Servo control with the PIC Embedded controller

See also:

• Servo control with the Atmel AVR embedded controller -- the OpenServo board goes *inside* the servo case, converting it from a "analog" servo to a "digital" servo. In addition to accepting position commands, it also accepts speed and cubic motion curve commands, and also sends back motor current and other information. Open source.

Questions:

• kyanpu at singnet.com.sg asks: " camp ask : i need help on how to pulse the servo motor directly using one of the outpin of portb, without the use of TMR2 PWM technique. "

  There are several non TMR2 PWM versions to be found in the PWM link above +

• Scott R Pierce asks:

  Can anyone point me to information on how to take servo pulses from an R/C receiver (RX Unit) and convert those pulses to an integer form? I would like to make sort of a two channel mixing unit for my airplane. I'd take two servo pulses, convert them into integers, do some calculations on them, then convert them back into PWM for the servos. Thanks in advance!
