I am trying to set my marlin to advance extrude ,
so i add my own constant to marlin like below
#define ADVANCE
#ifdef ADVANCE
#define EXTRUDER_ADVANCE_K .0
#define D_FILAMENT 1.75
#define STEPS_MM_E 39.3716849
#define EXTRUTION_AREA (0.25 * D_FILAMENT * D_FILAMENT * 3.14159)
#define STEPS_PER_CUBIC_MM_E (axis_steps_per_unit[E_AXIS]/ EXTRUTION_AREA)
#endif // ADVANCE
but when i trying to upload it to Arduino,
It come out Error messages like this,
stepper.cpp: In function 'void TIMER0_COMPA_vect()':
stepper.cpp:742:5: error: 'OCR0A' was not declared in this scope
OCR0A = old_OCR0A;
^
stepper.cpp: In function 'void st_init()':
stepper.cpp:995:5: error: 'TIMSK0' was not declared in this scope
TIMSK0 |= (1<<OCIE0A);
^
stepper.cpp:995:19: error: 'OCIE0A' was not declared in this scope
TIMSK0 |= (1<<OCIE0A);
^
The version that i use is bobc's marlin for arduino due
i wonder if there is something wrong when it trans from mega Ver. to due Ver
can anyone helps
thx
