Enjoy some old school 3D arcade action — courtesy of the Raspberry Pi Pico

In the mid-1980s, I loved Phantom Slayer. Written for the Tandy Color Computer and made available for the Dragon 32, Phantom Slayer was a 3D maze shooter. Think a very basic version of Doom with colours but no textures. It wasn’t sophisticated, but it was quick and, more to the point, incredibly atmospheric.

Play Hunt the Wumpus, Raspberry Pi Pico style

Here’s something a little different: a basic C project that you can follow to build a fun handheld game with a Raspberry Pi Pico. Your mission: to enter a dark cave, and then locate and destroy the monstrous Wumpus.

Locate and eliminate the monstrous Wumpus to win fabulous prizes… well, a trophy graphic…

How to debug a Raspberry Pi Pico with a Mac, SWD and… another Pico

When you’ve used Serial Wire Debug (SWD) to help you correct the C or C++ code running on your Raspberry Pi Pico, you’ll never want to go back to USB and the UF2 file system again. I don’t — no more messing about unplugging and re-plugging cables for me.

How to program the Raspberry Pi Pico in C on a Mac

Last week I tried the Raspberry Pi Pico with MicroPython. The Raspberry Pi Foundation would be sufficiently commended for providing only this level of programming support. MicroPython leverages the Python skills of the many Raspberry Pi users out there and is accessible to plenty of others too. But the Foundation has also provided a C/C++ SDK, and this opens the Pico up to serious embedded-system developers too.

A first look at a MicroPython marvel: the Raspberry Pi Pico, in partnership with a Mac

On Thursday morning I awoke to the news that the Raspberry Pi people have entered the microcontroller board market with a new product, the Raspberry Pi Pico. Before I’d even got out of bed, I ordered a couple. Well, at £3.60 a pop, why not? I’ve now had a chance for a quick play, and here are my findings.

Look, ma, no SD! Boot a Raspberry Pi from USB only

The Raspberry Pi 4 is now capable of booting from a USB Flash drive without requiring an SD card to kick-start the process. Here’s how you set it up.

A cure for Raspberry Pi ‘Slow USB Mouse Syndrome’

I don’t quite know how I missed this, but I’m guessing plenty of Pi users might have missed it too so here it is. If you’re tired of the Raspbian desktop’s too, too laggy mouse performance, there’s a very easy cure. Poor mouse responsivity was the only thing preventing me from using the Raspbian desktop on a regular basis. Here’s how to fix it.

How to upgrade to the new Nano 5.0 on Mac and Pi

The Nano command line text editor has reached a new milestone: version 5.0.

There are the usual array of bug fixes and tweaks, but what caught my eye among the release notes was the introduction of a scroll indicator. This tells you where you are within a long file and is particularly good for mouse users so you can see where you’ve got to as you mouse-wheel through a document.
