PPM-dat
PPM (Pulse Position Modulation) is a type of analog signal used in radio control (RC) systems to transmit multiple channels of control information (like throttle, steering, elevator, etc.) over a single wire.
In simple terms:
- It sends a series of pulses.
- The position (or timing) of each pulse within a repeating frame represents the value for a specific channel.
- A longer "sync" pulse marks the end of one frame and the beginning of the next.
So, instead of needing a separate wire for each control channel, PPM combines them into one sequential signal.
