# Driver for I2C SSD1306 128x64 OLED LCD
|
|
|
|
This driver is written for usage with the ESP8266 and FreeRTOS ([esp-open-rtos](https://github.com/SuperHouse/esp-open-rtos)).
|
|
|
|
### Usage
|
|
|
|
Before using the SSD1306 LCD module, the function `i2c_init(SCL_PIN, SDA_PIN)` needs to be called to setup the I2C interface and then you must call ssd1306_init().
|
|
|
|
#### Example
|
|
|
|
```
|
|
#define SCL_PIN GPIO_ID_PIN(0)
|
|
#define SDA_PIN GPIO_ID_PIN(2)
|
|
...
|
|
|
|
i2c_init(SCL_PIN, SDA_PIN);
|
|
|
|
if (ssd1306_init()) {
|
|
// An error occured, while performing SSD1306 init init (E.g device not found etc.)
|
|
}
|
|
|
|
// rest of the code
|
|
```
