inline GateIn()

GateIn Constructor

inline ~GateIn()

GateIn Destructor

void Init(
    Pin pin,
    bool invert =true
)

Initializes the gate input with specified hardware pin.

Parameters:

pin_cfg pointer to pin to initialize
invert True if the pin state is HIGH when 0V is present at the input. False if input signal matches the pin state.

Note: the default for invert is true because it is typical to use an inverting input circuit (e.g. a BJT circuit) for eurorack gate inputs.

void Init(
    dsy_gpio_pin * pin_cfg,
    bool invert =true
)

Initializes the gate input with specified hardware pin.

Parameters:

pin_cfg pointer to pin to initialize
invert True if the pin state is HIGH when 0V is present at the input. False if input signal matches the pin state.

Note:

the default for invert is true because it is typical to use an inverting input circuit (e.g. a BJT circuit) for eurorack gate inputs.
deprectated - this function still works, but will eventually be removed. It uses the old style dsy_gpio_pin in a way that it is not compatible with the the new Pin class.

bool Trig()

Return: True if the GPIO just transitioned.

Checks current state of gate input.

inline bool State()

Checks current state of gate input (no state required) read function is inverted because of suggested BJT input circuit
