Member Function Documentation

beginI2C()

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

inlinevirtual

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 I2C_Interface::beginSPI ( uint8_t , SPIClass & , uint32_t , uint8_t , uint8_t , uint8_t  )

inlineoverridevirtual

Implements Interface_7Semi.

Definition at line 69 of file 7Semi_I2C_Interface.h.

read()

int8_t I2C_Interface::read ( uint8_t reg, uint8_t * data, uint32_t len )

inlineoverridevirtual

read()

• Reads data from device register

Parameters:

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

Returns:

• 0 → Success
• <0 → Error

Implements Interface_7Semi.

Definition at line 32 of file 7Semi_I2C_Interface.h.

write()

int8_t I2C_Interface::write ( uint8_t reg, const uint8_t * data, uint32_t len )

inlineoverridevirtual

write()

• Writes data to device register

Returns:

• 0 → Success
• <0 → Error

Implements Interface_7Semi.
