I reformatted the screen to show pairs of HEX values separated by spaces and noticed the incoming signals were limited to four or fewer pairs. The new format was easier to read than the one without spaces. I added code to check the switch statuses. The code monitored for rising and falling edges, and they both worked well.
I added the code for sending IR messages and tried to trigger it whenever I pressed the trigger. I could not tell if the tagger was sending codes properly, but when I looked at the LED with a night vision camera, the light was constantly illuminated. The suggested circuit showed a transistor, so I built the circuit on a breadboard, and it worked, so I installed it permanently. I tested the signal by recording the output with a Flipper and replaying it to the tagger, which showed the same code I sent. I added the transistor to the schematic.
