WebAn array numhr is used to store the values from 81 to 92. When RTC sends the output, microcontroller reads hours and if it matches with any of the numhr variable it displays corresponding value from nummin array else it displays the same value for hours. This trick is used to convert the RTC from 24 hour mode to 12 hour mode. WebReal time clock (RTC) is widely used in many application to provide accurate time. This article explains the making of a simple digital clock using RTC DS12C887 and 8051 microcontroller ( AT89C51 ). The output is displayed on an LCD. This clock also has a provision of setting time at any instant.
