MCP2221 CLI

A command-line interface for the MCP2221 USB to I2C and GPIO converter.

This allows you to interact in a simple manner with a connected MCP2221 without having to write a standalone program to, for example, send and receive I2C data or change settings.

The CLI uses mcp2221-hal, which you might like to check out if you're writing embedded-hal device drivers via an MCP2221.

Features

• I2C: read, write, write-read, address check
• GPIO: read digital input, set digital output
• Analog input (ADC) and output (DAC)
• Configure pins into other modes (activity indication, for example)
• Change USB device information, such as product and manufacturer strings.
• Reset the device

Installation

For the moment, just use Cargo:

cargo install --locked mcp2221-cli
