Problem with FC5_PIC_FAT16.c

[JCMB]

Compil to C OK but error while compiling to HEX.
-1 In MX_UINT8 Scan_Current_Folder:
if (Read_Byte_From_Buffer((Idx) + 2) == 0x00)
return MX_ACK_FILEEMPTY; //Address is empty
in MX_SINT16 FCD_FAT160_Scan_Current_Folder:
if (Read_Byte_From_Buffer((Idx) + 2) == 0x00)
return MX_ACK_FILEEMPTY; //Address is empty
instead of:
if (FCD_FAT160_Read_Byte_From_Buffer((Idx) + 2) == 0x00)
return MX_ACK_FILEEMPTY; //Address is empty
J replace it with:
i = Read_Byte_From_Buffer((Idx) + 2);
if (i == 0x00)
return MX_ACK_FILEEMPTY;

-2 in MX_UINT8 MX_Send_Cmd
RetVal = MX_SPI_BYTE(0xFF); //Wait for response of 1
MX_SPI_BYTE unknown !
J replace it with:
RetVal = %a_SPI_Master_Byte(0xFF);

Hi,

We know about this issue and the attached C code file should provide a fix for it. This file allows compilation, but the fix has not been confirmed on hardware yet.

If this fix solves the problem for you, please let me know.

Compiling OK.
Merci.

EB006-00-7 + EB037-00-1 + PIC18F4525 + FC 5.1 + SD Card Fat 16 (4 pieces):
Init_Fat() always return 255 !
Thank's for a quick help.

Hello,

This fixes the problem with the initialise routine.

I am now getting a problem where the file cannot be found on the card. Is it working ok for you.

I will see if I can get this problem resolved too.

Hi Benj

I've also been having trouble with the FAT component in FC5
See my recent post in the e-blocks section

Thanks

Hello,

Right I think I have found and fixed the problem.

1) There was a second bug in the FAT init routine though this was minor
2) There was a bug in the ToUpper function used in the format file string function.

Both of these problems have now been resolved.

The String file goes into the "Flowcode v5/CAL/PIC/" folder

The FAT file goes into the "Flowcode v5/Components/" folder

Fingers crossed your programs should work correctly now.
Let me know how you get on.

J did a few tests, it seem to be OK.
Thank's.
