how to Display image on Kentech display in tm4c129x board from SD card

Hello Priya

TivaWare comes along with an application called pnmtoc. This converts a pnm file to hex format. There are web tools to convert bmp/jpg/etc to PNM format.

When it comes to images in the sd_card, note that the sd_card is not executable format. The files need to be brought on SRAM before the same can be sent to a Panel.

There are no ready to use examples for sd_card to LCD Panel.

    iFResult = f_read(&g_sFileObject, g_pcTmpBuf, sizeof(g_pcTmpBuf) - 1,

                              (UINT *)&ui32BytesRead);

    GrImageDraw(&g_pcTmpBuf, g_pui8Image, 0, 0);

Hello Priya,

if the data is a raw format data, then you would need to use the PixelDraw to draw each of the pixels based on the image content
