Hi. First, I don’t know if this is the best place to make a question like that…
I’m planing to use an ATSAM’E5’ MCU on my new projects and I want to use a classic 4-wire SPI to interface between the MCU and the SD card (CLK, SS/CS, MOSI, MISO signals), and not to use the “SD/MMC interface” which has 4-bit data bus plus other signals.
Also I want to run freeRTOS on the MCU and use a SD card library (I need to define which lib will be) that can work using classic SPI interface between the MCU and the SD card.
Is that ok? Are there freeRTOS’s SD card libs that support 4-wire SPI interface?
