Member Function Documentation

◆ beginI2C()

bool I2C_Interface::beginI2C ( uint8_t  address,
TwoWire &  wire,
uint32_t  speed,
uint8_t  sda = 255,
uint8_t  scl = 255 
)

beginI2C()

  • Initializes I2C peripheral
  • Configures SDA / SCL pins if supported
  • Sets communication clock

Returns:

  • true → Initialization successful
  • false → Initialization failed

Implements Interface_7Semi.
