Needs serious rework/refactoring - -/* Introduction - * ------------ - * SD and MMC cards support a number of interfaces, but common to them all - * is one based on SPI. This is the one I'm implmenting because it means - * it is much more portable even though not so performant, and we already - * have the mbed SPI Interface! - * - * The main reference I'm using is Chapter 7, "SPI Mode" of: - * http://www.sdcard.org/developers/tech/sdcard/pls/Simplified_Physical_Layer_Spec.pdf - * - * SPI Startup - * ----------- - * The SD card powers up in SD mode. The SPI interface mode is selected by - * asserting CS low and sending the reset command (CMD0). The card will - * respond with a (R1) response. - * - * CMD8 is optionally sent to determine the voltage range supported, and - * indirectly determine whether it is a version 1.x SD/non-SD card or - * version 2.x. I'll just ignore this for now. - * - * ACMD41 is repeatedly issued to initialise the card, until "in idle" - * (bit 0) of the R1 response goes to '0', indicating it is initialised. - * - * You should also indicate whether the host supports High Capicity cards, - * and check whether the card is high capacity - i'll also ignore this - * - * SPI Protocol - * ------------ - * The SD SPI protocol is based on transactions made up of 8-bit words, with - * the host starting every bus transaction by asserting the CS signal low. The - * card always responds to commands, data blocks and errors. - * - * The protocol supports a CRC, but by default it is off (except for the - * first reset CMD0, where the CRC can just be pre-calculated, and CMD8) - * I'll leave the CRC off I think! - * - * Standard capacity cards have variable data block sizes, whereas High - * Capacity cards fix the size of data block to 512 bytes. I'll therefore - * just always use the Standard Capacity cards with a block size of 512 bytes. - * This is set with CMD16. - * - * You can read and write single blocks (CMD17, CMD25) or multiple blocks - * (CMD18, CMD25). For simplicity, I'll just use single block accesses. When - * the card gets a read command, it responds with a response token, and then - * a data token or an error. - * - * SPI Command Format - * ------------------ - * Commands are 6-bytes long, containing the command, 32-bit argument, and CRC. - * - * +---------------+------------+------------+-----------+----------+--------------+ - * | 01 | cmd[5:0] | arg[31:24] | arg[23:16] | arg[15:8] | arg[7:0] | crc[6:0] | 1 | - * +---------------+------------+------------+-----------+----------+--------------+ - * - * As I'm not using CRC, I can fix that byte to what is needed for CMD0 (0x95) - * - * All Application Specific commands shall be preceded with APP_CMD (CMD55). - * - * SPI Response Format - * ------------------- - * The main response format (R1) is a status byte (normally zero). Key flags: - * idle - 1 if the card is in an idle state/initialising - * cmd - 1 if an illegal command code was detected - * - * +-------------------------------------------------+ - * R1 | 0 | arg | addr | seq | crc | cmd | erase | idle | - * +-------------------------------------------------+ - * - * R1b is the same, except it is followed by a busy signal (zeros) until - * the first non-zero byte when it is ready again. - * - * Data Response Token - * ------------------- - * Every data block written to the card is acknowledged by a byte - * response token - * - * +----------------------+ - * | xxx | 0 | status | 1 | - * +----------------------+ - * 010 - OK! - * 101 - CRC Error - * 110 - Write Error - * - * Single Block Read and Write - * --------------------------- - * - * Block transfers have a byte header, followed by the data, followed - * by a 16-bit CRC. In our case, the data will always be 512 bytes. - * - * +------+---------+---------+- - - -+---------+-----------+----------+ - * | 0xFE | data[0] | data[1] | | data[n] | crc[15:8] | crc[7:0] | - * +------+---------+---------+- - - -+---------+-----------+----------+ - */ - -#include "SDFileSystem.h" - -#define SD_COMMAND_TIMEOUT 5000 - -SDFileSystem::SDFileSystem(PinName mosi, PinName miso, PinName sclk, PinName cs, const char* name) : - FATFileSystem(name), _spi(mosi, miso, sclk), _cs(cs) { - _cs = 1;
