Ok, my Cyclone finally came in and I completed my OSSC. After spending an hour trying to find a basically invisible short on one of the 3.3v lines (thanks for the pictures of the PCB traces, they were very helpful!!!), my OSSC is working great!
I’ve now realized how stupidly easy it is to program the OSSC to the remote, so you’re right, this is basically useless! I just used my tv remote to find a code set that the OSSC responds to, then I used that to program my L336 remote button by button.
