## Examples

Read GP0

```python

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()

mcp2221.InitGP(0, MCP2221.TYPE.INPUT)

print(mcp2221.ReadGP(0))

```

Write GP0

```python

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()

mcp2221.InitGP(0, MCP2221.TYPE.OUTPUT)

print(mcp2221.WriteGP(0, 1))

```

Read ADC on GP1

```python

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()

mcp2221.InitGP(1, MCP2221.TYPE.ADC)

mcp2221.SetADCVoltageReference(MCP2221.VRM.VDD)

print(mcp2221.ReadADC(1))

```

Write DAC on GP2

```python

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()

mcp2221.InitGP(2, MCP2221.TYPE.DAC)

mcp2221.SetDACVoltageReference(MCP2221.VRM.REF_2_048V)

mcp2221.WriteDAC(12)

```

## Tests
