Configuration

The I/O Pins are defined in pins_RAMPS.h
At this moment only the following pins are in use:

#define RA_STEP_PIN         54
#define RA_DIR_PIN          55
#define RA_ENABLE_PIN       38

#define DEC_STEP_PIN        60
#define DEC_DIR_PIN         61
#define DEC_ENABLE_PIN      56

#define PS_ON_PIN           12

If you want to controll the power supply via the RAMPS board the set the PS_ON_PIN.

The configuration for the drive logic is in Configuration.h

• Serialport speed is set to 115200. LX200 standard is 9600 Baude.
• Stepper settings. Invert enable and direction signals

The settings for each axis (RA/Dec)

• STEPS_PER_UNIT is in Steps/Deg
  SPU = (Gear Ratio * Stepper Steps * Micro Stepping)/360
• MAX_SPEED is in Deg/Sec
• MAX_ACCELLERATION and DEF_ACCEL is in Deg/Sec^2
• MIN_POS and MAX_POS are in Deg.
• Define if PSU is controlled by AstroDrive
