PIC with RF module as remote control

17uS doesn't sound a lot?, it shouldn't upset the Manchester routines too much - but what is the interrupt routine doing?.

The interrupt routine is doing multiplexing for four 7-segment displays, and counting down for dual counter.

After testing yesterday, I have these results:
Transmitter send the same signal continuously twice, it worked perfect if crystal is used for the receiver and it worked not very well with the internal RC oscillator of the receiver, but it is still working.

Thanks
