Re: How to get uint(uint16_t) from arg?

Can you explain what you mean in more detail? Or perhaps an example showing the problem you're seeing? You should just be able to write int a = mp_obj_get_int(args[5]); uint16_t b = a; If a is in the range [0, 65535] then b will have the same value. If a is negative or greater than 65535 then you'l...

Re: How to expand the size of spiflash?

@turoksama it looks like you're using the spiflash #defines, but setting qspiflash pins. e.g. MICROPY_HW_SPIFLASH_IO0 isn't actually used by anything (unless you've also written more code not posted here to configure the soft qpsi?) Have a look at ports/stm32/boards/STM32F769DISC/mpconfigboard.h to...

Re: How to expand the size of spiflash?

Well, it is stm32 platform.
So, why the capacity setting is not affective? Are there any tricks hide somewhere?

Re: How to expand the size of spiflash?

Hi,
A custom board designed by myself, STM32F411RET6 CPU.
Mostly looks like PYBV10, but embeded an spiflash of 16MB capacity(use softqspi).
Due to the size of firmware(add some custom libs), I have to use that spiflash for USB storage instead of internal flash.

How to expand the size of spiflash?

Hi there, I built a custom stm32f411 board recently, embeded with a 16MB spiflash(Do not use internal flash for storage). When loaded the firmware, it's max size is 2MB, not 16MB, and something wrong with file read or write. I've look up over all codes about spiflash in Micropython but with no luck....

Yep, I found it too.
I'll look into that.
Thanks!

Where to find any docs about upy FULL FEATURE PORTING guides?

Hi there, I tried to build upy recently, it is really great! Amazing work. After serial days hard work, I still have little idea about porting to a custom board, there are lots of boards can be refrenced though. Because not all of these boards support a particular feature, and don't know what to do ...
