# 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).
**Cargo.toml**
```toml
dac_lib_mcp4725 = {git = 'https://github.com/jake-g00dwin/dac_lib_mcp4725'}
```
### Running Tests
To run the tests for the project after downloading or cloning the repo
```sh
cargo test
```
## Roadmap
- [X] Define all Bitmasks for registers.
- [X] Add Example usage documentation.
- [ ] Add link to example usage repo
- [ ] Ensure Async compat
- [ ] Add parameters for selecting power down modes.
