Function Documentation

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]i2cPointer to the peripheral port
[in]seqPointer to sequence structure defining the I2C transfer to take place. The referenced structure must exist until the transfer has fully completed.

Definition at line 124 of file i2cspm.c.
