Forum Post: 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 ?

Following is my routine code to receive a string. void UART_GETSTRING(unsigned char * string, int length) { unsigned int i=0; while(i<length) { string[i]=UART_GETCHAR(); i++; } } unsigned char UART_getchar() //Waits for a valid char from the UART { check=0; IE2 |= UCA0RXIE; while(1) { if(check==1) { check=0; break; } } IE2 &= ~UCA0RXIE; return rx_char; } #pragma vector=USCIAB0RX_VECTOR __interrupt void USCI0RX_ISR(void) { while (!(IFG2&UCA0RXIFG)); // USCI_A0 TX buffer ready? rx_char=UCA0RXBUF; check=1; }
