Debugging my core STM32f4 + diomatrix + fatar keybed

You don't need diodes to check this. You can use a simple jumper cable. 

//edit: I just read TKs post again. So it seems that you would need diodes. Anyway: could you post pictures of your complete setup including the pcb of the keybed?

Now working perfectly !! It was the cable from the adapter to the keybed that was reversed... I guess all my cables were reversed, i'm so stupid...
I'll post a picture of the whole rig when done, i guess it will help other newbies like me.

Tk, FantomXR, thank you so much.

 

Now, time to tweak velocity curves, fantomxr do you have some recommendations?

Cheers,

Next step, i'm trying to make my AINSER8 module work, i followed the schematic of the midibox kb thread,and connected my sustain pedal but i'm only constantly getting this message in midi in:

[13027.175] b0 40 13   Chn# 1  CC# 64 = 19
[13027.185] b0 40 12   Chn# 1  CC# 64 = 18
[13027.190] b0 40 13   Chn# 1  CC# 64 = 19
[13027.200] b0 40 13   Chn# 1  CC# 64 = 19

-Red led is on.
-Jumper J4 is on 1.
-Connected the sustain pedal to J6.A0

i've used the following command:
set kb 1 ain_sustain 1

[13004.399] Keyboard #1: Sustain Pedal assigned to J5.A0!

The weird thing is that on the schematic and PCB,  there's no J5 but only J6.
Here's a quick pic of my setup:

Thanks,

You did a mistake in the wiring. 

You need to put the analog input on the other side of the resistor. 

You should read the documentations which are provided by TK more carefully. This will save you a lot of asking and you will get more quick better results.... so please read through this side again regarding using AINSER8 with KB:
