Check out LIN and I2C for low speed networking needs. They are often better alternatives than SPI or CAN for many applications. The serial peripheral interface (SPI) and universal asynchronous ...

To the average microcontroller, Ethernet networks are quite a step up from the basic I2C, SPI and UART interfaces, requiring either a built-in Ethernet MAC or SPI-based MAC, with tedious translation ...

The UART, or universal asynchronous receiver-transmitter, is one of the most used device-to-device communication protocols. This article shows how to use a UART as a hardware communication protocol by ...

In embedded systems, SPI (Serial Peripheral Interface) and I2C (Inter-Integrated Circuit) protocols are both used for communication between microcontrollers and other integrated circuits. Which of ...

The I2C (Inter-Integrated Circuit) Bus invented in 1980 by Philips Semiconductors (NXP Semiconductors today) was a massive step forward in simplifying communications in embedded systems. It is a ...

An Inter-IC bus is often used to communicate across circuit-board distances. Here’s a primer on the protocol. At the low end of the spectrum of communication options for “inside the box” communication ...

We’ve gotten used to the GPIO-available functions of Raspberry Pi computers remaining largely the same over the years, which is why it might have flown a little bit under the radar: the Raspberry Pi 4 ...
