According to the provided user manual, the Surenoo ST7789V TFT LCD Panel can be connected to your device using either a 4-line SPI, 8-bit, or 16-bit interface. Here is a step-by-step guide on how to connect the panel:
1. Identify the necessary pins: The manual provides a pinout diagram that shows the function of each pin on the LCD panel. Make sure to refer to this diagram to identify the required pins for your chosen interface.
2. Power supply: The LCD panel requires two power supplies - VDDI for the I/O system (1.8-3.3V) and VDD for the analog, digital system, and booster circuit (2.8-3.3V). Connect these power supplies to the respective pins on the LCD panel.
3. Interface selection: Depending on your chosen interface (4-line SPI, 8-bit, or 16-bit), set the IM0, IM1, and IM2 pins accordingly. The manual provides additional information on the specific pin configurations for each interface mode.
4. Data and command selection: If you are using the parallel interface, connect the WRX/A0 pin for write enable and the RDX pin for read enable. For the SPI interface, use the DCX/SPI SCL pin for data/command selection.
5. Data bus connection: Connect the appropriate pins (DB0-DB7 for 8-bit interface, DB0-DB15 for 16-bit interface) to the data bus of your device, depending on the chosen interface mode.
6. Backlight connection: Connect the LED-A pin to the anode of the backlight (typically 2.9-3.3V) and the LED-K pins to the cathode of the backlight.
7. Ground connection: Connect the GND pins to the ground of your device.
8. Tearing effect signal: If required, connect the TE pin to synchronize the MCU to the frame memory.
It is important to note that the specific connection details may vary depending on your device and application. Therefore, it is recommended to consult the user manual and seek professional assistance if needed.
