MCU drives 19264 LCD to display Chinese characters C program-EEWORLD

Collect

19264 LCD is a monochrome LCD slightly larger than 12864. Here I will introduce to you the principle of using STC series microcontroller to drive it to display Chinese characters.

Why should the microcontroller driver be set to low level valid?

Question: Are peripheral circuit designs and programming of single-chip microcomputers mostly driven by low-level effective circuits?
