Developing with Embedded Linux®

Introduction

Embedded Linux^® is a popular choice for microprocessor (MPU) development. It is much more than just an operating system. It is a large collection of software libraries, device drivers, networking stacks, software applications, and tools to choose from. There are thousands of developers contributing to its open-source model. And there is a large online community providing tutorials and answering questions in forums to aid the developer.

Browse our selection of educational resources to learn more about how you can develop your next Embedded Linux project with Microchip’s 32-bit MPUs.
