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?
Resolved! Why is my SPI slave only sending one byte?
I am trying to read the position of an absolute rotary encoder (AMT22B-V). I have it connected to a Nucleo G474RE board. In the main.h file of the STM32CubeIDE project, I have the following declaration:#define BUFFERSIZE (COUNTOF(aTxBuffer...
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....
Execute nLog(n) algorithm in real time
Hey,I am planning an algorithm that needs to work in Real time.The system includes an ADC that samples in rate of 5Msps and the interface with the CPU is 80MHz in SPI.From primary calculation the running time Complexity is O(n log n), and the result...
What is the cheapest solution to add WLAN/BT to a STM32F4/F7 MCU?
Good afternoonLooking for a simple solution to add WiFi and/or BT connectivity to a STM32F4/F7 MCU..USB dongles are out of question as it would require to a Linux system...Seen that some people are using ESP32 hooked up to UART...but I am not sure if...
Keil uvision
hi everyone, i would like to know if anyone has faced the same probleme : so i'm working with keil uvison5, i have build usart2 (PA2-->Tx / PA3-->Rx), everything works, and the message is printed correctly in the serial monitor, but when i'm trying t...
