What coworkers and I did a few times is just to solder all pads without taking care of possible interconnections between adjacent pads. And then to remove the excessive solder with solder wick. Sounds strange, but worked. I second this suggestion, which in my experience works very well. I've done s...

I successfully compiled micropython with ulab for the pyboard-D (SF6), but I can't seem to do the same for the unix port. This is on a Mac with macOS 10.13.6 with the latest XCode tools. Here is my build script: git clone https://github.com/micropython/micropython.git git clone https://github.com/v9...

In any case, if you can compile a working piece of firmware with the latest source as @jimmo suggested, would you mind reporting back here? If it is still not working, then I would be interested in finding out where the problem lies. I did compile a working version based on micropython 1.11 (6f75c4...

I would suggest changing all occurrences of "float" to "mp_float_t", that will allow it to compile for all targets with the FP precision supported/configured by the target. Done. I have also uploaded compiled firmware for pybv11, and pybd_sf6 to https://github.com/v923z/micropython-ulab/releases. I...

Done. I have also uploaded compiled firmware for pybv11, and pybd_sf6 to https://github.com/v923z/micropython-ulab/releases. Thanks again! I just tried on pybd_sf6 and everything seems to work fine, except that: - By default I can connect to the board using rshell. - But after I modify boot.py to i...

It would be good to know if the fix is down to the baudrate change or separating initialisation from instantiation. Just checked and the single-line declaration also works. This must be linked to the approximate baudrate (see http://docs.micropython.org/en/v1.9.3/pyboard/library/pyb.SPI.html ). Ano...

I am trying to compile ulab for the PYBD_SF6 on macOS following instructions found at https://github.com/v923z/micropython-ulab/blob/master/docs/source/ulab.rst . When I run make BOARD=PYBD_SF6 CROSS_COMPILE=/usr/local/bin/arm-none-eabi- I get the following error: make: *** No rule to make target `l...

Replying to my own thread: I was able to fix the issue by replacing, in the ws2812 module,
by

The example code from <https://github.com/JanBednarik/micropython-ws2812> produces the expected result on a pyboard 1.1, but the same code on my pyboard-D lights up the whole LED strip in white, and I'm unable to change any LED. SPI 1 and 2 behave in exactly the same way. Has someone noticed this be...

Dear all,

Sorry if this is a stupid/lazy question, but I wasn't able to figure it out myself: is it possible to edit or upload code wirelessly on a pyboard-D, using webREPL or some other method? If so, is there a tutorial somewhere?

Thanks in advance.
