TM4C123GH6PM: USB Type C connector on Tiva-C and the lack of USBID

can altineller
Expert 1500 points
Part Number: TM4C123GH6PM

Hello,

I would like to replace the usb micro type connector with usb type c connector on my custom made TM4C123GH6PM board. I have done my research and basically:

A6 and B6 are connected together as DP

A7 and B7 are connected together as DM

CC1 and CC2 are pulled down with 5.1K resistors individually.

In my custom board, I have usbvbus, connected to PB1 with 100ohm resistor, and the usbid pin from the usb2 connector is connected to PB0 with 100ohm resistor too.

However the usb-c connector has no usbid pin. Instead CC1 and CC2 can be used to indicate if there is nor no cable. Ideally I would want to use an or gate to read CC1 and CC2 and feed the output to PB0 pin. to get equivalent connection with the usb-c connector, but instead I have decided to ask the forum: Has anyone used a type-c connector with the tm4c123gh6pm? if so are there any remarks about it?

Any comments/ideas/help greatly appreciated.

Best Regards,

C.A.
