hi thanks for the quick reply, i was on you site/blog all evening looking for info yep multiplexing is a way to go, i use midibox hardware so i could probably reuse the digital input schematics from there, ic 74hc165, i hope i can find some multiplexing code in the link you ve sent me i already own a avrhid from 1010, i attended a workshop there last week, so now i am adding a new project on top of the pile.. i ve also ordered a smt32 primer to start learning some avr stuff... thanks for the input and please let me know if you come up with some ideas/links, what i want to do is to connect buttons and encoders to a the hid object in pure data simone

100 digital inputs is a lot. I think you could use one of many HID boards, then use multiplexers, shift registers, or something like that to get the 100 digital inputs that you need.
Here are some open source HID boards:

hi i am looking for hid based hardware projects, of course they should be open source, i need to drive about 100 digital inputs from buttons and encoders thanks simone
