Note: Because I recently used a PDA to implement camera functions, while my Development Board, mini2440, has only one USB, and my camera is USB, And the mouse is useless. I can only use a touch pen, the Touch coordinates are very inaccurate. First, I thought of tslib used in QT. I looked for it online and found the MiniGUI + tslib
, Atmel provides an 8-byte user data. In this way, the driver can write some signs in it, thus improving the adaptive capability of the driver. It depends on whether the driver designer can think of how to use it and how to use it!
When you adjust the touch screen, it is best to enable the device to automatically run the relevant touch
