I want to create a user interface using C programming for a pic microcontroller-see attached picture.
It will have 3 pushbutton switches. It will allow the user to enter a 2 digit value:
1.enter/settings switch
2.increase digit from 0 to 9
3.decrease digit from 9 to 0
If the user pushes the settings button then the user will go to a settings screen. The user can then select a 2 digit value EG. 99 or 34. The user can use the increase button to increase the first digit from 0 to 9 and 0 to 9 again. The first digit will be displayed on the LCD whilst the user is increasing. Thereafter the user can use the decrease button to decrease the second digit from 9 to 0 and 9 to 0 again. The second digit will be displayed on the LCD whilst the user is decreasing. So now the user has decided on a 2 digit value and wants to use this value in another function so the user presses ENTER and leaves the Settings screen.
Any1 with any useful ideas to approach this.

Rich (BB code):
main()
{
int i;
TRISB= 0xFF;
i=0;
j=9;
while (1) {
//wait for press
while (RB6); // loop (1)
DelayMs (30); //debounce
//wait for release
while (!RB6); //loop(2)
DelayMs(30); //debounce
i++;
//wait for press
while (RB4); // loop (1)
DelayMs (30); //debounce
//wait for release
while (!RB4); //loop(2)
DelayMs(30); //debounce
j--;
