Touch Screen Example, Help!!! #26

Closed okooo5km closed 4 years ago

okooo5km commented 5 years ago

Based on your work, I have developed the Touch Screen class after reading the document (DigitizerDrvs_touch),but it does not work well! Windows 10 can recognize it as the HID device not a pen or a touch panel. I think maybe it needs to send the feature data to win os. Now I have no idea about responsing the GET_REPORT or SET_REPORT request, Could you give me some suggestions?

Sorry, I don't know how the touch panel profile works.
