ll_i2c_get_slave_address()

__STATIC_INLINE uint32_t ll_i2c_get_slave_address

(

i2c_regs_t *

I2Cx

)

Get the slave address programmed for transfer (master mode).

Register	BitsName
IC_TAR	TAR_ADDR

Parameters

I2Cx	I2C instance.

Return values

Value

between 0x0 and0x3F

ll_i2c_get_transfer_direction()

__STATIC_INLINE uint32_t ll_i2c_get_transfer_direction

(

i2c_regs_t *

I2Cx

)

Indicate the value of transfer direction (slave mode).

Note

RESET: Write transfer, Slave enters in receiver mode. SET: Read transfer, Slave enters in transmitter mode.

Register	BitsName
IC_RAW_INTR_STAT	INTR_RD_REQ
IC_RAW_INTR_STAT	INTR_RX_FULL

Parameters

I2Cx	I2C instance.

Return values

Returned

value can be one of the following values: LL_I2C_DIRECTION_WRITE LL_I2C_DIRECTION_READ

ll_i2c_handle_transfer()

__STATIC_INLINE void ll_i2c_handle_transfer	(	i2c_regs_t *	I2Cx,
		uint32_t	slave_addr,
		uint32_t	slave_addr_size
	)

Handles I2Cx communication when starting transfer or during transfer (TC or TCR flag are set).

Note

The register IC_CON and IC_TAR can only be programmed when the I2C is disabled (ENABLE = 0).

Register	BitsName
IC_CON	CON_10BITADDR_MST
IC_TAR	TAR_ADDR

Parameters

I2Cx	I2C instance.
slave_addr	Specifies the slave address to be programmed.
slave_addr_size	This parameter can be one of the following values: LL_I2C_ADDRESSING_MODE_7BIT LL_I2C_ADDRESSING_MODE_10BIT

Note

SlaveAddrSize in IC_CON register can only be programmed when the I2C is disabled (IC_ENABLE = 0).

Return values

None.

ll_i2c_receive_data8()

__STATIC_INLINE uint8_t ll_i2c_receive_data8

(

i2c_regs_t *

I2Cx

)

Read Receive Data register.

Register	BitsName
IC_DATA_CMD	DAT

Parameters

I2Cx	I2C instance.

Return values

Value

between Min_Data=0x00 and Max_Data=0xFF

ll_i2c_set_slave_address()

__STATIC_INLINE void ll_i2c_set_slave_address	(	i2c_regs_t *	I2Cx,

	)

Configure the slave address for transfer (master mode).

Note

The register IC_TAR can only be programmed when the I2C is disabled (ENABLE = 0).

Register	BitsName
IC_TAR	TAR_ADDR

Parameters

I2Cx	I2C instance.
slave_addr	This parameter must be a value between 0x00 and 0x3F.

Return values

None.

ll_i2c_transmit_data8()
