RC Transponder
Updated firmware for Chronelec RC transponder. This firmware addresses multiple operational issues with manufacturer-supplied transponders, particularly for use at the DISC Velodrome.
Features
- Battery level reporting: 1=OK, 2=Low Battery, 3=Fault
- LF sensitivity is maintained during transmit sequence
- Tx dead times are eliminated
- Prolonged activation suppresses Tx only while held in loop
- Periodic (270s) wakeup/reset is eliminated - transponder will sleep indefinitely, waking only for valid activation or error condition flagged by AFE
- Pseudorandom delays are distributed in ~2ms steps from 8 to 22ms, and the back-off timer is no longer used
- Initial collisions due to concurrent wake-ups are reduced
