Detailed Description
This is the main class to get Segger's emwin library up-and-running with the mbed online tools.
This class handles the porting/integration layer in emwin and the virtual methods must be implemented in a sub-class to handle such things as memory allocation, framebuffer association, display size, and touch events.

| virtual uint32_t getDisplayHeight | ( | ) | [pure virtual] |
Returns the height of the display.
| virtual uint32_t getDisplayWidth | ( | ) | [pure virtual] |
Returns the width of the display.
| virtual void* getFrameBufferAddress | ( | ) | [pure virtual] |
Returns the address of the framebuffer (video RAM).
This address will be given to emwin by a call to LCD_SetVRAMAddrEx.
| virtual void* getMemoryBlockAddress | ( | ) | [pure virtual] |
Returns the address to a memory block which may be used by emwin to allocate objects.
The memory block returned will be given to emwin by calling GUI_ALLOC_AssignMemory.
| virtual uint32_t getMemoryBlockSize | ( | ) | [pure virtual] |
Returns the size of the memory block returned by getMemoryBlockAddress().
| virtual void getTouchValues | ( | int32_t * | x, |
| int32_t * | y, | ||
| int32_t * | z | ||
| ) | [pure virtual] |
Get touch coordinates (if the display has a touch panel)
- Parameters:
-
x the x coordinate y the y coordinate $param z the z coordinate. If the value is > 0 the panel is touched.
