... "On the F401 I wound up making the files be frozen files." --> I assume this means put uasyncio.py etc into the firmware image (by putting it into ports/stm32/modules or ports/stm32/boards/BOARD/modules depending on your config). This way you don't have to worry about syncing it to your filesys...

I ran into this on the F401 as well (when transferring over UART), and I haven't spent the time to figure out what the underlying problem is. I suspect that characters are being dropped on the UART connection. I'll see if I can look into this next week. This used to work, but it might have somethin...

Hi, I'm trying to copy the uasyncio library to my NUCLEO-F446RE board (MB1136 C-03). I tried to copy the whole folder, I tried to copy single files -everytime I get the error message: $ rshell -b 115200 -p /dev/ttyACM0 cp -r lib /flash Using buffer-size of 32 Connecting to /dev/ttyACM0 (buffer-size ...

... Ok I have not yet ever needed to use 9 bit UART so had to do a bit of googling. Seems 9 bit UART on STM32 works by it stores the 9 bits over 2 bytes. The first bytes stores the bottom 8 bits then the second byte stores the 9th bit plus bits reset values of the UART_DR register so you need to us...

What is wrong with the code?

How can I set the M bit in the UART control register

Ok, I've found the mistake...

Code: Select all

d1 = u1.read(2)

I need to read 2 chars to all 9 bits.

But I still don't see the wakeup bit. How can i do it?

... From the reference manual the STM32F407 supports 9 bit serial by setting the M bit in the UART control register UART 9.JPG I've got my NUCLEO-F446RE board and it's running with MicroPython v1.11-37 now. ...so far so good... What is to do to read the serial connection in 9-bit mode? I tried foll...

@lukesky333 board defs updated. Datasheet added to the /docs folder.

Cool, thank you. I've ordered the board and I let you know, what happened.

Edit: Datasheet received. Will update the board def to match.

Thanks a lot. Could you share the datasheet too?

@lukesky333 I put together these ones for the board: https://github.com/mcauser/MCUDEV_DEVEBOX_F407VGT6 - 1Mbyte flash https://github.com/mcauser/MCUDEV_DEVEBOX_F407VET6 - 512Kbyte flash Both are 100 pin LQFP chips and it looks like larger flash is the main difference. I guessed some of the pin num...

Hi,

I want to buy this board (STM32F407VGT6).

Is it possible to run your version of MicroPython on this board? It seems to be the same like STM32F407VET6, only with more memory.
