Hello again,
after a long time of aquiring the parts for this project I have now started the actual process. I have hookd up the organ foot pedals as in the document mbhp_dinx4_32buttons.pdf I have hooked up the LCD referrig to the document mbhp_lcd_4bit_mios8.pdf and it seems to work fine. I hve the MIOS 1.9V opening as the chip seemed to have MIOS preinstalled. Also, Hello World!
Now to the task itself. I am a complete newbie to coding. My goal is pretty straight forward and simple but I really just can´t pick up on anything that I have read on the documentation. I´m getting really confused as all the projects here seem to be a lot more abitious than my plans so most of the stuff just goes over my head. I hope I would get someone to help me with this relatively simple design.
I have tested MIOS and the chip compatibility by uploading the ain64_din128_dout128_v2c project hex onto the chip. I have grounded all AINpins on the core board and the screen now says:
AIN DIN DOUT
1: 0 1o 1o
DIN R5 board terminal J1 is hooked up to core terminal J9 and the keys of the pedals are attached to the J4 and J5 as I wasn´t sure if the first, J3 would be for the utility buttons. The keys themselves should act just as triggers, no dynamics or anything. Just a note on as long as the key is held down and then note off after release. Simple. But right now I get no activity from the DIN pins. I have checdked that the shift registers
The next step would be to have two buttons (momentary foot switches) to transpose oct up/oct down. And then another pair of foot switches for MIDI Ch up/down. And I would like two 7-segment leds for each pair of foot switches to indicate the current status of that parameter.

I hope to get some feedback at least.
