FlexTimer2 on Teensy 3

[badhairday]

Hi,

I am moving some code from a Teensy 2 to a 3. I am getting an error using FlexTimer2 that it only works on an AVR architecture. Would this be an easy fix or is there a better, similar library to use? I don't want to spend a lot of time reinventing the wheel.

Thanks,
Chris

Sorry if I did not give enough details. Using Teesyduino, the code below compiles using a Teensy 2 but on a Teensy 3 errors with the following:

In file included from sketch_may12a.ino:1:0:
/Users/chris/Documents/Arduino/libraries/FlexiTimer2/FlexiTimer2.h:7:2: error: #error FlexiTimer2 library only works on AVR architecture

My question is would it be an easy fix (change) to FlexTimer2 to make it compatible with the ARM architecture.

Thanks,
Chris

#include <FlexiTimer2.h>


void setup() {
  Serial.begin(9600);
  pinMode(11, OUTPUT);
  FlexiTimer2::set(50, flash); // 500ms period
  FlexiTimer2::start();
} 
  
void flash() {
  static boolean output = HIGH;   
  digitalWrite(11, output);
  output = !output;
}

void loop(){
  Serial.println("Looping");
  delay(1000);
}

Teensy 3.0 has IntervalTimer for this purpose. It works better than FlexiTimer2, with higher precision, up to 4 separate timers, and without disrupting any of the PWM pins.

Thanks Paul for the quick reply. IntervalTimer works for me.
