Posted on December 18, 2017 at 15:17Hello.,
I am working with STM32F7 MCU in custom board, Actually it has two onboard MCU(both are STM32F7 microcontroller), Now my first task is to establish USB communication between two MCU's . I tried by configuring one MCU as host and another as device (USB_CDC class), but I couldn't able get any progress in this . The same configuration I tried between two Nucleo board in that I can send/receive data , But in this board I am facing the issue.
Can Anybody suggest how to start and which example I need to use , Also I need some clarity on Which USB class is better to communicate two MCU's .
In our board USB_DP & USB_DM pins of one MCU are directly connected USB_DP & USB_DM of another MCU's, and we are not using VBUS pins.
#usb #usb_cdc #stm32-f7 #usb_host #usb_device
