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.

SOLVED by Yang - I have NOT been able to do multi threading, but I guess saving images in their own thread would be more effective?

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
./make.sh					                        # compile capture.cpp to startCapture
reboot NOW !!!
./asiSnap					                   # run compiled program for about 5 seconds and do CTRL+C
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 ./startCapture program again with all the switches you like or need.

This is what I need help with if someone can:

SOLVED by Yang - Make a new thread that saves images while new images are created

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 ;-)

Hi, I have fixed the bug in your code, you have to call ASIInitCamera after opening camera, and saving images is moved to another thread, I build it on x86 Ubuntu.please test it.

Hello Yang and thank you very much!

I see you have done a lot of work but I still get the ASIInitCamera error.

It is the same error as I got, so I removed it in my previous code because I could not find any error.

Here is the error I get when compiling and maybe there is an error in the compiling line?:

Error - ASIInitCamera.png

That's because there isn't ASIInitCamera in the linked libASICamera2.so, use nm -D libASICamera2.so|grep -i ASIInitCamera to check this, SDK of version 0.4.xxx have this API.

I have the file: libASICamera2.so version 0.4.0929

I got nothing when i ran this: nm -D libASICamera2.so | grep -i ASIInitCamera

I get this whenI run: nm -D libASICamera2.so
