Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Thanks for the info.

I see that floating point operations are very slow on Black STM32F407VET6. Is this due to micropython, since STM32F407VET6 is a cortex M4.

This script works, with a few modifications: https://github.com/manitou48/pyboard/blob/master/spiflash.py Replace: cs = pyb.Pin('X5') With either: cs = pyb.P...

Re: Black STM32F407VET6 + STM32F407ZET6 dev boards

Hey guys, I got a black STM32F407VET6 board and it is up and running! Thanks to your efforts guys. I see that the board has a flash chip W25Q16. Has anyone tested the flash module? How can I communicate with it? I see that it is wired via SPI bus.
