PWM

An Arduino library that deals with PWM stuff like reading from RC Receivers and writing to ESCs

A very crude example from ESC_RC example

#include <PWM.h>

ESC m1(7);      // ESC initialiazed to digital pin 7
RCRecv ch1(2);  // RCRecv initialiazed to digital pin 2

void setup(){}

void loop(){
  m1.write(max(ch1.read() - 100, 0));
}

In the code the first thing defined after including the library is the definition of an ESC object and a RCRecv object, which handle respectively controlling the ESCs speed and reading from an RC reciever.

Then for setting the ESCs speed just use the write function. For reading signal with an RCRecv, just use the read function.

Reference

void ESC::write(unsigned long t):

This function takes in an unsigned long beacause time can't be negative (unsigned) an it can be a lot (long)

void ESC::begin(unsigned long min, unsigned long max):

This function starts the calibration of the ESC an should be called while the ESC isn't connected to power. While the program's waiting for the ESC to have power, update() should be called. (For more info, check out the ESC_Calibration example).

void ESC::calibrate():

This function should be called after begin() and after the batteries haave been connected to the ESC.

void ESC::update():

This function should be called while the program is waiting and the motors should be moving. It sets the speed of the motors to the value of ESC::speed

ESC::speed:

This variable stores the value of the last set or write. It is of type unsigned long

unsigned long RCRecv::read():

This function gives out an unsigned long number for the same reason the write takes it in
