Data sending code:
void UartPutchar(unsigned char c)
{
while(!(IFG2 & UCA0TXIFG)); //Waiting to be sent is empty
UCA0TXBUF=c;
IFG2 &=~UCA0RXIFG;
}
Just change the value of the buf variable
Receive data
#pragma vector=USCIAB0RX_VECTOR
__interrupt void USCI0RX_ISR(void)
{
while (!(IFG2&UCA0TXIFG)); // Waiting for sending to be completed
//UCA0TXBUF = UCA0RXBUF; // TX -> RXed character
temp=UCA0RXBUF;
// In this way, the read data is put into temp, and then write the judgment program below to complete the serial port control
}
This is the receive and send function code. There are many articles about other interrupt settings.
