Pulse counting works by generating a narrow, fixed-width square wave pulse at a set point in ... his videos talking about the mysteries of RF modulation; SSB, anyone?

In this video, [Jack] talks about various types of pulse width modulation (PWM). You can use PWM to control the speed of a motor, the brightness of a LED, or to generate analog waveforms.

The APB PWM Module is a standard APB peripheral that generates a programmable duty cycle output signal. The frequency of the output waveform is either PCLK/256 or PCLK/4096, depending on whether a ...
