Periodic Operation
This library allows users to call a function periodically.
MsTimer2, one of types, is compatible with Arduino One described in Arduino Playground. It is necessary to specify #include <MsTimer2.h> for using MsTimer2.
MsTimer2::set
- Description
- Specifies a call back function executed in the specified interval timer interrupt handler.
- Syntax
- MsTimer2::set(unsigned long ms, void (*function)())
- Parameters
- ms: Interval(ms)
function: Function name - Returns
- None
- Notes
- The handler is executed by disabled interrupt. In case of executing with use of interrupt, permit an interrupt by interrupt().
MsTimer2::start
- Description
- Start the timer after set
- Syntax
- MsTimer2::start()
- Parameters
- None
- Returns
- None
MsTimer2::stop
- Description
- Stop the timer
- Syntax
- MsTimer2::stop()
- Parameters
- None
- Returns
- None
Sample Program
This sample tries to use MsTimer2.
#include <Arduino.h>
#include <MsTimer2.h>
int ledpin = PIN_LED_GREEN;
void flash() {
static boolean output = HIGH;
digitalWrite(ledpin, output);
output = !output;
}
void setup() {
pinMode(ledpin, OUTPUT);
MsTimer2::set(500, flash); // 500ms period
MsTimer2::start();
}
void loop() {
}
