want to display Images written into SD card on blue screen(Graphical LCD) connected to LPC2378 please help if any one have tried the same one.
Accessing an SD card works the same irrespective of the file content;
Displaying images on a the screen works the same irrespective of where the data came from.
So tackle one first, then the other, then bring them together...
do you any example program to access Image or even any text file from SDCARD for lpc2378. since I am struggling to get things but not able to do.
Thanks
Using SPI, or the "full" SD interface?
any one will be ok
In that case, you should have no difficulty finding something!

Please refer MP3 player sample code provided with bluescreen kit along with Bluescreen_Manual.
For Image Display (From Prog Mem) ----> First convert the into hex file. Then inclue image file as .h in you program. You can use ScrObjInit(MP3ScreenInit) function to display image.
MP3ScreenInit() is another function in which you initialise structure object so_obj. This structure contains functions related to each image.In that structure draw() function is present which actually display image on LCD. Please pass base address of array of image hex file to TSLCDShowPic2() function present in draw() function.
