Issue with Linksprite and Linux


Today, I want to create this article because I have been looking for a solution in 3 months.
The problem was with the magic Linksprite Camera JPEG, that you can buy on Sparkfun. This camera is a good solution to  have implement a camera on your project.
I was working on my project and I couldn't finish it because I found a problem with the communication between my Arduino and the Camera.


Basically every time that your turn on the camera you should receiver an INIT STRING:

VC0703 1.00
Ctrl infr exist
User-defined sensor
625
Init end

and in HEX codes is:
56 43 30 37 30 33 20 31 2E 30 30 0D 0A 43 74 72 6C 20 69 6E 66 72 20 65 78 69 73 74 0D 0A 55 73 65 72 2D 64 65 66 69 6E 65 64 20 73 65 6E 73 6F 72 0D 0A 36 32 35 0D 0A 49 6E 69 74 20 65 6E 64 0D 0A 

I was checking to get the same init when I was turning on the camera but I was getting something strange:
096A198136999B2C1C11514DE1E4AC90B457595CA82CAFD5175788AC6AD5E45AA4B2B32D6B455DAD5DCE6AFB98D859B498D21E189B7B45A48294BD5A4FC

How you see the result on Linux isn't right, is totally wrong!

I was looking for a solution on the internet, forum, etc... I found one post where a person was talking about the issue to compile the same code on difference OS, in particular that on Windows works and on Linux doesn't.


In the end I tried to use the same Arduino IDE on Linux and Windows and then I compared the result:


Windows:
056433037303320312E3030DA4374726C20696E6672206578697374DA557365722D646566696E65642073656E736F72DA363235DA496E697420656E64DA

Linux:
096A198136999B2C1C11514DE1E4AC90B457595CA82CAFD5175788AC6AD5E45AA4B2B32D6B455DAD5DCE6AFB98D859B498D21E189B7B45A48294BD5A4FC

Evidently there is something wrong on the Linux's compiler.
So, my solution now is to move the project on Windows and finally complete it.

I hope this article will help someone that has got the same problem.

There is no code, you can get the example from Linksprite's website
