Flashing your code into an Arduino, an ESP32 or any other modern microcontroller platform is pretty straightforward: connect the device through USB, fire up the appropriate software platform, and press “program”. But those who followed embedded programming classes in the ’80s and ’90s will remember a more complicated procedure that consists of swapping EPROM chips …

As a standard feature of the Linux kernel, device tree overlays (DTOs) allow for easy enabling and configuration of features and drivers, such as those contained within the standard firmware of a Raspberry Pi system. Using these DTOs it’s trivial to set up features like as a soft power-off button, triggering an external power supply and enable …

Whether you can’t afford a USB controller, or you just want the the challenge, making your own retro game controller is a great idea! This controller will use the GPIO pins on the Raspberry Pi, so you will need some experience working with electronics. Otherwise, you might fry your Pi. Also, this is an excellent …

Use your Raspberry-Pi to work on this project. You will need a breadboard, an LED, some resistors, and some wire for this homework. In class I handed out some female/male hookup wires for connecting the Pi to the breadboard. You should source the remaining parts yourself, although if for some reason you cannot let me …
With its copious number of GPIO pins and native USB, the Raspberry Pi Pico is arguably the ideal microcontroller for developing your own platform agnostic USB Human Input Devices. But you don’t have to take our word for it. Check out how quickly the $4 USD board allowed [Alberto Nunez] to put together a pair of …

Introduction Short description of what was done for the project. The work team has done for the sand flow system is to simulate the motion of sand to realize the sand matrix game on PiTFT screen. The piTFT screen is hand held by users so that users are able to control the flowing direction of …
As you dive deeper into the world of electronics, a good oscilloscope quickly is an indispensable tool. However, for many use cases where you’re debugging low voltage, low speed circuits, that expensive oscilloscope is using only a fraction of its capabilities. As a minimalist alternative for these use cases [fhdm-dev] created Scoppy, a combination of firmware …
