void I2C_EE_WaitEepromStandbyState(void)
{
vu16 SR1_Tmp = 0;
do
{
/* Send START condition */
I2C_GenerateSTART(I2C1, ENABLE);
/* Read I2C1 SR1 register */
SR1_Tmp = I2C_ReadRegister(I2C1, I2C_Register_SR1);
/* Send EEPROM address for write */
I2C_Send7bitAddress(I2C1, EEPROM_ADDRESS, I2C_Direction_Transmitter);
}while(!(I2C_ReadRegister(I2C1, I2C_Register_SR1) & 0x0002));
/* Clear AF flag */
I2C_ClearFlag(I2C1, I2C_FLAG_AF);
}
这段程序的作用是 Wait for EEPROM Standby state，
谁能给讲讲这里的原理，
这里只有开始条件，没有结束条件，为什么？？ |
