摘要
针对摊铺机人机界面需要显示大量图文信息的问题,提出了一种基于DSP TMS320LF2407A的按键输入和显示输出的软硬件实现方案,设计了DSP与液晶显示控制器SED1330及EEPROM 24LC256的硬件接口电路,重点介绍了利用DSP的数字I/O口来模拟SED1330时序的方法,给出了关键的软件程序,在实际系统应用中取得了成功。
According to plentiful information of graphics and characters needed by the onboard HMI of paver, a realization means of software and hardware is brought forward based on key-press as input and LCD as output controlled by E）SP TMS320LF2407A. The hardware interface circuit among DSP, LCD controller SED1330 and EEPROM 24LC256 is designed, and using digital I/O ports to simulate time sequence of SED1330 is introduced in detail, and key program is given. Finally, it is accomplished in the practical system application.
