TOPIC: Moonlite focuser protocol

Moonlite focuser protocol 4 weeks 12 hours ago #29000

I had the same problem. I have the Arduino version working well on a Nano using the Indi Ekos system. I have also tested it using the serial monitor of the Arduino IDE. All works fine.
However it will not work with the Moonlite standalone app. In fact it will not even recognise the device. I know for the Arduino Nano has had issues with switching drivers over the years and I can only assume that the official app has a built in driver and expects a specific board. The original author of the software I used said it worked using an Arduino UNO. I have not tested it, I am happy that Indi works with my focuser and does what I need.

Hello, Max.
I hope you had a good holiday. I was wondering, as we talked about a few weeks ago, if you'd be so kind as to upload the schematic of the electronic connections of your version of Hansastro's montage. It seems that you have changed the pin of some connection and removed one of the resistors... Let's see if I can get the LM335 sensor working properly...
Thank you in advance

I will see what I can do to draw up some sort of diagram. However most of the connections are the same as the original schematic.
the only physical changes I made were:
-Changed temp sensor to pin A0, in the original code it was pin 3,
-left off the potetiometer completely , adjustments made in software
-connected a I2C display to : A4 (SDA) and A5 (SCL) which is used in the original code but not shown in the schematic

Attached is my schematic of the Arduino MoonLite Focuser Schematic derived from Hansastro Focuser. See explanations earlier in the thread. My code at github.com/mdobres/MaxFocuser is a slight variation of the original Hanastro Focuser at github.com/Hansastro/Focuser . The Arduino code also contains a list of Pin Assignments.
My version no longer has a Pot to calibrate the temperature, I do it in the Arduino code using a constant as follows:
tempcorrect= 178;

You change that number adjust the temperature just once when you set it up.

Thank you very much for the work you have taken to make the diagram. It has been a great detail.
Just one more question. On what basis did you enter the number 178 as "tempcorrect"?
Thank you in advance.

I had the real temp from an accurate source and just varied the number by trial and error. Its a simple addition/subtraction
