| Abstract: |
| [Objective] In order to make embedded system software fit different kinds of communication protocol and remain the stable of communication module, universal serial port driver is designed.[Method] Base on the ARM LPC2132 microprocessor chip, we propose the design of universal serial port driver. We separate the communication protocol from port driver and classify the protocol frame data segment. Therefore, the system only needs to define the description of protocol frame data segment. Real-time communication can be realized without communication with specific universal driver.[Result] This serial port driver is tested and applied stably in remote acquisition environment for a long time. [Conclusion] This serial port driver increases the efficiency of coding and simplifies design for driver software. |
