Hi Lofna,Thank you for posting your question online.Unfortunately, I do not think we have an OLED display example available for DA14531. I believe you can find drivers online for SSD1306 display. You can follow their logic and use our I2C APIs to implement them inside DA14531 platform. I will keep searching internally if we find any examples using OLED display (I2C). If I find anything I will update you here.Kind Regards,OV_Renesas
