Memory allocation!!

[rat16f88]

Am using a PIC 16f88 uC and
I need to have an array of 4x32 of chars
eg:-

Code: Select all

char buff[4][32];

it needs only 128 bytes if I am correct(?)

Without using the above array compiler says 328 bytes free & 90% of ram,
but I cannot compile the code it says Not enough RAM buff

is there a any mistake of me or what should I do?

Regards

Hello,

Multidimensional arrays are stored on consecutive addresses in RAM.
Since you are using PIC16F which ha banks with 96bytes, maximum two dimensional array that you will be able to implement is

Code: Select all

char buff[4][24]; 

Please consider switching to PIC18, they have better memory organization.

Best regards.
