Posted on July 06, 2014 at 08:57Hi,
All the sample projects (involving STemWin library) provided by ST do not use the ''
GUI_TOUCH_Exec()'' to update the pointer position, only ''
GUI_TOUCH_StoreStateEx()'' is used instead.
However, as mentioned in the emWin manual, ''
GUI_TOUCH_Exec()'' must be called consistently (every 10ms) for measuring the touch screen and updating the pointer position (through implementing
GUI_TOUCH_X_MeasureX() + GUI_TOUCH_X_MeasureY()).
I understand that ST's project has made the measurement separately in
BSP_Pointer_Update() but my question is, why the
GUI_TOUCH_Exec() is not being used at all? Is it safe to code this way?
Thank you.
