Morse Code Input

Two taps on the desk is all it takes to send a command

Page 18 of 24 MCP / API open OTA updates

Enter Morse by tapping the device or the desk (recognised by the accelerometer); the screen shows the dot/dash sequence and the decoded character in real time, with a reference chart for common letters. The touch keys can also be used directly.

Recognition uses a double-tap counting scheme: a single tap is a dot, a second tap within 350 ms promotes it to a dash, and a 400 ms hold also counts as a dash; the character gap is 900 ms and the word gap 2700 ms. Thresholds adapt to the noise floor, so a still device produces no false triggers.

Key capabilities

🥁

Tap input

Single tap, double tap and long press combine into dots and dashes.

🔤

Live decoding

The dot/dash sequence appears as you tap and characters decode immediately.

📋

Reference chart

A chart of common letters stays on screen — no memorisation needed.

📶

Adaptive threshold

Resistant to ambient noise; even light taps register.

⚠ Boundaries & notes
  • Morse input suits short text and command triggers; for longer text use Bluetooth HID or the serial console.
