storing DATA in MikroC Avoid Error Not Enough RAM and Strings problem (const truncated) Most of the Microcontrolleres having limited RAM, For Avoiding the Errors Not Enough RAM and Strings problem (const truncated) .You have to move the strings to ROM (FLASH program) memory, and there by save RAM.In MikroCif the string is declared as constant - compiler will move it to ROMThis is the way in which const truncated problem can be solved ifgreat number of strings was used that was located in RAM.How we can impliment it in MikroC, see the exampleFirst you declare the followingchar text[15]; // this is stored in RAMconst char *mesg1="shibuvarkala1234"; // this is stored in ROMconst char *mesg2="CE http://forum.mikroe.com/viewtopic.php?f=48&t=51598 Attingal"; // this is stored in ROMhere is the function for copying string before the usage ,copy the following function to your code( Received from Mikroelecronica) :// --- Copying strings from ROM to RAMvoid strConstCpy(char *dest, const char *source) {while(*source)*dest++ = *source++ ;*dest = 0 ;}you have to use the above function to access the strings stored in ROM,strConstCpy(text,mesg1);LCD_Out(1,1,text); // Now output is shibuvarkala1234strConstCpy(text,mesg2);LCD_Out(1,1,text); // Now output is CE Attingal Posted by shibu V http://www.shibuvarkala.com/2009/02/how-to-use-rom-for-storing-data-in.html at 7:11 PM Labels: Microcontroller, PIC 4 comments: jamal said... hi im jamal from karachi, pakistan,using ccs compiler forpic16f877a,what do i type code to generate PWM April 20, 2009 at 10:57 AM NetoMX said...

The compiler which i use is MikroC... when i compile the program it https://ccsinfo.com/forum/viewtopic.php?t=51295 shows not enough RAM.... what i have to do... Help me...

People have done that project with an antique PIC16F84A with tons of options without any problem. All you need is compact your code.

Also MikroC free demo version has a limit on ROM and RAM. So you will quickly run out of RAM if you are using the function Lcd_Out("Blah") to do all your menus. There are many ways to get around this, they are all commonly discussed on the MikroC forum. You can just write single characters to the LCD (instead of using text strings) this is probably the easiest solution. You should probably search the MikroC forum on mikroe.com for all the LCD threads. Roman Black - PICs and electronics.

Build Failed. Halting build on first failure as requested. BUILD FAILED: Tue Oct 08 15:40:01 2013 While with V4 compiler this program worked OK. I must say that in V4 the program memory was at 98% is there a way to solve this problem?

Remember on PICs they are very different memory spaces. You need to through your code and minimise the number of variables, both global and local. On most PICs there is no data stack so all local variables have to be statically allocated in RAM. That's why PICs can't really do recursion or re-entry into routines. You need to make sure all variables are the minimum size to fit the required data. There's no point in having int32 when the values go from 0 to 100. Clearly int8 would do. Reduce the number of floats or replace them with carefully scaled 16 and 8 bit integers. As a bonus, the code will run faster and will generally be more precise. Reduce the number of temporary variables. Ensure all structures are arranged so as to allow easy alignment. int32s and int16s need to start on even byte boundaries. Thi
