Function Documentation

void I2CSPM_Init

(

I2CSPM_Init_TypeDef *

init

)

Initalize I2C peripheral.

This driver supports master mode only, single bus-master. In addition to configuring the I2C peripheral module, it also configures DK/STK specific setup in order to use the I2C bus.

Parameters

[in]

init

Pointer to I2C initialization structure

I2C_TransferReturn_TypeDef I2CSPM_Transfer	(	I2C_TypeDef *	i2c,
		I2C_TransferSeq_TypeDef *	seq
	)

Perform I2C transfer.

This driver only supports master mode, single bus-master. It does not return until the transfer is complete, polling for completion.

Parameters

[in]	i2c	Pointer to the peripheral port
[in]	seq	Pointer to sequence structure defining the I2C transfer to take place. The referenced structure must exist until the transfer has fully completed.
