I write all info about in NanoVNA group in my firmware topic
/g/nanovna-users/topic/nanovna_firmvare_compiled_by/73181877For transfer data need eject SD card from slot and put in PC card reader, screenshots stored in standart Windows *.bmp file format vs 16bpp color.
If not use FatFS lib for support Fat32 filesystem, possible save and load data by sectors 512 byte size (can be useful for stand alone use) or use more simple filesystems. If need just read (and write vs some limitations), possible use very compact PetitFS lib, it need just ~2kB flash and very fast
PS Sorry for my typo, not SC, it SD card
