Hello, I have a problem with stimulus file in MPLAB 7.30. I am debugging software where PIC is receiving packets from simple radiomodem (868 MHz, AM, OOK). The transmitting side works OK, and I am trying to debug the receiver. I used the SCL generator in MPLAB and I created the stimulus file which should drive the receiving pin of the PIC in MPSIM. In the SCL generator, the whole thing looks like: Time units us Time RB0 0 0 5000000 1 5004000 0 and so on It means that at time 0, the RB0 pin is low. After 5 seconds, the RB0 goes high (start of the transmittion), after 4 ms, RB0 goes low (first start bit) etc. But, when I generate the SCL file and when I attach it to the simulation, MPLAB react correctly to the first event (RB0 going high after 5 seconds), but the simulator ignore the rest of the file. RB0 never goes low after 4 ms and the rest of the file (the whole simulated transmittion) is ignored. Anyone have some idea where I am wrong ?
