程序描述:网络远端温度感测器,这个范例中使用到
(1)8051 的Port 1连接到LCD显示器,PORT 3的P3.3、P3.4和P3.5分别连接到LCD显示器的控制线,程序执行时可以让LCD显示器显示出时间和日期。
(2)温度感测组件AD590经由ADC0804将感测到的温度,转换成数位数据,然后经由PORT 0输入8051。
(3)igangcai 8051的第10和第11只脚RXD和TXD分别连线到MAX232,然后连接到PC的COM埠。
(4) 当PC端经由RS232传送S时,接下来PC送出的下 个byte就用来设定PORT 3的输出。
(5) 当PC端经由RS232传送T时,接下来PC连续送出五个bytes,这五个bytes是 "年月日时分",这是 PC 用来设定实验板的时间日期。
(6) 8051每 分钟就读入ADC0804转换的数字温度数据,然后通过RS232传送给PC端,再由PC端通过网络传送到远端的电脑。*/(err)

( On the basis of a conventional matrix converter and a multilevel inverter, a novel multilevel matrix
converter is proposed, and its topology configuration and principle are introduced. This converter operates as a
bidirectional converter and transfers energy between its two sides by charging the midpoint capacitors to a known
constant DC voltage level. Proper selection of control algorithms and capacitor voltages helps synthesize controllable
and waveforms almost sinusoidal three-phases AC voltage with minimum low-order harmonics at both sides of the
converter. The multilevel matrix converter is modeled and simulated with its output controllability discussed.
