I2CSPMKit Drivers

Detailed Description

I2C Simple Polled Master driver.

This driver supports master mode, single bus-master only. It blocks while waiting for the transfer is complete, polling for completion in EM0.

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.
