## Member Function Documentation

## ◆ beginI2C()

bool SPI_Interface::beginI2C | ( | uint8_t | address,
|  | TwoWire & | wire,
|  | uint32_t | speed,
|  | uint8_t | sda,
|  | uint8_t | scl
| ) |  |
| inline override virtual

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`
| ) |  |
| inline override virtual

beginSPI()

- Initialize SPI interface
- Configure CS and SPI bus

Implements Interface_7Semi.

Definition at line 21 of file 7Semi_SPI_Interface.h.

Here is the caller graph for this function:

## ◆ read()

int8_t SPI_Interface::read | ( | uint8_t | reg,
|  | uint8_t * | data,
|  | uint32_t | len
| ) |  |
| inline override virtual

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
| ) |  |
| inline override virtual

write()

- Write multiple bytes to register

Send register address (write)

Write data

Implements Interface_7Semi.
