PSDE 是一套建立在Microsoft Visual C++环境之上的PDA软件开发平台，在PC上编译输出PDA的完全仿真软件，PSDE的目标是应用Microsoft Visual C++强大的开发环境开发出适用于特定PDA硬件平台编译器的标准C语言代码，同时输出PC上的仿真软件，以用于配套的电脑联机软件或演示程序等，避免了PDA开发厂商为了联机软件或演示程序而单独开发新的程序。PSDE能模拟的硬件功能有ROM、FLASH、LCD、触摸屏、按键、中断、硬复位、声音、CPU休眠等，涵盖了目前常用的大部分PDA硬件功能。

-PSDE is a set built on the Microsoft Visual C　　 environment on PDA software development platform in the PC on the compiler output PDA complete simulation software, PSDE goal is the application of Microsoft Visual C　　 powerful development environment for the development of specific PDA hardware platform compilers browser s standard C language code, while the output on the PC emulation software for supporting computer software or an online demonstration of procedures to avoid the development of PDA manufacturers to online software or demo program and a separate development of new procedures. PSDE can simulate the function of the hardware ROM, F
