TMS320F2812 DSP与PC机的串口通信设计（国外英文资料） Based on TMS320F2812 DSP communication design with PC [author: wang jing rui jing: the number of clicks on microcomputer information: 181 update time: 2008-11-20 [font: A] Serial Communication between the TMS320F2812 DSP and PC ABSTRACT: This paper introduces the circuit connection between the TMS320F2812 DSP and PC. Then, a serial communication program design of the PC and DSP is provided, which USES the Modbus protocol, To improve the ability of suppressing interference, the communication does not only make use of odd parity and CRC parity, but also apply To the overtime alarm mechanism. KEY WORDS: DSP and PC, serial communication, the design Abstract: this article first introduces the hardware connection of TMS320F2812 DSP for serial communication with a PC. It then elaborates the software design of the communication module of the machine and the host communication module. The protocol for its communication protocols adopted a generic industrial standard Modbus protocol. The system not only USES the odd check and CRC check, but also USES the timer to set the timeout alarm mechanism to improve the communication systems ability to resist interference. Keywords: DSP, PC, serial port communication, design 1. Introduction Typically, microprocessors are integrated with one or more hardware UART channels that facilitate serial communication. In areas such as industrial control, electrical communication, and smart meters, the use of simple and easy-to-use serial communication methods is often used as a means of data exchange. This paper introduces the communication between the electric self-discharging vehicle controller and the fault diagnosis machine using DSP chip. One feature of the electric car dump controller is the ability to collect and upload real-time data and fault data from the electric car to a troubleshooting machine. The fault diagnosis machine (PC) completes the dump, data management and fault diagnosis of the vehicle da
