Posted on May 23, 2013 at 17:11Hello,I want to do something ''simple'': measuring the time duration between two button presses. In my application, the user can press a button repetitively and the STM32F4 will calculate the time between two pulses to...
Posted on May 08, 2014 at 23:04Hello everybody. I have a working code with stm32f407 and freertos. I want to use stop mode at the microcontroller. I read the tickless mode at freertos, this is for use the sleep mode. If I define this mode, my code g...
