STM32CubeMonitor (MCUs)

For well-known reasons, I'm developing on STM32F4 using DAPLink, but encountered an issue when trying to track analog signal variations with STM32CubeMonitor. CubeMonitor seems unable to detect DAPLink. Is there any solution to resolve this problem?

Hi.Trying to connect a STM32G0 USB PD discovery kit using the linuxsoftware package. Device is detected find, just opening the serialport gives reasonable output (binary data which look like PDmessages). However the Java app doesn't work.On linux machine 1, it crashes with a segmentation fault in libX11# # A fatal error has been detected by the Java Runtime Environment: # # SIGSEGV (0xb) at pc=0x00007f3c022e0661, pid=2060337, tid=0x00007f3bbd1bb6c0 # # JRE version: OpenJDK Runtime Environment (8.0_412-b09) (build 1.8.0_412-b09) # Java VM: OpenJDK 64-Bit Server VM (25.412-b09 mixed mode linux-amd64 compressed oops) # Problematic frame: # C [libX11.so.6+0x18661] XInternAtom+0x41 # # Core dump written.

Dear all,haven´t yet found topic like this.I would like to...(need) make a windows executable file / application from a Cubemonitor flow.Any Idea if and how possible? Thanks and have a great day!

Hello. I can plot an array in STM32CubeIDE, STM32CubeMonitor and Keil uvision with the Time Graph or Logic analyzer in Keil using this function and viewing signal_sample: void plot_signal(uint32_t delay){ for(int i=0;i<_5HZ_SIGNAL_LEN;i++){ signal_sample=_5hz_signal[i]; for(int j=0;j<9000;j++){} // Delay } } The problem is that in all the software above, this gets plotted like a step plot, because the sample rate of the trace is so high it samples the constant value between the Writes to the signal_sample:  Example from keil. This is similar in other software mentioned   The only remedy i have found, is to printf the signal_sample to Matlab or Arduino Serial Plotter with UART. Because of printf, only the value of the actual array gets plotted smoothly, not the constant samples in between the writes. This would be good for me, the problem is i need multiple signal graphs at the same time, but UART can only send 1 signal array. I can't come up with

Hello, I want to use STM32CubeMonitor to debug the code. The .elf is imported into CubeMonitor, and the connection is built. However, clicking on "Deploy", the follow error message shows: "TypeError: Cannot read properties of null (reading 'variablelist')". I check the .elf file, it really contains "null".  The .elf is generated in STM32CubeIDE. The code can be excuted in both debug and normal run mode without problem. But the .elf contains "null". How to solve this problem? Thanks for support!STM32User

Dear Expert,I could view an array-buffer thanks to "https://community.st.com/t5/stm32cubemonitor-mcus/how-to-watch-an-array-using-stm32cubemonitor/td-p/225086/page/2"Following flow is my test-flow blocks. Cube-array block was referenced from above link.When I tried to draw double graphs, I can see only one graph is updated.(following is captured image, where upper graph is updated but bottom graph is not updated.)I attached exported json file of above flow-blocks. Is there any way to view multiple array graphs?Thanks in advance for your help.RegardsTiel 

We were following the ULPMark™-CoreMark User Guide for getting the ulp mark score but the STM X-NUCLEO-LPM01A is always throwing up some error and the LD2(ErrorLED) turns on causing issues. Also if in the case it runs its always telling    “>! Validation failed, too little runtime: 0.014000000000000234” “>! Set iterations above 749999 for Energy run”. Even after using the same parameters its throwing the same error. Also at 1ms the connection is never achieved and fails.It would be great if you can guide us on this.

Hello ST Community,I'm using STM32CubeMonitor-Power (latest version) with an X-NUCLEO-LPM01A board (firmware v1.0.8), and I'm facing an issue in static current measurement mode.Problem Description:In standalone mode, the static current displays some current2, which is expected.However, when I take control via software and press “Start Acquisition”, the session runs for only ~0.1 seconds and then stops automatically, without any error message.Additional Observation:In dynamic measurement mode, the current acquisition works as expected.This suggests that the board and measurement path are functioning correctly, and the issue is specific to static mode under software control.Is there any recommendation to fix this issue?Thank you for your support.

Hi Is there a way to communicate with the STLNK-V3PWR to extract current consumption?  (the Acquisition & Replay output).  I would like to communicate with it via Python (or other language) to automate current consumption measurements? Thank you.Pete.

I want to store the stm32 cube monitor graph data or store the corresponding variable data in to xml sheet. How can I do that.

Hi, I'm using a fresh debian testing (12) and when i try to launch "SetupSTM32CubeMonitor-Power.jar", i get the error :Command line arguments: SEVERE: java.lang.ArrayIndexOutOfBoundsException: Index 70131 out of bounds for length 22674Debian is not in the supported operating system, but ubuntu should not be so far. I found on the forum, that the error occured on stm32cubemonitor on ubuntu recent version.Is there a patch/upgraded planned or anyway to make it run ?Could someone on ubuntu tell me if it work on it ? Thanks in advance,

Dear staffs,I'm going to use "STM32CubeMonitor" for several Nucleo boards, such as Nucleo144 of STM32H563.But, when I try to invoke, following dialog appears and does not proceed.Why ?Thank you 

I'm currently facing a frustrating problem with STM32Monitor. When I'm trying to parse data, the progress bar gets stuck at 10%. As a result, I'm unable to pull the project data list.Hardware environment: Windows 11

Hello,i use STM32WB05KZ for the bluetooth.With software can use to programme or to do some BLE test ?thanks

I downloaded Cube Power Monitor and am trying to use it to connect to the LPM01A. I have downloaded and installed the W8 version of the virtual com port driver. I can select the board in the drop down menu, but when I hit "Take Control", a dialog box pops up with the message `error pwr get`. When I hit okay, another pops up with the message `Get current range command failed` with another message below it `ERROR TIMEOUT`. Hitting ok again gives yet another dialog box with the message `Board has been released due to connection issue. Please unplug and plug the board`. I've tried unplugging and plugging it back in and the same thing happens. I am currently on Windows 11, but I've tried on a different windows 10 machine and the result was exactly the same. Any help would be appreciated. Please also take a look at my other question for something that might be related... having lots of issues with this board so far...

Mac refuses to start STM32CubeMonitor, it seems the app is neither code signed nor notarized.Happens with latest release 1.10.0

Hi  I have the cube monitor plugged in , and running the cube monitor power application. I had it working on my old computer (Windows 10) , but had to install the USB driver of ST web site. Since moving to my new computer, I cant find the driver again. Anyone point me to where it will be? My new computer is WIndows 10 too, and installing the cube monitor power application doesnt install the driver Many thanksScott

Hello,I would like to ask a question, if it is possible to access UCPD monitor via USB-UART bridge? I am following tutorial AN5418, with nucleo G0B1RE and SNK1M1 shield. Everything works fine when I use st-link, but when using uart bridge I dont see the board in board selection of UCPD and can log data only to UCPD trace...I have found out, that one can make it to work when one desolderes SB16 and SB15 from st-link on nucleo and connects LPUART to TX and RX of JP6. But is it also possible to make it work with USB-UART bridge from another vendor?Thanks,Marosh @Nicolas P.
