Can't use C libraries to read images or excel files in Cyclone V project

Hi,

I am unfamiliar with the library itself, could you check out the documentation:

https://github.com/nothings/stb/blob/master/stb_image.h

Regarding the excel, we do not have any examples related that could help, I suggests you try checking and searching in ARM Community support https://community.arm.com/support-forums/ & https://stackoverflow.com/questions/
