| <p><br></p> |
| <h3 id="objective">Objective</h3> |
| <p>Learn how to modify an existing app -- the <a href="../STM32F303/">blinky</a> app -- to light all the LEDs on the STM32F3 Discovery board. </p> |
| <p><br></p> |
| <h3 id="what-you-need">What you need</h3> |
| <ul> |
| <li>Discovery kit with STM32F303VC MCU</li> |
| <li>Laptop running Mac OSX. </li> |
| <li>It is assumed you have already installed and run the <a href="../STM32F303/">blinky</a> app succesfully.</li> |
| </ul> |
| <p><br></p> |
| <p>Since you've already successfully created your blinky app project, you'll need to modify only one file, main.c, in order to get this app working.</p> |
| <p><br></p> |
| <p>The main.c file resides in the apps/blinky/src directory in your project folder so you can edit it with your favorite editor. You'll make the following changes:</p> |
| <p><br></p> |
| <p>Replace the line:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #A90D91">int</span> <span style="color: #000000">g_led_pin</span>; |
| </code></pre></div> |
| |
| <p>With the line:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #A90D91">int</span> <span style="color: #000000">g_led_pins</span>[<span style="color: #1C01CE">8</span>] <span style="color: #000000">=</span> {<span style="color: #000000">LED_BLINK_PIN_1</span>, <span style="color: #000000">LED_BLINK_PIN_2</span>, <span style="color: #000000">LED_BLINK_PIN_3</span>, <span style="color: #000000">LED_BLINK_PIN_4</span>, <span style="color: #000000">LED_BLINK_PIN_5</span>, <span style="color: #000000">LED_BLINK_PIN_6</span>, <span style="color: #000000">LED_BLINK_PIN_7</span>, <span style="color: #000000">LED_BLINK_PIN_8</span>}; |
| </code></pre></div> |
| |
| <p>So that you now have an array of all 8 LED Pins on the board.</p> |
| <p>Delete the line:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #000000">g_led_pin</span> <span style="color: #000000">=</span> <span style="color: #000000">LED_BLINK_PIN</span>; |
| </code></pre></div> |
| |
| <p>And in its place, add the following lines to initialize all the LED_PINS correctly:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #A90D91">int</span> <span style="color: #000000">x</span>; |
| <span style="color: #A90D91">for</span>(<span style="color: #000000">x</span> <span style="color: #000000">=</span> <span style="color: #1C01CE">0</span>; <span style="color: #000000">x</span> <span style="color: #000000"><</span> <span style="color: #1C01CE">8</span>; <span style="color: #000000">x++</span>){ |
| <span style="color: #000000">hal_gpio_init_out</span>(<span style="color: #000000">g_led_pins</span>[<span style="color: #000000">x</span>], <span style="color: #1C01CE">1</span>); |
| } |
| <span style="color: #A90D91">int</span> <span style="color: #000000">p</span> <span style="color: #000000">=</span> <span style="color: #1C01CE">0</span>; |
| </code></pre></div> |
| |
| <p>We'll use that 'p' later. Next you'll want to change the line:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #000000">os_time_delay</span>(<span style="color: #1C01CE">1000</span>); |
| </code></pre></div> |
| |
| <p>to a shorter time in order to make it a little more interesting. A full 1 second delay doesn't look great, so try 100 for starters and then you can adjust it to your liking.</p> |
| <p>Finally, change the line:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #000000">hal_gpio_toggle</span>(<span style="color: #000000">g_led_pin</span>); |
| </code></pre></div> |
| |
| <p>to look like this:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code><span style="color: #000000">hal_gpio_toggle</span>(<span style="color: #000000">g_led_pins</span>[<span style="color: #000000">p++</span>]); |
| <span style="color: #000000">p</span> <span style="color: #000000">=</span> (<span style="color: #000000">p</span> <span style="color: #000000">></span> <span style="color: #1C01CE">7</span>) <span style="color: #000000">?</span> <span style="color: #1C01CE">0</span> <span style="color: #000000">:</span> <span style="color: #000000">p</span>; |
| </code></pre></div> |
| |
| <p><br></p> |
| <h3 id="build-the-target-and-executables-and-download-the-images">Build the target and executables and download the images</h3> |
| <p>Run the same commands you used on the blinky app to build and load this one:</p> |
| <div class="codehilite" style="background: #ffffff"><pre style="line-height: 125%;"><span></span><code>$ newt create-image stmf3_blinky 1.2.3 |
| App image successfully generated: ~/dev/myproj/bin/stmf3_blinky/apps/blinky/blinky.img |
| Build manifest:~/dev/myproj/bin/stmf3_blinky/apps/blinky/manifest.json |
| $ newt -v load stmf3_boot |
| $ newt -v load stmf3_blinky |
| </code></pre></div> |
| |
| <p><br></p> |
| <h3 id="watch-the-leds-go-round-and-round">Watch the LEDs go round and round</h3> |
| <p>The colored LEDs should now all light up in succession, and once they're all lit, they should then go off in the same order. This should repeat continuously.</p> |
| <p>If you see anything missing or want to send us feedback, please do so by signing up for appropriate mailing lists on our <a href="../../../community/">Community Page</a>.</p> |
| <p>Keep on hacking and blinking!</p> |
