XI Features Benefits:
1. Dual system using the chip; 8051 system AT89S51/52 chip; CPLD system  ALTERA chip is a million logic
    gates or more very large chips.
2. Host system can do 8051 and two CPLD digital logic system that can separate and independent operation of
    the dozens of test modules all can make individual experiments and research projects.
3. 8051 system is really USB2.0 burn download, quality is extremely stable and reliable 480MHz transmission
    speed transmission interface as the burning program, use the chips AT89S51/52.
4. CPLD system uses USB to download, burn, burn the program as the transmission interface.
5. System host by way of cable; so that students can understand the circuit connection, the strict quality control
    system, even in the implementation of the program, students pull circuit line errors, or anti-insert or into the 
    other modules, all will not be the host and the failure or damage.
6. Dual system host platform functions and specifications with an integrated test platform.
7. Aluminum storage box, to facilitate collection of experimental devices, full protection of experimental devices.
8. Hosts frequency generator (frequency switching section 12, the maximum frequency, 100 MHz ~ 1Hz,
    according to different frequency of use).
9. CPLD each I / O Jieyou LED monitor, the user can clearly see that they use the I / O situation.
10. 8051 40pin activities to provide fixtures, 32 I / O ports can add.
11. RS232 converter, to do graphical interface VB, VC internship.
