Instructions
Program default IO connections:
sbit LCD_CS = P0 ^ 0; Chip Select
sbit LCD_RS = 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: Screen Power is 2.8-3.3V; remember not to use 5V
(Modules with PCB’s have inherited 3V regulator IC, you can enter 5V)
backlight power supply (LED pin): 3.2V maximum backlight power
(At 3.3V supply can be connected in series for 10 ohm current limiting resistor in series with 100 ohms or 5V Resistance).
Data port level: theoretically can not let the data port level exceeds 3.3V, if you must
IO connection with 5V microcontroller data bus, as tft internal voltage clamp, with
Can be used, but is not always standard. You can do an experiment to test a sample batch
Made product, in order to improve product stability, better use of low-voltage monolithic
Machine or add a level converter IC.
