hi

i am using mikroc compiler for my program and i am using p89v51rd2fn controller which has 64kb flash memory and my program is about 37 to 40 KB but some how it give error of not enough ram. I costruct 17 variables including array and for display purpose i also use graphical lcd which is 127*63. so if any one find solution please reply me.

thank you
 

Re: not enough RAM problem

This microcontroller has “only” 1024B of RAM, so maybe your compiler tries to tell you that during operation the micro will need more than 1kB of RAM and that is above its physical size ..

Flash (code memory) is not RAM, have a thorough look at the attached picture ..

I also think that Ian is right........ MIckroC while compiling would require more memory than we expect it to take........ :cool::wink:
