In the Discord channel was mentioned that the I2C bus does not work for the STM32 board in Arduino mode. There is more than one problem: The local files for the I2C LCD display with "Wire2" do no ...

A tiny I2C-bus scanner with a nice tiny graphic OLED display and an AVR ATtiny44. This scanner displays the addresses of all attached I2C devices in a small matrix. The value is shiftet one bit to the ...

[Partner content] The Arduino® Plug and Make Kit™ introduces daisy-chaining extension modules on an I²C bus as a new way for rapid prototyping with Arduino. Targeted at beginners and makers alike, the ...

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 ...

Already back 2019 I have developed a working I2C slave implementation where master can read/write to address memory. BTW, this is still not working in Espressif IDE examples or Arduino Wire examples.

This articles describes how you can use I2C (TWI) communication, Arduino and temperature sensors to measure 3 different temperatures. It can be very helpful when you want to measure the outside, ...

[Johngineer] found himself in need of an I2C sniffer, but didn’t have one available. Necessity is the mother of invention, so he put together this I2C sniffer sketch for Arduino. The arduino will ...
