Arduino Zero (SAMD21) FDPLL with CMSIS
One of the coolest, tucked-away features in the SAMD21 is the fractional digital phase locked loop (FDPLL). I still only have a vague idea of how phase locked loops (PLLs) work, but nonetheless, we can use the SAMD21’s PLL to create a 96 MHz clock. The bad news is that, to the best of my…

Arduino Zero (SAMD21) Raw PWM Using CMSIS
Arduino has a habit of making pulse width modulation (PWM) pins with a set frequency (or limited frequency options). For the average user, this is not a bad thing, considering it hides all the ugliness (or beauty, depending on your perspective) of manually setting registers. For those of us that want to dig deeper into…

Arduino WebSocket Server Using an ESP32
WebSockets is an incredibly useful protocol that lets you send data to and from a server over TCP without the need for HTTP. Importantly, it lets you push data from the server to a client (e.g. a browser) without needing to make a request. This can be very handy for things like browser-based multiplayer games.…

Getting Started with Phaser Part 3: Sprites and Movement
In the last part, we added the Phaser framework to a web page and said “hello” on a canvas element. In this part, we create a simple sprite (a ball) and move it around the canvas. Why a ball? I consider it to be a test of whether gaming is possible on a particular platform. In…

Getting Started with Phaser Part 2: Drawing Text
In the first part, we created a simple web server and page. We didn’t even touch Phaser! However, that is about to change. In the second part of this series, we create a game area in an HTML div and draw some simple text on it using Phaser. Directory Structure In your Games directory, create another…
