Basically I'm reading names from SD card and defining a structure named from the selected SD value. I've got it reading names & values, but I've hit a wall. I have already defined:
Struct Crop { char CROPNAME; byte value1; ETC}
Say per instance I select "broccoli" from the SD file. I want the program to create and name the structure:
Crop broccoli { "broccoli, etc, etc}
from the string that contains the "broccoli" I selected from the SD file. How do I name it from my string or char array?
Forgive the partial code, I've only got internet on my mobile at the moment.
I don't think a processor running a program can add to its own code. Even if you stored in your SD file the machine instructions required, you have no idea where those instructions would need to be placed in program memory, since the compiler allocates locations when it compiles the code. If you pull this off, it will be the hack of the century.
In other words, because the compiler arranges the memory allocation, this is a catch 22. My concern is that with the large structures, if it starts adding cauliflower and a bunch of other crops to the mix, it's going to be an unknown mix number of crops requiring reservations within structs. Back to the drawing board.
you should realize that putting the names in the structure, and the the structures in a list so that you can search through them, is essentially what would happen even in a a hypothetical langauge that did permit you to create structures named via a string...
