func Stop

func Stop() error

Types

type GobotSimulator

type GobotSimulator struct {
	// contains filtered or unexported fields
}

func NewGobotSimulator

func NewGobotSimulator(adapter RaspiAdaptor) *GobotSimulator

NewGobotSimulator creates a bot that makes your machine behave like a raspberry pi in some ways

func (*GobotSimulator) AddKeyPressPWAction

func (sim *GobotSimulator) AddKeyPressPWAction(key rune, pin string, action int) (*gobot_sim.PinWriteAction, error)

AddKeyPressPWAction writes something to a pin when a key is pressed. It maps a key press to a specific action on a pin, for example to turn it on or simulate a button press and release

func (*GobotSimulator) Run

func (sim *GobotSimulator) Run() error

Run sets up the simulator bot and starts it

func (*GobotSimulator) SetPinToGPIOMap

func (sim *GobotSimulator) SetPinToGPIOMap(pinToGPIO *PinToGPIOMap)

SetPinToGPIOMap sets a pin mapping to gpio numbers for the platform (defaults to RPI3 mapping).

func (*GobotSimulator) WatchPin

func (sim *GobotSimulator) WatchPin(pin string, handler gobot_sim.PinChangedFunc) (*gobot_sim.PinWatcher, error)

WatchPin intercepts writes to a pin and calls a function if the value changed

type PinToGPIOMap

type PinToGPIOMap struct {
	// contains filtered or unexported fields
}

GPIOToPinMap maps gpio numbers to pins for a Raspberry revision

func NewPinToGPIOMap

func NewPinToGPIOMap(revision string, mapping map[string]string) *PinToGPIOMap

func (*PinToGPIOMap) Revision

func (m *PinToGPIOMap) Revision() string

func (*PinToGPIOMap) ToGPIO

func (m *PinToGPIOMap) ToGPIO(pin string) (string, error)

type RaspiAdaptor

	gpio.DigitalReader
	gpio.DigitalWriter
	gobot.Adaptor
}

type VAdaptor

type VAdaptor struct {
	PiBlasterPeriod uint32
	// contains filtered or unexported fields
}

VAdaptor is the Gobot VAdaptor for the Raspberry Pi

func NewVAdaptor

func NewVAdaptor(pinMap *PinToGPIOMap) *VAdaptor

NewVAdaptor creates a Raspi VAdaptor it is modified to accept a map of pins to gpio numbers, instead of the automatically determined map.

func (*VAdaptor) Connect

func (r *VAdaptor) Connect() (err error)

Connect starts connection with board and creates digitalPins and pwmPins adaptor maps

func (*VAdaptor) DigitalPin

func (r *VAdaptor) DigitalPin(pin string, dir string) (sysfsPin sysfs.DigitalPinner, err error)

func (*VAdaptor) DigitalWrite

func (r *VAdaptor) DigitalWrite(pin string, val byte) (err error)

DigitalWrite writes digital value to specified pin

func (*VAdaptor) Finalize

func (r *VAdaptor) Finalize() (err error)

Finalize closes connection to board and pins

func (*VAdaptor) GetConnection

func (r *VAdaptor) GetConnection(address int, bus int) (connection i2c.Connection, err error)

GetConnection returns an i2c connection to a device on a specified bus. Valid bus number is [0..1] which corresponds to /dev/i2c-0 through /dev/i2c-1.

func (*VAdaptor) GetDefaultBus

func (r *VAdaptor) GetDefaultBus() int

GetDefaultBus returns the default i2c bus for this platform
