I ordered one of the 3.2" TFT's which mate with the "Black STM32F407ZET6" TFT/FSMC pins.
It's using the ILI9341 and XPT2046 resistive touch. Looks like it's similar if not the same board.
Can you give me a link to the TFT display?

@lukesky333 board defs updated. Datasheet added to the /docs folder.
Is it possible for you to adapt the defs for this board (STM32F407ZGT6) too?
Seems to be similar to the other but with RTC, CAM and TFT support...

Thanks!

EDIT: I can provide the schematics for this board, if it helps!

So I added a call to os.sync and that seems to allow things to work properly. I was able to copy a 17K file to my NUCLEO_F446RE board. So please try upgrading to rshell 0.0.26
Yes, with rshell 0.0.26 the problem is fixed. THANKS!!!

Re: [NUCLEO-F446RE] rshell --> timed out or error in transfer to remote

... "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...

Re: [NUCLEO-F446RE] rshell --> timed out or error in transfer to remote

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...

[NUCLEO-F446RE] rshell --> timed out or error in transfer to remote

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 ...

Re: Serial - bit banging

... 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?

Re: Serial - bit banging

... 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...

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