viewegu Hello, try the common SSD1306 driver for 128x64 OLED, which is included in some examples.You need to select SDA on 4 and SCL on 15. This board has an additional reset connection on GPIO 16. If the level is low, the OLED is not working.I added gpio_set_direction(OLED_RESET_GPIO, GPIO_MODE_DEF_OUTPUT ); gpio_set_level(OLED_RESET_GPIO, 1); vTaskDelay(50/portTICK_RATE_MS); gpio_set_level(OLED_RESET_GPIO, 0); vTaskDelay(50/portTICK_RATE_MS); gpio_set_level(OLED_RESET_GPIO, 1);
