Enables reading and writing on SD cards.
|
|
Once an SD memory card is connected to the SPI interface of the Arduino or Genuino board you can create files
|
|
and read/write on them. You can also move through directories on the SD card..

Usage
|
|
-----
|
|
|
|
Enable :c:macro:`LV_USE_FS_ARDUINO_SD` and define a :c:macro:`LV_FS_ARDUINO_SD_LETTER` in ``lv_conf.h``.
|
|
You will need to initialize the SD card before LVGL can use it (i.e. :cpp:expr:`SD.begin(0, SPI, 40000000)`).
