UpdateTimeCounters() function is called every time and it corrects the values of every counter variable depending upon the value of msCounter, which is incremented in the ISR function of timer0 (shown below). After that, in the while(1) loop, whenever msCounter reaches a value of zero, then new values of hrCounter, minCounter and secCounter are updated on the LCD. Then Timer0 is initialized to generate 1msec interrupts. In the main function, firstly LCD is initialized using InitLCD() function. This process continues until hrCounter reaches 24 then all of these variables reset their values. LCD is updated with the new values of hrCounter, minCounter and secCounter after every second.Ī crystal of 4MHz value is used in this circuit, which makes this PIC16F84A run at a speed of 1MIPS (Million of instructions per second). And when minCounter reaches 60 then hrCounter increments. Similarly, when secCounter reaches 60, then minCounter increments. When msCounter reaches a value of 1000 then another global variable named secCounter increments and this process repeats itself. After every 1msec a global variable named msCounter increments. Timer0 is used here to generate 1msec interrupts. In the code, timer0 is used as the base for digital clock generation. The above figure was taken after 1 minute and 6 seconds of code simulation in Proteus. The result of simulating the code in Proteus is shown below.
