Excellent Example regarding the Guide for MicroSD Card Module.
I want to use the Olimex-Gateway and need to know how to implement a non standard pin out for the SPI interface to the SD Card.
SPI.begin(GPIO_SPI_CLK_14, GPIO_SPI_MISO_2, GPIO_SPI_MOSI_15, GPIO_SPI_CS_13);
and I called it before SD.begin(). but it failed.
Can the SD.h library be used with nod standard SPI pinouts?
How would I do this?
Please check this tutorial: https://randomnerdtutorials.com/esp32-microsd-card-arduino/#sdcardcustompins
It shows how to use non-standard pins.
I hope this helps.
