The device has a fixed I2C address of 0x51 (81) so only one RTC per I2C bus can be used. The I2C communication supports 0.9-5.0 V so any 3.3V MCU should be able to connect. Do not forget appropriate ...

There are examples in many of the classes that demonstrate basic usage patterns. The I2Cdev class is built to be used statically, reducing the memory requirement if you have multiple I2C devices in ...

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 ...

[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 … ...

I had one of those why-didn’t-I-think-of-it moments this week, reading this article about multiplexing I2C on the ESP32 microcontroller. The idea is so good, and so simple, that it’s almost ...

They feature connectivity peripherals, including Ethernet, CAN, and USB (Full-Speed Host, Device and OTG), plus peripherals such as multiple timers, a 16-channel 1Msample/s analogue-to-digital ...

PYGO boards are also stackable on top of each other on the same Arduino board and have built-in measurement redundancies. The level shifters for voltage are integrated to allow I2C sensors to work ...
