uController is running out of memory or something else ...

[PICfan]

Hi there,

I have been trying to write an example wherein I can use all the Mmc_FAT16 function of the Mmc_FAT16 library, for learning purpose. However, when I tried to use the following function (Rename_folder()), I get an error which leads me to belief the my Micro runs out of RAM or Flash memories. Even I ordered new microcontrollers with higher memories. Is it really lack of memories that I get the following errors? I am not sure why these function should take or require so much memory? Thanks
I use easyPIC 7 with PIC18F45k22 microcontroller.

void Rename_folder()

Hi there,

However, when I tried to use the following function (Rename_folder()), I get an error which leads me to belief the my Micro runs out of RAM or Flash memories. Even I ordered new microcontrollers with higher memories. Is it really lack of memories that I get the following errors? I am not sure why these function should take or require so much memory? Thanks
I use easyPIC 7 with PIC18F45k22 microcontroller.

While I was experimenting, I noticed that the more line of UART1_Write_Text( I have, I get that RAM error. When I try to run more than 5 of the following code, I get the error of 31 362 Not enough RAM 'f16_sector' __Lib_MmcFat16Constants.c. Is there a better way of displaying a menu?

Code: Select all

void show_menu_UART()
{
  UART1_Write_Text("\r\nMake a choice:\r\n");
  UART1_Write_Text("1.Make Folder/Directory (B0)\r\n");
  UART1_Write_Text("2.Delete folder (B1)\r\n");
  UART1_Write_Text("3.Rename a folder (B2)\r\n");
  UART1_Write_Text("4.Make Folder/Directory (B0)\r\n");
 /* UART1_Write_Text("5.Delete folder (B1)\r\n");
  UART1_Write_Text("6.Rename a folder (B2)\r\n");

  UART1_Write_Text("13.Rename a folder (B2)\r\n");
  UART1_Write_Text("14.Make Folder/Directory (B0)\r\n");
  UART1_Write_Text("15.Delete folder (B1)\r\n");
  UART1_Write_Text("16.Rename a folder (B2)\r\n");        */

Hello,

This code takes RAM memory for each string because String Literals are stored in RAM in this case.
Literal strings are not always stored in RAM. Compiler will store them in flesh memory if you pass them to const char pointers.
You could make wrapper routines for library functions.

Code: Select all

void UART_Write_const(const char *txt){
char loc_text[__MAX_STRING_LENGTH];
char * dst;

  dst = loc_text;
  while (*dst++ = *txt++)
    ;

  UART1_Write_Text( loc_text);
}

Best regards.

Thanks for you response. Your function is a little bit complicated for me for now. I will try that later. However, you gave me good idea of putting the strings in a constant. Well I put them in a constant but I got errors and then just put them in character var, as shown below. The problem of RAM seems gone. Thanks

Code: Select all

void show_menu_UART()
{
  char MakeChoice[22]="\r\nMake a choice:\r\n";
  char MakeFolder[32]="1.Make Folder/Directory (B0)\r\n";
  char DeleteFolder[24]="2.Delete folder (B1)\r\n";
  char RenameFolder[26]= "3.Rename a folder (B2)\r\n";
  
  
  UART1_Write_Text(&MakeChoice);
  UART1_Write_Text(&MakeFolder);
  UART1_Write_Text(&DeleteFolder);
  UART1_Write_Text(&RenameFolder);
}

The above saves RAM but the following saves considerably more.

Code: Select all

void show_menu_UART()
{
  const char MakeChoice[22]="\r\nMake a choice:\r\n";
  const char MakeFolder[32]="1.Make Folder/Directory (B0)\r\n";
  const char DeleteFolder[24]="2.Delete folder (B1)\r\n";
  const char RenameFolder[26]= "3.Rename a folder (B2)\r\n";
 
 
  UART1_Write_Text(MakeChoice[22]);
  UART1_Write_Text(MakeFolder[32]);
  UART1_Write_Text(DeleteFolder[24]);
  UART1_Write_Text(RenameFolder[26]);
}

You can also store all your text strings in eeprom (internal or external)
I have to output a lot of texts without sd card.
I write simple program for PC that converts all text to eeprom with 0x00 byte separator. I read it from memory with simple function with search by CRC16 hash

It save a looot of RAM and ROM and allow to use single pointer variable for all strings
