Then to initialize the library, start off all the I2C operations, you gotta call wire.begin, and you would do this in your setup. Include, in this case it's Wire.h, so that's the header file. So first, to start off using library, like with all libraries you get start off with a hashtag, include with appropriate hashtag. But the Wire Library is what accesses I2C. Maybe it's the license lease name or stuff, I don't really don't. Why they don't call it I2C, I'm not sure. So the Wire Library is used to access I2C. They are doing a library that supports I2C, so that's called Wire. So you cant be using the MicroCore ATTiny13 Core and expect it.īasic computer skills: On Windows use dir s to search for files.So, now we're talking about the library. This will only impact you if you are programming obscure and small Micros with the IDE. You need to have the target board selected before you compile, not all boards have a Wire.h library. That means I have to use include but physically I do not need it in library folder Or I have to remove this from the sketch.
Therefore you have the latest version of the Wire library installed.
If you are using only a slightly old IDE version then you might encounter problems from updating your version of Arduino AVR Boards and if you do need to get the latest version of Arduino AVR Boards you might need to also update to the latest version of the Arduino IDE (1.8.5).Īrduino AVR Boards says Installed and no update button - it looks like is also OK.īut in the sketch I have: include include So it looks I need this - or Im doing something wrong Thx. If you are using a very old IDE version then you will not have Boards Manager. Note that the above instructions require you to be using a recent version of the Arduino IDE. If you dont see an Update button then you already have the latest version installed.
