Because this program is relatively simple, I will not explain it in detail. The hardware circuit will also be briefly explained in the source code.

See the source code:

 

 

#include                  //IO verbal file call

#include

#define uchar unsigned char         //declaration

#define uint unsigned int

uchar reg[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90,0xff};   //8-bit digital tube font encoding table

 

int main(void)

  DDRB = 0xff;     //These two lines indicate setting the IO register as output

  DDRC = 0xff;

  

  while(1)

  {

               PORTC = reg[0];    //display 0

               PORTB = 0xfe;       //The first digital tube lights up

     }

        }

I am also a novice in AVR. Please point out any deficiencies in the source program. I also hope that you can post some of your own programs and experiences to share with everyone.

The Linglong system post I am writing now was soldered by myself. Due to the need to constantly solder the hardware circuit, the update may be very slow.

I also hope that what I wrote can be of some help to friends who are new to AVR like me.

I also hope that everyone can join the Cepark Electronics Park family. After being here for so long, I feel that it is a very good place.
