[cinder wind]

USB Host mode is still kinda janky I think 🙂

[teal river]

I love so much that new NES games are still being made

[lavish patrol]

Of course - the obvious question - will it run Doom? 😄

[teal river]

Yes https://blog.adafruit.com/2022/03/15/doom-running-on-a-raspberry-pi-pico-raspberrypi-raspberry_pi-kilograham5/?gclid=EAIaIQobChMIue7Yh7Kx_AIVFJXICh3NNATCEAAYASAAEgJIivD_BwE

But can it run Crysis

[lavish patrol]

Lol

[teal river]

It's wild how easily we can emulate things that were expensive 30+ years ago

And hard to make

Gotta print an NES case

It would be perfect to get a little OLED and put it into a tiny handheld themed like the NES

PS1 on a Pi 3 or 4!

[shell mason]

think Lars game for pico NES

[teal river]

Put the Pico in an NES cartridge

[smoky island]

you could embed it in the LEGO NES build so it becomes functional 😄

[teal river]

lol

[cinder wind]

Put the Pico in an Atari catridge running the NES emulator

[teal river]

RIP mushroom

How hard would it be to get this working with an OLED or TFT?

I want most of the LEGO display kits... but I have no place to display them and no money XD

I know the CPU in the Pico is waaaaaay more powerful... I'd guess that the Pico has an excess of power compared to the whole thing

Oh, Pico can do composite out with a little work, right? Could use tiny composite LCDs

Ah, this is what I remember about Pico composite... https://areed.me/posts/2021-07-14_implementing_composite_video_output_using_the_pi_picos_pio/

There's a giant CRT I want to take home from work, it's like... 40"?

45?

BIG

[teal river]

I HAD THAT TV

It exploded

I have one of those Radio Shack RF modulators!

[lavish patrol]

Antenna pass-through, @haughty quiver ?

[teal river]

Antenna input is so you can pass thru your antenna signal

[lavish patrol]

I concur.

[teal river]

I know this because I had it XD

Have it

Now on a shelf unused, lol

[inner spade]

Mixes VHF RF signals.

[teal river]

Yeah, it auto-switches

Great show!

Hey Tim!

[magic grotto]

Apologies if you addressed this already, but is the circuit board something that is available for purchase or on github to play with it on KiCad by chance?

[magic grotto]

thanks

[upper sandal]

you can put the actual update into a synchronous function, that you can call out of order

but you might not want to

I don't know the architecture of the code 😛

you could use Thony or a picow with Web Workflow 😉

[wind spoke]

Sorry, I missed the start, what is your display this time?
A Feather S3/S2 TFT?

[upper sandal]

though my app didn't work 😦 did you try updating node since ?

hmmm that would be a bug ?

did ejecting from the file browser do a real unmount ?

yeah it shouldn't care about the drive status

[inner spade]

Yes it’s working. About +/- 1/4 step-ish

Could put a slider on a pico analog pin.

[sand lotus]

modwheel and pitchbend on instruments are generally done with wheels

it's why i started designing the enclosure with modularity

specifically to add joysticks for pitchbend and mod wheel

https://www.adafruit.com/product/2765

Was on JP's product pick of the week a month back and picked up 10 of them and the breakout boards to go with them. So they will just mount to a modular bay faceplates with some mounting screws.

Was trying to get a prototype enclosure printed and to you before you got to that point but ya beat me to it, sorry. 🙂

[smoky island]

Would staticmethod be needed if other shapes use polygon to draw lines?

[brazen chasm]

Excellent topic today. I have had problems with sparklines being full, and memory alloc error. This PR references an issue i took up a long time ago. Lets see how big you manage to make a sparkline!

Also since working with these this week, i have noticed that the y min and max are not reset in clearvalues(). Im gonna make a pr for that later…

[sand lotus]

👋

sorry missed the stream last night. was up all night working on 3D modeling and slept the entire day

was a great stream though. completely awesome stuff.

well you knocked it out of the park, even the UART stuff from a built in display on a different board was extremely impressive.

like, i didn't even know that was possible

same with JP getting DVI working from a Pico, learning so much lately i didn't know was possible.

thought that was a custom UF2 so it's not exactly universally easy to just use DVI. i'd love to be able to pipe the display for a sequencer to HDMI.. that would be neat

looking forward to seeing what cgrover does with the waveform thingy he's working on, no idea what it is but sounds neat.

well i think JP said it was DVI but running on an HDMI cable. it worked though, regardless if it's DVI if it's on an HDMI cable might as well be HDMI. if it works it works.

[lilac tusk]

It’s a licensing thing rather than nomenclature

DVI and HDMI are essentially equivalent. One requires you pay a standards body for the privilege to use an acronym, the other is the open standard

[inner spade]

Three module mock-ups. Wave generator is top right.

[lilac tusk]

HDMI is slightly more complex but not enough to pay for the privilege to use HDMI

[sand lotus]

seemed like he didn't want to say that or the word nintendo because reasons. i really dislike having to tip toe around nomenclature like that it's just silly.

[lilac tusk]

That’s capitalism for ya

[sand lotus]

jesus cgrover

[lilac tusk]

It’s okay though, DVI loves us and doesn’t charge us money

[sand lotus]

displayport is better than hdmi anyway

[inner spade]

Yes they’re actual size prints. I usually start with the panel design to verify the needed functionality.

[sand lotus]

might have been vecterio bug hunt that cgrover found? i think you were on that for a week or two.

[teal river]

HDMI is like DVI+

[sand lotus]

i just use the github search

https://github.com/adafruit/adafruit-circuitpython-weekly-meeting/search?q=vector

yeah now cross reference the date with videos around that time

find the playlist for deep dive?

play the playlist, they SHOULD be in ascending order

however the adafruit youtube needs a lot of work because some playlists are not in order

[lilac tusk]

I said essentially the same, but I won’t say exactly the same. But it’s the same enough where most people wouldn’t know the difference unless the dove deep into the standard

[sand lotus]

there are 2 ways as a YT content creator to order playlists. by date the video was added to the playlist or the date the video was originally published

and adafruit has most playlists set to date added to playlist which is a bad idea for a long running series with dates in it.

[teal river]

Yeah XD standards get weird sometimes

[inner spade]

I needed vectorio arcs for a widget project a while ago. Used some creative workarounds instead. https://github.com/CedarGroveStudios/Widgets

[sand lotus]

i feel like you should have a segment in each deep dive called "hello future Tim" at the end where you give a brief summary of what you worked on

magnetic connectors on headphones are amazing, just saying.

would rather have it disconnect the power input than yank my neck backwards or worse, rip the code out of the headphones.

when adafruit started selling them i bought a bunch and they're awesome, specifically for avoiding the headphone yank or picking up a tablet that's still connected and getting a yank on that.

https://www.adafruit.com/product/5520

tips sold separately depending on which one you need

oh you're using 3.5mm?

https://www.amazon.com/Adapter-External-Converter-Compatible-Desktops/dp/B099FLWJD3/ref=sr_1_3?th=1

combine that with the magnetic cable and should stop the cord yank

i had the same question, no clue... but it's a thing apparently?

maybe some type of float or rounding error?

i like how you're starting to switch to printf's, sets a good example and reinforces that everyone needs to start doing that.

[inner spade]

I think rounding a negative value increases the absolute value: round(-3.6) = -4.0

[clever summit]

🇸🇪 👋

[inner spade]

Yes - 4.0

[upper sandal]

the nearest

[clever summit]

Was a good podcast!

[sand lotus]

i haven't seen it yet, will go watch that after your stream for sure.

[clever summit]

It is a sound only podcast so not much to see. 🙂

[inner spade]

Except the rotating logo, which was pretty subtle.

[clever summit]

Which also means it is available on Spotify, ITunes, etc.

https://open.spotify.com/episode/5C53B2srF4bfljIv0HZlTu

[sand lotus]

I'm already subscribed to them on YT. I listen to most podcasts on YT.

technically i watch podcasts 😛

[clever summit]

Yeah, me too actually.

[brazen chasm]

you have the y.top and y.bottom also

y_bottom and y_top

[sand lotus]

both? that's not confusing at all.

[brazen chasm]

a couple of days ago i think i found a problem with having 0 as y_min (or max), because the line ``` if self.y_min is None

[sand lotus]

None isn't the same as 0 though right?

i guess it could depending on context?

[brazen chasm]

can this really be true? that an float that is 0.0 triggers ìs None?

[sand lotus]

0 isn't always necessarily false though

[brazen chasm]

i got it to work with ```
if self.y_min is None:
self._redraw = self._redraw or value < self.y_bottom
self.y_bottom = value if (not self.y_bottom and self.y_bottom!=0.0) else min(value, self.y_bottom)````

in the add_value

[inner spade]

The use of None for normally numerical values can be tricky, for sure.

I usually avoid it when possible.

[sand lotus]

When using numbers I specify the if numerical value and avoid None like the plague.

[brazen chasm]

yep, the realesed one

[clever summit]

I tend to avoid None in production code. Just use "" and 0 (sometimes -1) instead.

It just makes code more complicated.

[upper sandal]

nothing is ever equal to None except None

[brazen chasm]

just added the self.y_bottom!=0.0

[upper sandal]

unlike booleans where everything converts to False or True

[sand lotus]

Well the other day I saw you using -1 for some of the cowbell stuff but that was within the scope of a variable and not specifically numerical calculations.

for calculations i'd avoid using None.

[inner spade]

None is great for showing when a value hasn’t been specified or is invalid, like when a sensor isn’t finished with a measurement. Just have to be sure to document it clearly.

[sand lotus]

I prefer None with booleans only. maybe that's just me and why i'm still not that great with coding.

[upper sandal]

using None as a way to mean "not specified" or "undefined" works, but requires to make sure that you test it at every point where it could be None

also, not with booleans (because while nothing converts to None, None converts to bool)

[inner spade]

None in Python is like open collector (open drain) busses in hardware. 🤔

[upper sandal]

what ?

[sand lotus]

None like dev/null 😛

[inner spade]

High impedance, absence of a signal.

[sand lotus]

yeah None can be tricky

always depends on what context you're trying to feed into it

[inner spade]

None: “Move along, nothing to see.”

[upper sandal]

it really doesn't depend that much

[sand lotus]

yeah i use it a lot with JSON parsing when banging my head against 0auth walls

[upper sandal]

actually let me correct myself, False is equal to None, I was more thinking of numbers

actually let me recorrect myself, I meant None converts to False

that is to say bool(None) is False and if None: is the same as if False:

[sand lotus]

yup and if the context is expecting a boolean then it will be false instead of a number but if 0.0 is a valid number then that might not = None.

[upper sandal]

a number NEVER equals None

[brazen chasm]

try adding a 0.0 and then a higher value, y_min will not be 0.0. i think i remember correctly

[sand lotus]

then why use 'if value is not None' instead of 'if value'

if a number never equals none then checking for none becomes redundant?

[upper sandal]

if value tests if the value converts to False, like 0, [], None
if value is not None tests it the value is anything but None, like a number

[sand lotus]

ah

[upper sandal]

typically if you want to have a default value for a parameter to a function where a valid value can convert to None

[sand lotus]

because it can't be None that's what ensures it is a number. 👍

[upper sandal]

def func(x=None):
    if x is None:
        x = 3.1415
    print(math.cos(x))

func(0) and func() give different results

whereas if you tested if x: they would give the same result

[sand lotus]

neat, seems like a good way to set a default value for a function too

also a way to have a function fail gracefully with a set value instead, kind of like an error handler.

[upper sandal]

sorry if I'm being confusing

[sand lotus]

i am following, good example.

[brazen chasm]

y_top and y_bottom i ment. sorry

[sand lotus]

interesting idea. wouldn't you need to change the names of the classes if you import. wouldn't those conflict unless you use appends for everything.

yeah but even if they were getting clipped it shouldn't have caused the script to crash.

[brazen chasm]

oh, yeah, im also talking about the case when y_in and max are not specified,autorange that is.

[sand lotus]

in some situations it might be beneficial to show it dips below the chart (and not displayed) instead of substituting a 0.0 value (as it's currently doing is a good thing). like i could see that being useful depending on what the intent of the graph is.

what i'm trying to say is i like the way it's behaving, looks good to me though i don't know what the intention is.

yeah problem with that is having an invisible part of the graph, like everything should be on a graph, even if it's in the negative.

like x,y should always show negative values

yeah i changed my mind.

if you're going to display a graph there's no point in having anything invisible unreadable.

because what if it stays below... you can't see it.

[inner spade]

I also prefer the phantom point. Sometimes the slope of the line is meaningful, particularly when wanting to see velocity when plotting distance.

[sand lotus]

data integrity is good but interpolation has its place too.

[brazen chasm]

phantom!

[sand lotus]

with such a small device, probably best to have data accuracy because these small microcontrollers aren't the most powerful or accurate devices as it is anyway.

[brazen chasm]

what happens with 2 negative values in a row?

[sand lotus]

so if becomes invisible then it's a user configured problem and needs to be reconfigured.

didn't realize it worked that way, yeah just have the user reconfigure it so everything is visible.

like working with an oscope where something is out of range

you have to adjust the scope

[inner spade]

And sometimes you may want to zoom in on a few points. Phantom points are essential in that case.

[sand lotus]

in docs i kinda figured the dyn_whatever property would do that dynamically?

this is actually really cool stuff. can set a high/low trigger and capture waveforms

maybe dyn works within display height/width for bitmap?

very interesting project, looking forward to seeing more of that

[inner spade]

Fantastic stream today! Brain cells exercised.

[sand lotus]

Documented a hardware bodge fix for the tr-cowbell. not sure if you've seen the posts about it.

recommend doing the fix https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Boards/raspberrypi/Raspberry Pi Pico/TR Cowbell/v1.2 Hardware I2C Bus Fix

2 traces to scrape away/cut

yes, puts both on bus 0

frees up stemma

and the entire bus 1 is free yes

i solder the stemma connector by hand, yes it's tiny but possible.

the video is very long

thank you for the stream, always something new to learn

[clever summit]

Thanks! Have a nice weekend peeps.

[teal river]

Is it hard to know exactly where to put the cutout?

[strong acorn]

w00t

[empty swallow]

I'd say there isn't anywhere you need to do it, other than in the area the flex cable will be

[teal river]

Ohhh

Have you ever done Eagle tutorials? I installed it and tried playing with it, and... I have no idea what I'm doing

[ashen hound]

would using a ZIF connector for the TFT display make it expensive?

[empty swallow]

How will the new chip change the code for using it?

Even just in the library back-end?

[teal river]

I agree with making ALL the changes at once

[verbal river]

@proper trench I like the tact-switches-with-bigger-buttons you showed last week. I've pressed RESET+BOOT_SEL 170000 times recently on my Feather RP2040, making them less fiddly is a good idea. 😄

[empty swallow]

My baby is 10 months though 😳

Gave him a nibble of ice cream

[open girder]

6 weeks old 🙂

[lilac tusk]

The stage of “will I pull my hair out or will it fall out first” 🙂

Mostly due to sleep deprivation

But also sweet coos make things better

[cinder wind]

Eagle is abandoned. If you're just getting started in drawing schematics & pcbs, a better option would be KiCad

[teal river]

oh

[lilac tusk]

They still update Eagle

It’s just ya know.. $60 a month if you want to do anything more than 2 layers

[ashen hound]

abandoned as in they are not actively developing it?

[green bison]

It's all moved to fusion

and is neglected there too

[cinder wind]

Yes. the last update to Eagle was in 2020. Autodesk is still improving their "Electronics" view in Fusion 360, which works a lot like Eagle but it is not Eagle. And in many ways it sucks

[green bison]

It's really not that good

[ashen hound]

I tried using it in Fusion more than a year ago. It was very confusing and I gave up.

[lilac tusk]

Weird, I thought I had got an Eagle update recently . Oh well

It still very solid functionality wise

But KiCAD is still probably a better tool to start with given the points above about it being actively developed

[teal river]

KiCAD is free?

[lilac tusk]

Oui

[fossil spear]

Has anyone tried flux.ai ?

[teal river]

yeet

[ashen hound]

Does KiCAD integrate with mechanical CAD like SWX?

[green bison]

kiCad is about to release kiCad7

they released kiCad6 this time last year

[lilac tusk]

It’s okay, just a bit weird ui wise

[green bison]

Super active development.

[lilac tusk]

No idea

[green bison]

Meanwhile fusion has had no improvements

[green bison]

99% sure you can make STEP files

[lilac tusk]

Except for SAMD chips

Boo..

[ashen hound]

awesome!

[green bison]

One of these days I'll learn kiCAD and switch over. I'm just so used to FEAGLE

Good morning ☕️

[brazen chasm]

Good evening

From Sweden

[sand lotus]

In GitHub if you go to the example and choose the raw format it removes the line numbers. Easy way to find example code without needing to do that. Same with a lot of examples in learn guides that include the REPL >>> characters. Newbies aren’t going to know not to include that when copy/pasting.

[inner spade]

☕

[sand lotus]

oof

i mean you could write a script to use regex to detect line numbers and remove them but good luck with that. being able to specify a version number and have it automatically update everything to without line numbers seems a much more appealing fix... if it's that simple.

yup left lower and right lower halves. printing the right lower half as we speak. it won't be finished for another 14 hours. :/

it's in PETG, very dense material with 1.2mm layer heights, high quality. comes out feeling a bit like legos except not perfect sides like legos. it's heavy too.

haven't tried printing a lego but bet i could make a semi-convincing replica just with the 3d printer. kinda like the orange step switches, from far away you can't tell they're 3d printed versions.

oops you're right it's .12 mm not 1.2

Ender 3 S1 pro has an auto bed leveler switch that creates a super precise bed mesh so i can do stuff that close with almost no experience.

i've never seen assert used before, didn't know that existed.

assert could get changed or deprecated someday but an if statement will always be valid

just the word assert is more characters so could see that being less space efficient, if bits matter then if beats assert?

should link to the learn guide for that one, like the learn guide shows exactly how anchor and font positioning works. it's a great guide, i refer back to it all the time still.

That kind of thing is why I avoided MatrixPortal and PortalBase. It was a headache to deal with... hence why I started the API examples with the requests library instead. When the helpers aren't very helpful then they become unhelper libraries.

I get that the device and library are intended to make things easy and they probably do... just not to a beginner. It actually makes things harder for a beginner.

[inner spade]

I have mixed feelings about the abstraction provided by those libraries. Matrix Portal’s is so large that ulab was removed from the image.

[sand lotus]

Yup that's why I don't like it. You start with MatrixPortal, something doesn't work, then you end up diving into Portalbase... and things just go downhill quick as a beginners eye start to glaze over with the amount of stuff required.

[inner spade]

And it creates divergent ways of doing the same thing. Though to support in the long term.

[sand lotus]

you didn't know the ctrl+shift+alt+command+numpad0+F key trick? everyone knows that... (sarcasm)

yeah if you want to do internet based stuff it's good at that, like that's what it was designed for... but it's got its hooks into everything to do it

ohhh a custom UF2 builder GUI sounds really neat

[inner spade]

The Make-A-Bear approach to building an image. Nice.

[sand lotus]

true, i literally had to install WSL Ubuntu just to make a custom build

[inner spade]

Custom builds also have significant downstream support issues, though.

[sand lotus]

yeah like buying an expensive S3 just to find out there's no bluetooth in CP like it advertised...

i got one before they actually put up that warning message on the product page.

no salty about it though because there's always wifi

[inner spade]

Yeah, but I’m not hard-over on any approach as long as it’s logical and well documented. I’ll adapt.

[sand lotus]

i'm sure BLE will make it to the S3 eventually and I don't have an immediate need for it. not when i started getting involved and saw how many issues the S2 and other chips were having that needed priority developer attention.

what version is he on? wasn't there a memory leak with the matrixportal back on like 8.1 beta?

[inner spade]

Matrix Portal power requirements are so large sometimes (depending on what’s on the display) that seeming code issues are actually brownouts.

[sand lotus]

also if he's puling json and there's an error server side that error handling isn't catching then it'll seem like it's hanging when it's just an uncaught exception.

i ran into plenty of that when writing API examples with the requests library, that's the requests library though

not with the requests library, you have to add the try/catch yourself. yeah i imagine the matrixportal library has all of that built in.

all networks are weird somehow, every network kind of has its own personality.

within reason

why is it trying to create a DHCP server on a microcontroller, good lord.

why not just connect to the existing DHCP server on the local network?

you can't have 2 different DHCP servers within the same address range or you'll get conflicts. i mean for testing i guess it might work for a little bit but all the devices on your lan might try to connect to the dhcp server on the microcontroller.

i dunno create dhcp server is pretty specific language instead of connecting to dhcp server.

yeah it's not an AP it's ethernet hmm

that would make sense with an AP

but even then you'd want to disable DHCP on the AP

[brazen chasm]

my matrix crashes evero other week r s. im gonna look over my error catching, obvisously not enough. so i have 2 questions:
1.how to restart/reset
2. how to write the trace back to a file so i can debug? i cant have it in a comp for 2 weeks)

i use```````

  supervisor.reload()````

[sand lotus]

i think reset is different than reload

[brazen chasm]

or ```reset````

[smoky island]

https://docs.python.org/3/library/constants.html#None

[brazen chasm]

i have

traceback.print_exception(type(e), e, e.__traceback__)
print("Some error occured, retrying! -", e)

´´´
traceback.print_exception(type(e), e, e.traceback)
print("Some error occured, retrying! -", e)````

[sand lotus]

doesn't the matrix portal have an sd card built in?

or is this a different conversation and not about the matrixportal?

[brazen chasm]

ok, pyportal has SD card

[inner spade]

No SD on the MatrixPortal

[sand lotus]

ah

sd card breakout pretty cheap, the problem is trying to write to it after a crash, that sounds hard

like if it crashes you don't have access to do anything, no idea how you'd do that

maybe some external debugger?

which foamyguy has an awesome external debugging video out there now

[inner spade]

I finally resorted to wrapping an entire MatrixPortal project with a try/except code.py to deal with “the internet sometimes just fails” errors. (Like putting black tape over the VCR’s flashing 12:00 clock display)

[sand lotus]

i swear you had the wiznet working fine like 2 weeks ago...

maybe assert was catching something the if statement doesn't... seems unlikely

almost seems like some ctrl+d duplicate issue?

two identical lines is redundant, maybe one used to be the assert and it just didn't get folded into 1 if statement?

if it's under identical if statements then whatever is in them should be put into 1. just seems like a redundant statement that was missed.

and it's weird it was missed when the assert was removed

yeah same @inner spade, part of the problem with original requests library examples is the try/catch stuff if the internet goes down isn't in there. figured that one out the hard way and literally just started disconnecting the cable to the router while debugging internet down try/catch.

then put that in my code snippets on github so that would never happen again

[brazen chasm]

oh, can we see it? pleeease 🙂

[sand lotus]

i think +1 is part of the datagram packet, absolutely the way it should be... the +1 is for the ACK

[brazen chasm]

cant any ero

import supervisor
supervisor.reload()```

[brazen chasm]

i did that too, but it still fails. ill cant remember, have to look. so, catch any error

[sand lotus]

syn sends request, ack responds with syn sequence +1 as the syn-ack.

it's part of the handshake process

specifically, it's called the three way handshake

you might have to go back and watch past Tim's process

ah there ya go. aren't you glad you documented the heck out of it. brings up a great lesson about documenting the crap out of everything.

[inner spade]

I couldn’t get the supervisor approach to work with portalbase. I’ll post the code used in a few minutes.

[sand lotus]

ahh the PR never got merged? well now everything makes sense.

[inner spade]

If I recall, microcontroller.reset() after a try/except worked.

[sand lotus]

@brazen chasm https://github.com/DJDevon3/My_Circuit_Python_Projects/tree/main/Circuit Python Snippets#get-time-from-online-esp32-s2

it's part of an example where i get time from an online server

part of the try/except for not having an ipv4 address is in there

[inner spade]

"""Set FAILOVER to True to fail to a dimmed display and flashing NeoPixel;
False to fail normally with error reporting via the REPL."""
FAILOVER = True

while FAILOVER:
    """Attempt to start the primary code module. Upon failure, execute the
    failover module."""

    try:
        import matrixweather_code
    except Exception as e:
        import time
        print(f"matrixweather failover: --{e}--  at time.monotonic: {time.monotonic()}")
        import matrixportal_failover  # dim display, wait a bit, then reset the board
else:
    import matrixweather_code```

[sand lotus]

oh wow, neat

ahhh i see, nice switch

if the MCU hasn't crashed and caught the exception that looks pretty good

[inner spade]

matrix_failover is a module that dims the display, flashes the neopixel, waits a minute or two, then resets the MatrixPortal. It's extreme, but works nicely.

[sand lotus]

i see what you mean now about wrapping the entire thing. you weren't kidding. my try/except is very localized compared to yours lol

are there benefits to offloading it into a module for error handling?

[inner spade]

Yeah, a desperate approach. Couldn’t wrap my head around finding the error.

[sand lotus]

i mean i'm kind of doing the same thing just not from a separate thing.

yeah merge it, push it, if it breaks something you'll hear about it pretty quick?

[inner spade]

Not really except I have a specific failover module for different boards.

… to put the display into a low power state.

[sand lotus]

modularizes the code, though you do a lot more big coding than i do. i can see the need for it for you. i'm still small potatoes which has its benefits for relating to beginners for simplifying code that can be easily understood and modified.

there's a difference between copy/pasting stuff you understand and stuff you just pray works like voodoo magic and not much hope of understanding it anytime soon.

like the cowbell code tim worked on, gonna take me a looong time to comprehend most of it. i don't even know how asyncio works. lots of learning to do.

[inner spade]

I’m predominantly hardware-focused so I do both.

[sand lotus]

yeah neradoc

been looking into PIO and DMA stuff lately. after watching ladyada talk about PIO lately seemed like a good way to go

yeah state machine, PIO.

glad you got it all figured out, whew. that was an adventure.

[brazen chasm]

thanks Tim and all you other guys!

[inner spade]

A useful adventure for learning. Thanks!

[strong acorn]

in some cases, I'll try supervisor.reload first, and keep a count of successive reloads in alarm.sleep_memory, then if there are too many in a row do microcontroller.reset phew

[brazen chasm]

good idea! whats the difference in reload/reset? memory cleaned i guess in both?

[inner spade]

Wow. An interesting approach that’s got me thinking…

[strong acorn]

@brazen chasm There may be differences per port (board family), but I think this is generally how it shakes out. In both cases, code.py restarts, but onboard RTC is retained. I'll edit this post later if I find other differences.

supervisor.reload():
• "equivalent to hitting Ctrl-D at the REPL"
• alarm.sleep_memory is retained
• supervisor.get_previous_traceback() is not reset to None

microcontroller.reset():
• almost like pressing the reset button
• executes boot.py before code.py
• alarm.sleep_memory is lost
• supervisor.get_previous_traceback() is reset to None
• comes with a Warning:

This may result in file system corruption when connected to a host computer. Be very careful when calling this! Make sure the device “Safely removed” on Windows or “ejected” on Mac OSX and Linux.

[brazen chasm]

excellent stuff! thanks. im gonna write this down 🙂

but can you write the traceback to a file before calling any of these. that was another question. so that you can study an unconnected CPY and why it breaks (that led us in to the error catching..)

[strong acorn]

there's also supervisor.get_previous_traceback() (after reload, not reset) https://docs.circuitpython.org/en/latest/shared-bindings/supervisor/index.html#supervisor.get_previous_traceback

[brazen chasm]

super!

[ornate bay]

Is that... CI?

[sand lotus]

Getting a double dose of FoamyGuy today. Nice.

What would happen if you already had a fork and forked it again? Would it let you do that from github?

would it just create a new branch or ask you to create a branch or something?

thank you, just making sure it's idiot proof so i don't accidentally wipe an entire existing repo with a duplicate.

[clear matrix]

Even if you try to clone the same repo locally, it will complain that the directory already exists. You'd be hard pressed to wipe out a repo without heading into the Danger Zone in the Settings tab.

[ornate bay]

You mean the PR branch?

[clear matrix]

Whaaaaaaat?! How did I not know about this! Nice.

[sand lotus]

@strong acorn wow, didn't know that either. that sounds very useful!

[ornate bay]

It was older, I forgot too haha

[brazen chasm]

ah yes, i think ill take a double shot of Tim as well

🇸🇪

[ornate bay]

I thought the theme was up to 1.0.0

[inner spade]

Double grande

[ornate bay]

What we were using, that is

I think it's order based

[sand lotus]

makes sense because it says requirement satisfied

figure out a way to get the new version to apply first, not sure if that's a thing.

[ornate bay]

You can use == with it to force it

If it's after the other thing

Mmmm, I don't think so.

Let me check the pep

(PEP 440)

You could use a compatibility release specification I guess?

If you know the minimum version you'll need

Or minimum

The steps are there, they're just substeps now

[sand lotus]

Nice.

Oh you just scrolled past something like ignore_installed, could you use something like that to ignore the installed version?

Was something on stack overflow

Isn’t fighting the same issues from 10 years ago what Linux is all about though.

[upper sandal]

🤞

are they saying that they can manually enable USE_SPHINX_LATEST on a per repo basis ?

like an act from the gods of RTD ?

or did they add the feature to users ?

[sand lotus]

From what I’m reading pep386 uses loose versioning so anything is a valid version number. Unless it’s using strict. The way it knows what version is the latest seems to be part of how it interprets version numbering. It tracks the previous numbers and automatically figures out the latest based on that. However if it’s on the old system then it’s like the Wild West for what it considers the latest.

There’s gotta be a way to migrate. They wouldn’t just leave people out to dry like that.

Kattni said yeah everything should be the same versioning, not having it the same invites way too many future problems too.

She said during in the weeds. I don’t know anything about the versioning but I liked how she had a clear directive.

[upper sandal]

did they mention deleting the project on RTD and recreating it... which we don't want to do of course

fingerless gloves crossed

[inner spade]

May be time to rethink how to auto-create documentation. "Hey ChatGPT, create a UI document in the format of ..."

[smoky island]

It was not an official or scheduled stream. I popped on my own stream for an impromptu one for a bit.

[brazen chasm]

is there a way to check if my CPY is connected and take different action, to avoid the file corruption?

[strong acorn]

there's supervisor.runtime.usb_connected & supervisor.runtime.serial_connected

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

[brazen chasm]

great. so which one to use to avoid file mayhem?

[strong acorn]

I think supervisor.runtime.usb_connected is more relevant. I haven't used it for that purpose though, so I don't know if it's 100% or if you'd need to add a timeout or something if for some reason CircuitPython thinks it's connected but it's not.

(waiting in a forever loop only until .usb_connected is False should work, but I haven't tried it)

[brazen chasm]

yeah, and of course, how to debug with no USB? (thats what led to the discussion about writing traceback to file before resetting)

[strong acorn]

web workflow 😉

writing to file needs SD or some external storage if the host computer is also expecting to be able to edit files on CIRCUITPY, and switching back and forth to which can write requires a reset and running boot.py

(nvm could work, but it's a good bit of data to pack)

since it's a strong recommendation to use an editor that auto-flushes edits immediately, the microcontroller.reset() Warning is for those edge cases where you may be editing code while code is running and issuing a microcontroller.reset(), or perhaps something else on your host computer is pinging the CIRCUITPY disk (you may not know if auto-reload is off)

Rain slowing the packets down

[teal river]

Why might one get the C3 over the S2, S3, whatever other ones there are? [Aside from the awesome deal right now]

[cinder wind]

C3 can do BLE + WiFi and is smaller & cheaper, but no native USB. S2 is WiFi only + native USB. S3 is WiFi + BLE + native USB, but bigger and more expensive

(this is for the chips, not the QT Py boards)

[drowsy inlet]

Also, S3 is dual, S2 is single, and C3 is different chip, correct?

[tulip canyon]

Don't forget to update your

[cinder wind]

Yes, I think you are correct

[teal river]

Ohhh...

[dusk socket]

will it run circuitpython

[drowsy inlet]

i think C3 is arduino and micropython only, no? at least according to the page

[cinder wind]

(S2 & S3 are the Tensilica core(s) that Espressif has been using forever, so very well understood. C3 is RISC-V which is kinda experimental, but the future going forward)

[cinder wind]

"Yes, sorta" https://circuitpython.org/board/adafruit_qtpy_esp32c3/ but it's kinda hard to use since no CIRCUITPY drive

[sand lotus]

yup i've started adding the temp sensor modules on the exterior of any enclosures to keep it away from the board heat.

nylon good call, looks close to the pinout holes on the sensor module

i like how they doubled the edge connectors

the on-board temp sensors that come on feathers and stuff are a nightmare to calibrate if you're trying to use it for ambient temp, not worth the hassle, just use it to monitor board heat only.

because you have to account for how busy the MCU is, if it's sleeping, etc... it's just better to go with an external temp sensor module for ambient temperature logging.

I accidentally bought an ESP32-V2 which only ran micropython. Didn't realize it didn't run circuit python... but it will do wippersnapper. So wippersnapper is an awesome way to use legacy ESP32's with adafruitio.

You can use it with wifi workflow now, this was before that though.

[lavish patrol]

That's a lot of pixels...

holy neopixels. i didn't get a scorpio in time. definitely getting a scorpio or many of them sometime this year. will be awesome for Halloween projects.

[lavish patrol]

Lol. The lawnmower has been replaced by a cat. 😸

[sand lotus]

all of that is being powered only by the scorpio? what's the max power? kinda like most feathers around 800ma?

found the spec 3.3V regulator with 500mA peak current output

but can't the scorpio run at 5v so how much does that change the current output at 5v? ugh ohms law, i'm so lazy.

Good evening! I am here for S&T after all!

[inner spade]

👋

[waxen thistle]

Good to see ya Jeff!

[tulip canyon]

Wednesday is the best day

[teal river]

grrr bot

Hiii

[lilac tusk]

lol it was delayed haha

anyway, hi AdaFam!

[teal river]

Better late than never!

[nova totem]

Break time is over? hmm guess I should get back to something...

[lilac tusk]

yessss prams are so great

I wish we would have found a good one

they were all $$$

[tulip canyon]

The English left their kids in the yards in the pram

[lilac tusk]

oh very cool Erin!

I had some similar ideas but wasn't sure how it'd turn out

[waxen thistle]

Coin cell batteries are great for changing things up!

[lilac tusk]

glad to see they look really good in these applications

[robust horizon]

stablediffusion "goth pram, black and white photograph, looks like giant coffin on wheels"

[lilac tusk]

Batman pushes his children in these

[turbid hill]

reminds me of the old lady and the tram in ghost busters movie

[waxen thistle]

Next up, an onyx black escape pod turned into a pram....

[tulip canyon]

The nOOd cover seems really tough

[teal river]

Will the pram get electronic drive controls so BabyAda can learn to drive?

[viral sail]

great work @split gazelle ! I really want to try out the Pinquin tool

i have more reasons too now

[teal river]

11/10 cute boards

Jeff likes starting muted XD

[waxen thistle]

How one gets to Mordor to output to an HDMI monitor is a journey, best done with a fellowship of Hobbits Makers. And Hobbits too.

[delicate fractal]

Any recommendations for a portable monitor like what Jeff is using? (I could stand to go larger, too...)

[teal river]

I was thinking to do something like this with VGA

[waxen thistle]

https://www.adafruit.com/product/1667

There are several on the Adafruit store, that's the first one that's jumped out at me. I have that same exact one.

[delicate fractal]

Apparently, my search-fu sucks. I was seeing panels but not complete monitors when I looked.

[nova totem]

Very cool Jeff

@open girder the resolution list goes up to 1280x720 @ 30Hz

[alpine nova]

[waxen thistle]

It's a challenge to find a TV nowadays that's not internet connected -- aka a "dumb/non-smart TV".

[echo canopy]

That would be cool to display Adafruit IO on the TV with that boa

[haughty quiver]

Thankfully @waxen thistle none of my CRTs are internet connected 🙂

[teal river]

Sadly those are nearly extinct... the closest I've found is some LG models let you totally disable all that crap

[turbid hill]

original 5 slot PC, aka the ones with the faulty first slot closest to the PS?

[waxen thistle]

That you know of.....you sure no Cylons/Lars networked them?

Token Ring? That's a name I haven't heard of in a long time....a long time....

[cinder wind]

Tolkien Ring?

[turbid hill]

one ring to rule the network

[verbal river]

You need two of them so you can make a network.

[teal river]

I have a token ring of old machines XD

[delicate fractal]

Didn't you need a (probabbly quite expensive) hub thingy?

[turbid hill]

EMS memory

[waxen thistle]

One does not simply walk into Mordor without a Math Co-Processor....

[robust horizon]

@open girder there is a "dithered earthrise from the moon" example that can run at 640x480 @ 60Hz or 1280x720 @ 30Hz. The 720p version didn't work on my testing monitor but the 640x480 one did.

[turbid hill]

need to toggle protected mode

[delicate fractal]

EGA. That takes me back.

[upbeat coral]

RAM Disks with the extra mem

[gray obsidian]

You can still find packet drivers, look for FreeDOS… Oh there's a collection there: http://packetdriversdos.net/

[nova totem]

I remember trying to learn how to code for XMS or EMS memory (forget which)

[open girder]

ooh @robust horizon that is really cool

[turbid hill]

problem is 286 once in protected mode, you cannot get out of it without a reboot

[gray obsidian]

Is it @spring heath ? http://packetdriversdos.net/

[verbal river]

I wouldn't have thought so, but it is IBM so yeah I guess so.

[turbid hill]

XMS came with the 386

[alpine nova]

good practices in patience

[delicate fractal]

I remember the hubs handling things like dropped tokens and healing the ring...

... I think you needed a very special cable to do a DTE to DTE communications... I read a lot about TR, but never actually used it.

[lilac tusk]

The step switches are such a great thing to use for MIDI stuff

[teal river]

I blocked out a lot of token ring memories XD

[alpine nova]

wow never knew about channel 10

[teal river]

Hi, Tom

It looks clean but organic, vs. perfectly parallel and cornered wires

[alpine nova]

a lot of synth streamers on twitch claim no daw/all analog - by utilizing garageband, that would not qualify for dawless would it @haughty quiver

[cinder wind]

Sequencer looks so great JP! You should encase it in clear resin, leaving just the buttons & knob exposed

[teal river]

WatchSkerr time

[haughty quiver]

correct, this is DAW-ful

[waxen thistle]

Drum machines really push my buttons.

[alpine nova]

lol

thx

[haughty quiver]

this can be used without a DAW however if you have synthesizers/sample players that will either act as USB MIDI Host (such as 1010 Blackbox) or through an intermediary device to act as Host.

[inner spade]

I like drum machines with a kick.

[haughty quiver]

[nova totem]

Looks great @lilac tusk . Great to see the progress

[robust horizon]

that was a full show!

[waxen thistle]

Thanks everyone for sharing! You folks rock!

[teal river]

Imagine if we combined JP's synth project with the PicoDVI project

[viral sail]

Great projects everyone. Thanks for sharing.

[lilac tusk]

Thanks! I pushed myself to get it done for 2023 🙂

[tulip canyon]

Thanks everyone. Incredibly inspiring projects

[lilac tusk]

and now I have so many ideas on how to make it better

[alpine nova]

good to know. i use midi to trigger visuals and control mixing of vis but learning a lot about synth stuff the last year

[teal river]

Great show, great projects!

[inner spade]

Great SnT!

[waxen thistle]

That's no moon! That's.....wait, that's totally a moon.

Question from David earlier that I would also like answered!

[lilac tusk]

There are not terribly many decent 5GHz modules surprisingly

That should probably change with some of the newer ESP32 chips coming up though

[unkempt shoal]

I saw the RISC-V module, but didn't know if that did 5GHz WiFi

[waxen thistle]

I treat a cart like a flash drive or a floppy drive -- super handy, but not where anything should "live" for any significant amount of time, for fear of it disappearing.

Is this ESP32-C3 WiFi 2.4GHz or can it do 5GHz WiFi?

[waxen thistle]

When isn't it time for time travel?

[cinder wind]

just a jump to the left

[haughty quiver]

2.4GHz

[unkempt shoal]

Thanks.

Just 2.4GHz

[robust horizon]

I have at least 6 microcontrollers in arm's reach, how many do you have?

[nova totem]

None 😦 I made a horrible mistake and cleaned my desk. Wait no, one cause I'm bad at cleaning

[teal river]

Uhhhhh... like... 40? I don't want to pull them out and count XD

[lilac tusk]

I’m rooting for Matter support.

[turbid hill]

Jeff, Jeff, Jeff you ask how many MC are at hand. I have 326 of them cataloged in my stock.

[unkempt shoal]

Home Assistant support will be great!

[robust horizon]

Ok ok y'all got me beat by a wide margin

[lilac tusk]

Home assistant is hard, unless there was a way to do circuitpython to ESP Home

[teal river]

In arm's reach, lol

[turbid hill]

yes

[teal river]

Can you reach all 326 without getting up? :P

[tulip canyon]

Legend has it, there is a Jeff who’s done it

Is it Jepler? Maybe.

almost, there some that I have to stretch to get that are above my monitor in storage bins

I probably have at least one more lost under the couch cushion though

[turbid hill]

Lol that happened when a dropped a bin of sensors all over the floor

Arguably the BEST terminal blocks

Terminal blocks from wago are awesome -- I know of many professional electricians that use them.

[teal river]

WAGO, the ones everyone else copies XD

[waxen thistle]

And I have many of them for less-than-mains use.

[turbid hill]

Wago the preferred item for electricians in Europe

[robust horizon]

I always feel like screw terminals hate me

[waxen thistle]

Get the originals too -- knockoffs might not hold up as expected

[cinder wind]

Terminal Blocks?

[turbid hill]

[haughty quiver]

Any suggestions for using that camera with an Arduino and not a Raspberry Pi?

I need a tiny camera for an embedded project.

[nova totem]

ooo a raw sensor could be used to be mounted to a telescope for some astro photography. probably planetary given the size

[unkempt shoal]

I'd recommend the ESP32-CAM

[upbeat coral]

https://www.amazon.com/Arducam-Distortion-Lenses-Arduino-Raspberry/dp/B07NW8VR71

[ripe blade]

How easy is that to use with the SAMD51 or Teensy 4.1, for example?

[lilac tusk]

I did just get a telescope for my family for Christmas too 👀

[unkempt shoal]

It has its own microcontroller.

[nova totem]

Nice! What scope? I modified an old MS lifecam webcam that I know longer can get drivers for ha. And used my SLR for widefield

[ripe blade]

Hmmm...okay. I'll look into that then. Thanks for the tip.

[turbid hill]

There is a updated ESP32-cam called the ESP32-S3-Eye

[lilac tusk]

One of those run of the mill 114mm aperture, 500mm focal length reflector

It came with a 9.6 and a 26mm Plossl lens

[verbal river]

Just finished publishing my latest project, took all afternoon to document & upload, who knew a hobby would be so much work. 😅

[lilac tusk]

I need like 4mm and 6mm so I can see Jupiter better. My kids are thoroughly excited though

[nova totem]

Nice. Saturn, Jupitar and the moon are great targets to start on (depending when they're up). Saturn is still my fav.

[delicate fractal]

question for Ask-an-engineer: is it possible to control the exposure levels with the OV5460? I want to do some HDR-projects... It can be done with 2 cameras, but I've read of implementations that used one camera: they alternated between 2 exposure levels each frame, then integrated them to make an HDR image...

[lilac tusk]

We’ve spied the moon which they loved, and looked at Jupiter and saw 4 of its moons. It was tiny as the best lens we have is the 9.6mm

[nova totem]

Saturn is small but seeing the rings is unreal ( at least for me it was). Pleasdis is another good target, or any star cluster to see a lot of stars at once

[robust horizon]

@delicate fractal https://docs.circuitpython.org/projects/ov5640/en/latest/api.html#adafruit_ov5640.OV5640.exposure_value I think you can set the "exposure value", this doc says by whole numbers from -4 to +4 inclusive.

[waxen thistle]

Excellent reference quarter!

[teal river]

It would be cool if we could order those cool new quarters from the store

[lilac tusk]

I’ve read with the right setup you can spy a few galaxies pretty well. But that’s easily $200 in glass 🙂

Question @adafruit#3230 any plans to make a board with a IN100 NanoBeacon™ With a Stemma connection for sensors ? Seems to be very low power, low expense, and can be implemented with boards like ESP32 .. etc

[nova totem]

Andromeda should be visible. But galaxies due look kinda like fuzzy blobs regardless. Orion nebula in the belt is great too

[lilac tusk]

Question: have you received the NRF7002 Dev Kits from Nordic yet? If so, have you had a chance to try out the chip

[robust horizon]

it's not out yet .. but the source is open on github! https://github.com/jepler/PicoDVI/tree/spitft2hdmi but please don't ask for support
