Ameba MicroPython: [RTL8722CSM] [RTL8722DM] Timer - Periodical timer

Materials

• Ameba x 1

Steps

There are 3 sets of general timers available to user, each at 32KHz, they are timer 1/2/3.
Here we use timer 1 as example to demonstrate how a periodical timer works.

Copy and paste the first 3 lines of code into REPL to see its effect.

from machine import Timer
t = Timer(1) # Use Timer 1/2/3 only
t.start(2000000, t.PERIODICAL) # Set GTimer fired periodically at duration of 2 seconds, printing text on the terminal

# To stop the periodical timer, type
t.stop()

A text of “–timer triggered. to stop: type t.stop()–” will be printed on the terminal every 2 seconds.To stop the timer, simply type t.stop().
