Question

Is it possible to use LIBJPEG for STM32L496?

In the designer I selected STM32L496G-DISCO. But no success.

I know it will only support software decoding, but still I will try it for my application. (small display and low fps).

Software based yes, but if you mean cubeMX selection , this is only for hardware F7/H7 equiped jpeg codec.

The software decoding solution requires that the LibJPEG middleware is enabled from CubeMX, as specified in TouchGFX Generator User Guide. Software decoding setup is identical for all LibJPEG capable MCUs (e.g. STM32F4, STM32F7, STM32H7).

What to do when using STM32L4?

Can you guide me more to use the software based LIBJPEG?

Do I need to update anything from CubeMX?

The make-files in TGFX Designer will not support video. Will I need to change them? How?

Can you show me an example?

My display is 170x320 pixels and I need 15 fps. Will that be possible with SW based decoding?

Thanks in advance
