Hello,   I am using STM32L073RBT6 controller. I want to use standby mode in my battery operated instrument. I want to use single tactile button to enter and exit standby mode. Is it possible to do??  What if I allocate another nearby pin as GPIO interrupt and short it to SYSTEM_WAKEUP pin and use it to enter in the standby mode? Thank you so much in advance for the help.  Have a great day ahead!

I am using STM32s NUCLEO-H755ZIQ board , while debugging through eclipse IDE for the M7 core the board's MCU went under low power state and LD6 which is over current led (red) is turned on.When I am connecting the board with the STM32CubeProgrammer the board is gettting detected but ST-Link is failing to flash the board.  Please help me with this problem as same thing has happend with the another NUCLEO-H755ZIQ board.Both the boards are having same problem

Hi Sir,I am reviewing the application schematic of the STUSB1600 in a dual-role Type-C design. I understand that when STUSB1600 operates as a Source, the output current can be configured through the CC_CAPABILITY_CTRL register.However, I did not see an explicit current limiting component in the provided schematic. I would like to ask whether ST has any recommended external circuit solutions to further enforce current limitation, such as a preferred power switch or current limiting IC that is compatible with this setup.Additionally, I would like to confirm: if we only configure the CC_CAPABILITY_CTRL register without any external current limiting components, would the actual output current still exceed the configured 1.5A limit in certain conditions? If so, could you provide a reference circuit diagram or recommendations for suitable current limiting components that ensure proper current regulation?    

Hi, how to read the date code marking on M41T62LC6F. Example attached: 231C4 Thanks,   

Can I find the manufacture year from the bulk ID? Most of ST parts only indicate the last digit of the year, sometimes we just don't know it is 2013 or 2023. 

I could really need some help how to get a STM32F030T4P6 to act as a i2c slave and receive a byte of data I've spend so much time in the past week trying to solve this problem, but no progress at all The final code must act as four PCF8574 port expanders and save the received byte in a common array with one index for each of the four PCF8574 addresses. Why?.... Because it is a very easy way of getting some data from Home Assistant, via EsPHome into the MCU for further usage I need to use these 4 bytes to create some serial pulse trains thet will control some relay modules that is using a special protocol. I created a simulator to generate the I2C traffic, and it sends a write to the 4 I2C addresses with a delay of 2 seconds between packages, and then sends a read to the same 4 i2c adresses every 2 seconds, and then it starts over again Currently my code only listen on one I2C address 0x20, and I can see, with a logic analyzer, that the STM32 sends ack both after an read and a write fro

Hey All,we are not able to use the latest STM32CubeIDE 1.13.x IDE as the myST login doesn't appear (just the blue animated loading animation).In our other Eclipse-based applications we just imported our certificates using the keytool into the Java certificate store. For eclipse this seems to work as downloading stuff from the marketplace works just fine.But this one seems to be ignored by the properitary login mechanism.Any ideas how to solve this issue or debugging it further?Thank you!

i have STM32103RBT6, i want to use all three UARTs for a project. i want to use UART2 thorugh PA2 and PA3. The connection are : SB61, SB62 and SB63 are open. SB13 & SB14 are open as well. Continuity is there between SB62 & SB62 to TX on ST link (from track side) & between SB63 to RX on ST link (from track side). No continuity between  PA2 and PA3 with SB13 & SB14. can anyone tell me how to use UART2 from the PA2 and PA3? i want to use it for modbus but the transmission is failing. 

Hello.An inexplicable bug occurs during the transition from startup_stm32h743xx.s to main, causing unnecessary functions to be repeatedly executed.An unknown function (I2C_IsErrorOccurred) continues to be called. It is strange that it is being invoked despite no initialization being performed. I believe that fixing this bug requires identifying the cause of the repeated calls to an unknown address, but I lack sufficient knowledge to do soI need the help of someone knowledgeable.IDE:μVision V5.40.0.0Toolchain: MDK Plus 5.40 : 5.40.0.3C Compiler: ArmClang.exe V6.22Assembler: Armasm.exe V6.22Linker/Locator: ArmLink.exe V6.22Library Manager: ArmAr.exe V6.22Hex Converter: FromElf.exe V6.22CPU DLL: SARMCM3.DLL V5.40.0.3Dialog DLL: TCM.DLL V1.56.4.0Target DLL: ULP2CM3.DLL V2.215.24.0Dialog DLL: TCM.DLL V1.56.4.0 I haven't made any particular changes to the linker, startup, or system initialization, and I am using the default address 0x80000000.

 Hello everyone,I am very new to the STM ecosystem and don’t know much about it. I am using an Ubuntu PC and trying to work with the X-NUCLEO-53L8A1 expansion board and NUCLEO-F401RE.There is a software package available for VL53L8CX to detect the presence of someone: "https://www.st.com/en/embedded-software/stsw-img042.html". I downloaded it along with the Linaro GCC toolchain from Linaro Releases. After running the Makefile and trying to start the application, I encountered the following error: "./spdkit: 1: Syntax error: Unterminated quoted string".  At first, I thought this was a command-line issue, but I suspect something else is wrong. Since the X-NUCLEO-53L8A1 communicates via I2C, I checked for available devices with: "sudo i2cdetect -y1".However, no I2C devices were detected. I also noticed that my NUCLEO board is recognized in ST-Link mode, which might be preventing proper I2C communication(i am not sure !)I’m a bit lost and not sure where to start troubleshooting.

Hi everyone,I'm working on a project with STM32CubeIDE and an STM32H747 microcontroller. I've configured the clock sources in the .ioc file as follows:High Speed Clock (HSE): BYPASS Clock SourceLow Speed Clock (LSE): Crystal/Ceramic Resonator  When I generate the code, the process appears to complete successfully, as I don't receive any error messages. However, when I check the SystemClock_Config function, I don't see the clock configurations that I set. Here is the generated code: void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; /** Supply configuration update enable */ HAL_PWREx_ConfigSupply(PWR_SMPS_2V5_SUPPLIES_LDO); /** Configure the main internal regulator output voltage */ __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE1); while(!__HAL_PWR_GET_FLAG(PWR_FLAG_VOSRDY)) {} /** Initializes the RCC Oscillators according to the specified parameters * in the RCC_OscInitTypeDe

Hello Community,I am trying to build a 333V Battery Pack with AEK-MCU-C4MLIT1 as the Master, AEK-ISOSPI Translator and multiple AEK-POW-BMS69EN as slaves in daisy chain configuration. I would like to get the information such as cell voltages, SOC, and Balancing commands from the slave and send it onto the Vehicle CAN Network.As of now, I have been able to get the cell voltages on the serial terminal from one 48V dummy pack which I have built. And, I have been able to send some dummy data from the AEK-MCU-C4MLIT1 Master CAN 1 Channel and read it with the help of a CAN KVASER Dongle.Now, When I went for combining these two functionality the project didn't seem to work. I suspect that maybe the pins which I am using to establish the ISOSPI communication between the Master and the Slave are interfering when I am trying to establish the CAN Communication. But, I tried configuring the pins on the CAN0 channel (Pin 101 as RX and Pin 102 as TX) but I am not seeing anything on the CAN_1_L

I have been trying to find a way to increase the icon size for the STM32CubeIDE toolbar. Today I found a way that worked for me.  

Hello, I'm working on a project based on NUCLEO-WB55.USBDongle. According to Zigbee specification paragraph 3.6.1.2 referring to to the NLME-PERMIT-JOINING.request procedure:When this procedure is initiated with the PermitDuration parameter set to a value between 0x01 and 0xfe, the NLME shall set the macAssociationPermit PIB attribute in the MAC sub-layer to TRUE. The NLME shall then start a timer to expire after the specified duration. On expiration of this timer, the NLME shall set the macAssociation-Permit PIB attribute in the MAC sub-layer to FALSEWhen this procedure is initiated with the PermitDuration parameter set to 0xff, the NLME shall set the macAssociationPermit PIB attribute in the MAC sub-layer to TRUE for an unlimited amount of time, unless another NLME-PERMIT-JOINING.request primitive is issued.I implemented the following code on coordinator to update the join permit: struct ZbZdoPermitJoinReqT req; memset(&req, 0, sizeof(req)); req.destAddr = ZB_NWK_ADD

Heyho,I'm currently using a GPIO on a STM32L031 for a custom 1-wire interface, which means it's switching all the time between input and output mode (open drain).So far I have learned that the EXTI interrupt only works with GPIOs in input mode.My question:Once I have enabled the EXTI for a certain GPIO in input mode, then change the GPIO mode to output, then back to input, do I have to re-enable the EXTI somehow, or is it still working as before?Thanks in advance!

Please could I have help identifying the component in the attached image to find a suitable replacement as it is shorted.I believe it's a TVS as it is placed between A +24V output and GND. I am unable to find the specific part number though. Many thanks, Jazz. 

I am using STM32H747I-DISCO board, and this is the selected board in TouchGFX Designer.I created the Tutorial 3 Applications with multiple Screens in TouchGFX Designer called DigitalClock app. I added Clock displays and UP/DOWN arrows with its virtual functions. The app works fine in Simulator, hours and minutes can be set to any value between 0-23 and 0-59 range. Overflows are handled right.Even the DigitalClock runs fine in Visual Studio 2022 (C:\TouchGFXProjects\DigitalClock\CM7\TouchGFX\simulator\msvs\Application.sln). I can set breakpoints, check value of display buffers. It is amazing job guys. Congrats!The problem begins when I connect the STM32H747I-DISCO board to my PC and I click Program and Run Target in TouchGFX Designer. It fails with a funny "No such file or directory" as the first error (There are other errors and all are related to generating fonts. The first error is arm-none-eabi-g++: error: CM7/TouchGFX/generated/fonts/src/Font_verdana_20_4bpp_0.cpp: No such fil

Hello everyone,For a personal motion recognition project using artificial intelligence and NanoEdge AI, I am looking to purchase components. I am hesitating between two architectures and would like to know if both are viable options and, if so, which one is the best and what the differences are.The first option: STEVAL-MKI109D with STEVAL-MKI229AThe second option: STEVAL-MKI233KA + STEVAL-MKIGIBV5 + STEVAL-MKI109V3 or STEVAL-MKI109DThank you in advance for your feedback!

Hi,I am working on stm32h747i-Disco board, I was in using FP-VISION (person detection) for the ai model to work on my board.And that's fine, it works well but now i need to connect and esp01 or Pico W with UART or with SPI.i just modified the code to do so but it did not worked, I just tested my code with another file and the code worked well. so can you clear me whether  the UART or SPI is connectable or not when the FP-VISION is running ?(i used UART8 or SPI5,And i mainly in UART code when i initialize the uart8 it stops with the menu display which usually comes when started)
