[Thomas] wanted to play around with a few high-power LEDs and a RaspberryPi. LED controllers usually require some form of PWM to change the brightness of a LED, and unfortunately the Pi only has one ...

At first glance, using a microcontroller for a simple fancy light project is overkill. However, the existing design can be modified later without additional hardware. Often a few extra code lines will ...

This project implements a dynamic PWM (Pulse Width Modulation) device driver for the Raspberry Pi, together with a user-space application that allows real-time control of PWM channels through IOCTL ...

This will download and run the installation script, which will check for an existing installation, install/update dependencies, build the application, and help you configure your LED panel. First ...

I am supposed to be on other duties this week, but cannot resist pointing you in the direction of the new Raspberry Pi in-house MCU, the RP2040. Much as I want to write chapter and verse about the ...

The Pi Zero is a great piece of hardware, even if you’re not designing another USB hub for it. [Marcel] wanted to control a few RGB LED strips from his phone, and while there are a lot of fancy ways ...

The Raspberry Pi 5 brought a more powerful CPU and GPU and faster I/Os compared to the Raspberry Pi 4, as well as some incompatibilities. While the transition from a Raspberry Pi 4 to a Raspberry Pi 5 ...
