Hi im a new friend from spain so sorry for my bad english.
My question is:
How should i program my PIC18 for drive with 32 pots, 32 push buttons and 32 leds???
From what I’ve heard, this should be possible.
You’ll need 1xAIN, 1xDINx4, 1xDOUTx4 (not quite sure about that, depends on the way to drive the LEDs), and obviously 1 CORE.
For instance, the MIDIBOX64-Application should handle this (“ghost controllers” will always stay at zero when grounded).
There might be some work waiting, depending on what you want these controls to do 
But maybe you should give us more details on your plans, so that your question can be answered in a better way, and maybe by someone who has more midibox-knowledge than me 8)
thanks, i´ve learned some new interesting things about my midibox project.
i´ll try to send more information about my project.thanks
