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

2. Precautions for disp resistance welding

• When connecting the wildfire development board for use, the disp resistance must be removed, otherwisethe 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.

3. P2 and P3 interface pins are described as follows:
