I was planning to do something similar to the LED code but i was going to use a whole byte for the position to simplify all of the code. The first chip can then pass a byte right from the buffer i already have for the LEDs and the second can turn the output on for an amount of time that is directly proportional to the value of the byte.

I think the best thing to do is have the servo PIC make one of its pins high during the 18ms of waiting. The LED PIC can only send data while that pin is high. I can use TMR0 to get the 18ms and a simple pauseus or pulsout command for the short pulse.

Ive checked both Rapid and Maplin for a 16F688 but they dont stock it. Can you buy directly from Microchip? It might be worth buying from elsewhere if the chips are going to be that much cheaper than the next best thing that Rapid stock.

I only have the need for 2 servos at the moment but i may need 3 for some other projects. I think thats about it though
