* @file sd-test.ino
|
||
|
|
* @brief MicroSD card test for the Hosyond 2.8" ESP32-S3 Display. The slot
|
||
|
|
* is wired as 4-bit SDIO (not SPI) on non-default pins, so it needs
|
||
|
|
* SD_MMC.setPins() before begin() - see ESP32S3HosyondDisplay.h in
|
||
|
|
* arduino-audio-driver for these pin numbers (shared with that board's
|
||
|
|
* addSDMMC() bring-up).
|
||
|
|
*
|
||
|
|
* Writes a small test file, reads it back, and lists the card's root
|
||
|
|
* directory.
