Step 3Viewing JPEGs
All JPEGs begin with 0xff 0xd9 and end with 0xff 0xd8. Use the code provided by LinkSprite to stream data serially and make sure that that the first two bytes are "0xff 0xd9" and the last two bytes are "0xff 0xd8". If you aren't seeing the correct beginning and ending bytes, recheck your connections and maybe add longer delays between reading bytes.
After you have successfully streamed data to the serial terminal copy, paste the data into a text file. Now all you have to do is write the data to a binary file. You can't give your file an extension of .jpeg. My friend Ron wrote a python script, which I have included, that takes advantage of python's "struck" module. This script reads in a text file of hex values and writes to a JPEG file.
The LinkSprite camera has a resolution of 160x120; I've included an example image to give you an idea of the quality/size.
You will, most likely, have some errors in your photo. If you don't, that's great! If you do, please read the next step!
