I made a mouse with STM32 project, encounter a problem, now know that the resolution of the computer, also can obtain the relative coordinates to the mouse data, a serial port receives from the absolute coordinates of the mouse data to the control PC, could you tell me, how the absolute coordinates of the data can be converted to relative coordinates, to control the movement of the mouse? For the mouse don't really understand it absolutely, sincerely for advice! A little bit in detail please, thank!
By rights, I need to remember the location of the mouse first, but the initial location as if not sure,

CodePudding user response:

Mouse back to the data is not absolute, relative coordinates, but you need to be accumulated operation can be absolute coordinates

CodePudding user response:

For motion vector, or the need to statistics
