|
|
* This demo is used for manufacturing testing on the TGA Pro Expansion
|
|
* Control Board.
|
|
*
|
|
* This will test the following on the TGA Pro:
|
|
*
|
|
* - Audio INPUT and OUTPUT JACKS
|
|
* - Midi INPUT and Midi OUTPUT jacks
|
|
* - MEM0 (if installed)
|
|
* - User LED
|
|
*
|
|
* This will also test the Expansion Control Board (if installed):
|
|
*
|
|
* - three POT knobs
|
|
* - two pushbutton SWitches
|
|
* - two LEDs
|
|
* - headphone output
|
|
*
|
|
* SETUP INSTRUCTIONS:
|
|
*
|
|
* 1) Connect an audio source to AUDIO INPUT.
|
|
* 2) Connect AUDIO OUTPUT to amp, stereo, headphone amplifier, etc.
|
|
* 3) if testing the MIDI ports, connect a MIDI cable between MIDI INPUT and MIDI OUTPUT
|
|
* 4) comment out any tests you want to skip
|
|
* 5) Compile and run the demo on your Teensy with TGA Pro.
|
|
* 6) Launch the Arduino Serial Monitor to see results.
|
|
*
|
|
* TESTING INSTRUCTIONS:
|
|
*
|
|
* 1) Check the Serial Monitor for the results of the MIDI testing, and external memory testing.
|
|
* 2) Confirm that the audio sent to the INPUT is coming out the OUTPUT.
|
|
* 3) Confirm the User LED is blinking every 1 or 2 seconds
|
|
*
|
|
* If using the Expansion Control Board:
|
|
*
|
|
* 1) Try pushing the pushbuttons. When pushed, they should turn on their corresponding LED.
|
|
* 2) Try turn each of the knobs one at a time. They should adjust the volume.
|
