| Abstract: | In present, there are many interface cards of CAN bus through ISA and PCI, they are not easy to test in field. EPP is a bi directional data communication protocol of enhanced parallel port, it has performances of high speed and easy extensibility, which is provided by luggable computer. The paper analyzes the work feature of EPP and implements the protocol conversion of EPP interface with GAL device. The circuit schematics and software implement of EPP CAN controller is presented in this paper. In the same time, the several key technologies are explained in the design. |
