Display Brightness Control & Admin UI Improvements

New Features

Display Brightness Control

  • Hardware brightness support: Direct AMOLED brightness control via RM67162 command (0x51), with a range of 0 (off) to 255 (maximum).
  • JavaScript API: New set_brightness(value) and get_brightness() functions available in JavaScript applications.
  • Serial command: New /brightness <0-255> serial command to set or query display brightness interactively.
  • Configuration persistence: Brightness is stored in webscreen.json under display.brightness and applied automatically on boot.
  • Default value: 200 (approximately 78% brightness).

Admin Tool UI

  • Real-time brightness slider: Adjusting the brightness slider in the Admin tool sends the change to the device immediately.

Configuration

Add brightness to your webscreen.json:

{
  "settings": {
    "wifi": {
      "ssid": "MyNetwork",
      "pass": "MyPassword"
    }
  },
  "display": {
    "brightness": 200
  },
  "script": "app.js"
}

JavaScript API Usage

// Set brightness
set_brightness(200);

// Read current brightness
let level = get_brightness();
print("Brightness: " + numberToString(level));

Serial Command Usage

WebScreen> /brightness
Current brightness: 200

WebScreen> /brightness 150
