Now that Raspberry Pi 4 stocks have returned to normal, we thought it was time to write an article about the power of this microcomputer. So if you’ve already got one and you want to learn more or if you’re thinking about getting one and want to get more details – this is the article…
Read MoreEverything about Sound Output Using the Pico W
The Raspberry Pi Pico W is a powerful microcontroller board built around the Raspberry Pi’s very own microcontroller chip, the RP2040. You can check out a selection of RP2040-based microcontroller boards here or keep reading to find out everything you need to know about sound output using the Pico W. Have you ever considered making…
Read MoreUART – The Universal Asynchronous Receiver-Transmitter
UART is a full duplex serial interface. It enables two devices to communicate over just three wires and supports variable speeds. UART Characteristics Like the name suggests, UART is an asynchronous interface. Unlike SPI or I2C there is no need for a dedicated clock. The two devices just need to use the same transmission speed.…
Read MoreI2C – The Inter-Integrated Circuit Bus
The I2C bus is very commonly used in the embedded realm. We explain how it works and how to set it up on the Raspberry Pi with an example. I2C Characteristics The Inter-Integrated Circuit Bus is a synchronous serial communication bus. Philips Semiconductors was responsible for the invention in 1982 but the interface quickly gained…
Read MoreA GPIO Guide for Beginners
In this blog post you will learn everything about the GPIO pins of the Raspberry Pi. This post is especially for newbies in electronics. First of all, a warning: The Raspberry Pi can be irreparably damaged if the pins are used incorrectly. So always make sure your circuit is correct and that you use enough…
Read MoreCircuitPython, Adafruit Feather RP2040, and I2C
As you probably guessed by the title, this article discusses CircuitPython, the Adafruit Feather RP2040, and the I2C communication protocol. The RP2040 has two I2C controllers – good for example, when you want to run two I2C devices with the same I2C address. In my test setup, I have an Adafruit Feather RP2040 microcontroller board,…
