as well, LCDs may have gamma correction registers (ST7789 does)

#

but just what goes in those registers is 🤯 😰

tiny peak
#

I ask because I've started working on a gamma calibration thing for Feather TFT. (compare checkerboard dither to solid colors, etc). When I tried initializing my ST7789 with the four different built in gamma curves (2.2 default, 1.8, 2.5, and 1.0), the default 2.2 gamma seems the closest.

onyx hinge
tiny peak
#

What I found with my DIY calibration tool is that the ST7789 with 2.2 gamma preset is fairly close to the the luma response of a color managed sRGB computer monitor, but not quite (stretched a bit). I'm wondering if there's some 24-bit RGB to 5/6 bit RGB565 happening with >>3 and >>2 somewhere, and if maybe that's skewing the curve (vs mapping 8-bit 2.2 gamma to 16-bit linear, scaling that, then mapping back to 5 or 6-bit 2.2 gamma)

#

thanks for the suggestions, I'll check out those links

onyx hinge
#

Bitmapfilter is all rgb565 so if it's a problem with 888 to 565 conversion that's not gonna help

tiny peak
#

ah, okay... what I'm ultimately hoping for is to be able to have sRGB PNG files displayed through displayio and actually look pretty reasonable. At the moment, it's in the ballpark, but still kinda contrasty and overexposed, with some color shifting.

#

Thanks for the input. I've got some trails to follow, but I wanted to make sure I'm not overlooking previous work.

@lone axle I am working on the library, and pylint is now complaining about "too many arguments" for quite a few of its functions. I disagree. What's your opinion: should I disable in .pre-commit-config.yaml or should i disable for each such function? What's our usual? I looked in the bundle and I only found one library (esp32spi) that disables in .pre-commit-config.yaml.

#

maybe in the code, so pylint doesn't complain even without using pre-commit

#

and should I do it for each function, or just at the top of the file?

stuck elbow
#

or maybe you could change the max number of arguments for pylint

tulip sleet
#

good point, in .pylintrc

#

hmm, we don't do that anywhere, surprisingly

stuck elbow
#

hmm, looks like you could work around it by using keyword arguments

tulip sleet
#

max-args=5 right now, so that's any kind of args

ah, sorry

# tulip sleet <@382939733107408897> I am working on the library, and pylint is now complaining...

I am a bit late getting back to this, I think most typical is individual pylint exceptions on functions that have too many arguments. However I would also say that I feel 5 arguments is a fairly low limit, and I would have no problem with increasing that a bit in the overrall config to try to lessen the cases where individual ignores are needed.

I'm not entirely sure where the limit of 5 came from, if that is mostly arbitrary or actually enshrined somewhere as a more official "best practice"

tulip sleet
stuck elbow
#

as far as I am familiar with python style guides, it's arbitrary

tulip sleet

tbf I find most of pylint defaults to be too restrictive

I think they are meant to show off the feature to new users, who are then expected to immediately raise them

I investigated this but didn't find a solution

[adafruit/circuitpython] New comment on issue #9726: Pico-W: Setting wifi.radio.dns sends device into safe-mode

I will try your patch and report back.

It would be useful to know if setting the ipv4_dns property, which does have to be an IPV4Address, is also crashing; and it might serve as a workaround for you in your code.

Currently I am using wifi.radio.set_ipv4_address() which takes IPV4Address arguments. That works fine. I will test the setter too. The main reason I actually tried wifi.radio.dns was that I wanted to set more than one DNS, which is not supported as I learned.

I was taking a look over this cp.org PR to add this cezerio esp32c6 dev device https://github.com/adafruit/circuitpython-org/pull/1491. The link provided there (https://cezerio.com/cezerio_dev_esp32c6) looks like a normal albeit somewhat minimal product page, but it's lacking any clear picture that shows the device. Also the "buy with paypal" button just links back to the page you're already on. If you click back out to the home page of that cezerio.com website there is a row of product listings, one of them lists that device name and does show a picture (attached), but that appears to be a different device by a different company. A quick search on the image led to https://deneyapkart.org/en which does seem to be the MCU that is depicted, and it claims a different processor (Tensillica LX6). The row of products on that cezerio home page also seems to randomly include some clothing based placeholders that are unrelated to anything else on the site.

Perhaps this is not a big deal, just a brand new device with a website containing placeholder images and product listings for a device that is not quite ready to sell yet?

I wanted to mention though and ask if there are any guidelines around how "done" and accurate the pages linked from circuitpython.org need to be? Is it okay if they don't seem to show the actual hardware? If there is a link in the description labeled "purchase" but it goes to a page that doesn't seem to allow purchasing is that an issue?

[adafruit/circuitpython] Issue opened: #9729 PixelBuf: TM1814 needs to dynamically modify the header bytes to set brightness

TM1814 LED strips use an overall strip brightness value that is transmitted as the first 64 bits of data.

To allow the brightness to be dynamically updated, these 8 bytes of the header need to be modifiable.

However, the "transmit buffer" is a read-only object and is only intended to be available inside the _transmit method, so there appears to be no way to update the header (or, for that matter, trailer) values.

[adafruit/circuitpython] New comment on issue #9729: PixelBuf: TM1814 needs to dynamically modify the header bytes to set brightness

@jepler I think it was to save memory by not allocating the post-brightness buffer until a non-1.0 brightness was set.

I think an option 6 where transmit is given a bytearray instead of a bytes object may be best. That way the transmit function can mutate it (to set brightness) before transmitting it. The buffer still stays "internal" then too. The subclass will want to override the brightness property so that the internal post-brightness buffer is never allocated.

# onyx hinge <@382939733107408897> If you have the time I made a library today and could use ...

I try to delete the extra copyright lines that end up in the examples like https://github.com/adafruit/Adafruit_CircuitPython_tm1814/blob/main/examples/tm1814_led_animation.py#L1. I don't think they actually upset reuse, but my understanding is that the earlier copyright attributed to Scott is really meant to apply to the template file inside of the cookiecutter. Once it's in a new library and has real code for the library added to I think having only the newer copyright for when the library was created and the code added is sufficient.

Though I don't know if this is documented anywhere, and in any case isn't really a huge problem AFAIK.

Everything else that you've got is looking good to me.

OK I zapped those lines

Thank you!

Merged now, and made a new release for it.

@lone axle by the way, I tried making a PR from my fork of the Bundle repo, and it failed pre-commit, looking for pkg_resources.

it was having trouble with reuse

I tried updating to the latest pre-commit actions, but it didn't help. My pip modules are very up to date

#

i am constantly running into this with pre-commit. Somehow I get it to work eventually in other repos, but it's really confusing.

lone axle
#

Ahh, yeah I see that locally as well on a fresh clone

tulip sleet
#

we saw this with pylint 2.x.x. Updating it fixed things. THe pre-commit author is constantly saying to update virtualenv, but that's not the fix

#

and he's very curt about this kind of error

lone axle
#

Maybe reuse needs to be a newer version

tulip sleet
#

I just upgraded to 4.0.3 locally, still, the same thing

lone axle
#

I will try 4.0.3 too

tulip sleet
#

it was 3.0.2, I can try 3.0.1

#

no diff

lone axle
#

Ahh, 4.0.3 exists as well and is the latest release. I did try that one and it runs for me as well.

#

are you in py3.12 environment?

#

yes...

in a venv

#

hmm pre-commit was at 3.8.0, but 4.0.1 is availaable

#

ah, it worked!!

lone axle
#

weird, it looks like all the same versions as me. Yeah there is a newer pre-commit I'll try that as well, I am on 3.8.0 now as well.

$ pip show pre-commit
Name: pre-commit
Version: 3.8.0
#

4.0.1 runs for me as well.

tulip sleet
#

i am baffled, but it's back to working

#

ah, no, broke again

#

i did pre-commit clean and the pre-commit install to get a fresh pre-commit setup.

#

so it was breaking some of the time for you, or not at all?

lone axle
tulip sleet
#

thanks, I will try some more things later. The last this broke, the cause was something seemingly unrelated, but I can't remember what that was now. :/

lone axle
#

I believe every time that I have seen ModuleNotFoundError: No module named 'pkg_resources' it's been related to having older versions of libraries trying to run under python 3.12.

tulip sleet
#

i'll try updating everything, which is not a single option to pip3

lone axle
#

it looks like the bundle actions are set to py3.10 https://github.com/adafruit/Adafruit_CircuitPython_Bundle/blob/main/.github/workflows/build.yml#L24 which is why the same error hasn't occurred in the actions runs yet. But it would be good to go ahead and update to a newer version of reuse in the bundle repo, at least up to 3.0.1 to match the libraries, or even 4.0.3 to just bring it up to the current latest. Then we shouldn't have that issue when we update the actions container python version.

There is a silabs port, but maybe not for the chips you want?
Nordic has moved to zephyr from SoftDevice for its more recent chips. This requires a complete rewrite on our part of the chip-specific code, including BLE. For a while zephyr wasn't suitable, because it didn't allow run-time assignment of pins to functionality, which you can do in CircuitPython. This has changed but updating the nordic/ port to zephyr is not a high priority.

tulip sleet
#

@lone axle I had to fix some things about the BLE library because it was broken after a recent PR. I merged the changes without review in case someone wanted to use main or a release was made accidentally. (I did test my changes!)

And I ran into max-args again. Rather than put disable=too-many-arguments in about 10 places, I changed max-arg= in the .pylintrc. This seemed like a more reasonable solution in this case, because the library is pervasively full of longer arg lists.

Do circuitpython-org listings have to be 1-to-1 with boards added to the core circuitpython repo? Or can some be doubled up?

The seeed_xiao_esp32_s3_sense board was added to the core here https://github.com/adafruit/circuitpython/pull/9530/files and has been added to circtuitpython.org already.

My understanding is that this device is essentially a seeed_xiao_esp32s3 MCU and the "sense" indicates the addition of the camera module.

We don't have a board in the core for the standard seeed_xiao_esp32s3, only the "sense" one.

Is it neccessary to add that plain board to the core in order to add the plain one to circuitpython.org? or could a new listing in .org for the plain one just re-use the same board_id in order to be linked to the existing board definition that is technically for "sense" but should work for both if I understand.

In this particular case, I think it's an oversight that there isn't a board for the plain seeed_xiao_esp32s3 (I remember someone else raising that), and it makes sense to have two boards. There are cases where there is a very minor different a few Adafruit boards that may or may not have a BME280, or the PyBadge LC/non-LC. But this is a pretty different board, with dedicated pins for the camera, and some different compile settings.

@tulip sleet that's weird. From my limited networking experience it's pretty common to use that as a "wildcard address" (probably not a technical term) when creating a server.

#

I'd look at the code converting strings to IP addresses (getaddrinfo), which I recently tromped on for ipv6 stuff

tulip sleet
#

right -- it was causing a safe mode crash on the C3. I also tested on S3 and it wasn't crashing, but I think it wasn't working either.

onyx hinge
#

like, does ping("0.0.0.0") or connect crash in the same way?

#

(it probably wouldn't WORK if nothing's listening, but it shouldn't crash)

tulip sleet
#

I'll try it with 9.1.4, which does not have your changes, I think

Hi @slender iron , I managed to catch one of those ESP32-P4_EV boards. Could you please give me any hint on how to flash CPY .bin to it? I tried webflasher, but that one does not know the board. Then I tried flash download tool, but I´m probably flashing it to the wrong address so it is not working either. Many thanks in advance.

[adafruit/circuitpython] New comment on issue #9728: Can't build mpy-cross: "CircuitPython must be built from a git clone with tags"

At some point I gave up and installed WSL.

The problem is that the machine I was trying to build everything on didn't have WSL. In short, I think we should just rely on WSL and not expect to be able to build anything on Windows. Given that the rest of the build process didn't go very smoothly either, I don't think it can be beaten without Linux.

In the end, I was able to build everything I wanted using WSL. I'm trying to connect two displays to one device as shown in this article: https...

The W55RP20 is a SiP project that integrates the RP2040 and W5500 in one chip. Internally, the dies are connected via general GPIO pins, not the typical SPI pins. As a result, a PIO program is needed to configure these pins for SPI communication.

What are the thoughts around the Xiao S3 (non-sense) device from: https://github.com/adafruit/circuitpython-org/pull/1500 that device isn't included in the core currently, based on conversation here it seems there has been some delay / trouble getting a PID for it in order to be added to the core.

Would we want to hold out for a PID and if / when one is assigned then it can be added to both the core and the .org listing at the same time?

Or would we want to treat it as an alias in the .org listing and have it match up to the seeed_xiao_esp32_s3_sense which is in the core now?

AFAIK the devices are basically the same except for the the connector that the camera add-on plugs in to is omitted on the non-sense version, it's position on the board is there, just no connector soldered.

I found a few different "device finder" utilities that let you search by VID / PID, and this list which seems to be used by linux http://www.linux-usb.org/usb.ids. In all the places I've found so far seeed is listed as VID 0x2886 but the only PID listed for them is 0x0002 for the Seeeduino Lite.

I know they have more devices than that, but it seems their PIDs don't or haven't yet propogated into the data that these sites are pulling from.

@slender iron the STACK_GUARD being enabled depends on SOC_ASSIST_DEBUG_SUPPORTED being defined, which is also true on ESP-C2, C5, P4. My inclination is therefor to turn it off everywhere, since it might also be causing problems elsewhere that just haven't been reported yet. Would you disagree with that?

I've changed this PR to a draft, because I am currently contemplating the possibility of implementing multiple synthio.Biquad objects on a single audiofilters.Filter effect. Doing so would require that the synthio.Biquad objects generated by the newly added methods (ie: audiofilters.Filter.low_pass_filter) would not automatically update the audiofilters.Filter.filter property.

@fleet hollow hey I appreciate the DM but I'd prefer to have technical discussions on the open channels.

I'm not against adding other filter types that fit within the biquad "mold". As much as anything, the current set was seen as a minimum viable filter set, and roughly since then I haven't been allocated (& haven't made a good case for) more work in that area.

I mentioned making biquad filters settable (including as you noted from other blocks) over in #live-broadcast-chat . I sorta think it would be better to work on that first and then add more filter types second.

The "way to calculate" I mentioned I wrote up at https://emergent.unpythonic.net/01717331483 -- you can evaluate "one and a half" 5th degree polynomials to get an adequate approximation of sin(x) AND cos(x) for the same angle x, which is quite likely to be fast enough to allow recalculating filter coefficients every N samples just like LFOs are now.

# 
    mp_float_t s = MICROPY_FLOAT_C_FUN(sin)(w0);
    mp_float_t c = MICROPY_FLOAT_C_FUN(cos)(w0);
``` as you probably know most of the biquad routines start by calculating sin & cos of "w0", which is related to the characteristic frequency of the filter
#

now a GOOD property of the current biquad is.. you can construct them from Python code, synthio.Biquad is a constructable tuple-like object with 5 fields, so you can write your own filter styles in Python code. that would break if we made biquad an object with kind, w0, and Q fields that take block inputs so it's an incompatible change..

fleet hollow
onyx hinge
#

so this would be a "circuitpython 10" thing. I don't think many people are probably creating biquads from their 5 coefficients but i also wouldn't rule it out. Having biquads that could be manipulated by LFOs would be far preferable. imo.

#

(or you have two kinds of biquad? idk)

fleet hollow
#

I'm not 100% familiar with the structure of synthio.BlockInput, but based on synthio.Math, I would think it's possible to layer BlockInputs. Biquad could be updated so that each coefficient is capable of being a BlockInput and then the filter types themselves could be classes which extend Biquad.

onyx hinge
#

anyway I am gonna sign off for the evening. Thanks for taking the time to chat a bit.

if you want to chat at greater length we can always have an audio or video chat here on the adafruit discord.

Hey guys
I’ve been playing with a Raspberry Pico 2 and Pimoroni Pico Plus 2 and have come across the same issue with both.

After a while (in some cases a few days) the devices stop mounting

I’m about to mount into boot mode without issue, but the non-boot-mode stops mounting.

I've tried the flashnuke, and reinstalling CPY - the mount will appear for a short while...and then drop again (and stop mounting). I have this issue on both Mac and Windows....what am i doing wrong!?

Here a sine wave midi note 72 is played normally, then with a low pass filter that sweeps up, then with a high pass filter that sweeps up, and finally with a band pass filter that sweeps up. I'll be making a PR later this morning I hope. I'll let one of you who knows the new audio filter stuff wire it in there, it's only wired to synthio so far.

@AirplanegoBrr Showing anger doesn't make things happen. Your point about the documentation being ambiguous is taken, and I've opened a PR for that: #9758.

    size_t size = (heap_top - heap_bottom) * sizeof(uint32_t);
    _heap = tlsf_create_with_pool(heap_bottom, size, 64 * 1024 * 1024);

        _psram_pool = tlsf_add_pool(_heap, (void *)0x11000004, _psram_size - 4);

why are you starting the PSRAM pool at +4 past the beginning of PSRAM? It's not clear to me yet whether tlsf_add_pool() is expecting something to be zero'd

[adafruit/circuitpython] New comment on pull request #9756: synthio: Add a form of biquad filter that uses BlockInputs

I took your suggestion to rename FilterType to FilterMode. I also added the notch filter from https://webaudio.github.io/Audio-EQ-Cookbook/audio-eq-cookbook.html.

shelf & peaking don't seem to be useful until it's possible to have multiple filters (and/or their application is beyond my knowledge); they also pose a problem in that they have an additional "A" parameter related to overall gain. Presumably all BlockBiquads would have an "A" or "gain" property that would be ignored if it is not...

[adafruit/circuitpython] New comment on issue #7693: Feature request: Add Bluetooth support for Pico W

I think part of the problem is that the Pico-W is not just another "single board". It is a board that has created a whole ecosystem. It is used in many educational projects. It is one of the few boards that work on two batteries with voltages down to 1.8V. Some manufacturers only produce RPxxxx based boards (Pimoroni is a prominent example). And like here in Germany, it is sometimes hard to buy quality boards from Adafruit, so if you want ESP32 boards, you have to order in China and the qua...

[adafruit/circuitpython] New comment on issue #7693: Feature request: Add Bluetooth support for Pico W

just to add to this.
I think it is very useful to have a board that does what the pico does in that it is available in normal and wireless versions and it saves cost.
This does mean that if someone buys the pico W then they want the wireless capability.
Also it is useful to have a good all-round board with ON BOARD wifi instead of having to use a extra wifi board that adds to cost and complexity.
And the pico is quite popular so there would be many users that would use BLE on it if it was...

@bato3 the list of built-in modules on the downloads page now links to the documentation page for each module.

are there any tools that one could use to modify a CP UF2 file to edit the filesystem on the CIRCUITPY drive? My goal is to be able to pre-install several libraries, boot.py, code.py on the target device, along with flashing the device with CP.

Currently I have a two step process that goes like

  1. Put board into UF2 bootrom, copy over CP UF2
  2. Wait for CIRCUITPY to come up, copy over libraries and code
#

I'd like to be able to just point folks at the current version of a UF2 that includes the latest release of code

this doesn't work on boards where CIRCUITPY is in a separate external flash chip, because the bootloader doesn't know anything about it.

[adafruit/circuitpython] Issue opened: #9765 Exception for I2C NACK handling/signalling

Some I2C devices, e.g. the newer Sensirion sensors, use NACK for specific signaling. For instance, upon an I2C write, the CRC byte is NACKed when incorrect. Or an I2C read header is NACKed when no data is available (yet). Therefore, it would be helpful, if a specific exception would be raised that would further indicate the byte of the transmission that got NACKed. Currently, there's a generic OSError No5 that indicates a failure of the I2C transmission.

"Pitch" transposition on an audio sample without modifying the playback speed is not something that is currently available. Technically, you could feed sample data into synthio.Note, do some math to work out the frequency to get normal playback, and then modify the bend property to change the "pitch".

I think what a lot of people want (including myself) is the ability to change the playback rate of a sample, independent of the sample rate. You can do this if you don't use AudioMixer, but then you incur the clicks/pops of starting/stopping the audio system or USB accesses.

I've come across a lot of code like this:

When I try to run circup from a terminal window: circup :circup --host 192.168.5.130 --password JBPASS install --auto

# serene schooner When I try to run circup from a terminal window: circup :circup --host 192.168.5...

OK it's starting to make sense how you could see such a message: circup (running on your computer) uses requests, requests uses urllib3, and urllib3 requires openssl "1.1.1+".

Your error message shows that your Python version installed on your computer is very old (3.7). You will need to use a newer version of Python to resolve this problem.

I do not know offhand the correct way to install or update python on macos-based computers.

tulip sleet
#

you don't have to use circup. You can just download and unzip the bundles and copy the library files or directories over individually.

serene schooner
#

Thats what kills me. I did an install from the Python site and it's supposed to be 3.9.14 , I think but yet I'm seeing all these Python 3.7 messages which also probably means I'm going to have to save all my texts of command I've written and restart the Mac

onyx hinge
#

@tulip sleet since it's a wifi board I think just unzipping is not an option here

tulip sleet
onyx hinge
#

Yeah I think you need to resolve why python 3.7 is being used. your messages indicate you're using a "virtual environment" or "venv"; a venv is tied to a specific Python version, so you'll want to recreate your virutal envronment making sure it is created by the right Python version

tulip sleet
#

it's a lot easier to develop on a board that has a CIRCUITPY drive, though you may not want to get a new board

serene schooner
#

My iMac is Ventura 13.6.4 and my MacBook Air is Sonoma 14.2.1 (Thanks Apple for auto updating me to a system which kills my music software)

onyx hinge
#

(assuming that it's compatible, again I don't know much about macos)

tulip sleet
#

if you are going to install python on macos, I'd recommend using brew, instead of installing it standalone. It will handle the PATH stuff better.

onyx hinge
#

I'd listen to danh about that

serene schooner
#

I just did the update and it might have been 3.13

tulip sleet
#

the macbook air should Python 3.9, I think

serene schooner
#

Is there a way to restart Python without restarting the Mac

tulip sleet
#

it's a question of finding out where it was installed, setting up a venv using that Python, and then installing circup. brew will take care of some of that

#

you don't restart python, but you do need it on your path, or know hwere it was installed

serene schooner
#

Just to let you folks know how clueless I am about command line AND Python, what the heck is brew?

tulip sleet
#

it's what developers and other folks use to install third-party command-line software and other software on macOS cleanly

serene schooner
#

setting up a venv???? command line clueless......

tulip sleet
#

that's what I mean, you don't necessarily want to go there

#

do you have any other non-mac computers, even a raspberry pi?

#

i think you will not get these errors with the 3.9 Python on Sonoma. That should be new enough.

serene schooner
#

not that I use. a couple of old windows laptops I haven't used in decades. A dozen or so Arduino boards, but thats it

#

installing brew on my imac as we speak

#

both macs have brew and now when I do a python3 command I get 3.13 on the iMac and the MacBook Air

I want to move my Bluetooth Keyboard code from a ITSYBITSY NRF52840 to a ESP32S3 board and to use BLE.

I found in Github something about "Add ESP BLE GATT server support
#9222" but I am unable to find a small working BLE HID KEYBOARD sample.

Are there samples out there which can run on a ESP32S3 and CP 9?

Can anyone point me to a CircuitPython 9.2.0 sample?

PS: What I found is a sample for MicroPython

#

Something similar like this for CP would be great.

I currently have a Feather S3 board.

I've decided to have the new methods simply return the synthio.Biquad object rather than update the filter property, because that will work better for future updates to this class (support for multiple biquads).

I've also added a deprecation notice in correspondence with https://github.com/adafruit/circuitpython/pull/9756. However, this does cause an error in the docs because that PR hasn't been merged yet and synthio.BlockBiquad doesn't exist in this branch.

@lone axle dunno if you're continuing to iterate on circuitpython.org but I like the little badge style "features" and wondered if you considered using a similar style for built-in modules and frozen modules. This would have the side effect of fixing the "space comma space" and "erroneous trailing space" afflicting the built in modules list.

one thing that would be important is whether it'll still invite clicking to go to the docs (not that I know whether many people reach the docs that way, but I do consider it a valuable feature)

Is there any easy way to tell a neopixel to turn on to white and have it sort out automatically to use (255,255,255) on a standard RGB, or (0,0,0,255) on a RGBW? setting it to (255,255,255) if self.pixel_object.bpp == 3 else (0,0,0,255) works but feels kind of verbose.

Oh, interesting. I'll have to try to do some more specific testing. Though I'm not sure if I have any that have white channel. I was working off of feedback from someone running code that I helped them write and ended up adding that ternary, I can't recall if there was a specific error that led me to adding it though.

Dan,

I had to change your 'smaller' code example as below.
go_dev_mode now has to be True or False.
The line starting with mode (#2) results in 'mode' being set to True or False. So in the 'if' line go_dev_mode must be True or False. I could not get it to work when go_dev_mode was set to 0x00 or 0xff.

`
go_dev_mode = True
mode = (microcontroller.nvm[0] == 0xff)
if mode != go_dev_mode:
microcontroller.nvm[0] = 0xff if go_dev_mode else 0x00

[adafruit/circuitpython] New comment on issue #7322: audio glitches when I2C or SPI display is updated

A confusing version of this is if you had previous code which used the display and then you switch to the new synthio code but CircuitPython holds the display active. I had this on an EDU PICO recently. This would be even worse if the display was no longer connected losing the visual cue!

I see the code in this issue uses displayio.release_displays() but most people won't include that in code that was never intended to use a display.

We can set some of them lower than 13 if necessary on a per-port basis. At least esp32 and arm ports all use 13 from what I could see.

I recently lost some time because CircuitPython for rp2040 built with gcc 10 just didn't work (wouldn't boot). It seems preferable to stop the build if it's an older version of GCC than the one we use in CI, unless we specifically test some older versions.

[adafruit/circuitpython] Issue opened: #9780 Duty cycle modulation for synthio Note object (AKA PWM for commonly used on square wave oscillators)

A common modulation techniques for synthesizers is modulation of the duty cycle on one or more oscillators. A simple example of a triangle wave LFO modulating a square or approximate square wave. It would be useful to have some efficient way of varying the duty cycle on at least a square wave and having that controlled by the usual myriad of synthio options.

Workarounds

I've been doing this by reading the value from an LFO and ma...

NOTE: im not sure im looking at the right (version of the) file (line numbers on your error message dont match with what im seeing in github)

on a quick glance over the code, seems like the variables get passed (their addresses) into flash_get_sector_info which populates their value. but the compiler might not be smart enough to notice all of that "machinery"

seems "safe" initializing, adding = 0 to the variable declarations, to silence the error.... values will later get overwritten

The lower-level flash-write code in supervisor/internal_flash.c does cache flushing when PSRAM is in use. Some of that code is duplicated in microcontroller.nvm, but it didn't have the cache flushing.

I have looked at the Seeed Xiao ESP32S3 basic board and the Sense board in more detail. The difference, as @deshipu noted, is that the Sense has the camera add on board.

There is a special very dense multi-pin connector on the base board for connecting the camera board. Because of that, the pins used for the camera are otherwise inaccessible.

When I wrote the PR my feeling was that it's good to generate valid JSON from arbitrary objects when possible, but I agree with the argument that you shouldn't serialize it when it can't be properly deserialized.

I really dislike knowingly creating invalid JSON; that just feels like a bad practice.

I'm seeing the readthedocs CI build fail on my port PR for MAX32690 (https://github.com/adafruit/circuitpython/pull/9667). I think it may be failing because my docs scripts (e.g. conf.py for Sphinx) are out of sync with the up-to-date CircuitPython main branch. In particular the versions I have generates a warning due to using get_html_theme_path which is deprecated.

Seems like the best solution would be to sync my fork & rebase the port/max32690 branch from the up-to-date main branch to get those files up-to-date. The CONTRIBUTING.md seemed to express a desire for not rebasing. What's the preferred method to resolve this? I'll leave a comment on the PR reflecting the answer but just want to verify before doing something that makes someone's life harder 😅

Say you want to have a range of 1% to 99% duty cycle, you could generate a square wave array (bigger will provide better detail as you get closer to 99%) to load into waveform. If your array is of 1024 elements, you could get 99% duty cycle with a value of ...

Thanks, I'd forgotten about the waveform start/end offsets. This does seem to be a good way to accomplish modulating the duty cycle and I agree that the idea of having them act as BlockInputs is interesting.

I don't think modifying a property such as waveform or waveform_loop_end from Python code can give an effective update rate of more than the number of samples generated at one go, because Python code is not being evaluated while samples are being calculated.

In the example I shared originally, the duty cycle does not change linearly and produces an output that is not the best demonstration of controlling a square wave duty cycle through synthio.

I've modified the example to demonstrate controlling duty cycle with LFO in a linear fashion. This uses a "window" technique by controlling both waveform_loop_start and waveform_loop_end in tandem. The loop "window" should always have a size of SIZE // 2 (this would be affected by any drift betwe...

The problem is that there are many, many print routines for native objects, and ideally they would all raise an exception when asked to print to json. So this is just one among many. Instead of taking up code space, we could consider a more general solution that provides for JSON printing for the few objects that work (ints, floats, bools, strings, dicts, sequences), and automatically forbids other things.

I kept the conditions mostly the same, but it's now handled within the calls to synthio_block_slot_get_limited. I've updated the docstrings to remove references to ValueError since that is no longer applicable. The major difference is that the code no longer checks the loop_start/loop_end values to see if they are outside the range and instead just clamps them to the valid range. I've removed portions of the docstrings which mentioned this.
