| Abstract: | RTC has a broad application prospect in the industrial real-time clock monitoring system . The system designed controls the RTC with LPC2131 microcontroller as the core, realizing the function of all kinds of time-register., second-register, minute-register, hour-register with accurate operations, and sends the collected data to PC through the UART. This paper proposes a design scheme, the overall block diagram of hardware design and software implementation methods. Experimental results are obtained. The method of controlling RTC is easy to apply to modern industry systems and a variety of intelligent application systems. |
