This Arduino Mega sketch uses direct port read and bit manipulations to sniff an i2c bus running at up to 100 kHz. The analysis of the i2c communication is displayed on the Serial monitor. Connect SDA ...

DevKit on a bread board As well as wokwi simulation. An I2C deivce connected on each I2C bus (3.3v) Breakours have own pull up resistors (Checked with OLED scrren, and TOF sensor) The second I2C bus ...

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 ...

Last week, I covered some of the bitter details of an interesting hack that lets us split up the I²C clock line into multiple outputs with a demultiplexer, effectively giving us “Chip Selects” for ...

Arduino has just launched a “Plug and Make” kit designed for beginners with an Arduino UNO R4 WiFi board, several “Modulino” modules, a “Modulino” base to neatly attach the UNO R4 and modules, and ...

I2C is a two wire, clock synchronized protocol with a bi directional data line and a uni directional clock line. Its simplicity lies in its use of only two lines for communication and its complexity ...

The new ASX00073 UNO SPE shield from Arduino is now being shipped by authorized distributor Mouser Electronics. The ASX00073 shield brings advanced connectivity to new and existing projects with ...

The fundamentals of the Inter-Integrated Circuit (I2C) interface, and its associated protocol. What made this simple, robust, chip-to-chip interface so useful for embedded system applications? How the ...

I2C is a two-wire communication protocol known for its simplicity. Despite this reputation, I2C does have its challenges: a limited number of bits for a unique address can create address conflicts, or ...
