一、概述采用ST7920驱动的液晶模块,具备丰富的与MCU的接口,可采用并行或串行方式进行通信;带有16×16的中文字库、16×8的字符字库,可以显示半宽的HCGROM字型、CGRAM字型以及中文CGROM三种字型,通过在DDRAM中写入的编码选择,大大方便了用户的编程应用。ST7920具备丰富的功能,可方便实现各种显示,但其自身带有的反白指令,一次只能将液晶屏上的一、三行或二、四行同时进行反白,无法任意位置的反白效果,一时曾让不少用
First, an overview of the use of ST7920-driven LCD module, with a rich interface with the MCU, you can use parallel or serial communication; with 16 × 16 Chinese character library, 16 × 8 character font, you can display half-width HCGROM Fonts, CGRAM fonts and Chinese CGROM three fonts, encoded in the DDRAM to write the code, which greatly facilitates the user’s programming applications. ST7920 has a wealth of features that can easily achieve a variety of displays, but its own anti-white instructions, one can only be on the LCD screen, one or three lines or two lines at the same time anti-white, can not be anywhere in the anti- White effect, sometimes let a lot of use
