I’m trying to use in the Olimex ESP32-EVB board the SD card and the SPI at the same time, and for me is impossible.
I know that the SD card uses SPI but without CS line, and also without instantiating the SD_MMC class, that I don’t understand that, but I use because I saw in the SD_MMC examples, and works fine.
The problem is when I read a sensor value in SPI, with a CS in the GPIO17, that runs fine but the next SD_MMC action, append, fails!
Can you help me!
Thanks.
