摘要
论文介绍了DSP芯片TMS320F2812的功能特点和液晶模块HS12864的特性,给出了TMS320F2812与液晶模块的接口电路。最后,根据显示模块的指令特点,将液晶屏网格化,简化了多菜单的显示程序,并在此基础上,写出了CCS环境下的C语言程序,实现了在TMS320F2812控制下的谐波谱线的显示。
This paper has introduced the function characters of DSP chip TMS320F2812 and the features of liquid crystal module HS12804, the interface circuit of TMS320F2812 and the module has been given. At last, According to the instructions of display module, the screen is meshed and the multi-menu display programming is simplified, based on this , gets C language programming in CCS environment, and realizes the display of harmonic spectrum under the control of TMS320F2812.
