Since the publication of the Agile Manifesto back in 2001, Agile practices have become mainstream in software development with processes such as Scrum and techniques such as Test-Driven Development (TDD) becoming common practice.
However, almost all current books and training on Agile ignore the challenges of applying it in an embedded C environment. Aspects such as aligning Agile with hardware and mechanical teams, testing on the target, hardware dependency and managing both host and cross-compiler toolchains are generally ignored or over-simplified.
The course attempts to provide a pragmatic introduction to Agile practices, such as Scrum, and techniques, such as TDD, within the context of Embedded Systems.
Attendees perform practical exercises using both host (Linux / gcc) and cross-development (Cortex-M / arm-none-eabi-gcc) toolchains supported by a modern build system (SCons) and configuration management (Git) tools.
The course also looks at modern Continuous Integration (CI) with Docker containers.
- To understand the principles of Agile Software Development
- To appreciate Agile for Embedded is different from Agile for non-Embedded
- To identify the tools required to support Agile Software Development
- The gain practical experience of applying Agile principles to an Embedded system
- The challenges and pitfalls of applying TDD to an embedded system
Delegates will learn:
- How to cherry-pick appropriate Agile practices
- The principles of Scrum and Lean
- How to practice Test-Driven Development with version control (Git)
- How far Continuous Integration (CI) can be applied to embedded software development
- Why moving to ‘Agile’ can be difficult
- Attendees should have a good working knowledge of the C language
- Have experience of developing software for embedded systems
- Understand the build process (preprocessor-compiler-linker-executable)
Who should attend:
The course is designed for software engineers working on an embedded C project.
The target audience is engineers working in, or looking to move to, an Agile project environment (e.g. Scrum) and who want a pragmatic introduction to Agile process and techniques in the context of writing software for embedded systems.
- Delegate manual
- Delegate workbook
- Delegate bootable Linux datakey with all tools installed
Attendees perform a mixture of hands-on programming for both host and embedded targets. Approximately 50% of the course is given over to practical work.
The host code is developed on Linux using GCC and Scons supported by Git versioning. The embedded code is targeted at an ARM Cortex-M based MCU using arm-none-eabi-gcc.
As part of the course, students are introduced to Docker for build isolation and cloud-based build systems, such as Travis-CI.
This combination gives attendees a real sense of the challenges of applying Agile development to an embedded application.
