Interface Definition

①--Capacitive touch screen circuit
②--Resistance touch screen circuit
③--Disp resistance
④--P2 interface (compatible with atomic RGB interface)
⑤--P3 interface (compatible with wildfire RGB interface)
⑥--Module ID defines resistance (only for atomic program)

1. Switch touch screen

If you choose to connect the capacitive touch screen, please weld the capacitor touch screen circuit;
Select the connection resistance touch screen, please weld the resistance touch screen circuit;
If you often need to switch the touch screen, after welding other circuits, only switch the drain
resistance in the dotted line box;

2. Precautions for disp resistance welding

When connecting the wildfire development board for use, the disp resistance must be removed, otherwise
the screen will not display after the development board is reset;
When connected to wildfire i When using the MX6ULL ARM Linux development board, you need to remove
the DISP resistor and the three resistors in parallel, otherwise the development board will not run.
When connecting atomic development board, f407 minimum system board or esp32 development board, disp
resistance must be welded, otherwise the screen will not be displayed.
