I am having issues flashing and debugging through the cubide software, and keep getting no target device found. My initial thoughts were I dont have the correct firmware upgrade and drivers however I am trying to download the cubeide programmer/ stws-link007 and 009 for a nucleo-f767zi off https://www.st.com/en/evaluation-tools/nucleo-f767zi.html#tools-software and in all cases whether I chose "get latest" or chose an ealier version I'm met with the following page. I dont see any mention of the site being down but all softwares are doing this, does anyone have any tips?note: I have a Windows x64 system

 STM32F103C8T6 CAN Not Responding — UART to CAN TestI’m testing a very simple setup with two STM32F103C8T6 (Bluepill) boards.The goal is just to send data from my PC to one STM32 through UART, and then transmit it over CAN to another STM32 board.SetupData flow:  PC (PySerial) → UART → STM32 (Transmitter) → CAN Bus → STM32 (Receiver) → UART → PC  Hardware used:Two STM32F103C8T6 boardsMCP2551 CAN transceivers120 Ω termination resistors at both endsCommon ground between boardsUART baud: 115200CAN bit rate: 1 Mbps (Prescaler = 2, BS1 = 15, BS2 = 2)What’s WorkingThe PC is successfully sending UART data using Python (PySerial).The STM32 transmitter receives the data correctly — UART works fine.The DMA callbacks trigger as expected, showing that data reception over UART is confirmed.What’s Not WorkingThe CAN bus is not showing any transmission or response.The transmitter’s CAN doesn’t seem to send anything, even though initialization completes without errors.The receiver b

I am looking for a motor driver / evaluation board recommendation.My application requires a 3-phase inverter stage for driving a BLDC/PMSM motor.Key requirements are:Input Voltage: 20 V – 30 V DC (nominal 24 V system)Power Stage: 6 separately controllable MOSFETs (3-phase inverter)Control Interface: I want individual gate control for each MOSFET (I will generate my own PWM/FOC control signals).Load: BLDC / PMSM motorCurrent Rating: Medium power (please suggest boards with scalable current capability)I am not looking for an integrated driver IC performing FOC internally — I specifically need access to each gate input so that I can run my own motor control algorithm.If ST has any evaluation boards, power stages, or MOSFET gate driver boards that match this requirement, please recommend model numbers or links.Thanks!

 Hello,Requesting marking ID confirmation "456RQ-K317" for St. Micro MPN: M24256-DRDW3TP/K. 

Hi Everyone,I am facing an issue where my Blue Pill development board (STM32F103C8T6) is not being detected by ST-LINK V2 when using either STM32CubeIDE or STM32CubeProgrammer.Both tools consistently show the “No STM32 target found” error message. I have two Blue Pill boards and two ST-LINK V2 programmers, and I am facing the same issue on both setups, which makes me believe it’s not a wiring or hardware fault on a single unit.My Hardware Setup:Boards tested: 2 × Blue Pill (STM32F103C8T6)Programmers tested: 2 × ST-LINK V2 (Firmware version: V2J34S7)Target voltage: ~3.1V (as detected by STM32CubeProgrammer)Connections:3.3V → VCCGND → GNDSWDIO → SWDIOSWCLK → SWCLKSteps Tried:Verified all SWD wiring and signal continuity using a multimeter.Tested both “Hardware reset” and “Software reset” modes in STM32CubeProgrammer.Updated ST-LINK firmware to the latest version (V2J34S7).Switched between multiple USB ports and cables.Verified target power (3.3V stable).Ensured BOOT0 = 0 (Normal boo

Hello, I am a Master’s student doing an internship on physical-layer modelling of G3-PLC using the ST8500 (ST G3-PLC hybrid solution, AN5603). I have two technical questions that I could not resolve from the public documentation: PGA / AGC on ST8500The datasheet states that the PGA gain ranges from –18 dB to +54 dB with a 3 dB step, but I cannot find the exact mapping between the internal PGA code and the gain in dB.For the ST7580, there is a “PGA gain table” (code 0…8 → gain in dB).Could you provide the equivalent information for the ST8500 (table code → gain or a formula and code range) so that I can interpret the AGC value correctly?AGC attribute in CENELEC profilesIn AN5603, the attributes PHY_LASTRECEIVEDPACKETAGC / PHY_PHYCURRENTAGC are marked as “only FCC”.Is there an equivalent AGC attribute for CENELEC profiles, or another recommended quantity (e.g. based on SNR/LQI) to characterise the receive level/quality in CENELEC?  These details are important for

Hi me and my team signed up for Innovation Fair. Today was the day of announcement of results, yet I have not received any mail regarding that. When will the results be announced?

I’m facing an issue while debugging my STM32F103C8T6 (Bluepill) board using ST-LINK V2 and STM32CubeIDE. The connection and flashing both seem successful, but the program doesn’t actually start running on the board.When I check the console log, I noticed that STM32CubeIDE isn’t flashing my project’s .elf file  it’s flashing a temporary .srec file created by the GDB server instead.I have checked the run and debug configuration and verified. path is pointing to the correct location where .elf file is created.Here’s the relevant log output: STMicroelectronics ST-LINK GDB server.

Dear STMicroelectronics Community,I hope you are doing well.I am currently reviewing the datasheets for your STR1550 and STR2550 transistors. While both documents provide detailed electrical characteristics, I noticed that the collector-emitter cut-off current (ICES) is not specified.Could you kindly confirm the ICES values for both the STR1550 and STR2550?This information is important for our qualification and comparison process.Thank you in advance for your assistance.Best regards,MahdiL 

I am creating a program to write data arbitrarily to the M95M04. The M95M04 has 512-byte pages, but does writing have to be done in page units?For example, when writing 8 bytes of data starting from address 8, is it acceptable to specify address 8H and write 4 bytes? Or do I need to read 512 bytes from address 0, modify the 4 bytes of data starting from address 8, and then write back all 512 bytes? thank you 

Hi,I am trying to understand some features of STHV200 Dual channel ±100 V, high voltage 3 A linear amplifier and 2 A pulser transmitter.I could not find a detailed datasheet of the product. Only data brief. I want to use it to amplify the received low voltage signal. The data brief mentions an internal amplifier but I could not understand how it works. Am I able to amplify the received signal coming from the T/R switch? Or is the internal OP-AMP configurable for example as a differential amplifier?  

From the listed applications, it is noted that RF3L05150CB4 is suitable for HF and VHF communication ranges. However, the available application note mentions frequencies at 520 MHz and 860 MHz. Is there any application note available specifically for HF and VHF ranges?

Our customer has requested a material declaration report for M93C86-WMN6P. We purchased 1,000 pcs from Avnet back in 2016. However, it appears that this part is now inactive, as I couldn’t find the part number listed under M93C86-W. Could you kindly provide the material declaration report for M93C86-WMN6P? Additionally, could you advise if there are any alternate parts available? Would M93C86-WMN6TP be a suitable replacement? M93C86-W | Product - STMicroelectronics Thank you for your assistance.

The board has passed a authentication test so I currently believe it is a me issue. I have been trying to get a CAN bus going using the STM32 Blue Pill board with a TJA1050 CAN Transceiver, but for some reason even with basically copy pasted example code I don't even get activity on the lines. The transceiver modules I am using has the CAN bus terminating resistors built in resulting in a 60ohm resistance between the H and L lines. I've ended up putting together a basic test Tx and Rx bread board in hopes of figuring out whats going on with no clues. The Tx loop eventually goes dead for some reason which makes me think the HAL_addTx started locking up. Linked is a github repository with both projects. Also a video of the boards. 

I am attempting to use STPOWER Studio to run a thermal simulation but every time I start a simulation it just sits at 0% complete, showing Simulation in progress: iteration counter [ 0 / 63]. Has anyone run into this problem?  Any suggestions on what might be the issue?This is my configuration:I/O Summary: STGIPNS3H60T-H Simulation Parameter STEP_0 PWM Modulation-Steady State-Simulation Time15 sDC Link Voltage300 VRMS Phase Current1 AOutput Power216.37 WOutput Voltage156.15 VOutput Frequency60 HzSwitching Frequency21 kHzPower Factor800 mModulation Index850 mAmbient Temperature25 °C

Please help me to get full datasheet for part#STHV64SW.Is there any need for an NDA?What is the process?

Hello,I’m using an STM32H562RGT6‑based board with a built‑in ICM‑20948 IMU and ICP201xx pressure sensor. When I run bare‑metal code (no RTOS) the I2C communication with both sensors works fine and I can read data. However, as soon as I enable FreeRTOS (Arduino core), the program prints “Initializing IMU...” and then stalls inside myIMU.init() (similarly ICP.init() stalls if I try that). In bare‑metal the same init completes and data is available.What I’ve observed and triedI2C scanner (bare‑metal): devices found at 0x64 (ICP) and 0x69 (ICM).Minimal bare-metal IMU example: init() returns true and I get accelerometer values.With FreeRTOS: prints "Initializing IMU..." and never reaches "ICM20948 connected." or the error print.I tried:Creating IMU with explicit Wire pointer: ICM20948_WE myIMU(&Wire, 0x69);Configuring Wire.setSDA / setSCL / begin before initMoving init() into an RTOS task after scheduler startReducing task stack sizesChecking heap with xPortGetFreeHeapSize().this code (

I have a question regarding the use of the STSAFE-A110.Currently, the default I2C address of the STSAFE-A110 is set to 0x20. It is possible to change this address?If it is possible, could you please explain how to do it? Thank you in advance for your assistance.
