The development of device drivers and embedded software is full of challenges. But it is possible to write easy-to-read portable C code to control peripherals ranging from simple timers and UARTs to complex custom FPGAs. This important course covers a large number of subjects ranging from C startup code and the “world before main()” to the development of interrupt-based device drivers that interact with peripheral control and status registers through memory-mapped I/O, overlayed structs, and bitfields.
