DUAL LVDS panel
Personal Computer
Board settings
For DUAL LVDS panel(19201200), connect MINISAS ports J15 and J16 to panel. For LCD SPEC panel(1280800), connect MINISAS port J15 to MINISAS2LVDS card as LVDS0. J16 to MINISAS2LVDS card for LVDS1. The MINISAS2LVDS card need jumper, please refer to the card datasheet. For LVDS2HDMI card(19201080), connect MINISAS port J16 to panel. For MIPI DSI panel(10802340), connect MINISAS port J14 to panel. For MIPI2HDMI card(1920*1080), connect MINISAS port J14 to panel.
Prepare the Demo
Connect 12V power supply and J-Link Debug Probe to the board, switch SW4 to power on the board.
Connect a micro USB cable between the host PC and the J31 USB port on the cpu board.
Open a serial terminal with the following settings:
115200 baud rate
8 data bits
No parity
One stop bit
No flow control
Download the program to the target board.
Launch the debugger in your IDE to begin running the example.
Tips: The APP_DISPLAY_EXTERNAL_CONVERTOR can be set as 1 when you are using MIPI2HDMI card(ADV7535) or LVDS2HDMI card(IT6263) only.
In this function, the default port is LVDS port. If you want to use DPU_DI_MIPI, please change as below in dpu_example.h #define DPU_DI_MIPI 1 #define DPU_DI_LVDS 0 #define LVDS_DUAL_PANEL 0 #define DPU_EXAMPLE_DI DPU_DI_MIPI #define MX8_DSI_OLED2 1 (for MIPI DSI panel) or #define MIPI2HDMI 1 (for ADV7535)
