* when writing device drivers not to disturb the assumptions this creates by performing

|
* call-backs to uGFX code unless you define the INTERRUPTS_OFF() and INTERRUPTS_ON() macros.
|
|
* It still requires some C runtime library support...
|
|
* enough startup to initialise the stack, interrupts, static data etc and call main().
|
|
* setjmp() and longjmp() - for threading
|
|
* memcpy() - for heap and threading
|
|
* malloc(), realloc and free() - if GFX_OS_HEAP_SIZE == 0
|
|
*
|
|
* You must also define the following routines in your own code so that timing functions will work...

* systemticks_t gfxSystemTicks(void);
