The PIC C-compiler demo that can be downloaded from http://www.bknd.com actually comes with a version that does optimize. On the other hand it can only generate 256 instructions compared to the 1024 of the less optimizing demo version. A free PIC C-compiler that can generate 1024 instructions is a pretty good deal though!... That's everything you need for a 16F84! Even without the highest level of optimization the code generated isn't worse than from any other available compiler. -AW -----Original Message----- From: Andy Kunz [SMTP:support@MONTANADESIGN.COM] Sent: Tuesday, June 01, 1999 3:08 PM To: PICLIST@MITVMA.MIT.EDU Subject: Re: "New" optimizing PIC C-compiler: >demos! (Limitations of the free demo: Max code size=1024 instructions, only >basic optimization, variables = max 16 bit.) That's a stupid limitation. If somebody wants to buy a compiler, one of the biggest points in the evaluation is optimization. I'm still VERY happy with my HiTech compiler.

CC5X supports both low end (12-bit core 16C5X/12CXX) and midrange (14-bit core 16CXX) PICs. CC5X ver 3.0 that was just released has a lot of new features including 1, 8, 16, 24 and 32 bit variables, signed and unsigned. The price for CC5X is only $120 (reduced), $280 (standard) or $550 (extended)! When I compared it to MPC, MPLAB-C, HiTech, CCS and IAR they all generated at least 25% more code plus usually required several times as much RAM space. CC5X is stable! I have been using CC5X for all my PIC projects since 1992 and during that time I have only found a couple of bugs (which have all been corrected). Check out http://www.bknd.com. Possible to download working demos!
