使用的是S08DZ60，硬件连接是不是直接把SDA，SCL分别接起来就可以了？ void configureI2C(unsigned char selfAddress){ IICF = 0x8D; /* Set IIC frequency */
IICC1_IICEN = 1; /* Enable IIC */
IICA = selfAddress; /* IIC Address */
I2C_STEP = IIC_READY_STATUS;
IICC1_IICIE = 1; /* Enable IIC interrupts */
} void WriteBytesI2C (unsigned char slaveAddress,unsigned char numberOfBytes){
unsigned char Temp;
slaveAddress &= 0xFE; /* Format the Address to fit in the IICA register and place a 0 on the R/W bit.*/
IICC1_IICEN = 0;
IICC1_MST = 0;
IICS_SRW = 0;
IICC1_TX = 1; /* Select Transmit Mode */
IICC1_MST = 1; /* Select Master Mode (Send Start Bit) */
IICC1_IICEN = 1;
Temp = IICS; /* Clear any pending interrupt */
IICS_IICIF=1;
for(Temp=0;Temp<10;Temp++); /* Small delay */
IICD = slaveAddress; /* Send selected slave address */ 不知道为什么，IICD的值总是0，一直不变
} void main(void) { MCU_init();
configureI2C(0x50);
I2C_DATA[0]='A'; /* test data */
EnableInterrupts; /* enable interrupts */
WriteBytesI2C(0x52,1); //对一个I2C写入
/* Application is based on interrupts so just stay here forever. */
for(;;) {
__RESET_WATCHDOG(); /* feeds the dog */
} /* loop forever */
/* please make sure that you never leave this function */
}
