The scheme of counting button clicks with the output of the number of clicks on the seven-segment indicator (up to 99 clicks)

[microlab_rcr]

Hello, i have a problem with this task, i dont understand how to display numbers on a seven-segment indicator after 10. I understand that you need to quickly switch the state of the common anode of each indicator, but I can't imagine how to write it in the program, maybe you will give some advice. I attached the code mikroC and scheme from Proteus.

Here's the c code from archive:

/* The scheme of counting button clicks with the output of the number of clicks on the seven-segment indicator (up to 99 clicks) */

int count = 0; //counter
int razr;
bit oldstate; //button state
char seg[]={0xc0,0xf9,0xa4,0xb0,0x99,0x92,0x82,0xf8,0x80,0x90}; //7seg digits

void setup() // setip i/o
{
 TRISB = 0;
 TRISD.RD0 = 0;
 TRISD.RD1 = 0;
 TRISD.RD2 = 1;
 PORTD.RD0 = 0;
 PORTD.RD1 = 0;
 PORTB = 0;
}


void setMode(int c) //*
{
 if (c < 10)
 {
  delay_ms(20);
  PORTD.RD1 = 1;
  PORTB = seg[c%10];
 }
 if (c >= 10)
 {
  PORTD.RD0 = 1;
  PORTB = seg[(c/10)%10];
 }
}

void main()
{
 setup();
 while(1)
 {
  if (Button (&PORTD, 2, 5, 1))//Debouncing
  {
   oldstate = 1; //flag button state
  }
  if (oldstate && Button (&PORTD, 2, 5, 0))
  {
   count++;
   oldstate = 0;
  }
  if (count == 100)
  {
   count = 0;
  }
  setMode(count);
 }
}

Please don't presume that EDAboard users are working with Proteus, better post a schematic print.

Oh sorry, thanks for advice)

This can be done in HW, how many digits ?

An example (posts 6 and 8)
