         '[dvlopt.linux.i2c.mcp342x :as adc])


(with-open [^java.lang.AutoCloseable bus (i2c/bus "/dev/i2c-1")]

  (i2c/select-slave bus
                    (adc/address true
                                 false
                                 true))

  (adc/configure bus
                 {::adc/channel    2
                  ::adc/mode       :continuous
                  ::adc/pga        :x1
                  ::adc/resolution :16-bit})

  (adc/read-channel bus
                    :16-bit)

  => {::adc/channel    2
      ::adc/micro-volt 913000
      ::adc/mode       :continuous
      ::adc/pga        :x1
