Error detection mode performed

The evaluation of the error detection over USB:

1.

If the jumpers P20, P21 and P22 are closed and the jumpers P1, P2 and P3 are open,

no defective LED should be reported by the application graphically after pressing the

button "Perform error detection". See Figure 12.

2.

Moving the jumper from P21 to P2 should result in the indication of a simulated

defective green LED in the first row and the second column and a simulated defective

blue LED in the third row and the third column.

3.

Exit the application and disconnect the board before testing another.
