2014年2月26日 · 经过测试J204A(也称2004A,每行20字符,显示4行)液晶屏和1602液晶屏的. 使用方法几乎是一样的,不过也是有区别的,在1602液晶屏中,用来寄存待显. 示字符代码的DDRAM共有80个字节,而J204A能够一次性显示的字符是80字. 节,这里不是巧合,即J204A只是将LCD1602的DDRAM的80个字符全部显示出. 来而已。 第一行首地址 :0x80. 第二行首地址 :0x80+0x40. 第三行首地址 :0x80+20. 第四行首地址 :0x80+0x40+20. 可以注意到,第一行和第 …
Total of 16 commons and 40 segments signal drivers are valid in the LCD driver circuit. When a program specifies the character fonts and line numbers, the corresponding common signals output drive-waveforms and the others still output unselected waveforms.
【雕爷学编程】Arduino动手做(127)---2004A LCD液晶屏模块
2023年6月25日 · 液晶显示屏(LCD)用于数字型钟表和许多便携式计算机的一种显示器类型。 LCD显示使用了两片极化材料,在它们之间是液体水晶溶液。 电流通过该液体时会使水晶重新排列,以使光线无法透过它们。 因此,每个水晶就像百叶窗,既能允许光线穿过又能挡住光线。 液晶显示器(LCD)目前科技信息产品都朝着轻、薄、短、小的目标发展,在计算机周边中拥有悠久历史的显示器产品当然也不例外。 在便于携带与搬运为前题之下,传统的显示方式如CRT映像 …
