Ignore anything on the splash page and go to Tools -> Options -> Embedded -> Build Tools tab. This should result in a message indicating a symbolic link named “_c18bin_” was created.
MPLAB XC8 VS C18 PASSWORD
(Using the ‘runas’ command, Windows 7’s answer to sudo, apparently does not work for this as it forces you to know the actual administrator password, and will not accept your user password even if you have administrator privileges.Īt the console, cd into the XC8 directory directly above the binaries directory (e.g. The way I found that works is to create a batchfile with the contents “cmd pause”, then right-click and “Run As Administrator”. To do this, you have to first-first-first somehow get a Windows console with Administrator privileges. If not, you could also try just copypasta-ing the entire contents somewhere else, and hope this doesn’t break a path dependency somewhere or whatever. NB: The below workaround only works if your filesystem is NTFS. So you have to create a fake instance of this directory (symlink or hardlink) with a different name to fool MPLAB X. Unfortunately this is EXACTLY WHAT MICROCHIP’S OWN XC8 COMPILER DOES (of course that directory is already used for XC8 itself, which IS autodetected somehow). The bug is you are arbitrarily forbidden from having two toolchains set up whose executables are in the same directory. But first-first, you need to workaround a stupid MPLAB X bug that has been unfixed going on two years now. The fake “C18” that currently serves as the compatibility layer must first be manually setup in MPLAB X (apparently no autodetect). Make XC8 “C18 Compatibility Mode” findable: Voodoo happens and it should “Just Work”.
MPLAB XC8 VS C18 INSTALL
If you have the license file, ignore absolutely anything to do with licensing and install as if you want the “free” version. NB: Licensing is done via a Windows batchfile, completely outside any of the devtools OR their installers. Install MPLAB X (make tea, a sandwich, possibly a baby or two while waiting for the crunching sounds from your harddrive to finish) and XC8.
MPLAB XC8 VS C18 CODE
Of course, if the code from 5 years ago, even with no changes, still compiled and fit onto the chip it was written for and used to fit on 5 years’ worth of versions ago, and current MCC18 did not insist on dragging in the gargantuan (>4KByte) ‘.code_vfprintf.o’ even if it is not used or referenced anywhere in the code, I wouldn’t even have to bother trying it with the new compiler in the first place…. Insert whining about the month+ long circlejerk with Microchip Support about the bug in the PICKit3 programmer that is now corrupting the config bits on said product here. If I didn’t just need to make “a couple tiny updates” to an already selling, on-the-shelf project I’d just scrap the PIC18 for an EFM32TGxxx part, gcc (shaft of light from the sky, harps playing melodically) and be done with this entire shit-show. I see in the pic and avr compilers that sin(x) in most cases is approximated by Taylor series which is very time consuming.First note to myself: NEVER USE MICROCHIP AGAIN.
MPLAB XC8 VS C18 HOW TO
Sometime ago I see an application note from TI, in which I read how to implement the function sin(x) very effectively for signal proccesing purposes in dsp controllers. Has a very friendly and powerful debbuger Has as many as possible libraries (functions and peripheral chips) Gives the fastest (in execution time) possible code
Gives the smallest (in size) possible code It is easily to say that the good compiler is that who I think the most experienced members here after a discussion, to post a sticky for this: how to test a compiler.
I see from time to time posts in various forums, personal opinions about what compiler is the best. I install xc8 and I see in installation folder known parts from both hitech and mplabc18 compilers. Second I know that these compilers are going to at its end as soon they are substituted with xc ones, so my post concerns the collectors. The first thing is a clean(or official) method to install without fake.exe or other tricks.
