ok... assuming phil's data, this is what i sofar understand: i should send a signal to the servo with 2ms (5V) to rotate it at maximum position and 1ms (5V) for minimum position. should i send this signal once (just sigle pulse) for the servo to rotate, say for maximum position?

Servos can be modified to make them rotate 360. I've done it for a number of GWS servos. If the FS3003 uses plastic gears (and I think it does) then its pretty easy. you will have to remove the "nub" that prevents rotation and disconnect the feed-back pot. google for servo modifi

What's the fastest way to get the exclusive or, of four bits in a register? 0000 = 0 0001 = 1 0010 = 1 0011 = 0 0100 = 1 0101 = 0 0110 = 0 0111 = 0 and so on... Not for a parity generator, but I think it ends up as the same problem.

Your first step is to look at the code and see what compiler it was written for. Atmel follow good practice and specify the target device and compiler in a comment block at the start of the code. If it's for the IAR then you're OK. If not your're going to have to port the code, w
