system programmer
2.This paper introduces how to develop a set of Particles System Application Programmer Interface(API) which can be used to simulate dynamic scene in VR system as a module.
4.However component GIS technology has easy to realize system alete integration, development language diversity, well expansibility, powerful retroactivity, fashionable visualization programmer style characteristics, so much more press close to actual demand of almost GIS users, have powerful life-force.
5.It is compatible with the industry-standard 80C51 instruction set and pinout. The 8K Bytes on-chip downloadable Flash ROMs allows the program memory to be reprogrammed In-System through an SPI serial interface or by a conventional nonvolatile memory programmer. It can fully static operate at 24 MHz.
6.This system contains all necessary control and data circuitry to interface with CRT, standard ASCII keyboard, matrix line printer, EPROM programmer, dual single side double density floppy disk drive, cassette tape recorder, etc.
7.Programmer can add remarks, names of input or output devices, and comments that can be useful when finding errors, or with system maintenance.
8.By comparing WinCE to Linux and VxWorks, this paper draws the conclution that WinCE has the power of network connections and real time and EVC its software developing kit sustains MFC class libraries. These can support the work of developer greatly and make VC++ programmer to enter the developing of embedded application program. Accodingly, I select WinCE and use it as the operation system that EMV terminal appliction runs on.
