IIC MIDI problem

Testing/Troubleshooting

Hello

I have a problem with get working iic_midi_sw_loopback_v1_0 application properly.

The core module work good with lcd, also I have 2 modules IIC MIDI with latest software related to PIC16f88.

After upload iic_midi_sw_loopback_v1_0 application I see on lcd

, so MIOS recognized properly IIC MIDI modules.

After bootup red and yellow leds blink and green led still light on.

Everything look good, but incoming midi data to the core module are not forwarding to IIC MIDI slaves. I left R1 pins on both IIC MIDI modules open.

How can I try to debug this situation? :slight_smile:

p.s. when I send any midi data to midi in on IIC MIDI module then I get the same midi data on IIC MIDI out, also red and yellow leds  flashing.

thanks

edit:  I have connected leds in oposite way than this picture

thats fine, the modules are working.

Core MIDI In data is not forwarded to the IIC slaves (see also main.c)

Concerning the LEDs: the anodes (-> larger legs) are correctly marked with a “+” sign, I think the detail which confuses is the wrong orientation of the LED footprint
