==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.
