基于ucguiII嵌入式系统和STM32的一个完整源代码，经过简单修改即可和自己的CC2530开发板通过串口通信，从而实现诸如读写cc2530数据，控制cc2530无线收发的功能。STM32本身（代码自带的系统）是一种传感器（以cc2530为基础）的控制系统，可以设定传感器工作的间隔，显示格式，日期等等功能。

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
