The LCD screen is JM12864 or FYD12864 (with font library). I have used both models without issues. 4 rows * 8 columns of Chinese characters = 32 serial communication interfaces P1.5–P1.7, which can be modified according to your circuit. #include #define uchar unsigned char void LCD_ini(); void ascii_change(void); void delay(); void wri_add(uchar com); void wri_dat(uchar … Read more
Substrate glass is one of the important raw materials that make up liquid crystal panels. The key structure of a liquid crystal panel is similar to a sandwich, with two layers of ‘bread’ (TFT substrate and color filter) enclosing the ‘jam’ (liquid crystal). Therefore, making a TFT-LCD panel requires two pieces of glass, used as … Read more
The market is seeing an increasing number of smartphones with OLED screens, especially since the iPhone X adopted Samsung’s AMOLED (a branch of OLED). It seems that if flagship phones do not use OLED, they are not considered true flagships. Previously, only Samsung had mass-produced OLED screens for smartphones (Xiaomi NOTE2 used LG’s OLED, which … Read more
Graphic Control Uncle Composition conveys ideas Reading has never been this easy!!! 01 Introduction When developing multifunctional applications for an LCD screen, there are times when you need to clear the screen. Clearing can be done in two ways: full screen clear and partial screen clear. Today, I will document the code for partial screen … Read more
There are many types of LCD screens commonly used, with various interfaces. For example, some are directly driven by the processor, while others are modules with built-in driver ICs. I previously shared about the differences between 8080 and 6800 interfaces in LCDs. Now, let’s briefly summarize the differences between MCU screens and RGB screens, as … Read more
