for ControlOut with data, i think it is follow:

Setup Data0 Ack Out Data1 ack .... Out Data1/0 ack In Data1 ack void My_Status_In (void) { //process recived data <===== the code can not be executed} but for ControlOut without data, it can be executed. where is error ? I use STR710 and IAR. [ This message was edited by: shangdawei on 26-03-2007 08:08 ]
