Forum Post: RE: I want to receive a string or a character through UART in msp430g2553 but not able to receive even a single character it. If a character arrives my IFG2 flag is not getting set so what should i do in this code ?

What equipment or device is sending the string that you expect to receive? How is your G2552 interfaced (hardware wise) to that equipment or device? For the G2553, I do not see how you initialize the UART and the UART pins. I also do not see how you set up SMCLK or ACLK.
