Ok understood, i don't criticize i just ask a question, i'm a totally noob concerning all that microcontroller stuff!
The limitation to 32 or 64 is a concern with devices like the CDU using 67 buttons alone, which means two cards for the same Peripheral, with a board that can mangage that huge amount of buttons is that i only need 1 board to make my CDU (i can also placemy board into the same enclosure) ofcourse i'll probably never use 256 buttons for the same device but i have enough room to create the biggest device with only one board.
Anyway i think your work is very interesting and opens more rooms for guys like me that create home cockpits, and i'll follow your project with massive attention!
Looking forward to read it! :thumbup:
