There are some really powerful libraries with lots of support. In this post I&rsquo;ll post the simplest possible &ldquo;Hello World&rdquo; example on an SSD1306 using an Arduino Due. Note, if you need to draw shapes, lines, movement you&rsquo;ll have to extend this example.</p> <p><img src="https://lloydroc.github.io/assets/jpg/ssd1306_arduino_hello_world.jpg" alt="Hello World SSD1306 Arduino"></p>https://lloydroc.github.io/post/hardware/uart-rpi-and-arduino/Wed, 18 Mar 2020 14:02:54 +0000https://lloydroc.github.io/post/hardware/uart-rpi-and-arduino/<p>Using a 2-wire serial connection we can communicate from a Raspberry Pi (RPi) to an Arduino. For the Raspberry Pi we&rsquo;ll use the built in UART accessed through a <code>tty</code>, and the Arduino we&rsquo;ll use the <a href="https://www.arduino.cc/reference/en/language/functions/communication/serial/">Serial</a> Communication Library.</p> <h1 id="what-this-example-does">What this Example Does?</h1> <p>This example will use a RPi and Arduino to send a fixed message from the RPi to the Arduino. The Arduino will then echo what it receives back the RPi. The hardware used was a RPi B+ and the Arduino Due. The code is all in C/C++.</p>
