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.

I am using https://github.com/mcauser/BLACK_F407VE repo. How much free memory does your board show up?
Code: Select all
>>> gc.collect()
>>> gc.mem_free()

[quote=mcauser post_id=22695 time=1508767571 user_id=732] The W25Q16 2MB SPI flash is connected to the SPI(3) bus on the VET6 and ZET6 boards. 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.
