Error Compiling
Posted: Fri Jul 06, 2018 3:28 pm
Hi,
So I managed to get the simple-wifi example working fine. However, my own main C code isn't compiling and I can't figure out why.
I understand that I don't have error checking in this. It's just a very simple version to get me going on how this stuff works. The errors are as follows
I'm using Ubuntu and no IDE - just Atom text editor and terminal. I used make clean and make flash to build it.
