Hi All,
My MCU can't support me to declare large enough memory to store my byte arrary data, what can I do?
Could you please advice?
Thank you very much!
Best regards, Boki.

Stating the obvious, use a different processor, add more memory, or optimise your program.
If you get down to this then i would suggest your application is not supportable on your current hardware, and you are on a hiding to nothing anyway.
Good luck!

I think we need some more details on your problem; what memory are you short on, RAM, ROM ? What kind of data do you need to store, and how do you want to access it ? Apart from adding memory (which might or might not be possible on your platform) you could try some tricks with compression or storing your data in another way.

With lots of unused cpu power, you could consider compressing the memory contents.

Buy a bigger one.
HTH HAND.

Ah, the ever-cryptic Boki strikes again. Details?

Hire somebody with a clue.

Figure out how much memory you need before choosing the micro.
Always a challenge.......

That's always the problem with arrary data. It's too much and it don't fit.

Clear procedure to improve problem.
Thanks a lot.
Best regards, Boki.
but, there are no too many similar data ...
and I have to program the algorithm first, and it also occupy memory, am I right? :)
Best regards, Boki.
In fact, it is not a MCU.
it is a RF CHIP, and can run C language.
Best regards, Boki.
Hi All,
I foudn the chip provides programmer to use a function to allocate a memory block and return a pointer, when I got a pointer, I don't know how to assign variable continually,
/* GetPointer(T) is a function that allocate memory size (T) and return the pointer(byte) */ ex: Now, I have to assign data as:
unsigned char *A = 0; A = (unsigned char *)GetPointer(255);
A[0]=123; A[1]=312; ... ... A[255]=xxx;
Is that the only way? Thank you very much for your kindly advice!
Best regards, Boki.
Hello Boki,
Please, *please* quote the appr> but, there are no too many similar data ...
We might be able to help you with this, but you still have to provide some details for that. What kind of project are you working on, what processor are you using, how much RAM/ROM/FLAST/etc is available there, what data are you trying to store, etc etc
Ofcourse, but there's different kinds of memory; since we do not know anything about your platform, we can not give you any hints on decreasing code or data size. If you want help, tell us more.
