Controller design suitable for LCD display
With the continuous development of display technology, true color LCD screens have gradually occupied an important position in embedded display systems with their advantages such as high resolution, high contrast and high definition. At present, there are two main ways to implement LCD display control technology based

12864 LCD menu design
Why is the menu called a menu? I can't find the reason anymore. I'm afraid I'll be scolded if I throw out a bunch of old papers and list a bunch of opinions on this issue. Whether you admit it or not, the concept of menu has penetrated into every aspect of our lives with the popularization of computers. Many things ca

In-depth understanding of ARM architecture (S3C6410) --- LCD display picture
The S3C6410 display controller contains logic circuits that transfer data from the local bus of the post processor or system memory video buffer data to the external LCD driver interface circuit. The S3C6410 contains 4 interfaces: traditional RGB interface, I80 interface, standard TV encoding interface NTSC/PAL, IT-R B

STM8L152 LCD module principle and driver
The STM8L182 integrates a driver module for an LCD with up to 320 pixels. The block diagram is as follows: 1. Configure the LCD clock source, division ratio, duty cycle, offset voltage, enable LCD port multiplexing function, definition, and enable LCD function. void LCD_Config(void) {     /* Enable RTC CLK */
