Garbage In, Pearls Out?
summary
Builds a working IR pass through for a distributed audio system that turns noisy, low‑quality remote captures into reliable commands by detecting leader pulses, generating an on the fly protocol, then interpreting and replaying only the decoded data so output matches the ideal timings. Uses a PIC18F microcontroller, ARM Linux devices, oscilloscope and cheap logic recorders with PulseView, C code and timing buckets and averaging, plus UI tweaks and backlight smoothing. Result often works better than pointing the remote directly.
