* invert inputs * move RFID RX to IRQ, unstable * remove critical blink * supress short carrier, decrease queue * migrate to stream buffer * enable state change * conditions build for invert RFID IN * move get_rfid_in_level * use hal function for get comp level, remove duplicate interrupt registration, interrupt unregister on exit * reinit comparator context on mode change
