I am using the codewarior with processor expert I don't know form where to start with. First I want to do the normal data send and store and read the data and display it through UART.I guess that can be done without using the FAT32 files. I have done the SPI communication and for MMC/SD card I explored but didn't get much help . Any help will be grateful. I want to know What is the extreme limit for interfacing the SD card in terms of GB? and what is the maximum speed of data transfer can be obtained using SPI when we interface the SD card with K20 uc. </P><P></P><P>Regards</P><P>Amit Kumar</P></BODY></HTML> Mon, 21 Oct 2013 10:46:38 GMT Amit_Kumar1 2013-10-21T10:46:38Z MMC/SD card interfacing with FRDM-K20D50M board using SPI. https://community.nxp.com/t5/Kinetis-Microcontrollers/MMC-SD-card-interfacing-with-FRDM-K20D50M-board-using-SPI/m-p/289335#M11448 <HTML><HEAD></HEAD><BODY><P>Hello</P><P>I want to interface MMC/SD card to the FRDM-K20D50M board using SPI.
