Proton24 SD File System

[Nickma]

Hi everyone
I am designing an SD Card recording device using the Proton24 SD FAT File System (by top204). Don't know how to set record of file attributes (date / time). If anyone has examples, please share.

Hi Nickman

This was written from GPS date and time received and was taken from Les's Examples.

Craig, thanks for the answer.
In your example, the time and date are recorded as data to be written to a file. These data are not ATTRIBUTES of the file. Time and date attributes are created via Global_bMinutes, Global_bHours etc. (see the FileSys.inc file in Includes for Proton24) My attributes are being written, but the data that I am trying to write is not written at all.

Hi everyone.

I'm stumped with writing the attributes of the data file being created. I tried many options, but nothing works.

As a result, I get: VL-101.DAT 08/01/2021 12:15
moreover, if I change the value of the day or month, then nothing changes. Only the year is recorded correctly.
I ask for help (especially from top204 as the author of the File System)

[Wimax]

The post is quite old, but I assign all the variables (Global_bSeconds etc.) just before writing to SD and the attributes are correctly saved.

Now I'm trying to reverse the problem...how to send to a serial port the directory list of a SD card with file name, extension AND creation date & creation time ?

[Nickma]

Hello Wimax. Can you provide a fragment of your program for recording data on an SD Card. I'm interested in where in the program you assign all the variables (Global_bSeconds etc.)

[Wimax]

Hello Nickma,

My date & time info come from an RTC: RTC_Day, RTC_Month, RTC_Year  and so on. I assign these variables to Global_bDay, Global_bMonth etc within FileSys24.inc library.
I modified FileSys24.inc as follows:

Code Select Expand

'--------------------------------------------------------------------------------------------------------------------------
' Set modified time & date for file
' Input     : Global variables contain the date and time
' Return    : pSectorPos
' Notes     : None
'
Proc FAT_SetFileTimeModified(pSectorPos As Word)

 '***************  ADDED ***************
 '**************************************
 
Global_bDay=RTC_Day 
Global_bMonth=RTC_Month 
Global_bYear=RTC_Year 

Global_bHours=RTC_Hour
Global_bMinutes=RTC_Minute
Global_bSeconds=RTC_Second 

    FAT_InsertByteIntoBuffer(pSectorPos, (Global_bSeconds / 2) | (Global_bMinutes << 5))    ' Create time & date - Seconds/Minutes
    Inc pSectorPos
    FAT_InsertByteIntoBuffer(pSectorPos, (Global_bMinutes >> 3) | (Global_bHours << 3))     ' Create time & date - Minutes/Hours
    Inc pSectorPos
    FAT_InsertByteIntoBuffer(pSectorPos, Global_bDay | (Global_bMonth << 5))                ' Create time & date - Day/Month
    Inc pSectorPos
    FAT_InsertByteIntoBuffer(pSectorPos, (Global_bMonth >> 3) | ((Global_bYear + 20) << 1)) ' Create time & date - Month/Year
EndProc

In this way, when I write to SD, the creation date & time are correctly written.
Let me know if this works 

[Nickma]

Wimax, thank you. I don't have a chance to check right now, but I hope everything will be OK.
