Part III Figure 2a shows a circuit for a full adder, which has the inputs a, b, and ci, and produces the outputs s and co. Parts b and c of the figure show a circuit symbol and truth table for the full adder, which produces the two-bit binary sum cos = a + b + ci. Figure 2d shows how four instances of this full adder entity can be used to design a circuit that adds two four-bit numbers. This type of circuit is usually called a ripple-carry adder, because of the way that the carry signals are passed from one full adder to the next. Write VHDL code that implements this circuit, as described below. 2

Led matrix display sample for 89C51 with 74HC595

将AT PS2键盘连接到公共接口的代码：9600波特的串行端口输出，带选通的并行输出或带就绪信号的SPI端口。最初的代码是68HC705J1Ahttp://retired.beyondlogic.org/keyboard/keybrd.htm但我把它移植到了Atmel ATtiny48上，增加了对SPI接口和并行输出的支持，增加了对更多键的支持。ATtiny48使用内部振荡器，只需连接器即可工作。

应用背景3280led点阵时钟，08接口，支持市面上大部分08接口的双色点阵，3264可以相应修改关键技术3280 led 点阵时钟，08接口。淘宝有很多相似的点阵版，基本都能用。。。

应用Atmel Atmega128L单片机，循环采集外部六路数据，并且通过串行口发送到上位机，采样率很高。-Applications Atmel Atmega128L microcontroller, an external six-channel data acquisition cycle, and through the serial port to send to the host computer, the sampling rate is high.
