Nucleo-F334 and OLED display

This is an example of connecting a 128×64 I2C OLED display to a NUCLEO-F334R8.

Vcc – 3.3v
Gnd – Any Gnd
SDA – D14
SCL – D15

here is a picture of the OLED I used, there are many variants of this available

Now for the breadboard layout

Code

This example requires the Adafruit_Gfx library to be imported into your project. Since this is an I2C display and its a 128×64 I had to modify the rawHeight parameter in the Adafruit_SSD1306.h code as follows

Here is an export of the code and libraries

Nucleo_OLED_zip_nucleo_f334r8

Adafruit_SSD1306_I2c(I2C &i2c, PinName RST, uint8_t i2cAddress = SSD_I2C_ADDRESS, uint8_t rawHeight = 32, uint8_t rawWidth = 128)

to

Adafruit_SSD1306_I2c(I2C &i2c, PinName RST, uint8_t i2cAddress = SSD_I2C_ADDRESS, uint8_t rawHeight = 64, uint8_t rawWidth = 128)

#include "mbed.h"
#include "Adafruit_SSD1306.h"
 
DigitalOut myLed(LED1);
I2C i2c(I2C_SDA, I2C_SCL);
 
Adafruit_SSD1306_I2c oled (i2c, D4);
 
int main() 
{
int tickTime = 1000;
oled.begin(SSD1306_SWITCHCAPVCC);
wait_ms(200);
oled.splash();
oled.display();
wait(2);
while(1) 
{
myLed = !myLed;
wait_ms(tickTime);
}
}

You should see the adafruit logo on your display if everything works OK
