It is DMG80480T043_09WTR.I finish design user interface in LCD and download program through SD Card. Then I want to debug and connect to my MCU. I just connect it with PL2303, I reinstall the driver but it didnt work 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: I have done that but it didnt work. 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.
