stm32f4 spi sd card without HAL
Hello,
I am using a custom board with stm32f411ce and I want to communicate with an SD card over SPI. I have written my own SPI library and I'm trying to write most of the code using registers. I have searched an SD example with registers and found out that I should use a library. I'm developing in Keil IDE and don't want to use Cube MX. can someone help?
Thanks
