Pyboard timer terminal callback function problem [Copy link]

 

The timer executes the callback function once every 2ms. Print the timer value,

When using lambda function, it can be printed many times (25 lines)

When a function is defined with 20 lines and then called in a callback function, it can only be printed once. Why is this?

The calling method is wrong. Only the function name is required, without brackets and parameters. This is equivalent to using the function running result as the callback function parameter.

In addition, the print function is very slow. If you have high performance requirements, try not to use print in interrupts.
