Select 7SEG-MPX1-CC for the digital tube, a common cathode digital tube. That is, low level selection (rightmost pin), the 8 pins on the left side of the digital tube, from left to right, from low to high, are connected to PC0---PC7 respectively.
The c program is as follows:
#include
#include
#define int8u unsigned char
#define int16u unsigned int
const int8u seg_code[]={0x3f,0x06,0x5b,0x4f,0x66,0x6d,0x7d,0x07,0x7f,0x6f};
int main()
{
int8u i=0;
DDRC=0xff;
while(1)
{
PORTC=seg_code[i];
i=(i+1)%10; //When i increases to 10, reset to 0
_delay_ms(200);
}
}
