The first step was making sure the Arduino would handle the TWI – there’s pretty much no reason it shouldn’t, because the Atmega8 certainly handles it. For some experiments, two-axes may be perfectly fine, and I’m happy to save the $11.) (I’m also looking at using a two-axis accelerometer that’s much less expensive than the three-axis one I’ve been using – $4 versus $15. The trade-off is a little bit more complicated protocols semantics, but nothing out of control. It only uses two-wires, rather than the four required for SPI, so schematic designs and board layouts become a bit more manageable. I’m doing this partially because it would be good to know how it works, but also because it’s electrically more compact. I have been using the Arduino and Atmel microcontroller’s generally using the SPI (serial-peripheral interface), but decided to look at the two-wire (a.k.a.

The library's source code will either be found there or else in the src subfolder.You are browsing the archives of the Near Future Laboratory blog. You can now navigate up a couple of folder levels to get to the library root folder. This will open the example sketch's folder under the examples subfolder of the library folder.

Select Sketch > Show Sketch Folder from the Arduino IDE's menus.Open any example sketch from the library you want to find.Select File > Examples from the Arduino IDE's menus.This isn't apparent to the user because the libraries have a standardized API. So the Wire library that is used when compiling for the Uno is completely different from the one used when compiling for the Nano 33 IoT, and so on. Each boards platform has its own version of the Wire library. Note that you might have multiple versions of a library installed on your computer and the active version may depend on which board you compile for. Select the board you are interested in from from the Arduino IDE's Tools > Board menu.

Hi I'll share a technique you can use to find the location of most any library.
