VS1003解码芯片的第七和第八章中文翻译，对开发VS1003非常有帮助。

proteus仿真的三个例子，proteus与keilc联调有参考，用C和ASM两种语言实现-Proteus simulation of three examples, proteus and the FBI have keilc reference, using C and ASM languages realize

在上面的电路图，AT89C52 用于模拟指示灯闪烁代码。您可以放置 AT89C51 在这里没有任何其他的变化和代码仍将运行相同。因此，此示例代码可以处理 AT89C51 和 AT89C52 的微控制器。 这里使用 11.0592 MHz A 晶体。你可以使用 8051 的任何晶体值从 3 到 24 兆赫。正如我们所知 8051 微控制器有一个建筑，在 12 个 CPU 周期执行一条指令，因此这种 11.0592 Mhz 晶体使此 8051 的运行在 0.92 MIPS (百万指令每秒)。此项目的代码如下所示。

The PCF7991AT is a fully integrated Advanced Basestation IC, ABIC, designed for car immobilizer systems providing read and write access to an identification transponder. The device is intended for use with the NXP transponder family (PCF79xx) as well as other transponder types operating at 125 kHz and employing ASK, Amplitude Shift Keying for write and AM/PM for the read operation. The receiver characteristics (amplifier gain,filter cutoff frequencies) can be optimized to system and transponder requirements. The PCF7991AT IC is designed for easy integration into immobilizer read/write and read-only systems featuring a high degree of integration and very low external component count. The device integrates a powerful antenna driver/modulator, a low-noise adaptive sampling time demodulator, programmable filters/amplifier and digitizer, required to design high-performance basestations. A three wire microcontroller interface is provided for programming the PCF7991AT as well as for th
