EasyMCP2221 is a Python module to interface with Microchip MCP2221 and MCP2221A focused on ease of use.
The MCP2221 is a fully integrated USB-to-UART/I2C serial converter with four GP pins providing miscellaneous functionalities.
- MCP2221’s peripherals:
4 General Purpose Input/Output (GPIO) pins
3 channel 10 bit ADC
One 5 bit DAC
Clock Output with PWM
USB Wake-up via Interrupt Detection.
With this chip and this library you can practice the basics of digital electronics, microcontrollers, and robotics with a regular computer and regular Python. See Examples.
This is MCP2221 and MCP2221A pinout:
I am not related to Microchip Inc. in any way. This library is unofficial and for personal use only.
Some examples in this documentation show bare connections from your USB port to a breadboard. Most USB port controllers are protected against short-circuit between power and/or data lines, but some are not. I am not responsible for any damage you may cause to your computer. To be safe, always use an isolated powered USB hub for experimentation.
Many thanks to Microchip for providing free samples of MCP2221A, and for openly publishing the datasheet and documentation used to write this library.
