Note
A button hold is different than a button press. A button press is applied for less than
1.5 seconds; a button hold is applied for more than 1.5 seconds. Hold the button down
to progress through the modes and tasks in the menu. A mode or task is not selected
until you follow a button hold with a button press.
Implementing an Operating Function
The following section contains a description of Mode 1 and Task A from the example code
at the end of this chapter (see Example Code 4.1 section).
Mode 1
Mode 1 begins with a setup function. In the example below, the setup function is called
Setup1 and will print the selections made to the menu.
void Setup1( void )
{
printf(“\n\nSetting up Mode 1...\n”);
printf(“Selection 1 (yellow bank) = %d \n”,
ClickMenuSelection1());
printf(“Selection 2 (red bank) = %d \n”,
ClickMenuSelection2());
printf(“Finished\n”);
}
The mode function will be called continuously after Setup1 returns. The mode function
(Mode1) prints “This is operating mode 1/n” in one second intervals.
