Abstract

Microcontroller applications usually require low-level drivers for peripheral devices such as I/O ports, interrupts, timers, communication interfaces like UART, CAN [2], SPITM, etc. This chapter presents several efficient methods for programming peripheral hardware drivers in C++. Low-level drivers are inherently dependent on the microcontroller and its peripherals. Even though the low-level hardware drivers in this chapter are primarily designed for our target with the 8–bit microcontroller, an effort has been made to keep them as portable as possible. In this way, they can be adapted to other microcontrollers.

Notes

  1. 1.

    GNU compilers support numerous attributes for functions, variables, objects and types with its __attribute__() syntax. See [1] and [5] for additional details.

  2. 2.

    Note, however, that disabling the interrupts for too long or forgetting to re-enable them in a timely fashion may lead to a system crash with unpredictable results.
