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 ...

Assume that you are moving towards a complex microcontroller project bundled with blinkers, beepers, and a display panel. To link a standard 16×2 LCD directly with the microcontroller, for instance ...

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 ...

Electronic hobbyist Jin Zhu based in San Francisco has started a Kickstarter campaign to create a new elegant TWI/I2C library for AVR Mega series MCU, which is available from just $5 and is expected ...
