How to download pictures to 2440 under Linux

shandong
What is the method to be used to transfer a JPEG or BMP image from the
Linux host computer into the mini2440 to display it on the screen? Is there
a way of doing this in C?

I transfer files via FTP on the LAN cable.  Qt is the program to create gui
apps.  So there are two ways to do this:

1. Create server/host apps using QSocket and send the pic directly to the
app on the mini2440.

2. Simply copy a file to a directory on the arm9.  The file would always
have the same name, or alternate between two names if you get a conflict
with a file being in use.  Then set up a timer in you arm9 app to reload
the file on a given time basis.

3. Simply transfer all the pics via FTP with names like pic001, pic002,
etc. and have your mini2440 app read them in sequence.

I have not done this personally, so I can't guarantee this will work, but
hopefully it will get you started.

By the way, acceptable file formats are bmp and png, but I do not think you
can load a jpeg into a Qt application.
