Hi all, this is my first post here, so please accept my apologies in advance if my questions sound stupid. I have designed a switching system for a guitar amp based on a PIC18F, which I coded using C. This system takes care of all the switching in the amp and it's also enabled to receive midi program change. The switching in the amp is done with 7 buttons in the front panel of the amp or with program 1 to 7 with the midi floorboard. The remaining midi programs can be used to store patches in the PIC18F (for example: channel 1 with reverb and volume boost) that can be recalled easily with the floorboard, so that I can recall frequently used combinations without having to tap-dance on the floorboard. This is already fully implemented (on a breadboard so far) and coded and it works nicely with a commercial midi floorboard. It also works nicely on a simulation I am running in proteus, using the floorboard I found here: http://www.ucapps.de/floorboard.html. This is where I need some advice. Rather than using a commercial floorboard I would like to use this one and customize it. In particular I would like this floorboard to have 7 LEDs that mimic what's going on on the front panel of amp. So, if anything changes in the amp settings, my PIC18F will send a byte to the floorboard's PIC, and the LEDs will switch on and off accordingly. Simple I suppose :P but the problem is that I don't know any assembly. I had a look at the floorboard's code and I wouldn't know where to start from, as it does not make much sense to me. Could you give me a pointer in the right direction? Any help would be very much appreciated. Thanks ;D Mauri
