@ -31,9 +31,33 @@ This usermod requires the `U8g2` and `Wire` libraries. See the
`platformio_override.ini.sample` found in the Rotary Encoder `platformio_override.ini.sample` found in the Rotary Encoder
UI usermod folder for how to include these using `platformio_override.ini`. UI usermod folder for how to include these using `platformio_override.ini`.
## Configuration
* `enabled` - enable/disable usermod
* `pin` - GPIO pins used for display; I2C displays use Clk & Data; SPI displays can use SCK, MOSI, CS, DC & RST
* `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)
* `contrast` - set display contrast (higher contrast may reduce display lifetime)
* `refreshRateSec` - time in seconds for display refresh
* `screenTimeOutSec` - screen saver time-out in seconds
* `flip` - flip/rotate display 180°
* `sleepMode` - enable/disable screen saver
* `clockMode` - enable/disable clock display in screen saver mode
* `i2c-freq-kHz` - I2C clock frequency in kHz (may help reduce dropped frames, range: 400-3400)
## Change Log ## Change Log
