First time working with an STM32 black pill.  I have a circuit that connects a Raspberry PI (3b) to the STM32.  I am getting errors when attempting to program it using openocd via the SWD lines.  I suspect it is a voltage issue, but I don't know how to verify.The STM32 is supplied 5v from a mini buck converter.  I measured 5v on the STM32 pins.On initial bootup, it comes up at 3.3v, and then rises to 4.2v.   This seems bad.   The rPI's 5v and 3.3v lines measure correctly.  There are no additional power sources other than the main 12v input on the PCB.Upon booting of the pi, an initial openocd command is issued to query the device.  this partially works:Open On-Chip Debugger 0.10.0+dev-01141-gc33d9efa (2024-12-11-17:24) Licensed under GNU GPL v2 For bug reports, read http://openocd.org/doc/doxygen/bugs.html Info : only one transport option; autoselect 'swd' none separate Info : BCM2835 SPI SWD driver Info : SWD only mode enabled Info : c

Hello,I built a test circuit similar to one provided in the TDE1747 datasheet (Figure 3). During testing, I observed that immediately after powering on, the power supply voltage appears at both inverting and noninverting terminal of the IC. This behaviour is consistent across two different TDE174 ICs.Could you please help identify the possible root cause of this issue? Thank You.

Hello Team,Kindly provide reference material like startup sequence and handling HFDA802 IC.I want to use HFDA802 audio IC with controller but startup sequence and steps are not mentioned in attached datasheet.if possible kindly provide reference sample code or steps to use IC with any controller.

Hi there, For my project, I'm use an M24M01E-F I2C EPPROM. I found Four addresses (0x50, 0x51, 0x58, 0x59) with the below mentioned hardware connection were found when scanning the address for this IC. What changes are necessary to set up the I2C EEPROM device? Note: I used 10k pull up for the I2C lines. H/W interface:

I'm using NANO 33 BLE SENSE. Could I ask if the magnetometer in LSM9DS1 uses AMR or Hall technology?

Inspired by a nice review by Jacob Beningo, I wanted to give it a try but failed right on the entry.Their web UI says my email is not confirmed and I have no clue how to confirm it. Received their "welcome" email, but no hints how to confirm the email address. Has anyone succeeded to log in and use it?I've sent a message to their support, no answer yet./* Just to save readers time, a brief explanation what embedd.it offers:It is 'yet another' AI coding assistant service targeted to bring up and make drivers for various devices and sensors, such as GPS, accelerometers etc. Currently it supports devices connected over i2C and SPI.As a host system, it supports bare-metal MCUs (including STM32's of course) and Zephyr boards.Users upload a data sheet PDF for their device(s).

Our company is currently reviewing medical device solutions for cerebral blood flow velocity measurement and embolism detection. We are at the proof-of-concept (POC) stage and have not yet planned a mass production roadmap.We have selected a TCD probe and plan to transmit pulse waves through the probe and analyze the received Doppler signals. While researching, we found detailed information in the attached datasheet for the STHV748S device and have some questions:Does the "Digital Input" port refer to the pulse wave input port?The HVP (High Voltage Positive) and HVM (High Voltage Negative) ports are specified as 0 to +90V and 0 to -90V, respectively. Does the chip generate these voltages internally, or must they be supplied externally?Is the LVOUT port the output port for the Doppler RX signal after switching?When interfacing with the TCD probe, there is only one connection port. How should HVP and HVM be connected in this case?Is this device designed only for single transducer use (1

I'm using cr95hf-vmd5t RFID reader, I will use NTAG 424 DNA tags with NDEF message.Does the cr95hf-vmd5t support NTAG 424 DNA?If yes, can I use authentication? 

In the datasheet for the STSPIN230, the pin description for SENSEU says "Sense output bridge U (must be connected to SENSEVW)."Is this a hard requirement? I would like to be able to sense both currents separately with separate resistors in order to Kirchhoff's law the third phase current.The application I'm looking at using the 230 for is a battery powered motor and I pretty much have to use FOC for several reasons. The STSPIN low power series all seem targeted for this application but none have all 6 PWM inputs and 3 phase current sensing.

"Hello, could you please tell me what component corresponds to the SMD code 'DUJ' on this diode? It appears to be manufactured by STMicroelectronics and is mounted near the 12V power input on a hard drive circuit board."

So I want to order a STM32F407VG. But I would love to know where they are being shipped from. Because I don't see any VAT being added to my order. I could not find the information anywhere.I live in europe so I just wanted to know where they ship their products from.Thank you.

 Hello,Years ago, I integrated the DFUSe DLLs (STDFU.dll, STDFUFiles.dll, STDFUPRT.dll, STTubeDevice30.dll) into my 32-bit .NET application to update firmware on my devices. Everything has been working perfectly and is still running smoothly.Now, I need to run my application as 64-bit, but unfortunately, the DFU DLLs are only available in 32-bit.I was able to obtain the DFUSe C++ project and successfully recompile it in 32-bit. However, when attempting a 64-bit build, I encountered multiple errors. Since I’m not very experienced with C++ (I mainly work with C# in Visual Studio and C with STM32CubeIDE), I couldn’t resolve the issues on my own.I’m looking for a way to obtain these DLLs compiled for 64-bit:STDFU.dllSTDFUFiles.dllSTDFUPRT.dllSTTubeDevice30.dllI understand DFUSe is considered obsolete, but this update method fits perfectly with my systems, which are fully based on it. I would prefer not to change anything in the infrastructure—just to have the DLLs compiled for 64-bit.

Hello,I’m working on interfacing the Bosch BME688 sensor with my STM32 Nucleo-F446ZE development board using the BSEC library. The sensor is correctly providing temperature, pressure, humidity, and gas resistance data. However, I’m facing an issue when trying to calculate the IAQ (Indoor Air Quality).The function bsec_do_steps() returns the following errors during debugging:BSEC_E_DOSTEPS_VALUELIMITSBSEC_I_DOSTEPS_NOOUTPUTSRETURNABLEHere’s what I’ve done so far:Initialized the BME688 and configured it in forced mode using settings from bsec_sensor_control().Populated the bsec_input_t array with sensor data and called bsec_do_steps().Verified that timestamps and sensor signals are correctly passed.Despite this, IAQ outputs are not generated. I suspect the issue might be related to input data limits or incorrect configuration, but I’m not sure how to resolve it.Has anyone encountered similar errors or could provide guidance on resolving these issues?Any help would be greatly appreciated!

Hello everyone,Does anyone happen to know the exact equivalent for the part number "G23"? I've been researching it, but I'm not entirely sure whether this code matches the Schottky rectifier STPS2L25. Maybe someone has used it before or is familiar with it more precisely.Thanks a lot—appreciate it!Best regards.

Dear community,We are currently developing a system based on the ST7580 FSK modem, designed to communicate over a shared power and data line. The architecture consists of a Master device communicating with more than 100 Slaves over a single pair of wires, used simultaneously for 24V DC power delivery and FSK communication.Our objective is to support communication over distances of up to 10 km in a free topology (e.g. star, tree, or mixed). We're sharing the schematics of the Master and Slave power supply and ST7580 interface circuits, and would appreciate your feedback on key design decisions and areas that may benefit from improvement.System OverviewModulation: FSK using 120 kHz and 84 kHz, with a deviation factor of 1.Power Supply: ST7580 is powered at 12V.Transmission Gain: Increasing the TX_GAIN parameter has proven effective at raising the signal amplitude beyond VCC, although some waveform distortion is observed.Design Goal: Achieve reliable communication with a high number of no

hello people! thanks for coming to help me. I'm having problem in debugging a code which is written in bare metal programming. the concept of the program is that it uses the inbuilt led and temperature sensor. the led blinks according to the adc value of the temperature sensor. But the led is constantly on instead of blinking. i tried a simple led blinking code it worked fine but this temp code its making the led to be constantly ON I dont know what the problem is . i will give the code i wrote below plz help me #include<stdint.h> #include<stdio.h> //registers used volatile uint32_t *RCC_APB2ENR =(volatile uint32_t *)0x40021018; volatile uint32_t *GPIOx_CRH =(volatile uint32_t *)0x40011004; volatile uint32_t *GPIOx_ODR =(volatile uint32_t *)0x4001100C; volatile uint32_t *ADC_SQR3 =(volatile uint32_t *)0x40012434; volatile uint32_t *ADC_SMPR1 =(volatile uint32_t *)0x4001240C; volatile uint32_t *ADC_CR2 =(volatile uint32_t *)0x40012408; volatile uint32_t *ADC_SR =(volat

hiI'm using an STM32F103C8T6 (Blue Pill) with a SEGGER J-Link for programming and debugging. I attempted to enable SWV for runtime variable monitoring by connecting PB3 (SWO) to the J-Link SWO pin, but it didn't work.Is there any way to use SWV without relying on Serial-to-USB (USART) on this MCU? Any guidance would be appreciated.

Hi,I’m working on designing a custom board for industrial applications and would like to use the crystal X53T-C20SSA-25.000MHz, which is used in the STM32H7xxI-EVAL board for the LAN8742Ai PHY. However, I can’t find this crystal available anywhere. My questions are:What is the best replacement for industrial use?What capacitor values should be used if the crystal is changed?Additionally, is the ABM8W-25.0000MHZ-8-D1X-T3 a suitable replacement? If so, what capacitor values should be used? Thanks,Mohammed
