In this series of posts, I’m attempting to make a Dual Shock to Switch controller adapter. It will plug into the Switch Dock’s USB port.

This is a bit of an interlude from actually working on the project: in this post, I put a serial bootloader onto the ATmega8A I’m using, to make development more efficient.

Last time, I got the ATmega masquerading as a Pro Controller and controlling the Switch. This time debugging and performance improvements!

In previous posts, I got a breadboard with an ATmega8A on it running code I wrote using V-USB, masquerading as a generic USB HID game controller when plugged into a computer.

By the end of this post, it will control a real Nintendo Switch! Scroll down to the video at the end for a sneak peek if you’re impatient.

Last time, I ended with a real USB device that would communicate with a host computer - but all it would do is blink a light on and off.

In the first post of this series, I got a development environment set up, a programmed ATmega8A onto a breadboard, and code I wrote controlling a blinking LED. In this post, I plan to get V-USB set up, and an LED blinking on a breadboard - OVER USB!

In this series of posts, I’m going to (attempt to?…) make a Dual Shock to Switch controller adapter. It will plug into the Switch Dock’s USB port.

In doing this, I hope I’ll learn about how USB works - something I’ve vaguely wondered about for at least twenty years - and have some fun doing low-level microcontroller programming.

I’m also looking forward to stretching my writing muscles documenting the project here. Maybe you can learn along with me?

I find Extremely Linear Git History (GitHub) unreasonably amusing.

It’s also unreasonably easy to install with HomeBrew (brew install zegl/tap/git-linearize) - so I just had to give it a try out when initializing a new project.

This led me into a huge detour. Just what was it doing to my Git repo to get the linear hashes?

Come on a journey with me!

For over a year now, I’ve been using an MSI Prestige PS341WU as my main display. It plugs into my MacBook (now, an M2 MacBook Air of my own, previously mostly a 16" M1 MacBook Pro from work).

At the time I bought it, it was about the only reasonably priced ultrawide that also stood a chance of being considered ‘retina’ - and a casual browse around now seems to indicate that is still the case.

The blog is back! Eight years and one month after the last post (wow!)

What have I been doing? Working for Apple, mostly. From April 2014 to July 2022 I worked on the UIKit team, for most of that time managing the UIKit Infrastructure sub-team - a wonderful bunch of people. It was (mostly) great - and, as is often true, somehow seems like something I did for ever for ever, and something that started only yesterday.
