| PIC18f452 MCU control TC35I GSM module---Solved!! |
 Posted: Fri Oct 07, 2011 8:09 pm |

Hi guys ,
I designed a project that used the PIC18F452 control TC35I module.
The detail info. as follow:
Use the KEY control TC35I module "make a telephone, hang up phone, send the text sms, send the PDU sms".
When I compile it, it is OK, but I when download to target board, display error
ICD ERROR
Could not read target ROM: the returned address was not the onerequested
How I modify this code for successful ???
Appreciate !!!
The code as follow:
| Code: |
#include <18f452.h>
#include <string.h>
#fuses HS,NOWDT,PUT,NOPROTECT
#use delay (clock = 20000000)

#bit KEY1=PORTB.0 //ring up
#bit KEY2=PORTB.2 //hang up phone
#bit KEY4=PORTB.4 //send a text sms
#bit KEY5=PORTB.5 //send a PDU sms

When I use the 51 series chip, it is work OK !
These 2 code has only difference that the "char " string part.
The 51 code is
| Code: |
char code num[]="13820835529F";
char code sms[]="6E295EA6FF1A003300350043";
.........
|
The pic code is
| Code: |
char num[]="13820835529F";
char sms[]="6E295EA6FF1A003300350043";
..........
|
Who can tell me how to modify the pic code? Put the string into ROM. |

To put string data into ROM, you use the const construct. _But_, to then use a pointer to this, you need to have the command line up with the fuses, saying #PASS_STRINGS=IN_RAM
The key is to understand that the PIC, uses a Harvard memory architecture, meaning that it has multiple address spaces, one for ROM, and another for RAM, addressed at the same time (different from the PC, or most other micro controllers). Problem this brings, is that there are two address 0's. two address 1's etc.. One in each memory space. So if you put data into ROM, and then want to address it the code needs to 'know' that it must talk to the second memory space. There are two ways to do this:
1) Use the ROM construct rather than const. This adds extra code to extract data from ROM, and an extra bit to say which memory space the data is in.
2) Use '#PASS_STRINGS=IN_RAM'. This adds code so that string data stored in the ROM, is automatically copied into RAM as needed, and pointers can then be used to this.

First, thank you very much!
I use the 2) way to set the ROM, but when I download the code to target board, the ICD always display "Could not read target ROM: the returned address was not the one requested".
Why ? What means about this error ? |
