Hello. I use PL2303 connect to Rx2 Tx2 to receive data auto uploading. It works well in just 2 3 minutes, then the data was not come any more. I check the wire, connect but it doesnt have any problem. What happen? Help me please!

Hello, your PL2303 is switched from UBS to TTL level. Your screen defaults to RS232. You can short-circuit a solder joint at the back of the screen to TTL point (red box position), as shown in the following figure:

Is there no communication information on your screen now? You download the attachment and try the factory program.

I mean my screen work well, all design and animation works like I want. But the objects that have "Data auto-uploading" function doesnt work!

First, check whether your CFG configuration has enabled the data upload function. Second, check whether the automatic upload of touch button data is checked when you are working on the project.
