I'm using a Nucleo Board with a STM32F030 fitted.I wanted to use the callback function mentioned above to clear an output that is set as part of a separate pin handling interrupt. I cannot find any material relating to needing to setup anything for t...
How correctly measure speed with an hall effect sensor using TIMER
Hello, I'm using a timer to measure the frequency of an Hall effect speed sensor.The point here is that the routine that measure the frequency is triggered by the falling edge of the signal. Then the difference is calculated between two interval to r...
Lockup problem. stm32L552
