Test Procedure for DINX4

Testing/Troubleshooting
1

Is there a sure-fire way to test a DINX4 board.  I have run the srio_interconnection test_v1 and I have 5 volts on the sc and rc when I should.  I have 5 volts between ground on the core and Vd on each DIN I have checked.  Vs on the J3 through J6 is ok back to ground on the core.  D0 through D7 on J3 through J6 all have 5 volts.

After I ran the srio_interconnection_test_v1, I loaded the midio128_v2_1d hex file with MIOS Studio.

I thought if I connected one of the D0 - D7 pins to Vs, I would get a note-on in either MIOS Studio or MIDI-OX.

I guess I’m confused.

Thanks.

Did you solve this in the meantime?

There is a simple test which ensures that the MIDIO128 is uploaded correctly: just disconnect the DINX4 module, and shortly connect J9:SI (the serial input) to ground.

The core should send 128 MIDI messages
