I have this board (revision C-04) with ST-LINK removed (PCB cut off), so the power 3V3 is supplied from CN7. It works fine, but the red power led (LD3) also works. LD3 is, I think, connected to the 5V net, and 5V to 3V3 regulator should not be working but then why the LD3 is shining red?

Hi folks, first off all I'd say to that I'm really new to MCU and for some silly reason I went for a STM32F7508-DK as my first board of STM3. With that being said, I'm asking for help on why my Led blinking code is not working,/* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * <h2><center>© Copyright (c) 2021 STMicroelectronics. * All rights reserved.</center></h2> * * This software component is licensed by ST under Ultimate Liberty license * SLA0044, the "License"; You may not use this file except in compliance with * the License.

(apologies for posting twice, i posted in another STM community by mistake and someone provided an answer: https://community.st.com/t5/other-software/mcu-gcc-path/m-p/570320)HelloI am trying to save memory by keeping the system headers (paths are shown in the diagram) and drivers in one folder, and modify the paths in the projects to point to that folder.I need to modify many of the paths in the "project/c++/mcu gcc". Is there a way to export/import the paths to a file?Or are the paths already stored in a file so that i can edit that file directly ?thanks

Hello,I need a quick confirmation. Assuming I have correctly provisioned OEM1KEY and OEM2KEY and I don't use OTP memory, I will always be able to revert my STM32U585 chip from RDP level 2 to blank state (RDP level 0, erased Flash, TrustZone disabled) and then be able to program again a brend new firmware.Is that right?

My company just purchased 10x new STLINKS in WINSOURCE.We are having trouble using them with newer versions of STCubeProgrammer(v.2.10.0),they work fine with the old STlinkUtility.I am also unable to upgrade the Fake STlink: The BOX seems legit:  The plastic molding looks alright also, the back sticker is upside down. Once i open the new stlink, i notice the mcu markings are erased.

What are the units of the ISM330DLC reported values? SpecificallyOUTn_G to units of acceleration (g)?OUTn_XL to units of angular velocity (°/s)?I couldn't find this in your docs, may have missed it 

Hi to all. I have a problem whit USB dongle STM32WB55.With BLE stack and all BLE examples from STM32Cube_FW_WB_V1.16.0 Virtual USB port is working just fine. But when I change to stm32wb5x_Zigbee_FFD_fw and use P-NUCLEO-WB55.USBDongle\Applications\Zigbee\Zigbee_OnOff_Server_Coord Virtual USB port is not working (error code 10). I can turn on and off LED form coordinator (dongle) to router (Nucleo board), and virtual port on Nucleo is working just fine. But virtual port on dongle is not working (erorr code 10).My OS is Win10, I updated Virtual serial port drivers, I changed CDC_DATA_HS_MAX_PACKET_SIZE to 64U but again I have the same problem.Can you please help me.Thanks.

Hello, when will the Functional Safety Manual for the STM32H5 be available?

Hi all,I am using the software generated from MCSDK motor control and a custom board, I am able to successfully make it work for the torque control mode, for different Iq values the DC power supply current is varying.But i am facing problem with speed control mode, i gave the following command in closed loopMC_ProgramSpeedRampMotor1(((int16_t)g_targetspeed_s16 * ((int16_t)SPEED_UNIT)) / (int16_t)U_RPM, 0);Any value i give for g_targetspeed_s16 the motor settles to the same speed for example if i give 10, 50 it goes and settles to the same speed. Why? I am finding some invalid switching. Is it because of that?

Hi STM,I am having NUCLEO-476RG and I am planning project with steppers (by using X-NUCLEO-IHM01A1). Can I connect this expansion with my development board. And also, what is the maximum number of expansion boards I can connect to the development board. I am asking that as my project should use 7 motors?Regards,Aleksandar

This page was opened using a "permalink" to an individual post, which apparently has its own title, although that is never displayed in the posts view of the thread. The title used in html's head (thus browser's tab/bubble/whatever) and also breadcrumbs comes from that post, confusingly different from the threads title/subject.Just don't do that, don't allow titles/subjects to individual posts, discard them, they are not needed and confusing.JW

Hi,I'm following the LoRaWAN with STM32 Getting Started series on youtube and stuck with Part 6 - Low power modes. I need to change the "DEFAULT_TX_POWER" to TX_POWER_11 to work with the X-NUCLEO-LPM01A Shield.I'm unable to make any changes to the region.h files in STM32Cube-fw-wl-v1.3.0. (Or any of the header files found in Middlewares/Third_Party). Is this normal and I just have to create new head files or am I missing something?Kind regards, Oliver

In Bookmarks, first 5 chapters are repeated: The same was with 'L4 manuals, lazy to look up the thread, I wonder whether those are fixed [EDIT] found it https://community.st.com/t5/stm32-mcu-products/rm0351-repeating-bookmarks/m-p/120032 [/EDIT]JW

HiI need to modify many of the paths in the "project/c++/mcu gcc path". Is there a way to export/import the paths.Or are the paths in stored in a file so that i can edit that file directly ?I am trying to avoid to modify the paths one by one.The objective is to keep all the system headers and middleware in a folder that all other projects can access to save memory. And I need to modify the paths in the projects to locate those system headers. thanks

We need Android SDK for STSW-ST95HF001. Kernel is 4.9. Android is 10.Any documentation would be great too.Thanks in advance.

I have purchased STM32F411RE & Nucleo-GFX01M2.I attempted to complete one of the examples in “ TouchGFX ” but there is no option for the board.The “ TouchGFX 4.22” does not have the above board.Is there a tutorial on adding the board to the list or is it a “ST Microelectronics” only function

I'm working on my project with L432KC which can support only I2C. I need MCU board which is supporting I3C communication.

Does the STM32L100RC have a temperature sensor?RM0038 refers to the temperature sensor in the STM32L1 line of processors. However, the STM32L100RC datasheet only mentions "tempsensor" in table 4 and nothing else anywhere. CubeIDE will allow the temperature sensor ADC channel to be selected but apparently no code is generated. There's a macro in stm32l1xx_ll_adc.h , __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS(), for converting the value to celsius but it requires parameters from the datasheet that don't exist: avg_slope and V110. These parameters exist in other datasheets, however. The comment near the macro sure seems to imply that the processor has the sensor, just not the cal constants: /* Note: On device STM32L100, calibration parameters TS_CAL1 and TS_CAL2 are not available. */ /* Therefore, helper macro __LL_ADC_CALC_TEMPERATURE() is not available.*/ /* Use helper macro @ref __LL_ADC_CALC_TEMPERATURE_TYP_PARAMS(). */ /* * __TEMPSENSOR_TYP_AVGSLOPE__ Device datasheet data: Tem

There is "96-bit unique ID" in the datasheet (DS13514 Rev 2 ). The feature is also listed on product page . But there is no mention of unique ID in the reference manual (RM0454 Rev 5). Does the MCU have unique ID and how it can be accessed?

Hi, We want to incorporate the STLink firmware binary provided by STMicroelectronics here onto our custom STM32 board with stlink circuit. However, we would like to seek clarification on whether this usage would allow us to sell our custom board commercially.We kindly request your assistance in understanding the implications of the license agreement when binary is distributed via inside the chip and any potential limitations or permissions for commercial usage of STLink firmware on a custom board. Thanks

I have some re-used and portable code that uses <assert.h> and assert().Is there a way I can easily map assert() to the assert_param() used by CubeMX?Seems so simple but it is giving me a hard time, and I don't see anything available online about this.

This is weird.  Also it was working at one point and stopped working, can't track down the code change that broke this. So, I use HAL_UART_Receive_DMA() to start a DMA RX.  I can use _HAL_DMA_GET_COUNTER() to check how many characters have been received and I am receiving characters, but the contents of the buffer I passed to HAL_UART_Receive_DMA() is not changing.  Why would the DMA counter increase but not the memory buffer contents?  I checked the hdmarx handle in the UART handle, the Instance pointer in the hdamarx handle, and the MOAR and PAR pointers in the DMA peripheral - everything looks correct. What more can I do to try to diagnose this problem? Normal DMA (not circular), Peripheral to Memory.  Interrupt should be enabled but I don't think I need it with checking the buffer contents as it's received. I got the idea to poll DMA contents while receiving from this blog post:https://blog.stratifylabs.dev/device/2021-12-30-UA
