Member Function Documentation

beginI2C()

virtual bool Interface_7Semi::beginI2C ( uint8_t  address, TwoWire &  wire, uint32_t  speed, uint8_t  sda = 255, uint8_t  scl = 255  )

pure virtual

beginI2C()

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

Returns:

• true → Initialization successful
• false → Initialization failed

Implemented in I2C_Interface, and SPI_Interface.

beginSPI()

virtual bool Interface_7Semi::beginSPI ( uint8_t  cs_pin, SPIClass &  wire, uint32_t  speed, uint8_t  csk = 255, uint8_t  miso = 255, uint8_t  mosi = 255  )

pure virtual

Implemented in SPI_Interface, and I2C_Interface.

delay_us()

static void Interface_7Semi::delay_us ( uint32_t  us )

inlinestaticprotected

Delay wrapper

Definition at line 82 of file 7Semi_Interface.h.

read()

virtual int8_t Interface_7Semi::read ( uint8_t  reg, uint8_t *  data, uint32_t  len  )

pure virtual

read()

• Reads data from device register

Parameters:

• reg : Register address
• data : Output buffer
• len : Number of bytes

Returns:

• 0 → Success
• <0 → Error

Implemented in I2C_Interface, and SPI_Interface.

write()

virtual int8_t Interface_7Semi::write ( uint8_t  reg, const uint8_t *  data, uint32_t  len  )

pure virtual

write()

• Writes data to device register

Returns:

• 0 → Success
• <0 → Error

Implemented in I2C_Interface, and SPI_Interface.
