SSD1306I2C Oled Display is available on different internet store, see for example here and here.

The Datasheet is here.


We developed a simple test program using the NUCLEO-L053R8 and SSD1306.
The schematic is below.

Some extra info concerning this software

We used the CUBE-MX for generate the MCU configuration for KEIL.
Then we inserted the library for drive the SSD1306 Oled I2C display.
In the OLED library there is some include and I2C name that are:
#include “stm32l0xx_hal.h
In the main.c there is the define:
I2C_HandleTypeDef hi2c1;
so in the OLED library we use the same name to refer to the I2C port that is hi2c1

If you need use another NUCLEO board the suggestion is:
Generate your project using the CUBE-MX and next insert in your project the OLED library.
Next change in the OLED library the:
#include “stm32l0xx_hal.h
and
hi2c1
according to your project.

Last but not least, remember to control the file:
stm32l0xx_hal_msp.c
The name of file change in according to STM32 family that you use.
