STM32CubeIDE (MCUs)

I recently changed the configuration of working product from HAL API to LL API to improve performances.Unfortunately, the LL initialisation code generated by the STM32CubeIDE for the ADC was incomplete, and forgets to set the PCSEL register when needed, resulting in the ADC converter just generating random numbers.By comparing the registers with the 2 initialisation methods, I found the solution by adding LL_ADC_SetChannelPreselection() when needed.Below is the code generated by the IDE, and with the 2 missing calls added (after the BUG:  comment)Note: the LL_ADC_SetChannelPreselection() calls should NOT be added when using analog only pads, like PA0_C, PA1_C, PC2_C, PC3_C. However, for general I/O pads, if LL_ADC_SetChannelPreselection() is missing, then the ADC just convert noise. /** Configure Regular Channel */ LL_ADC_REG_SetSequencerRanks(ADC2, LL_ADC_REG_RANK_1, LL_ADC_CHANNEL_12); LL_ADC_SetChannelSamplingTime(ADC2, LL_ADC_CHANNEL_

Hi, I pull out the official example from IDE, and do a debug run. I found out that the initialization always return FR_NOT_READY , after running to this lineres = f_mkfs((TCHAR const*)SDPath, FM_ANY, 0, workBuffer, sizeof(workBuffer));- inside this line, it goes to ff.c and reaches the following lines:/* Check physical drive status */stat = disk_initialize(pdrv);if (stat & STA_NOINIT) return FR_NOT_READY;and STAT is always = 1 (failed)This example was taken from IDE's EXAMPLE SELECTOR, should be official, and bug-free.Anyone has any clue what to do when  FR_NOT_READY is faced?It is not cards problem, my 2 cards works normal on PC, and formatted with 4096 size, the max of STM's FATFS can handle.  

If you have imported an project/example to your workspace and you delete it - ticking the box to delete the contents - it does not actually delete the folder.  Say you imported the Nx_Network_Basics example~/STM32CubeIDE$ ll workspace_1.16.0/total 16drwxrwxr-x 4 jannek jannek 4096 Aug 19 23:21 ./drwxrwxr-x 3 jannek jannek 4096 Aug 19 19:20 ../drwxrwxr-x 3 jannek jannek 4096 Aug 19 19:19 .metadata/drwxrwxr-x 8 jannek jannek 4096 Aug 19 23:21 Nx_Network_Basics/You then choose to delete it.You chose to delete the resources and also projects contents on disk.and press OK, you would assume it's all gone - right?Nope, the folder remains.This will then prevent successful import of the same project again, as the folder already exists (which is annoying).You must delete the folder yourself manually.This is a bug.- Might be in Eclipse itself.- Easy fix: link the known issues of STM32Cube IDE with the known issues of Eclipse itself, too?- Proper fix: delete also the folder.   

Hello~I am testing my stm32f103rb board with ethercat board(as shown). The trouble i am having is that there is no easycat library to use. I did some research and only found the .cpp easycat library. I'm using stm32ide and written in C language. This is causing me problems. Is there a header .h and source .c library file for easycat? Please help me.Thank you so much!

Hello,when creating a new project, and I start typing in the "Commercial Part Number" field, the cursors moves to another field after the first character.Here I was trying to type "Nucleo" and the cursor moved to the other filed after the first keypress.  

HiI have STM32CubeIDE 1.16.0 installed on Ubuntu 22.04.4 on a DELL with Intel i7. Whenever I close the IDE with the MX interface open, it cannot start again, and it complains about Java. It is probably an Eclipse error, but it is a bit of a pain. I know I just have to close the ioc file before closing the IDE, but I forget. It would be nice if someone had a look at it.Have a nice day.Erik

Hello ST team,It seems there is a bug on the latest revision CubeIDE (1.15.1) to use the DCMI function. The DCMI is able to active on the board Nucleo-H743ZI2 or Nucleo-H753ZI with STM32CubeIDE (1.14.1). But today, when I installed the latest revision (1.15.1), the it shows DCMI is an exclusive choice. As shown below, there is no pin conflict as all the pins have not been set up. Thx.  p.s. No issue on STM32CubeIDE 1.14.1. See below.

I update to V1.16 and found, that my project cannot compile anymore.Problem are compile errors, double definitions and so on. I did not change the code, just updated and regenerated everything include the code generation of CubeMX ( from within the ide ).So it turned out, that now the generated code is generated to an folder called Application beside the Core folder. And there are lots of files as linked resources within the project settings.These linked resources are causing the problem, as the compiler tries to complie the same file double. once the real file and then again the linked file ( which of course is the same ).Is that intended?Can I adjust the cubemx to not create linked files and can I adjust whether to use "application"/"core" or not or whatsoever?best regards,Stefan

When installing for example the Nx_MQTT example for B-U585IOT02A you need accept a license for CubeFW U5 1.6.0. You are supposed to view it 1st. However, at least with Ubuntu 22.04 and FireFox as default browser (default for Ubuntu 22.04) you can't view the file.  

Anyone any idea what is going on here please? GPIOA, B and C show up correctly, but D onwards is showing GPIOC registers! Proceossor is H563 and I'm running Cube 1.16.0 Build: 21983_20240628_1741 on Linux.

Does STM32F423ZHT6 support X-CUBE-DISPLAY? If yes means give an example.

I have been asked to remove (uninstall) the STM32Cube IDE and replace it with another version. However, the instructions found how to uinstall STM32Cube IDE suggest there should be an uninstall.sh script in the /opt/st/STM32CubeIDE_<version> -folder.

Hi,For my project, I am using an M24M01E-F I2C EEPROM. In this application need to store sensors offset values (float data type) in EEPROM. whether it can be able to write/ read float value. Regards,Rishvana M

Hi,Recently, when I tried to install the Debian Linux version of STM32CubeF4 on my Debian Linux (v12.5) Bookworm system, I began by trying to install a package that included Server 2 in its name. The server install hung at 50% installed. Each time I subsequently opened/closed the Debian Discover file manager, a new instance of the server install was initiated culminating in 6(!) instances of the server install all hanging at 50% installed. Now, Discover is displaying the following message:E: The package st-stlink-server needs to be reinstalled, but I can't find an archive for it.E: Unable to apply corrections for half-installed packagesAlso, while this situation persists, I am thereby blocked from installing other software on my system using the "sudo apt install package-name" or "sudo apt-get install package-name" processes.Since switching off the system last night and rebooting the system this morning, this server zip package has disappeared from my Downloads folder. ???What must I d

I use the dark theme of the IDE and can find no preference settings to change the colors for the build analyzer output. The IDE shows the usage info with light gray text on a bright green background which (to my eyes) is almost unreadable. I say almost because if I really strain I can make out the info. I need more contrast to make this info easily readable.I've tried searching a variety of terms in the preferences search bar, as well as scrolling through every color/font setting I can find, but to no avail.Can anyone point me to where the settings for these UI elements are so that I can change them?Thanks!

It is done incorrectly that after pressing the "Debug" button while the project is being compiled and loaded into the MCU - it remains possible to press the "Debug" button again, which is incorrect (this will corrupt the normal course of the process), until the project is completely compiled and loaded into the MCU, the button should be inactive. Debug button and Run button should remains inactive until Debug or Run process will ready

When starts debug my project in CubeIDE Version: 1.16.0 Build: 21983_20240628_1741 (UTC) there is always connect from third attempt. Because why and how can I fix it to connect from first attempt? Thank you

When I start debugging - there is unnecessary focus switching between the startup_stm32f* editor, the focus is constantly broken from the current window and CubeIDE switches the focus to itself - this is strange behavior. Is it possible to remove the focus switching at the end of the build and the chaotic opening of windows during the build and firmware process? I have debugging setting to start from main()I would like debugging to start quietly in the background - the progress bar at the bottom right shows the process and the status "Linking/Connecting/Dowloading/Ready/Paused" and that's it   

Hi, I'm a newbie in this embedded board and I'm having a hard time setting up the PWM pins. I'm currently using an STM32F103RB with a bldc motor driver shield that has pin 5, 6, 9 for PWM input.The corresponding pins for them are PB4, PB10, PC7 so I tried to activate pwm for those.However, PB4(TIM3_CH1) and PC7(TIM3_CH2) couldn't be configured at the same time and when I tried to set PC7 after setting PB4 to TIM3_CH1, PB4 automatically switches to some other pin that can be compatible with PC7.Why does this happen even if they use the same timer but have different channels?

Hello,My project was working fine, but suddenly I cannot debug or run it with the original bootloader anymore. The project is created and generated by TouchGFX Designer.This is the error message I get when I try to debug/run the project.I am sure that the bootloader bin file is already there in the correct path and the corresponding path is also already correct in the linker script.If I remove the bootloader part from the linker script and flash my customized bootloader from CubeProgrammer then I could run the application but as I said I need to debug the project.Anyone have such problem before or know how to solve it? BR,

I am trying to use the DS18B20 temp sensor on a stm32h7 board to display the current temperature using putty, and if the temp is higher than 45 degrees celsius to display a heat warning, but for whatever reason the sensor is not beign registered. I have connected the vdd cable to the 5v pin and the data cable to the A2 pin, I have configured the A2 pin as Output Open Drain with pull-up and I think that the sensor is not being registered.I have attached my code so farI also get abnormal readings like these, no matter if the sensor is plugged in or not:"""Heat Warning! Current Temperature: 2693.75°CHeat Warning! Current Temperature: 1515.38°CHeat Warning! Current Temperature: 821.12°CHeat Warning! Current Temperature: 3424.06°CHeat Warning!

Hello,I am a Lab Instructor at the University of Waterloo, Ontario Canada.I am using the STM32CubeIDE tools in my lab. There are about 200 students using my lab every term. I have the STM32CubeIDE tools running on 24 workstations in the lab and I have the whole class running these tools for an assigned embedded project. Each student has his/her own  NucleoThe situation for which I am trying to gain some kind of supervisory control, is with the software updates for the tools. I want to use a consistent software version for the whole of each term. But my students keep getting these update notices from the web and too many times, things get mixed up with different versions of software components running at different workstations.Question: Is there some kind of option for not allowing software updates to happen? If so, I would like to enable that option whenever the STM32CubeIDE tools are invoked. Then, after the term is over, I can do a common update on all workstations.Thank you for
