Storing texts in external flash in TouchGFX 4.25

[Matthew140801]

Hi,

I've recently migrated to TouchGFX v4.25. The changelog seems to indicate that we can now store our texts in an unmapped external flash, for example an SPI flash. When going through the following page of the documentation :
https://support.touchgfx.com/docs/development/scenarios/fonts-in-unmapped-flash , it only mentions fonts and not the actual texts. Does the same principle apply to texts as well, or is it not possible to store texts in an unmapped SPI external flash ? Or am i not looking at the right documentation ?

Best regards,

Hello @Matthew140801,
Yes you can, if they are converted as binary, then you can retrieve them by loading the data with the address where they are .

Thanks for the reply. If i use this approach, would the buffers used to read the data need to be large enough to contain the whole binary files ?In that case, it would imply having 12 KB and 14 KB buffers allocated in RAM, which would not be a convenient approach in my case.

The buffer should have the size of your data but you could also try to directly pass the address instead of loading it to the RAM.
