I would like to use an xbee module to directly drive (without mcc/mcu) a common hobby servo. As I understand it the xbee pwm pin puts out a pwm signal with a period of about 64usec, which for all effective purposes is more like an analog signal (especially with a simple rc filter)... From 0-3.3v
I'd like to be able to use that "analog" voltage to drive a typical servo that requires a 1-2ms pulse width. Without resorting to a microcontroller, is there way to use that variable voltage signal to control the rotation of the servo by getting the correct pwm signal? Extreme positional accuracy isn't really a concern, as I'm only really interested in 0, 90, and 180 degrees or there about.
