Onstep telescope control
From Blue-IT.org Wiki
I am using the Onestep telescope control in conjunction with a Raspberry PI and the Astroberry Server and an old refurbished EQ-5 (when times come, I will post a reference for the project here).
Max PCB v1.135
Teensy 3.6 and INDI
After dealing with a lot of trouble getting teensy to connect with EKOS/INDI (see Astroberry Server), I had to do the following things on my astroberry server:
1. Problems with teensy connecting to modem manager:
Uninstall modem manager (it is not needed anyway until you like to use an usb modem):
sudo systemctl stop serial-getty@ttyACM0 sudo systemctl disable serial-getty@ttyACM0
and
apt-get remove --purge modemmanager
2. In any case install the udev rules!:
I use these special rules which ensure, that the teensy always get the same device address: "/dev/onstep":
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", ENV{ID_MM_DEVICE_IGNORE}="1"
ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789A]?", ENV{MTP_NO_PROBE}="1"
SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789ABCD]?", MODE:="0666" SYMLINK+="onstep"
KERNEL=="ttyACM*", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="04[789B]?", MODE:="0666"
So you can use as teensy device in Ekos for the LX200 OnStep:
/dev/onstep
Indi driver
There is an interesting thread about the Indi driver LX200 Onstep in the indilib forum.
