SunFounder Fusion HAT+ for Raspberry Pi 5/4/3B+ and Zero single board computers is a motor control and GPIO expansion board ...

The PCA9698 is an I2C, 40 pins parallel IO expander. These 40 pins can be configured as INPUT or OUTPUT and are addressable via 5 banks (groups) of 8 IO pins. The library provides read/write access to ...

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 ...

The I2C and I3C interconnect technologies are close cousins, both conceived as interfaces for short-haul (intra-board) communication between integrated circuits and other digital devices. As we shall ...

I2C is a two-wire, bidirectional bus protocol that enables effective communication between one master (or multiple masters) and one or more slave devices. It is a straightforward, half-Duplex, ...

The inter-IC bus, or I2C bus for short, is a two-wire bus designed for connecting simple peripherals that do not require rapid transfer of large amounts of data. In this three-part series we will look ...

Developers, engineers and Arduino enthusiasts may be interested in a new open source piece of hardware designed for CAN bus Arduino projects. Combining several essential features into one complete ...

This project explains the interfacing of PCF8591 converter (slave) with ATmega328 microcontroller (master) using I2C bus to get direct multiple analogue inputs and outputs. ATmega328 microcontroller ...

Arduino has two new boards out which deliver connectivity – the Arduino MKR WAN 1300 (LoRa) and the Arduino MKR GSM 1400. The Arduino MKR WAN 1300 delivers LoRa low-power WAN connectivity, and the ...
