Arduino for STM32

Afer some testing, using the sdfat libary i can succesfully write and read data from the sdcard, but only using a software spi. I'm totally lost, since documentation is pretty hard to understand (for me) and i would like to get rid of the software SPI and use instead the hardware SPI (it uses a lot ...

So, I'm developing a remote datalogger that both uses a LoRa transciver and a MicroSD card to store data locally. This is because the LoRa module, sends data in periods of 500ms to reduce power usage. My idea was to have this low-freq data be sent via LoRa, and also have a MicroSD card wich saves ...
