I want to display jpg from SD Card.

I  create a list file from sd card, but I have no idea for next step

Can anybody tell me the next step?

I'm an absolutely(sic) beginner

 

then start with something simpler e.g. 'blinky'

Take a look at the STemWin library and how it paints the JPEG to the screen, or find an equivalent library to decode JPEG images.

May I gently record vote # 2 for Erik's advice - and start w/something far more suited to a beginner.  Suspect that a beginner would be challenged even in ''finding'' STemWin - knowing what to do with it - even harder...

No explanation for this project's need - or goals was provided.  We suspect - that while the internet opens so many interesting doors - the proper mating of ''required skills, tools, appropriate knowledge'' to ''planned task'' - remains firmly closed/bolted...

There exists a faster, far easier means to, ''display pictures'' - while gaining MCU experience.  Digital photo-frames have plunged in price - and w/in the past several years ''Circuit Cellar'' magazine (one example) has outlined a clever means to exploit image display when combined & managed via a far simpler, MCU control board. 

In this manner - many/most of the especially unpleasant & difficult aspects of such a project have been solved - freeing you to focus upon your application and its (now) far simpler satisfaction.
