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.

PWM: Blink LED ############## Overview ******** This is a sample app which blinks a LED using PWM. The LED will start at a blinking frequency of 0.5Hz. Every 4 seconds, the blinking frequency will double. When the blinking frequency reaches 500Hz, the blinking frequency will be halved every 4 seconds until the blinking frequency reaches 0.5Hz. This completes a whole blinking cycle. From now on, the LED will repeat the blinking cycle for ever. Wiring ****** Arduino 101 and Quark D2000 CRB =============================== You will need to connect the LED to ground and PWM0 via the shield. You may need a current limiting resistor. See your LED datasheet. Nucleo_F401RE and Nucleo_L476RG =============================== Connect PWM2(PA0) to LED Nucleo_F103RB ============= Connect PWM1(PA8) to LED Building and Running ******************** This sample can be built for multiple boards, in this example we will build it for the arduino_101 board: .. code-block:: console $ cd samples/basic/blink_led $ make BOARD=arduino_101 $ make BOARD=arduino_101 flash After flashing the image to the board, the user LED on the board should start to blinking as discussed in overview
