I didnt guess, with this pinout no problem with fw 8.05-8.11, and also the 33,35 etc pins not not connected to my custom pcb or any other components
Connected pins to only to drivers (nothing else):
#define dirPin_0_Define 30
#define dirPin_1_Define 18
#define enablePin_0_Define 20
#define enablePin_1_Define 8
#define stepPin_0_Define 28
#define stepPin_1_Define 16
#define modePins0_0_Define 26
#define modePins1_0_Define 24
#define modePins2_0_Define 22
#define modePins0_1_Define 10
#define modePins1_1_Define 12
#define modePins2_1_Define 14
Analog (resetPin_0_Define) doenst required for drivers, I mean it works without analog.
Complied with Aruino IDE and Atmel Studio, same issue.
Its a very little and compact pcb, size about 5x8cm, only for motor drivers with mega2560mini. I didnt need any special like st4 and others.
And it fits well into eq6 mount.
Probarly its not hardware problem, this should be work without any pcb.
I compared fw 8.05 and 8.21 and there is no "significant" change in astroeq.c some const, and some functions are "different" etc.
