PWM.h

Purpose: PWM channels, output pins, and timer resolutions.

Namespace: atmega328p::pwm

The six output-compare channels are:

Channel	Timer	Pin	Resolution
OC0A	Timer0	PD6	8-bit
OC0B	Timer0	PD5	8-bit
OC1A	Timer1	PB1	16-bit
OC1B	Timer1	PB2	16-bit
OC2A	Timer2	PB3	8-bit
OC2B	Timer2	PD3	8-bit

#include <atmega328p/PWM.h>
 
namespace mcu = atmega328p;
 
constexpr mcu::pwm::Channel output = mcu::pwm::Channel::OC1A;
constexpr mcu::pwm::OutputPin pin = mcu::pwm::OutputPin::OC1A;
 
static_assert(mcu::pwm::channel_count == 6, "PWM channels");

Channels on the same timer share its time base and are not independent PWM generators.
