You find all other commands, for example to write data to the SD card, in the specification. There are also a set of application commands. They are sent by first sending the application command with the ID 55, then a second command with the ID of the application command itself Initializing the SD Card Now, as far as sending the commands are concerned, there is an order in which they must be sent. Only the commands, CMD0, CMD1, ACMD41, CMD58 and CMD59 will be accepted when the card is in its idle state. Sending any other command will likely to yield an illegal response
SEND IFCOND (CMD8) is used to verify SD Memory Card interface operating condition. The card checks the validity of operating condition by analyzing the argument of CMD8 and the host checks the validity by analyzing the reponse of CMD8. The supplied voltage is indicated by VHS filed in the argument SDIO cards support most of the memory commands of SD cards. SDIO cards can be structured as eight logical cards, although currently, the typical way that an SDIO card uses this capability is to structure itself as one I/O card and one memory card. The SDIO and SD interfaces are mechanically and electrically identical. Host devices built for SDIO cards generally accept SD memory cards without I. SD commands are issued to the card in a packed command frame, a 6-byte structure sent over the SPI port. The command frame always starts with 01 followed by the 6-bit command number. Next the 4-byte argument is c Michigan State University, 2004. Application Note Secure Digital Card Interface for the MSP430 F. Foust Dept. of Electrical and Computer Engineering sent, MSB ˝rst. The 7-bit CRC. The steps to switch the SD card into SPI mode should therefore be as follows: Power-up. • Send at least 74 clock pulses to the card with • Set CD line low. • Send 6-byte CMD0 command 40 00 00 00 00 95 to put the card in SPI mode

A brief explanation of practical SD library's commands is provided in the following table: *file is an instance from File class. You can find more information about the SD library Here. How to Use SD and Micro SD Card with Arduino? Tip The module. The SD library allows for reading from and writing to SD cards, e.g. on the Arduino Ethernet Shield. It is built on sdfatlib by William Greiman. The library supports FAT16 and FAT32 file systems on standard SD cards and SDHC cards. It uses short 8.3 names for files. The file names passed to the SD library functions can include paths separated by forward-slashes, /, e.g. directory/filename.txt. Es existieren diverse Varianten (miniSD, microSD), die zur normalen SD-Card weitgehend kompatibel sind. Die Karte liest das anliegende Datenbit mit der steigenden Taktflanke ein, als SPI-Modi eignen sich somit Mode 0 (CPOL=0, CPHA=0) und Mode 3 (CPOL=1, CPHA=1) (siehe auch Serial Peripheral Interface) Once the SD card receives a command it will begin processing it. To respond to a command, the SD card requires the SD CLK signal to toggle for at least 8 cycles. Your program will have to toggle the SD CLK signal and maintain the MOSI line high while waiting for a response. The length of a response message varies depending on the command. Most of the commands get a response mostly in the form. If you need to change this so that you can edit the contents of the SD card, you should change the state of the SD card.
