For network applications, use the Client and Server classes as the basis.If it’s not appropriate, at least try to use its API as a model. Use the Stream and Print classes when dealing with byte streams.Use read ( ) to read inputs, and write ( ) to write to outputs, e.g.Use the established core libraries and styles. When writing examples and documentation, follow the Writing Style Guide You’ll likely come across a better term, and if not, you’ll have started the documentation on your library.ĭocument and comment as you go. When you have to use a domain-specific term, write a sentence or two describing it to the general public FIRST. To the general public, errors are bad things. For example, to programmers, an error is a notification that something happened. (“Wire” was probably a mistake, as the protocol it uses is typically called “TWI” or “I2C”.)Īvoid words that have different meanings to the general public. For example, “HTML” is relatively common and “SPI” is effectively the name of that protocol (“serial-peripheral interface” is probably too long).
Abbreviations are acceptable, though, if they’re in common use or are the primary name for something. For example, this is why we used analogWrite ( ) rather than pwm ( ). Pick terms that correspond to popular perception of the concept at hand. Use everyday terms instead of technical ones. Don’t be terse with your function names or variables. It abstracts away not only the low-level I2C commands, but also the mid-level temperature and pressure calculations, while still offering those mid-level functions as public functions for those who want them.

The library wraps this commonly executed series of functions into a high-level single command which returns the value the user's looking for in a format she expects. The readPressure ( ) function performs all the necessary steps to get the final pressure. Adafruit's BMP085 library is a good example. Think about what the average person thinks the thing does, and try to organise your API functions around that. Quite often, the command set for a particular electronic module is overly complicated for the most common uses, or can be re-organized around higher level functionality. Organize your public functions around the data and functionality that the user wants. For example, if there are only a few possible options for a particular setting, don’t use a function that takes an int, as it implies you can use any value you want. You don’t want to expose implementation details to the user but you also don’t want an API that suggests an inaccurate mental model of the possibilities. Match your API to the underlying capabilities. Come up with a clear mental model of the concept you’re working with, and the terms and functions you will use. Assume you are writing an API for an intelligent person who has not programmed before.

If you have suggestions on how to make Arduino libraries clearer for that core audience, please jump in the discussion.īe kind to the end user.
#ARDUINO 1 WIRE LIBRARY LICENSE CODE#
So please code with these principles in mind. We’re aware of that, but it’s what’s made it possible for so many beginners to get started with Arduino easily.

Some of these run counter to professional programming practice. It seems this library is not implemented with interrupts, so your program is blocked while waiting for master activity (which is perfectly acceptable in a lot of scenarios).This is a style guide to writing library APIs in an Arduino style. It didn't work for me (don't know if it's because of my hardware setup or for another reason), but it definitely work for others, so also worth a try. I also know at least one other library exists,, as commented above by Ryu_hayabusa. Sending bytes to the master is also asynchronous.
It's entirely implemented with interrupts, all communications are performed in background, you can execute other code as usual, in parallel, and are notified by callbacks when bytes are received etc. The library handles low level details: match rom, byte send and receive (which is actually quite hard to get right, mostly impossible without a logic analyzer). I use it in my custom home automation system, and it works flawlessly in my setup (the 1-wire master, a DS9490R, is connected to a laptop via USB, and also provides power to the Arduino, which is an Arduino Uno). I've just released a library to turn an Arduino board into a 1-wire slave, here: (edit: moved here ). As far as I know, the 1-wire library you linked in your question allows only to act as a master, not a slave.
