STM32 U575 ADC1 differential channel configuration

I am having some difficulty configuring STM32U575 ADC1 for Differential inputs. The reference manual and auto-generated code seem to have conflicting information:The ADC1 Connectivity diagram from Reference Manual (below) indicates configuring Channe...

STM32H753 FLASH ECC Question. Always enabled?

Hey there everyone.I'm currently writing a bootloader for an STM32 device. The ECC functions on the flash controller are important to us, but the datasheet doesn't show whether it has to be enabled or not. And I cannot find any registers with an enab...

I wrote a code to use can bus for stm32f103rct6. It doesn't work on stm32f103rct6 but work on stm32f103ret6. Why? Can you help me?

How to calibrate the ADC of a STM32F7?

I am currently using a STM32F767ZI. As the function "HAL_ADCEx_Calibration_Start" is not possible for a STM32F7, is there any other funtion or method (e.g. calibrating manually) for an ADC calibration to increase its accurancy?Thanks for any help.

How can I make a STM32H7A3 UART work in loopback mode?

I have some simple polling UART code that works fine when connected to a GPS receiver. I send a command and get a response back. Now I'm trying something new and it would be convenient to work with RX and TX looped back (connected together) so I rece...
