[SOLVED] Error when building Micropython

Hi, I try to build MicroPython for Meowbit now that the source code is released but at the beginning of the compilation (and for any STM boards) on Ubuntu 18.10, I have this error: sudo apt-get install gcc-arm-none-eabi binutils-arm-none-eabi git clone --recurse-submodules https://github.com/KittenB...

Re: question on mpy-cross

Finally got in touch with them using Chinese websites (thanks Google translate....)
Code is available now!

Looks like the meowbit is quite new, maybe they just haven't gotten around to releasing their repo yet. Might be worth emailing them directly?
I did last week, I tried Slack, their support email... no answer :( Weird company but cool toy :)

Re: question on mpy-cross

Dave... I just saw that you're the guy behind the Brainpad micropython sourcecode.... how much the meowbit is different from the brainpad arcace ?

Re: question on mpy-cross

Hi Jimmo, Yes you're right... that's not a baremetal micropython firmware, thanks for forcing me to re-arrange my brains :) So yes I would need to generate a uf2 compatible with their loader.... pretty different than generating a micropython firmware. I hope they will publish the source code of thei...

Re: question on mpy-cross

Thanks Dave, that helps, I was looking at which micropython/ports/stm32/boards/ templates I could use. The NUCLEO_F401RE looks very similar. Should be enough for mpy-cross. A little unrelated question, if I would like to build my own firmware and use the NUCLEO_F401RE as a base, do you think: 1.I ca...

Re: [Neowbit / STM32F401RET6] Simulating VBL interrupt ?

Oh... thanks for the tip... MicroPython interrupt handlers are very restrictive.... I guess not way to update the TFT framebuffer by reading data on the SD without creating objects and appending to lists... Maybe I need a kind of shared buffer, read by the IRQ handler, filled by another mean... Goin...

[SOLVED][Neowbit / STM32F401RET6] Simulating VBL interrupt ?

Hi, The Neowbit has a 160 x 128 TFT color screen usable thru the pyb library (pyb.SCREEN()) and a unique method: show(fb, mode). I'm not sure what type of TFT this is and as I don't have the source code of the SCREEN class that's pretty complicated to understand how it works behind the scene. https:...
