Dependencies¶
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.
Installing from PyPI¶
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-mcp4728
To install system-wide (this may be required in some cases):
sudo pip3 install adafruit-circuitpython-mcp4728
To install in a virtual environment in your current project:
mkdir project-name && cd project-name
python3 -m venv .env
source .env/bin/activate
pip3 install adafruit-circuitpython-mcp4728
Usage Example¶
import board
import adafruit_mcp4728
i2c = board.I2C() # uses board.SCL and board.SDA
mcp4728 = adafruit_mcp4728.MCP4728(i2c)
mcp4728.channel_a.value = 65535 # Voltage = VDD
mcp4728.channel_b.value = int(65535/2) # VDD/2
mcp4728.channel_c.value = int(65535/4) # VDD/4
mcp4728.channel_d.value = 0 # 0V
mcp4728.save_settings() # save the current values to the eeprom,making them the default on power up
