Re: [avr-gcc-list] array of string pointers in progmem

[Slawomir Kawalek]

I do it in the following way:

1. for one string:
 const char szErrorInfo[] PROGMEM = ("Error");

 

2. for table of strings:

 

#define CMD_HELP             "HELP"
#define CMD_HELP_CHAR  "?"
#define CMD_EXIT               "EXIT"
#define CMD_PASSWORD  "PASS="

PGM_P szProgMemCommands[15];

 

void InitSetup( void)

{

 

 BYTE iCnt=0;

 

 szProgMemCommands[iCnt++]=PSTR( CMD_HELP);
 szProgMemCommands[iCnt++]=PSTR( CMD_HELP_CHAR);
 szProgMemCommands[iCnt++]=PSTR( CMD_EXIT);
 szProgMemCommands[iCnt++]=PSTR( CMD_PASSWORD);
 ...

}

 

 

Maybe it could be possible to make it easier but it also works...

Subject: [avr-gcc-list] array of string pointers in progmem

 

Hi.
I want to do following
Create array of pointers to strings in program memory. Strings also must be in program memory.

 

I try following:
PGM_P str_table[] PROGMEM = { "ERROR", "OK" };

 

I get

 

00000026 <str_table>:
  26:   61 00 67 00

 

Contents of section .data:
 800060 01455252 4f52004f 4b00               .ERROR.OK.

 

Compiler put pointers to prog memory but I can't make him to put string there.

 

Any Ideas?
Thanks.
