Below are a number of Arduino resources that may be useful if you want to start writing or modifying code for your RFzero. If you only want to load and use the programs, e.g. for operating a beacon, you don’t need to know anything about Arduino or writing code.

Arduino references

The Arduino homepage

The Arduino language reference

The Arduino forum and the Arduino Zero forum, keep in mind that the RFzero is by and large an Arduino Zero with GPS and RF. Thus, if you are looking for something that is very Arduino related it might be an idea to see if someone else has solved it for the Arduino Zero.

Arduino IDE language

If you want to change the language used in the Arduino IDE you can do this in the Menu | File | Preferences – if you run it in English. However, since you probably don’t do, since you want to change into English, you can use the positions in the menu instead, which is then first from the left (File in English) and then scroll down to the second option from the bottom (Preferences in English).

Location of the Arduino IDE preferences.

Then change the Editor language to English (English).

There are a number of benefits from changing the Arduino IDE language to English:

  1. The lingua franca of programming is English
  2. When you search for help there are more web pages available
  3. The majority of posts on the Arduino forum are in English
  4. It will be easier for you to follow the instructions on the RFzero homepage and many other webpages too

Recommended changes to the Arduino IDE preferences.

You may also want to enable display line numbers and to automatically save the files when you verify or upload the code.
