## Detailed Description

Class for keys processing functionality

Definition at line 64 of file core.h.

## Constructor & Destructor Documentation

## ◆ NanoEngineInputs()

NanoEngineInputs::NanoEngineInputs | ( |  | ) |
| inline protected

Initializes Nano Engine Inputs object.

Definition at line 70 of file core.h.

## Member Function Documentation

## ◆ buttonsState()

static uint8_t NanoEngineInputs::buttonsState | ( |  | ) |
| inline static

Returns bits of all pressed buttons.

Returns bits of all pressed buttons. For example, to check if Down button is pressed you need to write `if (result & BUTTON_DOWN) {}`. Available constants are: BUTTON_DOWN, BUTTON_LEFT, BUTTON_RIGHT, BUTTON_UP, BUTTON_A, BUTTON_B.

Definition at line 96 of file core.h.

## ◆ connectCustomKeys()

static void NanoEngineInputs::connectCustomKeys | ( | TNanoEngineGetButtons | handler | ) |
| static

Configures NanoEngine8 to use custom key handler. You can implement in your handler any keyboard layout, you use in your schematics.

## ◆ connectGpioKeypad()

static void NanoEngineInputs::connectGpioKeypad | ( | const uint8_t * | gpioKeys | ) |
| static

Enables engine to use GPIO keys.

Enables engine to use gpio-keys. You need to pass globally defined array, containing GPIO pin numbers for the 6 buttons in the following order: Down, Left, Right, Up, A, B. If you don't want to use some specific button, then just set not used button to 0. Once you call this function, you can read buttons state via buttonsState().

Parameters

  gpioKeys | pointer to 6-button pins array.

  buttonsState()

## ◆ connectZKeypad()

static void NanoEngineInputs::connectZKeypad | ( | uint8_t | analogPin | ) |
| static

Enables engine to use Z-Keypad. Enables engine to use Z-Keypad. Please refer to arkanoid example for schematics.

Parameters

  analogPin | - pin, which Z-Keypad is connected to.

## ◆ notPressed()

static bool NanoEngineInputs::notPressed | ( | uint8_t | buttons | ) |
| static

Returns true if button or specific combination of buttons is not pressed. Returns true if button or specific combination of buttons is not pressed.

Parameters

  buttons | - buttons to check

Returns
  true of false

## ◆ pressed()

static bool NanoEngineInputs::pressed | ( | uint8_t | buttons | ) |
| static

Returns true if button or specific combination of buttons is not pressed. Returns true if button or specific combination of buttons is pressed.

Parameters

  buttons | - buttons to check

Returns
  true or false
