garg29 · Mar 25, 2008

Hi guys,
i'm trying to learn gsm modem communicatin with microcontroller(pic16f877). in 'C' laguage.

I'm able to receive sms through gsm modem but only first few characters. I am defining a string as

Code:

unsigned char sms[50];

but if i try to increase the no. of characters and for that i try to define

Code:

unsigned char sms[100];

i get the following errors:-

Error[491] : can't find 0x85 words for psect "rbss_0" in segment "BANK0"
Error[491] : can't find 0x7 words for psect "temp" in segment "COMBANK"
Error[593] : can't find 0x2 words (0x2 withtotal) for psect "code_ptr" in segment "BANK0"

i tried using different bank

Code:

bank1 unsigned char sms[100];

but i still get the same resultts

Please help me out.

With best regards,
Garg

SMS Length problem

use PIC that has no banking like 18F if you have array of more than one bank memory size
or try using 16 bit pointer
