Resolved! SPI mode and UHS-II mode not supported for STM32U5xx
Hello,I have a very basic question. In the spec of the U5 series there is this: Does that really mean that the U5 would not support talking to an SD card in SPI mode? I find it hard to believe since SPI seems to be the most basic way to interface wi...

Migrating from L431CCU6 to F412CEU6
Hello,I'm planning to migrate from L431CCU6 to F412CEU6 MCU and as per CubeMX, all the pins and power scheme matches. But I see there is Vcap on pin 22 of F412 MCU. Is it okay to skip it with below setup? Adding this cap will need redesign and we wan...

Resolved! STM32H750 FMC + LCD
I’m having some trouble related to using the FMC to interface with a LCD. We are using NE1 as chip select, LCD register select is A0, 16 bits of data. When I’m scoping the signals, I’m seeing the A0 go high during 16 bit writes to 0x60000000 (comman...
Resolved! AES v SAES
Hello,The STM32U585 Reference Manual say these chips have one AES and one SAES peripheral. In turn each of these have an "AES core algorithm (AEA)" component. I expect that to mean that there are two physically independent AEA's on the chip. Is that ...
Resolved! How to recover continuous data with DMA ?
Hello,I have a program that works in DMA but I would like to put a function to know when the transfer in the DMA is finished so that I can recover the data continuously. Do you have any information on this ? Here is part of my code HAL_SAI_Register...

Resolved! ADC output ranging about 2000 up to 4095
I'm running an STM32L452RCTX uC, and I'm trying to implement a 2.5Vref+ ADC.Things weren't looking quite right on the pins I intend to implement, so for now I'm driving a floating TP with a power supply so I can directly test input vs output.When dri...
