Python driver for MCP2221/A

Examples

Read GP0

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()
mcp2221.InitGP(0, MCP2221.TYPE.INPUT)
print(mcp2221.ReadGP(0))

Write GP0

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()
mcp2221.InitGP(0, MCP2221.TYPE.OUTPUT)
print(mcp2221.WriteGP(0, 1))

Read ADC on GP1

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

from MCP2221 import MCP2221

mcp2221 = MCP2221.MCP2221()
mcp2221.InitGP(2, MCP2221.TYPE.DAC)
mcp2221.SetDACVoltageReference(MCP2221.VRM.REF_2_048V)
mcp2221.WriteDAC(12)
