Open your Arduino IDE and click on Sketch -> Import Library -> Add Library….Here are the steps necessary to install the I2C Library… In addition to this, the commands are a little more clean to use as you’ll soon discover.ĭownloading and installing the I2C Library The I2C library resolves this problem, by adding an extensive timeout feature, such that if something doesn’t equal value within a specific length of time, an error code will be generated, and control will be returned. There are quite a few entries in wire.cpp that essentially read like this…īasically, the possibility exists for the code to enter this while loop and never exit if something never equals value. I scoured the schematic, went back and forth with the chip manufacturer, and finally concluded that the problem was with the Arduino itself, not with the chip. While doing some testing on the I2C Display, I discovered that the poor thing would freeze randomly after a few seconds of operation. The I2C Library can be downloaded here: I2C Library Rev 5 No hardware is necessary for this module. No schematic is necessary for this module.
