| Abstract: | This paper introduces a real-time clock and temperature detection system of ESR analyzer with the SMBus bus technology and 1-wire bus technology. C8051F microprocessor is used as main controller. The system uses a calendar clock chip PCF8563 with I2C interface to offer time and a programmable resolution 1-wire digital thermometer to detect temperature. The data are real-time displayed in LCD. This system has features of simple structure, low power consumption, good reliability and powerful transplantable ca... |
