in this
On the PORT B .. LCD and SIX 7 Seg display DIGITs and 4x4 keypad is connected.. ( RB0-RB7 -- LCD , LCD_EN =AN2, and 4x4keypad and 7 seg(A-H))
I can use either LCD or 7 SEG display...(Common anode)
These 7 Seg Display is powered with PORTD which is through ULN 2003...
Here my function is to Use 7 Seg display to display any counted values..
using keypad i should increment/ decrement any value which should show on
7 Seg display (it may be 2 digit or 6 digit)..
If posible using EEPROM.. to store prev value..while incr/dec counter value.
