AVR硬件设计注意事项,需要在设计中注意-AVRHARDWARE DESIGN GUIDE

利用单片机的定时器定时，令十字路口的红绿灯交替点亮和熄灭，实现主支路路口的交通信号灯控制（尽可能保持主线的畅通，即在通常情况下，保持主线的放行，只有在支线到达时，才放行支线），同时采用LCD显示倒计时时间及当前灯的状态-The use of MCU timer timing, so that the crossroads at the traffic lights turn out light and to achieve the main slip road junction traffic lights control (as far as possible the smooth flow of the main line, that is, under normal circumstances, to maintain the release of the main line, and only arrived at the branch only when the release branch), while using LCD display countdown time and the current state of light

嵌入式开发板搭建最小系统,在嵌入式开发板上，建立内核，文件系统等等，使最小系统能够在其上运行-to build the minimun system on a board, embedded software programms.you can rely on it to impletement the basic function of an embedded system

IC卡操作软件:AT88SCl604芯片的操作模式有五种。它们是通过配PGM、RST、CLK等引脚信号及内部地址计数器(IAC)的状态组合来实现。 (1) 芯片复位操作： AT88SCl604有两种复位方式:上电复位和控制复位。 上电复位： 上电复位是当芯片加电时的最初状态。上电复位属于芯片 内部复位。它将使芯片内部所有的隐含标志复位到"0"状态。并使地址计数器复位到0位。 控制复位： 当CLK为低时，在RST脚上的一个下降沿将便芯片产生复位操作。 控制复位是将地址计数器复位到0位，而不影响任何内部标志的状态。-IC Card operating software : AT88SCl604 chip mode of operation there are five. They are allocated by PGM, RST, etc. pin CLK signal and the internal address counter (IAC) portfolio of the state is to be achieved. (1) chip reset operation : reduction AT88SCl604 two ways : power-on reset and reset control. Power-on reset : power-on reset when the chip is in power at the initial state. Power-on reset the internal chip is reset. It will enable all internal chip implied signs reset to "0" state. Make address counter reset to 0. Reset control : When the CLK for the low, the RST feet of a falling edge chips will have to reset operation. Reset control is to address counter reset to 0, without prejudice to any signs of internal sta
