#300 TheMatrix/LedTest

Testing The Matrix (Boldport Club project #11) with @luckyresistor’s LRAS1130 library

Build

Notes

Testing LEAP#298 TheMatrix - Boldport Club Project #11 - with the LRAS1130 Arduino library from @luckyresistor.

I’m using a version of the LedTest.ino script.

Visual Result

In the initial test I found two LEDs that needed a connection fix:

After fixing those LEDs, all are performing correctly. However note the intensity of a few LEDs is not the same as others. As far as I can tell, it may be a problem with the LEDs themselves.

Test Output

The Matrix is laid out in a 5x24 matrix as described in the datasheet (Figure 54). This means the LED addresses A thu F are not populated i.e. only 10 out of every 16 LED addresses are used.

For the LEDs that are populated, the test script says they are all OK:
