thanks xiang,

i referred the files you included, can i do it without using app wizard and gui interface? 

and if possible do tell a reference to make the image display in the main screen of the board instead of  the cursor, it has only told for the cursor display of the image not for the whole screen.

please do help me as soon as possible.

with regards

Hi, Suraj,

After you unzip the an12027 package, you can see the directory, for example lcdc_1_tft16bpp example. It fill the LCD memory buffer with constant data.

But I think it is difficult to convert a portrait file to pixel data, because you have to parse the file format, extract the pixel data and fill LCD memory buff.

Hi, Suraj,

From your description, you want to display an image, which is a static portrait, I think it is okay, you need to declare an array, just fill the array with the portrait pixel, it is okay.

This is an application note for the LCD, I think it is helpful.

hope it can help you.
