Abstract: The realizing method of systemic interface within 1-wire temperature sensor DS18B20 and ATmega8 MCU have been introduced, the key point of source program delayed by μs grade programmed in embedding C language and operating diagram for DS18B20 has been given in this text. Some skills and problems needed to pay attention to while making use of C language to realize the method of the systemic interface software has been introduced also.
