Hello, I'm trying to configure my SAI to receive TDM packets from my external ADC. For some reason, no matter what sample rate I choose, the real audio and error between selected is always 0. I've tried changing the clocks to the SAI1 module to 50 and 100 MHz, but it didn't change anything. Is this a visual bug with CubeMX or is it something with how I'm configuring the peripheral? Thanks.  

Good evening, I am trying to use a P-NUCLEO-IHM03 pack.I have generated the project using the X-CUBE-MCSDK version 6.4.2 and STM32cubeMX version 6.17.0, built and flashed the project on the board. The problem is that as soon as I try to start the motor in ST motor pilot, I get a driver protection fault instantly, without any movements of the motor:

Hello!I am studying the SPC58NH92E7.I'd like to clarify some terms and definitions. Below, I’ll explain how I understand these terms. Please correct me if I’m wrong.Project examples in SPC5Studio are divided into two classes: "RLA" and "cut2_RLA".RLA here is Register Level Access, correct?What does it mean "cut2"? Lock-step core (vs "cut1" regular core)?Some of the examples are for FreeRTOS, and some are for OSLess. Does "OSLess" here mean that the example doesn't use an operating system? After all, "OSLess" isn't the name of a specific operating system, is it?

For SPC582B, which development IDE is recommeded for code debug and run? Does PLS JTAG debugger software ok to run some demo when using SPC582B-DIS discovery board?

Hello,  I tried developing for the NUCLEO-WBA25CE1 using BLE_HeartRate, but even after selecting it, the Next button is disabled. Could you please suggest a good way to develop for this board?  

Excuse me, how can I implement this kind of loadingI'm really at a loss for ideas. Please help me out, thank you

Ciao, [English was established as the common basis so that everyone in the global community can understand each other (see ST Community Terms and Conditions - STMicroelectronics Community, article 10)] I recently purchased a new STEVAL-L99615C evaluation board and, before connecting any battery pack, I checked the resistance between the cell inputs and ground (GND). I measured: C1 → GND: a few ohms C2 → GND: a few ohms C3 → GND: a few ohms C4 → GND: several megaohms C5 → GND: several megaohms C0 → G

Hi all, I'm planning to use USB (DFU mode) for production programming of the STM32C071K8U6 — including the very first firmware upload. The board has no external crystal; I intend to rely solely on the internal RC oscillator.   A few questions: 1) Is USB DFU feasible on this specific part without an external crystal? I've read that not all STM32 variants support USB boot without an external crystal (due to clock accuracy requirements for USB). Can anyone confirm whether the STM32C071K8U6's internal oscillator is sufficiently accurate for this?   2) Are there any specific hardware or configuration requirements I should be aware of for first-time USB DFU programming on this part? As the moment I just have the two USB traces connected to the USB connector but no 5V (VBUS) connected anywhere to the micro. I also have a pushbutton on the BOOT

Hello everyone,I'm using STM32CubeIDE 2.1.0 and STM32CubeProgrammer on Ubuntu 24.04.4 LTS.Yesterday I was able to flash my firmware to an module based on the STM32H755 MCU via ST-LINK using the following settings:Port: SWDMode: NormalReset mode: Software resetEverything worked fine. Today I made some modifications to the firmware, but when I tried to connect again, I got this error:Error: No STM32 target found!

Hello,I would like to ask about the current status of Bare-Metal support for the Cortex-A35 core on the STM32MP2x platform (STM32MP257F-DK).While searching the ST Community, I came across the following discussion related to this topic:https://community.st.com/t5/stm32-mpus-embedded-software-and/stm32mp257f-dk-bare-metal/td-p/787100Since that discussion is now more than one year old, I wanted to check whether there have been any updates regarding Bare-Metal development support on the STM32MP2 platform.When creating a project in STM32CubeIDE for the STM32MP257F-DK, I could not find an option to create a Bare-Metal project targeting the Cortex-A35 core.Could you please clarify the following:Is there now an offic

Hi, i experimented the following configuration STEVAL-MKBOXPRO with BLEMLC code available within FP-SNS-STBOX1 package. For my specific application, i want to increase the BLE transmit power of the BlueNRG-LP chip of the MKBOXPRO. So i modified the code with the aci_hal_set_tx_power_level(1,31) +8dBm (since default value was  aci_hal_set_tx_power_level(1,4) -16dBm). Everything is fine with compilation with Cube IDE. But in practice with the app ST BLE Sensor v5.2.6, the real connection distance still remains about 25m, with a disconnect when RSSI is about -92dBm. These values are correct but what is not correct is that any tries to change aci_hal_set_tx_power_level with different "theoretical" power levels (from -54dBm to +8dBm) do not change anything in practice. It looks like aci_hal_set_tx_power_level has no effect on "real" transmitted poser. Any help will be welcomed to this topic. Thanks reading et thanks in advanc

Hi, I am currently implementing an HTTPS server using mbedTLS 3.6.5 and LwIP on an STM32H7S7L8 platform running FreeRTOS.Our mbedTLS configuration  are fully functional, as we already have a stable, working TLS implementation on an MQTT client using the same stack.However, we are encountering an issue during the TLS Handshake phase on the server side after configuring the client sockets to non-blocking mode (O_NONBLOCK). While the listening socket correctly accepts incoming connections, the handshake loop fails.I have attached the relevant snippet of our server thread implementation, including our I/O callbacks.Could you please review our non-blocking I/O logic and handshake loop to see if we missed a specific configuration requirement or state handling for mbedTLS 3.x in server mode?

Hi, we have purchased stm32h750vbt6 microcontroller for analog signal validation with 10k potentiometers to integrate with game controller joystick especially joy.cpl using windows 10 OS.   We have dealt with DMA Circular mode configuration pointing cortex-M7 DRAM to 0x30000000 to retrieve the analog signals associated with respective 10k potentiometers. Totally we have four analog pins such as PA0,PC0,PA3 and PC5 from ADC1 & ADC2 with proper distinguished rank allocation alongside desired maximum sampling cycles but although we have altered and tested with different values of this above configuration it ended up with ADC channel leakage which is declared 16 bit ADC.    Moreover we have tried adding external 100nf capacitors to avoid these linkage but failed.    We kindly request you to resolve the ADC channel leakage in our current stm32 Project. Our entire stm32 project attached for your reference and fault ide

I am using the Analog Devices EVAL-ADE9430 Evaluation board for testing one of their devices. The Evaluation board uses the NUCLEO-144 STM32F413ZH processor. I am using the Keil uVision development setup to run and debug code.  I am specifically concentrating on the SPI Bus Driver and the timing. I have no previous experience with STM Devices and how the SPI transfers happen in the processor. so I apologize a head of time.  My question is very basic I am trying to understand how the NUCLEO-144 STM32F413ZH board is transmitting the data over the SPI Bus. What setup is involved and what kicks off the actual transmission in the the HAL_SPI_Transmit() code below. The code i am using is transmitting 8 bits at a time.  The Chip Enable (SS) is set active prior to this code. I see a structure called hspi that has a bunch of parameters that are initialized at line 29 below By single stepping know when line 1

is there a way to search for which stm32h7 mcus have integrated HS usb phy?the mcu finder product selector doesn't have such filter, is there an app note, a product brief or anything like that?How is one supposed to find such a controller? (besides manually checking all of them)Sometimes this is the main and only selection criteria. I didn't even know that such a feature even exists.I just stumbled uppon when i saw that the stmlink v3 has high speed usb but doesn't use an external usb phy.

Hello, I am working on a project using DMA and UART HD to communicate between multiple MCUs.  I have an issue where when one MCU starts up, it momentarily interrupts the UART HD bus and sometimes causes a UART and/or DMA error.Since I am using the STM32CubeMX packages for the HAL libraries, I tried to recover from the issue by several means, but I noticed there seems to be no provided method in the stm32h5xx_hal to recover once hdmarx->State = HAL_DMA_STATE_ERROR.  Calling any of the UART or DMA abort functions (HAL_UART_Abort(), HAL_UART_AbortReceive(), HAL_UART_DMAStop()) does not reset the DMA State.  The call chain for HAL_UART_Receive_DMA() eventually checks the DMA State and just returns an error.I have found 2 methods that manage to work around the issue, but I am not satisfied with them because they are not at all elegant:Method 1: Call HAL_DMA_DeInit(), reset the Parent pointer back to huart, then call HAL_DMA_Init().  I feel

Hello, I am trying to import the RTSP example for the NUCLEO-N657X0-Q. It is not appearing in the IDE as a choice, but I see the project in D:\STM32\STM32Cube_FW_N6_V1.3.0\Projects\STM32N6570-DK\Applications\VENC\VENC_RTSP_Server 

I'm looking for a working example of how to program the OTP memory on the STM32H573.I am looking to program with TrustZone enabled, from secure mode.  I'm using STM32Cube_FW_H5_v1.4.0, and am not in a good position to move to v1.5.0.  Any working example would do, using HAL, LL or direct register access.Thanks in advance.-Rob

Hello all, I've been having trouble with the ADC system on the STM32G071G8U6.  I'm using the STM32CubeMX to generate initialization code.  I have 5 external A/D inputs and it appears I am not getting readings anywhere near the real values, so I have switched to trying to just read the internal reference.  I hope that if I can get the internal reference or the temperature to read correctly, I'll be able to solve the problems with the external inputs. My VDD is provided from a 2.5 volt LDO.  Looking at it with a DVOM, that looks accurate. I am running the A/D at 12 bit resolution and my clcok prescaler is Synchronous clock mode divided by 2.  I have the sampling time set to the maximum available in Cube, 160.5 cycles. I have a polling routine running every 1 second that reads all 5 external and all 3 internal channels. I set the VREFEN and TSEN bits in the ADC CCR register at the end of init and leave them enabled. I r
