2025-10-21 (Tu) BonfireLaserTag Transmitting the settings over IR

The most important thing the taggers have to do is transmit and receive data from one unit to another. I powered two taggers and verified that I could receive a modified signal from the other. I could monitor this way, but it was a hassle, so I removed the second tagger and used a Flipper to record and retransmit it back to the first. Using the Flipper, I was able to keep one gun connected to the computer and read the signal it transmitted. I wanted to transmit the signal as three bytes: serial number, team, and damage. I had to put them into one unsigned long, so I multiplied serial by 0xFFFF, team by 0xFF, and added the damage code. This math worked, except for the damage code which was always wrong. I kept experimenting and discovered that I should have been multiplying by 0x10000 and 0x100. Once I corrected the calculations, the transmissions worked reliably. I set limits on the serial number (0-15), team (1-15), and damage (1-100).
