See the micropython documentation [1] for a detailed explanation. Some examples are below.
Function callbacks
flag = 0
#note, this callback needs to take one parameter, which is what timer is calling it
def tim_callback(t):
global flag
flag = 1
timer = pyb.Timer(3)
timer.init(freq=1)
timer.callback(tim_callback)
....
timer.deinit()
or, using lambdas
flag = 0
#the use of lambda avoids needing the function to take an argument
def tim_callback():
global flag
flag = 1
timer = pyb.Timer(3)
timer.init(freq=1)
timer.callback(lambda t: tim_callback())
....
timer.deinit()
