| 摘 要： | TI公司TMS320F2812型DSP广泛应用于电机电力等工业控制领域,eCAN通信以其抗干扰能力强,高效、灵活、为恶劣环境下现场通信的首选方式。本实验将DSP设置为中断方式接收信息,设备工作后DSP首先向上位机发送一串代码,表示设备准备好等待接收信息,当上位机向DSP发出指令后,DSP即以中断方式接收信息,并将信息回传给上位机,实现DSP与上位机的双向通信。

| Abstract: | TI's TMS320F2812-based DSP have been widely used in electrical power and other industrial control areas,The eCAN communications with its strong anti-interference ability,efficiently and flexiblity,which are preferred method of field communication in the harsh environment,The data receivation of DSP is set in interrupt mode,and a command is send to upper computer on initialization to indicate that the DSP is ready to receive information.The DSP will receive the command in interrupt mode and send it back to t... |
