You can use this to make an LED get brighter or dimmer, control a servomotor, etc. It is technically possible to push the frequency to 8MHz, but the range of possible power duties get stupidly small by that point. We will show it based on the STM32F4-Discovery board, however controlling the timers of other STM32 devices is very similar. FreqCount measures the frequency of a signal by counting the number of pulses during a fixed time. for a pan-tilt unit) through a PWM signal on an ARM Conrtex-M3. 4 Comments.
