Design of CAN Bus Adapter Based on DSP |
| |
| Abstract: | Based on Tl＇s DSP TMS320LF2407A,a design method of bus interface and protocol conversion in RS232,RS485 and CAN bus is described.The communication is also realized in these universal serial buses.The functions,hardware circuits,software design and flow charts are given in this paper.A method of the connection in different buses and construction bus network is provided by the network interface in the adapter. |
