STM32 MCUs

Hi, I've got a STM32U5G9ZJ-DK2 Discovery kit.I'm trying to setup the ADC to work with GPDMA doing a continuous acquistion of two channels into a large buffer of samples. I got it working perfectly fine with ADC4, but I just don't get it work with ADC1.From what I can tell it looks like the DMA Request from ADC1 is not forwarded to the GPDMA.ADC1 itself works, too. It works well in interrupt mode (triggering an IRQ after the sequence of two channels).Is the a special trick to enable the GPDMA request from ADC1, like is there a certain clock or power domain that must be enabled?  hdma_adcx.Instance = GPDMA1_Channel8; hdma_adcx.InitLinkedList.Priority = DMA_LOW_PRIORITY_LOW_WEIGHT; hdma_adcx.InitLinkedList.LinkStepMode = DMA_LSM_FULL_EXECUTION; hdma_adcx.InitLinkedList.LinkAllocatedPort = DMA_LINK_ALLOCATED_PORT0; hdma_adcx.InitLinkedList.TransferEventMode = DMA_TCEM_LAST_LL_ITEM_TRANSFER; hdma_adcx.InitLinkedList.LinkedListMode = DMA_LINKEDLI

Hello!I am trying to get an MQTT project to work, but having some issues. At some points randomly the program stops and does not respond to the remote server anymore. In hopes of figuring it out I tried to enable stack checking from ThreadX settings from CubeMX, and generated the code. BUT, whenever the stack checking was disabled, DNS was able to retrieve the IP address always. Now, it fails every time.The function "nx_dns_host_by_name_get" is called from the begging of SNTP thread. After calling the mentioned function, the return status is NX_DNS_QUERY_FAILED (0xA3). I have the DNS set up as to retry 3 times with a timeout of 10 seconds.Checking from WireShark I can see that the device did send out the query to get the IP address, and the router answered, but for some reason the packet was not received/saved on the device side. After that I get 3 different ARP packets from the router, which is trying to identify my device, but no responses. Finally, 2 more attempts are made by t

Hi,We're planning to integrate a file system with the VENC_SDCard example for the STM32N6x7:https://github.com/STMicroelectronics/STM32CubeN6/tree/main/Projects/STM32N6570-DK/Applications/VENC/VENC_SDCardWe found Revision 3 of UM1721 Developing applications on STM32Cube™ with FatFs dated February 2019 and were wondering if that's the most recent revision of the document?https://www.st.com/resource/en/user_manual/um1721-developing-applications-on-stm32cube-with-fatfs-stmicroelectronics.pdfWill

I am trying to start 6 virtual com ports over usb. I could start 4 using a USB composite pack made by a developer. From what I have read and tried, there are not enough endpoints for 6 com ports and only maximum for 4 (9 bidrectional EPs, 1 reserved for EP0; 2 IN EPs and 1 OUT EP per com port). Is it possible to start 6 com ports at all by reusing or bypassing an IN EP?

I am working with the Nucleo-STM32F753ZI board and using the internal OPAMP peripheral. The supply is 3.3 V, and according to the datasheet the OPAMP output should swing close to the rails, but in my case the maximum output I can get is only around 2.4 V.Has anyone faced this issue on STM32F7 series?Is there any configuration, calibration, or internal routing limitation that restricts the OPAMP output range on this board?Any guidance on how to achieve the full output swing (near 3.3 V) would be helpful.

Hy, I received the STM32N6 DK Kit, switched it on - and it crashes immediately. All demos run smoothly, but as soon as I start the AI demo, the display turns grey after approx 2 seconds. I power the device over USB port with my 65W Laptop Power supply, jumper JP2 set to 3-4 (5V_USB)When running the DCMIPP_ContinuousMode_FSBL example project, I see a stable, smooth camera image, so apparently no connection issues to the camera.Any hints?Best regardsHarald

Hi,I'm looking for some guidance on configuring the STM32N6570-DK so i can use the screen and onboard mic / headphone out jack.It looks like everything i need is in stm32n6570_discovery_audio.h and stm32n6570_discovery_lcd.h, and i did manage to get the screen going with some configuration from this repo: https://github.com/jpcano/STM32N6-digits When I then try and enable audio the following calls succeed:void Audio_Setup(void){ AudioInit.Device = AUDIO_IN_DEVICE_DIGITAL_MIC; AudioInit.SampleRate = AUDIO_FREQUENCY_16K; AudioInit.BitsPerSample = AUDIO_RESOLUTION_16B; AudioInit.ChannelsNbr = 1; AudioInit.Volume = 80; if (BSP_AUDIO_IN_Init(0, &AudioInit) != BSP_ERROR_NONE) { Error_Handler(); } if (BSP_AUDIO_IN_Record(0, AudioBuffer, AUDIO_BUFFER_SIZE) != BSP_ERROR_NONE) { Error_Handler(); }}after this the transfer callbacks never get hit and any calls to drawing the screen, HAL functions like UART sending or blinking a led also stop working.I did try the STM

I am looking for any example project that uses Azure RTOS FileX and LevelX using onchip flash.I understand the programming flash can be segmented and used for general purpose file storage but I cannot find any example across any series packages which uses the on chip flash. Is this even possible?I am mostly looking on how to set the levelx configuration parameters in STM32CubeMX. I know how to integerate the low level flash drivers from the HAL.

I've set up my STM32U5A9J-DK to use ThreadX and connect to my PC via USBX and Audio Class.I'm correctly see the Audio Device on my PC and I can easily stream audio to it.

  I'm using an ov2640 camera. When I use HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_CONTINUOUS, (uint32_t)camBuf0, (CAM_W * CAM_H) / 2);, HAL_DCMI_FrameEventCallback is called, but when I use HAL_DCMI_Start_DMA(&hdcmi, DCMI_MODE_SNAPSHOT, (uint32_t)camBuf0, (CAM_W * CAM_H) / 2);, HAL_DCMI_FrameEventCallback is never called. Why is this happening? Below are the relevant settings.

Hello all,I am working with the STM32WB series and using a 32 MHz crystal for the HSE (specifically the Murata XRCGB32M000F1SBBR0 on my custom board).To verify correct operation, I measured the analog waveform on OSC_IN and OSC_OUT using a low-capacitance active probe (Keysight N2796A). ObservationOn both my custom board and the official NUCLEO-WB55 evaluation board, I consistently measure the following:OSC_OUT ≈ 500 mVpp, ~400 mV DC biasOSC_IN ≈ slightly lower amplitude but similar bias (~400 mV)The two boards produce almost identical results, so this does not appear to be a layout or crystal-selection issue on my side. Documentation gapI cannot find any ST document (datasheet, reference manual, AN2867, or app notes specific to STM32WB) that specifies:Expected voltage swing amplitude on OSC_IN or OSC_OUTExpected bias pointTypical or minimum oscillator drive level in terms of Vpp for HSE on the STM32WB seriesThe datasheet provides the crystal requirements (ESR, CL, drive leve

I am working on a project using STM32N6570-DK. I now have a big problem with (1) how to run my code in a Flash and (2) how to connect the ST-LINK to stm32cube ide.I created a project “AYA” in cube IDE . Cube IDE asked if it is FSBL project or application project. I chose application, and all my work after are done within AYA_appliI finished the coding and testing from debug version to release version. Both with ST-LINK connected (with is integrated in the DK), and boot1/boot2 keys are set =00. My code runs correctly.TROUBLES came after the FLASH: I used STM32CubeProgrammer to write my .bin file to the -dk board. boot0/boot1=11,I chose this external bootloader  (MX66UW1G45G_STM32N6570-DK ) Erasing the full chipWrite my code (start address =0x07000000) to the flash and “verify successfully”Now, I switch boot0/boot1=00, and press the RESET button. However, NOTHING happens‼To make things WORSE: I switched back to the IDE environment, it says “Target unknown error 32 &nb

Hi, @krastThe readme for the VENC_SDCard_ThreadX examplehttps://github.com/STMicroelectronics/STM32CubeN6/blob/main/Projects/STM32N6570-DK/Applications/VENC/VENC_SDCard_ThreadX/README.mdstates:"The output is raw since no file system is used for now"but the first slide of the STM32N6 demo workshop - 11 Video encoder (VENC) in practice workshophttps://www.youtube.com/watch?v=25lEF4GgN8Msays that this example uses a FAT32 file system.I was wondering if there might be an error in the readme where it states "The output is raw since no file system is used for now"?Thank you very much for these examples - they're very valuable.Will

Hello,I'm trying to test FW update over I2C using RPI as host and STM32L432 nucleo board as slave on port I2C1 which according AN2606 (table 152) should be available. I've connected 4.7k pullups on PA6 + PA7 pins and perform NRST to 0 and BOOT0 to 1 and remove NRST pin. In this setup I perform i2cdetect on RPI and I'm getting i2c transfer timeouts for all addresses. When reset STM32 32 board i2cdetect command on RPI return empty table. Is that setup feasible or am I doing something wrong? Thanks. 

Hello,I am currently working on connecting an MT9M001 camera module to the STM32F429I-Discovery board and displaying the captured image on a PC.During this process, I am testing PWM output on the board, but I am experiencing an issue where the output voltage does not swing between 0 V and 3.3 V as expected.EnvironmentBoard: STM32F429I-DiscoveryIDE / Firmware: STM32CubeIDE + HAL (STM32CubeF4 package)Pin used: PB0 / TIM3_CH3 (Alternate Function, Push-Pull, no pull-up/down)PWM: Generated with TIM3 (frequency and duty cycle shown in attached code/images)Measurement: Oscilloscope (×10 probe, GND connected to board GND)IssueThe PWM waveform output from PB0 shows the following problems:The low level does not go down to 0 VThe high level does not reach 3.3 VBefore switching to PB0, I was using PA8 (TIM1_CH1), but I observed the same issue—the voltage could not drop to 0 V.I received advice that PA8 might be loaded by other on-board circuitry,so I moved the PWM output to PB0 (TIM3_CH3).However,

I have an application where I have enabled TX_ENABLE_STACK_CHECKING.  The application gets stuck in a do loop in the tx_thread_stack_analyze.c between lines 114 and 135.  (H7.3.1.0)  It is clear in the debugger that the loop will never complete.  The loop is checking for the stack fill pattern 0xefefefef using a binary search after checking the pointer are not NULL.     Here is the code:  /* We need to binary search the remaining stack for missing 0xEFEFEFEF 32-bit data pattern.

Hi,I am running the latest version of the VENC_SERVER application and am interested in the mode that uses no external memory. There is a define for 720p 30fps using internal memory only, but trying to compile it in debug mode results in a compile error with .bss data not fitting in memory.Could anyone advise on how to change the example or linker script to get the internal memory only version working?Thanks 

I have the need to access items of a scroll wheel that are not visible on the screen (but that are already initialized)For instance, I have a scroll wheel with each items a toggle button.With the ScrollUpdateItem I'm able to set the correct index to the item withScrollUpdateItem(alarmsItem& item, int16_t itemIndex) { item.setIndex(itemIndex)where setIndex is a function that set the index in the itemNow, this works but, I've got the issue when it comes to the callback of each toggle.For instance, once a callback is called, I need to process items different from the one selected so, I need to access the SelectorScrollListItemsFor some reason, despite setting SelectorScroll.setNumberOfItems(6); I'm seeing TouchGFX generating touchgfx::DrawableListItems<alarmsItem, 5> SelectorScrollListItems; so, when I try to access SelectorScrollListItems[5] I'm seeing the call to the assert  TYPE& operator[](int index) { assert(index >= 0 && index

I have been modifying the VENC_SDCard_ThreadX example to read in raw data through pipe0 with success. However, my bottleneck appears to be the SD card write speed; I understand that this example was designed to write compressed h.264 files - and it looks like it only writes at around 320 kB/s.Since I am capturing much more data, I would like to use exFAT instead of FAT32, and write to a UHS I card at max speed (SDR104). I defined FX_ENABLE_EXFAT within fx_user.h, but it I am still unable to write to an exFAT formatted card. fx_media_open() passes just fine, but upon inspection it appears that the available clusters always is 0. Am I missing any steps? Any insight would be appreciated.

Hi, I'm new to STM32 and FMC. I'm connecting STM32H755 to PCL6045, a motor controller which has data/address pins that can be access through FMC. This is what I've done so far:1) Configure the FMC inside CubeMX with clock set to 20MHz (max 20MHz reference clock according to PCL6045BL datasheet)I don't know why there's no unmuxed option in the CubeMX since I need to use the FMC_D instead of FMC_DA pins and the address pins start from FMC_A16 until FMC_A20. As for now I just connect FMC_DA to the data lines from PCL6045BL.2) Then, I try to write something to the selected register of axis XPclAxisWriteReg(ID_X, WRFL, 10);The base address that I use is 0x60000000. Every time I run the code related to PCL6045BL, it always gives a HardFault error.  I have also edited the main.c to use FMC_DATA_ADDRESS_MUX_DISABLE manually but it does not seem change anything. I don't know if I miss something important or my steps are wrong somewhere.

Hi there,I'm starting to use the NUCLEO-H533RE board to evaluate the H5 device family.RM0481 has some errors on the PLL configuration:Fig.55 on page 461 shows a VCO range 0 between 128 and 560 MHz, but the description of bit 5 of register PLL1CFGR (page 492) says 192 to 836 MHz, which is quite different. Which one is the correct one, please ?Section 11.8.12 name is incorrect page 497 (PLL1 written instead of PLL2).Regarding the best PLL setup:For the PLL1RGE possibilities, it select the input frequency range: between 1 and 2, between 2 and 4, between 4 and 8 and between 8 and 16 MHz. What would be the best choice for a input frequency of 8 MHz: between 4 and 8 or between 8 and 16 ? And if possible, explain why that is.Thank you,Kraal

Hi! I am having a lot of trouble configuring the ST-Link on my NucleoF466RE board to JLink with STLinkFlash.exe even after consulting different community posts and websites.I was able to connect to my board using STM32CubeProgrammer on my Ubuntu 24.04.2 LTS laptop and upgrade it with the STLinkUpgrade program below.Then I connected my nucleo board to my Windows VM from Virtual Box since STLinkFlash.exe can only be run in Windows. I have installed the right STLink and JLink drivers from SEGGER website and confirmed in my Device Manager that the STLink was detected.However, when I launched STLinkFlash.exe to upgrade my STLink to JLink, I got the error "ERROR: Timeout: ST-LINK/V2-1 did not enter DFU mode". I tried putting the nucleo board in DFU mode by shorting the BOOT0 pin to VDD or removing/connecting different jumpers available on the board, but none worked...Has anyone been able to configure their STLink on their nucleo board to JLink recently? Would really appreciate any point

HelloI was developing an application that uses BLE and low power mode. I was testing that on a custom board and when I measured the current consumption at STOP2_MODE, it was 1.7 mA.I expected that I had made a mistake. So I tried the low power examples found there STM32CubeWB/Projects/P-NUCLEO-WB55.Nucleo/Examples/PWR at master · STMicroelectronics/STM32CubeWB on my board and then using the P-Nucleo-WB55 and I found the current consumption is above 4 mA.Shouldn't be measured in micro-ampere? I am confused now, as I am using an ST example and a dev board, so it should work well.Thanks in advance. Best regards,Mahmoud A.

Hi, I am using STM32WBA55G-DK1, is it possible to use Audio In jack to send the input audio and at Out to receive the audio in a full duplex method. Thank you
