Electrical Specifications

•Note 1: Input voltages exceeding the maximum or improper operation may cause permanent damage to the device.
•Note 2: The input current needs to be ≥ 2A, otherwise it will cause the startup failure or display abnormality, and staying in an abnormal state for a long time may cause permanent damage to the device.
•Note 3: Please do not store the display panel in a high-temperature and high-humidity environment for a long time. The display panel should operate within its limits, otherwise it may be damaged.

Usage Instructions

Luckfox-Omni3576

Hardware connection

1. Use a 22PIN FPC cable to connect the DSI interface of the display to the DSI interface of the Omni3576 motherboard.
2. Use a 2PIN power cable to connect the power interface of the display to the 40PIN GPIO interface on the Omni3576 motherboard. As shown in the figure below:

Software settings

1. Download and use the mirror file from the Luckfox official website to burn the corresponding system image.
2. Connect the Omni3576 motherboard to a 5V power supply, and the screen will light up after the system starts

View screen information

• The screen ID available in the current system can be viewed using the following command:
  

sudo cat /sys/kernel/debug/dri/0/summary

• Under normal circumstances, the following output will be obtained:

Display rotation

• Rotation command

#Rotate 90 degrees
xrandr -o left
#Rotate 270 degrees
xrandr -o right
#Rotate 180 degrees
xrandr -o inverted
#Rotate 0 degrees
xrandr -o normal

• The effect of using xrandr rotation is a one-time and the screen orientation is restored after the system restarts. If you want the device to rotate automatically upon startup, you need to modify the configuration file:

sudo vim  /etc/X11/xorg.conf.d/10-monitor.conf

Add the following statement:

### Valid values for rotation are "normal", "left", "right"
Section "Monitor"
#    Identifier "Default Monitor"
    Identifier  "DSI-1"
    Option      "Rotate" "left"
EndSection

Touch rotation

• After the system displays rotation, the touch direction is inconsistent, and you need to perform the following operations to touch and rotate:

sudo vim  /etc/udev/rules.d/99-luckfox-touch.rules

• Add the corresponding configuration according to your rotation direction, save it, and restart the development board.

90 degrees:
ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 -1 1 1 0 0"
180 degrees:
ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="-1 0 1 0 -1 1"
270 degrees:
ENV{ID_INPUT_TOUCHSCREEN}=="1", ENV{LIBINPUT_CALIBRATION_MATRIX}="0 1 0 -1 0 1"

ESP32-P4

Screen driver

The ESP32-P4-NANO drives the screen via MIPI 2-lane

1. The screen driver has been packaged as a component, with the component located at ESP Component Registry
   Use idf.py add-dependency "waveshare/esp_lcd_jd9365_10_1" to add components to your ESP-IDF project
2. You can also directly view the ESP32-P4-NANO driver for this screen on the Wiki: ESP32-P4-NANO_MIPI-DSI

Backlight control

After connecting the ESP32-P4-NANO with the matching FPC cable and power cable, the backlight can be controlled by writing 0x00~0xFF (full brightness) to the 0x45 device and 0x86 register on the screen through the ESP32-P4-NANO I2C

If you use the ESP32-P4-NANO BSP component, you can control it directly by the following functions

bsp_display_brightness_init();   // Initialize the backlight

bsp_display_backlight_on();      // Turn on the backlight, default full brightness

Bsp_display_backlight_off();      // Turn off the backlight

bsp_display_brightness_set(95); // Set the specific backlight brightness, 0~100
