![]() ![]() For example, we can use a timer interrupt to toggle the LED after every one second. Timers available in ESP boards can also be used to perform a certain task periodically after a certain amount of time. On top of that MicroPython machine class also supports virtual timer for ESP32. MicroPython Timer API supports allf four hardware timers. The timing of these timers depends upon the clock and varies from one board to the other. Tim.init(period=5000, mode=Timer.ONE_SHOT, callback=lambda t:print(1)) ESP32 TimersĮSP32 had a total of 4 hardware timers(Timer0, Timer1, Timer2, Timer3) which are all 64 bit based on 16-bit pre-scalers. We can use the machine.Timer class with timer ID of -1 to use virtual timers. But it provides API for virtual timers (RTOS bases). ![]() But one important point to note here is that at the time of writing this article, MicroPython Timer class from machine module does not support Timers of ESP8266. We must use Timer1 as the Timer0 is used by the WiFi. ![]() ![]() Timers in ESP8266ĮSP8266 has two timers: Timer0 and Timer1. Now first let’s see the number of hardware Timer modules are supported by both ESP32 and ESP8266 boards and their API support in MicroPython.
