Focuser
Focuser for Astronomy based on Arduino (usable by INDI)
This focuser is used with INDIlib It use the protcol Moonlite (As documented in the indilib project). This focuer was based off of Hans Astro Focuser , you should look into that one you may like it better. It has more features.
Mainly I just removed the temperature sensor, display and made it work with the Adafruit Motorshield v2(AMSv2). I had a few of the motorshields laying around so thought I would use one. The A4988 controller used in the original repository is a good stepper controller but I had the AMSv2 laying around.
Only 16 microstep speed is currently supported.
Element used
- Arduino Uno (link)
- A bipolar stepper motor
- The Moonlite Protocol
- A AMSv2 Stepper motor controller
- AMSv2 library
Internal library
- Moonlite. Used to code and decode the Moolite protocol
- StepperControl_AMSv2. Used to command the stepper motor
Compilation
The files are location in the Arduino/Focuser folder. You do need to install the AMSv2 library for it to compile. The Arduino IDE is recommanded for an easy compilation. To compile you need to open up Arduino/Focuser/Focuser.ino. The Arduino IDE can be found hier: link
Compile and transfer the program to the Arduino.
When you start your Indi server use the indi_moonlite_focus module to enable the focuser. The software provided by Moonlite on Windows is also usable.
