STM32CubeMX learning notes (39) -- FSMC interface use (TFT-LCD touch screen)
1, Introduction to TFT-LCD
TFT-LCD (thin film transistor liquid crystal display) is a thin film transistor liquid crystal display. TFT-LCD is different from the simple matrix of passive TN-LCD and STN-LCD. It is equipped with a thin film transistor (TFT) on each pixel of the LCD, which can effectively overcome the crosstalk when it is not g ...

Principle introduction
XPT2046 chip is used in the resistance screen, and its principle is relatively simple: when we touch a certain point, the resistance distribution of X and Y axes will change:
When we touch a point on the next screen, the level of the chip pin will change. At this tim ...
