So maybe I can use another PIC to control touchpad/ribbon? I thought of a sub-menu 'touchpad' where you would have: 1) Callibration - just like the callibration of a joystick - move your finger around touchpad for a few times. PIC should remember the maximal and the minimal values and create some kind of 'virtual scale' and convert it to midi values 0..127 (touchpads at x=0 y=0 point have some resistance, not 0) 2) Kind of 'mode' of work. The first can be 'relative' - PIC only add or subtract values, the pressing point doesn't matter, only the direction of movement. The second - the values sent depend on the place touched. Is it possible to add these features to the existing mhbp or I should use other PIC for handling menu/display and/or other for calculating and remembering those things? What do you guys think about it?
