Hello

   I'm using emWin.

   It is a straigthforward work to draw a bitmap picture using bitmapconvertor for emWin.
   There is an explanation for "Displaying Bitmap Files" in the chapter-8 at emWin User Manuel. However it is not so clear.

   Is there a code example for drawing a bitmap picture from SD card or any other storage media ?

If the image data is not available as a const array in a memory mapped area, emWin also supports loading of image data from streaming devices like an SD card or SPI, or UART or whatever.
As Wouter already mentioned, you need to adapt the GetData function according to your enviroment. Look into the emWin docu in chapter "Displaying bitmap files / Getting data with the ...Ex() functions", there is a meaningful example.

An example for an SD card file system for LPC1800/4300 can be found in in the LPCopen software package in .\lpcopen_v1.03\applications\lpc18xx_43xx\examples\periph\periph_sdmmc.
For other MCUs there are similar examples, either from us or 3rd parties or from the community. Just Google for it.

Hi,

You'll need to use the GUI_BMP_DrawEx() function for that.
Segger has an example of using this function in their "Drawing bitmap files" tutorial on http://www.segger.com/emwin-samples.html
You'll need to adapt the _GetData() function so that it reads the data from your storage device.

Regards,
Wouter
