bosone Posted May 14, 2006 Report Posted May 14, 2006 hi!i have a small keypad with 12 keys arranged in a matrix (like the PC one).i know that with some great tweaking one can handle the matrix encoding/decoding with MIOS but... is there a "standalone" version?what i'm looking for is some simple schematic to "convert" the keypad matrix into 12 standard on/on switches (or even less, i need only 8 buttons of the 12 present)then, i will simply connect these 12 ouput to a DIN module of the midibox without MIOS tweaking...i have also an old pic 16f874/7 to use for this task, if needed Quote
