Library 38- External interrupts for STM32F4

A new library is here. 38th are external interrupts. This library allows you to very easly use external interrupts for your needs with just one function and function handler. I have written everything you need to start. For more informations on how external interrupts works on STM32F4 with pins and lines and so on, you should look at my external interrupts tutorial. I tried explain there everything as best as I can. I think it’s quite understandable. I will just...
