PicoPWM

A C++ way to control PWM for Raspberry Pico C/C++ SDK.

Getting started

Download this library

mkdir lib/
cd lib/
git clone https://github.com/ShellAddicted/PicoPWM

adjust your CMakeLists.txt accordingly:

# Add this line before target_link_libraries()
pico_add_subdirectory(lib/PicoPWM) # Add PicoPWM to your target_link_libraries()
# Example: target_link_libraries(PicoTest pico_stdlib PicoPWM)

Example:

#include <iostream>
#include "picopwm.h"
int main() {
PicoPwm pwm0 = PicoPwm(0);
try {
pwm0.setFrequency(25e3); // set 25khz frequency
} catch (const PicoPwmBaseException& e) {
std::cout << e.what() << std::endl;
}
pwm0.setDutyPercentage(30); // 30% (0%-100%)
// pwm0.setDuty(256); // alternative (0-65536)
return 0;
}
