I've generated a CubeMX project for a mass storage class device and can't seem to get the OTG_FS embedded pullup on DP to engage. I've enabled VBUS sensing, and can confirm that the code initially does a soft disconnect (OTG_DCTL->SDIS = 1) then a co...

My design uses an STM32H750 with a 24MHz crystal on the HSE, and on my first attempt, the crystal is not oscillating. I’m going through AN2867 and having difficulty finding any 24MHz crystal that meets the gain margin requirement for this processor.A...

Using the STM32F769 Disco, I've enable the external SDRAM using the FMC and can read/write that memory.I also have both SAI audio and microSD interfaces working with DMA, as long as the memory target/destination is internal SRAM. However, DMA transfe...

Posted on December 17, 2013 at 18:58I have an STM32F4 reading audio from a microSD, and am using the Standard Peripheral Library and the eval SDIO_SD.C code as a starting point. Things are working fine, but read rates are important for my applicatio...
