-/** @mainpage
- * CN0357 single-supply, low noise, portable gas detector circuit using an
- * electrochemical sensor. The Alphasense CO-AX carbon monoxide sensor is used
- * in this example. Electrochemical sensors offer several advantages for
- * instruments that detect or measure the concentration of many toxic gases.
- * Most sensors are gas specific and have usable resolutions under one part per
- * million (ppm) of gas concentration.
- *
- * EVAL-CN0357 example program for MBED platforms. To achieve connection between
- * the shield and the ST Nucleo, the following connections need to be made:
- *
- * - ICSP pin 1 -> pin 12 of the Arduino header
- * - ICSP pin 3 -> pin 13 of the Arduino header
- * - ICSP pin 4 -> pin 11 of the Arduino header
- * - if VIN is not supplied, 5V to VIN
