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

intrrupt 处理 ind lpc 2148
intrrupt 处理 rtf 文件中通过编程很容易去......
这是一个基本教程上 LPC214x Mcu 和如何编程他们为那些新到的中断的中断。开始时,先让我们看看: 什么中断、 Irq 和 Isr是。根据 wiki:"中断是发送给 CPU 的指示系统事件已发生,需要立即关注的信号"。中断请求,即一个 "IRQ" 可以被认为的特别要求,CPU 要执行一个函数(代码的小片) 当一个中断发生时。此函数或 "小块代码" 技术上称为 "中断服务例程" 或 "ISR"。所以当一个 IRQ 到 CPU 到达时,它停止执行当前的代码并开始执行 ISR后 ISR 执行完毕 CPU 获取回它已停止的位置。
