事实上，在C:StellarisWare_LatestdocsSW-DRL-UG-xxxx.pdf中每个模块后面，都有一段简单的代码示例可以参考。如I2C的部分，如下：

The following example shows how to use the I2C API to send data as a master.
//
// Initialize Master and Slave
//
I2CMasterInitExpClk(I2C_MASTER_BASE, SysCtlClockGet(), true);
//
// Specify slave address
//
I2CMasterSlaveAddrSet(I2C_MASTER_BASE, 0x3B, false);
//
// Place the character to be sent in the data register
//
I2CMasterDataPut(I2C_MASTER_BASE, ’Q’);
//
// Initiate send of character from Master to Slave
//
I2CMasterControl(I2C_MASTER_BASE, I2C_MASTER_CMD_SINGLE_SEND);
//
// Delay until transmission completes
//
while(I2CMasterBusBusy(I2C_MASTER_BASE))
{
}
