Core32 Reading sysex file from SD and send it via midi

[Phatline]

hi

my idea is:

put a *.syx on the SD-Card

put the SD-Card in a STM34F4 core

var a. Core recognizes a *.syx and send it out on Port 32 (Midi A)

var b. I activate something in the program (with a Dip switch for example) and now it loads up

 

for what:

in use with generic Midicontrollers (BCR2000) to transfair a CC-Layout that is fitting to the Midibox programm

 

for which project:

http://wiki.midibox.org/doku.php?id=msq-cc-bcr

 

what i have up to now...

char filepathL[8];				//Number of Pathsymbols tm/bcr.sys >>> 8 max! 

      MUTEX_SDCARD_TAKE;  statusDir = FILE_DirExists("syx"); MUTEX_SDCARD_GIVE;
      if(statusDir != 1) {MUTEX_LCD_TAKE; 
                          MIOS32_LCD_DeviceSet(0); MIOS32_LCD_Clear(); MIOS32_LCD_PrintFormattedString	("%s %d", "no bcr.syx", statusDir);              
                          MUTEX_LCD_GIVE;}
      if(statusDir == 1) {
		   sprintf(filepathL, "tm/bcr.syx");
        
           FILE_ReadOpen	(&midifile_fi, filepathL);
        
        //normally i then start by reading the content and transfair it into variables..... but happens if i have Sysexfile instead? how to tunnel this to midiport?
        
           FILE_ReadBuffer((u8  *)file_typeBank,  4);  //"MQ01" = 4 Positons
           FILE_ReadBuffer((u8  *)CC_SEQ,        32);  //Container for static not touchable Variables      
           FILE_ReadBuffer((u8  *)CC_Morph,     128);  //Container for morphable Variables  
           FILE_ReadBuffer((u8  *)Velo_Morph,   256);  //Here we have 8x32=256, 
           FILE_ReadBuffer((u8  *)CC_Store,     256);  //Here we have 8x32=256, 
           FILE_ReadBuffer((u8  *)MSQ_Store,  65536);  //Motion-Sequence-Data 8x32*256=65536  

           FILE_ReadClose	(&midifile_fi);
       MUTEX_SDCARD_GIVE

it was really simple:

insert in a the function which is scanned every 2 seconds, which checks the SD Card:

MUTEX_SDCARD_TAKE;   //SD-Card is now only for the following LINES reserved:
    statusSD = FILE_CheckSDCard();
MUTEX_SDCARD_GIVE;

    if (statusSD == 1) {// YES CARD! 
	MUTEX_SDCARD_TAKE;
    	FILE_SendSyxDump( "/bcr1.syx", 32, 45); //Send(filepath, midiport, paket rate)
	MUTEX_SDCARD_GIVE; 
}

or more readable without MUTEXes:

statusSD = FILE_CheckSDCard(); //check if card is connected

if (statusSD == 1) {  //YES CARD is connecdte! 
    	FILE_SendSyxDump( "/bcr1.syx", 32, 45);} //Send(filepath, midiport, paket rate)
