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.
