Hello.
I'm using the following two functions to send /receive data from UART0
Rx
================================================
void uart0Receive(byte* uartRxBuf, unsigned short uartRxBufLength) {
unsigned short uartRxIndex;
U0CSR |= 0x40;
URX0IF = 0;
for (uartRxIndex = 0; uartRxIndex < uartRxBufLength; uartRxIndex++)
{
while( !URX0IF );
uartRxBuf[uartRxIndex] = U0DBUF;
URX0IF = 0;
}
}
Tx
===================================
void uart0Send(byte* uartTxBuf, unsigned short uartTxBufLength) {
unsigned short uartTxIndex;
UTX0IF = 0;
for (uartTxIndex = 0; uartTxIndex < uartTxBufLength; uartTxIndex++)
{
U0DBUF = uartTxBuf[uartTxIndex];
while( !UTX0IF );
UTX0IF = 0;
}
}
The rx part works perfect until I send data, after that I can't receive anything, just hang on while( !URX0IF );
Any suggestions?
