hello, please I need some help.
I want to measure the frequency of a continuous current motor. then to do this I use an infrared sensor. this sensor is linked to the ADC of the STM. each time the sensor makes a round , the infrared sensor sends a signal to the microcontrollers. so I want to measure the time between two signals arriving at the adc. so how can I use the timer to count this time .
