# Walksnail Ascent VRX UART Protocol

> Walksnail Ascent VRX UART Protocol documents serial control messages for Walksnail video receivers and supplies a C reference transmitter with an STM32 example. It specifies framing, payload checksums, remote keys, channel selection and status queries, while recording contradictions and unknown reply layouts.

## Requirements & limits

- **Prerequisites:** A Walksnail VRX and a controller with a compatible UART interface for hardware use.
- **Limits:** The library limits payloads to 64 bytes; baud rate, electrical levels and pinout need hardware confirmation.
- **Testing evidence:** TX examples are tested against supplied documentation; RX telemetry layout and device behavior remain unresolved.
- **License:** MIT license.
