Connect your SD card to ESP module

SD pin ESP8266
  1. DAT2 | -
  2. /CS | Any accessible GPIO (15, 5, 4, 0, 2, 16)
  3. DI | HMOSI (GPIO13)
  4. VDD | +3V3
  5. CLK | HCLK (GPIO14)
  6. VSS | GND

Add extras/sdio and extras/fatfs to EXTRA_COMPONENTS parameter of your makefile, e.g.

EXTRA_COMPONENTS = extras/sdio extras/fatfs

Use const char *f_gpio_to_volume(uint8_t gpio) to get the FatFs volume ID based on GPIO which is used for CS pin.

FatFs configuration

Almost all of the FatFs parameters are configurable in the Makefile of your project. See default values and their meaning in defaults.mk.
