Dither pwm
Did you know?
WebTwo hardware dither modes are provided to increase PWM flexibility. The first dither mode increases effective resolution by two bits when resources or clock frequency preclude a standard implementation in the PWM counter. The second dither mode uses a digital input to select one of the two PWM outputs on a cycle-by-cycle basis; this mode is ...

WebIf dither-pwm is false, the value will be changed to the nearest integer submultiple of the make-pulses frequency. A value of zero produces Pulse Density Modulation instead of Pulse Width Modulation. pwmgen.N.dither-pwm bit in/out. Because software-generated PWM uses a fairly slow timebase (several to many microseconds), it has limited resolution.
