PWM Feature request

Post by willishf »

Wanted to see if it was possible to add support for the "limit switches" could be used for PWM output to control servo. Assuming the input pins are on microprocessor and if those pins can be either input/output configured then a cheap software feature for future firmware release.

The three pin header on the roboclaw board is already setup for servos with + in the middle and signal/ground on external pins.

The S4 and S5 pins are not on pins the main processor support PWM on so this is not possible. Software Bit banged PWM would also be very jittery. We are also nearly maxed on the firmware.
