STM32F429I-Disco with SDCard
Moderator: RoccoMarco
Re: STM32F429I-Disco with SDCard
Since I was asked by a PM, here is my working code.
First a simple main.c to test you configuration and then the configuration for GPIOC and GPIOD. Please note that I renamed the pin defines to fit their new function.
