Well, it is not a book for experienced hardware engineers. But it is a Great book for the programmers in the embedded system team.
The author short introduce the basic of electronics, power, and SPI bus, I2C bus, UART serial port in the beginning. Unfortunately, he talks too little of IrDA, USB, CAN bus in the middle of this book. Though the ICs he used is seldom seem in Taiwan, and you cannot establish a embedded system after reading it. Anyway, it is very useful for the programmer to know the business of the hardware engineers. I think the programmers should got one.
I love the latter of this book. The author briefly introduce (Microchip) PIC, (ATMEL) AVR, (Motorolla) 68HC11, (Dallas) MAXQ, (Motorola) DSP6800/68000 CPU from chapter 14 to 19.
Most important is that he Clearly explain what the "memory management unit (MMU)" exactly be done in the electronic element and scheme. Most software programmer learn the MMU from Linux kernel -system call, and have no idea of what it works in the electronic scheme/ICs. The author show you these things quite frankly.
It is great!
