摘要
针对野外恶劣使用环境,设计了一种环境适应性强的显示控制系统。该系统采用基于DSP和S1D13305控制EL显示屏的设计方案,从软硬件两方面阐述了DSP和显示控制芯片之间的接口电路和设计方法,解决了显示控制芯片内部字库内容单一的问题,并给出了系统设置和显示控制芯片初始化程序,开发了显示驱动模块。经过实战考核和应用,该显示系统在野外恶劣环境中工作稳定,显示效果良好。该显示系统达到了预期效果。
An environmental adaptability display control system was designed for the wild harsh environment.The system is based on the design of the EL screen controlled by DSP and S1D13305.Both the interface circuit and software design methods between DSP and display control chip were discussed.The problem that the internal character content of the display control chip is single was solved.The initialization procedures of the system settings and display control chip settings were provided.The display driving module was developed.After the actual assessment and application,the display system in the wild harsh environment is stable,and has better display quality in actual use.The display system can achieve the desired effect.
