A project using a SD/SDHC/MMC memory card as storage device is set up as explained in Create an Application Using the File System. To make use of a memory card drive please set File System:Drive:Memory Card to at least '1'. From the Drivers Component, please select MCI (API) and also SPI (API), depending on the actual connection of the card drive to the microcontroller. When you are finished with the configuration, click OK to apply the new RTE settings to your target. The Project window should look like the following:
For a proper memory card drive operation, you need to set the drive characteristics in the FS_Config_MC_n.h file. The following table shows the most important settings in that file:
Name | Definition |
---|---|
MCn_SPI | Select the SPI mode that is to be used |
MCn_FAT_JOURNAL | Enable the Journaling to protect the drive from data loss |
MCn_DEFAULT_DRIVE | If no other drive letter is specified, M0: is used as the default drive |
