Hi!
I'd like to connect the CM5 box with a serial device...
What is the best choice to make the CM5 to listen to the port?
1. An interrupt driven routine?
2. A simple loop as
while (true){
command =TxD8Hex (RXD1_DATA);
make_my_things(command);
}
?
Thank you in advance.

I've tested the polling option at 57000 bps with great sucess
(the answer was here, in the forum)

- Code: Select all
byte RxSerial (void){
if (RXD1_READY) return(RXD1_DATA);
else return (0x0);
}
main (void) {
while(1){
key = RxSerial () ;
if (key != 0){
if (key==KEY1) command = OP1 ;
if (key==KEY2) command = OP2 ;
}
if (command==OP1) make_my_things();
}
}
