ولكن أتمنى منك ان تشرح لنا كيف يمكننا زيادة العداد لكي يعد الى المليون

أخى الكريم
شكرا جزيلا لك
بارك الله فيك
أشكرك على الاستفسار
التعديل للوصول إلى المليون أو ما بعد المليون سهل للغاية وسوف يثبت بعض اسس البرمجة بلغة السى :
فى البداية البرنامج الأول :

' Alphanumeric LCD and Push Button.
' Description:
' In this experiment we will work with alphanumeric LCD and push button.
' Communication with LCD will be performed through 4-bits and connections
' is made as follows: D4 with RD, D5 with RD4, D6 with RD6, D7 with RD7;
' RS with RD0 and EN with RD1.
' The Push button is connected to PORT RC0 (for increment) and PORT RC1
' (for decrement). Of course both button have pull-up resistors (4k7).
' To make this project more interesting , you can reach from 0000 to 9999
' by pressing the button.
' Test configuration:
' MCU: PIC16F877A
' SW: MikroC PRO

إذا تتبعنا البرنامج نجد أننا نحتاج إلى تغيير :
1- المتغير
كود:
unsigned int number = 0;
صالح فقط حتى 65535 ومن ثم يجب تغييره إلى المتغير :
كود:
unsigned long number = 0;
وهوصالح حتى 4294967295 .
2- توسعة مدى متغير مصفوفة السلسلة النصية :
كود:
char *digit = "0000";
لتتسع للملايين :
كود:
unsigned long number = 0;
char *digit = "0000000";
3- توسعة أستخراج الخانات من الألوف :
كود:
void Display_init() // define display_init;
{
digit[0] = number/1000 + 48; // thousands digit;
digit[1] = (number/100)%10 +48; // hundreds digit;
digit[2] = (number/10)%10 + 48; // tens digit;
digit[3] = number%10 +48; // unit digit;
Lcd_Out(2,7,digit); // display on LCD from column 2, character 7;
}
لتتسع للملايين :
كود:
000";
void Display_init() // define display_init;
{
/*
digit[0] = number/1000 + 48; // thousands digit;
digit[1] = (number/100)%10 +48; // hundreds digit;
digit[2] = (number/10)%10 + 48; // tens digit;
digit[3] = number%10 +48; // unit digit;*/
digit[0] = number/1000000 + 48;
digit[1] = (number/100000)%10 + 48;
digit[2] = (number/10000)%10 + 48;
digit[3] = (number/1000)%10 +48;
digit[4] = (number/100)%10 +48;
digit[5] = (number/10)%10 +48;
digit[6] = number%10 +48;
Lcd_Out(2,7,digit); // display on LCD from column 2, character 7;
}
هذا كل ما هنالك .

وما زال العد فى ازدياد
