Lab 12. Embedded systems shape the world. Interrupts

Well, well, here I let you a little demo of how it looks like for me the implementation of the Lab 12, interrupts.
It is just a little program that uses Systick and in the interrupt service routine just implements a little FMS (it may even be a counter) to just change the status of the push button in relation with the output tone 440Hz (A for tunning). If you click once, the tone is hold, if you click again the tone is off and on and on.

No more texto and just see the pictures and the little video :-)
