This is a simple Arduino sketch for scanning slave address like FRAM (FM24CL16B), RTC module, I2C module for LCD, and more. I've tested on most ATmega328p MCU based boards (5V, 16 MHz) like Arduino ...
This very simple sketch scans the I 2 C-bus for devices. If a device is found, it is reported to the Arduino serial monitor. This sketch is the first step to get the I 2 C communication working. The ...
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 helpful ...
