MSP430F5529: BackChannel UART communication with MSP430F5529 USB LaunchPad

Kei Ishibe

Part Number: MSP430F5529

When I use P4.4(UCA1TXD) and P4.5(UCA1RXD), I can send but not receive. What can I think?

The following UART communication using P3.3 and P3.4 can be sent and received.

Is there a difference in usage between P3 and P4?

Thank you,

It is same, but P3.3 and P3.4 are related to UCA0, and P4.4 and P4.5 are related to UCA1. So everything must be changed (including ISR if it is used) to UCA1.
