Hello there

NB. This project are without GUI, no X-Server and suited for light-weighted and embedded systems when finished!

It was created as a All-Sky Camera Command Line Tool for Raspberry Pi 2 and 3

I have now trimmed down the SDK code from Sam's allsky.cpp and Thomas Jacquin's allsky.cpp to work with Minibian and Raspbian lite.

When everything is installed it uses 976MB on MicroSD, 34MB RAM on boot and 160MB RAM when running.

Full Working Setup from clean image with minibian https://minibianpi.wordpress.com/download/

IMPORTANT! Remember there is no sudo installed on minibian image so you are running as root

Default username root and password raspberry

apt-get install -y raspi-config nano # I NOW use raspi-config to expand microsd and reboot

apt-get update # Update RPi

apt-get install -y libopencv-dev fbi # Install OpenCV and fbi image viewer

tar -xvf asiSnap_vX.X.tar # Extract all files to YOUR directory

cp libASICamera2.so /usr/local/lib # Copy this file to avoid error when compiling

ldconfig -v # Load config

./asiSnap

fbi -T 2 image.jpg # If connected by SSH with HDMI screen connected to RPi

fbi image.jpg # Run this if directly connected to RPi with HDMI screen

PS. When you have modified the capture.cpp code, just run ./make.sh to compile your code again and run ./asiSnap program again with all the switches you like or need.

My short but true story!

I started learning C/C++ saturday 15.october.2016 when i found the article of Thomas Jacquin's Allsky camera on the web ;-)

Dear,

Can i change the location of the folder where the images will be stored? For instance on a USB stick...

End, i don't images. It detects the camera and all, but i get an error: Segmentation fault

see file.

What to do?

So 60 second exposure would demand also 60s -d switch...

But that way i would lose a lot of time in between, and some possible bright meteors....

I will first try to get an image from the camera on the SD Card...

Oh okey. I have the raspberry pi initially setup for a SQM meter base station.

The SQM meter program runs in the back and continuesly. Even when rebooting.

But what abouth the image program? I just want to use it to make single all sky shots of 60 seconds.

And to store it, but with time insert. I want to have every minut image. Do you understand?

And so i want it to be running also in the back...

Need to make a code for that i think... :)

PS: what is the exposure time : ns from nanoseconds or ms for microseconds?

i think it is microseconds, right? Then it is ms , not ns like in the yellow text at : exposures.

So if i understand it right, i just run the code:

./asiSnap -t 1 -dly 60000 -exp 3000000 -gain 200 -txt "This is the date: $DATE" -i 4 -f _images.jpg

and then i get the image attached. And then i just need to wait to i see the image line apear?

Great that you learned programming. I want to learn it to!

That is all most correct.

The vriable $DATE cannot be run like this directly from the command line and I have not figured out how to do realtime update of the text so this will be the same when set.

I think you must leave out the txt switch and only capture the image for now

This will take a picture with 3sec. exposure and do this every 60sec.

./asiSnap -t 1 -dly 60000 -exp 3000000 -gain 200 -i 4 -f _images.jpg

the -i switch works like this

-i 1 = 1_images.jpg 2_images.jpg 3_images.jpg to 9_images.jpg and loops

-i 2 = 01_images.jpg 02_images.jpg 03_images.jpg to 99_images.jpg amd loops

-i 3 = 001_images.jpg 002_images.jpg 003_images.jpg to 999_images.jpg amd loops

if the image is to bright you turn down the gain or exposure

Dear,

Seems to me that i'm having some troubles with the program unfortunatly.

Does you work your program as root or as pi?, i can go from pi to root with: "sudo su"

But it seems to me that there are some errors:

In root: i have copied your line: ./asiSnap -t 1 -dly 60000 -exp 3000000 -gain 200 -i 4 -f _images.jpg

And the program starts up: and then the attached happens.

It hangs itself... I don't now why. Even the cancel function will not work ( ctrl + C )

Yes I am running as root and minibian

you must use sudo before every command if you use raspian lite

Remember this is only tested on minibian and raspian lite because it has no X-server.

Okey,

i managed to make "images" with the ZWO ASI camera, but for some reason i don't get any real image.

I get an image file , JPG or PNG as asked, and it's full size of size asked, but it is completely black, and very low kb. only 19kb or so. So someting must be wrong. Drive?

Please post you command line so I know how to retest your settings with mine.

this line I use today

PS if you are not running minibian and are running raspian lite you must use sudo or sudo su befor running the command line

./asiSnap -t 1 -z 3 -exp 2500000 -gain 200 -dly 2500 -i 5 -f _image.jpg

observatory gromme

Dear,

To start from 0, and to run the same command line as yours:

I have a raspberry pi 3 with Raspbian without GUI. So only the command line.

I connect to the raspberry using SSH over local network.

These are my actions when logged in to pi:

1: sudo su ( to go to root )

2: cd ALLSKY ( i go to the folder where asiSnap is located )

3: sudo ldconfig -v

4: sudo ./asiSnap -t 1 -z 3 -exp 2500000 -gain 200 -dly 2500 -i 5 -f _image.jpg ( Your line to test )

Then i get the program attached.

But than it hangs itself. I can let it run for ages, nothing will happen. I cannot exit or ctrl-C the command. I do can right things below ASI_IMG_RGB24 but nothing responds to my commands.

I know that you are not running minibian, so I guess you are running raspian Light. this is not tested with any other distributions.

What are you running?
