Around five years ago I wrote a Gameboy Color emulator in Go. It was a very frustrating, but rewarding experience that I’ve been dining out on in job interviews ever since.
However, as the passage of time progressed, it landed on the pile of mostly-done-but-not-finished projects and left largely abandoned. One might generously say, on hiatus.
You see, a few weeks ago Go 1.11 came out, and with it came the promise of experimental support for compiling Go code to WebAssembly. There’s nothing one likes more than experimental APIs so this got me thinking, what could I do to test out this new WASM target?
Hello, old friend
Going back to old code is like looking at old photos of yourself. So young, so naive, questionable style. Much to my surprise though, compiling the project using the new WASM target actually worked.
As in, within 5 minutes of commenting out code related to GLFW/GL calls, there was something running in the browser. Obviously, not rendering anything to the page, but there was stuff printing to the developer tools console at least to indicate the emulator was running.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, or even use Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for MakeCode, CircuitPython, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
