[sdiy] bizarre pic-midi issues

[Karl Ekdahl]

Hi list, i've stumbled upon some very bizarre PIC MIDI issues. I'm able to send MIDI just fine, but when i try to receive it i half the time get junk and half the time get good data. Usually (for me), the issue seems to be to find the right speed settings, but as the transmission works fine that can't be it. The hardware seems rock solid so i really don't understand what's going on... any hints or thoughts would be awesome! Oh yeah it seems to work "okay" if i use the PIC ONLY to process MIDI, but if i try and do anything else in the same loop i only get garbage - that's on a PIC running at 12MHZ - can't be right. But transmission still works..

Thanks
