Hi, Joel, thank you for the answer! 
	I set CPU and compiler as shown below:
 
	#define GFX_COMPILER                             GFX_COMPILER_KEIL
 
	#define GFX_CPU                                  GFX_CPU_CORTEX_M4
 
	Unfortunately, I forgot to set heap size (my bad), but when I've set it to #define GFX_OS_HEAP_SIZE  37632   after your answer, nothing changed. The larger values leads to many errors during compiling. 
	Is there something else that could be a problem?
