USB Host on STM32F401RE Board(Micropython)

Post by YSN » Fri Feb 11, 2022 5:32 am

I am trying to bring-up the USB Host on my custom board designed with STM32F401RE chip. The USB Device is working fine.
Also have verified the HOST hw by running C code to enable the USB Host.

1. How to add USB Host functionality to Micro python for STM32?
2. I have checked by enabling USE_HOST_MODE, but seems lot of compilation errors. Even tryin to solve them, there is lot of syntax difference in usb.c (Host Initialization code.)
3. Even after making those changes It seems the functions implemented under USE_HOST_MODE are only adding some LED functions not any Host functions are given under usb.c
4. Can some help me to add this USB host feature to micropyhon. (I have seen several posts claiming that this feature is out dated).
But this is required for my project...
5. Kindly share the process or fix for this USB Host feature requirement.
