is the button DL the DIO0:40?
RE: KinCony ALR ESP32 I/O pin define - admin - 12-07-2024
DL button is GPIO0

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.
