Circuit Break Podcast #415: CI/CD, We Salute You with Brenden Duncombe

Podcast Title: CI/CD, We Salute You with Brenden Duncombe

Episode: #415

This week Parker and Stephen welcome Brenden Duncombe to the show to discuss the pros and cons of continuous integration and continuous delivery/deployment (aka CI/CD) for hardware. Continuous integration (CI) refers to the practice of automatically and frequently integrating code changes into a shared source code repository. Continuous delivery and/or deployment (CD) is a two-part process that refers to the integration, testing, and delivery of code changes. In theory, CI/CD helps organizations avoid bugs and code failures while maintaining a continuous cycle of software development and updates, but we wanted to learn more about this with Brenden, so Parker and Stephen asked him about CI/CD, and also covered topics like:

Great episode! I moved from C to embedded Rust a couple years ago and apart from the obvious language benefits, the quality of the tooling has been the biggest game changer for me. We also use HIL tests at the framework/HAL level in embassy in CI/CD via teleprobe

Nice to hear that other people are attempting this process with hardware!
