摘要
在一个以DSP为主控芯片的频谱分析仪系统中,需要用到键盘、显示器作为系统的输入输出设备,这就要与DSP的I/O口打交道。介绍了TMS320VC5410的通用I/O口资源配置情况,以EPSON的液晶显示器和软件控制键盘输入为例,给出了相应的接口电路和软件驱动程序的设计。
In a system of spectrum analyzer controlled by DSP master, the keyboard and display are needed to be the input and output equipment, which will be connected with I/O interface of DSP. The article introduces the resource configuration in general I/O interface of TMS320VC5410. Taking the LCD screen in EPSON Company and keyboard input by software control as examples, the article lists the relevant design of interface circuit and drivers.
