HiI have an application that uses an STM32F105RBT6 ant its USB peripheral as host mode connected to a HID controller, and driving a few GPIOs connected to 74HC04 inputs.The application was created using firmware package 1.7.0 and STM32CubeMx with a Makefile and linux toolchain.The application has been enhanced on a F205 board with STM32CubeIDE, where it is working well, and the enhancements are being backported to the F105 with 1.8.4 firmware package. I write "backported" however it is mostly the same code, but the pinouts are different.There, I have a strange behavior :PB3, pin 55 on the package, which is a simple Push-pull GPIO output, does not work on the updated app with 1.8.x firmware with the F105 board. What is strange is that on the scope it is stuck flat to a 0.3v level, which is slightly higher than the other outputs at their low level : as if the pin was not set like the others.The outputs are set just with the generated HAL configuration and HAL WritePin inside the USBH pro

I have examples but they do not use the .ioc file. I need to find a way to integrate the drivers using the ioc file.

In the STM32CubeMX there is a preload setting. If I enable the preload then I can see the update interrupts are working as expected. But, if the preload setting is set to disabled, then no update interrupts are seen. This is true for all timers A-F and also Master timer.NOTE: Only the update interrupt is impacted here, while other interrupts are working fine.

Hi,I finally got my zigbee up and running on v.13.xx but it stops working, properly in M0 core after 5-20seconds.However I thought it would be good to go to 14.1, so i did, made a project.But i cannot compile the project.It is based on Cube...I get this error:Why do it not find it, there is some references in the code, but it may be library missing or?Please adviceThanksKasperc:\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\ld.exe: ./Middlewares/ST/STM32_WPAN/zigbee/core/src/zigbee_core_wb.o: in function `Zigbee_CallBackProcessing':C:/Users/8/STM32CubeIDE/workspace_1.6.1/Zigbee_1_4_start/Debug/../Middlewares/ST/STM32_WPAN/zigbee/core/src/zigbee_core_wb.c:3800: undefined reference to `zcl_cluster_data_ind'c:\st\stm32cubeide_1.6.1\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.10.3-2021.10.win32_1.0.0.202111181127\tools\arm-none-eabi\bin\l

I looked through the datasheet looking for a section that details what markings I can expect to see on an STBB1-A regulator IC, but I couldn't find anything. I imagine it will just be an abbreviation and a date code and/or factory location, but I'd like to know for certain. Perhaps it is in a separate document??

I noticed a problem (possible BUG) with the Clean Project when working with bigger projects in STM32CubeIDE 1.7. When I try to clean project i get error: make -j12 clean  make (e=206): The filename or extension is too long. make: [makefile:169: clean] Error 206 (ignored)I tried to build and clean the same project with STM32CubeIDE 1.6.1. In this version everything worked fine.To reproduce this issue one can try to build and clean TouchGFX Demonstration for STM32H753G-DK board in CubeIDE version 1.7.0 (STM32Cube_FW_H7_V1.9.0\Projects\STM32H735G-DK\Demonstrations\TouchGFX\)

I follow the example of NUCLEO-H723ZG. all the setup same as I done why Iget these error ? can you please help me

Hi, I used a swipe container with 2 pages, and I want to drag the icon from the 1st page to the 2nd page. But the icon cannot move to 2nd page because the icon is create in the 1st page container and doesn't move across container. How can achieve my needs ?

Hi, may i know how to open the serial monitor on UDE STK ?i have been search whole day to monitor my adc value but i didn't found the serial monitor. 

As per application note, it says X-CUBE-LPUART supports STM32U5. I am trying to find example for LPUART Reception in LPBAM but I am not able to find any example. Cube IDE has one example but LPBAM mode configured only for transmission. For the reception it is not even initializing LPBAM application. LPBAM itself is very complicated design. No proper documentation on it.

Hi,I'm trying to set the RTC date and time when uploading my code to a NUCLEO-L476RG board. I've already configured the RTC in CubeMX, and it works as it should. But I've only managed to set the time manually by setting the BCD values for Hours, Minutes, Seconds and so on in CubeMX when configuring the RTC (or changing them directly in the RTC init function). So I would like to know if there is a way to read the current wall clock time from the PC and use this to set the RTC. I've tried including time.h and using time(NULL) to read the wall clock time, but it returns -1 (which according to the docs means calendar time is not available). Do I need to configure the GCC toolchain to be able to use time.h, or is there another way to read wall clock time onto the NUCLEO board?Any help is much appreciated.

Hi, I'm using STM32H7A3, and I’m a bit confused about injected current for pins used as analog input. In our design, I used both 5V tolerant and 3V tolerant pins as analog input. And VDD=3.3V, VDDA is connected to VDD with a bead. And Vref is 3V. And for each input, I have clampon diode connected to VDD, not Vref. For 5V tolerant pins, positive inject current would happen when Vin > min(Vdd, Vdda)+3.6V, with maximum 5 V. For 3V tolerant pins, positive inject current would happen when Vin > Vdd+0.3V In the document here, chapter 5.2.1 and 5.2.2 https://www.st.com/resource/en/application_note/an4899-stm32-microcontroller-gpio-hardware-settings-and-lowpower-consumption-stmicroelectronics.pdfIf the pins are used as analog input, the maximum operating voltage on pin cannot exceed min(VDDA, VREF+) + 0.3 V. Does it mean injection current will happen when VIN > min(VDDA, VREF+) + 0.3 V, or the injection current will happen only when VIN > VDD?

According to UM2237, the Connect command in the CLI (command line interface) supports SPI, but what is the device used to connect the Nucleo board to the PC? How does the device look like from the PC side (device manager)?---> start (added to question on 10/09/2021)I purchased the STLINK-V3SET and tried it with the STM32CubeProgrammer, but I cannot establish a connection with the device via SPI.The board I am using is NUCLEO-L4R5ZI, and the following are the pins that are connected to it:(1) STLINK, CN5, Pin#1(SPI_NSS) to NUCLEO, CN12, Pin#16(PB12, NSS)(2) STLINK, CN5, Pin#3(SPI_MOSI) to NUCLEO, CN12, Pin#26(PB15, MOSI)(3) STLINK, CN5, Pin#5(SPI_MISO) to NUCLEO, CN12, Pin#28(PB14, MISO)(4) STLINK, CN5, Pin#7(SPI_SCK) to NUCLEO, CN12, Pin#30(PB13, SCK)(5) NUCLEO, CN11, Pin#5(VDD) to NUCLEO CN11, Pin#7(PH3-BOOT0)I operated as follows:(a) Press RESET button on NUCLEO to start STM32 Bootloader(b) Select SPI as Port in STM32CubeProgrammer and press Connect button(c) Failed to establish c

Hello,I have not been able to program the MCU from ST-Link/V2 (Serial 2-wire) - I suppose this is possible??Bonus info: Debugging with J-link and same (serial 2-wire) works fine.Thanks in advance - Michael

I'm new to Cube IDE and Cube MX but I've been trying to create a simple project based on an STM32H753ZI to investigate ADC capture.Having enabled a few channels on ADC3 I looked in the clock tree to find the ADC clock speed but it's greyed out. When I hover over the ADC Clock Mux section I get a message saying "ADC Clock Source is not available" and to configure one in the Pinout Tab ADC.I can't see any options that mention anything to do with a clock in the ADC section (or , I've seen screenshots from the STM32H743 where there is a "Clock Prescaler" option under ADC_Settings, but I don't see this option in my case. I've seen that sometimes options only become visible when other options have first been set, so hopefully this is something simple that I've overlooked.Any help would be welcomed.

I have both these devices on the same I2C bus and am trying to calculate the maximum pullup resistance.Thanks!

I'm using an STM32L4 with STM32CubeIDE, bare metal, and using C++ along with Cube's C libraries. The compiler is the GCC/G++ supplied with STM32CubeIDE.I have some dynamic memory usage in STL containers etc. I'm aware of the recommendation not to use dynamic memory on bare-metal embedded systems, but it is generally used only during initialization, minimizing the complications.I would like to know how much of the heap I'm using, and found no way to do that. I saw discussions of __heapstats but it doesn't seem to be defined in this toolchain (?).It doesn't have to be a programmatic way, if there is some internal data structure of newlib or whatever that I can watch while debugging that will suffice.p.s.I know the term "free heap space" is not very well defined, because of block sizes and fragmentation, but I suspect that in my case it's going to be one big free block.any ideas?

Hi,I'm struggling to add low-power features to my device application, hopefully I can get some help here.What do I want?My device is sampling sensor data (52Hz) and saving it periodically to external flash memory. When the device is running in sampling mode I do not want to do anything with Bluetooth (CPU2). If possible I want to have it fully disabled!What have I tried?Read the Low Power manager description in this manual.Add the following to my application:• Create a user Id (CFG_LPM_Id_t) in app_conf.h • Call UTIL_LPM_SetOffMode() • Call void UTIL_LPM_EnterLowPower()ResultThis will indeed significantly decrease my power consumption, but it looks like CPU1 is set to OFF as well. My sensor processing stops as well as my interrupt triggers (DRDY) coming from a MEMS sensor. Similar behavior I have with UTIL_LPM_SetStopMode().Is there any way to have CPU2 power consumption to a minimum, independently from CPU1, which should sample data and input it to an AI model (so I guess it's not pos

I have a script in my project that generates code prior to a build that works great. However, I'm trying to set up command line builds and I'm getting an error when I build from the command line:Contains: Variable references empty selection: ${project_loc}I tried to set this variable in the shell prior to building but no luck.I can probably work around this in one of two ways:Hard code the path to the project (but this may break build on other machines)Disable the script and call it on the command line (but this break the build in the IDE)Command line:/opt/st/stm32cubeide_1.4.0/stm32cubeide --launcher.suppressErrors -nosplash -application org.eclipse.cdt.managedbuilder.core.headlessbuild -cleanBuild my_project/Release -data ~/stm32/workspace -D CMD_LINE_VARIf anyone has any suggestions that would be great.Builder setup:Project -> Properties -> Builders -> Main

Hello everyone,I am currently working on the hardware design of a STM32WB55 and there is an information I would like to clarify.In the AN5165, it is explained that the RF track should be matched at 50 ohms. However, on page 43/48 - figure 36, there is an extraction of results with a test bench used by ST showing the optimal impedance for TX, which is a bit different than the 50 ohms specified (result is Zopt,TX = 42 - j19).Which impedance should I target for my application ?Regards.
