![]() This make the communication not byte to byte controlled as I want it to be for my need. I realized that if I wanted to make an Arduino slave, when receiving from master, it actually reads from a buffer that is already previously received. 7 contributors 378 lines (323 sloc) 10.4 KB Raw Blame / TwoWire.cpp - TWI/I2C library for Wiring & Arduino Copyright (c) 2006 Nicholas Zambetti. But let’s start with the problem found in the Wire. When the limitations were somehow fixed, even though the small number of modifications (it is somehow a sort of hacking of the library) I found that the my final result were so useful to me that I thought was worth to write a short article about it. Place a jumper wire between REC and GND pins. Place a jumper wire between the REC and GND pins on the board, then press the reset button. Connect the board to your computer via USB. ![]() This can be solved through the following steps: 1. Then, when experimenting with a portability of a project in the Arduino environment, I started to trying the official Wire library, discovering some incompatibilities for my needs. Sometimes the board is not detected even when the board is connected to your computer. I have spent a lot of time on playing and later working on the I2C buses. I almost always used self developed libraries, both for learning and job requirement purposes. The proper place to put libraries is in a folder called 'libraries' in the sketchbook directory.
