#67184 - RE: pulse counter Responding to: ???'s previous message |
hi,
P1.2 is not an external counter source entrance. Use P3.4 or P3.5 instead. I am using p1.2 for pulse counting ... So you need polling this pin permanently and it is not good idea. Hardware of C51 is enough to support external events` counting itself. Use T0 or T1 pin as input and configure timer 0 or timer 1 as counter clocked with external source. Regards, Oleg |
