Hi,I was wondering if it's possible to use FatFs with SD Card as extended SRAM, or maybe by setting the FMC to map to the FatFs or SD Card in some way. I have a project that uses an RGB Display of 480x272 (RGB565 mode), so the RAM space needed is 130...

MCU wakes-up from standby mode by external signal on the wake-up pin (PA0). Also, the RTC alarm does produce an interrupt when NOT in standby mode (callback function does send some characters to UART). BUT, if the MCU is in standby it cannot wake-up ...

I can wake-up the STM32F103 from standby mode with an external signal on the PA0 pin. Also, the RTC alarm produces an interrupt when the MCU is not in standby mode, but when the MCU is in standby mode I cannot get it to wake-up with the RTC alarm.

Posted on October 25, 2017 at 15:45Hi, I'm currently trying to make SD card work with FatFS on a custom made PCB with STM32F429. I create the init files with CubeMX 4.22.1 and although I set the SD interface to be 4 bits long, I find this code in th...
