I hooked up a pic using modbus and a mpg to the pic, when i got i get 10,11,12,13,12,11 counter or clockwise.... i'm thinking of just adding a second parallel port.. on a parallel port is it possible if using pins 2 to 9 to make a button array lets say using 4 input pins for buttons giving 1000,0100,0010,0001,1100,0110 ... etc i'm wondering if this could be mapped into the brain controll take oeminput1 and compare it to the other inputs.. anyone try this or have any ideas?
