Detailed Description

SdReader class

Macro Definition Documentation

◆ SPI_INIT_SLOW

#define SPI_INIT_SLOW 0

Some SD card are very sensitive to the SPI bus speed for initialization. Try setting SPI_INIT_SLOW nonzero if you have initialization problems.

Set SPI_INIT_SLOW nonzero to reduce the SPI bus speed for SD initaizaton to F_CPU/128. F_CPU/64 is used if

◆ SPI_DEFAULT_HALF_SPEED

#define SPI_DEFAULT_HALF_SPEED false

Default card SPI speed. Change to true for Wave Shield V1.0 The SPI speed is 4 Mhz for 'true' and 8 Mhz for 'false'.

◆ SD_READ_TIMEOUT

#define SD_READ_TIMEOUT 300

read timeout ms

◆ SD_CARD_ERROR_CMD0

#define SD_CARD_ERROR_CMD0 0X1

timeout error for command CMD0

◆ SD_CARD_ERROR_CMD8

#define SD_CARD_ERROR_CMD8 0X2

CMD8 was not accepted - not a valid SD card

◆ SD_CARD_ERROR_CMD17

#define SD_CARD_ERROR_CMD17 0X3

card returned an error response for CMD17 (read block)

◆ SD_CARD_ERROR_CMD24

#define SD_CARD_ERROR_CMD24 0X4

card returned an error response for CMD24 (write block)

◆ SD_CARD_ERROR_CMD58

#define SD_CARD_ERROR_CMD58 0X5

card returned an error response for CMD58 (read OCR)

◆ SD_CARD_ERROR_ACMD41

#define SD_CARD_ERROR_ACMD41 0X6

card's ACMD41 initialization process timeout

◆ SD_CARD_ERROR_BAD_CSD

#define SD_CARD_ERROR_BAD_CSD 0X7

card returned a bad CSR version field

◆ SD_CARD_ERROR_READ_REG

#define SD_CARD_ERROR_READ_REG 0X8

read CID or CSD failed

◆ SD_CARD_ERROR_CMD8_ECHO

#define SD_CARD_ERROR_CMD8_ECHO 0X09

bad response echo from CMD8

◆ SD_CARD_ERROR_READ_TIMEOUT

#define SD_CARD_ERROR_READ_TIMEOUT 0XD

timeout while waiting for start of read data

◆ SD_CARD_ERROR_READ

#define SD_CARD_ERROR_READ 0X10

card returned an error token instead of read data

◆ SD_CARD_TYPE_SD1

#define SD_CARD_TYPE_SD1 1

Standard capacity V1 SD card

◆ SD_CARD_TYPE_SD2

#define SD_CARD_TYPE_SD2 2

Standard capacity V2 SD card

◆ SD_CARD_TYPE_SDHC

#define SD_CARD_TYPE_SDHC 3

High Capacity SD card
