  • Speed
  • Intensity
  • Palette
  • Effect
  • Main Color
  • Saturation

Press and hold the encoder to display Network Info. If AP is active, it will display the AP, SSID and Password

See the pair of usermods in action

Installation

Copy the example platformio_override.sample.ini to the root directory of your particular build.

Configuration

These options are configurable in Config > Usermods

Usermod Setup

  • Global I2C GPIOs (HW) - Set the SDA and SCL pins

4LineDisplay

  • enabled - enable/disable usermod
  • type - display type in numeric format
    • 1 = I2C SSD1306 128x32
    • 2 = I2C SH1106 128x32
    • 3 = I2C SSD1306 128x64 (4 double-height lines)
    • 4 = I2C SSD1305 128x32
    • 5 = I2C SSD1305 128x64 (4 double-height lines)
    • 6 = SPI SSD1306 128x32
    • 7 = SPI SSD1306 128x64 (4 double-height lines)
    • 8 = SPI SSD1309 128x64 (4 double-height lines)
    • 9 = I2C SSD1309 128x64 (4 double-height lines)
  • pin - GPIO pins used for display; SPI displays can use SCK, MOSI, CS, DC & RST
  • flip - flip/rotate display 180°
  • contrast - set display contrast (higher contrast may reduce display lifetime)
  • screenTimeOutSec - screen saver time-out in seconds
  • sleepMode - enable/disable screen saver
  • clockMode - enable/disable clock display in screen saver mode
  • showSeconds - Show seconds on the clock display
  • i2c-freq-kHz - I2C clock frequency in kHz (may help reduce dropped frames, range: 400-3400)

PlatformIO requirements

Note: the Four Line Display usermod requires the libraries U8g2 and Wire.
