Test Mode

A Test Mode has been implemented since firmware 1.04 in order to test the unit while building it.

Pressing F1 and F2 and Power On unit load to Test Mode.

This allows you to test the switchs and LEDs and potentiometers of the interface.

Pressing a switch highlights the LED next to it. Moving a potentiometer shows its position between 0 and 127. The display is used to show you the action. It does output similar messages through Serial USB too (115 KBauds). This allows you to see which switch/LED is defective or which potentiometer has jitter (99% it is an unsoldered potentiometer).

 

Pressing KEY2 and KEY3 and KEY4 reboots the System (and leave Test Mode).

 

Moreover a permanent test has been implemented to test the Midi connection by SysEx messages. The following messages need to be sent to the Matrix Ctrlr Midi Core input :

The Ctrlr answers on its display to those two messages ????

arduino Mega pin tester application

A short application to test your arduino mega and detect if there are very thin short or cold solder joints between the pins/connectors. Useful if your buttons are not detected for example (we had a defective board with a short between pin 10 and 11, disabling SRIO function scanning the buttons).

Simply upload the sketch and then with a single wire you can monitor through Serial at 115200 bauds that the pin is good : pin 13 is the output pin alternating a state 1/0 while Serial indicates if the tested pin is working. All pins are tested so you can pass from one pin to another with the monitor window opened without rebooting, simply by moving the wire.

pin10 is tested on the picture below :

 

Increase the delay(5) to delay(150) to see the source output pin blinking. Sketch to download :
