again encountered with not enough RAM

hi

i am trying all the way to solve my problem by removing most of the error still 1 error not allow to my program to compile s
that is as below

here i strike with word '?lstr9 which is not used in my program so what it does mean?

Hi,

Based on this error report, I can assume that some literal string in weather_1.c file is using more RAM,
so there is no RAM left for the remainder of the program.

Try optimizing your code so it fits in the MCUs RAM memory, or if this is not possible, use a MCU with more RAM.

Regards,
Filip.

Hello I have a problem

I wrote a program which is use the One wire, Glcd, and some own functions.
When i build the program without using the Glcd , it's running perfectly, but when i use the Glcd funtions i got errors.

Without Glcd:

I've got this errors

Not enough RAM, Why?
Please help me, what can i do?

Hi,

Please, like I said earlier, try optimizing your code so it fits in the MCUs RAM memory, or if this is not possible, use a MCU with more RAM.

I switched from a large memory model to a small memory model and the "362 RAM error" went away??? Im using the 89S51 CPU
FYI..Im really a newbie and have very little time with this program but I know that my code was correct and fought this for hours

[outThere]

from what i understand the large memory model takes into account external ram where the small memory model is only RAM on the processor so w/ the large you were inadvertently trying to write to non existent external RAM.
