Library 48- Measure PWM input signal with STM32F4
First library in 2015 is here. With it, you will be able to measure PWM input signal from “other world”. STM32F4’s timers have capability to make an interrupt on edge, when signal is active on input pin for specific timer. This allows us, to measure signal in input. With a simple calculations, we can detect frequency of signal and duty cycle. Of course, this is not veery accurate, but with 168MHz F407 device, using 32bit TIM2 (high resolution) I got...
