In this third and final part of the project about the Game Boy serial communication I will explain how I managed to print on the Game Boy Printer from my PC using an STM32F4 as the bridge between the two. The encoding of the image into Game…
In this second part of the project about interfacing the Game Boy serial communication with an embedded development board I will explain how I built a Virtual Game Boy Printer. The embedded board will be simulating a real Game Boy Printer,
In these series of blog posts I will write about the Game Boy serial communication protocol and how to interact with it by using an embedded development board. The code for the development board will be written in C, and the code running on…
I’ve recently acquired a handheld ARM computer with screen and keyboard called the PocketCHIP. The main board on the device is called the CHIP, which is a tiny ARM computer capable of running Linux that is sold for $9. After flashing it wit…
This post describes the upgrade procedure I follow to upgrade my Raspberry Pi Alpine Linux installation. Alpine Linux on the Raspberry Pi runs from ramfs and thus the upgrading is not straightforward. Most of the details are taken from the
