Where can I find the source for this. Arduino and the driver. I have some interest in doing something similar and would like to see what the code looks like. More than fairly certain I can cope at the Arduino end but hate C++ and will probably have even stronger feelings about any use of xml.
I'm currently working on an alternative arduino + stepper based focuser.
It provides an HTTP json interface and an indi driver (which uses this interface).
Other features are backlash compensation and an "always approach CCW" setting for use with SCT telescope mirror shift focusers.
Its still work in progress but seems to work well. Currently Its working but I need to do more field testing which is weather dependant and causing serious delays (Irish weather is very bad!!)
Once I get it up and running smoothly I'll update the project documentation.
