Hi,I am wondering about an apparent discrepancy in documentation of the pin outs for the Nucleo-H743ZI2 board:The "user manual" for the Nucleo-144 boards, on page 7 has in a footnote that H743ZI has been replaced by the H743ZI2. (Link: https://www.st.com/resource/en/user_manual/dm00244518-stm32-nucleo144-boards-mb1137-stmicroelectronics.pdf)In the same manual, the extension pin outs for H743ZI are given on page 32. It is not made clear in this document that the pins outs have actually changed. How do I know this? Because, on purchasing a Nucleo-144 STM32H743 board (with the H743ZI2) I see different extension pin connections for connector 7 (e.g. CN7 - pin 12) specifically. Why has the documentation not been updated to reflect this? Maybe I'm looking at the wrong user manual? Maybe the documentation needs updating to stop people wasting time trying to figure out why things don't work as they should. Best regards,Nat

I loaded my mobilenetv3 model in STM32CubeAI but when I tried to choose the compression ratio of 4 and 8 to reduce size, the RAM and FLASH requirements are still the same.Also, I optimized my model in tensorflow lite which results in ~2MB, but when I load it into STM32CubeAI, it still reads the original size which is 6MB?Please help.

Hello,I am using slideMenu widget and it works fine. Now I am trying to open this widget by a gesture. Normally I would override gestureEventCallback in my View- and actually I did it but it does not work well. I have two slide menus on top and on the left and if I slide from the left to right at 30o angle I get 2 gestures- HORIZONTAL and VERTICAL, always in the same order therefore it is impossible for me to detect if I should open top or left menu.I came to idea that I can first check the click event for pressed, save the coordinates, wait for gesture event and then wait for released click event- in that combination I am able to get all data to find out if I should open top or left menu. But If I override click event in my view I can not trigger buttons which are present in the view.So my question is- is it possible to, after I trigger view's clickEventHandler pass the event further to trigger next widget in the area where the click occured? Is TouchGFX capable of doing that?

Hi everyone,Thanks in advance for your time.Im starting my first application in ST: a power converter controller. I need to be able to control two three-phase inverters with SPWM modulation, for which I think STM32H743 is the microcontroller I need. It has (as many others) advanced control timers TIM1 and TIM8, but I have a doubt about them:Can each of them generate THREE PWM signals phase-shifted 120º modulated by SPWM, PLUS THREE complementary, for a total of 6? (For example, TIM1_CH1, TIM1_CH1N, TIM2_CH2, TIM1_CH2N, TIM1_CH3, TIM1_CH3N). And same with TIM8 for another 6?As far as I understood, each timer can only generate ONE pulsed signal in all of its channels AND its complementary on its CHX_N channels.Any help, contact or guide will be appreciated since I'm a M.Sc. Student and this is for my master thesis.Thank you!

HiI'm using IAR EW for ARM.I would like to get a simple working project that is made for the STM32F767ZI processor, preferably running on a Nucleo-144 board.The example should only make the initialisation of the processor. I'm making a Bootloader so I don't think I need much more. I'm just worried with putting the Processor clock working.I'll be using FreeRTOS IP stack but for now I only need the processor starting.In there any Wizard for IAR that creates a simple example project running on the Nucleo-144?thanks

Hi everyone,I'm designing my first STM32 design using STM32F103C8and wondering if I can use 2 Ceramic resonators instead of oscillators as shown in my schematic.thanks in advanced!Tommy

I captured it when the device asked for the update but the file may have gotten corrupted. Loaded v3.41 using STLinkv2 and the sensortilebox now appears to be dead. The file I have is 726691 bytes and doesn't appear to work. Sensortile won't boot, no LEDs.thanks,tjm

I'm using a IIS328DQ on I2C buss (400KHz). I've got it set up at +-4g 100Hz samplingIt looks like it's doing it's thing correctly BUT for the z axis value. After the interrupt for data, I'm reading the XYZ outputs (MSB first order) and getting00 50 FE 90 21 10 With the thing sitting mostly flat. X and Y are plausible but Z is 0x2110 meaning that it's like numbers in the 8464 range or 15 bits FS. The datasheet isn't all that clear about how many bits this is, but I'm thinking this is supposed to be +- 11 bits (12 bits signed) FS. This number doesn't agree with the datasheet whereas the X and Y numbers are showing FS to be 11 bits (2048) at 1.05mg/bit correctly...What could this possibly be? Id' expect a solding problem to give me warped X and Y maybe but not Z at 4X what full scale is supposed to be....

Hi all,I read STM32F4 MCU family doesn't support SMBus because of hardware limitations in the I2C cell. For this reason SMBus is not included in the HAL driver. If I choose STM32F439ZI in STM32CubeMX and I activate I2C, I can select between 3 different modes, as shown in the picture below. So I'm very confused. Does STM32F4 family support or not SMBus? Is there STM32F4 family SMBus HAL Driver? Thank youBest regards,Antonio 

Hello,Doing a "git diff" on my project IOC file notably highlights these changes:-Mcu.Pin6=PA2-Mcu.Pin7=PA3+Mcu.Pin6=PA0+Mcu.Pin7=PA1Looking at the IOC file, I do not think that these Mcu.PinXXX parameters define the actual pin name associated with a physical pin number.So I am wondering what these Mcu.PinXXX parameters represent. And an even more important question: where are all STM32CubeMX IOC file parameters documented by ST? Googling them leads to no results.Thanks!

Hi All, I created a test project to Wake Up the device from STOP Mode when it receives data over UART. I ported code from "UART_WakeUpFromStopUsingFIFO" available at /STM32Cube/Repository/STM32Cube_FW_L5_V1.3.1/Projects/STM32L562E-DK/Examples/UART/Example project from STM is working as expected. The Device entered STOP Mode and Woke Up when it received data. But, My test project is not working. More Info: 1. The project was created for STM32L562 MCU. 2. Test board is L562-DK3. LED GREEN is not turn ON in my project if USART 1 configured. 4. Wake Up from STOP Mode is not working. 5. Receving bytes over UART is working when I disabled the code to enter STOP Mode ( SystemClock_Config_fromSTOP() ) and Configure the system clock after wake up from STOP Mode ( SystemClock_Config_fromSTOP() ). USART 1 is used. I have attached my project in zip file. Can you advise me, how to resolve it? Thanks

I'm working on a project that requires setup for various controls. I've built a main screen (MainMenu) which transitions into a sub screen (ZoneSetup) to move a few temp selection sliders, toggle some buttons, etc. for the setup. I need to pass that information back/retain that setup information so anytime the user returns the previously set information is present. I followed the pool example project to pass the information via the model (only focusing on the top slider right now), but when I update the slider (zone1) and try to return the program crashes.Also, another issue that I'm trying to solve is why one slide also affects/glitches the indicated text for a non-corresponding slider (ex: move zone2 resets/changes zone1). Any thoughts on these errors or how I should be doing this?See the attached .zip of the associated project.

Further investigating I see that the problem seems related to symbols exported for the se_interface, compiled into the 2_Images_SBSFU_CM0PLUS project and exported as .elf and .o file, thus included in the 2_Images_UserA__CM0PLUS project linking phase. Running STM32CubeIDE 1.6.0 on Windows 10 with WL firmware pack 1.0.0. I'm no more able to proceed... Is there something I'm missing?Thank you A quick update after further investigation:Looking for the 1st problem returned by the linker:c:\st\stm32cubeide_1.6.0\stm32cubeide\plugins\com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.9-2020-q2-update.win32_1.5.0.202011040924\tools\arm-none-eabi\bin\ld.exe: ../../../2_Images_SBSFU/STM32CubeIDE/CM0PLUS/Debug\se_interface_app.o: in function `SE_KMS_CloseSession':(.SE_IF_Code+0xbd8): multiple definition of `SE_KMS_CloseSession'; ../../../2_Images_SBSFU/STM32CubeIDE/CM0PLUS/Debug\se_interface_app.o:(.SE_IF_Code+0xbd8): first defined hereSeems that the linker is finding twice the symb
