work with a pico W since that takes up a bit of room

[dim knot]

https://learn.adafruit.com/guides/latest

[sand lotus]

ohh and a RESET button please

[slow spire]

Love this music!

[sand lotus]

beautiful music yes

[slow spire]

Anyone know which track this is?

[distant junco]

you know those 4 hour yule log videos that you see in December? I feel like we need 4 hour pick and place videos

[sand lotus]

i'm sure it's copyright free after last weeks fiasco with YT content id smackdown

[austere pollen]

For my current project PIO is definitely enough. Ram probably too. Just maybe I need more processing speed. Hardware float multiplier would be really nice. Though I haven't really looked into overclocking yet so that might also be fine.
Just out of curiousity I've looked a bit at PIO USB, PIO DVI and so on but that's not actually relevant for me now. 😄

[sand lotus]

i got 2 metro m7's and have yet to even use them been so busy with other projects 😦

[austere pollen]

But like I always want better hardware 😆

[sand lotus]

i love JP headroom, it's perfect

[austere pollen]

that bouncing ball was rendered on the rp2040 🤯

[waxen bough]

Nice 3d packaging for that DVI feather!

[sand lotus]

i think PhilB did that, it's great, nice job PhilB!

[tulip canyon]

It's got a bit of a medical aesthetic

[slow spire]

Maybe adding something like an Itsybitsy M4 Express to give you an FPU?

[austere pollen]

honestly, the "best" option would probably be to just switch to a teensy or another faster than RP2040 MCU in case performance really isn't enough😆

[sand lotus]

well the Metro M7 is in that family i think?

[cinder wind]

yeah I'd really love an M4-class (with FPU) version of the RP2040. Even if it was assymetric, with one M4 core and one M0 core.

[austere pollen]

seriously yes! slow core + fast core with FPU would be absolutely perfect for my current project 😆

[sand lotus]

must have wifi though, i can't live without adafruit_requests projects, most of the time.

like the m7 with an airlift is great

dual rp2040's with pico w wifi would be nice for pico dvi + wifi

something like that

[austere pollen]

looks like it could also be a good option for my project if I have to give up on the RP2040 because of performance. 👍 thanks for mentioning it here 😄

[cinder wind]

every time I open up the rp2040 datasheet and see this section, I can help but imagine what they got cookin'

[sand lotus]

ohh didn't know that

[austere pollen]

RP8799 plz 😝

[sand lotus]

basically an RP4482?

i'd be down for that

[slow spire]

RP8086 🙂

[wild urchin]

Isn't it in the chip companies' interests to make it simple for people to develop on their chips?

[verbal river]

On my current RP2040 project, I just kept hacking at the code until it ran fast enough. 😄

[sand lotus]

no idea how/where the pico W wifi factors into that, it's a separate wifi module

[austere pollen]

Just curious, does DigiKey sponsor adafruit or something like that?

[cinder wind]

The rp2040 datasheet just covers the rp2040 chip, not the Pico board (e.g. rp2040 is on both Pico & Pico-W)

[open girder]

yep! @austere pollen they work with us on a bunch of things

[austere pollen]

neat 👍

[sand lotus]

the great search is sponsored by digikey for example

[austere pollen]

thanks for the answer 😄

[slow spire]

Now I’m picturing a baby toy version of this ST link

QUESTION: ADABOX?

[wild urchin]

Question: Recommended lead-free solder?

[austere pollen]

I haven't tested many. Personally I like the solder with a lot of silver (like 3,8%)

[brazen quail]

What is fastest quad encoder board can go ? MHz ? (Before edges dropped)

[turbid hill]

60/40 lead/tin solder does not spew fumes of lead, the fumes from solder are rosin in the solder

[proven crow]

Q: When you have a gut feeling that there's problems with a PCB you've designed and haven't ordered yet, but can't see any obvious errors, what do you do? Spend hours looking for a potentially imaginary problem, or YOLO it and possibly waste money? Thanks for all the work you do with OSHW, you're truly an inspiration.

[austere pollen]

@open girder thanks for the answer. I'm just so sad because I honestly like arduino very much 😭 😄

[turbid hill]

lead solder is easy to work with, lead free can be a bit temp tricky to use
