How do I upgrade XC8 compiler from free version to Pro with Omniscient Code Generation? I have installed XC8 under MPLAB-X and I have rapidly filled up the device. When I installed it, it said that I could upgrade to Pro mode for 60 days. Memory Summary: Program space used 36D4h ( 14036) of 4000h words ( 85.7%) Data space used 172h ( 370) of 400h bytes ( 36.1%) EEPROM space used 5Ch ( 92) of 100h bytes ( 35.9%) Data stack space used 0h ( 0) of 19Ch bytes ( 0.0%) Configuration bits used 2h ( 2) of 2h words (100.0%) ID Location space used 0h ( 0) of 4h bytes ( 0.0%) Running this compiler in PRO mode, with Omniscient Code Generation enabled, produces code which is typically 40% smaller than in Free mode. The MPLAB XC8 PRO compiler output for this code could be 4800 words smaller. See for more information. I have looked at Forums and noted the 'Options for XC8' and it is set to Pro.
I get the output above on 'Clean and Build'. Drivers Of Globalization Technology And Innovation. I get an identical output under 'Free' mode with 'Clean and Build', so the Pro switch is having no effect. I installed this before the Masters 2014 and I was pretty sure I did the 'Free' install, but it occurs to me that the Pro mode has expired. Would this be a fair summary?
