Free Search Engine for Mediafire. Aug 19, 2018 - Download MPLAB XC8 C Compiler for free. The MPLAB XC8 C Compiler is a free-standing ISO C90 compiler that supports all 8-bit PIC MCUs.
Maybe is something with me today, but I could not understand completely what he wanted. As far as I understand a software reset does not clear RAM in a hardware way (MCLR reset count as a pin-based software reset also). Indeed XC compiler inserts some code to zero all RAM variables before calling main function. This can be overridden by using the persistent attribute.
Page 63 in XC8 compiler manual, found here: says that, and I quote: '3.5.12 How Can I Stop Variables Being Cleared at Startup? Use the persistent qualifier (see Section 5.4.8.1 “Persistent Type Qualifier”), which will place the variables in a different psect that is not cleared by the runtime startup code.' As for the registers, some will be hardware reset and that cannot be changed (maybe if you write the registers in EEPROM each time you change the registers and then if a reset is detected, some start-up code will restore them) and some will be not. « Last Edit: June 17, 2016, 09:57:13 09:57 by mars01 » Logged. Hi mars01 and metal, thank you for your help. As mars01 noted, a good ide ais use the persistent qualifier.
ASAP I will check this behaviour in the compiler work. I am not too instructed in this compiler, because normally I am using Renesas and some ARM devices under IAR compilers and Atmel Studio. Metal has catch the exact sense of my question. After the reset, some compilers, XC8 too, call some 'lowlevel' function to initialize the processor internal registers, memory, peripherals, etc.
In IAR compiler, normally has a lowlevelinit.c or similar function to do this. In the XC8, you can see in the. Xc8 v1.36 dat some.dat files with informations about the processor configuration and in the.
Xc8 v1.36 sources pic powerup.as This file, you can get a copy and insert in your project to do an initializAtion of the processor before the compiler call to main function. The bad new: this file are assembler, and if we are working in 'C', is a troouble. A better explanation of my question: Assumed we have 1K of RAM memory, after the reset and before main is called, the compiler place some code to clear ALL ram, and I need a block without any changes. Thing, if I am working and an unexpected RESET, is done ( watch-dog, EMI noise, etc), I need some variables not be touched, to remember some states of the machine. Of course, if the reset is done by an power up, or from a switch off/on, these variables, will be set to zero by code.
( I maintain some 'keys' or block CRC to check the health of variables). I have asked tro Microchip support, expect some answer soor.
Thanks again! And sorry for my english! Posted on: June 18, 2016, 08:13:20 20:13 - Automerged Hi again mars01, I have found and read the paragraph you mentioned in the XC8 manual, and OOOPS!
Is the good answer. Thanks a lot. With XC8 v1.40, i can't get the medecine working. If i rename or delete original xclm.exe and then replace it by the medecine, compiler stays in FREE mode. I tried to manually run the new xclm.exe from CMD console window as administrator, but still no chance.
Did i miss something? It did happen to me once and since then what I do is: 1. Move the original xclm.exe from the install folder somewhere else, like desktop. Rename the original xclm.exe to xclm.old 3. Copy the cracked xclm.exe near the xclm.old file, e.g on desktop. Move both files at the same time to the XC8 install folder, where the original xclm.exe file use to be before step 1. Run xclm.exe as administrator I don't know if this method is the only one that works, but it works for me.
In your case, before doing what I have wrote above, you need to uninstall the XC8 compiler, delete the XC8 folder and then reinstall the XC8 compiler. I say this, because once you see that the files can't be patched, my method will not work until you actually do the uninstall - reinstall thing. Compiler Device Version Optimization Program Code size (bytes) XC32 PIC32MX230F256D V1.42 0 9508 2 9464 S 9448 XC16 PIC24F16KM202 V1.30 0 2902 2 2912 S 2900 XC8 PIC18F25K50 V1.38 Free 1544 STD 948 PRO 838 This is probably not the best test program given that sprint probably makes up most of the compiled code, but it does show that the various optimization levels actually do make a difference so all three compilers are actually optimizing. Also I only tested with one device for each compiler. I can imagine that the optimization could be a lot different with different devices. The program may be too small to optimize properly. XC16 actually produced larger code in Mode 2, and Mode S was only very slightly better than no optimizations.
The purpose of the code was to prove that the optimizations were doing something, and they obviously are. The non-Free optimization with XC8 was the most dramatic. The thing I have not proven is whether the optimizations will still work in a month. I'm not sure how to tell if the compilers really think they are properly licensed.
With XC8 v1.40, i can't get the medecine working. If i rename or delete original xclm.exe and then replace it by the medecine, compiler stays in FREE mode. I've been having the same problem. I've got all versions up to 1.34 running in Pro Mode (MPLABX 3.51) but can't get 1.38 or 1.40 to go Pro. Tried all the recommendations in the posts above and more.no luck. I can live with using 1.34 Pro and 1.40 Free, but I'm challenged to figure out why I can't get the later versions to work.
I see there's another xclm.exe inside the MPLABX bin folder.wonder if that has anything to do with it.anybody have further ideas? @chicowood I attach bellow the xclm files (xclm.old and xclm.exe) taken from my own 1.40 XC8 installation folder. Try to uninstall the XC8 compiler, clean the folder if something still remain inside (maybe use CCleaner to clean the registry), install again the XC8 compiler v 1.40, then delete the original xclm.exe from the bin folder in the XC8 installation directory and lastly, copy the attached files into the bin folder in the XC8 installation directory. Make sure UAC is disabled (who knows, it might be interfering somehow). Open an command prompt windows, as administrator, CD to the bin directory of the XC8 installation and run xclm.exe - you should see a few lines saying something like 'patching OK' (I don't remember exactly the wording). My XC8 installation is in this location: If this is still not working then I don't know what will.
LE: Actually there may be another way. I updated the attached file and added also the picc and pic18 files already patched. Maybe they will help you by replacing them in the installation directory. « Last Edit: January 18, 2017, 06:32:35 18:32 by mars01 » Logged.

What is the MPLAB Harmony Framework?. Apply settings to all users of this machine. Leave checked or uncheck if required in your environment. Add xc8 to the PATH environment variable. Not generally required unless you plan to use XC8 from the command line (terminal or script).
Add header file path to MCCINCLUDE environment variable (used by the MPLAB C18 tools). Required if you check either item below. Update MPLAB IDE to use the XC8 compiler for all existing C18 (mcc18) projects. Best to leave unchecked if you still wish to use the legacy compiler with older projects. Use XC8 for the C18 Linker, Librarian, and Assembler.
