介绍了一般LCD与MCU的接口技术及其抗干扰措施,结合最近开发的绝缘油耐压测试仪中出现的CMOS自锁现象,提出了一种在强电磁场等特殊环境下,可靠使用液晶显示器的技术方法。
This paper introduces the interface technology of general LCD and MCU and its anti-jamming measures. Combined with the self-locking phenomenon of CMOS in the recently developed Insulation Oil Pressure Tester, this paper presents a method of reliably using liquid crystal displays in special environments such as strong electromagnetic fields Technical method.
