We have a SparkFun servo trigger board and are currently limited with the drive angle. The PWM creates pulses of 1-2ms legths. With this it is possible to reach approx. 125° of servo motion. However, many servos can actually drive 180° if they receive pulse lengths between 500µs and 2500µs. Would it be possible for you to edit the firmware and send me the compiled files which I could just upload? We have the AVRISP mkii programmer.
Thanks in advance!
