To connect the Surenoo STP0240C2-240320 Series TFT LCD Panel to your MCU, you will need to use the MCU parallel interface. The LCD panel has a total of 16 data bus pins (DB0-DB15) that need to be connected to the corresponding data bus pins on your MCU. Additionally, you will need to connect the following pins:
1. GND: Connect this pin to the ground (GND) of your system.
2. VDDI: This pin is the power supply for the I/O system and should be connected to a voltage between 1.8V and 3.3V.
3. CSX: This pin is the chip selection pin. When pulled low, it enables the LCD panel. When pulled high, it disables the LCD panel.
4. DCX: This pin is used to select between display data and command data. Set it to '1' for display data and '0' for command data.
5. WRX: This pin is the write enable pin in the MCU parallel interface.
6. RDX: This pin is the read enable pin in the 8080 MCU parallel interface. If not used, you can connect it to VDDI or GND.
7. XL(X-), YU(Y-), XR(X+), YD(Y+): These pins are used for touch panel functionality. Connect them according to your touch panel's logical foot configuration.
8. LEDA: This pin is the anode of the backlight and should be connected to a voltage between 2.9V and 3.3V.
9. LEDK1, LEDK2, LEDK3, LEDK4: These pins are the cathodes of the backlight and should be connected to the corresponding cathodes of your backlight.
10. TE: This pin is the tearing effect signal used to synchronize the MCU to the frame memory.
11. RESX: This pin is used to reset the device. It should be pulled low to properly initialize the chip.
12. VDD: This pin is the power supply for the analog, digital system, and booster circuit. It should be connected to a voltage between 2.8V and 3.3V.
13. VDDI: This pin is the power supply for the I/O system and should be connected to a voltage between 1.8V and 3.3V.
14. GND: Connect this pin to the ground (GND) of your system.
15. DB4, DB5, DB6, DB7: These pins are additional data bus pins in the MCU parallel interface.
Please refer to the Surenoo STP0240C2-240320 Series TFT LCD Panel User Manual for more detailed information on pin configurations and electrical connections.
