| Abstract |
Previously, in order to send information from the local controller to the display board, the hardware or software had to be handled and run through 3-phases, which include the PC-card or PC-add Board, I/F card and Sub board. This study will attempt to design a board that handles information by connecting the USB port of the PC directly to the Sub board. In addition, an MPU will be attached to the previously complex hardware circuit to design a software drive engine module, which allows for the development of new products by modifying only the software engine and not the hardware. |
