OLED Display
- On ebay...
- There are several versions
- MyMenu requires
- 4-pin I2C version
- Rev X1-X3 requires pin Ordering VCC, GND, SCL, SDA
I2C Connector
Rev X4 I2C Connector
The card has a 5-pin, 0.1" spacing connector. The connector has I2C connections (CLK and DATA) plus an Interrupt line.
- GND
- VCC
- SDA
- SCL
- INT
Rev X3 I2C Connector
- The card has a 5-pin, 0.1" spacing connector
- The connector has I2C connections (CLK and DATA) plus an Interrupt line
- Silkscreen is incorrect for SDA/SCL
- Pinout is
- GND

Arduino Libraries
- The Display library is decoupled from the MyMenu library and requires a separate install
MyMenu Card Library/Examples
- MyMenu library on GitHub
- Can download the ZIP file and use the ZIP library installer
- Card requires the Arduino Adafruit MCP23008 library
- Needs to be installed separately from the MyMenu library
- MCP23008 is the I2C interface chip that communicates with the buttons and LEDs
- Tested with Adafruit MCP23008 library version 1.0.1
- Driver is used to talk to the buttons/LEDs on the MyMenu card
- Driver can be installed from the Arduino IDE - search "Adafruit MCP23008"
- MyMenu card example code
Display Library - V2 Version
- V3 Version uses Oli Kraus' u8x8 library (part of u8g2 library)
- Oli Kraus' u8g2 OLED library
- Library can be installed through Arduino IDE
- Optional Land Board Menu System Code for OLED Displays - uses u8g2
- Sketch uses 8,354 bytes (25%) of program storage space. Maximum is 32,256 bytes.
- Global variables use 780 bytes (38%) of dynamic memory, leaving 1,268 bytes for local variables. Maximum is 2,048 bytes.
Display Library - Older Version (Deprecated)
- Oli Kraus' u8glib OLED library or
- Library can be installed through Arduino IDE
- Optional Land Board Menu System Code for OLED Displays - uses u8glib
- Sketch uses 10,958 bytes (33%) of program storage space. Maximum is 32,256 bytes.
- Global variables use 682 bytes (33%) of dynamic memory, leaving 1,366 bytes for local variables. Maximum is 2,048 bytes.
Other libraries - Not Recommended for New Designs
Driver/Example code
