Embedded Software Conferences

I am an avid conference attendee, speaker and organizer, but all in the area of software development and testing for cloud-based software.

My colleagues have reached out to me in search for interesting conferences that focus on embedded software development (in C), testing and quality, but I came up pretty empty handed.
