Member Function Documentation

◆ init()

void miosix::I2C1Driver::init ( )

Initializes the peripheral. The only supported mode is 100KHz, master, 7bit address. Note that there is no need to manually call this member function as the constructor already inizializes the I2C peripheral. The only use of this member function is to reinitialize the peripheral if the microcontroller clock frequency or the APB prescaler is changed.

◆ instance()

I2C1Driver & miosix::I2C1Driver::instance ( )

static

Returns: an instance of this class (singleton)

Definition at line 195 of file stm32f2_f4_i2c.cpp.

◆ recv()

bool miosix::I2C1Driver::recv	(	unsigned char	address,
		void *	data,
		int	len )

Receive data from a device connected to the I2C bus

Parameters

address	device address (bit 0 is forced at 1)
data	pointer to a buffer where data will be received
len	length of data to receive

Returns: true on success, false on failure

Definition at line 359 of file stm32f2_f4_i2c.cpp.

◆ send()

bool miosix::I2C1Driver::send	(	unsigned char	address,
		const void *	data,
		int	len,
		bool	sendStop = true )

Send data to a device connected to the I2C bus

Parameters

address	device address (bit 0 is forced at 0)
data	pointer with data to send
len	length of data to send
sendStop	if set to false disables the sending of a stop condition after data transmission has finished

Returns: true on success, false on failure
