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

本项目的目标设计微控制器操作的架子鼓和吉他，只包括鼓棍，脚踏板，并选取。这是通过执行连接到单片机的加速度计。由摇摆的棍子和在空气中挑选吉他你可以玩鼓和吉他演奏。我们还实施了回放功能你可以记录声音和稍后听听它。摇滚乐 ！
