Hello Jasem:
I have written a driver for TeenAstro, with all basic functionality tested. It is in my fork github/fdesvallees/indi. Since I am not familiar with git I am not sure how to proceed now. Note that I have written some documentation according to your recommendations, but I don't know where to submit it. Can you please help? Thanks, François

François Desvallées created a new topic ' Add delay between end of slewing and start capture?' in the forum. 2 months ago

I am starting to use Ekos for astrophotography, with an LX200 compatible mount and Nikon D750 (no guiding yet). The first image after each slew shows bad stars. I guess the mount was still moving while the scheduler started capturing. Subsequent pictures are ok.
How can I add a delay between end of slew and start capture?
Thanks

Thanks Khalid, this explains it.

But I don't understand how we can make Ekos work: eithee we keep the connection open all the time, like a serial port, or for every command issued (and this can be one per second or more when polling the mount), the driver needs to open the connection, issue the command, then close the connection (not nice). What do you think?

I am testing communications through EKOS and a TeenAstro mount controller. TeenAstro does not have a serial port, it communicates through TCP instead.
I used the LX200 Basic driver, because I was not able to configure OnStep for TCP (it seems to connect through serial only).

The communication starts fine, I can read the initial coordinates of the mount,

I started investigating, and found out this is due to tty_write() returning an error: first TTY_WRITE_ERROR then TTY_OVERFLOW.

Before continuing, I would like to ask if anyone recognizes this, and ask for suggestions on how to fix it. Thank you!
