SDHC card filename

[petesmart]

Hello,

A quick question. Is it possible to set the filename time and date info?... Using create file sets the file create time and date to a date in 1989.


Thanks

Pete

Hi Pete,

Looking at the FAT component the creation time and modify time should be the date and time of compilation but this does not seem to be happening. When I get some time I will see if I can get this fixed.

A way to change / override the values would also be nice so I have added a SetTimeAndDate macro which allows you to override the values.

This page details how the time and date values are formatted to work with the FAT file system. http://www.maverick-os.dk/FileSystemFor ... TimeFormat

I've now managed to fix it so the defaults will now be the compilation time and date.

That's brilliant Ben,

I will try this out and come back to you...

Hi Ben,

Dropped the component into the FC 6 component folder and came across a problem which resulted in error messages on compile. If you update a component in an existing flowchart based on the original component is there anything specific that you must do in order to update that specific component within the flowchart? I'll explain further below



Loaded an existing flowchart based on the original FAT component. Hit the compile button and received the following error messages:

Code: Select all

ZTE test rev.fat test.c:300: error: 'FCVsz_07fa1_FAT1__FILE_HANDLE' undeclared here (not in a function)
ZTE test rev.fat test.c:308: error: 'FCVsz_07fa1_FAT1__SIM_FOLDER_PATH_4' undeclared here (not in a function)

ZTE test rev.fat test.c:316: error: 'FCVsz_07fa1_FAT1__SIM_FOLDER_PATH_0' undeclared here (not in a function)

With the original FAT component the flowchart compiled with no errors

Interestingly, I tried an experiment where I created a new flowchart. With just the FAT SDHC component it compiled with with the same errors

I'm using an ECIO40P16 - properties see below

Interested in your thoughts

Hi Pete,

Thanks for letting me know. In changing the time and date to variables I forced all variables to be exported which for some reason also forced in the simulation variables into the output C code. I've had another pass and removed the sim variables again and it's compiling as expected again now.
