You should clear RI before the while loop in GetChar. The REN bit should also be set before clearing RI, and cleared after the while loop.

Thanks for the reply. Yes, sure.

Hi,

Have you set port 01 and 02 to RXD and TXD by writing?

P0_ALT.1 = 1; //Set P01 to RXD
P0_ALT.2 = 1; //Set P02 to TXD

The direction of UART RXD also depends on the setting of P0_DIR.1 (should be set to 1 for input).

Best regards,

Øyvind
