Hello everyone.I want to connect a STLINK-V3MODS to a microcontroller STM32L031 using SWD protocol, I have tried the following the following conection:Is that enough to flash a program using stmcube mx?

Hello, I just upgraded my TouchGFX to 4.23.2. When I created a new dynamic graph, I can't show the X-axis label and Y-Axis label.May I know if I miss some settings? Thanks. 

Hello Gentlemen!I have edited this question, former question below just for clarity.New question: the ITM SWO printF-ing works with frequency of 4 MHz. I have searched every little PDF regarding my board (NUCLEO-U575ZI-Q) and i have no clue where you can find this number. Can anyone help me? The frequency in question is this one:       Former question (ignore) Spoiler (Highlight to read)I am just trying to make printF work over SWO. on my board, over STM32 IDE  Board number: NUCLEO-U575ZI-QThings i tried on the internet:1. dont forget \n sign.2. Make sure you have Solder bridge or whatever, to SWO: Internet provides lots of images of some table, where you have this SWO pin explicitely mentioned and said if its soldered or not. I never found this, but i did look at scheme, and everything related to SWO was present, no DNF3. You have to have your CoreClock config synchronized: The only thing i found is in this image. I used both 16Mh

Hello,We are developing a product based on a STM32WB5MMG. We have configured the SBSFU with OTA (Asymmetric with AES encryption scheme). Everything is working great and I have only one question that came to my mind during the last commit...The CBC key for decrypting/encrypting the code is stored in the KMS of the CPU2. The SBSFU is supposed to read from there the key to decrypt new updates. So, why is the key also embedded in the binary of the SBSFU itself, in the se_key.s file? Basically, anyone who has access to the repository can have access to the encryption key (and in our case, being a team with more than one developer and with the potential to collaborate with external parties, this is undesirable). (I'm going to remove the se_key.s from the repo in the meantime). But most of all, what is the point of using the KMS if the SBSFU image itself contains the key?I'm sure I've missed something and would be very grateful if someone could help me understand it.Thank you and best re

I'm attempting to run an OP-TEE Trusted Application on the STM32MP157F-DK2 running OpenST Linux version stm32mp1-openstlinux-6.1-yocto-mickledore-mp1-v23.06.21. I've followed the guides here and here, but both end up producing the following error when attempting to run the application:TEEC_Opensession failed with code 0xffff0008 origin 0x3What could be causing this problem? I'm running a fresh install of OpenST Linux and haven't made any modifications to the system other than those required to get the example running.

STM32H7 SeriesI am trying to upload Ardupilot to my board. The co-processor works just fine with the regular procudure but no matter how much I tried, could not get the firmware on MCU.I have tried with the regular upload process documented on LINK  . However, even Windows 11 and ubuntu 22.04 do not seem to recognize the device. The output of lsusb shows no sign of a device while windows does not have any idea of its existence.The board features STM32H75 as its MCU and STM32F301 as co-processor.

Hello! I want to ask in this routine! I read it This application shows how to the use the WKUP driver. In particular, the WKPUis configured to wake up the core and generate an interrupt on a falling-edgeof the source INT28. This source is connected to the push button SW_1. After toconfigure the WKPU, the application toggles the LED_1 and the LED_2 for 1,5seconds, then will move the core in STOP0 mode. Now, if the SW_1 is pushed, thefollowing events will occur:1. The core will wake up and will return in RUN mode, and LED_1 and LED_2 willstart to blink again.2. An interrupt will occur. The related callback function will switch-on theLED_3. But I still don't understand that button SW_1 is not used in the pinmap editor ! How does it wake up the CPU and make the LED work!

Hi,My goal is to dynamically change the phase shift between two output signals. Ultimately I would like to do this by rotating an encoder knob, but for the sake of simplicity a software change will do to simplify things. I'm using a Blue pill (STM32F103C8T6).TIMER 2 is set to Master:Slave Mode: DisableChannel1: PWM Generation CH1Channel2: Output Compare No OutputTrigger Output (TRGO) Parameters:- Trigger Event Selection: Output Compare (OC2REF)Output Compare No Output Channel2:- Mode: Active Level on matchTIMER 3 is set to Slave:Salve Mode: Trigger ModeTrigger Source: ITR1Channel1: PWM Generation CH1Channel2, 3, 4: DisabledThe code is simple:HAL_TIM_PWM_Start(&htim2, TIM_CHANNEL_1); // 1st output signalHAL_TIM_OC_Start(&htim2, TIM_CHANNEL_2); // phase shift valueHAL_TIM_PWM_Start(&htim3, TIM_CHANNEL_1); // 2nd output signalWhen hardcoded everything works great and I get a phase shift between signals. See the attached image.But to change it I have to reflash the MCU as I can

Hi all,I am using the NUCLEO-H7S3L8 board, and I looked for the schematic or wiring diagram for this board in the ST website, but I couldn't find it. Anyone knows where that information may be available. Thanks,Amilton

I stumbled across this problem:https://community.st.com/t5/stm32-mcus-products/unable-to-read-reset-values-of-the-stm32h730vb-octospim/m-p/212094In the current rev 3 of RM0468 https://www.st.com/resource/en/reference_manual/rm0468-stm32h723733-stm32h725735-and-stm32h730-value-line-advanced-armbased-32bit-mcus-stmicroelectronics.pdf I see this register bit:But the same register looks quite different in the STM32CubeProgrammer: Also, there's a typo in the table on Bit 19, must say OCTOSPI2EN Am I doing/expecting something wrong, or ist it a bug. If second, is someone reading here who can address it at STM?

Hello, I am trying to flash the MCU with USART bootloaderI am using the command codes from below link, but are not working for meCan someone help me validate of the command codes are correct for STM32G4https://www.st.com/resource/en/application_note/cd00264342-usart-protocol-used-in-the-stm32-bootloader-stmicroelectronics.pdf Current setup:I have connected the STM32 USART4 to my R PI device.

Hallo everybody, I have a question about the FDCAN peripheral of the STM32G0B1VC.I’m using the STM32Cube_FW_G0_V1.6.0 library and I have initialized the bus with AutoRetransmission:CanHandle.Init.AutoRetransmission     = ENABLE; During the transmission of a frame, when the ACK is not received the peripheral automatically resends the frame after a minimum delay (about 50 usec).Is there any way to increase the delay between the frames?When I repeat the test with a different platform, STM32F072VB and STM32Cube_FW_F0_V1.9.0 library, I have a different behaviour: the frame is retransmitted after 1.7 msec.Is there any way to increase the delay between the autoretransmitted frames with the STM32G0B1VC?Many thanksThomas 

Good morning,I have been following the stm channel board videos on the LoraWan examples. I was able to correctly configure and connect the board from the example provided in the MX “LoRaWan_EndNode”.But replicating the last video:https://www.youtube.com/watch?v=uYULivHQoNI&t=242sI get a current on the order of 350mA, far from its 2uA.Is there any practical and simple example on how to set RTC so that it goes into stop mode after TX?thanks for your help

Hi,While building the example FUOTA code from icubelrwan software expansion.

 Hello,I have a small problem when using a custom delay function as follows : void delay_us(uint32_t delayus) { uint32_t start_count = __HAL_TIM_GET_COUNTER(&htim2); while ((__HAL_TIM_GET_COUNTER(&htim2) - start_count) < delayus) { } }  The attached image shows the configuration of timer 2.This delay function should allow me to generate short pulses. except that sometimes it does and sometimes nothing happens when I use it. I don't know what the problem is. Could you please help me? 

Hi,      I am setting up an ble audio project with STM32CubeIDE。There is no ble audio choose with STM32_WPAN view in STM32CubeMX。I just can select the ble choose that is Starts from a skeleton project with host stack & GAP and GATT initialization。    I copy the audio directory that contais ble audio library and headers from origin STM32Cube_FW_WBA_V1.3.0 to My Project/Middlewares/ST/STM32_WPAN/ble directory。But when i regenerate code from STM32CubeMX，the audio directory will be empty. How should I configure on STM32CubeMX to avoid empty my audio directory？ Thanks

Hello forum, I'm starting to develop a smart robotic system, I wanted to base the movement part on an STM32 micro-controller,We thought about basing our SLAM on a camera and a simple distance sensor (and an IMU of course) for the initial mapping. the STM32U575ZI was supposed to support the DCMI interface and therefore is capable of handling such a task. but I just discovered that the Nucleo counterpart of the MCU isn't blocking the DCMI function. is there anything else I can do as a roundabout for this problem? maybe a different Nucleo that is more suited for such a task?thanks in advance

Hi I'm new to the STM32 series, I have a NUCLEO-F401RE and the X-NUCLEO-53L8A1. I am trying to edit the code from the X-CUBE-TOF1 SW package but run into the error below when compiling. Any ideas on how to resolve this issue?  Log output file: C:\Users\username\AppData\Local\Temp\STM32CubeProgrammer_a19188.logST-LINK error (DEV_USB_COMM_ERR)Encountered Error when opening C:\ST\STM32CubeIDE_1.14.1\STM32CubeIDE\plugins\com.st.stm32cube.ide.mcu.externaltools.cubeprogrammer.win32_2.1.100.202311100844\tools\bin\STM32_Programmer_CLI.exeError in STM32CubeProgrammerShutting down...Exit.

I think signal delay library does not work on MEMS Studio.I made an example code to show temperature values from a nucleo-L476RG and x-nucleo-IKS01A3 setup.The code should show the actual value and a delayed one:But it gives the following error:This exact situation was replicated on AlgoBuilder software and worked without any issue. Any idea how could I work this out?Thanks in advance

Hi,After updating STM32CubeMX to version 6.11.1, while configuring the ADC for the STM32H743, the oversampling settings now only allow pre-defined options. The generated code consequently employs pre-defined macros. However, the macro is not defined in , leading to a missing macro definition error during compilation.ADC_VER_V5_V90stm32h743xx.h

HI.Recently I purchased a stm32mp157-dk1. I am going to learn to use uboot. I know that Uboot startup is divided into several parts. The second part is SPL, and then SPL will boot uboot, and uboot will continue to boot the Linux kernel.I have read the STM32MP157 documentation and it says that STM32MP157 does not support SPL. Is this true? Is the SPL boot option never available or is it optional?

Hi!I notice something!In the devkit of STM32MP15xxxx, I found that ETH_TX_EN is used for GMII, but when I check the CubeMX, I found that RGMII is used instead. This is the settings for RGMII. In the devkit schematics, it is ETH1_TX_EN, not ETH1_TX_CTL.RGMII can only be selected as a mode.   This is the timing diagram for GMII and RGMII. The difference is that GMII has ETH_RX_ER and RGMII does not. And also ETH_TX_CTL is used in RGMII and in ETH_TX_EN is used in GMII. Question: Can it be that STM32MP15xxxx devkit schematic is using ETH_TX_EN as label for ETH_TX_CTL for RGMII? Also, there should be no pull-up resistor on ETH_MDC! Only ETH_MDIO.
