I have a water flow rate sensor which I want to read with my STM32F411RE Nucleo-64 board. The output signal is a frequency. How can I read the signal? The sensor has following properties:Flow Range = 1 - 15 L/minPulses per Liter = 2200Frequency Outpu...

Thanks for your reply! So, the input capture will capture both the frequency of the timer and cause the interrupt which captures the frequency of the pin to which the sensor is connected to? If so, how do I tell the µcontroller that e.g. pin PB_8 is ...

Thanks for your reply! I think I got the jist of your idea for using TIM. I read the frequency from the sensor input signal with GPIO_ReadPin. Simultaneously I read the timer frequency as the GPIO signal goes high and then again when the signal goes ...
