I have created a project with a scroll wheel of 10 items, each item is displaying a single digit 0-9. Imagine an odometer for instance.  I am incrementing a variable(num) every second and usingscrollWheel.animateToItem(num, 20);to scroll through the list of items, it is working as expected until it gets to 9. Instead of it the scroll wheel continuing to rotate the same direction to 0 it reverses the direction of rotation and scroll past all other digits to get back to zero.  I have verified I have the scroll wheel set as "Circular" and it does indeed display the scroll wheel correctly as if it was circular.  Can I somehow change this behavior?

HelloI have my own board with STM32G071KBT6 microcontroller. I successfully comunicate with charger by PD protocol and I receive up to 21 V (PPS). But I need above 21V. I have power bank with AVS up to 28V and USB cable with e-marker (up to 240W). How to configure the stack to receive EPR parameters? I have no TCPP IC, but I use my own protection circuit. In the trace the EPR commands isn't present. I use STM32CubeIDE 2.1.1 and STM32CubeMX 6.17.0.Thanks a lot and best regards

Hello, we have a working design that is in production, but obviously cannot keep building because of the EOL variable capacitors. Our application is reader only, no card emulation. Since we don't need CE, do the variable capacitors need to be populated? Or can they be replaced with a fixed value capacitor? If the latter is correct, then what value capacitor to use? We want to minimize changes to the design since it is working well. In the future we will change to the ST25R300 bur right now we have to stick with the current design. Thanks,Derek

Hi, the extension version is 3.8.0, and it usually takes 5min to load, is that normal? Also, is there any CDN or dedicated server for Chinese users? cuz it's troublesome to download those bundles here. Thx

I got an error when downloading the .sfi file to STM32H753II using the STM32Programmer_CLI, my HSM version is V2AE.The error message is as follows: What its mean?V2AE cannot support STM32H753,and must use HSM_V1?or H753 cannot support SFI ?I’m a new use about SFI.Looking forward to your reply.

1. Where can I find pin function list for SPC582B60E1CD00X MCU. Package: eTQFP64  2. Suggestion on tool used to configure pins according to application and generate code.

  I am testing the board with a 14s Li-ion battery, but I am unable to read the cell voltages or configure any register through the GUI. I shorted the X1 and P2 power supply inputs and supplied 12 V to both. This was the only setup in which I could get a green ACK indicator. The results were: Only cell 1 showed a voltage, but it was incorrect (5.8 V). When I try to write or read any register, I receive an ACK, but the register value does not remain as written. I also tried to connect VBAT (P2-15) to C14 (by soldering R22) and GND (P2-9 or 23) to C0, but in this configuration the device does not start and the D13 LED does not blink. I tried several times, resetting all the power supplies in different sequences, but I still could not communicate with the device. After returning to the initial setup, powering the L9963 with 12 V, I was again unable to configure the ID or take any measurements.    

can someone help me with communication of l9961 chip to get voltages of 4s cells n current n charge accumulated by using esp32 or aurdino i dont have this chip n i am not a coder i tried my best but can get any data from the chip just i2c add 0x49 n this register 0x00 gives  0x41 n nothing please hep

Hello, we are in the process of developing a BMS using an STM32 and L9961. We were wondering if there was any source or example code of a full BMS we could have access to in order to speed up our development. I am aware of the example code on the product page but was hoping there would be something more fleshed out. In addition, I wanted to know if ST has a vault of cell models that we can use with the BMS for fuel gauging? We use Molicel P50B cells and plan to use Molicel P60B cells in the future. Thanks,Jon

Hi all.I'm new to STM, but have been designing and making embedded MCU products for over ten years.I was drawn to the STM32F105 series because of the USB DFU, to allow for field updates for prospective customers to update a product we're developing. Outside of USB DFU functionality, we just need 3x UART's, one GPI, one GPO. That's it. We steer clear of USART1 because of it's overlap with OTG_FS pins. We have got our product working using a ST-Link programmer, but not as yet using the USB DFU.Our USB connection just isn't enumerating. The wiring is correct when compared to off-the-shelf STM32 enabled boards with OTG USB interfaces.I am across the date code bootloader issue as described in AN2606, our chips definitely come with bootloader 2.2. I have VBUS from the USB-C tied to PA9 (OTG_FS_VBUS). Yes, USB-C but with the 5.1K resistors between CC1, CC2 and GND. NRST is pulled to 3V3 with a 10K pull-up. Boot0 and Boot1 is pulled to GND via a 10K pull-down, Boot0 also runs to a tactile NO p

Hi, I've just installed v2.14.0 for the first time, but it will not start up. All I get is the blue STM screen for a few second, then it disappears. I tried the command prompt start up detailed in This Post but I end up with an error message, shown below. I need help on how to proceed as I do not have JRE installed on my PC, but have had it in the past. I've tried re-installing STM32... but that didn't help Exception in Application start methodjava.lang.reflect.InvocationTargetExceptionat sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:62)at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43)at java.lang.reflect.Method.invoke(Method.java:498)at com.sun.javafx.application.LauncherImpl.launchApplicationWithArgs(LauncherImpl.java:382)at com.sun.javafx.application.LauncherImpl.launchApplication(LauncherImpl.java:321)at sun.reflect.NativeMethodAccessorImpl.invo

Is there anyway to increase the size of the icons in the top menu bar in the IDE?I am 70 now and my eyesight needs a wake-up here :)

Hi: My goal is to perform full-duplex I2S using the STM32F722RET6 part. To achieve this using the pins available on the package it looks like I need to use SAI2 (sub-block B) as the master/TX and SAI1 (sub-block A) as a slave/RX synchronized to SIA2.The configuration of SIA2 in CubeMX works fine.  However, when I attempt to configure the slave side (SAI1-A) the I2S option is greyed out (see below). Can anyone help me to debug this? Many thanks, Bruce.

Hi, I'm working on the STM32H7S7L86H with cube MX 6.17 and cube H7RS 1.3.0I need to use RNG in appli and boot context but it is grayed because it accept only one context. It also block the usage of the hash module.Any idea how to fix this ?Thanks 

Hi, I am trying to deploy a custom object detection model on the STM32N6-Nucleo board.I started with this:https://github.com/STMicroelectronics/stm32ai-modelzoo-services/tree/main/object_detectionThe training gets done, I get the performance metrics,python stm32ai_main.pyThe deployment code works fine, and I get the deployment complete message. But when I change from development mode to flash boot mode. It doesn't detect the camera.When I program the demo camera.hex filehttps://github.com/STMicroelectronics/x-cube-n6-camera-capture/tree/main/Binary/NUCLEO-N657X0-Qor object detection .hex file,https://github.com/STMicroelectronics/STM32N6-GettingStarted-ObjectDetection/tree/main/Binary/NUCLEO-N657X0-Q/USB-UVC-Displaythe camera works perfectly.Below are the training and deployment configuration files. These are the only files I changed. I would really appreciate any help in this regard. Thank you,# training configure.yaml file:general:project_name: custom_food_yoloxn_256logs_dir: logssav

Good day, ST community,I am writing to inquire about the possibility of updating the custom container used on each screen when a new change is made to the custom container template. Currently, I am required to delete the old custom container widget on all my screens and add the new updated container manually each time. Thank you in advance for your assistance.

Hi,I recently just finished the Yocto Bringup of a custom STM32MP15FAA1. Everything seems to be working in my application. I am now looking to begin development of the M4 in which I need access to either SWD or JTAG to do lower-level development. Unfortunately, I am having trouble connecting to either interfaces through both CubeIDE and also manually inputting OpenOCD in an IDF Powershell instance.I presume the easiest way to get to my goal is to setup SWD which on the MP15 maps to TMS (SWDIO) and TCLK (SWCLK) and I connected GND and VCC. My STLinkV3-MIME detects 3.3V on the reference line but can never connect to target. This is my first time working with a SOM as most of my development is on base Cortex M microcontrollers so I have a few questions.1. Is there anything in the M4 device tree that can be preventing JTAG from operating like the STPMIC? I do have M4 RPROC enabled in my device tree and the file descriptor is available for me to access.2. Does the boot mode matter? My end a

Hello,I am using STM32H750 and X-Cube-Crypto lib. I am working on a secure boot and want to calculate the app Hash value to check integrity. The library works fine for STM32L5 Mcu (Already tested) but not with STM32H750. I verified that I am using the correct lib libSTM32Cryptographic_CM7.a.The issue I get is a Hardfault triggered by a function in the lib. When I investigated more, I found that The Mcu tries to load data from a Peripheral Register not mapped for STM32H750 MCU.What do yo think could be the issue? Thanks,Ayoub

Hi,I am using the STM32CubeProgrammer API (v2.20.0) on Windows 11 using the Visual Studio UART example as a base. Everything works fine, however this issue is slowing down the programming workflow.After programming the MCU option bytes to RDP1 (or Closed state on some newer devices), there is a long delay (20 to 30 seconds) during the attempts to reconnect to the device. I already expect that the reconnection attempt will fail, so is there a way to reduce the time or number of reconnection attempts? Or a way to cancel the current operation? The time taken for failed reconnection attempts is 2x longer than the actual programming of the MCU.I noticed that there is a getCancelPointer() function in the API, but I have found no documentation or examples on how to use it. Is it possible to use this or is there some other way?Edit: Added info - using UART to program the device/** * \brief This routine allows to drop the current read/write operation. * \return 0 if there is no call for

Hi!I think a have found a bug in CubeMX for STM32MP257F processor.If you go to RIF - RISAB - VDERAM. You will find that the region size can only be 0x21000. That's more than 128 kB, according to the data sheet.SYSRAM1, SYSRAM2, SRAM1, SRAM2, RETRAM have 0x20000 as maximum region size.Question: If this is a bug, then I want to send a PR to the Github ST repository of the MP2 firmware. Can you guide me where the code is so I can make a PR?

Stm32l010r and s2lp using x cube sub ghz , for custom board just for coding only gpio button status, there are plenty of error, by solving all those 4-5 errors remain and their resolving method is to complete change of middleware files or some code left in file even check through free AI they finally there no such files in middleware add some, for adding it will not compatible with existing file. If tried in stm32wl33cc it also shows so many error but finally there something missing. There are some radio.spi.h and some similar files there in s2lp nucleo example in spirit 2 workshop project, but in s2lp middleware they are not available and look like board specific. If any available example and transmitting and receiving data for s2lp and stm32wl33cc.

Hello All,I have a certain STM32H7 that I can't erase sector 0 using STM32CubeProgrammer.I think it is because PROT_AREA_START1 and PROT_AREA_END1 are not correct. I am trying to get back to default values of PROT_AREA_START1 =0xFF (0x0800ff00)PROT_AREA_END1 = 0x00 (0x080000ff) to disable the protection.However I cant Actually change the option bytes through the programmer. I get:an error: "Expected Value for option byteP: "PROT_AREA_START!: 0xFF, fount 0x00"RDP is level 0 (AA)I am using ST-link. Thanks for any help,Trevor

How can I debug an STM32N6 project when using a load-and-run configuration? CubeMX generates two separate projects, and I’m able to debug each one individually when the BOOT1 pin is set high. However, it seems that if I only debug the application project, the FSBL never executes, so the system clocks aren’t initialized. What’s the correct approach to debugging both projects together?I came across a debugging guide, but it only applies to the XIP configuration.

Hello STM32 Community,I am facing a persistent "Target no device found" error when trying to program an STM32L073CZT3 custom board using a Nucleo-L073RZ as an external ST-LINK (CN2 jumpers removed).Hardware Setup:MCU: STM32L073CZT3 (custom PCB)Debugger: ST-LINK V2-1 (Nucleo-64)Connection: 5-wire SWD (SWDIO, SWCLK, GND, NRST, VDD_Sensing)Power: External SMPS providing 3.3V (Common Ground established between SMPS and ST-LINK).The Issue: While the ST-LINK pins show correct voltages when floating, the SWDIO (PA13) pin drops to 0V the moment it is connected to the target board.Pin 1 (VDD Sense): 3.3VPin 2 (SWCLK): 3.29VPin 4 (SWDIO):  (Measured 2.9V on ST-LINK side connection)Pin 5 (NRST): 3.3VTroubleshooting performed:Verified continuity; no physical shorts found between PA13 and GND.Attempted "Connect Under Reset" and "Hardware Reset" at 480 kHz.Schematic Check: I have a 10uF capacitor (C17) on the NRST line—could this be preventing the debugger from catching the reset state?Verified
