[adafruit/circuitpython] New comment on issue #9541: RP2350: hardware issue: stuck inputs

Apologies, I wasn't very clear. I was assuming the touchio API needs to stay consistent with the many existing guides (and, selfishly, the 100+ already-assembled PCBs I sell). Thus, to support pull-ups and pull-downs at run time, touchio would need an optional new argument to TouchIn() or a new class. This would make shared-module/touchio change, which would impact all implementations of touchio, not just RP2.

[adafruit/circuitpython] New comment on issue #8974: AudioMixer with effects

Putting some ideas down both for others to critique and to organize my own thoughts:

This is basic code to play a note:

audio = audiobusio.I2SOut(...)
mixer = audiomixer.Mixer(voice_count=1, channel_count=1,...)
audio.play(mixer)
synth = synthio.Synthesizer(channel_count=1, sample_rate=44100)
mixer.voice[0].play(synth)
note = synthio.Note(261)
synth.play(note)

There are two potential ways to add effects. The first as tannewt suggested:

[adafruit/circuitpython] New comment on issue #8974: AudioMixer with effects

First, this is very cool!
I like the .addeffect() technique a bit more, for the reasons @gamblor21 mentions, but I'd rather have it add to Mixer instead of Synthesizer, so that other items played with the mixer can get the benefit of the effects. (Many physical mixers do this, having effects busses you feed channels into)

So that would I guess look like:

echo = audioeffects.EffectEcho(delay=50, decay=0.7) # define an echo effect
mixer.voice[0].play(synth)
mixer.addeffect(...

[adafruit/circuitpython] New comment on issue #9541: RP2350: hardware issue: stuck inputs

@todbot The plan I had in mind was to switch at compile-time, for RP2350 only, to supporting a weak pull-up rather than a weak pull-down. That would be documented, so any RP2350 hardware would need to use it that way. It would not be an option to switch at run-time between the two methods. I just was testing it on RP2040 to see if the idea worked.

We might support an informational TouchIn.pull_needed read-only parameter, which would return digitalio.DigitalInOut.Pull.DOWN, .UP, or `N...

[adafruit/circuitpython] New comment on issue #8974: AudioMixer with effects

Anyone have any thoughts? Are dynamically changing effects a good idea? Would we want effects on a per channel basis in the synth?

I think it's important to think about how you'd remove an effect as well. I do think we want to change them dynamically.

I don't think we need them on a synth channel basis. Instead, you can have two synths.

That's not what I meant. I was responding to "Would we want effects on a per channel basis in the synth?".

I still think the best way is through separate intermediate objects that get played.

I'm not sure if I'm seeing this same bug. I don't believe my program is using ADC (yet).

I've been experiencing infrequent but repeated watchdog timer resets on my ESP32-S3 Reverse TFT board running CircuitPython 9.1.1. By infrequent, I mean my program typically runs for one or more days before a watchdog reset halts it.

Although my program initializes an ADC AnalogIn on board.A5, it never actually reads it (I will be using it eventually).

+1 on @tannewt 's suggestion of running audio buffer sources through the effect and then to the final mixer object before the output. In a way, I think it is reminiscent of guitar pedals as to how you'd chain them together. Though I know the naming scheme we're playing around with isn't final, I think audioeffects.EffectReverb is somewhat redundant and should be more like audioeffects.Reverb.

[adafruit/circuitpython] New comment on issue #9291: ESP32-S3 ADC use causes crashes when WiFi in use

@steveputz When 9.1.3 came out because it has an updated ESP-IDF, I tested the ADC functionality but still crashed for me when reading ADC values. So might be best to wait for 9.2.0-alpha.2352 if it is going to include another ESP-IDF update. However I don't know of any good reason not to upgrade from 9.1.1 to 9.1.3. I tend to always install the latest stable version whenever I am working with a board and sometimes the latest development release when the mood strikes me. So far so good.

On Monday we discussed internally what to do about the E9 workaround for CircuitPython.

Without adding additional API specifically to support the RP2350, there is no way to inform CircuitPython in various use cases, "well, yes, this is a weak input signal, so do the workaround". The only hint would be if you enabled the internal pulldown, but there are other cases as well. We do not right now want to make a special-case API for the RP2350.

I like the direction of this. I want to point out we probably want more specific module names instead of audioeffects. That way we can have more or less on different chips.

Would more modules be preferrable over having flags to turn on/off individual effects within one module? I would think we would still want some broad categories and not one module/one effect? New modules aren't hard so no real preference from me. Something that doesn't have to be decided this moment still at least.

Oh Great and All Knowing CircuitPython guru's:
is there a way to stop a property being evaluated when I press tab in the repl on the parent class object.
The crickit sets up everything when the repl evaluates it, including a stepper motor on the motor pins when the stepper_motor property is evaluated, i.e. pressing tab on crickit object to see whats available. It has undesired consequences, but if there's not a solution that's okay.

#

I tried some lazy-loading-like shenanigans but failed to achieve the goal of have it (stepper_motor) not run when evaluating crickit's children, while still work as expected when assigned to a variable or directly evaluated to see it's children/used in the repl (rather than as a child property of crickit). https://github.com/adafruit/Adafruit_CircuitPython_Crickit/issues/39

Was that hope based on reading something in the release notes?

No, just on testing.
I retest everything i'm concerned about after idf / micropy updates.

The idf release notes are incredibly long.
I physically don't have the time to read them.

The wording "I hope" was chosen because of the bluetooth workaround, which patched it, till enabling bluetooth became conditional, making me feel uncertain as to if the issue is really gone.

I've done a little digging through the CircuitPython source code and I suspect that it's a NimBLE error, in which case it would be an Invalid HCI Command Parameters error (0x212).

It doesn't look like @eightycc has pushed their WIP code. It is up to them.

@slender iron pico w is 1.5MB I think, it was a compromise to fit all the wireless & ssl stuff. it'd be nice to enable ssl on pico 2 so it can be used with wiznet ethernet. for instance. but also thinking of the future, it's 80% full or something.

[adafruit/circuitpython] Pull request opened: #9616 Three fixes found for ESP32-C6
  1. Correctly free memory used by ESP _bleio.Characteristic by adding deinit().
  2. Correct gc_alloc_possible() because it was true after the first VM run and caused BLE characteristic allocations outside the VM to occur on the VM heap.
  3. Clear the serial RX buffer when receiving a CTRL-C. Without clearing it, you may skip straight to the REPL without the "press any key" prompt. The file transfer over serial stuff looks for the "press any key" line.

[adafruit/circuitpython] New comment on pull request #9583: Remove ESP_CONSOLE_UART from sdkconfig for 666 S3 Display panels

It looks to me like in addition to the Hacktablet and Makerfabs TFT 7" boards, the Espressif ESP32S3_LCD_EV and possibly (I don't know if non-S3 boards are affected) the Lilygo twatch_2020_v3 may be affected by this issue. I don't have either of those devices to test with but I'm happy to update the PR to include the same changes for those two boards as well.

There is a big difference in build size, like 1800 bytes for Feather M4, which is causing some build failures. I'll investigate that.

Most of that was due to the new ulab.numpy.random, which I turned off everywhere, at least for now. Another 100 bytes or so was due to adding the e type code to struct, etc. This is a 16-float format that is in CPython. That 100 bytes pushed some almost-full boards over the edge. I will see what I can do.

I know you can change the volume(gain) using the circuitpython mixer object. However, there are a few reasons that I think it should also be added to the audioio object:

  • Better preformance. I've tried to make a mp3 player on the Adafruit Pygamer but adding a mixer slows it down too much so the audio sounds poppy and choppy. Changing volume is really just multiplying all the samples by the volume. So one float multiplication built into the audioio module will probably be faster than having...

[adafruit/circuitpython] New comment on pull request #9340: Rotate display on Sunton ESP32 2432S028

Is it possible to add a display rotation property to settings.toml (or whatever is used for setting WiFi credentials)? That way, if a particular board needs display rotation, we do not need multiple versions.

I suspect settings.toml is read prior to the execution of board.c (I'm not sure though). Even if it is, it's probably not worth adding the additional code (firmware space) to the core to carry a parameter forward to support screen rotation options.

That being said, it is possib...

The settings.toml is read every time you access a variable defined in it, so I think there should be no problem getting it in board.c. I have done a similar thing on my PewPew M4 boards that can use displays with different initialization requirements, but in their case the display parameter is stored in the UF2 bootloader: https://github.com/adafruit/circuitpython/blob/main/ports/atmel-samd/boards/pewpew_m4/board.c#L93-L95

If the grouping desire is based on memory usage, then perhaps grouping names that imply "no buffer" vs. "small buffer" vs. "big buffer". e.g. "Compressor" would go in the "no buffer" group, "Chorus" in "small buffer" and "Reverb" in the "buffer" group.

@onyx hinge @slender iron I was looking into something, and found out that some interesting C23 additions to the C language are in gcc 13. Various refs to this, but this is a nice but incomlete summary: https://lemire.me/blog/2024/01/21/c23-a-slightly-better-c/. Maybe you know this already.

  • #embed: like
const uint8_t image[] = {
#embed "image.png"
};

See https://gcc.gnu.org/onlinedocs/cpp/Binary-Resource-Inclusion.html.

  • constexpr, e.g. constexpr int LIMIT = 12 * 3. The expression (no function calls allowed) must be constant at compile time.
  • int x; typeof(x) y;. Those are two declarations. That declares y to be the same type (int) as x;
  • static_assert(LIMIT == 36): causes a compile warning if false.
onyx hinge
#

those are all nice features. Many had alternate ways to accomplish them such as enum { LIMIT = 12 * 3 }; (C99 compatible), MP_STATIC_ASSERT (C99 compatible macro). typeof() has long been a GCC extension.

#embed is a convenience. constexpr might have some interesting applications.

i went down this path due to thinking yet again about how to do cheaper compilation of translations. The things above don't really help, though.

Is anyone able to usefully try the memorymap example for rp2040 that sets pin drive strength? On a pi pico (1) I find that get_pad_drive doesn't return the value I set a moment before. A modified set function does seem to work, so maybe the problem lies in the implementation of set_pad_drive ```py
if d not in range(4):
raise ValueError(f"invalid drive strength {d}")
pads_bank0 = memorymap.AddressRange(start=0x4001C000, length=0x4000)
pad_ctrl = int.from_bytes(pads_bank0[p4+4:p4+8], "little")
pad_ctrl &= ~0x30
pad_ctrl |= d << 4
pads_bank0[p4+4:p4+0x8] = pad_ctrl.to_bytes(4, "little")


(I was testing first on rp2350 which puts the registers at a different start= but that's a whole different thing)

aha figured it out -- the offset for "atomic xor register" is 0x1000 not 0x3000! pads_bank0[p*4+0x1004:p*4+0x1008] = pad_ctrl.to_bytes(4, "little")

@wanton dirge Are you getting close to PRing the max support?

wanton dirge
#

Still working on adding some basic module support and then considering what additional HW to port on...would you prefer a "bare" PR that adds basic support and then separate PRs later for digitalio, busio, etc? In addition to more for separate boards?

I'd say depending on what you'd deem necessary for a base PR I would likely target e.o. next week timing-wise; I'm currently in Ireland for some tech training 🙂

@BennettB123 I tested this with an Adafruit Metro ESP32-S3, running CircuitPython 9.2.0-beta.0. I connected some ~4-inch jumpers with alligator clips at one end to D8 through D11. Touching two alligator cips with one hand and two with another produced raw values of 65535, as expected, but the loop was still running very quickly. I also tried clipping coins with the alligator clips, and that made no difference.

@dhalbert Thanks for testing! I went ahead and upgraded to 9.2.0-beta.0 to rule out differences there and I'm still getting the same behavior. One thing I may not have made clear is that the loop still runs very quickly when I'm touching several pins. However, the actual raw_values don't update every loop iteration like they do when no pins are touched.

I'm still digging into the code, but my first instinct is to have the delay_ms property just be a float in seconds as delay instead (ie: rather than 500 ms use 0.5 s). The calculation that is being used to allocate the buffer uses floating point regardless.

I looked at this with a Saleae. On ESP32-S2, the I2C bus frequency is only 1.25 kHz (!), even though I requested 100 kHz. This is apparently due to some bug in ESP-IDF v5.3.1 (used in CircuitPython 9.2.0), which switched things around under the covers for the legacy I2C driver. It's fine in ESP-IDF v5.2.2, which is used in CircuitPython 9.1.4.

# devout jolt Answering my own question maybe: It seems that `circup` has the concept of `modu...

I do think that circup expects a "plain" semantic version string with specifically 3 numbers seperated by two periods and nothing else (so the leading 'v' would throw it off I think.)

The other "gotcha" that I am aware of is that the versions are only embedded within "released" library artifacts in the bundles. So if you clone a repo and then simply copy/paste the code to your device you'll end up with a copy that is version 0.0.0 and circup will always update it because presumably it will always find a release newer than that. For that reason I actually don't tend to use the update command within circup that much because I often have modified versions of the libraries on my devices that are from a PR or some other local development work and I don't want them all to be overwritten by real published versions.

there is a lot of preprocessing of the source that happens to extract the strings. But we don't compiled altered source. The MACRO actually turns into a huge if (or case?) statement that the compiler turns back into a constant.

In general, is there a straightforward-ish way to check some web page to determine which release version of tinyusb is included in a given release of CircuitPython?

I tried looking in 9.2.0 beta release notes and on github, but I guess I didn't look in the right spot? I'm wondering if the new tinyusb 0.17.0 release will end up in CircuitPython 9.2.0. Going by the 0.17.0 release notes, I think the changes for MAX3421E support may unlock a bunch of new USB wireless gamepad adapter stuff that I failed to get working previously. So, I'm really looking forward to 0.17.0

I think you could adjust your initial allocation to be larger if given a non-fixed value. That way you don't need to re-allocate when the value changes. You just don't use all of the buffer for short delays.

I also think it's good to show how to use BlockInput so that further effects use it too. It is more complicated, but it'd be good to show how to use. It is super powerful IMO.

Looking at the code, it looks to me like the slot is determined by the command and clock pins. there also appears to be data pin requirements depending on which slot is being used. I haven't dug through the Espressif documents to verify but if you think that's more restrictive than the peripheral requires (which the comment does suggest) I can try and figure that out.

I believe, currently both slots could be used by selecting the associated gpio pins for each slot?

@slender iron Question about add16signed and mult16signed in Mixer.c. I get they let you work on both halves of a 32 bit value. Was this mostly because Mixer wouldn't care if the two 16 bit values were left/right stereo or mono/mono samples?

Asking because I'm thinking for the effects it may make more sense to work 16 bit sample by sample (though need logic to deal with # of channels) because then like synth does values may exceed 16 bits and be brought back into that range.

It seems that there are a few different variations of bad actors opening issues on open source repos that have comments containing malicious links. Some claim to have found security vulnerability in the repo, and others try to mimic a message from Github staff. I'm sure they've got other tricky varieties of messages as well. These issues are created in order to send out the email that goes to maintainers in the hopes they'll follow the link in the message. Here is one article discussing this tactic https://www.bleepingcomputer.com/news/security/clever-github-scanner-campaign-abusing-repos-to-push-malware/

I thought it was worth mentioning here so everyone is aware and warn to be wary of any links that come via Github issues, PRs or comments.

If this happens again, could you run fsck -VN just to report with what fsck thinks is wrong? I am thinking that the drive is being dismounted when it is an inconsistent state or the dirty bit is set. The latter should not make it be read-only, but there may be some defaults on your system that are causing this. I am not sure that blinka has anything to do with this. The volume label manipulation you mentioned above may also have corrected some other issue as a side-effect.

I will do so...

This time my "solution" did not work. Also did fsck -CVlr and did not work.
If this keeps up I can not use the pico as it (or something) is too unstable. Works better if it is plugged into a fedora machine. Mounts read-write more often.

It seems to me very unusual that Pi Zero W shuts down sometimes when you plug in the Pico W.

If you disconnect everything from your unusual power supply but the Pi Zero W does it happen?
If you use a more conventional wall wart power supply (say 1A or 2A), does that happen?
If you swap out the Pi Zero W for another Pi Zero W, does it also happen?

These are all things I would try in an effort to isolate the problem.

The answer is no to all of those questions. I suspect those are in fact due to my complicated power supply (solar weather station)

But I have a clue about the mounting read-only problem.
At one point I thought the pico had crashed but it was just stuck in the repl after a crash. When I learned how to use the program "screen" I could differentiate between these crashes and real lockups.
There is another problem "real lockups" where what I think is going on is you are disconnected from...

  • Wrap the entire program in a try-except that catches all exceptions. This could be something like:
try:

You can put the main program in do_everything(). That makes the code a little neater. However, if you have a lot of globals, this might force you to restructure the program, so the alternative is just to wrap the...

# tulip sleet it was right after a new library was merge in

In this case I think the newly added libraries are a red herring. It seems a recent commit in one of the previously added libraries causes circuitpython-build-tool to fail https://github.com/adafruit/CircuitPython_Community_Bundle/actions/runs/10969895769/job/30463140170#step:8:42

I think the root cause is a recent commit to https://github.com/buildwithpiper/circuitpython-piper-make-library which made a change in one of it's root files. Build-tool doesn't support multiple root files for a library. They must be either in a single file, or refactored into a python package folder.

However there is still a bit of a mystery involved as well. I don't see any clear reason why it just started failing now. The second root file was added ~7 months back it appears to me, and somehow didn't cause any issue at that time. But a few days ago there was a change made in the original root rile (not the newer one) and that leading to the build failing.

I'll open an issue on that repo see if the owner is willing to refactor to a package.

In the medium / longer term it might be nice to update build-tool to be more forgiving of failed builds even if just for the community bundle. If it could make note of the failure for a particular library but continue on and build the rest of the bundle successfully I think that would be ideal.

[adafruit/circuitpython] New comment on issue #9651: Add LDO Voltage Regulator module (LDOPWR?)

I'll take a look at memorymap but at first glance, figuring out how to interface the LDO via memory manipulations would take me deeper into the IDF than I ever expected to go :grin:

The issue is sort of board related as it depends on how the chip is wired up to an SD card slot (or other SDIO peripheral) so maybe before deep diving the IDF, I'll see if I can create an object in board/board.c, maybe board.LDOn, similar to how board.DISPLAY is created.

[adafruit/circuitpython] New comment on issue #9623: Add master volume to Audioio

I have been spending a lot of time deep-diving into the audio code lately and I'm not sure if moving it from Mixer to anywhere else will see much of a speedup. As is the Mixer code basically only does what you describe, multiple each sample by a value. I'm not even sure there is room for much optimization in there.

The other issue is the audioio code is port specific so would have to be done for each port.

I do not have a PyGamer so cannot easily try it out unfortunately.

I need to grab a screencap of it from my scope, but now I understand why the official workaround for RP2350-E9 is not useful for making touchio work.

Relative to the pull down current (I think I was using a 3.3M resistor to GND), the amount of current injected when the input buffer is active is substantial. touchio wants to poll the pin as frequently as possible, but activating the input pad for just long enough to read the pin value injects a substantial amount of current, and the voltage STILL settles at around that +2.2v even if I enforce a minimum of 10us with the output buffer disabled.

For this particular resistor and inherent capacitance, a 50us delay with the input buffer off makes touchio "kinda work", but there's no value that would "work for sure" because it's highly dependent on the RC constant of the particular setup.

#

What happens if you try to work around the E9 erratum via the input pad enable bit. With this particular resistance & capacitance, the ~120ns the IO pad spends enabled is almost able to recharge as much as the resistor discharged over 20us.

120ns is 18 clocks @ 150MHz so while it could maybe be a bit shorter it is already pretty short & enforcing an arbitrary minimum delay after reading any pin is pretty terrible. However short the input buffer on time & however long the forced IO delay, some R,C values would still be problematic...

that said, with this hack touchio kinda works in this one particular circumstance, it reads ~60 no-touch & 100 to 600 with touch.

@tulip sleet I agree, it's not worth it to try to get touchio-with-pulldowns to work right now. Until performing this experiment for myself I didn't yet understand WHY the workaround wasn't useful for touchio.

Can you please combine the fill_buf_info_{read,write} routines? I notice you've added detection of mismatched stride between the "once" and "loop" variants, which should probably apply to write as well. I think you'd just have to add the access type parameter and pass MP_BUFFER_{READ,WRITE} in.

Or is there a reason the new checking you added should not also have been done for the background write case?

Word to the wise... 44.1Khz dual channel audio with asyncio without enough sleep in a loop causes weird stuttering that you will try to debug all night long, and turns out just add a small delay to the sleep loop and you are good. Maybe a sign a 0 asyncio.sleep isn't running audio tasks fully?

But it did prompt me to add double buffering in.

adafruit_register/i2c_bcd_alarm     demos/othello     paralleldisplay   ulab.scipy.signal
adafruit_register/i2c_bcd_datetime  demos/snake       paralleldisplaybus                  ulab.scipy.special
adafruit_register/i2c_bit           demos/sokobon     picodvi           ulab.utils
adafruit_register/i2c_bits          demos/tetris

And by size, just the size of the uf2 that gets output

#

are you freezing in some extra libraries?

#

the freezing process will discard stuff in examples/, but not in demos/

modest hazel
#

I didn't intend to - and yes, it is a custom build. I'm not sure how those got frozen in, though.

tulip sleet
#

did you add frozen modules in mpconfigboard.mk?

modest hazel
#

For the Raspberry Pi port, yes, but I didn't edit the one in the /py/ directory.

tulip sleet
#

could you point me to your mpconfigboard.mk?

modest hazel
tulip sleet
#

so, those libraries are not in the "standard" format. The build process that freezes the frozen modules assumes that directories in the libraries should be frozen, except that it discards code in examples/ (and tests/ I think). Your examples are in demos/, so it thinks that directory is a regular part of the library

#

same if you called it wonderful_stuff/ ,etc.

modest hazel
#

Ah - okay, got it - I didn't connect work done by an author a few years ago to what it happening!

#

So just renaming the folder to examples/ in the library should do the trick?

#

I actually forgot those demos were in there - I thought it was something to do with makecode arcade or something like that 🙂

tulip sleet
#

looking...

#

yes, just rename demos to examples

#

and you will need to update the submodule commits

modest hazel
#

Got it, thank you so much!

@tulip sleet Just found this, and indeed I'm using "adafruit_huzzah32_breakout" as a generic board to get CP up and running on my https://www.waveshare.com/e-paper-esp32-driver-board.htm. It's working like a charm. feather_huzzah32 works too, but didn't define all pins. One request, it seems like the Built-in modules between the two boards aren't the same. I can confirm because I can't use "alarm" with my board. After digging it seems like CIRCUITPY_LEGACY_4MB_FLASH_LAYOUT is the culprit. The comment in mpconfigport.mk says you're moving away from that. I'm wondering if that's going to change for the adafruit_huzzah32_breakout port? Or will I have to make a one-off build for myself.

When you mount by mount command over an ssh, the default mount action is read only.

This is strange and certainly not "default" for Linux. I work with ssh on all kinds of Linux boxes and I never experienced this issue. It does not mean that there is not some voodoo added by Ubuntu that triggers this behavior.

Can you reproduce the issue on Ubuntu installations without graphical environment ("Ubuntu server")? If your boxes are remote, you should not need the graphical environment afte...

hi, bablokb
My IT person disagrees with you on the default setting. I'm just the middle-man app developer (please don't shoot the piano player :-).
I have not tried this on a system without the GUI, we are not using that type of system, all our remote boxes are full-up linux boxes (whether for GPUs (jetson based) or low price rasbperry pi based (onlogic)). Mount has to be by sudo. My IT guy is hesitant to edit the /etc/fstab and I've asked/told him several times previous to this that this...

hi,
Haven't checked journalctl, will do an experiment sometime today, my IT guy shows up later in the day too.

I'm running the bespoke dev board against a linux DELL laptop, basically pretesting because once the app is copied into the box, and the box is closed and placed, everything gets way more difficult to test. The remote lboxes will be the same linux version but there will be to-be-discovered differences because of differences that are related to the processor unit vendor choic...

This is definitely not a CircuitPython problem, but a problem of your system configuration. I just logged into a remote Pi system running a GUI, and mounted a Pico-W running CircuitPython without any problems:

The first command sudo lsblk... lists all the drives and you can see /dev/sdb1 as the Pico-W with CIRCUITPY. The second command sudo mount ... does the mount without any special options (and the device is not in /etc/fstab either). The third command sudo findmnt ... shows all...

@schaefer01 The permissions problem you describe sounds similar to trouble I had mounding CIRCUITPY over SSH with Debian 12. Debian and Ubuntu are similar enough that it might be the same problem. In my case, the solution was to use pmount and pumount.

I handled mounting and unmounting of CIRCUITPY with a Makefile including these rules:

# Path to CIRCUITPY on Debian
D_CPY=/media/CIRCUITPY

# Mount CIRCUITPY from Debian command line (works over ssh).
# You might need to do `su...

This really boils down to the policy you have. You said "mount has to be by sudo". If this is true, then pmount won't help either, because this tool does not need sudo.

Another solution: since you have GUI boxes, why not use a vncviewer to connect? From a system perspective, this should then be a local login.

Anyway, there are multiple solutions to your problem. Your IT guy just has to pick one. Installing programs, changing polkit-configurations, adding a line to fstab, keep you walkin...

@tulip sleet @candid sun in the meeting yesterday I said I understood what Limor was saying about clock rates for pixel data vs everything else, but I think it turns out I don't. That is, I don't think we can control those separately in CircuitPython...

tulip sleet
#

That was my impression too, that's why Scott had to increase the clock rate on the Qualia to get it to stop tearing.

#

if we are talking about the same thing

onyx hinge
#

no, this is about display corruption on a fourwire st7789 display

tulip sleet
#

could you just change the SPI speed when sending pixel data?

onyx hinge
#

What Liz is seeing (I didn't reproduce it) is in a demo with pico 2, the camera cowbell, and an eyespi tft. Liz tried clocking down the SPI clock (from about 20MHz to 10MHz) and still saw it. But didn't see it in a modified demo that doesn't use the camera. She filed an issue yesterday if you want to look at the details

candid sun
#

it's super weird and i'm actually going to try a second pico 2 just in case

onyx hinge
#

I made a similar setup but didn't see any problem during the time I let it run. She was seeing problems as frequently as every 5 minutes (which would be about 1500 full display refreshes)

candid sun
#

i also want to check the original pico's SPI speed to see if it's slower because i hadn't seen it happen on the original pico when i initially used the example for the camera picowbell guide

onyx hinge
#

@candid sun (unrelated) did you test any epaper with pico2 or feather rp2350?

tulip sleet
#

that is a lot of stuff to power from a USB port, I wonder if it's a power issue

#

i am talking out of my hat

candid sun
stuck elbow
#

the st7789 should be fine up to 40MHz for writes, btw

#

reads at 20MHz

candid sun
#

i also saw it with an ili9341 fwiw

stuck elbow
#

same

#

might depend on the wires though

onyx hinge
#

eyespi 100mm ribbon cables in both our cases, I think.

candid sun
#

yes, same length

onyx hinge
#

what's different about the camera vs no camera situation is that the camera is also pumping a lot of data on nearby pins...

#

anyway with epaper this is what I'm seeing, corrupt top lines and the whole image is shifted down. the same code on a feather rp2040 doesn't ever update the display so that's not a great double check

#

@slender iron does this kind of thing ring any bell? it's a new https://www.adafruit.com/product/4195 so I'm using the code under "Newer 2.13" 250x122 Monochrome Breakout and FeatherWing" on https://learn.adafruit.com/adafruit-2-13-eink-display-breakouts-and-featherwings/circuitpython-usage

Adafruit 2.13" Monochrome eInk / ePaper Display FeatherWing

Easy e-paper finally comes to your Feather, with this breakout that's designed to make it a breeze to add a monochrome eInk display. Chances are you've seen one of those ...

Adafruit 2.13" eInk Display Breakouts and FeatherWings

Easy E-Paper With Built-in Memory

#

though I spot this note now: # For issues with display not updating top/bottom rows correctly set colstart to 8

stuck elbow
#

yeah, that looks like just uninitialized data

#

not corrupted data

slender iron
#

if the display is breaking at 10mhz you could use a saleae to capture it

slender iron
onyx hinge
#

huh actually using colstart of 0 fixed my display. OK, whatever

slender iron
#

the eink display products aren't well labeled to know the exact setting you need

onyx hinge
#

I dropped a feedback on the guide page but it may not be super actionable then.

candid sun
#

yeah it's always a little Tricky to get them setup right

onyx hinge
#

thanks

slender iron
#

we can do a better job with the next eink rev I think

#

I don't think limor expected the displays to change chipsets as much

onyx hinge
#

@slender iron any idea how in a saleae trace you'd FIND where it goes wrong? If you hit stop within 1 second that's still 10 million clock cycles to look through and interpret.

#

I suppose you could clock out 0xAA (not using displayio, but with the camera active) and see if saleae sees any anomalies != 0xAA), or just look at the pins in analog on a real scope while the camera's running to see if there's a significant amount of noise being injected

#

but it sounds like just running the display at around 20MHz should be fine

slender iron
#

you could parse the data captured to reconstruct the image

#

or validate the commands

onyx hinge
#

yeah it's not that there's a stray messed up pixel, it's (my interpretation) the display getting reconfigured inappropriately

slender iron
#

that was limor's guess too

#

accidentally changing your ram region for example

onyx hinge
#

typical clock data (D9) pin measured near the camera cowbell (camera data does not seem to be the problem)

image.png image.png
#

typical DC pin measured at the header nearest the connector

image.png image.png image.png
#

typical MOSI

image.png image.png
#

none of these traces look like they should be problematic

slender iron
#

I'd look at the logic level trace first

onyx hinge
#

I appreciate your POV, I was doing this test to see if there was an obvious big problem that looked like camera data showing up in the display control signals. especially since I can't reproduce a problem here, trying to look through a bunch of data in saleae for a needle in a haystack -- especially since who knows if the saleae logic levels exactly match the display -- was not where I wanted to start

#

but since all I see looks like the totally normal overshoot of logic transitions and not injected noise from nearby traces my theory is not looking too useful

#

@candid sun I assume you tried re-seating the eyespi ribbon cable at both ends during this process

#

while poking around with scope probes I did get a distorted image but I very likely bridged two pins briefly to cause that.

candid sun
#

@onyx hinge yes, also tried a new cable. i'm starting to assume it's something with my setup that i'm missing

onyx hinge
#

@candid sun if it's something that doesn't happen 100%, it'd be good to know if it happens 95% or 5%...

#

you also noticed we weren't using the same camera module, they might be different in a relevant way?? many unknowns especially until someone else has reproduced it

candid sun
#

hrm true true

onyx hinge
#

I'm gonna take a break and leave this running for a couple hours.

candid sun
#

i appreciate you looking into it!

blissful pollen
#

Just saw all these messages now, but is this ST7789 tearing similar to what was seen with the FunHouse a couple years ago? Not sure if it is related but sounds similar

tulip sleet
#

@onyx hinge do you remember any particular issue getting the autofocus firmware to load? I see you sped it up at some point by writing in chunks. With the old I2C driver, it loads fine, with the new one I get _OV5640_STAT_FIRMWAREBAD after loading. I've tuned up the loading process and tried various delays, changed the chunk size and went back to writing one byte at a time. Not asking for detailed analysis, just if something seems familiar.

If I just skip the autofocus loading then it doesn't take pictures: I get None back as the image.

I did a bunch of instrumentation. The I2C writes do indeed seem to be happening in common-hal, etc. I will do some Saleae tracing later.

onyx hinge
#

That's odd. the firmware shouldn't be needed just to take images. The transaction size was something that I arrived at empirically but it was just less than a power of 2 or something like that so it seemed to make sense

tulip sleet
#

i get reasonable values back when reading data from the camera, so I think I2C is working in general, and I2C to other devices seems absolutely fine.

#

that's what I thought. There are a few other tricky bits: the python code was not using write-then-read, but separate write and read, but that didnt' fix it.

#

thanks
