What You’ll Find In This zyBook:

More action with less text.

  • Teaches the discipline of embedded programming, independent of any particular device
  • Emphasizes capturing behavior with a computation model (state machine)
  • Students write their own task scheduler in C (basis of RTOSes)
  • ~400 participation activities: Questions, animations, tools
  • Browser-based tools include SM capture, PID simulator, and more
  • Accompanies the RI Tools suite (Windows): C programming, emulation, state machine capture; good for additional homework
  • Can be used for classes with or without a physical device-specific lab

The zyBooks Approach

Less text doesn’t mean less learning.

Teaches a lasting discipline of embedded programming independent of a specific device. The material emphasizes concurrent synchronous state machines for robust real-time programming. Behavior is captured as C-based synchronous state machines, and then converted to structured C code intended for a microcontroller. To teach principles, the material is accompanied by the (Windows-based) RI toolset consisting of a graphical virtual microcontroller with embedded C compiler/debugger, a state machine capture tool, and a timing diagram viewer. The RI Tools enable in-depth mastery of principles without distraction of microcontroller-specific details.

“I have now been asked to teach Discrete Mathematics again … because of my past experience with zyBooks I agreed to teach this topic again only if I could use the zyBook again.”
