I2C通信使用中断

嗨JE_Dialog,

你能给我一份使用中断的I2C通信的文档吗?
如果没有正式文件，你可以帮我回答以下问题:
1.如何使I2C中断模式运行?(主模式)
2.如何读取I2C通信状态码?
3.请告诉我在主发射机和接收机模式下的格式和状态。
4.请给我一个这样的示例代码:

空白I2C_IRQHandler(空白)
｛
uint8_t StatValue;

超时= 0;
/*这个处理程序只处理主读和主写
StatValue = LPC_I2C - >统计;
switch (StatValue)
｛
case 0x08: /*触发启动条件。＊／
WrIndex = 0;
LPC_I2C - > DAT = I2CMasterBuffer (WrIndex + +);
Lpc_i2c -> conclr = (i2conclr_sic | i2conclr_stac);
打破;

case 0x10: /* A repeated started is issued */
RdIndex = 0;
/*发送设置R位的SLA， */
LPC_I2C - > DAT = I2CMasterBuffer (WrIndex + +);
Lpc_i2c -> conclr = (i2conclr_sic | i2conclr_stac);
打破;

case 0x18: /*无论如何，它是一个ACK */
if (I2CWriteLength == 1)
｛
LPC_I2C - > CONSET = I2CONSET_STO;/*设置停止标志*/
I2CMasterState = I2C_NO_DATA;
｝
其他的
｛
LPC_I2C - > DAT = I2CMasterBuffer (WrIndex + +);
｝
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

case 0x28: /* Data byte has been sent, regardless of ACK or NACK */
if (WrIndex < I2CWriteLength)
｛
LPC_I2C - > DAT = I2CMasterBuffer (WrIndex + +);/*这应该是最后一个*/
｝
其他的
｛
if (I2CReadLength != 0)
｛
LPC_I2C - > CONSET = I2CONSET_STA;/*设置重复开始标志*/
｝
其他的
｛
LPC_I2C - > CONSET = I2CONSET_STO;/*设置停止标志*/
I2CMasterState = I2C_OK;
｝
｝
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

例0 x30:
LPC_I2C - > CONSET = I2CONSET_STO;/*设置停止标志*/
I2CMasterState = I2C_NACK_ON_DATA;
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

case 0x40: /* Master Receive, SLA_R has been sent */
if ((RdIndex + 1) < I2CReadLength)
｛
/*将进入状态0x50 */
LPC_I2C - > CONSET = I2CONSET_AA;/*在收到数据后断言ACK */
｝
其他的
｛
/*将进入状态0x58 */
LPC_I2C - > CONCLR = I2CONCLR_AAC;/*收到数据后断言NACK */
｝
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

case 0x50: /* Data byte has been received，不管后面是ACK还是NACK */
I2CSlaveBuffer [RdIndex + +] = LPC_I2C - > DAT;
if ((RdIndex + 1) < I2CReadLength)
｛
LPC_I2C - > CONSET = I2CONSET_AA;/*在收到数据后断言ACK */
｝
其他的
｛
LPC_I2C - > CONCLR = I2CONCLR_AAC;/* assert NACK on last byte */
｝
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

例0 x58:
I2CSlaveBuffer [RdIndex + +] = LPC_I2C - > DAT;
I2CMasterState = I2C_OK;
LPC_I2C - > CONSET = I2CONSET_STO;/*设置停止标志*/
LPC_I2C - > CONCLR = I2CONCLR_SIC;/*清除SI标记*/
打破;

case 0x20: /*无论如何，它是一个NACK */
例0 x48:
LPC_I2C - > CONSET = I2CONSET_STO;/*设置停止标志*/
I2CMasterState = I2C_NACK_ON_ADDRESS;
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;

case 0x38: /*仲裁失败，在这个例子中，我们没有
处理多个主情况*/
默认值:
I2CMasterState = I2C_ARBITRATION_LOST;
LPC_I2C - > CONCLR = I2CONCLR_SIC;
打破;
｝
返回;
｝

最好的问候,
