Cool...looking forwared to holiday Discord

[ionic garnet]

NICE

love that

[slow spire]

Is that UNO compatible? Is it like the Adafruit Metro Mini 328?

[delicate fractal]

I used to work at BlackBerry. We once lost one of our power circuits when a squirrel shorted himself on a transformer.

[lilac tusk]

it's some limited edition Uno

marking 10 million unos sold

[upbeat coral]

Thank you for taking time for us.

[spiral bough]

You guys are the best!

[alpine nova]

happy holiday y’all

you guys are awesome!

[nova totem]

Thanks and happy thanksgiving to all my American neighbors

[atomic sandal]

Happy Thanksgiving!

[waxen thistle]

@open girder Thanks for another excellent evening of shows! Happy Thanksgiving and good luck this weekend with the Black Friday rush of sales!

[ionic garnet]

I really appreciate all of you who hang out here

[ornate ether]

Regarding the 6821 PIA, it looks like it's kinda similar to the 65C22 (although the register layout looks different). Data sheet here: https://sowerbutts.com/replica1-serial/6821.pdf If you haven't already, I'd suggest really giving the datasheet a good read, and working out, step-by-step, what bus signals you need to provide to do what you're trying to do. If you have some DIP switches, tactile momentary switches, and LEDs, I'd suggest breadboarding it all together and manually clocking it... setting the register-select/address lines and data bus lines and clocking through initialization and sending bytes. I wrote a simple program to do a nested loop and send incrementing bytes to both ports on the 65C22, which I then monitored with LEDs. You can throw together a simple 6502 ASM program (or do it on an Arduino) to do it, too. I think the tough thing is that the old Motorola parts (and old MOS parts) were not "static" and if the clock ran too slow (or stopped) they'd get all confused. I'm designing the RIBBBIT65 around the WDC 65C02 (and 65C22 VIAs), which, as I understand it are "static" and will hold state even if the clock stops. I've build some "busy box" boards with switches and lights to simplify breadboarding stuff like testing the VIAs (because they were causing me no end of trouble at the beginning of the RIBBBIT65 project).

[turbid hill]

@ornate ether thanks I will look into that.

[sudden slate]

Happy late Thanksgiving!

[pearl shoal]

Hi folks - hope you had a great Thanksgiving. I love the AT guide. I do have a quick CP question...

I need to activate an AT switch when a user vocalizes a particular tone. Ideally, three tones with three different outputs. Any suggestions on hardware that would work best for this? Do we have an FFT/tone detection library? I can fall back on a RPi4 + Braincraft which I'm using for other stuff for her, but I'd like a simple tone switch.

[smoky island]

Hello folks. No Deep Dive today. But I'm starting up a stream now. Hang out here in the chat and follow along on Youtube: https://www.youtube.com/watch?v=5wKQtcsRdFg or Twitch: https://www.twitch.tv/foamyguy_twitch

[lavish frost]

sounds good 👍

[pearl shoal]

Watching now @smoky island

[lavish frost]

No problem 💪 always happy to try to make things mobile friendly

[grand tusk]

Hello everyone. Today I'm driving the FunHouse.

[pearl shoal]

Feathers & Featherwings are 20% off today (until midnight)

[nova totem]

I wonder if the code used for some of the sound visualizers can be modified to detect the tone?

[pearl shoal]

@nova totem well, I have an edge badge & a rPi4 + Braincraft, and a CP Bluefruit so I think I have good hardware to test... just need a direction

[brazen grove]

good evening

[lavish frost]

at some point I may want to pick you brain on player devices... there's a project at work that might be coming down the pipeline to make a "dashboard"-esque display for the main office

[nova totem]

To use "less" hardware I do wonder if you could use the microphone on the bluefruit and try the FFT code to detect the tone. Never tried though myself. I know like the new eyeglasses had the spectrum display so I think that could detect a tone (same microcontroller as the glasses controller)

[pearl shoal]

I was thinking that maybe a guitar-tuner code could be repurposed

Yes! That FFT stuff is what I'm looking for

[nova totem]

Oh yeah I would think that would work, makes sense to me

[pearl shoal]

Can you post a link to that?

[nova totem]

https://learn.adafruit.com/adafruit-eyelights-led-glasses-and-driver/music-reactive-lights

[pearl shoal]

Yes, those are the boards I have w/Mics

Looks like @robust horizon might be a good person to partner with on this

[smoky island]

https://learn.adafruit.com/ulab-crunch-numbers-fast-with-circuitpython/fft-example-waterfall-spectrum-analyzer

[pearl shoal]

I didn't realize the glasses controller had a mic - so cool! I have one of those too

[brazen grove]

jlink stands in for openocd

so when you use jlink, you don't need openocd

you can also use black magic probe, that lets you connect gdb directly to it

without openocd

[nova totem]

I really have to take the time to learn to setup proper debugging for the core

[brazen grove]

me too

I have only used it for flashing

[nova totem]

I'm literally adding printfs to the code right now to figure out how something works 🙂

[brazen grove]

that is the way, also, blink a LED

you can read what's written on the chip

[nova totem]

I found out you can't make a native class subclass another native class. Trying to figure out why

[brazen grove]

it's not in apt

you need to download it from Segger's website

it's closed source :(

you need the same build for which you have the ELF file

debug build is going to be easier to debug, but it should work anyways

[sudden slate]

The new server image is lit

@grand tusk WDYM with the 🙉

??

[brazen grove]

the microphone was bumped

[sudden slate]

Oh

hehe

[grand tusk]

Reacting to loud noises. 😄

[sudden slate]

LOL

[grand tusk]

Which one is the target?

[brazen grove]

the metro m0 express

make sure the debugging cable is correct

it pauses the cpu when it's connected

run gdb

you can do it without the elf file

[wind spoke]

It's very Xmas if there is an Elf...

[pearl shoal]

I'm only half listening

But you can debug w/o an elf file - that's usually just the symbols to help you see the names

[brazen grove]

you can run make BOARD=... clean all to clean and build in one command

"all" is the default target for make

[wind spoke]

Accept that...

[brazen grove]

it says version 5

[wind spoke]

curses help controling the terminal, change colour, position the cursor, ...

[pearl shoal]

curses (ncurses) is an old linux/unix library for controlling the terminal

As @wind spoke and I know because we're old

[brazen grove]

install libncurses5

[wind spoke]

So I am old too...

[pearl shoal]

You might need version 5, not version 6

[wind spoke]

It say so.5 ... so 5 it is...

[pearl shoal]

Don't do that

Don't the do the ln -s thing

versions 5 & 6 probably are not compatible

[brazen grove]

just install the version 5

[pearl shoal]

install the libncurses5 package

That will be alongside the version 6

[wind spoke]

Haaaa we will have one library missing after the other!

[grand tusk]

Why Python 2.7?

[brazen grove]

it's a version of gdb with python support

install libpython2.7

[pearl shoal]

yay!

type bt

[grand tusk]

Seems like Scott mentioned Python support in gdb a few weeks ago.

[pearl shoal]

once you're connected

you are in GDB now

[brazen grove]

you need that 'external' command in gdb

[pearl shoal]

You need to give it the program to load

[brazen grove]

to tell it the port

[pearl shoal]

listen to @brazen grove

[wind spoke]

I am going to learn things... I usually debug with printf!

[brazen grove]

I guess you need the elf file after all

[pearl shoal]

You are at a breakpoint

The question marks are because you don't have the elf

try typing bt

[wind spoke]

Missing symbole, so it does not know where you are ?

[pearl shoal]

and hitting enter

[wind spoke]

back trace ?

[pearl shoal]

So, the elf file will help

yes

[brazen grove]

it's question marks, because you don't have debugging symbols

[grand tusk]

Put the elf back on the shelf.

[brazen grove]

should be fine

[wind spoke]

Try to use the elf that match the uf2... or 🙂

[brazen grove]

it might not get to the bootloader disk with the debugger connected

[pearl shoal]

exit gets you out of dbc

gdb

"exit"

[brazen grove]

q

[pearl shoal]

quit?

It's been years

[wind spoke]

It is so bizarre I seems to remember things about gdb, but I am pretty sure I never used gdb. Or was it so painfull that I hided that memory?

[pearl shoal]

In 1995 I spent 1 year debugging a COBOL interpreter on an HP/UX system with nothing but Emacs and GDB

Turns out, that's all you need to debug

GDB really is that old

[grand tusk]

COBOL is older.

[pearl shoal]

Did you put it in the background? type 'jobs'

[nova totem]

I don't think I've used GDB since university

[brazen grove]

do fg and then ctrl+c

[pearl shoal]

fg

fg will restart it

foreground

[brazen grove]

yes

[pearl shoal]

Yes

linux/unix (again, very old)

[brazen grove]

we show our ages

[pearl shoal]

I love when old brain cells are useful

[nova totem]

All that unix stuff paid off in the long run

[pearl shoal]

Youneed that target command

[brazen grove]

you need the target command again

[wind spoke]

Usually I was doing Ctrl+Z then bg for putting in background something.

[pearl shoal]

bt

[brazen grove]

continue

[pearl shoal]

continue will have the program continue

backtrace will show wher eyou are

[wind spoke]

You are stuck on a breakpoint, so you have to continue.

[brazen grove]

I think we have a freeze

[wind spoke]

What are the command for step by step progress

[pearl shoal]

also step/next will move you forward

AH

I thought he was thinking real hard

[brazen grove]

humans usually breathe

[wind spoke]

Somehow the chat still move...

[pearl shoal]

weird - the cursor is blinking

His camera died

But OBS lives!

[wind spoke]

Maybe he run gdb on OBS by mistake?

[brazen grove]

I guess jlink nuked the usb

oh

[wind spoke]

Make sense...

[brazen grove]

usb is nuked because the circuitpython is not responding to it

[wind spoke]

Unplug the board?

[pearl shoal]

That sounds right - he needs to pull the plug

or type continue

[brazen grove]

I guess you want to plug it with a no-data cable this once

[wind spoke]

Can he get the REPL on a UART?

[smoky island]

almost back

[pearl shoal]

Might need a new link

[smoky island]

New youtube link: https://www.youtube.com/watch?v=rqFm-D51UL8

[pearl shoal]

Back

So, you might need to type continue when you connect or it will hang the USB buss

bus

So, CircuitPython was stopped when GDB connected to it

That means it wouldn't be responding to USB requests

So, you want to hit continue and let it run until it crashes

then it will stop automatically

yes

it's a gdb command

right after the target command, you type continue

Yes, right after that

[brazen grove]

or just "c"

it's also possible to power the metro from the jlink, but I don't remember the command for that

[pearl shoal]

Don't worry about the ??

It means that the point where it stopped you was not in the symbol file

it's in some lower level file (libc or something)

don't worry about it

Now go to the repl and make it faile

try it

[brazen grove]

if it helps, if you create a displayio display, release it,and create it again, it crashes

[pearl shoal]

try the command

[grand tusk]

The microcontroller.nvm works on the samd21 Metro board.

[pearl shoal]

Well, while we wait anyone want to help me debug the rpi4 problem I'm having?

went through the steps on the braincraft guide

[brazen grove]

have you tried switching it off and on again... ;-)

[pearl shoal]

can't get raspistill to work (not installed it seems)

[brazen grove]

install it?

[pearl shoal]

it says it's in libraspberrypi0 and I installed that

[brazen grove]

apt-cache search raspistill to find the package

I think the latest raspbian ha problems with the camera

not supported yet or something

so maybe they removed it

[grand tusk]

I smell smoke (from the solder).

[brazen grove]

a startup idea: flavored flux

[pearl shoal]

looks like it needs python2

working on it

back to the show

I think the guide may need to be update ```

Control-c

You need the elf file from the build on the feather

I mean the pico

[brazen grove]

SWD SWC and powwer

[pearl shoal]

The three on the end

Ground is ground

[brazen grove]

ground is ground is ground

[pearl shoal]

Pick a ground pin

https://tenor.com/view/the-groun-sink-reddit-com-mincraft-fail-gif-19964752

Yes

[brazen grove]

you need vref

yes

3.3V from pico to vref

the same power as the MCU gets

no smoke

you need to specify different mcu model

clean all

[pearl shoal]

Need the name of the board

[brazen grove]

the dots are the board you want

capital BOARD

[pearl shoal]

Yes, make will take any number of targets

[brazen grove]

within reason

[grand tusk]

the RUN pin

[pearl shoal]

there is nothing reasonable about make

[brazen grove]

nonsense, it's the sanest of the bunch

[pearl shoal]

I almost threw a computer out a window figuring out an automake problem

[brazen grove]

make defenestrate

autotools is a separate thing

it's evil

[pearl shoal]

yes, but so many open source packages use it it's a requirement to know it... and it blows

I think you hold it while resetting

Looks like a starting point

[brazen grove]

the voltage looks a bit low

[pearl shoal]

Connect it to one without the D

and maybe pull the VREF line?

[brazen grove]

d like diode?

make it has a shottky diode on it, that's why there is a voltage drop?

[pearl shoal]

I thought digital?

GND is GND, but GNDd is not GND 🙂

[brazen grove]

just guessing

[pearl shoal]

Make sure you type continue

[brazen grove]

now bt

[pearl shoal]

bt

type bt

crashed in the USB stack

[brazen grove]

in the usb serial, I think

[pearl shoal]

readline is reading input from the REPL

This is a timing crash for the USB?

[brazen grove]

try monitor reset to reset it

c

lucky! :)

[pearl shoal]

Probably only when connected to the debugger

debuggers introduce timing issues

[brazen grove]

anti-heisenbug

[pearl shoal]

You're not stuck yet

[brazen grove]

yes

[pearl shoal]

Control-C will break it

(which you want)

[brazen grove]

or reset it and set a breakpoint in the fault handler

[pearl shoal]

try 'list'

[brazen grove]

the debugging guide should have an example

[pearl shoal]

break in hardware_alarm_irq_handler

yes, you are good

it doesn't know where the source is

type "break in hardware_alarm_irq_handler"

[grand tusk]

The #2 breakpoint?

[pearl shoal]

sorry no "in"

up arrow should work

monitor reset

[brazen grove]

monitor reset

and then c

[grand tusk]

💥

[brazen grove]

it broke already in the irq handler

because it's getting called all the time

[pearl shoal]

gotcha - wrong place for the breakpoint

[brazen grove]

clear it

clear 1

sorry

can't remember the command for clearing breakpoint

[pearl shoal]

help

🙂

[brazen grove]

it is clear

[pearl shoal]

help breakpoints

[brazen grove]

clear harrdware_yadda_tadda_handler

[pearl shoal]

I think it cleared it before

and gave you the file issue

[brazen grove]

delete deletes all breakpoints

[pearl shoal]

as a warning

scroll up and copy the other function

further up

[grand tusk]

do 'list' again

[pearl shoal]

_reset_handler

delete what you have

then add one in _reset_handler

[brazen grove]

I think you want to set a breakpoint in HardFault_Handler

[pearl shoal]

I am not certain you have a stack crash - I think you have a loop where it's stuck in the interrupt handler?

I think he's right - and you might have to wait while the loop hits it

monitor reset

then c

type c

it broke immediately

[brazen grove]

you did hit a breakpoint

[pearl shoal]

type bt to see your backtrace

so, delete breakpoints and then the FardFault_handler

Hard, not Fard

[brazen grove]

thank you professor Freud

[pearl shoal]

nope

[brazen grove]

I think we need DEBUG=1

[pearl shoal]

I might need to head to dinner

[brazen grove]

I got that name from https://learn.adafruit.com/debugging-the-samd21-with-gdb/micro-trace-buffer

[pearl shoal]

No problem...

[brazen grove]

-j 8

so that hard fault handler may be specific to SAMD

because it's in asf/sam0/utils/cmsis/samd21/source/gcc/startup_samd21.c:284

c

monitor reset

it's probably a usb timing problem with the debugger

that speed is just the communication speed for the protocol

because the protocol is similar to SPI

fixed ;-)

ctrl+c

can you look in that file?

[pearl shoal]

type bt

[grand tusk]

Where is the nvm? Flash?

[pearl shoal]

That's a .o file

[brazen grove]

there should be a corresponding c file somewhere

[pearl shoal]

hit enter

[brazen grove]

oops

in SRC

it's an assembly file

crt0.S

circuitpython/ports/raspberrypi/sdk/src/rp2_common/pico_standard_link/crt0.S

[pearl shoal]

you should be able to type "list" and it will read it

[brazen grove]

I don't know ARM assembly enough to understand this

[pearl shoal]

backtrace is showing the history of function calls

yes

needs debug build

right

it goes out and finds the source file

[grand tusk]

Lost the stream again?

[pearl shoal]

Your stream got ugly

So... the problem is the CP code that calls that

[brazen grove]

try continue and ctrl-c again, maybe you will land in a different place

because this is inside timer interrupt

[pearl shoal]

@brazen grove doesn't GDB support multiple threads? like 'threads'? my memory is old

[grand tusk]

There's the gong. Thanks, it's been educational! 👋

[brazen grove]

ok, so it's stuck in that loop

[pearl shoal]

heading out for real

[brazen grove]

a few lines above it it says:

// exit should not return.  If it does, hang the core.
// (fall thru into our hang _exit impl

so this is an exit handler function

I'm heading to bed too, good luck

[smoky island]

Thanks all. I learned a lot. Appreciate everyone who hung out or watched on twitch or youtube. I'll be back in the morning tomorrow. Hope everyone has a great night and great weekend!

[grand tusk]

Next time let's play "Keep Talking and Nobody Gets Hurt".

[pearl shoal]

You're still live?

Hey @robust horizon - will you let me know when you're around?

[pearl shoal]

Anyone know what MICROPHONE_CLOCK and MICROPHONE_DATA are on the EdgeBadge? Doesn't seem they're defined in the port

[smoky island]

There are some labels on the silk screen for it: I've never actually used it from circuitpython before though, so can't confirm.

[pearl shoal]

Hey, super helpful

I just switched to the CP BLE for this test but I'll need to get to the screen eventually

Any idea on this one?
'''

File "code.py", line 109, in <module>
NotImplementedError: FFT is defined for ndarrays only

[smoky island]

what's line 109 look like? Best guess from the error message, it's expecting to act on a ulab array instead of a normal list but maybe normal list was passed to it.

[pearl shoal]

https://learn.adafruit.com/ulab-crunch-numbers-fast-with-circuitpython/fft-example-waterfall-spectrum-analyzer

I copied it from there

mic.record(samples_bit, len(samples_bit))
samples = np.array(samples_bit[3:])
spectrogram1 = spectrogram(samples)

it's the spectrogram() call

Did that API change since the guide was made?

[smoky island]

The API did change since the guide was created, but I updated the guide at the time the API change got merged. It ran successfully on a CLUE for me at that time. It hasn't changed again since then to my knowledge but maybe something I am unaware of.

[pearl shoal]

I don't have a clue (no pun intended)

I do have a CPBLE and an edge badge

So I like using the CPBLE best

I took the volume level code

from the examples

and replaced the RMS with this spectrum call

Is there a way to convert the array to an nparray (efficiently?)

[smoky island]

I can give it a try tomorrow on the CLUE for baseline test to make sure the example is still working. I have an edge badge and a CPB as well so I'll give it a try adapting for those as well.

np.array(samples_bit[3:]) this should be turning it into the ndarray as far as I understand it.

[pearl shoal]

Ok, the first 3 bytes are used for something else?

[smoky island]

Based on this comment a bit above there I think the first 3 bytes are skipped essentially to "ignore" the time while the mic is starting up:

#use some extra sample to account for the mic startup
samples_bit = array.array('H', [0] * (fft_size+3))

[pearl shoal]

Ok

This seems to hang Mu when I open the serial port

I'll bang it out.

I'd like to not have to reallocate that array if that's what it's doing

[pearl shoal]

Lots of progress

[smoky island]

Next stream is starting up in just a moment. We'll be back out of the assembly weeds and playing with Displayio some. Hang out with me here in the chat and follow along on Twitch: https://www.twitch.tv/foamyguy_twitch or Youtube: https://www.youtube.com/watch?v=ieSmOD-UVO0

[grand tusk]

Hello. Stream looks good, audio good (YT).

[brazen grove]

afternoon

[clever summit]

Hey Tim! You may want to check the Youtube chat.

Yeah, they come and go.

Looks strange. Says message removed but I can still see it.

Ah. Yeah, that it's.

[grand tusk]

🎉 💥

I meant the absurdly large number before splash.

[brazen grove]

it looks like a bug

[grand tusk]

dir() lists all the globals.

[brazen grove]

possibly an interned string that is not found

[grand tusk]

That's what happens when you run pre-release code I guess.

That's after a long interactive session at the repl.

(sysname='rp3a0', nodename='rp3a0', release='7.1.0', version='7.1.0-beta.0-94-g584e88974-dirty on 2021-11-19', machine='Raspberry Pi Zero 2W with rp3a0')

fontawsome is...awesome.

[grand tusk]

What would happen if you wrapped the label in a widget, instead of adding it to the grid unwrapped?

[grand tusk]

Looks good!

[grand tusk]

One of the lines is missing (bottom right).

And it seems the stream has halted.

Is it possible to scale a bitmap? My QR codes are too small for my phone to read unless I scale the top level Group, and that creates other problems.

The bitmaps I'm using now are 29x29. I was surprised that the Group() will only scale by integers.

If I scale the top group it messes up the layout math.

Thanks, I'll give it a try.

Wrapped the QR code in a Group, scale=3. That's what I wanted!

It would be good if TileGrid had width and height properties.

Thanks, it's been fun.

Desk of Ladyada - Loooong weekend to finish the QT Py ESP32-S2! https://youtu.be/nQnyOD9b7Ag

Evening y’all!

[mellow thunder]

New QT Py...Nice!

[fair fulcrum]

=^-^=/

[slow spire]

I was wondering how double-sided it would be!

Quite dense

[ashen hound]

does this board have to be FCC certified/validated before it goes on sale? Does it matter since it is for prototyping

[green bison]

How much if any do you use the auto router?

[slow spire]

Love it. I like working with small components in prototypes

Will this support BLE in CircuitPython and/or Arduino?

[green bison]

Well I heard it from one of the best, don't use auto router

[slow spire]

Oh wait WiFi only I think.

[fair fulcrum]

yay u.FL on a adafruit board! I have really liked the partical feather boards for my longer range wifi bluetooth stuff because of their external antenna capabilites.

[lilac tusk]

No, WiFi falls in a range that isn’t licensed so hobbyists can make without the need of FCC certification

If it was used in a mass produced commercial product (I.e.: not a makers Wifi light controller) then you would get it certified

[ashen hound]

Thanks. I was always confused by FCC's requirement of "allowing only upto 5 radio prototypes"

[lilac tusk]

It’s super weird and confusing

[slow spire]

How is nRF52840 availability going forward?

[grand tusk]

Inspired by PT.

[drowsy inlet]

Question if there's time - How does this differ from the "Mini Oval Speaker - 8 Ohm 1 Watt" (https://www.adafruit.com/product/3923) ? Is it the same speaker just with the stemma connection? Thanks.

[grand tusk]

Great for playing "Street Chicken"!

And you all just lost the game.

[sudden slate]

Say what now

??

[steep dew]

Well, I feel obliged to explain, now that you have asked. The game is simple. Once you know the rules, you are always in play. The goal is to never think of the game. Whenever someone that plays the game thinks about the game, they must exclaim so to anyone around. If those people are initiated (for instance by reading these rules) they have also lost the game, and must start over.

Slammin the hot chocolate.

[sudden slate]

Hey all

[ionic garnet]

I got my Pink Feather RP2040 today

[nova totem]

already hot my quota of hot chocolate for today (not that there is a quota...)

[sudden slate]

I got my normal, not-pink Feather RP2040 today

[open surge]

The pink ones are so readable! I really like it

[ionic garnet]

I was so excited at the pink board I went running upstair to show Sue. She was like "very nice. What do you do with it?" I was like "have you been listening to me for the last 40 years?" (we started dating in 1978)

[sudden slate]

I know!! I'm sad I didn't get a pink one 😦

[open surge]

I was actually thinking of putting it in a shadow box and hanging it

[sudden slate]

I don't have 100$ to spend atm

hehe

[ionic garnet]

I bough a plain one two in the last couple of orders. I like to stage Adafruit boxes to come every few days.

[sudden slate]

I'm not that rich

[open surge]

@ionic garnet My wife would have words with me if I did that!

[upbeat coral]

I actually set an alarm that night to make sure I got my order in on time.

[ionic garnet]

I had a problem similar to that. I had just transferred some funds around and forgot about the bank holiday and money not moving. I had to find a way to use cash. Easy fix, buy a prepaid debit. By the time I did that my funds were available!

[open surge]

I was a bit surprised when I woke up in the morning and they were still available. I took that as a sign to buy the stuff I needed for my next project

[ionic garnet]

I was joking. I think I said "all the stuff with blinky lights and moving parts on our crafts"

[open surge]

🙂

[ionic garnet]

I try to never speak rudely to anyone

I wish I had learned that skill when I was younger

[waxen thistle]

We all learn and grow -- and you wouldn't be the person you are today if you didn't learn those lessons & make mistakes back then.

[ionic garnet]

True enough. I was pretty insane in my Silicon Valley days at Symantec in the 80s and 90s

but insanity was required as we were growing from $100M in sales to over a $1B in sales

not for the feint of heart

I love mistakes. When I interviewed with Cynthia Breazeal, the creator of Jibo, she had me meet with the lead VC/angel. He labeled me a "High Risk/High Reward person" and advised them to hire me. So I use that as a title to my podcast

one of my mentors told me while sitting at Warner Hollywood lot while making a movie with the band The Police that "if you aren't getting fired frequently, you aren't taking enough risk". I told him "don't worry, I got that part down."

flashing a esp I screwed it up sigh

[ionic garnet]

I fried so many WS2812bs in the last two weeks. So I know how you feel @turbid hill

luckily I just chop out the bad ones and solder the good ones

Boosted as well! 2 Pfizers and one moderna

[waxen thistle]

Embrace the damage -- 2020-2022.

[turbid hill]

I prob just screwed up the flash process

[slow spire]

Hi all!

[ionic garnet]

I bricked one Sparkfun Pico 2040 Lipo. Can't wipe or recover

No idea how

it is indeed what it is

bravo

PT, I love the leadership Adafruit displayed in dealing with this stuff

[turbid hill]

wonder if you could get into the rp2040 through the debug port

[ionic garnet]

hmm maybe. I don't use picoprobes and all that so much so didn't think of that

[turbid hill]

has to do this with a stm32

[ionic garnet]

Actually my bad, it was a Pimoroni board with similar feature set/size

[slow spire]

@ionic garnet I bet there’s a way to unbrick. Someone here will know.

[ionic garnet]

Perhaps that is my question tonight!

[slow spire]

@ionic garnet @open girder question about is there an easy way to unbrick 2040

[turbid hill]

here is a pinky feather

[ionic garnet]

Question: I have a Pimoroni Pico Lipo, an RP2040. I put CP on it around 7.0 beta. I somehow hosed it so I can't get it to turn on anymore. Any ideas how I might troubleshoot it or should I write it off?

I missed JP's show but I bought that STEMMA QT speaker/amp a few days ago and it came today

PT you probably packed my order!

[slow spire]

Ooooh easy speaker STEMMA add-on!

[ionic garnet]

I love this little STEMMA board

A real step up for Piezo

[slow spire]

What did we just dial?!

[ionic garnet]

without need for an amp too

cuz it has one (2 watts mono I believe_

really an excellent value IMO even full price

i am all for solder-free stuff. I can solder, but why if you don't need to?

[smoky island]

I'm guessing you tried already, but just in-case. Does holding boot button, then pressing reset while boot is held give you anything? While it's plugged in to a PC especially check to see if new serial ports show up. I'm not familiar with that device but some RP2040 based devices don't necessarily have the storage BOOT drive style bootloader pre-loaded on them.

[turbid hill]

Soldering is relaxing I like doing it except when I today put the connectors on the wrong side of servo feather board

[velvet beacon]

Hi folks! yay, chatting about Giving Tuesday 🙂

[slow spire]

Hi, @velvet beacon

[ionic garnet]

I will repeat this. I believe I tried everything I could find online. I have dozens of other RP2040 from Adafruit, Pimoroni and Sparkfun and never saw this. I through it in the broken toys box

[turbid hill]

that button patern is generaly a esp32 pattern to put a esp in programing mode

I would not worry about it, I have a bricked pico but since I have another 15 spare since they are so cheap

[desert orbit]

Nothing heals the soul more than helping people ❤️

[vagrant flax]

[ionic garnet]

Speaking of charity, one of most fulfilling things I've ever done was spending 5 years raising Guide Dogs for the Blind for the charity of the same name. It was my late wife's childhood dream. I did it for her but I fell in love with it. She passed away 4 years in but she was happy and satisfied. Helping others is the best therapy

I lived on west coast at the time. But the last of 3 guide dogs I got to adopt. The other two became guides.

[smoky island]

actually taking a look at the docs for that device. It looks like it doesn't have a traditional reset button. But rather push on / push off style power. So it would be hold boot and then press the power button twice (once for off, once for on)

[ionic garnet]

I will try that

[turbid hill]

one of the pins on the pico if shorted with gnd causes a reset

[slow spire]

No solder, no code, with Wippersnapper plus STEMMA

[smoky island]

1st one is always the hardest. This is awesome news. Love to see more capabilities added to wippersnapper

[ionic garnet]

I probably just swore at it and asked it why it wasn't like all the other well-behaved boards. I have a second identical unit works great

[turbid hill]

pin 30

[open girder]

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

[turbid hill]

is the run/reset pin

[ionic garnet]

i usually forget to apply the discount code. Then I remember but think "I'm happy to let Adafruit keep the money". We all support each other

[strange mantle]

@ionic garnet the RP2040 has a ROM (can't be overwritten) bootloader - and - that ROM bootloader is UF2, which should create an RPI-RP2 folder. in general, there is no way via software to mess up the bootloader. should be able to get back to it via the suggested button press dance.

[turbid hill]

when doing pico get this from adafruit https://www.adafruit.com/product/4901

[ionic garnet]

the problem was I saw no signs of life. Not sure if I peeked at the USB device. I know I can recover the other one to boot into RP1-RP2 to recover from a failed push of code

[hot frigate]

Yay Cooperative multitasking!!!!

[slow spire]

Cooperative multitasking reminds me of my time coding for Mac OS system 6 - 9

[turbid hill]

Lol now need uncooperative multitasking

[ionic garnet]

I was using a '19 i9 MBP, which recently was added to the broken toy box. Now I'm using MBA 11" M1 and having lots of problems with USB through a dongle. If a device draws too much power, MacOS boots it off USB bus. Unrelated to the 2040 board problem,

Uncooperative M/T and user hostile interfaces FTW

[turbid hill]

weird have prepped a m1 mac at work and had no usb issues

[ionic garnet]

thanks for all the suggestions. I think it might be the dongle.

[robust horizon]

concurrency is hard. someone tried to make a game out of concurrency bugs: https://www.metafilter.com/193440/Deadlock-Empire-Single-link-Web-puzzle-game

[ionic garnet]

I have 3 or 4 USB-C to USB-A/HDMI/ethernet dongles. I should try using a different one. These are not cheapies either. I typically buy high end stuff

Adafruit Pain Box ™️

[ionic garnet]

It annoys me my M1 MacBook air can only drive one external monitor. I like to use 2 32" UHD monitors. Otherwise love the M1 machine.

We loves cool stuff

[turbid hill]

at work I got a usb-c dock from aniker from amazon and it drives two monitors plus the macs own screen

[ionic garnet]

get it: sand... Dune

[velvet beacon]

all the blinkas!

[ionic garnet]

On MBP I can do that. Not on the 2020 Air M1

[desert orbit]

I still have nightmares about a java app i inherited at a past job that fired up new lots of new threads to handle important things. And those threads could never die or except or the whole thing would fall apart. 😅

I’m excited about async/await!

[ionic garnet]

only supports one. You can mirror more than one.

[turbid hill]

Looks like the workers are all buzzed on coffee overload

[slow spire]

Has a MBA ever been able to drive 2x 32”?

[turbid hill]

The M1 I did at work is supporting two via the dock

[desert orbit]

I love watching the selective solder machine work. So strangely relaxing.

[ionic garnet]

Time for a new Mac anyway. Still really upset about the Big Sir update bricked my MBP. I followed the fix instructions only for it to fail in new ways. Apple can fix no doubt.

[waxen thistle]

@slow spire I think it depends on the resolution. And I think the M1 would have the best luck.

[ionic garnet]

Cool. Maybe the limitation is all in my mind!

[velvet beacon]

@desert orbit I was thinking the same thing

[slow spire]

Probably going to get a 16” MBP max myself

[turbid hill]

yes I am only using 1080p at work but my CFO wants a big wide screen instead

[ionic garnet]

https://www.macworld.co.uk/how-to/how-connect-two-or-more-external-displays-apple-silicon-m1-mac-3799794/

[open girder]

on a 16" mbp here, it's great

[ionic garnet]

Nice

[waxen thistle]

that new MBP m1 max is very inticing

[open girder]

it keeps up with me 🙂

[waxen thistle]

I'm on a late-2019 16" MBP here, and it's pretty solid too

[turbid hill]

my CFo has the new M! but not the max version, one model down

[ionic garnet]

I have so many Macs but only one M1. I have been all Mac all the time since about the Intel switch. Had Macs from 1984 onwards but they were toys.

[slow spire]

My first Mac had the $1000 640x480 monitor.

[waxen thistle]

[the m1 is no doubt better, but what I got worked great when i first needed it]

[ionic garnet]

My first one had the built in monochrome with only a floppy disk and 128k of ram. I used an article from Byte to upgrade it to 512k!

[smoky island]

Once that building is complete I kind of want to see all of the timelapses from each week cut together.

[ionic garnet]

A very expensive toy

I still have a gooseneck iMac I bought for my daughter

it still works

gooseneck

People often wonder why I switched to Macs approximately one year after having the source code to Windows in one of my jobs. NDA prevents me from saying!

[odd fox]

Love the Menorah. I would LOVE to get a rabbi's opinion on this as a replacement for some dangerous candles.

me too. Wish I had built one BEFORE the holiday!

[odd fox]

Sadly, evert year there seems to be sooo many people who burned their house down due to the candles.

[robust horizon]

Also from the same article:

Following the Menorah lighting ceremony, participants will be treated to hot drinks and donuts and the all new 3D Dreidel Glasses (which make all street lights look like a dreidel when you are wearing them), and a show by the Hoop Wizard.

[vagrant flax]

Ominous 😮

[ionic garnet]

I have a strand of just a few neopixel fairly lights that survived a mishap. Plan on making a menorah with them is some kind of arty menorah shape. I bought some cool Menorahs in Amsterdam decades ago for inspiration.

[velvet beacon]

@desert orbit we'll be sure to let the team know!

[ionic garnet]

I spent one summer at age 16 in Ft Lauderdale Pompano Beach area. Not for me. Move 4 years later to California

[open girder]

everyone give it up for the best CFO in the biz ... @velvet beacon !!!

[ionic garnet]

STELLA

[velvet beacon]

@robust horizon @open girder same here! fun show as always ❤️

[desert orbit]

Tbh Adafruit is basically the only place I don’t have to check inventory for. But I still do, because awesome quotes.

[ionic garnet]

but as a recovering ex-Jew, I am obligated to retire there

so no plans to retire

[velvet beacon]

awww thanks, folks!

[ionic garnet]

You are part of a great company! We all appreciate you as loyal customers

CFO = one of the C-level jobs I've never held!

[velvet beacon]

❤️ we do have some great quotes

[cinder wind]

dang missed it! hi everyone! bye everyone!

[ionic garnet]

It was amazing. They gave away free money and in prime Oprah style gave us each a new car with a Pink Feather RP2040 in the onboard computer.

[cinder wind]

ah darn. oh well, maybe next week

[ionic garnet]

since they frown on cars, these were matchbox cars. But it was still exciting. How are they going to top that next week? Maybe a Lego-hot wheels?

anyone know where Doctor has been? I miss him

[sudden slate]

hehe

[sudden slate]

Me too

@teal river - are you still active??

[vivid ore]

He's been busy with his new job IIRC. I have seen him pop in from time to time, but it has been a while.

[sudden slate]

Cool

[lavish patrol]

Greetings.

Aloha!

[haughty quiver]

Hi Steve!

[viral sail]

Good afternoon.

[grand tusk]

Hey there!

[lavish patrol]

[viscid bolt]

Good afternoon

[grand tusk]

YT has bleeps and bloops!

[lavish patrol]

Lars has a new hat.

[grand tusk]

Saw you last night on the show-n-tell puppet show.

[ivory flax]

Hey John

[drowsy inlet]

the table looks so clean

[lavish patrol]

Lars - now available in a handy six-pack.

[smoky island]

The world is not ready for 6 of Lars.

[lavish patrol]

Lol.

[lilac tusk]

Ya know, funny enough my dad had a friend named Lars

He had a music recording studio

[lavish patrol]

That's Lars in a previous existence...

[drowsy inlet]

need to try the solo cup suggestion

[lavish patrol]

What's with all the flourescent lamps?

[inner spade]

Interested in finding uses for the new aluminum Solo.

[lavish patrol]

Neat trick.

[grand tusk]

That's a great tip!

[viral sail]

Could you use \t to tab them into columns?

[lavish patrol]

Does that work in all pythons?

[drowsy inlet]

yes and yes

[grand tusk]

python3

[lavish patrol]

👍

[drowsy inlet]

using tabs to get tabular data you might still want a newline tho

also, text length could bump you to the next column if too long

might consider fixed sized output fields

[lavish patrol]

So if you leave it out, "end='\n'" is implied.

[grand tusk]

if count % 10 == 0: print()

[spiral vale]

getting analog data --- like from a neo-slider?

[grand tusk]

How did you know?

[inner spade]

You can also include variables in the end= portion: ```python
print(i, end=str(another_value) + ', ')

[lavish patrol]

Cool.

What happens if you put print('', end=str(another_value) + ', ') ?

Yep. still works.

[inner spade]

>>> another_value = 89
>>> print('', end=str(another_value) + ', ')
89, >>> ```

[grand tusk]

You have to add solder to change the neo-key address.

[lavish patrol]

Chevron 7 locked.

[formal ferry]

I would love to see a slider key cap with a lightpipe

[fresh flame]

It's just crazy how much can you do with a single stemma qt

Oh just realised that there's a sparkfun part

lol

so it's technically qwiic 😉

[formal ferry]

I am getting addicted to i2c devices, I think I have a dozen different boards now for "future projects". I have a mix of SparkFun, Adafruit, and a few generics off eBay. (I just wish they would all stop using different branded names for the same thing)

[fresh flame]

same

I hope grove gangs can have a mini-grove

so they are interchangeable with Stemma QTs

[grand tusk]

vcvrack can be temperamental.

[fresh flame]

vcvrack

such a good open source project

destroyed by it's closed source paid advanced features

(this chat is not on the video? phew...)

[lavish patrol]

Lol.

[spiral vale]

BespokeSynth is another cool project (which is fully open-source/open-contribution)

[fresh flame]

yes BespokeSynth is way better

It have a puredata vibe to it

[spiral vale]

different, but interesting visual patching approach

Runs on RasPi too!

[grand tusk]

Nice, but can it play Street Chicken? 😁

[spiral vale]

likely

[grand tusk]

Time for a modern interpretation of the VESTAX Faderboard.

[spiral vale]

RGB version of this https://github.com/16n-faderbank/16n

HOw many addresses available on the neosliders?

🥁

[grand tusk]

2**4=16

[spiral vale]

4

at least 6

[grand tusk]

Lars lost his hat. ??

[lavish patrol]

He's asleep.

[spiral vale]

maths is hard

[drowsy inlet]

is the slider basically a linear version of a rotating potentiometer?

awesome thank you

[inner spade]

2^4 = 16

... and from @grand tusk

[viral sail]

Thanks @haughty quiver

[grand tusk]

Hope you're feeling better soon. This was a lot of fun!

[lavish patrol]

Thanks, @haughty quiver 👍

[inner spade]

Excellent workshop today, @haughty quiver. Enjoyed the fusion of hardware, software, sound, and rack-based wiring. Get well soon!

[drowsy inlet]

cool stuff as always. thank you!

Can you give an update on the broadcom port? @rapid hornet

[green bison]

Dang I'm gonna miss the stream even though it's my day off. Have fun everyone :)

[strong acorn]

loud & clear on YT

[simple fractal]

yep, all clear

the bits are flowing

busy day here. skied for a few hours, then the gym, then shop for food.

[nova totem]

bits are good

[simple fractal]

My new computer bits are somewhere in the supply chain

Hi!

[simple fractal]

thats the part that is stuck somewhere. my mobo is lost

sleep issues are a pain. even windows has had issues. (lol, 'even')

[eager matrix]

Hi Scott. I’m walking home from he bud stop so I’ll be more able to pay attention in about 10 minutes

[simple fractal]

i had a series of no sleep or no wake running an insider build.

bud stop? thats a BC thing

the only note i found about sleep resume is not too helpful

Hello Canada from Canada

[simple fractal]

i eventually turned off some of the sleep states in the bios. i randomly ended up with something that worked

[rapid hornet]

https://blog.adafruit.com/2021/02/16/circuitpython2021-round-up/

[wind spoke]

Hello, I have a question that maybe you can touch: I found an RP2040 with only 1MB of Flash, so too small for your decision to reserve the first MB for the firmware. Would it be possible to have that has a parameter for board?

[simple fractal]

i'm seeing a lot of complaints about start from sleep, on windows. So probably a bios issue

on that mobvo

mobo

[wind spoke]

It is hardwired for the moment.

[grand tusk]

My broadcom wishlist: ctrl-c handling, async, ulib.

[wind spoke]

I'll try...

[simple fractal]

there thread on the asus forum sitll has users on the latest bios with issues

[grand tusk]

It's been great seeing what the pi zero 2w can do!

[simple fractal]

i noticed (after my git submodule update --init didn't work) that there is make fetch-submodules now. Which did work

[prime abyss]

ive been trying to get WPE running on the pi zero 2w and that has been almost impossible to figure out 😛

[simple fractal]

good, i need a non-technical bit of time. 🙂

[prime abyss]

webkit for embedded

[wind spoke]

Are you working on github only, or do you run with multiple git server in parallel for redundancy purpose?

[simple fractal]

its always been somewhat of a mystery when my CPY clone breaks.

[prime abyss]

oh man... if git went away without notice... i think the world would implode

[smoky island]

Yep. and agree'd I think it would be a really nice guide to have. Show folks how to add print statements into what they are looking at to tell how far something is getting before crashing and output variable states from the core.

[eager matrix]

Im excited that Lady Ada showed Blue Wireless products at Digikey yesterday (eye on NPI). Hopefully we'll see them on Adafruit's site soon.

[smoky island]

Thanks for showing this. It's a fascinating window to the past. I've never seen this page before. Amazing how far along it has come!

[grand tusk]

Eyeglass projects go way back.

[nova totem]

These guides were invaluable for me to get into all of this. And I still refer to them all the time for examples of how to do things

[prime abyss]

whenever i use brew on my work laptop i dont use cask

[simple fractal]

i thought cask was for installing gui apps

[prime abyss]

now i need to know

"Homebrew Cask extends Homebrew and brings its elegance, simplicity, and speed to the installation and management of GUI macOS applications such as Atom and Google Chrome."

[smoky island]

I wonder which part they are talking about, or which device. IIRC the cable has an extra slot on one side that does prevent it from going in backwards.

Ahhhh, on the jlink side. That makes sense.

I have one and can get a photo of it this weekend.

I have access already I think.

[prime abyss]

[timid plover]

is "bare metal" not meaningful ?

compared to "no linux"

CircuitPythonOS

[timid plover]

windows also runs on the pi

[sudden slate]

Hey Scott!!

How's your Friday

[timid plover]

I did like the "CircuitPythonOS" name - but agree - come back to the name later ! 🙂

[sudden slate]

CircOS

[inner spade]

A huge benefit is the added system capacity and performance for larger and more demanding CircuitPython projects.

[timid plover]

hopefully the search engines can find words in the learn guides, right? ( then we have the bare metal search keywords )

[fresh flame]

first time seeing behind the scene of adafruit learn!

thank you adafruit crews for creating all of these amazing tutorials!

[prime abyss]

learn looks like it needs a fullscreen mode for the editor

[inner spade]

Looking forward to resuming sloppy memory management coding techniques again. 😉

I am on ubuntu based system instead of arch. So not sure if it's available beyond that. But I have a screenshot utility called Flameshot that lets you grab a portion of the screen and overlay arrows, boxes, text and other things to it. You can copy to clipboard or save to file from it.
