Types ¶

type MCP2210 ¶

type MCP2210 struct {
	// contains filtered or unexported fields
}

func Open ¶

func Open(vendorId uint16, productId uint16) (*MCP2210, error)

Opens a MCP2210 device with the given VendorId and ProductId.

func (*MCP2210) Close ¶

func (this *MCP2210) Close()

Closes the connection to the device.

func (*MCP2210) GetBytesPerTransfer ¶

func (this *MCP2210) GetBytesPerTransfer() int

func (*MCP2210) GetGPIOValue ¶

func (this *MCP2210) GetGPIOValue(pin uint16) (uint8, error)

Get the current value of a GPIO pin. Returns ValueInactive or ValueActive.

func (*MCP2210) GetInterruptCount ¶

func (this *MCP2210) GetInterruptCount() (uint16, error)

func (this *MCP2210) GetSPIClock() uint32

Returns the currently used SPI clock in Hz.

func (*MCP2210) ReadEEPROM ¶

func (this *MCP2210) ReadEEPROM(address byte) (byte, error)

Reads the byte stored at a specific address in EEPROM.

func (*MCP2210) SetGPIOValue ¶

func (this *MCP2210) SetGPIOValue(pin uint16, state uint16) error

Sets the value of a GPIO pin. pin Number of the pin to set. state New pinstate, use ValueInactive or ValueActive

func (*MCP2210) WriteEEPROM ¶

func (this *MCP2210) WriteEEPROM(address byte, data byte) error

Writes data to the specified Address in EEPROM.

func (*MCP2210) Xfer ¶

func (this *MCP2210) Xfer(sendBuffer []byte) ([]byte, error)

Sends some bytes and returns the received bytes
