Description: DS1624 is due to the structure of I2C bus serial data transmission, it requires SDA and SCL completed two lines of data transmission process. Therefore, we design procedures during the time, it has agreed to subscribe for I2C chip DS1624 data access. The I2C agreement refer to the relevant information, will not elaborate here. For AT89S51 SCM does not I2C hardware resources, Therefore, we must use the software to simulate the process I2C agreement. Read from the DS1624 temperature, to start the internal temperature DS1624 A/D conversion start, corresponds to a corresponding order to start the starting temperature conversion, the DS1624 instruction set reference to the previous description. Under normal circumstances, the DS1624 temperature through a transformation takes a second time aro
