Interface Definition

①--DITHB selection circuit

②--U/D selection circuit

③--L/R selection circuit

④--Screen resolution selection circuit

⑤--P2 interface (compatible with atomic RGB interface)

⑥--P3 interface (compatible with wildfire RGB interface)

⑦--B7 Data line pull resistance (required to define module ID, applicable to atomic program)

1. Screen internal Dithering display function settings

Weld the 0 position resistance of DITHB and disconnect the 1 position resistance to enable the internal Dithering display function of the display panel;

Weld the 1 position resistance of DITHB, disconnect the 0 position resistance, and turn off the internal Dithering display function of the screen;

Default welding 0 position resistance, disconnect 1 position resistance

2. Screen display up and down flip settings

Weld the resistance at position 0 of U / D, disconnect the resistance at position 1, and the screen will turn down;

Weld the resistance at position 1 of U / D, disconnect the resistance at position 0, and the screen will turn upward;

Default welding 0 position resistance, disconnect 1 position resistance

3. Screen display left and right flip settings

weld the resistance at position 0 of L / R, disconnect the resistance at position 1, and the screen will turn to the left;

Weld the resistance at position 1 of L / R, disconnect the resistance at position 0, and the screen will turn right;

Default welding 1 position resistance, disconnect 0 position resistance

4. Screen resolution selection

As shown in the screen resolution selection circuit, the module supports screen switching of 800x480 and 1024x600 resolutions.

Weld M0 resistance to GND, M1 resistance to VCC, select 1024x600 resolution;

Weld M0 resistance to VCC, M1 resistance to GND, and select 800x480 resolution;

5. Precautions for connecting to wildfire development board

If connected to wildfire i When using the MX6ULL ARM Linux development board, it is necessary to remove the pull resistance

on the B7 data line referred to by label 7 and the M0 and M1 resistance referred to by label 4, otherwise the development board will not run
