有关芯片8253/8255/8259的程序

Part IV In part II we discussed the conversion of binary numbers into decimal digits. It is sometimes useful to build circuits that use this method of representing decimal numbers, in which each decimal digit is represented using four bits. This scheme is known as the binary coded decimal (BCD) representation. As an example, the decimal value 59 is encoded in BCD form as 0101 1001. You are to design a circuit that adds two BCD digits. The inputs to the circuit are BCD numbers A and B, plus a carry-in, cin. The output should be a two-digit BCD sum S1S0. Note that the largest sum that needs to be handled by this circuit is S

Trolltech公司发布的基于C++图形开发环境，支持大量的API，是Linux下的图形界面开发利器。这是较早的版本，但在嵌入式系统的移植比较成功！-Trolltech released on C graphical development environment to support a large number of API, is the Linux GUI development of weapon. This is an earlier version, but in the embedded system more successful transplant!
