As the digital electronic engraving machine needs high speed and credible communication between a host computer and a slave computer, a data communication card for a high speed digital electronic engraving machine is designed and realized using PDIUSBD12 IC and S3C44B0X IC. PDIUSBD12 IC is USB interface device with parallel bus. In the paper, hardware circuit is described, USB driver program is depicted in detail based on the µC/OS-Ⅱ operation system, and the ways and means of debugging the data communication card are given. It has been experimentally validated that the data communication card is applied successfully and works steadily in high speed digital electronic engraving machines.
