The headings on some .rst files were not following the expected heading order of using # for h1, * for h2, = for h3, and - for h4 This patch fixes that, and the doc/templates/*.tmpl files created for folks to use as templates for creating board and sample docs.

MCP9808 Temperature Sensor ########################## Overview ******** Sample application that periodically reads temperature from the MCP9808 sensor. Requirements ************ The MCP9808 digital temperature sensor converts temperatures between -20°C and +100°C to a digital word with ±0.5°C (max.) accuracy. It is I2C compatible and supports up to 16 devices on the bus. We do not require pullup resistors on the data or clock signals as they are already installed on the breakout board. The MCP9808 is available in a discrete component form but it is much easier to use it mounted on a breakout board. We used the Adafruit breakout board. - `MCP9808 Sensor`_ This sample uses the sensor APIs and the provided driver for the MCP9808 sensor. Wiring ******* The MCP9808 requires 2 wires for the I2C bus plus power and ground. The power can be either 5V or 3.3V. We connect the Data and clock wires to Analog ports A4 and A5 which is the I2C pins on Arduino compatible boards. In this hookup we are only connecting one device to one of the supported boards. It reads the temperature and displays it on the console. References *********** - http://www.microchip.com/wwwproducts/en/en556182 .. _`MCP9808 Sensor`: https://www.adafruit.com/product/1782
