System host 11 major feature advantages:
1、Experimental system simulator built 8051; fully compatible with keil C51 UV2 software environment, keil C 
      environment through a single step, breakpoints, full speed, stop, line debugging on the programming, download
      and enforcement operations.
2、Can be easily observed for all variables, including the mouse values ​​observed,   the mouse on a variable that
      will immediately show it on this value.
3、Provides a C language or assembly language for programming ASM original program.
4、8051 system is really USB2.0 burner download, quality is very stable and reliable 480MHz transmission 
      speed transmission interface as the burning program.
5、8051 system uses AT89S51/52 chip, cheap and good buy and easy to use single chip.
6、Activities using 40 PIN module folder.
7、32 I / O port completely Jieke external use.
8、Host system; can be simulated, single-step, 32 I / O ports Jieke external use.
9、Ssystem host using pull approach, so that students can understand the circuit connection, the strict 
      quality control system, even when running the program, the students pull the wrong line error, or anti-plug, or
      plug into other modules, all will not host the failure or damage.
10、Host platform functional specifications using integrated test platform.
11、Aluminum storage box, you can easily test collection device, is not fully protected from damage experiments.
