Thanks for replying.
I am trying to establish an RF link with the PIC to control a car using a PC parallel port.
I planned to do it this way:
The 4 inputs from the Parallel port represent (forward, left, right, brake)
The PIC listens for signals from the parallel port at its I/O pins. If a 1 0 0 0 is sent, then the PIC will know it is going forward.
The PC should also be able to monitor the condition of the car battery and temperature. Unfortunately, seems like there is only 8 data pins for the pc parallel port. So the other 4 pins is used for monitoring purposes.
Unfortunately...again, the ADC for the PIC is 10 bits, so i am having trouble sending the info back in 4 bits.
Any advice?
