Problem Porting TLS CLient from F207 to H743

I managed to get a simple TLS client working on the NUCLEO-F207ZG. I cannot get the program to run on the NUCLEO-H743ZI2. On Wireshark I see several DHCP DISCOVER messages go out; followed by an OFFER message coming back. My code never responds with ...

Do SPI pins ever float?

When I used buffers between CPU and SPI peripherals I got problems. There were no Pull-ups.Bare GPIO pins with pull ups work. So do SPI pins float between transfers?CPU happens to be STM32H750/STM32F746 if it matters.

Which STM32 part has the fastest ADC sampling. Is there any MCU with 1+ GSPS. Is there any way for me to use an stm32 to sample 4 inputs at 50MHz analog BW each?

I am trying to sample 4 inputs at 50MHz analog BW. Which STM32 MCU can support this? Does it have a fast interface to stream that data out?

STM32H7 HAL ADC with DMA Init ends in Error_Handler (CubeMX)

Hello, I am using an STM32H743VIH6 in a custom board. The MCU is running with 3,3V. I generated code for the MCU with CubeMX and configured the clock, ADC1 and the DMA. Attached the generated main.c file. Inside the fuction " MX_ADC1_Init" the Error_...

SPI1 on pins PA5, PA6, PA7 does not transmit and receive data when used in DMA enabled mode for NUCLEO-F303RE.

I am trying to get the SPI communication with DMA enabled mode for STM32F303 controller using nucleo board NUCLEO-F303RE. For this, I am using one board as SPI master and other as SPI slave. Pin connections on hardware (as per nucleo board):Pin 8 on...

LL_RTC_WaitForSynchro function in LL drivers

Hi,While using STMCube Drivers version 1.24 for STM32F4 processor, I discovered the following:LL_RTC_WaitForSynchro function that waits for RTC Shadow registers to be updated, often times returns error on timeouts. The timeout values set is 1 second....

Hi, Does ST Microelectronics have any BacNet stack implementation for STM32 series controller? Also can you suggest the microcontroller/processor from STM that support opensource BacNet IP?
