I haven't heard about the HCPIC compiler!!!
But! Hi-Tech lite is free and compiles any size code...However!! optimization is switched off and your code will be bloated... Ie.. 2k of code will come out 2.5k ~ 3k..
Enterprise edition Has a basic optimizer... 2k of code will come out around 2.2k~ 2.5k
Pro Edition Has a full optimizer and will give the tightest code...
The difference in £££.... Lite... Free. Enterprise... @450~500... Pro 650+
You cannot get Hitech any more... You have to use XC8, XC16 etc....
