#define ACCEL_I2C_ADDRESS                      0x1C

#define i2c_DisableAck()    I2C0_C1 |= I2C_C1_TXAK_MASK

#define i2c_RepeatedStart() I2C0_C1 |= I2C_C1_RSTA_MASK;

#define i2c_Start()          I2C0_C1 |= I2C_C1_TX_MASK;\
                           I2C0_C1 |= I2C_C1_MST_MASK

#define i2c_Stop()          I2C0_C1 &= ~I2C_C1_MST_MASK;\
                           I2C0_C1 &= ~I2C_C1_TX_MASK

#define i2c_EnterRxMode()    I2C0_C1 &= ~I2C_C1_TX_MASK;\
                           I2C0_C1 &= ~I2C_C1_TXAK_MASK

#define i2c_Wait()             while((I2C0_S & I2C_S_IICIF_MASK)==0) {} \
                              I2C0_S |= I2C_S_IICIF_MASK;

#define i2c_write_byte(data) I2C0_D = data

#define MWSR                0x00  /* Master write  */
#define MRSW                0x01  /* Master read */

void init_I2C(void);
void IIC_StartTransmission (unsigned char SlaveID, unsigned char Mode);
void I2CWriteRegister(unsigned char u8RegisterAddress, unsigned char u8Data);
unsigned char I2CReadRegister(unsigned char u8RegisterAddress);
unsigned char I2CReadMultiRegisters(unsigned char u8RegisterAddress, unsigned char bytes);

我想问一下#define ACCEL_I2C_ADDRESS                      0x1C定义的是什么地址是从设备吗？
