Clojure library for talking to the MCP342x family of A/D converters using

[I2C](https://en.wikipedia.org/wiki/I%C2%B2C) :

- MCP3421

- MCP3422

- MCP3423

- MCP3424

- MCP3425

Relies on [helins/linux.i2c](https://github.com/helins/linux.i2c.clj).

## Usage

This is an overview.

The [detailed API is available on Cljdoc](https://cljdoc.org/d/io.helins/linux.i2c.mcp342x).

In short, without error handling :

```clj

(require '[helins.linux.i2c         :as i2c]

         '[helins.linux.i2c.mcp342x :as mcp342x])

(with-open [bus (i2c/bus "/dev/i2c-1")]

  (i2c/select-slave bus

                    (mcp342x/address true

                                     false

                                     true))

  (mcp342x/configure bus

                     {:mcp342x/channel    2

                      :mcp342x/mode       :continuous

                      :mcp342x/pga        :x1

                      :mcp342x/resolution :16-bit})

  (mcp342x/read-channel bus

                        :16-bit)

  => {:mcp342x/channel    2

      :mcp342x/micro-volt 913000

      :mcp342x/mode       :continuous

      :mcp342x/pga        :x1

      :mcp342x/resolution :16-bit})

```
