![]() ![]() The boards are equipped with sets of digital and analog input/output (I/O) pins that may be interfaced to various expansion boards ('shields') or breadboards (for prototyping) and other circuits. Īrduino board designs use a variety of microprocessors and controllers. Arduino boards are available commercially from the official website or through authorized distributors. Its hardware products are licensed under a CC BY-SA license, while the software is licensed under the GNU Lesser General Public License (LGPL) or the GNU General Public License (GPL), permitting the manufacture of Arduino boards and software distribution by anyone. Finally, it's time to turn on your RVR+/RVR and see what happens! If you used the provided software_serial_demo.ino file, you should see something like this: Getting NORDIC main application version.Arduino ( / ɑː r ˈ d w iː n oʊ/) is an open-source hardware and software company, project, and user community that designs and manufactures single-board microcontrollers and microcontroller kits for building digital devices. Move over to your terminal application and tell it to start reading from the serial port (in CoolTerm this is the Connect button). Next, use your A/B USB cable to connect the Arduino to the RVR+/RVR (don't turn the RVR+/RVR on just yet!). That's it! Now you can plug the USB side of the cable in to your computer. connect the TX pin to pin 2 (the RX pin) on the Arduino. ![]() connect the RX pin to pin 3 (the TX pin) on the Arduino.Then, hook them up to the Arduino as follows: You'll need to connect jumper wires to the RX and TX pins of the FTDI cable. Next we want to get the 5V FTDI Cable hooked up to your Arduino. The last thing to do is connect all your hardware! Once you've flashed your program to the Arduino, disconnect it from your computer. That should be all you need to do! If things don't seem to be working later, try playing around with the different options (like the USB port). Second, make sure the baudrate matches the one you used in your serial.begin() call. You can usually figure this out with trial and error (because it won't work if it's not reading from the right port!) There are two main things you'll need to do to get the terminal set up to print your output.įirst, you'll need to make sure the application is reading from the correct USB port. It's up to you which application you use, but we used CoolTerm. For this we use a serial port terminal application. Now that your code is all set up, you'll need a way to actually see the output that you're printing. Setting Up a Serial Port Terminal Application That's all there is to it! Now you can use your Software Serial connection to print output from your program, like this: serial.println( "Getting NORDIC main application version.") 115200 is the baud rate RVR+/RVR uses for serial communication. Inside the setup() function of your Arduino file, be sure to include this line to begin the serial connection. ![]() This will be important to note for when we're hooking everything up. In this declaration, we're using pin 2 as the RX pin and pin 3 as the TX pin. You'll need to declare an instance of SoftwareSerial to use in your code. The first thing you have to do to use any library is include it! SoftwareSerial serial ( 2, 3) This tutorial will walk you through the lines of code that set up and use this library. Using the SoftwareSerial LibraryĪ complete example of using the SoftwareSerial library can be found in software_serial_demo.ino. The SoftwareSerial library can configure other digital pins on your Arduino so that they can be used for serial communication. ![]() This is where Arduino's SoftwareSerial library comes in. If you want your Arduino program to print some output while also talking to RVR+/RVR, you may find that using the Arduino's built-in hardware for serial communication gives you messy results: Getting NORDIC main application version. This demo will walk you through how to set up a Software Serial connection using Arduino's SoftwareSerial library. ![]()
