Programming Embedded Systems_With C and GNU Development Tool

Описание: Embedded system requires very diversified skillsets and I don't believe all of them can be covered in one book. In my opinion, the skilset of embedded system programming can be loosely grouped into two categories which are 8-bit and 32-bit. Engineers writing software for 8-bit microcontroller would usually be more involved in hardware details such as keypad debouncing, soft I2C etc. On the other hand, their 32-bit counterpart would spend more time designing more complex software that may includes bootloader, structured programming and RTOS. This book is more appropriate for those who intend to use 32-bit processor i.e. ARM rather than 8-bit microcontrollers i.e. 8051 and PIC.
I had quite some years of experience developing PIC/8051 firmware on Windwos platform, but did not had any experience on Unix. I found the book is particular useful in introducing building project on Unix platform, it is brief, but that's exactly what I wanted - short and simple.
Chapters on hardware, tool chain, memory, interrupts and RTOS are quite fundamental but could come handy to beginner in embedded world despite there are many other books that excel in these areas. However, I found Chapter 7 "Peripherals" is well written to teach you how to write a device driver. I believe this is something new to learn for engineers with either software or hardware background. Hardware engineers tend to access the hardware registers directly. On the other hand, softawre guys may not be familiar with low-level hardware. The authors talked about the device driver philosophy and elaborate on how to use struct and bitfield to provide hardware abstraction. Finally, a serial port device driver is presented as an example.
As a conclusion, this is a very good introductory book to 32-bit embedded programming, or better still if you use Unix/Linux/eCOS. For those who want to learn deeper about RTOS and hardware (say, how to write soft I2C, keypad/button debounce, LCD driver), you wouldn't gain much from this book.
