电子工业出版社出版的QT4开发与实践例程，该书以Qt4.6作为平台，先介绍Qt平台开发中需要着重注意的C++主要知识点，在简单介绍开发环境的基础上，用一个小的实例，介绍Qt4.6开发应用程序的过程，然后系统介绍Qt应用程序的开发和编程技术，一般均通过实例介绍和理解内容；该资源是各个章节的代码

电子工业出版社博文视点出版的，蔡志明等编著，包括初级篇、中级篇和高级篇，是很好的学习QT4的教材；

The SGM7222 is a high-speed, low-power double-pole/ double-throw (DPDT) analog switch that operates from a single +1.8V to +4.3V power supply.

RK281x is a highly-integrated , high-performance , low-power digital multimedia processor which is based on Dual Core(DSP+CPU) architecture with hardware accelerator. It is designed for high-end multimedia product applications such as PMP ,MID, AP, GPS and Mobile TV etc. RK281x can support decode and encode for various types of video standards such as H.264/RMVB/MPEG-4/AVS/VC1/MPEG-2 by software and dedicated coprocessors. Specially, highest performace for video decode will reach fluent replay for video with H.264 @1280x720 format. RK281x also provides strong graphics/image ability with embedded GPU. By providing a complete set of peripheral interface, RK281x can support very flexible applications , including SDRAM/Mobile SDRAM/DDRII/Mobile DDR, Nor Flash, Nand Flash, LCDC, Sensor, USB OTG 2.0/USB Host 1.0, SD/MMC/SDIO, Wi-Fi, High-speed ADC,I2C,I2S,UART,SPI,PWM etc. This document will provide guideline on how to use RK281x correctly and efficiently. In them , the chapter 1 and chapter 2 will introduce the features, block diagram, signal descriptions and system configuration of RK281x,the chapter 3 through chapter 37 will describe the full function of each module in detail.
