timer

This chapter describes how to use the timer library of LuatOS

Introduction

timer The library uses mcu’s hardware timer, which can be created through the timer library.

Hardware preparation

Any LuatOS-SOC development board

hard blocking

The duration of hard blocking is specified. During the blocking period, no luat code is executed, including the underlying message processing mechanism.

The code is as follows

PROJECT = "TIMER"
VERSION = "1.0.0"

-- Initialize the watchdog with a timeout 10S
wdt.init(10000)

-- print before blocking starts ticks
log.info("ticks", mcu.ticks())
-- The blocking delay is 5000ms, and most projects will not and should not use this method.
-- This demo is just to demonstrate the availability of API methods
-- mdelay will block the operation of the entire lua vm, and will not respond to any interrupts during the blocking period, including uart
timer.mdelay(5000)
-- Print after blocking ends ticks
log.info("ticks", mcu.ticks())

-- Cycle feeding the dog
while true do
    wdt.feed()
end

The log is as follows

I/user.ticks 22
I/user.ticks 5023
