Creating I2C device drivers

Communicating with devices in Linux happens at different levels. The most basic layer of drivers is the kernel module. Among other things, these modules have unrestricted access to the operating system and, if necessary, provide access to users via interfaces such as block devices. This is where the I2C (https://learn.sparkfun.com/tutorials/i2c/all) driver offers the as /dev/i2c-1 bus (for example) that you can write to and read from. Using Rust, we can use this interface to create a driver for a sensor device that is connected to that bus. Let's see how that works.

How to do it...

Device drivers can be implemented in a few steps:

Create a binary project: cargo new i2cdevice-drivers
Open the...

Claus Matzinger

Claus Matzinger

Claus Matzinger is a software engineer with a very diverse background. After working in a small company maintaining code for embedded devices, he joined a large corporation to work on legacy Smalltalk applications. This led to a great interest in programming languages early on, and Claus became the CTO for a health games start-up based on Scala technology. Since then, Claus' roles have shifted toward customer-facing roles in the IoT database-technology start-up crate.io and, most recently, Microsoft. There, he hosts a podcast, writes code together with customers, and blogs about the solutions arising from these engagements. For more than 5 years, Claus has implemented software to help customers innovate, achieve, and maintain success.

Network Programming with Rust

Network Programming with Rust

Rust has steadily become one of the most important new programming languages in recent years. One the one hand, it is low-level enough to provide fine-grained control over memory while providing memory-safety through compile-time validation. Rust also guarantees data race-free parallelism. All these features make it uniquely suitable for writing low-level networking applications. This book will help developers get started on writing such applications in Rust.
