While the Raspberry Pi has very good support for an I2C bus, a lot of very cool chips – including the in system programmer for just about every ATtiny and ATmega microcontroller – use an SPI bus.

More often than not, an IoT master device uses the SPI (serial peripheral interface) and I 2 C (inter-integrated circuit) protocols to exchange data with EEPROMs or sensors that are operating in slave ...

TL;DR: The Raspberry Pi 3 Model B is out now. This latest model includes 802.11n WiFi, Bluetooth 4.0, and a quad-core 64-bit ARM Cortex A53 running at 1.2 GHz. It’s a usable desktop computer.

First, the new Pi 3 Model A+. This is a scaled-down and lower cost version of the Pi 3 Model B+. In the most important functional areas it is identical to the Pi3 B+: it has a 1.4GHz 64-bit quad-core ...

How does the latest Raspberry Pi board compare to its predecessors? The Raspberry Pi is the little computer that could. Selling for just $35, the UK-made machine has become something of a phenomenon, ...

I2C makes connecting multiple sensors to a Raspberry Pi straightforward by sharing just two pins for communication. With proper setup, scanning, and coding, you can integrate dozens of devices on a ...
