an astroguider is a device that monitor a star position using a video camera and send corrective instruction to the telescope mount using a rs232 or a ST4 command

i started from this thread http://www.cloudynights.com/topi ... utoguidingdslrgoto/
the thread is very long, i didn't tried everything so i will describe what i succeed to do for now

my hardware: orange pi pc, a microsoft HD-3000 livecam
an aten usb to rs232 adapter

Orange pi pc setup:
i followed this (step 2) using the LUBUNTU image
http://www.orangepi.org/quicksta ... b482004d81ddbe.html

for setting resolution i followed this http://www.orangepi.org/orangepi ... =viewthread&tid=342 (use uImage_OPI-2 for the OPI PC)

for lin_guider

sudo apt-get update
sudo apt-get upgrade

download and untar from http://sourceforge.n...ects/linguider/

sudo apt-get install libusb-1.0-0-dev
sudo apt-get install libqt4-dev
sudo apt-get install libftdi-dev
sudo apt-get install fxload

build usingcd /home/pi/lin_guider/lin_guider_pack/lin_guider
./build.sh

because of many tries i don't remember if i needed additional libraries, but if there is some missing libraries use (i.e if there is an error concerning missing lib gcc)
apt-get search WHATYOUSEARCHHERE | grep -dev
# -dev because you generally need the xxx-dev library
you should be able to have lin_guider build ok and to launch using
cd /home/pi/lin_guider/lin_guider_pack/lin_guider
./lin_guider

at this point the webcam HD-3000 livecam wasn't detected in lin_guider, solution is to:
-> upgrade to latest drivers:
get the update_kernel.sh from https://mega.nz/#F!wh8l2BjK!OBep3nMldBletvNNwkH2Jg or
https://drive.google.com/folderv ... SEU&usp=sharing

chmod +x update_kernel.sh
su root
./update_kernel.sh

then after the kernel update and rebooting the orange pi
the webcam was working in lin_guider (you need to select it in the video options)

the next step is to make work the aten usb to rs232 adapter
but my understanding is that is should be supported (without any driver installation)
i will update the thread when i will have try it
