如何在Arduino上将参数传递给回调函数以进行计时器中断？

Question

I want a timer interrupt to call a function with a set of parameters on an Arduino. I have looked at the Timer1 library, but it seems unable to be used in a way to pass parameters to the callback function.

Answer 1

You can't. You'll have to use some sort of global struct to save your current state. When the callback is used, get the data you need from that struct.

Answer 2

You can wrap your callback into a parameterless function. This wrapper function can pass whatever parameters you want into your function.
