stm32h743zi DFSDM configuration in CubeMX

How do I configure the DFDSM peripheral using CubeMX?I do know about the application note AN4990 and have read it. I also saw this threadhttps://community.st.com/t5/stm32cubemx-mcus/stm32h753-stpms2l-dfsdm-pt100-example-using-stm32cubemx/td-p/172652a...

GPDMA Linked List in Secure code on STM32N6

Hi,The example for FSBL works as describedhttps://community.st.com/t5/stm32-mcus/how-to-configure-the-linked-list-mode-in-stm32cubemx/ta-p/693779But if the same approach is applied to Appli (Secure) code, the "User Setting Error" raised in DMA IRQ.I ...

Resolved! STM32 Stop FMC Request

I've setup the FMC peripheral of an STM32H7 to read registers from an FPGA by creating a faux SRAM interface on the FPGA.  This works just fine so long as the FPGA has no issues but if, say, the FPGA is unprogrammed or the FPGA data bus gets hung, th...

Resolved! STM32F407 VDDA-VREF+ difference

In the STM32F407 DS, ADC characteristics table has the following footnotes:IMO 2. follows from 3. (which is a more stringent requirement); thus 2. is redundant and confusing.JW
