Member Function Documentation

Init() [1/2]

void daisy::GateIn::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.

Init() [2/2]

void daisy::GateIn::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.

State()

bool daisy::GateIn::State ( )

inline

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

Trig()

bool daisy::GateIn::Trig

(

)

Checks current state of gate input.

Returns

True if the GPIO just transitioned.
