I have made the functions below (I use a lot of defines that are in
the RF.h file):
void RfTx(char data)
{
RFSet(0);
UART1_TX(data);
}
char RfRx(void)
{
RFSet(1);
return(UART1_RX());
}
void RFSet(int mode)
{
switch(mode){
case 0:
//TX mode
IODIR0=RFModul;
IOSET0=RXSelect;
IOCLR0=TXSelect;
IOCLR0=CHSelect;
break;
case 1:
//RX mode
IODIR0=RFModul;
IOCLR0=RXSelect;
IOSET0=TXSelect;
IOCLR0=CHSelect;
break;
default:
break;
}
}
For now I have only testet the system one way. That means that I
have set one MCB to send and another to receive. By that I wouldn't
mean that it was necessary to have any delay after switching (as I
don't do that). I call the RfTx function from inside the while loop
in main of the transmitting MCB end RfRx from inside the while loop
of the receiving MCB. I Really can't see the why this is bothering
me so much.
