is the button DL the DIO0:40?

[admin]

DL button is GPIO0

[maso]

THis is correct & tested
#define IO0 0 //DL Button

Hello admin,

I am using the KinCony KC868-A6v3 board and developing custom firmware with Arduino / PlatformIO.

The SSD1306 OLED works with the factory firmware, but when I upload my own firmware the LCD stays blank.

Could you please tell me:

What GPIO pins are used for the OLED I2C (SDA / SCL)?

What is the I2C address (0x3C or 0x3D)?

Do we need to initialize any IO expander or controller before using the OLED?

Do you have a simple Arduino example to initialize the onboard OLED?

Thank you.
