USB Superspeed Peripherals

Hi.

   

I will make new custom board using fx3 chip. and I want to UART port, but  useable board area is too small to insert UART chip, 

   

example codes that I received from Cypress Inc, have included  USB UART(PID 0x0008) and USB bulk system(PID 0x00F0).

   

Should I use two or more PID in same a Fx3 chip ? If it is possible I want to know how to use that.

   

Regards.

   

Shin.

Hi, 

   

At a time the device will enumerate with only one VID/PID. However, you can have multiple interfaces. You can have two interface, one for your required data streaming, other CDC class. The CDC class will be able to come up as a COM port. However, you need to make sure about the data transfer channels and associated port. Please check about this before designing your board.  We have added (PID 0x0008 in the CDC example, because Cypress drivers will identify this PID as a CDC COM. If you use any other PID, then you can mannual bind that interface with the Cypress serial driver, after which you will be able to communicate with the device even with different PID
