How do I set the GPIO output(s) to turn on and off quickly (pulse)?

Last Updated: October 14, 2015

You can turn GPIO outputs on/off quickly using the Pause command.

  1. Create an Interactive presentation in BrightAuthor (see Chapter 4 -- Making a Presentation Interactive in the BrightAuthor User Guide for more details).
  2. Open the media state or event where you want the GPIO pulse to occur.
  3. Click the Advanced tab.
  4. Use the Add Command button to add three commands.
  5. Set the first command to GPIO -- On. Enter the GPIO pin connected to the LED (it must be configured as an output pin in File > Presentation Properties > I/O).
  6. Set the second command to Other -- Pause. Enter a short length of time (in milliseconds) to pause.
  7. Set the third command to GPIO -- Off. Select the GPIO pin used in step 5.

    OK - what if I need to "blink" this output or multiple outputs for a minute?  4 times a second x 60 second = 360 commands to put in here.  Is there a simple way to put this in once and then loop it until another event takes it out of this state?  Can I use an event handler instead of triggering this with a video or graphic file?  Or can I go between two event handlers, each with a set on on-pause-off-pause commands and trigger the other event handler to continue the same?  Could really use a Set Panel Output - blink (slow, med, fast) but for the GPIO instead.
