1.8-inch SPI serial port 128*160 Instructions /* Program default IO connection method: sbit LCD_CS =P0^0; //chip select sbit LCD_AO =P0^2; //data/command switch sbit LCD_SDA =P1^5; // Data sbit LCD_SCK =P1^7; //clock sbit LCD_REST =P0^1; //reset */ ●TFT power supply: screen power supply is 2.8-3.3V; remember not to use 5V (modules with PCB have inherited 3V regulator IC , 5V can be input) ●Backlight power supply (LED pin): The maximum backlight power supply is 3.2V. (5 ohm current limiting resistor can be connected in series under 3.3V power supply or 25 ohm resistor in series under 5V).
