Hi All, I've just been trying to put the finishing touches to my MIDI organ console, but in the process of doing so, I think I shorted something (PIC got very hot...) and since then my DIN modules won't work. After a lot of swearing and pulling of hair I think I've tracked down the problem: -DIN modules work correctly, I've tested them with my other core module -I can manually short the input terminals to the core module and it picks up the fake "inputs" -Clock out (RD3 on PIC) is running nicely -Ld pin (RD2 on PIC) isn't pulsing (I've tested this on a scope at work) So my question is (finally), have I fried my PIC beyond all repair or might a complete re-flash work? I can reprogram the core via MIDI so most of it is working (including the LCD). I think I saw a message on the LCD when I installed MIOS 1.8 (to try and fix the problem) which said "fixing...." but I didn't spot what it thought it was fixing. Thanks for any help you can give, Chris.
