CircuitPython library for the MCP3xxx series of analog-to-digital converters.
Currently supports:
This driver depends on:
Please ensure all dependencies are available on the CircuitPython filesystem. This is easily achieved by downloading the Adafruit library and driver bundle.
On supported GNU/Linux systems like the Raspberry Pi, you can install the driver locally from PyPI. To install for current user:
pip3 install adafruit-circuitpython-mcp3xxxTo install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-mcp3xxxTo install in a virtual environment in your current project:
mkdir project-name && cd project-name python3 -m venv .venv source .venv/bin/activate pip3 install adafruit-circuitpython-mcp3xxximport busio import digitalio import board import adafruit_mcp3xxx.mcp3008 as MCP from adafruit_mcp3xxx.analog_in import AnalogIn # create the spi bus spi = busio.SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) # create the cs (chip select) cs = digitalio.DigitalInOut(board.D5) # create the mcp object mcp = MCP.MCP3008(spi, cs) # create an analog input channel on pin 0 chan = AnalogIn(mcp, MCP.P0) print('Raw ADC Value: ', chan.value) print('ADC Voltage: ' + str(chan.voltage) + 'V')import busio import digitalio import board import adafruit_mcp3xxx.mcp3008 as MCP from adafruit_mcp3xxx.analog_in import AnalogIn # create the spi bus spi = busio.SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) # create the cs (chip select) cs = digitalio.DigitalInOut(board.D5) # create the mcp object mcp = MCP.MCP3008(spi, cs) # create a differential ADC channel between Pin 0 and Pin 1 chan = AnalogIn(mcp, MCP.P0, MCP.P1) print('Differential ADC Value: ', chan.value) print('Differential ADC Voltage: ' + str(chan.voltage) + 'V')import busio import digitalio import board import adafruit_mcp3xxx.mcp3004 as MCP from adafruit_mcp3xxx.analog_in import AnalogIn # create the spi bus spi = busio.SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) # create the cs (chip select) cs = digitalio.DigitalInOut(board.D5) # create the mcp object mcp = MCP.MCP3004(spi, cs) # create an analog input channel on pin 0 chan = AnalogIn(mcp, MCP.P0) print('Raw ADC Value: ', chan.value) print('ADC Voltage: ' + str(chan.voltage) + 'V')import busio import digitalio import board import adafruit_mcp3xxx.mcp3004 as MCP from adafruit_mcp3xxx.analog_in import AnalogIn # create the spi bus spi = busio.SPI(clock=board.SCK, MISO=board.MISO, MOSI=board.MOSI) # create the cs (chip select) cs = digitalio.DigitalInOut(board.D5) # create the mcp object mcp = MCP.MCP3004(spi, cs) # create a differential ADC channel between Pin 0 and Pin 1 chan = AnalogIn(mcp, MCP.P0, MCP.P1) print('Differential ADC Value: ', chan.value) print('Differential ADC Voltage: ' + str(chan.voltage) + 'V')API documentation for this library can be found on Read the Docs.
