It may depend on your JTAG connection... going through OpenOCD seems to allow access to the additional registers.

@idle owl An issue on the Adabot repo mentioned adding the count of good first issues to the weekly stats generated by adabot. Do you think that would be a worthwhile thing to do?

[adafruit/circuitpython] Issue opened: #2508 time\.sleep\(\) rounds down to next lower millisecond

Delays are shorter than expected, due to rounding down, and coarse millisecond precision.

This code gives a 125 Hz waveform, but should be approx 100 Hz.

import board
import digitalio
import time

led = digitalio.DigitalInOut(board.D13)
led.switch_to_output()

while True:
        led.value = True
        time.sleep(0.005)
        led.value = False
        time.sleep(0.005)

@onyx hinge I'm interested to see how you approach it. I did take the "never distort" approach. And that 16bit unsigned...no CMSIS and my lack of assembly kept me from getting it done "fast". ๐Ÿ˜

[adafruit/circuitpython] Issue opened: #2509 "Cannot remount '/' when USB is active\." even when USB disconnected \(nRF52840\)

I'm getting a "Can't remount '/' when USB is active" error, when calling storage.remount("/", False) , despite the fact USB is not connected while the command is running.

Steps to reproduce

The board has to be battery powered, so that it keeps running the code even when USB is disconnected.

  1. Get into CircuitPython REPL (over USB-CDC)
  2. Type the following code:
import storage
import time
try:
  time.sleep(15)
  success = False
  storage.remount("/", True)

oops I think I just hosed my IS31FL3731. I had read the docs which said the panel was symmetric so I didn't think twice when attaching it to the driver board. the driver board is upside down. #lfmf

#

if only I'd actually followed the online guide I couldn't have made this mistake, since they soldered the "control port" connector first

@pastel panther It seems like there's a way to get the stuff in curly brackets to autofill. How do I do that?

@trim elm what? I need a bit more context

you mean the cookiecutter?

did you use cookiectutter?

What?

#

lol, one sec ๐Ÿ˜‰

Oh yeah, I used the setup.py from that, but in the setup.py there's a bunch of lines inside curly brackets, with what appears to be some python, like this keywords='{{ kw_list.kw_list|join(" '\n'")|indent(width=13) }}',

#

@pastel panther And it seems like the purpose of that is to automatically generate part of the setup.py. Is that the case, and if so, how do I do that?

Oh, wait, you said to read the readme

@ionic elk why not get a jlink from the store?

ionic elk
#

I could do that, which one do you use?

#

I mean is it way better than a BMP? Because that was fine too

#

though this lack of correct registers might be a build / GDB problem

I haven't used BMP. I don't think they've added SAMD51 support

re ANCS, test the setup py with my prior instructions. lmk if you need them again

slender iron
trim elm
#

@pastel panther the only commit since the last release (initial release which had already been migrated to Actions) was just updating the build badge, and it's already on pypi. Do you still want me to do a release?

pastel panther
#

ANCS?

trim elm
#

Yeah

pastel panther
#

no, that's ok

trim elm
#

Ok

#

@pastel panther I'll finish up a forum response and then take a look at the Apple_Media issues to see if I think I've got a shot at fixing them

pastel panther
#

sounds good!

trim elm
#

@pastel panther I think I'll let @slender iron or someone else fix the pylint issues on that repo

@trim elm he asked for help getting it sorted out so I'll take a look when I can

he mentioned it would be a bit tricky so no worries

@pastel panther, yes, it is in the build now.

there is now "generic" touchio support, which is turned on for SAMD51 and nRF boards

and the code checks for the large-value (like 1Meg) pulldown resistor being present

and will throw an error if it's not

[adafruit/circuitpython] Pull request opened: #2510 nrf: Add bonding to BLE pairing support

BLE pairing now will store appropriate bonding information after pairing. A region of internal flash is allocated for this. It's a growing consecutive log of "bonding blocks", which store either keys or CCCD values (sys_attr values).

CCCD values must be restored to their values after pairing when a bonded connection is made; this is required by the BLE spec. So whenever a CCCD is written for a paired connection, we remember its value using the sys_attr mechanism in the nRF SoftDevice.

[adafruit/circuitpython] New comment on pull request #2404: STM32: Meowbit support

Ok, we sorted out the interrupt issue! The functions called by an interrupt are dictated by the vector table. The location of it can be moved so that one set of code can swap to another (such as a bootloader). In this case, the STM uf2 is correctly setting it but our start up code is setting it back to the original location! For reference it is the VTOR register in the system control block (SCB) that controls it.

@hierophect is now unblocked and will continue with this. It's great to sort ...

Does anybody knows why the "Feedback? Corrections?" button ask for anonymous contribution with no personal data? When I find something I don't like in the documentation, I like to point it out, but I would also love to know if this is taken into account, and if ever the guide improve, know about it. Why it can not be like an issue on GitHub?

[adafruit/circuitpython] New comment on issue #2508: time\.sleep\(\) rounds down to next lower millisecond

@PaulStoffregen Would rounding to the closest ms (or the current sleep resolution) be the fix you are imagining? Since folks can be easily surprised by 0.005 s rounding down to 4 ms, I think that is better than explaining it in documentation.

And if I might add to that fix an enhancement request: Increase sleep and monotonic_() resolution (as I mentioned above). Should that go into a separate issue?

@mcosti hmm, some kind of pairing issue mentioned here: https://social.technet.microsoft.com/Forums/en-US/31e39461-0b8b-4daa-86d0-010f0bd2feed/microsoft-surface-and-ble-issue?forum=win10itprohardware. The OP said it works with a dongle, but not with the builtin Bluetooth hardware. I assume you're up to date on drivers and the latest version of Windows 10, but if not, that might be worth trying.

I did not find many similar reports, but very few people are trying to use BLE HID with Windows....

we shouldn't need the adafruit_ble mocks

Ah, ok. Just doing a simple mock import wasn't working so I mocked it kinda like adafruit_circuitpython_ble does with _bleio, but if there's an easy way to get it to do it from pypi instead, then that'd probably be a lot cleaner

#

And that would also have the added benefit of the mock not needing to be updated if ble were to get a new feature that would require a mock update

[adafruit/circuitpython] New comment on issue #1050: nrf: implement BLE HID

According to the error code, the cause of the issue: the device's hardware key contains a "FailReasonString" value, and the value string is displays an error message defined by the hardware manufacturer. If the hardware key does not contain a โ€œFailReasonStringโ€ value the message above is displayed.

I think that is just saying that it's failing and we didn't supply a reason string ??

As far as I can tell i'm up to date on my drivers. I have 2 other Bluetooth HID devices (Pen digit...

hmm. Not sure about the PS4 game pad, I think that's older, but the Surface Pen is listed as using Bluetooth 4.0, and in device manager shows up in HID section as Bluetooth Low Energy GATT compliant HID. So, still not 100% sure, but most likely?

Is there perhaps some arduino BLE HID code I could try on the CPB instead to see if I get the same issue?

[adafruit/circuitpython] Issue opened: #2513 Unix port doesn't include many circuitpython modules

The unix port should have it's Makefile updated so that hardware-independent modules are included, so that tests can be added for them.

Please add modules you know can be added to the circuitpython unix port to this checklist.
We might also want to have a HAL that provides dummy hardware for testing code functionality too, but that will probably want a bunch of different issues.

@obsidian compass I have homebrewed my own thing while working on JEplayer. It uses makefiles and will mpy-cross the libraries you symlink into a src/ directory, and finally uses rsync to ensure what you have on the device is up to date.

@ruby atlas no, Rosie hasn't been running for quite some time. I have been slowly working through a replacement. My #circuitpython-dev2020 posts have some details.

obsidian compass
#

@stuck elbow that's right but during dev we can use host machine cli to fetch and put the .mpy library to /lib

raven canopy
#

I liked @ivory yew's point of going GUI over CLI for handling the package management. Using Kivy came to mind, so that it could be cross-platform. Not the only option, certainly.

stuck elbow
#

@obsidian compass oh, you mean on the computer's CLI?

there is a number of such tools you can choose from, the two most popular are called wget and curl

@raven canopy yes that's right ๐Ÿ™‚

@raven canopy anything but electron based app ๐Ÿ˜‰

I would do a multilayered thing. I'd make the core of the package manager a shared library and build CLI and GUI interfaces on top.

@ivory yew that sounds like the best way to do it, IMO

Latest library .mpy + latest firmware, therefore, no dependency colliosions.

@slender iron do you remember what it was that lead you to realize that VTOR might be the problem? I'm trying to make a note of how we ended up there. We were looking at the control registers, and then we realized something wasn't loading as it should have been...

#

After that I remember it was VTOR isn't right, it's being properly set by bootloader, watchpoint to determine it was changed in Reset Handler, then I guessed it was in system_stm32.

#

Was it just that it happened to be up on your screen as we were looking at SCB registers, and we noticed it was wrong?

orchid basinBOT
manic glacierBOT

#

@ionic elk I think it was because we were looking at what the bootloader did before jumping to the app

#

and I have svd on the STK already so when I saw SCP I tried it

@slender iron I feel like there was something that tipped us off that the vector table wasn't being loaded properly. I'm trying to remember what that was

ionic elk
#

some value wasn't set, or something

#

oh well

slender iron
#

well, we saw that the SCB->VTOR value was back to 0x8000000

#

and therefore it must have been unset

ionic elk
#

right, that was after, everything was pretty clear from that point on

indigo wedge
#

I pushed some basic code structure to https://github.com/arturo182/tinyuf2, it builds and "works" (blinks a led and usb interfaces show up) on the rt1011 evk, note that there is no uf2 code in there yet

ionic elk
#

We were looking at the control registers, then we checked out the memory to make sure everything was in the right place...

#

It's not super important though so nbd

indigo wedge
#

I'm thinking if we should reuse board definitions from tinyusb or make our own structure for that

slender iron
#

@indigo wedge my plan was to have a supplemental board structure in tiny-logic-friend

#

it won't be shared at all because it will include logic analyzer specific data

#

my plan today is to split out flash info from board info today in circuitpython

indigo wedge
#

i'm just thinking that right now if someone wants to add their own board they would have to make copy an existing tinyusb board folder and modify that and there would be a lot of copied code

#

like, look how easy it is to add a new board in the samd bootloader

slender iron
#

ya, I think we can factor things out as we go

indigo wedge
#

just 2 files

slender iron
#

ya, we can get there. imx rt is trickier because of the flash info

#

@onyx hinge what do you mean by underrun? running out of buffer to playback?

onyx hinge
#

@slender iron right, it alternately DMA's buffer A and buffer B to the DAC, so an "underrun" would be if it starts to dma buffer A (or B) but software hasn't filled it..

manic glacierBOT
onyx hinge
#

and in this case the hardware is going to just DMA out old data and the software doesn't know it. Except your audio will sound .. wrong and jumbled

[adafruit/circuitpython] New comment on issue #2508: time\.sleep\(\) rounds down to next lower millisecond

@kevinjwalters Yeah, utime is interesting. The functions returning wrap-around time can give new programmers headaches. The unspecified period can give everybody problems. If my code asks the question, "Has some length of time passed since this event of interest happened?", I want to feel comfortable that the counter has not wrapped around some number of times, but that the wrap-around time is much longer than the interest in the question. I'd rather not have to count wraps.

I understand...

slender iron
#

@onyx hinge do we keep a counter based on dma block completion? wouldn't a gap of >2 mean an underrun?

#

does the dma mark the descriptor as invalid on completion too?

onyx hinge
#

to the second question, I think no -- the B dma descriptor always points back to A and vice versa

#

to the first question, I don't know where we do that

slender iron
#

lemme look. somehow we have to know what buffer is being used atm

#

we use the event system to track when a block is done

#

and it can tell you when an overrun (?) occurs

onyx hinge
#

OK! I will look into what they term an overrun. I was looking at DMA in the datasheet, not thinking about event system though that makes sense in retrospect.

yeah @tidal kiln @slender iron it seems to be my thing. I'm not in the right headspace to respond right this second, and I'm not even sure what I would suggest. If adding a small sleep is an effective workaround, that is great and they should go for it.

#

@onyx hinge @slender iron @tidal kiln Also hidden in that discussion on the DAC is a pop with the mixer. Is the using responsible for attack?

slender iron
#

not sure what you mean by "Is the using responsible for attack?"

bright aspen
#

Uh, user.

onyx hinge
#

so say your sample is +4000 and you change the volume from .1 to 1.0, the DAC will change from 400 to 4000 in one step. Yes, that will sound like a pop.

bright aspen
#

Right.

onyx hinge
#

having the mixer spread a volume change over a short period of time is not an unreasonable request, I suppose, but the code is not written

bright aspen
#

Coding that might be easier than writing up how to do it in CP. (I have no opinion either way.)

manic glacierBOT
bright aspen
#

@onyx hinge @slender iron @tidal kiln One person's workaround was to use the mixer. Perhaps that effectively increases the buffer size? Arg. I'm kibitzing.

orchid basinBOT
onyx hinge
#

@bright aspen kibitzing is fine, I love knowing other minds are thinking about the same problem as me. I don't think that the mixer adds a bigger buffer, I think it's 1024 bytes (divided into 2 512-byte buffers) by default just like for a WaveFile. ICBW of course.

raven canopy
manic glacierBOT
bright aspen
#

@raven canopy @onyx hinge I'm just guessing at how the mixer works. I'm assuming everything is done on half buffers. I'm also guessing that a mixing change is done on the edge of that. So maybe a volume change can take place over a half buffer. That means a faster change with faster sample rates, though. If I wandered down a bunny trail...

#

My CircuitPython 5 poster arrived today. You can release it now.

Yes, I like microseconds. In addition to giving a false impression of precision is that what works on one board might not work as well on another. Those might be a documentation task. Even so, I favor a move to microseconds, if not for both sleep() and monotonic_ns(), then just for the latter.

[adafruit/circuitpython] New review comment on pull request #2510: nrf: Add bonding to BLE pairing support

I think this is safe, because the sd_ble_sys_attr_get() calls in write_sys_attr_block() will fail if the connection handle is invalid, and then write_sys_attr_block() will just give up in that case.

Interestingly the documentation talks about (ideally) fetching the values after the connection is closed to avoid churn. But someone may press reset, etc. So that's why I put in the one-second delay, which seems to cover the typical case.

@tulip sleet So this is weird: if you load the Circuit Playground library alone onto a CPB, and in the REPL from foo import cp it fails on a lack of lis3dh as expected. Drag lis3dh onto the board, go back to the REPL, from foo import cp it says

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
ImportError: no module named 'adafruit_circuitplayground.cp'```
I have to reload the REPL entirely by exiting the REPL and going back into it. Import again, fails on a lack of `thermistor`, again, as expected. `import cp` and it says the same `no module named 'adafruit_circuitplayground.cp'`. I have to exit and reenter the REPL again. Repeat until all the dependencies are installed, and it finally imports `cp` properly. ๐Ÿคท

and get: ['test.py', '{"one fish": "two fish"}']

#

So that second argument is correct. It's a dictionary definition with quoted key and value intact, passed through the os.system command and read from the argument list.

@wind trellis hmm... That might just work. Too tired to try it right now, but I'll give it a go tomorrow morning

Definitely not something to tackle when you're sleepy. Good luck with it!

#

@trim elm You can use the subprocess module to give arguments as lists instead of a whole command as a long string. subprocess.run(["curl", "--data", "{...}", "https://...."])

#

and yeah avoid starting subprocesses while sleepy

trim elm
#

@onyx hinge Yeah, I think that might be a better option than what I'm currently doing.

onyx hinge
#

or you could almost certainly use python3 requests package to send the request instead of curl

#

requests.post('https://httpbin.org/post', data={'key':'value'})

trim elm

That actually sounds like a great option. I've tried using subprocess for other stuff, and while it does have a lot of functionality, doing complicated stuff with it is very not fun

@idle wadi We had iBeacon and EddystoneURLBeacon working in a previous version of Adafruit_CircuitPython_BLE, but we need to re-create them, after redoing a lot of the internals of that library. It would be based off the current advertising code. See https://github.com/adafruit/Adafruit_CircuitPython_BLE/releases/tag/2.0.1-alpha.2 (which does not work with the latest betas). What kind of beacon did you have in mind?

[adafruit/circuitpython] Issue opened: #2522 Support 'R' prefix for raw string literals

Following the discussion on https://github.com/adafruit/Adafruit_CircuitPython_IL0373/pull/7

Circuitpython currently supports raw string / byte literals with the 'r' prefix but doesn't support the 'R' prefix.

This should be changed to support compatibility with CPython.

"Both string and bytes literals may optionally be prefixed with a letter 'r' or 'R'; such strings are called raw strings and treat backslashes as literal characters." (excerpt from https://docs.python.org/3.7/refere...

@indigo wedge thanks for fixing this issue.

A bit off topic but I am curious about is why micropython chose to implement the is_char functions receiving a mp_lexer_t pointer and not just pass the actual byte. Do you think this is because it is optimized away?

indigo wedge
#

Not sure tbh

ionic elk
#

I don't have a lot of luck using the displayio.release_displays() command. I still constantly get stuff like ValueError: SCK in use, etc. Does anyone know what's up with that?

stuck elbow
#

is that a fourwire display?

ionic elk
#

yes

stuck elbow
#

maybe the fourwire bus object is still lingering around somehow?

ionic elk
#

I'll look into that

stuck elbow
#

I remember it worked for me in 4.x, but I didn't test it in 5.x

ionic elk
#

specifically it seems that the display works fine up until you fail the syntax in some way, and then the first pin of the SPI bus will be perpetually in use.

#

So as long as my code works, everything is fine, but as soon as I make any form of error, it'll lock the display bus until a hard reset.

stuck elbow
#

that's on the stm32 or generally?

ionic elk
#

I will test generally now

stuck elbow
#

we had some reset bugs with exception handling before

main meteor
#

Correctly unwinding everything in an exception is annoyingly meticulous and subtle.

ionic elk
#

Appears to be stm32 only. And it's quite specific - if the error is between release_displays() and displayio.FourWire, it locks the bus. Other than that it all works ok.

hmmm I have been investigating how RawSample+AudioMixer gives pretty poor results. I discovered that even back when AudioMixer was first merged there were small glitches, but when the "only run background tasks once per ms" code went in it got substantially worse. This is from "before" the background tick optimization, a glitch about 2 samples long

๐Ÿ“Ž MSO1104Z_2020-01-15_09.59.03.png
#

specifying a bigger buffer for AudioMixer tends to hide it, at least from the scope, but there's still a little buzz.

slender iron
#

@gentle bronze does tinyusb work ok with dcache enabled?

raven canopy
#

Does it traverse bit-depths/rates? Off hand, I'd likely say it's IRQ priority related, but it could be the execution cycles of each encoding type. @onyx hinge

@slender iron does DisplayIO currently support screens that need a backlight LED pulled up? Sorry for off topic

slender iron

@indigo wedge no, in circuitpython

indigo wedge
#

ah

#

is that with your flash changes?

slender iron
#

@ionic elk not sure, I don't think so

ionic elk
#

I don't think so either. Worth an issue?

slender iron
#

@indigo wedge yup, also moved stack to dtcm and trying to enable both cpu caches

#

@ionic elk need it for meow:bit? could you just fix it?

ionic elk
#

Maybe, will need a never-reset for digitalIO I guess?

indigo wedge
#

@slender iron yeah i couldn't get that one ram bank working maybe it's related, is this on the evk?

onyx hinge
#

@raven canopy this is on pygamer fwiw but I think any samd51 will behave similar

slender iron
#

@ionic elk there should be one on the backlight pin already

#

@indigo wedge I think I got the flexram setup ok

#

lemme push my changes

gentle bronze
#

@slender iron I have no idea, which issue you are encoutering, I could try to help it out.

onyx hinge
#

default buffer size is 1024, so each half should be 512 bytes, which is 256 samples, or 5.8ms. So there should be plenty of time margin available even if background tasks are only once per ms

slender iron
#

@gentle bronze I broke my latest teensy 4 code and am wondering if the dtcm isn't flushing usb packets before queueing them up

onyx hinge
#

I need to get some better tools to visualize background tasks and dma buffers somehow. I could scope plenty of signals but I don't know how to get them TO my scope

#

(this is monophonic audio, stereo would be 2.9 ms per half buffer)

slender iron
#

@onyx hinge you can twiddle a pin in the background task

#

and you can connect the dma event to a pin as well

ionic elk
#

@slender iron not sure what you mean - there's no backlight definition in DisplayIO, and you can't mark pins as never reset manually, so I'm expecting I'd need to add a new parameter to Fourwire that allows a backlight pin, right?

onyx hinge
#

@slender iron have time to tutor me about that second thing? I have the first in there

slender iron
#

@ionic elk Display manages the backlight, not FourWire

#

@onyx hinge I can later. Now I'm in 3 concurrent conversations. The gist is you add the PORT peripheral as another user to the event generator for the dma signal and then you tell PORT what to do based on event input

onyx hinge
#

@slender iron that's fine, I'll try reading a bit first ๐Ÿ™‚

slender iron
gentle bronze
#

@slender iron to be honest, I am sure either, is there any code I can try

indigo wedge
#

@slender iron i think it might be cause you removed "USB_DEVICES = "CDC,MSC,HID""

#

and like i mentioned, i think we dont have enough EPs to have all 4 classes

#

so i turned off MIDI

slender iron
#

I moved it @indigo wedge because it was the same for all boards

#

oh, maybe i shouldve looked at the whole thing ๐Ÿ˜…

@slender iron if you defined CFG_TUSB_DEBUG = 2 and implement tu_printf to output via UART or SWO, it can be print out useful debugging log

onyx hinge
#

glitch1 to glitch2 is 2.2ms which doesn't mean anything to me right off the bat

@slender iron so you removed the bootloader?

slender iron

@indigo wedge no, I'm just placing the non-bootloader things where it is

@gentle bronze do you have the swo printf handy?

obsidian valley

I'm just not certain what the procedure is to install it and verify if it works. I have tried dragging the .uf2 file into the flashdrive of the board in windows but could not connect to it in mu. And tbh it's been a long time since I used that board and I dont remember what button does what.

@obsidian valley what is the name of the drive? you could try dragging the bin

gentle bronze
slender iron
#

can't remember which file extension the built in debugger takes

#

@gentle bronze thanks!

indigo wedge

it takes bin

#

but if your bin depends on the uf2 bootloader then it wont work

cause it will go to like 0xC000 offset and theres no boot code

yeah, it doens't seem to work with copying bin file to MSD of evk-link

slender iron

Perhaps stating the obvious... I am new to ARM, CP implementation, and even github... I am today seeing this same behavior.
I looked at the systick handler. (I think it does some unneeded things; see below.) I don't see a problem. I didn't dive down into some functions such as one related to the file system. Perhaps those can be moved to software triggered exceptions (maybe using the STIR, if available, for an atomic trigger). Those can then run at a lower priority. From my limited glance, ...

do you power it via the evklink usb or the dc jack ?

@obsidian valley the other usb should show up as a CIRCUITPY drive

indigo wedge

but you have to move a jumper and connect to the 2nd usb @obsidian valley

obsidian valley
#

ok thanks gonna try that

#

ok which jumper to where?

indigo wedge
#

J1 which selects power source should be moved from 1-2 to 3-4 if you want to power from the device USB

otherwise you can have both USBs connected and then i think it's fine to leave it at 1-2

obsidian valley
#

ok I'll try this gotta search for another usb cable thanks @indigo wedge @slender iron

@indigo wedge ah that could be my mistake, that limit apply to lpc18xx, iMX have 8 endpoints for both USBs. I will double check dcd vs datasheet tomorrow.

[adafruit/circuitpython] New comment on issue #2508: time\.sleep\(\) rounds down to next lower millisecond

fwiw, this looks like a classic HAL trade-off. I'm sure Adafruit's main goal is minimizing engineering time to support as much hardware as possible. But like most hardware abstraction layers, the result is often constraining the most powerful hardware to a set of assumptions based on experience with the last powerful hardware.

As someone who focuses on powerful hardware, but also has only limited hours to do far more that people want than can ever be accomplished... I have mixed feelings...

[adafruit/circuitpython] New comment on issue #2508: time\.sleep\(\) rounds down to next lower millisecond

The imprecision here is an intentional decision, as I said when this first came up. The Python code will never have reliable timing. We provide other modules for timing sensitive functions. Sure, it'd be nice if this had sub-millisecond precision but it isn't a priority. We have more reliable alternatives.

So, we'll happily take a PR for this but please don't read too much into this.

@slender iron so what I am seeing is that in audio_dma_background, this new condition + if(event_interrupt_overflow(dma->event_channel)) { is firing pretty much constantly in my test with RawSample + AudioMixer. Additionally, the "glitched" samples occur right when background tasks are being handled, and the glitch data is what SHOULD HAVE been in the stream two glitches before

manic glacierBOT
onyx hinge
#

this is rewinding to BEFORE I reworked the tick handling to fire at most once per ms; this becomes much less clear AFTER ticks were reworked, because up to 1ms or so of data is glitched instead of just a tiny bit

#

@onyx hinge does overflow happen when you do mp3? its possible we don't clear the interrupt

onyx hinge
# 
             continue;
         }
 
+        if(event_interrupt_overflow(dma->event_channel)) {
+            event_overflow_count ++;
+            last_overflow_event_channel = dma->event_channel;
+            last_overflow_dma_channel = dma->dma_channel;
+        }
         bool block_done = event_interrupt_active(dma->event_channel);
         if (!block_done) {
             continue;
``` note that you have to check overflow before interrupt-active because the latter clears the OVF flag
#

I know that it doesn't increment while looping a RawSample without mixer, but I think that's because "single buffer" audio gets a different path. Will test with wav and mp3, jas

I don't think this is how the start of playing a sine wave should look. Specifically, the part in about horizontal div 5 where it goes "Z-Z-Z-Z-Z-Z" while stuck in background tasks. (D0: high = in background tasks. D1: high = dma interrupt request, according to audio_dma_background. D2: high = dma interrupt overflow, according to audio_dma_background.)

@indigo wedge so it's Adafruit's fault after all!

@indigo wedge what else could you possibly use it for ๐Ÿ˜‰

Thanks @marble hornet. I think I was trying to figure out how to get the calculator buttons to be more responsive, but the CircuitPython displayio speed update fixed it.

Please someone give a new micro USB cable to @meager fog ... The red one I see in YouTube video is damaged with the shielding is visible. Thanks.

has anyone else noticed a builtin font error on the nrf52840 feather in 5.0 beta 3 for the letter C ?

@marble hornet wat do you mean?

onyx hinge
#

but manitou we believe in you and think you can submit a PR!

stuck elbow
#

(sadly, I don't have any NRF board that runs CircuitPython, since non-express boards were dropped)

#

I was thinking about making a haxpress board, though

solar whale
#

@stuck elbow I just did a build of the current master and it built the non-express nrf52840 boaeds -- which one(s) do you have?

stuck elbow
#

the Feather nrf52840

solar whale
#

that is an express

stuck elbow
#

is it?

#

it's doesn't have 'express' written on it anywhere, but the firmware does

solar whale
#

yes -- has 2Mbyte Flash chip

stuck elbow
#

ok, I will try it then, thanks

onyx hinge
#

now that you mention it, that's confusing!

#

I hope this patch I'm working on .. works out. Decreases AudioMixer CPU utilization 50% and switches to saturating arithmetic so voices don't get fainter as you mix more. Just waiting on some build testing before I PR it.

solar whale
#

the build is BOARD=feather_nrf52840_express

stuck elbow
#

yeah, but the silkscreen just says feather nrf52840

#

maybe I have an early hardware version

onyx hinge
stuck elbow
#

I wasn't trying the nrf port all this time because I thought it wouldn't work

#

silly me

onyx hinge
#

the flash must be integrated in the RF shielded package?

stuck elbow
#

no, I think there is a tiny flash chip just next to the module

#

@onyx hinge that sounds awesome

#

2 MB of QSPI Flash for storing CircuitPython files

stuck elbow
#

re the patch

onyx hinge
#

it does take +200 bytes or so of flash so I'm worried it might not fit everywhere

marble hornet
#

@stuck elbow i mean the c is shifter up and cut off on the bitmap ?

#

nm, it's my code! hmmmm

what's the best approach to stepping through a mpy file while debugging via stack trace? I hit an error while trying to get my esp32 to connect to a node server and the runtime error is popping up from within one of the mpy files.

I know that I can go to github and pull down the original py file and walk through them that way, but is there an easier way of looking through the mpy files themselves?

#

not that I know of

uneven yarrow
#

hmm, gotcha

stuck elbow
#

00 usually means that there is a problem with the connection, or the esp32 doesn't respond for some other reason

uneven yarrow
#

oh good to know

stuck elbow
#

spi doesn't have any crc or ack, so if there is no connection, you simply just read all 0s

interesting. so I'm using the following url to test:

SERVER_URL = "http://10.10.10.137/"

When I removed the http I got a different error stack

# 
Traceback (most recent call last):
  File "code.py", line 180, in <module>
  File "adafruit_requests.py", line 270, in get
  File "adafruit_requests.py", line 167, in req
ValueError: need more than 1 values to unpack
#

and this is making a request to a simple node/express server I'm running locally

# 
const express = require("express");
const app = express();
const port = 3000;

app.get("/", (req, res) => res.send("Hello World!"));
app.get("/json-test", (req, res) => res.json({ message: "Hello World!" }));

app.listen(port, () => console.log(`Example app listening on port ${port}!`));
#

nothing fancy, nothing special

stuck elbow
#

you need the http, I think

uneven yarrow
#

gotcha

#

hmm, let me try pinging the node server from the controller (haven't tried that yet)

stuck elbow
#

make sure the esp32 has the correct firmware flashed, is correctly connected and is powered

#

(unless it's built-in)

#

I'm sure you've probably got it done already, but just because I caught myself with this the other day: Make sure your sever is visible to other devices on the network

aaaaah
