Hi, I'm working with SD card memory device and this week I received suggestion to use SD-card example of board ek-lm4f232 on stellaris Launchpad. After check this code I identify that file: mmc-ek-lm4f232h5qd.c has all definition to connect hardware and firmware ( Is this information is True?). After check code I see that prpbabily is necessary change spi funcions to file system FATFS work well:
For example: On spi master code of Launchpad stellaris were, the code use:
SSIDataGet(SSI0_BASE, &ulDataRx[ulindex]); and SSIDataPut(SSI0_BASE, ulDataTx[ulindex]); and EK-lm4f232 use
ROM_SSIDataPut(SDC_SSI_BASE, 0xFF); /* write dummy data */
ROM_SSIDataGet(SDC_SSI_BASE, &rcvdat); /* read data frm rx fifo */
I need change functions?
Thanks too much
