"you need to change the configuration screen" what does it mean?

Your model belongs to t5c2 platform, so CRC verification is not supported at present. You can replace dmg80600c104_ 03W this model of screen, this can be degraded to instruction set after use, can support CRC verification

I get it now. You meant me to change the screen model.
It may take a long time to implement this solution. I want to change my screen model in the future. but for now I need another solution.

What should I do to avoid errors while reading data from the memory of the screen? What do you recommend?

At present, we can see whether the deviation of baud rate between MCU and screen is too large。The 40 ms cycle is the screen. Whether there is an interval for sending instructions,

Unfortunately, what you are saying is not understandable. what exactly did you mean?
