![]() The path UKHeliBob provided is the version bundled with the copy of the Arduino AVR Boards platform that comes with the Arduino IDE. The reason you won't find the platform bundled libraries listed in Arduino Library manager is because these libraries are distributed along with the boards platforms and it wouldn't really make sense to distribute the libraries by themselves (because you will often need to have multiple versions installed at the same time).Įach boards platform bundles its own version of the Wire library. In the case of libraries providing essential capabilities, such as Wire, it makes the most sense to provide the library along with the boards platform that adds Arduino support for that architecture. Some libraries are very architecture-specific, so that the code is very much written for a certain family of microcontrollers. Create a quick-start node that reads an NFC tag to serve most common purposes.Wire is what's known as a "platform bundled library".For the new type, create action nodes that correspond to the functions and methods provided by the third-party C++ library.Declare a dependency on a third-party C++ library so that XOD knows where to download it, saving users from manual install.There may be several instances of this node, one for each hardware module. Declare a new custom type pn532-device, which describes an RFIC/NFC module and how is it connected to an Arduino board.In order not to go into the details of working with tags, we will take the Adafruit-PN532 Arduino library and just wrap it in XOD nodes. Imagine that we want our Arduino board to turn the built-in led on or off when we bring an NFC tag, such as travel pass, to it.Ĭonsider that we have no XOD library to work with RFID/NFC scanner PN532 ( xod-dev/pn532-nfc), and try to make it on our own. Also, you need to have some experience of working with C++ libraries for Arduino. To understand this guide, you have to know how to write C++ code in XOD and how to work with custom types. ![]() Many libraries already have been written for Arduino and they can be included into XOD to use the full power of the existing ecosystem. ![]()
