Synaptic A220 | WinCtrl RMP | MobiFlight Profile (COM1 + Squawk)

This add-on provides a MobiFlight profile for integrating the Synaptic A220 with the Winwing WinCtrl RMP (left unit). It enables COM1 standby frequency management with 8.33 kHz spacing, VHF transmit-select buttons and LEDs, and a transponder squawk code editor using the LOAD button. The profile also supports pedestal-lighting-linked backlighting but does not map HF, NAV, or related buttons not available in the A220 SDK. Installation requires MobiFlight BETA and setup through the "From Existing Project" option.
