dokeeffe / ip-focuser Goto Github PK

Hi Derek,

Sorry this is not an issue as such, but more of a bunch of questions!

I came across this great project via the Indilib forums when I was searching on DIY focusers. I had been intending to have crack at building a focuser running from an ESP8266 (WiFi) module over IP and there was a lot of parallels with your project here.

I actually have successfully ported your code into an ESP8266 based solution, my motor was also different (it is a cheap as chips motor / driver board => ULN2003APG board and 28BYJ-48 stepper motor) so I had to port to motor control code also.

One or two questions....
Would it be possible to provide a pre-built copy of the indi driver? I have not managed to install the whole toolchain for driver compilation and if it is not too much trouble this would be very handy for testing outside of a terminal / curl.

The Arduino library I found for my stepper motor has a 'setStepDuration' API which is basically a 'setSpeed' method. In my case, the lower the number the 'faster' the stepping => eg. setStepDuration(1) is ten times faster than setStepDuration(10). Do you think this matters in terms of how the firmware communicates with the driver (eg. bigger number is expected to be greater speed) - if it does matter I guess I can somehow translate the speeds to match according to an expected speed range?

Last question! When putting this to use (although I have not figured out how to mount the motor on my C8 yet) would you typically get the focus roughly correct manually before connecting the driver to Ekos?

Kind regards, Féilim

PS I happen to be based in Cork also - in the city :)
