The new firmware also includes a screen calibration feature. You can perform touch calibration by clicking the center area of the screen on the startup page (My Box hasn't been turned on for a long time, and the touch has become unresponsive; this only applies to resistive screens, and capacitive screens do not require calibration).
Regarding the "card startup" interface, I'm still unsure of the cause. However, in my testing, I have never encountered this situation before. Personally, I believe that the most likely causes are either a problem with the NextionDriver driver or an issue with the screen baud rate.
The WPSD system settings are as follows:
Select display type: "Nextion (enhanced with driver, attached to modem)"
Select "modem" on the port.
Nextion Layout selection: "ON7LDS L3"
The PI-STAR system requires separate installation of NextionDriver, with the following settings:
Select "Nextion" for display screen type.
Select port "/dev/ttyNextionDriver"
Nextion Layout selection: "ON7LDS L3"
The default baud rate is 9600. If you still see the startup page, try the following to modify the baud rate:
1. Click the MMDVM icon on the startup page to switch to the main page.
2. Click the MMDVM icon on the main page to switch to the system information page.
3. Click the "Baud Rate" button to switch baud rates. After a successful switch, the current baud rate (9600 or 115200) will be displayed on the screen.
If you are still unable to resolve the issue, please provide the system (PI-STAR, WPSD) and version that you are using. I currently do not have access to a PI-STAR environment, so providing the original serial port data would be helpful in troubleshooting.
