Solved

hi all,  i am using STM32U585 controller which is having a internal UCPD controller.my requirement is to create a module which can act as host and device using USB type C. i am taking the hardware connection as same as stm32U585 eval board(and adding a external crystal for the host part) since it is supporting both host as well as peripheral role. is there any specific code or documents available for the USB DRD/OTG implementation using TYPE C. all i can find the independent host and peripheral examples from ST. my actual requirement is : host: USB MSC when the module connected with flash drive it will work as mass storage (source the power) device: USB CDC ACM when module connected with the PC it is work as VCP terminal and (sink the power)   I implemented the code for host and device code independently , the problem is where we changing the roles and power delivery.  I am planning to implement the same schematic as in B-U585I-IOT02A which is using a exter

Affected driver library: STM32Cube_FW_U5_V1.2.0File: stm32u585xx.hThe definition of CRS_CR_TRIM_Msk is wrong.Currently it is:#define CRS_CR_TRIM_Msk (0x3FUL << CRS_CR_TRIM_Pos) /*!< 0x00003F00 */But instead it should be:#define CRS_CR_TRIM_Msk (0x7FUL << CRS_CR_TRIM_Pos) /*!< 0x00007F00 */(The TRIM field has seven bits, not six)

I've noticed that the frequencies written in the reference manual are different from the ones used in the HAL.Is there a good reason they are different? Which ones are correct?I attached a screenshot from page 407 of the reference manual.https://www.st.com/resource/en/reference_manual/rm0456-stm32u5-series-armbased-32bit-mcus-stmicroelectronics.pdfAnd a screenshot from github stm32u5 HAL stm32u5xx_ll_utils.cThank you

Hi, Is it possible to run on the M7 core a piece of program (subroutine call - no input, no output parameters) written, compiled and loaded for the M4 core (i.e. to have global access to program code)? Best  

Hi,please anyone could help me out how to resolve the issue regarding the ST-link upgrade. when i am trying to upgrade it is throwing an error "ST-link not in DFU mode. please restart it".I am facing this issue after updating both STM32cube IDE and STM32CubeMX to the latest versions.   Thank you,Deekshitha

What is the camera protocol used by STM32F7508-DK?MIPI or DVPWhich cameras does STM32F7508-DK module support?

Hi, everyone.I recently bought a STM32H750B-DK devboard to try and learn to program microcontrollers. I'm beginning to think I should have started with something simpler...I tried following the "getting started with STM32" tutorial from the wiki. SO, I installed the STMCubeMX, STMCUBEIDE and STMCubeProgrammer as instructed. It seemed to be aimed at the L4 series, so of course I swapped out that for the H7 embedded software packages.This let me load up some demo software packages. I started with LTDC_Paint. Loaded, Built, and tried to write to the board.The first attempt failed, but I discovered I needed to get an external loader to put the code onto the external memory. I selected the MT25TL01G_STM32H750B-DISCO since that was the closest match to my board. This allowed the debugger to apparently write the code to my board. The result: a blank white screen. I tried building and rewriting the TouchGFX example program (I have a feeling this is what came pre-installed on the board given th

There are a couple of minor issues running Cube IDE 1.13.2 on the latest macOSFirst the "splash" screen during startup gets displayed upside down.Secondly the app appears as "NewApplication" in the menu bar.See this video. 

Currently, I'm using CR95HF on our product which went into mass production already.  The tag is small with diameter only 9mm.  In the field, we are seeing a few percentage of unsuccessful read from the first read and need to retry several times.  How can we increase reading distance?  Is it possible to boost the transmit power from the reader chip? The tag has NTAG213 on it.  Our reader antenna is in octagon shape.    

Hi STI am using STM32CubeMX v6.10.0 with selected MCU STM32H563ZITx.When configuring FDCAN1 I may have found a bug in the tool. The below two Nominal Time Seg1 and Seg2 say that the lowest value is "2" and the tool is limiting setting it to "1" which I think is a valid setting.The RM0481 Rev 1 says that the minimum value that is interpreted by the hardware of that value is "1" (when register segment is set to "0")Can someone please verify my findings?BrImre

I want the user to hold a button for at least 3 seconds before it triggers its interaction. So I created a Repeat Button, because the documentation says on delay: "Delay specifies the time (ms) to wait when the button is pressed before starting the loop of triggers."But when I configure a delay of e.g. 2000 ms and an interval time of 8000 ms, it triggers immediately and then after 2 seconds (and then every 8 seconds). Is this misleading in the documentation or a wrong behavior of the button?

I am using STM32L4R, the VBAT pin is powered by 3.6V +/- 2% & VDD is powered by 3.3V +/- 2%.I think it is okay to have VBATT as 3.67V_max since it is still less than Absolute Max limit of 4V.I think it is okay to have VBAT pin & VDD pin at different voltage level since at a time either one of these is selected to power RTC. Also, the voltage rating mentioned in electrical specification is in absolute terms (not relative to VDD).Please confirm if my understanding is correct. 

We are an industrial automation company from Suzhou, China, and we want to develop an IO-Link device product recently.We want to adopt the STEVAL-IDP003V1 + TeConcept solution.But I don't know how to get this support, such as how to buy the STEVAL-IDP003V1 kit? How to buy TeConcept device stack and debugging tools?

Hi,    Good morning, everyone. I'm new to IOT. So, I need your help for how to connect and use STM32L4S5VIT6 and AWS from the scratch. Could you please help me. Demo video or any sample code and share any related document for understanding purpose it is very helpful for us.

I am using STM32CubeIDE v1.13.2. When setting oversampling for ADC3 on STM32H723, the ratio value is incorrectly generated to exactly the number that is typed in the GUI:  hadc3.Init.Oversampling.Ratio = 32; which is then on lines 725-735 in stm32h7xx_hal_adc.c written directly to the CFGR2 register: MODIFY_REG(hadc->Instance->CFGR2, ADC_CFGR2_OVSR | ADC_CFGR2_OVSS | ADC_CFGR2_TROVS | ADC_CFGR2_ROVSM, ADC_CFGR2_ROVSE | hadc->Init.Oversampling.Ratio | hadc->Init.Oversampling.RightBitShift | hadc->Init.Oversampling.TriggeredMode | hadc->Init.Oversampling.OversamplingStopReset ); however, for oversampling on ADC3, there is this mapping for the values:000: 2x001: 4x010: 8x011: 16x100: 32x101: 64x110: 128x111: 256xBy pure chance, this works correctly for values 2, 4 and 8 (as OVSR is offset by 2 in CFGR2). Higher values are of course broken.The generated value should probably be from the ADC_HAL_EC_OVS_RATIO. As this is different from ADC1 and ADC2

Hi, as advertisedof course , but no : - no UART4 as the datasheet , page 14/200 (false because UFQFPN48 has 4 more pins than LQFP48 ?)- no UART4 as CubeMx : PC10 and PC11 are present , but no UART4I have got a STM32G431CBU6 from an chinese board maker , nice board with amazing MCU tried UART4 as STM32duino's Serial4 : it works , so USART4 is present , officially or not ...(didn't try the handshaking lines)

I'm trying to get a L452 to bring up a VCP under ThreadX/USBx, so I followed the instructions in:https://community.st.com/t5/stm32-mcus/how-to-implement-the-usb-device-cdc-vcom-in-stm32-using-the/tac-p/629402#M738It seemed pretty straight forward, it compiles, runs, creates the read and write threads, the main thread exits appropriately, but the USB device never enumerates on the bus.Just to make sure that my board works (Nucleo with a USB-B connector wired into PA11/12, ground, and +5), I can put the processor into bootload, it comes up as a USB BOOTLOADER, and I can use CubeProg to push code. So the physical connection is okay.I must be missing something. Is there something weird with the L4 that needs code tweaking? Can you please take a look?I've attached the project below.

hello.As I said in the title, I would like to know the exact Bluetooth version information for both MCUs.I recognize the Bluetooth version of stm32wb5mmg as '5.0'. However, the datasheet and MCU website say that the Bluetooth version is '5.4'. Which version is correct?I would also like to know the Bluetooth version information of stm32wb1mmc.Is there a way to find out the exact Bluetooth version information? The datasheet is attached, and below is the MCU website I checked.stm32wb5mmg website:https://www.st.com/en/microcontrollers-microprocessors/stm32wb5mmg.htmlstm32wb1mmc website:https://www.st.com/en/microcontrollers-microprocessors/stm32wb1mmc.html

The last update of CubeIDE is like below:I have this warning and I don't understand what it is:"C:/ST/STM32CubeIDE_1.3.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.externaltools.gnu-tools-for-stm32.12.3.rel1.win32_1.0.100.202403111256/tools/bin/../lib/gcc/arm-none-eabi/12.3.1/../../../../arm-none-eabi/bin/ld.exe: warning: FW_code123_R1-0.elf has a LOAD segment with RWX permissions" After this CubeIDE update, the FW update is required for ST_Link/V2 ProgrammerI pressed the "Open in update mode" button.The error bellow is present now, like bellow:What can I do to solve this aspect?I can't use the programmer to program the micro controller or to make a FW debug.Thanks in advancedConstantinP.S.before of this last update, the mentioned warning was not present. I used the same FW code. And the ST_Link/V2 FW update was working every time when the CubeIDE requested for itThe ST_Link/V2 programmer is OK. I use it on the other PC and I test it also using ST_Link Utility and on this tool

Hi everybody,I am trying to use the audio on stm32f746g-disco.I can hardly find a tutorial for this.Many solutions got their way to solve it and left not much details.lots of the solutions guide to the examples in CubeMX , but they seems a little bit old and I can't figure out what is the examples are doing For now I tried to init SAI2B to receive data but it not like getting any valid data or triggering half and complete callbacki've attached my main.c ,and the setting of SAI B and its dmatake a look if you have timethank you

Microcontroller: STM32L051R8Tx (MSI used as system clock, set to 4.194 MHz) Board: custom design (no Nucleo etc.)The LPTIM1 is clocked by an external LSE (32,768 kHz, +- 10ppm).IDE: Keil uVision V5.36.0.0Compiler: ARM Compiler “Use default compiler Version 5”I scheduled a recurring task with help of LPTIM1 and it’s IRQ. The timer is set to 500ms. The task processing time is around 130ms (measured with help of TIMER21). I observed a latency which is becoming visible over time. After 4080 interrupts (after 34:00 minutes, 4080/2/60) the timer is lagging ~9 seconds (in my application, a few hundred milliseconds wouldn’t be a problem at all). In case this time is getting “lost” evenly per interrupt it would mean >2ms per interrupt. It seems to be unrealistic latency, isn’t it?Secondly, if I replace the task by a delay function of the same time duration (or simple comment the task out), there is no considerable latency at all. 34:00 minutes on the microcontroller equal to 34:00 minutes on
