Hello, in the STM32H753xI datasheet, Table 11, "Total current into sum of all VDD power lines (620mA)," is the voltage condition VDD = 3.3V? I would also like to know the current at VDD = 1.8V.

I am trying to capture data from the LINE_IN (blue jack on board), but I am not receiving the correct input. I evaluated my output at the oscilloscope and noticed that I am not receiving the sinusoid I am injecting; the frequency is correct, but the data appears clipped, as shown in the picture. I tried to reduce the Vpp, but it just started getting noisy instead of giving the correct input.My second test was to record on the sd card, and the problem persisted; I am only getting data above zero and noiseI am using the BSP library stm32h735g_discovery_audio.c, and to get the correct frequency that I was inputting, I modified these values in the BSP_AUDIO_IN_Initmx_config.FrameLength = 64;//changed: prev:128 mx_config.ActiveFrameLength = 32;//changed /An changed the number of slots like this:hsai->SlotInit.SlotNumber = 4; /* WM8994 TDM mode: 4 slots */I also tried to modify these registers from the audio codec directly, but nothing seems to make it work:* Disable mute on IN1L_TO_

Hello, as in the title I'm facing issues with high intensity BLE transfers (~4 writes and 4 reads and indicates per second) on X-NUCLEO-ST67W71 paired with STM32N6570-DK.Randomly during the transfer I'm encountering this error which simply breakes the communication with ST67:ST67 Log: [ERROR] [1055938] [spi_xfer_engine] (spi_iface.c:448) waiting for spi txn ready timeouted ST67 Log: [ERROR] [1057938] [spi_xfer_engine] (spi_iface.c:448) waiting for spi txn ready timeouted ST67 Log: Timeout waiting for tx ST67 Log: [WARN] [1058941] [ST67Task] (st67_app.c:1138) Set read data error!

Hi I am trying to use the AEK-POW-BMSWTX to read cell voltages from an Optipower OPR50006S50 Lithium Ion battery.  I only want the cell information, not interested in battery management itself.  I'm using SPI2 from an STM32G474RE. I have spliced pin C0 to the GND EXT pins and the GND terminal of the battery, then used C1 through C6 for cell wires. C6 is spliced to C7 through to C14, finally the positive terminal of the battery is connected to VBAT. The issue I am finding despite no MISO comms from the board is LED D2 goes off after 60 or so seconds. My SPI function is as below: void BMS_Read(uint8_t *rxBuf, uint16_t len) { uint8_t wake[5] = {0x55,0x55,0x55,0x55,0x55}; uint8_t rxBuf[8]; HAL_GPIO_WritePin(SPI2_BMS_CS_GPIO_Port, SPI2_BMS_CS_Pin, GPIO_PIN_RESET); HAL_SPI_Transmit(&hspi2, wake, 5, HAL_MAX_DELAY); for (uint16_t i = 0; i < len; i++) { uint8_t dummy = 0xFF; HAL_SPI_TransmitReceive( &hspi2, &dummy, // generate clock &rxBuf[i],

I have a project that is using custom hardware with a STM32G0B1CBT6 processor.  The code is developed using STM32CubeIDE and STM32CubeMX.  However, there are times when I am unable to run a debug session and I'm seeing (very) occasional Hard Faults.I have a diagnostic serial port and have successfully modified my Hard Fault Handler to dump additional information out that port.So what I'm after is some code that can read registers and/or the stack to provide additional information that I can use (along with the map file, etc) to determine where my Hard Fault is happening.Can anyone point me in the right direction?  All my searches have shown me code that references registers I can't seem to find in the docs.Thanks.  

Can force a specific DR for LoRaWAN?I tried using: uint8_t custom_dr[7] = {0};custom_dr[3] = 1;lorawan_api_dr_strategy_set(USER_DR_DISTRIBUTION, STACK_ID);lorawan_api_dr_custom_set(custom_dr, STACK_ID);   but did not work.

Hi,I am setting up SBSFU on our STM32H750. I want to test the RDP and WRP security protections.Steps taken so far:I have enabled WRP and RDP Level 1 by setting the option bytes through cubeprogrammer and enabling SFU_WRP_PROTECT_ENABLE & SFU_RDP_PROTECT_ENABLE in app_sfu.hI have enabled SFU_TEST_PROTECTION in app_sfu.h Note:There are several test cases in sfu_test.c that I am using. The tests in questions are attached below:TEST_ERASE_FLASH is failing.  Output:I am not sure why this would be. Does anyone have any advice? 

Hi everyone,I am struggling to get MotionFX (9-axis sensor fusion) working on an STM32L476G-DISCOVERY board using the onboard LSM303C (Acc/Mag) and L3GD20 (Gyro).The Problem: Despite the library being initialized and updated in the main loop, all outputs (data_out.rotation, quaternion) remain strictly at 0.0.Current Status & Observations:Hardware CRC: Enabled and verified. The CRC->DR register changes value constantly, proving that MotionFX_update is processing data.Timing: The loop is running at 100Hz. I've tested with both a calculated dt and a fixed dt = 0.01f, but the output remains zero.Input Data (data_in):Acc: ~1.0g on Z-axis when flat (normalized to g).Gyro: Normalized to dps (values around 0-5 dps at rest).Mag: Values around -500 µT (normalized using 0.58f LSB for 16G scale).Memory: mfx_buffer is 2450 bytes and aligned to 32-bit (uint32_t array).Configuration: * mfx_knobs.output_type = MFX_ENGINE_OUTPUT_NED;Library enabled in both 6X and 9X modes.

Hi all,I connected my SPV1050 chip as you can see in the picture and started to measure my circuit. It looks pretty good. I powered it up with 3.3V at IN_LV. And I can measure a voltage of about 2.416V at the STORE pin. And even the LDO2_EN pin got a 2.412V, but at the LDO2 pin there is nothing. Does anyone have any idea why this might be the case? Even when I connect the Battery, nothing changes.

Hi everyone,I’m currently working with the CR95HF and looking into using the provided DLL (CR95HF.dll) for PC-side communication.From the documentation and software packages I understand that a DLL is provided to interface with the CR95HF demonstration board (). However, it seems this DLL was originally built for older environments and is typically installed in x32 systems, which suggests it may be a 32-bit library.I searched the community and found a previous discussion where someone asked about x64 compatibility ( Solved: CR95HF DLL for x64 - STMicroelectronics Community ) and was provided with source code instead of a precompiled DLL.So my questions are:Is there now an official x64-compatible version of the CR95HF DLL available?Or is the recommended approach still to request/use the source code and rebuild the DLL for x64 systems?If rebuilding is required:Is there any official guidance or updated project for generating a 64-bit version?Thanks in advance for your help!

Hello , i would like to know how can we set the pwm channels in stm32cubemx as well as the serial wire debug , because i want to set up a project with  STM32C5A3RGT6 but under the debug we have no 2 wire serial wire debug option. Edit: Moved from Introducing STM32CubeMX2, a new flavor of STM32CubeMX tool

Hello,I have two technical questions regarding the lis3dh accelerometer behavior and interrupt configuration.1) Are the values I read from the LIS2DUX12  in m/s²????  Exemple :::Accel [LIS3dh] 28807220458ns (-7.300384, -1.942303, -5.712095)2) Interrupt logic (INT1_CFG :: XLIE / YLIE / ZLIE)When I configure an interrupt threshold, for example 5 m/s², and enable the axis event bits in INT1_CFG XLIE / YLIE / ZLIEDo the Low events correspond to the following type of comparison?X < threshold, Y < threshold, Z < thresholdOr do they correspond to:|X| < threshold, |Y| < threshold, |Z| < thresholdFor instance, if I have the following measured values and the interrupt threshold is set to 5 m/s²:Would this condition trigger an interrupt or not, according to the configured AOI ,XLIE / YLIE / ZLIE  (i put 1 for this register)???Accel [LIS3DH] 29380340576ns (-18.442175, -19.566559, -19.461311)Thanks for your response

Hi,I am using IIS2ICLX MEMS accelerometer in an IOT device.The IIS2ICLX is soldered on a PCB that sends data to internet every 10min.To measure the zero-g level of both x and y axis, I suspend the device from the ceiling so that the PCB (and the accelerometer) is perfectly horizontal and and vibration-free.I noticed that the zero-g level changes if I briefly touch the device, and wait for the device to return to its horizontal position (the temperature of the device does not change).Does anyone has an explanation ? I there a way to minimize this effect by using two redondant accelerometers, with a 90 degre rotation between them ?Thanks for your help.

Hi,I'm using STM32H5F5LJHxQ. External HSE Oscillator is 48MHz. RTC clock mux is set to HSE_RTC, divider set to "/48" and the tool shows correctly that RTC clock is 1000kHz (48MHz / 48).During my tests I discovered a wrong RTC time, error ~2%. (1.2 seconds deviation per minute)In the generated function HAL_RTC_MspInit() is see: (49 instead of the expected 48)PeriphClkInitStruct.RTCClockSelection = RCC_RTCCLKSOURCE_HSE_DIV49; If I change the configuration in CubeMX to create a divider of 47, the correct RCC_RTCCLKSOURCE_HSE_DIV47 is generatedIf I change the configuration in CubeMX to create a divider of 49, the correct RCC_RTCCLKSOURCE_HSE_DIV49 is. generated.If I manually set the correct RCC_RTCCLKSOURCE_HSE_DIV48 in the sources, the RTC runs correctly. Regards,Gunnar BohlenHMS Networks 

Hi. I have been looking at the internal operation of MEMS devices and am looking for information on how this sensor takes the reading from the mechanical parts. I am trying to find out if this sensor uses capacitive sensing or frequency drift and time period for one sample to be acquired from the MEMS structure. The available documentation does not list much information of this and any additional information would be great. Thanks.

I have project consisting of FSBL+Application (writing AI code in application), I want to debug application code, but unable to do it . My core doubt is should I go via FSBL debugging or Application debugging while working with real time detection in AI ? I am very much confused in this application debugging, kindly address it.I have ensured the external memory loader in cube Programmer as well as in debugger settings is same & loaded .I had flashed the binaries in cube programmer FSBL-trusted bin at 0x70000000 and application trusted-bin at 0x70100000 and signed them also. I have attached a word document having screenshots of debugger settings and problems coming in debugging for each directly application and via FSBL. & one screenshot of external memory settings in .ioc file.Thanks & RegardsChanchal

Hello everyone. I would really appreciate if someone could help me sort out a really annoying issue i have with a new STM32WB5MMGH6 based board i made.On this board i have two sensors connected to the same SPI interface (hspi2) with different CS pins to address the sensors. Here's the schematic sections of the two sensors : MS5607 :  LSM6DSV320XTR with an auxiliary IIS2MDCTR tied directly to it (for the test board, the magnetometer is not soldered yet):I'm currently on test phase, and the MS5607 is responding correctly. But the LSM6DSV320XTR does not respond at all. i'm not even getting the whoami ID (i get a 0).For the SPI configuration i have this : For the 2 Chip Select pins i have this config :   I don't understand where the problem comes from. Could someone help me asap ? I'm losing hope :(

Question split from this thread. Hi ,  Can you also provide some info on how to set pwm through timer channels ?

Hello ,   I was planning on using the new STM32C5A3RGT6 for my new project but after reading the comments regarding the stm32cubemx2 , i am reconsidering this decision. I also saw that zephyr is providing support for stm32c5.    My question would be then what would be a good source for learning stm32cubemx2 because coming from stm32cubeide 1.17 it is a big change.

Hi everyone,I am running into a persistent debugging issue with a generated STM32Cube AI Studio application on the NUCLEO-N657 board. The debugger seems to drop the connection when transitioning from the "FSBL" to the main application "Appli" , and subsequently locks up.My Environment:Board: NUCLEO-N657IDE: STM32CubeIDE v2.1.1Tool: STM32Cube AI Studio v1.1.0Note: The code is generated properly from STM32Cube AI Studio, and the model .hex file is downloaded successfully to the NUCLEO board: The Issue:During the first time debugging the program, it starts correctly.I run the "FSBL" application, and it executes properly.As soon as the execution jumps from "FSBL" to "Appli", the IDE throws a "Target is not responding" error.On any subsequent attempts to debug, it does not work at all and throws the error shown in the attached image.
