汽车PKE工程 密钥转发器程序 通过车厂认证的哦
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

TI F24x MCU 三相交流异步电机的V/F控制代码
三相交流异步电机的恒定V/F控制源代码，适用于TI的TMS320F24X MCU，可在TI原装的F24x板上直接跑。
适用于CCS3.3编译、调试环境，可参考向其他芯片进行移植或修改、增加控制算法，实现对三相风机、泵、传送带动力、纺织机传动等控制方面的应用。
程序包括分步递进编译，分成五部分：空间矢量PWM波形发生、电流/转速测量、两相电流的PI控制、电流闭环控制、速度PI闭环控制(电流和速度双闭环控制)。其中包含全部的源码和使用说明指导文档，是学习VVVF控制过程及算法很好的教程和示例。
