Hello!

I am working with an LPC1769 development board and working with the free version of LPCXpresso. I am writing code that is being used for data collection and I am getting a hard fault error when I try to assign the needed number of variables for this project. The code is well within the size allowable for the compiler (120 kb of the 256 kb allowable), but if I try to initialize the number of variables I need, I get the hard fault error, which I already know is an error related to trying to assign memory to an address that is not addressable. Is this an error that can be solved while still using the free version of Xpresso or will upgrading allow me to assign to more memory?

From your description this has nothing to do with free vs paid. You would get linker errors if you exceeded the size limit.

Post your project so we can see what you are doing and suggest what you're doing wrong

When I remove the section for year address at the end, the code works fine and the hard fault does not show up. If I reduce the amount of year addresses to between 1-50, it works, but when it goes above 100 year address, I get the hard fault shown below.

Hard Fault error message from debug:

If there is anything else I can post, just ask.
