## How to use
|
|
|
|
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
|
|
7. DO | HMISO (GPIO12)

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