Hi All, LPC2368 uController has SPI intarface and SD/MMC MCI intarface, where SD card supports both SD and SPI protocol modes.
If We want to work in SPI mode with SD card then what are the changes we need to do in examples source code provided by the KEIL.
Hi Martin, The example programs we downloaded from the nxp site for MCB2300 board. We are using the KEIL uVision3 limited version. In example programs we have MCI and SPI folders with source code.
If possible can you provide the MCI_LPC23xx.c and SPI_LPC214x.c files for reference.We haven't find the file with the path given by you.
Our main doubt is that SD/MMC card slot pins are connected to LPC2368 uController and SPI pins are also connected to uController.
Now how SPI controller and MCI interface will communicate when SPI mode protocol was used for SD card?
I think you need the commercial RL-ARM kit to get access to these files.
Hello embeddedusb Device,
As Per Westermark mentioned you need the commercial RL-ARM kit to get access to the files.
If you are using a MCB2300 evaluation board please check the schematics on http://www.keil.com/mcb2300/ to see which pins are connected to the SD/MMC card slot.
