This is so annoying… My core is still not getting any MidiIn. I went thru the entire troubleshooting guide. Everything worked as described, but I still don’t get any input.
I tried different 18Fs with the Bootloader on it. I get the upload request. Everything fine so far. The opto coupler is definately ok, too. I tested it with the opto test “board”.
All components are in place and ok. The Midi sockets are ok and wired correctly.
I cannot seem to find any problem. Still the MidiIn is not working appararently.
That’s cool. It’s not like it your fault. ;) As I said, I must be missing something horribly obvious. ??? I’ll get another board on Monday, so I’ll try that one and if it works (it hopefully will) I’ll have something to compare.
I did miss something. I whipped my magnifying glass out and checked all connections again. And guess what. There was a tiny blob of soldering tin (about 0.5mm in diameter) stuck (not soldered) between the jumpers and the line to R2. Got it out and - tada - it’s working! Thanks for all your help ;D
It was not even a soldering problem really. It was just a tiny ball of tin that got stuck there. It wasn’t even soldered onto the board. I was just sitting there And if I hadn’t accidentally found my magnifiying glass I’d never have found it. Strange. Thanks anyways!
