as a reference you can use button examples from my old posts

InterruptIn with I2C interface on F042K6

Ahoj, please use these symbols ``` before and after your code in your post. Then it looks nicely and it is better readable. Since you probably use the Mbed2, it should not so big impact but anyway. During an ISR is not recommended of using a long wait, a printf and another slow, blocking or complicated functions. You want to have ISR shortest as is possible. You can set a flag in the ISR and the flag can be processed and cleaned in the main loop. For example like bellow. #include "mbed.h" …

How to pause and resume song using Mbed code

#include "mbed.h" InterruptIn button(BUTTON1); volatile bool pressed = false; void buttonPress() { if(!pressed) pressed = true; } int main() { button.fall(callback(&buttonPress)); // main thread while(1) { if(pressed) { // do something magic here // clean after job done for another intrrupt pressed = false; } // rest of loop } } But there are many variants how you can solve it and i…
