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, ...

There comes a time when you need to wire up three, four, or more identical i2c devices to a common microcontroller. Maybe you’re thinking about driving 128 seven-segment displays with eight of those ...

The past month or so I’ve been playing with the Maxim DS1307 Real-Time-Clock and DS1621 Temperature Sensor ICs. I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I ...

Modern interface isolators integrate interface transceivers with an internal isolation barrier. Older designs, prior to this integration, use separate, standalone isolators in combination with ...

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 Grove – I 2 C High Accuracy Temperature Sensor (MCP9808) is a pretty cute module based on MCP9808. In addition to high-precision temperature measurements, the module also offers a programmable ...
