XC-Compiler: Free- or Pro Version

[tiny]

The XC compiler runs in Free mode. If I buy the Pro version, there is really a more compact code and thus a saving of program memory?
And how is this compiler to enable in FC7?

Hello Christina,

You can run the XC8 compiler in Pro mode for 60 days for free so you can see for yourself how good a fit the pro mode is vs the vanilla free mode.

To switch between compilers just create a new save option in the compiler options window available from the build menu. Then just change the path to the compiler to the path of your XC8 installation.

In most cases the Pro compiler is not required.

Thank you for your reference to the evaluation license.

I built a 4-channel time switch with keys, SMS and WLAN controller and have used a PIC18F26K22.
For this I had Nettime and Email via GSM, but this was simply no space in the program memory!

Here the two results when compiling without Nettime and Email:

with the free version

I think I'm going to buy the Pro version, there is so very saved at program memory!

Thanks again for the tip!
