Hi,
I want make a LCD Menu with Joystick. I this found a Menu library: Phi_prompt | LiuDr Electronic Solutions LLC Official Blog
I managed to make the menu with analog buttons, but I want to work with the joystick. The joystick has 2 analog outputs ("x" and "y" axis )and 1 digital output (press).
With this library seems easier to use the joystick but not implement it in the menu: phi_interfaces | LiuDr Electronic Solutions LLC Official Blog
menu library with analog buttons:
#define buttons_per_column 5 // Each analog pin has five buttons with resistors.
#define buttons_per_row 1 // There are two analog pins in use.
#define name_length 8 // This is the max length of names.
char analog_mapping[]={'R','U','D','L','B'}; // This is an analog keypad.
byte analog_pins[]={0}; // The pin numbers are analog pin numbers.
int values[]={0, 143, 328, 503, 741}; //These numbers need to increase monotonically. The 342 works better on my setup but you will need to change it back.
phi_analog_keypads analog_keypad(analog_mapping, analog_pins, values, analog_buttons_per_row, analog_buttons_per_column);
// This serial keypad is for debugging.
phi_serial_keypads debug_keypad(&Serial,9600);
// The following sets up function keys for phi_prompt library
char up_keys[]={"U"}; ///< All keys that act as the up key are listed here.
char down_keys[]={"D"}; ///< All keys that act as the down key are listed here.
char left_keys[]={"L"}; ///< All keys that act as the left key are listed here.
char right_keys[]={"R"}; ///< All keys that act as the right key are listed here.
char enter_keys[]={"B"}; ///< All keys that act as the enter key are listed here.
char escape_keys[]={"A"}; ///< All keys that act as the escape key are listed here.
char * function_keys[]={up_keys,down_keys,left_keys,right_keys,enter_keys,escape_keys}; ///< All function key names are gathered here fhr phi_prompt.
// The following adds all available keypads as inputs for phi_prompt library
multiple_button_input * keypads[]={&analog_keypad, &debug_keypad,0};

/** \brief class for 2-axis joy sticks
* \details This class provides support to sense a 2-axis joy stick, with either analog output on each axis, or digital output of 8 directional keys.
* These function codes, coupled with the lower level function code of each inheriting child class, completes the translation from sensing physical pins to outputting named buttons with mapping array.
* The function hierarchy is getKey()<---scanKeypad()<---sense_all().
* The sense_all reads digital pins for input.
* The scanKeypad turns these inputs into status changes for keys and provide scan code of the pressed key. It handles status change including debouncing and repeat.
* The getKey translates the key press from scan code (0 to max_key-1) into named keys with the mapping array.

please someone could help me?
thank you!
