Next steps shows how the master (Arduino) reads from the slave I2C device. Wire.requestFrom(address, 1) command expects to receive 1 byte of data from the TC74 sensor. Wire.available() waits for data ...

Some Arduino boards feature the I2C pins in different places, ... There is no setup needed to use the Arduino Wire library, as it comes installed in the Arduino IDE.

Arduino Setup For this experiment it is necessary to download and install the “Arduino I2C LCD” library. First of all, rename the existing “LiquidCrystal” library folder in your Arduino libraries ...

Arduino I2C Sniffer. 11 Comments . by: Caleb Kraft. May ... I think a good way to get around RAM limitations would be set up an interrupt on the pin you’re monitoring and a timer which counts ...

A lot of great ICs use I2C to communicate, but debugging a non-working I2C setup can be opaque, especially if you’re just getting started with the protocol/bus. An I2C bus scanner can be a he… ...

Update: Part3 is here (don’t get too excited..) This is all part of my personal challenge to quickly and accurately manually set 16bit numbers for microcontrollers.. Thanks to the earlier hard work of ...
