Hi all There is several documentation about inplementing UART software using 2 I/O= pin and the timer interrupt for the 21xx fixed point series. The problem is= that I lost the only timer available and i need it (at the same time for ot= her pourposes). Has anyone some idea how to crete a asyncronous link without= using the interrupt timer. Thanks in advance. Fabrizio Miatton |

Hi Fabbrizio, Do you use your both serial ports? If not, you could exploit interrupts from any of SPORT transmitter or reciever. Just set up it in the autobuffering mode and define its timing and buffer length to get proper interrupt period.
