Dear all.
I am trying to call Display menu. If up key is pressed Displayed has to be incremented and stay in particular window if Decremented, go to previous Display function and show previous Display function.
#include <LiquidCrystal.h>
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
static int button_counter=0;
#define btnRIGHT 0 // Okay
#define btnUP 1 // inc
#define btnDOWN 2 // dec
#define btnLEFT 3 // Select
#define btnSELECT 4 // Menu
#define btnNONE 5
#define beeper A1 // Alarm buzzer
#define shortBeep 100
#define longBeep 500
void setup()
{
Serial.begin(9600);
}
void loop()
{
lcd_call();
}
void lcd_call()
{
int button = read_LCD_buttons();
if(button==btnUP)
{
button_counter=button_counter+1;
Serial.print("button_counter");
Serial.println(button_counter);
}else if(button==btnDOWN)
{
button_counter=button_counter-1;
Serial.println(button_counter);
}
if (button_counter>5)
{
button_counter=1;
}else
while(button_counter<5)
{
int button = read_LCD_buttons();
if(button != prev_button && button != btnNONE)
{
prev_button = button;
//timedBeep(shortBeep,2);
}
if ((((button ==btnUP )||(button_counter==1))||((button ==btnDOWN )))&&(prev_button==btnUP))
{
digitalClockDisplay();//timedBeep(200,1);
}else if((((button ==btnUP )||(button_counter==2))||((button ==btnDOWN )))&&(prev_button==btnUP))
{
Display_angle();//timedBeep(200,1);
}else if((((button ==btnUP )||(button_counter==3))||((button ==btnDOWN )))&&(prev_button==btnUP))
{
Display_coordinate();//timedBeep(200,1);
}else if((((button ==btnUP )||(button_counter==4))||((button ==btnDOWN )))&&(prev_button==btnUP))
{
button_loop();//timedBeep(500,4);
}else if((((button ==btnUP )||(button_counter==5))||((button ==btnDOWN )))&&(prev_button==btnUP))
{
Display_Wind();//timedBeep(200,1);
}
}
}
void Display_Wind()
{
....Display Wind perameter........
}
void button_loop()
{
.....Button loop selection.........
}
void Display_coordinate()
{
.....Display coordinate.........
}
void Display_angle()
{
......Display angle........

void digitalClockDisplay()
