===================================================== Easy MCP2221

Easy MCP2221 is a Python module to interface with Microchip MCP2221 and MCP2221A.

Connected to the USB port, this 14 pin chip part can provide a normal computer with the capabilities of a basic microcontroller.

MCP2221's peripherals:

• 4 GPIO
• 3 channel ADC
• DAC
• I2C
• UART
• Clock Output
• USB Wake-up via Interrupt Detection.

So you can practice the basics of digital electronics, microcontrollers, and robotics using nothing more than a regular computer, a breadboard, a few parts, and Python.

Quick start

Install:

.. code-block:: console

$ pip install EasyMCP2221

First run:

.. code-block:: python

>>> import EasyMCP2221
>>> mcp = EasyMCP2221.Device()
>>> print(mcp)
