Thread: TimerOne library does not function

  1. #1

    TimerOne library does not function

    I am running a modified version of this code on a mega.

    AC_Dimmer

    I want to run it on a teensy 3.0. I finally figured out how to get the interrupt pin to work, now I want to attach a timer to it and have previously used the TimerOne library. I also tried both examples which come with the TimerOne library and they both fail with the same error listing. Can anyone help me to get this working without the library or will this library interaction be fixed shortly (beta 8)? There are a number of reasons I want to use the teensy 3.0 on this project and an arduino or even a teensy 2.0 is not adequate.

    my line 24 is the include of the TimerOne library...

    When I try to compile it, it pukes with this error:

    TCCR1B and the others aren't declared because the TimerOne library you're using hasn't been ported to Teensy3 yet.
    I was going to post an example of code that runs a timer in Teensy3 but discovered that it doesn't run in beta8. So, I'm holding off until the beta8 problem is resolved.
    [edit] Found it.
    I posted some code in http://forum.pjrc.com/threads/489-T3-beta-8-regression which blinks an LED using a Teensy3 timer interrupt. For beta7 or beta8 it requires a fix described in my second post in http://forum.pjrc.com/threads/14-Tee...and-interrupts. Perhaps it will give you a start.

    Ok, I have some time to work on this and am trying to make sure I understand what all the code does/means...

    I want to trigger a timer based on an interrupt pin (pin 16 for example) and want it to run at 60hz and want to borrow your code if I can. I am chopping the A/C waveform and am using the ZC detector on pin 16. When it sees a rising edge, I want to start a timer and divide the time into 255 slices.

    I am pretty lost here, but I have a trigger on pin 16 and want to start a timer from the rising edge. I want that :

    can anyone help me get this arduino sketch ported over to Teensy 3?

    These are the lines of the code I am trying to get replaced in teensy 3 so it will compile.

    Code:
      
    // for timer function 
    int freqStep = 65;    // Set the delay for the frequency of power (65 for 60Hz, 78 for 50Hz) per step (using 128 steps)
    // freqStep may need some adjustment depending on your power formula 
    // is (500000/AC_freq)/NumSteps = freqStep
    
    attachInterrupt(interrupt_pin, zero_cross_detect, RISING);   // Attach an Interupt to Pin 21 (interupt 2) for Zero Cross Detection
      Timer1.initialize(freqStep);                                 // Initialize TimerOne library for the freq we need
      Timer1.attachInterrupt(AC_out_check, freqStep);      
      // Use the TimerOne Library to attach an interrupt to the function we use to check to see if it is 
      // the right time to fire the triac.  This function will now run every freqStep in microseconds.
    TIA,

    Keith
