disabling the touch and portexpander is not enough to use this library (only for display) and also use Wire library #define ESP_PANEL_DRIVERS_BUS_USE_ALL (0) #define ESP_PANEL_DRIVERS_BUS_USE_I2C (0) ...

This sketch will turn any Arduino into an I2C Slave whose pins can be manipulated by a master. Your wiring will look something like this (depending on your Arduinos): To keep the interface as simple ...

A while ago I received a couple of I/O port expander modules that use the I 2 C protocol. Using that Chinese module, you can use only the SDA and SCL pins of your Arduino, or any microcontroller ...

PJON, pronounced like the iridescent sky rats found in every city, is a cool one wire protocol designed by [gioblu]. [gioblu] wasn’t impressed with the complications of I2C. He thought one-wire was ...

[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 ...

eCosCentric Ltd. has contributed the generic I2C bus infrastructure from its eCosPro product line for inclusion within the public eCos project. According to Alex Schuilenburg, Managing Director at ...

YouTube channel How To Mechatronics has created a great tutorial with full instructions on how to create your very own Arduino powered 3D wire bending machine. Created using 3D printer parts, a ...
