I've experienced that.
When I was in 3rd grade, I plugged a 3VDC incandescent light bulb into a 110V outlet during science class. I learned a lot about inrush current and thermal runaway and how circuit breakers operate, half the school lost power for 20 minutes, and my teacher was picking shards of broken glass out of the ceiling for several days.

Awesome; forgive me for assuming you were just getting started.

wiznet ntp example just b/c the wiznet NTP feature was deprecated (in favor of adafruit_ntp)

☕ Morning all, just popping in before I have to head out. Hope everyone's day is starting off well!
inner spade
That looked like a typical matrix portal power brownout crash
That’s why I usually set the bit depth high and avoid saturated colors, particularly white.
(and why the palette_fader library was created)
With the S3’s memory capacity, it may be time to revisit a built-in brightness control in matrixportal.matrix.

The group boundary box will indeed be useful. Wondering if tile grids are in a list in the C code.
The display object type should already be considered in the C code, as well.

this is the newer prop-maker too based on the rp2040.

We looked at this already. It doesn't do repeated times.
dry shore
yeah, thats why i mentioned, the bot would have to be re-configured every time the date passes
so you would need a bot to re-configure the dyno bot
or a custom bot

I think most people are unaware the commands to list the times are in the channel pinned message.
and the pinned message is different in every channel, not per entire discord chat.

I knew you would like that.
I need people like you, Liz or Todbot to figure out how to produce drums sound (wave? synthio?) or do midi (there is a midi plug already, old style DIN). But I am already happy for tonight. (and that is a 17€ acquisition, including two Wii Guitars in the same price). 🙂
rapid hornet
didn't mark gamblor do drum sounds?
haughty quiver
yes, @nova totem has some synthio drum code
or if you want to do drum sample playback you can check for these: https://learn.adafruit.com/spinning-disc-step-sequencer/disc-step-sequencer-audio-and-code
sand lotus
Drum sounds can be samples and there's a ton of drum samples on the internet including classic 808, Korg, Akai, etc...
exactly
Since it's electronic you could also swap them out for midi notes and have your drum act as a keyboard. A lot of possibilities.

@haughty quiver you could cap the number of simultaneous sounds and if the user has more switches than that turned on, pick randomly among them
tulip canyon
Thanks everyone, great projects. Thanks Melissa for hosting
sage aspen
Thanks everyone for showing off your projects.
robust horizon
when I did a similar project (it never got turned into a guide and I dunno where the source is) I had one looping ambient sound (e.g., woodlands) + 8 random sounds (e.g., a bird call), and I'd play maybe just 2 or 3 of them at a time. this was on a trellis m4 I think.
so you still get a lot of variety based on your switch choices but never everything all at once

Thank you.
It seems that I don't even have the right English (or French) vocabulary to talk about drums (or sound/music/rythm). Nothing at school or in IT professional live did prepare me for this... right now I use google image on "Snare", "HighHat", "KickDrum"!!!
But ok, those are class that use synthio and numpy to create the sound to expect from that kind of instrument.
I need to start with some more simple synthio code and level up. But this is great, no doubt about it. I might start more simple, and now it is clear why my demo was RGB. 🙂
There is such a learning curve here, in an unknown territory. But I keep being facinated by what JP show, midi project by Liz or TodBot things.
It wil take time before I'll use that, but I will get there for sure.

So I have a Wii Drum machine and CP support to read the "hit" (and I could maybe also fetch a "velocity" information).
There are so many things that can be done:
- Bypass the I2C and get the midi notes from the din (maybe with CP board that receive midi notes)
- Get a CP board to read in I2C and produce midi on the USB side, then get a synth on PC to produce the sound
- Playing sound directly on the board (just playing wav or something like that)
- Maybe the ultimate level is to generate the sound on the CP board with your code or similar
So I might try easy steps first... (but anything with midi will be new to me too, it's fine, I wanted to learn).

@shell mason That was a quote from "2001: A Space Odyssey"
shell mason
funny that its sampling as i watchedblade runner
inner spade
I think you can double-check the bus frequency by print(spi.frequency)
cinder wind
sdcardio.SDCard() takes an argument for SPI speed. (e.g. sdcard = sdcardio.SDCard(spi, cs_pin, baudrate=30_000_000)
spi.frequency will tell you actual speed (be sure to do it after creating sdcard)
austere pollen
30 MHz SPI SD-Card? 😝 pah
```ino
SDFSConfig sdconf;
sdconf.setCSPin(17);

That's just kinda a joke that I did in arduino yesterday or so. But the fun takeaway from that is, that apparently my SD card can just handle the fastest SPI that the RP2040 can do 😄
lavish patrol
Printing it somewhere else?
strong acorn
to verify the speed of a particular device on the SPI bus, the code needs to be in the device's context while it has the bus
(not all devices expose that)
tulip canyon
Can you just print(spi)
inner spade
Why is print in italics in the editor?
unreal bay
on the money, 1mhz plz
austere pollen
for me it worked at over 60 000 000 😝
(but I used RP2040 with arduino. And a Sandisk Extreme Pro SD-card)
I was very surprised that it worked so fast for me 😄
unreal bay
need to adjust the busio.spi frequency via configure inside the try_lock
https://docs.circuitpython.org/en/latest/shared-bindings/busio/index.html#busio.SPI.configure
cinder wind
By setting baudrate in sdcard.SDCardio(), I am seeing the max SPI frequency of 31250000 on RP2040
unreal bay
Top bit looks right, so can they both be set to 60? and does it reflect it
inner spade
spi.frequency is a read-only attribute
unreal bay
sadly sounds same
inner spade
Set by configure(baudrate=xxx)
tulip canyon
Try printing just the SPI object
cinder wind
sdcard.SDCard() will set the SPI frequency to 8_000_000 if it's not specified, making your spi.configure() moot
you must put your print(spi.frequency) after your sdcard.SDCard() call
This is what I do:
sd_spi = busio.SPI(clock=sd_sck, MOSI=sd_mosi, MISO=sd_miso)
print("spi:", sd_spi.frequency) # prints 200000 on RP2040
sdcard = sdcardio.SDCard(sd_spi, sd_cs, baudrate=32_000_000)
vfs = storage.VfsFat(sdcard)
storage.mount(vfs, "/sd")
print("spi:", sd_spi.frequency) # prints 31250000 on RP2040
I recommend to add bad apple because everything needs to be able to play bad apple 😝

and a big hug and congrats to Neradoc for adding esp32-s3 box commits. first time i ever heard of the esp32-s3 box was on deep dive with scott like 2 years ago..
dry shore
its undocumented, but the rpi also has an SMI interface for displays with ram
in SMI mode, it will present 8-18bits on a parallel bus, and hit a strobe pin, to write a frame out one pixel at a time, into the display ram
SMI has both 8080 and 68k modes, the difference is r/w+strobe or read-stobe+write-strobe

it's best to watch adafruit streams on youtube or twitch, they have the most reliable players.
I think someone was asking a question about usb host last night in cp help channel. My thought was something like a feather rp2040 would require hard wiring a 2nd USB port on it? Doesn't it need 2 usb ports? one for input one for output? or is that just an easier way to do it?
wind spoke
I had the idea of a keyboard+screen CP device that you use as a "terminal" to work on a CP usb device that you want to configure. Exactly what you tentatively tried to show in show and tell.
Basically a remplacement for PC, maybe for kids that would work in school.
dry shore
if CP isnt connecting to another computer, then you dont need that 2nd port
unreal bay
hub/composite support? i.e. if the usb storage presents as more than simple single device?
sand lotus
I think that's something scott and jepler are actively working on... think it started with jeplers run cpm? which is a neat idea.
plus the file system walking floppy project anne did and halfway to a stand alone os.
wind spoke
Are you going to crash your computer LIVE by doing USB things? How frequently did it hapend while doing development?
dry shore
oh, i need to return back to my crazy usb gadget project, i can make a pi-zero claim to be a 20PB usb drive
lets see circuitpython crash with that!
a pico, usb-otg adapter, and a dongle for wireless keyb/mouse
if you add something for display, then this could run CP and act like a PC
sand lotus
that's neat
well you can add a TFT display to most cp boards. just a matter of an in depth gui.
and cursor support which is something they're working on. i have a suspicion that's what featherpoint was eluded to by PT on AAE on wednesday.
wind spoke
So that is the USB Keyboard workflow?
sand lotus
i used to be extremely intimidated by bytestreams. after working on a couple projects that required bytes in hex it's far less intimidating now. as a beginner hex streams are a foreign language within a foreign language.
wind spoke
If you power with a Lipo, then you can connect the Feather RP2040 USB Host to itself...
but what would be the point? Self-test?
dry shore
looks like the host tried to query the device descriptor
and didnt get an answer
get device descriptor, first 8 bytes
sand lotus
i used to get that a lot in windows with some devices. in device manager will show an error with "No USB Device Descriptor"
dry shore
typedef struct TU_ATTR_PACKED{
union {
struct TU_ATTR_PACKED {
uint8_t recipient : 5; ///< Recipient type tusb_request_recipient_t.

};
uint8_t bRequest;
uint16_t wValue;
uint16_t wIndex;
uint16_t wLength;
} tusb_control_request_t;
the setup packet can be decoded as this
which software/hardware are you using for that capture?
ah, i see the product page, ouch, $1295!
sand lotus
just searched in discord for why i was getting the device descriptor failed and ended up being the magnetic cables. one or more of the pins wasn't working right, switched usb cable and it worked fine after that.
dry shore
i think thats the ack phase of the control-in, and the NAK is the device rejecting it
timid plover
finally found the orbtrace link
https://orbcode.org/orbtrace-mini/ - is this what you were referring to?
dry shore
that feels like an issue with the usb device
also, try plugging that device into a linux host
and see what the beagle says then
sand lotus
if you aren't frustrated with code you're not learning anything new. honestly the goal is always be frustrated, always keep learning.
cinder wind
tiny grove
The people who do best at it are the ones who don't let the frustration win.
dry shore
hmmm, i see a 5 in the setup before that...
5 is set-address
6 is get-descriptor
the usb spec says the device should be able to enumerate again when it gets a usb reset
it sounds like tinyusb is upset, because it didnt fully reset itself upon usb reset
that in for set-addr seems to have worked
but i dont see the 0-byte out
switch usb host, to linux, and see how enumeration differs
my keyboard happens to have a FS only hub, which limits things
can be handy to keep some junk hubs for that
https://beyondlogic.org/usbnutshell/usb4.shtml#Control
this shows the possible packet sequences as a tree
i'm thinking add logging to the host side, what transfers and bytes your attempting to send
then confirm in beagle480, if its sending them properly
then confirm in the device, if its receiving them properly
control-in is 3 stages
setup stage, has a SETUP token, DATA0 token, some bytes, and an ACK
data stage has IN token, DATAx from the device, and ACK from the host
ack phase is a OUT and a 0-byte DATA0, and ACK back from the device
are you seeing all 3 phases in the beagle480?
but that looks to be after the device had a panic
give the device a reset, and see what the 480 says
host might also need a reset too
does the 480 show 1 or 2 gets?
yeah
the host sent 2 SETUP's, and the device got upset from that
sand lotus
In Mu commenting multiple lines is ctrl+k, just learned something new
dry shore
what is causing it to be red
the ACK packet means the device got the SETUP
it may only be red, because you did the setup phase twice
what does hcd_setup_send() look like?
does the host side say hcd_setup_send() was ran twice?
is it tinyusb intending to send the SETUP twice, or the PIO malfunctioning and sending it twice?
sand lotus
sleep. i've solved a lot of problems with a good night sleep. refresh_brain()
dry shore
setup is 8 bytes, so printing it as %08x %08x and a bit of casting would get it all, but wrong byte order
yeah
oh, color can also help with reading logs
#define CSI "\x1b["
#define RED CSI"31m"
#define GREEN CSI"32m"
#define DEFAULT CSI"39m"
bool hcd_setup_send(uint8_t rhport, uint8_t dev_addr, uint8_t const setup_packet[8]) {
logf(RED"\tHOST%d SETUP %d.%02x 0x%x/%d opep:0x%x\n"DEFAULT, channel, dev_addr, 0, (uint32_t)setup_packet, 8, (uint32_t)opep);
set the device to just hard-reboot on assert or panic?
sand lotus
and emoji's if there's emoji support. i've really enjoyed the new emoji support.
dry shore
when you call hcd_event_xfer_complete
are you claiming the setup failed?
if you mistakenly claim setup failed, tinyusb may retry
but the 480 says it didnt fail
lyric sphinx
My me doesn't have emoji support.
sand lotus
*** 🔥 PANIC *** would get your attention
dry shore
yeah, the LS max packet size is 8
so it has to do the full get-dev-desc, with an 8 byte size, setup/data/ack
within that, is the real max-packet-size, so you can then get it properly
16.220803 [DWC2:hcd_setup_send:370]: HOST0 SETUP 0.00 0xc4013f90/8 opep:0xc4113100

16.481718 [DWC2:hcd_edpt_xfer:398]: HOST0 -> 0.00 0x0/0 opep:0xc4113100 type:0

I'm still using Mu which has emoji support. I don't dive this deep.
Might start using 🪳 for exception handler errors.
dry shore
in your handle_endpoint_irq() function
can you log every argument to hcd_event_xfer_complete()?
ah, banned flash, and your uart print is in flash
wind spoke
So by default you will catch the keyboard for the REPL.
But can we have the keyboard for reading from the code, maybe to add macro and do keyboard in / keyboard out?
dry shore
what calls pio_usb_host_irq_handler(), i cant find it in the src
control-in uses OUT for the setup, IN for the reply, then OUT again for the ack
oh, it may be unpushed things
i cant find host_frame on my tinyusb
sand lotus
seems like pio enumeration isn't resetting properly?
wind spoke
Where does the intellikey developpement (the part that upload the firmware) fit in what you are doing? Is it also CP? Is it separate development?
dry shore
tinyusb has its own non-submodule copy
that seems incomplete
i think usb_setup_transaction() looks to do the setup, data0, then wait for ack
and if it doesnt get that ack, it claims PIO_USB_INTS_ENDPOINT_ERROR_BITS
exactly
the 480 should give timestamps, and then see what the pio code said
yep, thats what i was going to say to do next
usb_definitions.h: USB_SYNC = 0x80,
usb_definitions.h: USB_PID_ACK = 0xd2,
the source says its expecting 0x80 and 0xd2
sand lotus
thank you for the stream, i learned that i want nothing to do with low level programming. give me displayio and GUI design any day. this stuff is frying my brain. 🙂
dry shore
so, the problem is when your receiving the sync for the ack
the 480 isnt showing it, but every token starts with a sync symbol
if the 480 says the ack is valid, then the sync was there
and its an issue with PIO decoding that sync
sand lotus
makes me appreciate all the really deep stuff you devs have to go through. thank you.

I imagine the backporting stuff for s3 matrix portal added slightly more workload this week.

Not seen that use of pass. And overload decorator.
Always learning ☺️
sand lotus
same, what is overload?
unreal bay
Another call to same named method, but with different arguments in this case. Overload normally is used by an inheriting class to overload a function in the base class
Looks like a good use for typings
sand lotus
same, i don't vouch for any of my code too. use at your own risk. it might work, it might spit out bananas.
that's a star trek lower decks reference where the broken food replicator continually makes only bananas.
clever summit
That is a correct assumption.
That pattern is named "early exit" and is something I adhere to.
sand lotus
looks a little offset?
clever summit
The corresponding anti-pattern is "nested if's". Avoid at all cost.
noble grove
the upper left corner isn't offset. I think it's because of the alternate path
clever summit
I have been submitting code to projects that are very strict on code style.
sand lotus
that would be cool, would you still have to run black manually on a new file before commit though?
noble grove
looks a little offset?
After looking at it for a while, it looks like the gap in the middle of each line is a little less than 1/3. Could be some rounding error.
sand lotus
pre-commit and black do not play nice with github desktop windows app. i have to run black on any file change i submit to adafruit main anywhere. it's tedious.
it's beginner friendly but eventually found out it has limited capabilities vs using git CLI.
perhaps worth noting that if you have a pyportal or any device using an airlift with NINA you must now update NINA to 1.75 if intending on running WipperSnapper on it due to the AdafruitIO cert change on July 20th, 2023.

yeah noise gate a little aggressive than normal
can see your lips moving sometimes but no audio, probably noise gate.
audio is a bit louder, seems like mic boost
noble grove
yeah noise gate a little aggressive than normal
Oh yeah, I was thinking a bad cable, but no crackling so noise gate makes sense.
sand lotus
which is fine because i had to have volume at 100% to hear you
now at 75% much better and more normal
hashlib is for sha encoding
has a lot of different types of SHA all the way down to SHA-1
it's for http server security, makes sense since it's not using HTTPS
my guess is it's part of a tokenizer style of client/server response handshake. it's not HTTPS but a good thing to have for an HTTP server.
guid looks like a hardcoded salt of some kind
there's no way a hardcoded guid like that would part of a security protocol, that makes no sense. lol.
that is... not smart vs a randomized salt and sha and base64 encoding.
like a packet header.
that is so weird
inner spade
The original developer of that unique string giggles a little each time the relevancy question is asked.
sand lotus
if there's no randomized portion of the concatenation then it could still easily be used as a MITM to pretend to be the server you want to connect to.
sha-256 and base64 url encode + a set GUID could easily be replicated.
light stump
Hey all y’all cool people. Listening in a little bit this morning.
sand lotus
there has to be a randomized part to that equation otherwise the entire string will be easily cracked.
ok that makes me feel better
inner spade
It’s just a protocol exchange handshake.
sand lotus
yeah it's just an http encoding system at the end of the day.
some boards could do SSL if they wanted. an M0 would likely fall flat on its face with a 1024-bit or higher cert but an ESP32-S3 could probably handle it. would be slow but possible.
inner spade
Probably the original developer’s Windows 3.11 product key.
sand lotus
actually the airlift to adafruitIO with wipper snapper has a cert embedded in the build, so an M4 can do it.
clever summit
Server sent events is returning a stream with the content typ text/event-stream. You then send data: ... as needed.
"Javascript Python" sounds really scary. 🙂
sand lotus
Adafruit just released a new learn guide called DeviceScript that's supposed to be javascript developer friendly for Circuit Python... or something like that, haven't read it yet.
ah looks like it's for AdafruitIO not circuit python specifically.
clever summit
TypeScript is just a typed version of JavaScript. Espriduino predates TypeScript.
sand lotus
looked like an edublock/makecode element to it.
clever summit
DeviceScript is basically a replacement for CiruitPython.
I do own one Espruino device. Gave up due to lack of sensor support.
sand lotus
makecode is like that. i had fun playing with makecode for a while. and it's got a JS tab you can switch to also.
same, when it comes to sensor support there's nothing better than straight up circuit python or arduino. the libraries are really what extends the language into an entire ecosystem.
clever summit
Well, it does not really make them understand microcontrollers? 🙂
sand lotus
a bridge is a good way to describe it... or a free sample to get you hooked like a dr*g dealer. 😛 once i started learning circuit python didn't want to play with anything else, completely ignored my PHP roots too and just doing microcontroller stuff now. the world of blinking lights and sound is too cool.
web work is all virtual reality in a way. microcontrollers are just reality, with physical devices, things you can touch and feel is more gratifying vs creating things that only exist on a computer screen.
holy cow webgl has come a long way

I think i once incorrectly used it in the "gifted" sense as just a contributor. Other times I had more forethought and chose another attribution.
sand lotus
when i started I was just copy pasting the header that had kattni's name in a lot of stuff because i had no idea what to do for the copyright header.
like i thought a contribution would fail if someone's specific name wasn't in a database of copyright headers somewhere. yeah it doesn't work like that at all you just put your name in there.
and so i started putting my name in there but it still had the "for adafruit industries" and dan was like no no no, that's for paid for code only. it takes a while to learn all the nuances of the way things are done.
inner spade

Adafruit is so wonderful about attribution that when they agreed to accept a no-attribution-needed gift of one of my device drivers to support a new wing, they painstakingly included it anyway.
Thanks for the stream! Very thought provoking.
sand lotus
yeah they're pretty great all around, i do put in contributors names that help write a lot of stuff that i get stuck on and provide examples. like neradoc's name is attributed in a lot of my headers.

Side note, and @prime sentinel will probably back me up on this: none of the x86 SIMD extensions are particularly good. They are adapted from other architectures and weren't always particularly well thought out.

@tiny grove i just had an idea, based on the timezone thing in your profile
if we use the time, not "in 2h" format, like you did
then all of the times dyno reports here, will remain accurate when the date passes, as long as the user doesnt look at the tooltip
then it doesnt have to be reprogrammed every week

Displays are so much fun
dry shore
something ive been wanting to get into, was driving the rpi DSI baremetal, without start.elf
i have been able to do DPI and VEC baremetal
sand lotus
Was reading up on dsi/csi and looks like there might be licensing involved with using that spec or at least getting it officially verified and noticed raspberry pi is in the wiki for using that scheme.
Far as I could tell is dsi is like parallel with 4 pin simultaneous bits.
lilac tusk
1280x720?
sand lotus
and the data rate was something like 4gbits a sec. I was like yeah that's way more capable than a microcontroller could likely blit?
dry shore
Far as I could tell is dsi is like parallel with 4 pin simultaneous bits.
CSI and DSI are both 500mhz DDR
the rpi exposes 2-lane CSI and 2-lane DSI
so thats 2*2*500 mbit
but they then use different protocols at the bit/byte layer, and arent compatible
the CM1/CM3/CM4 expose 2lane and 4lane, for each of csi and dsi
wraith thunder
and the data rate was something like 4gbits a sec. I was like yeah that's way m...
There are some smartwatch oriented MCUs has MIPI interface though, like the one on Arduino Pro
But limited lane count, one or two lanes
lilac tusk
CrossLink FPGA from lattice semi have 2 MIPI and 2 CSI hardened IP blocks
Which is cool
wraith thunder
WoW 1.35 USD per chip
dry shore
DSI also has some power saving modes
in one mode, DSI lowers the link rate (below 500mhz), so the bits/sec is just enough to drive the screen
but now the high-speed clock is running full-time
wraith thunder
Crosslink cost 10x of that and not mentioning the license cost for IP : P
dry shore
in the other mode, DSI will burst a scanline over at max datarate, then turn the clock off
lilac tusk
I’m not suggesting using an FPGA lol
dry shore
and it will send bursts, at the hsync rate
the idea being, 500mhz for 10% of the time, is lower power then 50mhz 100% of the time
lilac tusk
Just more of kind of cool that it has those things
sand lotus
so basically sandboxing it with the samd21
lilac tusk
Seems like it
wraith thunder
Does the backlight driver hookup to the linux backlight driver?
open girder
we think maybe we could? but we havent looked into it yet…ideslly we could over the DSI I2C!

That would be neat to hook it into dpms
So it would listen to the standard way of sleeping the display and waking it back up
