//go:build xiao_ble

// This initializes SSD1306 OLED display driver over I2C.
//
// Seeed XIAO BLE board + SSD1306 128x32 I2C OLED display.
//
// Wiring:
// - XIAO GND      -> OLED GND
// - XIAO 3v3      -> OLED VCC
// - XIAO D4 (SDA) -> OLED SDA
// - XIAO D5 (SCL) -> OLED SCK
//
// For your case:
// - Connect the display to I2C pins on your board.
// - Adjust I2C address and display size as needed.
