usb problem

[eao]

Hello, I have a confusion. Now I want to connect two identical development boards through USB for data interaction. I checked the example of USB, but I didn't see any example of communication between MCUs. Which one can I refer to? Modified example. The development board is RT1170, Thank you.

Hi @eao ,

Do you mean you want to connect two RT1170 board with USB? That is one board act as a master, the other act as a slave. You can download usb_device_cdc_vcom project to one board and usb_host_cdc to the other. These two project can be found in RT1170 SDK.

Regards,

Thanks for the reply, it is probably this one, one as the master and one as the slave. I read the examples in the SDK and found that there is a difference between dev_cdc_vcom and dev_cdc_vcom_lite? thanks
