dac_lib_mcp4725

A rust library for the MCP4725 DAC module

Current State

The library has been tested manually using a breakout board and 3.3v input for the supply. Output for 4095 yields near full voltage on the output pin.

Description

The MCP4725 is a 12bit Digital to Analog converter with built in EEPROM memory.

I2C Speeds:

• Standard 100 kbps
• Fast 400 kbps
• High-Speed 3.4 Mbps

Connections:

OUT:: Signal Output Analog voltage GND:: Signal Output Ground SCL:: I2C Clock SDA:: I2C Data VCC:: Supply voltage 2.7v to 5.5v GND:: Ground

Usage

Adding to project

There are two ways to add the crate/repo to your project. You can use the github URL or you can add it via the normal crates name(TBD).
