MultiDesktop little library for easy buttons + screen coding.
I use https://github.com/neu-rah/ArduinoMenu for button support and for Menu printing.
The first example with control through Serial:
//We have 2 'buttons' for actions. They are characters readed from Serial, or push buttons of ArduinoMenu library.
int8_t codes[] = { '+' , '-' };
// The 3rd button - button to change desktop
MultiDesktop<2> multi_desktop( '*' , codes);
// Create desktop
void show_1_screen() { /* show smth */ }
void up() { /*do smth by press '+' */ }
void down() { /*do smth by press '-' */ }
// Callback list size == 2 !
func desktop1cb[] = { &up, &down };
Desktop<2> mainDesktop(&show_1_screen, desktop1cb);
// Create another desktop
void show_2_screen() { /* show smth 2 */ }
void led_button() { /* turn led */ }
// If you don't want to use some buttons, write 0 !
func desktop2cb[] = { &led_button, 0 };
Desktop<2> secondDesktop(&show_2_screen, desktop2cb);
Add desktop to MultiDesktop in setup function:
multi_desktop.add_desktop(&mainDesktop);
multi_desktop.add_desktop(&secondDesktop);
multi_desktop.show();
Enjoy:
void loop()
{
if (Serial.available())
{
char ch = Serial.read();
multi_desktop.button_pressed(ch);
multi_desktop.show();
}
delay(1);
}
See examples in source folder:
- serial_2leds_2codes.cpp
- Input '+' '*' from Serial, 2 desktops, 1 actions on each desktop : toggle own LED
- serial_3codes.cpp
- Input '+' '-' '*' from Serial, 3 desktops, 1-2 actions: print smth
- serial_button_3codes.cpp
- Input '+' '-' '*' from Serial or 3 buttons, 3 desktops, 1-2 actions: print smth
- serial_button_led_menu_3codes.cpp
-
Input '+' '-' '*' from Serial or 3 buttons:
-
Desktop 1: message
-
Desktop 2: toggle LED
-
Desktop 3: start menu
-
Menu: toggle LED
