FreeRtos +FAT Native API

Posted by jcbarbero on May 30, 2017

Hi everyone, I´m new in the FreeRTOS environment and I´m trying to work with the SDCard as a log space, I´ve succesfully read and written the logs but I haven´t found an api for check the space left on the SD, in other words, the space available in the SDCard. I´m using the FreeRtos +FAT Native API.

Does anyone know how can I do it?

Thanks in advance.

Hola Juan Carlos,

When you mount a disk partition, you create a FF_Disk_t. That object has an I/O manager, which you can find with:

~~~ FFIOManagert *sddiskioman( FFDisk_t *pxDisk ); ~~~

Please use the following:

~~~ FFIOManagert pxManager = sddisk_ioman( pxDisk ); / The following will give an indication of the free disk space: */ pxManager->xPartition.ulFreeClusterCount pxManager->xPartition.ulNumClusters ~~~

have a look at include/ff_ioman.h for all details.

Regards.
