Memory and timing become direct programming concerns on a microcontroller. Freescale ARM Cortex-M Embedded Programming Using C Language, by Muhammad Ali Mazidi and his coauthors, connects C fundamentals with that hardware context.
Programming the Device
The book covers embedded C for Freescale ARM Cortex-M devices, including memory maps, memory-mapped registers, interrupts, and timing. A register description becomes part of the interface the program must implement.
The examples make the connection between a C operation and device behavior easier to follow. Correctness includes producing a value at the appropriate time, while limited memory and visibility into the running system reward clear structure.
Prerequisites and Hardware Context
Basic C knowledge provides a useful starting point. Device-specific examples must be checked against the board's manual. The book's broader value is the habit of tracing software behavior down to hardware, which remains useful beyond one microcontroller family.
