The YiChuang ET6001 development board has an RTC timing function. When using serial port 0 to connect an external USB to TTL module, the RTC timing effect can be viewed, as shown in Figure 2.

Figure 2 Test results

If RTC is combined with the serial digital tube display module, the timing effect of the electronic clock can be achieved. The main program is:

int main(void)
{
    rtcDatetime calendar;
    uint8_t tick = 0;
    RTC_Calendar_init();
    EVB_SMG_Init();
	Init_MAX7219();
    Write_Max7219(1,1);
    Write_Max7219(2,0);
	Write_Max7219(3,10);
    Write_Max7219(4,0);
    Write_Max7219(5,0);
    Write_Max7219(6,10);
    Write_Max7219(7,0);
    Write_Max7219(8,0);
    while (1)
    {
        RTC_GetDatetime(&calendar);
        if(tick != calendar.second)
        {
            tick = calendar.second;
		    Write_Max7219(1,calendar.second%10);
            Write_Max7219(2,calendar.second/10);
			Write_Max7219(4,calendar.minute%10);
            Write_Max7219(5,calendar.minute/10);
			Write_Max7219(7,calendar.hour%10);
            Write_Max7219(8,calendar.hour/10);
        }
    }
}

After compiling and running the program, the effect is shown in Figure 3.
