I2C 4 Line Display Usermod

First, thanks to the authors of the ssd11306_i2c_oled_u8g2 mod.

This usermod provides a four line display using either 128x32 or 128x64 OLED displays. It's can operate independently, but starts to provide a relatively complete on-device UI when paired with the Rotary Encoder UI usermod. I strongly encourage you to use them together.

See the pair of usermods in action

Installation

Copy and update the example platformio_override.ini.sample from the Rotary Encoder UI usermode folder to the root directory of your particular build. This file should be placed in the same directory as platformio.ini.

Define Your Options

USERMOD_FOUR_LINE_DISPLAY - define this to have this the Four Line Display mod included wled00\usermods_list.cpp - also tells Rotary Encoder usermod, if installed, that the display is available
FLD_PIN_SCL - The display SCL pin, defaults to 5
FLD_PIN_SDA - The display SDA pin, defaults to 4

All of the parameters can be configured using Usermods settings page, inluding GPIO pins.

PlatformIO requirements

This usermod requires the U8g2 and Wire libraries. See the platformio_override.ini.sample found in the Rotary Encoder 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)
