Member Function Documentation

◆ beginI2C()

bool SPI_Interface::beginI2C ( uint8_t  address,
TwoWire &  wire,
uint32_t  speed,
uint8_t  sda,
uint8_t  scl 
)
inlineoverridevirtual

beginI2C()

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

Returns:

  • true → Initialization successful
  • false → Initialization failed

Implements Interface_7Semi.

◆ beginSPI()

bool SPI_Interface::beginSPI ( uint8_t  csPin,
SPIClass &  spiPort,
uint32_t  spiSpeed,
uint8_t  sck = 255,
uint8_t  miso = 255,
uint8_t  mosi = 255 
)
inlineoverridevirtual

beginSPI()

  • Initialize SPI interface
  • Configure CS and SPI bus

Implements Interface_7Semi.

Here is the caller graph for this function:

◆ read()

int8_t SPI_Interface::read ( uint8_t  reg,
uint8_t *  data,
uint32_t  len 
)
inlineoverridevirtual

read()

  • Read multiple bytes from register

Send register address (read)

Read data

Implements Interface_7Semi.

Definition at line 62 of file 7Semi_SPI_Interface.h.

◆ write()

int8_t SPI_Interface::write ( uint8_t  reg,
const uint8_t *  data,
uint32_t  len 
)
inlineoverridevirtual

write()

  • Write multiple bytes to register

Send register address (write)

Write data

Implements Interface_7Semi.
