So graphics or even films can be reproduced in a visually appealing way.<br>Control is achieved using mini PCs such as Raspberry Pi, Arduino, BBC Microbit and many other modules. In our How-To, we implement the control with the most common developer board, the Raspberry Pi.<\/p>\n\n\n\n<p>The RB-MatrixCtrl controller board is ideal for control with the Raspberry Pi. With this expansion board, you can control up to three RGB LED matrix rows with a common HUB75 connector. In addition, a 25&#215;25 mm fan is installed, which provides the necessary cooling of the Raspberry Pi.<\/p>\n\n\n\n<p>A separate power supply unit (ideally with 5V and approx. 8A) is required to operate the LED matrix. A sufficient cable cross section must also be ensured.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Put the LED matrix into operation<\/strong><\/h2>\n\n\n\n<p>First, the cable for the power supply included in the set must be connected to the LED matrix and the power supply.<br>If several matrices are to be interconnected, proceed as follows: Up to three matrices can be operated in parallel on the 40-pin GPIO strip of the Raspberry Pi. In addition, further matrices can be connected in series to each matrix.<br>Use the HUB75 plug contact for this. This is marked on the matrix with <strong>IN<\/strong>. Additional matrices can be connected in series via the <strong>OUT <\/strong>contact.<\/p>\n\n\n\n<p><strong>Attention: <\/strong>When connecting several matrices, be sure to adjust the power supply accordingly!<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2020\/07\/LED-Matrix-in-Betrieb-nehmen-1.png\"><img

class=\"wp-block-heading\"><strong>Interposition of the matrix controller board<\/strong><\/h2>\n\n\n\n<p>As an alternative to connecting the matrices directly via the GPIO bar on the Raspberry Pi, you can also use the RB-MatrixCtrl controller board to control up to three matrices in parallel. Here, too, there is the option of connecting additional matrices in series.<\/p>\n\n\n\n<p>The advantage of control via the controller board is the significantly easier connection option. In addition, the controller board can supply the Raspberry Pi with power and has already installed a fan that provides sufficient cooling.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2020\/07\/Zwischenschaltung-des-Matrix-Controllerboards.png\"><img decoding=\"async\" src=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2020\/07\/Zwischenschaltung-des-Matrix-Controllerboards.png\" alt=\"\" class=\"wp-image-11172\" width=\"336\" height=\"286\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Assembly of the matrix controller board<\/strong><\/h2>\n\n\n\n<p>First plug the matrix controller board onto the GPIO bar of your Raspberry Pi. Now connect the HUB75 plugs of your matrices to the corresponding connections (Panel 1, Panel 2 &amp; Panel 3) on the controller board.<br>If you want to supply your Raspberry Pi with power directly via the controller board, you can also connect a voltage source of + 5V directly to the controller board. Please note that the connection is not protected against reverse polarity and reverse current. The connection is not suitable for supplying the matrix with power.<\/p>\n\n\n\n<p><strong>Important:<\/strong> Check the pin assignment of the E-pin (or LE) on the LED matrix. Depending on the matrix, this can vary between the fourth and eighth pin. Accordingly, you can adjust the assignment with the left jumpers on the controller board. Set the connection depending on the assignment of your matrix.<br>If the fourth or eighth pin of your matrix is \u200b\u200bon GND (or N), you should jump accordingly on the controller board.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full is-resized\"><a href=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2020\/07\/Montage-des-Matrix-Controllerboards.png\"><img decoding=\"async\" src=\"https:\/\/www.reichelt.de\/magazin\/wp-content\/uploads\/2020\/07\/Montage-des-Matrix-Controllerboards.png\" alt=\"\" class=\"wp-image-11174\" width=\"480\" height=\"272\"\/><\/a><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Installation of the LED matrix<\/strong><\/h2>\n\n\n\n<p>The first step in controlling the matrix with the Raspberry Pi is to install the associated library. Open the command terminal and enter the following:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apt-get update\nsudo apt-get install git\ngit clone https:\/\/github.com\/hzeller\/rpi-rgb-led-matrix<\/code><\/pre>\n\n\n\n<p>Then the onboard sound must be deactivated. Since the matrix uses a clock circuit that is also used by the onboard sound, simultaneous use is not possible.<br>If you still need a sound output, you should use an external USB sound adapter. To deactivate the onboard sound, first open the config file with the following command:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo nano \/boot\/config.txt<\/code><\/pre>\n\n\n\n<p>Find the line<strong> &#8220;dtparam = audio = on&#8221;<\/strong> and change it to <strong>&#8220;dtparam = audio = off&#8221;.<\/strong> Now save the file with the key combination <strong>Ctrl+O<\/strong>, confirm with Enter and then exit the editor with the key combination <strong>Ctrl+X<\/strong>.<\/p>\n\n\n\n<p>Then restart the Raspberry Pi for the change to take effect:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo reboot<\/code><\/pre>\n\n\n\n<p>With these commands you can reach the downloaded library and prepare the demo program:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>cd rpi-rgb-led-matrix\nmake -C examples-api-use<\/code><\/pre>\n\n\n\n<p>Now the demo program can be started. When starting the program, be sure to specify the number of LEDs per row and column. In our case there are 64 LEDs per row and column.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo examples-api-use\/demo -D 0 --led-rows=64 --led-cols=64<\/code><\/pre>\n\n\n\n<p>Then you can adjust the speed, for example if you have a slower panel or a faster Raspberry Pi. The command <strong>&#8211;led-slowdown-gpio = &lt;0 &#8230; 4&gt; <\/strong>can only be executed with values between 0 and 4.<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo examples-api-use\/demo -D 0 --led-rows=64 --led-cols64 --led-slowdown-gpio=2<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\"><strong>Use with Python<\/strong><\/h2>\n\n\n\n<p>To control the matrix with Python, you can execute the following commands in the terminal:<\/p>\n\n\n\n<p><strong>FOR PYTHON 2:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apt-get update\nsudo apt-get install python2.7-dev python-pillow -y\nmake-build-python\nsudo make install-python<\/code><\/pre>\n\n\n\n<p><strong>FOR PYTHON 3:<\/strong><\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>sudo apt-get update\nsudo apt-get install python3-dev python3-pillow -y\nmake-build-python PYTHON=$(which python3)\nsudo make install-python PYTHON=$(which python3)<\/code><\/pre>\n\n\n\n<p>How to get to the Samples folder:<\/p>\n\n\n\n<pre class=\"wp-block-code\"><code>cd bindings\/python\/samples<\/code><\/pre>\n\n\n\n<p>There you will find various examples for testing your matrix.
