Types

type MCP3008

type MCP3008 struct {
	Mode, Bits byte
	Bus        embd.SPIBus
}

MCP3008 represents a mcp3008 8bit DAC.

func New

func New(mode, bits byte, bus embd.SPIBus) *MCP3008

New creates a representation of the mcp3008 convertor

func (*MCP3008) AnalogValueAt

func (m *MCP3008) AnalogValueAt(chanNum int) (int, error)

AnalogValueAt returns the analog value at the given channel of the convertor.
