Dear. All.

I have one problem.

until now, I used well to connect with USB OTG interface.

I've been using USB C to USB A cable. and then, we have no problem.

but, I found a problem at using USB C to USB C connectivity.

the PC & my MP151C board didn't recognize each other.

I'll use my device for slave.

our circuit as bellow.

thank you.

Hi @Geonbangjini 

ID pin is useless for USB Type-C, the concept does not exist.

CC1/CC2 lines should have each a 5.1K pull-dow to be recognized as a slave device by the Host PC.

 

Regards.
