Hi community,I'm encountering a "network connection failed" error in my Cube IDE. Despite reinstalling the IDE multiple times, the issue persists. As a result, I'm unable to generate the code. Any suggestions on how to resolve this?

Hi there,There are a few projects where having a 16bit DAC instead of a 12bit DAC would be extremely useful.I am currently using the G4 series as analog synthesizer controllers and it would be fantastic to be able to use the 1MHz DAC as a 16bit audio output. I am using the 12bit DAC right now and it's actually surprisingly good when used carefully as an audio output, even when manually multiplexed externally. Having more precision here would be very useful.Are there any such plans?Thanks.

Can I use "STM32 ST-Link Utility" or "STM32CubeProgrammer" to program STM8MCU flash?If using "STVP", can it automatically detect the STM8MCU type? or require to configure "STVP" for the MCU type to be programmed.

Hello All, I am trying to use STM32H757I-Eval board for one of Development project and need to get one clarification regarding it.I am using Touch GFX Designer Version- 4.24.2, while creating a new project I can see STM32H747l Eval for Board Setup in Touch GFX, but not STM32H757I-Eval. Though I can run the sample code on STM32H757I-Eval  using STM32H747l Eval base setup, Will this cause any major problem in my future development, or I can use STM32H747l for any  STM32H7 Series Eval Board ? BR 

Hello Everybody, MCSDK:6.3.0 CubeMX: 6.3.0 Workbench : 6.3.0 Motor Pilot : 1.2.9 Power Board : IHM08M1(Rshunt=0.01Ω) Control Board : NUCLEO-G431RB Motor : BLDC 26w 24v/8 pole pairs / rpm=4k / rated current=1.8A/hall sensor   I would like to ask, in SPEED MODE under SMO + PLL, which API can be used to limit the Iq current? For example, if the rated motor current is 2A and the peak current is 6A,I want to limit the motor's current to not exceed 1.8A during normal operation. Which API or parameter should I use to enforce this current limit?Or is there no callable API, and I need to write my own condition checks?But since I am in SPEED MODE, is it still possible to impose a current limit? Thank you in advance to any expert who replies to my question  

Hi,  I followed the steps to install the Model Zoo, giving all attention to the Proxy settings. there is no chance i was able to install the requitements. issues with proxy.  Are the username and password in those settings should be my developer account? if yes what is the proxy address to continue? and the port?  if this is not the case, I am not behind a proxy and this should work. any idea could be wrong?  I tried the Miniconda, the anaconda shell, Windows power shell, Cmd, no luck.  Please advise!   Thank you.

Posted on October 17, 2017 at 12:08When using CubeMX, with STM32L476, for setting LSE drive capability other than 'Low Drive' the setting will not be implemented. This is due to the fact that the write access using bit DBP in PWR->CR1 is not set prior to setting RCC->BDCR value.The code generated in SystemClock_Config is:void SystemClock_Config(void){RCC_OscInitTypeDef RCC_OscInitStruct; RCC_ClkInitTypeDef RCC_ClkInitStruct; RCC_PeriphCLKInitTypeDef PeriphClkInit;/**Configure LSE Drive Capability */ __HAL_RCC_LSEDRIVE_CONFIG(RCC_LSEDRIVE_LOW);/**Initializes the CPU, AHB and APB busses clocks */ RCC_OscInitStruct.OscillatorType = RCC_OSCILLATORTYPE_LSE|RCC_OSCILLATORTYPE_MSI; RCC_OscInitStruct.LSEState = RCC_LSE_ON; RCC_OscInitStruct.MSIState = RCC_MSI_ON;....}where HAL_PWR_EnableBkUpAccess must be executed prior to __HAL_RCC_LSEDRIVE_CONFIG#cubemx #lse

Hello,I’m trying to create a simple program to test BLE functionality of my board. The board does not have HSE but it has LSE. I'm not sure if that is a problem. I'm using PlatformIO for the programming, configurations and building/flashing. When I upload the program to board it goes to infinite loop on if (!BLE.begin()) { while (1); } more specific on __WEAK void shci_cmd_resp_wait(uint32_t timeout) { for (unsigned long start = millis(); (millis() - start) < timeout;) { if (CmdRspStatusFlag == SHCI_TL_CMD_RESP_RELEASE) // <---- looping here { break; } } return; } This could be result of multiple reasons. Some things I have tested are:1. Use STM32CubeProgrammer to flash stm32wb5x_FUS_fw.bin to address 0x080EC000 stm32wb5x_BLE_HCILayer_fw.bin to address 0x080E0000and set application code target address to 0x08000000as per release notesCubeProgrammer is able to read FUS infos and also start wireless stack2.

I just read this document : https://www.st.com/content/dam/specialevents-assets/dc22/pdf/room-3-1-stdevcon22-session-nfc-for-wireless-charging.pdfIn page 13, there are two daughter boards, one based on ST25R3916 (NFC reader) and the other based on ST25DV-I2C (NFC dynamic tag). Both use STM32L476 as motherboard. In the following pages, they demonstrated an 286mw power transfer with the small antenna on boards. Which is a nice result.My question: does ST sell the two daughter boards and provide code and hardware design files as an official reference design? Or there are other kit for evaluating this solution? We are looking for a reference design based on STM32R3916/ST25DV-I2C. Also we are planning to use this solution in our medical device project.

i want to read every 10 seconds a few samples from a adc channel and let the dma bring the data to my variables.i have that working with 1 sample. the timer trigger the adc. adc trigger the dma channel and my HAL_ADC_ConvCpltCallback get called and the adc channel value is in the data variables. i can do this also with 2 channels. good.now i want read 2 or 4 samples from the adc channel. i can setup the timing there with the adc setup. thats ok.i want trigger the sampling every 10sek then read fast 2 or 4 samples. exact timing not relevant just fast.  but if i setup this  for 2 samples, the completion callback is now only called every 20 seks.  .. i think the adc does not trigger the dma 2x for the 2 samples , but only 1x and so the dma need 2 timer triggers until I have my 2 samples complete and so it takes 20secs instead of the 10sek.  please show a init of the adc so i can get 2 or 4 samples per timer trigger.i need help with setup combination: //hadc2.

Hi,first time using TouchGFX and I have been going through various tutorials but cannot find one that shows how to use TouchGFX Designer with a partial TouchGFX project set of files (first screenshot) generated by CubeMX (.touchgfx.part file extension and not a .touchgfx file). But instead of generating the 800 x 800 resolution, it generates a 32 x 32 pixel screen in the .touchgfx.part file (and opens a 32 x 32 pinxel canvas/screen also when that file is opened in TouchGFX Designer). I don't want to edit it manually just in case there are other settings in the files generated in the other folders that might be affected by this manual change. This is the CubeMX generated file:  { "Application": { "Name": "Display V1", "TouchGfxPath": "../Middlewares/ST/touchgfx", "AvailableColorDepths": [ 16 ], "AvailableLCDs": { "16": "LCD16bpp" }, "AvailableResolutions": [ { "Width": 32, "Height": 32 } ], "PostGenerateTargetCommand": "touchgfx update_project", "Fami

Hi,looking at the screenshot below of CubeMX in the LTDC, the total Width and total Height are non-editable (i.e. auto calculated) but they are one pixel less?For example, for the attached display datasheet:- Horizontal Sync Width (Editable) = 8 pixels- Horizontal Back Porch (Editable) = 7 pixels- Active width (Editable) = 800 pixels- Horizontal Front Porch (Editable) = 6 pixelsSo the total is 821 pixels instead of 820. But CubeMX displays 820 and it is not editable.Did I miss something? Do I need to change some other setting?Thank you :)  

Hello, I am unable to connect to STM32L562-DK via STM32CubeProgrammer , and when I do I get this error message13:12:59 : Error: ST-LINK error (DEV_TARGET_NOT_HALTED)Could someone please help me rectify this issue, Thanks  

Guys, I need help with ADC on STM32F407ZGTx. I have a project where I read 2 channels, ADC3_IN4 and ADC3_IN15. Since I need a function that has pin ADC3_IN15, I changed it to ADC3_IN8.The problem is that I don't know what it is about STM32F407ZGTx, at least mine, that makes a difference in the reading.On IN15, I had ranges from 54 to 920 in the final read value (this is the correct range).However, on IN8, reading the same voltage levels, it is reading from 64 to 706. In addition to giving me incorrect ranges (for example, in the middle of the reading, it should give me 313, but it is giving me 460, which is the value that I read with IN15 and which is correct).Are there any differences in the inputs? I've looked in several places, the STM32F407ZGTx manual, AN's, etc., and nothing, no one says anything. I tried DMA, nothing either. If I go back to IN15, the reading becomes constant and correct again.Attached is an image of the configuration on the STM32CUBEIDE.PS: I checked the val

Is it possible to write our own firmware for STA8135GA IC? I want to get the raw measurements from the baseband IC in STA8135GA and implement my own navigation algorithm and load the firmware to the IC. Is this possible?

Hi everyone, I'm currently working with the GNSS1A1 expansion-board based on Teseo-LIV3F module for a project. I have read that SBAS can be enabled on this module but I'm struggling to achieve it. I have tested to send some commands found in the doc, but first of all, I didn't get messages from the module like $PSTMSETPAROK, and secondly, the GPGGA message only shows the fix "1" (I think 2 is what I need).Maybe I didn't understand something about GPGGA messages or how to send the command, here's the line of code I used: if (GNSS1A1_GNSS_Init(GNSS1A1_TESEO_LIV3F) != BSP_ERROR_NONE) {Error_Handler();} if (GNSS_PARSER_Init(&parsed_GNSSData) != GNSS_PARSER_OK) {Error_Handler();} GNSS1A1_GNSS_Msg_t nmea_message;//char *cmmd = "$PSTMSBASONOFF*57\r\n";char *cmmd = "$PSTMSETPAR,1135,15*19\r\n";nmea_message.buf = cmmd;nmea_message.len = (uint16_t)(strlen(cmmd));if (GNSS1A1_GNSS_Send(GNSS1A1_TESEO_LIV3F, &nmea_message) != BSP_ERROR_NONE){Error_Hand

Hello,I am working with the STM32L432KCU6 microcontroller and noticed that it includes a 32.768 kHz crystal. I would like to confirm whether there is a separate crystal for high-speed operation or if an external high-speed crystal needs to be added. Could someone clarify this for me? Any insights would be greatly appreciated.Thank you!Nikunj

Hello,I am working on a project where a device is updated using dfu-util and utilizes the DFU driver from the STM32Cube(Programmer) drivers subdirectory. I would like to distribute these drivers to my customers and need to know, for the FOSS Software Bill of Materials (SBOM), what license is used for these files. I understand that stm32bootloader.inf and cat are licensed by STM under the SLA0048 license. Is that correct?However, what license is used for files such as WdfCoInstaller01009.dll and winusbcoinstaller2.dll? Where can I find the license information for these files? Are those property of Microsoft or STM?Is this the appropriate place to ask this question, or would there be a better forum for it?Thank you and regards,Ben 

I just bought this board and actually i have no idea what type it is. In the box there was product card for Nucleo-32 and that is definitely no Nucleo-32. Somebody know what exactly this is? Please Help!

Hello, everyone!I've been searching for an answer to this question for a long time, but so far without success.I have an STM32F410 and would like to use a timer to trigger ADC readings. However, TRGO does not appear as an option for the ADC trigger source.What am I missing? 

Hello, For some time the CubeIDE ioc editor looks like this: How can I fix it? BR, Roman!

Hi, I am setting up a p2p Client and p2p Server example using 2x B-WB1M-WPAN1 boards. There is no example I can find for the B-WB1M-WPAN1 so I have taken the Nucleo example and modified to suit the B-WB1M-WPAN1. I cannot connect the p2p Server to the p2p Client. Here is where I am at:- P2P Server is operational and available on the ST BLE Toolbox phone app. - P2P Server advertising settings as below- P2P Client is running and a button press will initiate a scan as below.  Questions:1. Does the p2p_Client application apply a device filter to the scan procedure, and if so what is being filtered and where can I modify this filter to find my device? Could this be my issue?2. In future I would like to only connect to devices with a specific ID, where could I set this ID and is there an automatic re-connect capability if the ID is fixed? Thank you for any help.
