I am working on a project using the STM32WB55xx series. I'm trying to read the Device Information Table (AN5185 Section 6.6.1, pg 17) using a bash script and the STM32 Programmer CLI.According to the documentation (AN5185 Section 1.2 page 3) I should be reading the IPCCDBA option byte to get the device info table address at the start of SRAM2a. The IPCCDBA value is 0x0, so the device info table address should be located at address 0x20030000. If I try to use the CLI to read at address 0x20030000, I get all zeroes in response.If I read the same address using the STM32 Programmer GUI, at first I get the same thing:However, if I switch to the CPU tab in the GUI and hit 'Run' first, I can check address 0x20030000 and I find a value of 20030890: Then, I can read address 0x20030890, and I find the device info table, including the 'table valid' bytes 0xA94656B9: Success! It seems that hitting the Run button makes all the difference for the GUI.So now going back to the CLI, it appear

I am using STM32L073.When using this ADC, the EOC of the flag ADC_ISR for which AD conversion has been completed does not change unless the EOCIE of ADC_IER is set.is it right.

I have the STM32L475 working in STOP2 wake up as WFE based on the RTC. I would now like to add in an external interrupt source (WFI). There doesn't appear to be a way to use both a WFI and a WFE as wake up. The only way I could see would be to have an external clock provide similar timing as the RTC, but that would defeat a lot of the low power benefits. Is there anyway the RTC wake up can be gated with an external signal?

I have migrated code working fine on STM32F767 to STM32H7A3.The strange thing is DMA2D_IRQHandler does not get called upon memory-to-memory transfer complete. I call HAL_DMA2D_Start_IT() function, it returns no error, it does what it should, I can even call it subsequently but DMA2D_IRQHandler is not fired.What could be the reason? Below is what I have checked, all settings seem to be OK.I am puzzled.uint32_t isr = hdma2d.Instance->ISR;           //  interrupt status register [0]uint32_t ifcr = hdma2d.Instance->IFCR;         //  interrupt flag clear register [0]uint32_t cr = hdma2d.Instance->CR;             // control register [8961]uint32_t v1 = __NVIC_GetVector(DMA2D_IRQn);&n

We have in production a display product using STM32F496. Currently we offer this with our own software only, but are considering opening up software development to 3rd parties. We would love to be able to integrate this with STM32CubeIDE and TouchGFX in the same way as ST's own discovery and eval boards.I've found this information on how to develop an expansion package, is there a similar mechanism to integrate a new development board into the environment?

The ST data sheet says: “…uses a default device address of 0x52.But is that the 7-bit base address, or the Write address?

HiI'm using the dual image function on a 512kB STM32G474. I like to adjust the bootloader size to 32kb because my user App is too big.In the AN5056 there is a note how to adjust it, but I'm not sure if this lines in the file low_level_security.h are correct? Can anybody help me please?#define SFU_PROTECT_MPU_EXEC_SE_RGNV MPU_REGION_NUMBER7 #define SFU_PROTECT_MPU_EXEC_SE_START FLASH_BASE /*!< Flash memory area */ #define SFU_PROTECT_MPU_EXEC_SE_SIZE MPU_REGION_SIZE_16KB //eud MPU_REGION_SIZE_32KB #if defined (__GNUC__) #define SFU_PROTECT_MPU_EXEC_SE_SREG 0xE0U /*!< 32 Kbytes / 8 * 5 ==> 20 Kbytes */ #elif defined(__CC_ARM) #define SFU_PROTECT_MPU_EXEC_SE_SREG 0x80U /*!< 32 Kbytes / 8 * 7 ==> 28 Kbytes */ #else #define SFU_PROTECT_MPU_EXEC_SE_SREG 0xC0U /*!< 32 Kbytes / 8 * 6 ==> 24 Kbytes */ #endif /* (__GNUC__) */ #define SFU_PROTECT_MPU_EXEC_SE_PERM MPU_REGION_PRIV_RO #define SFU_PROTECT_MPU_EXEC_SE_EXECV MPU_INSTRUCTION_ACCESS_ENABLE #define SFU_PROTECT_MPU_EXE

We have a project that contains too many files. The total length of the files' path is longer than Window command line limitation. The create process error is reported when compiling. This problem is temporarily solved by converting all STM32HAL files to a library file. But this error comes back soon as more files are added. I guess this issue is related to how the makefile works. How to fix it? Another thing, we use TGFX as the GUI engine. The generated files' path is fixed and long. Is there a way to change the path of the generating file? Thanks in advance.

Hi,we implemented your reference design coming from the STEVAL-ESC002V1 that is suitable for 2S to 6s battery.We found that the circuit didn't work under the 6.5Volt and we have the confirmation of this out of spec because STSPIN32F0A is working from 6.7V.So how can we use the circuit with the 2s conf? The minimum working voltage expected for 2s conf is at leas 6V.Can you help me to understand how to modify the project to support low minimum voltage (6v)?Can be possible to modify the firmware?

I would like to know how is the amplitude of the FFT calculated by the FP-IND-PREDMNT1 firmware related to the acceleration measured by the accelerometer found on the STEVAL-STWINKT1 board. It is expressed in an absolute value but I need to know the relation to the intensity of the vibration/acceleration.

Hello everyone, I'm using the evaluation board of the motor driver POWERSTEP01 with a nucleo board NUCLEO-F401-RE. As the powerstep01 works by writing in regsitres via SPI, I would like to know if there are one or more libraries that allow the functions to be used directly in my program ?Thank for your help 

Hello! I am honestly a newcomer in the field of embedded systems and I have some questions about a card I have been studying for a few days in class and within the company where I am working. I am enclosing the data sheet and I would like to know:-       What are the main advantages of this card (especially in comparison with an Arduino one)?-       What kind of projects could we carry out with this card?-       What does STM32Cube precisely mean?-       Could we connect an oscilloscope in order to observe the output signal by using an additional card?I truly thank you in advance for your answers.Sincerely,

So as the title. I'm going to design a motor drive which can drive two motor. (Seems like Odrive). Inorder to reduce the cost, I want to use the F103 as my MCU.如题所示，我想�?设计一款�?�路电机驱动。（有点类似开�?电机驱动Odrive）。为了节约�?本，我希望使用STM32F103作为我的MCU。​​First time I planned to use the MCSDK v4.3 to design my motor driver, and luckly it support F103 in dual motor application. (The chip choosed list showed )刚开始，我计划使用MCSDK v4.3去设计我的电机驱动，�?�常幸�?，MCSDK v4.3的dual motor模�?支�?F103（在它的芯片选择列表里�?�以找到F103）​​​After while, I got a new idea——"the newest MCSDK may have fewer bugs as the ST had improved it", so I dowloaded the newest version MCSDK v5.4.3 and found that it's dual motor model do not support F103 in dual motor application. (can't find F103 in chip choosed list )过了一会儿，我有了一个新的想法——“最新版本的MCSDK应该会有更少的错误，因为ST公�?��?�级了版本，完善了它�?​，所以我下载了最新的版本MCSDK v5.4.3，然�?��?�现它的dual motor模�?�?支�?F103。（在它的芯片选择列表里找�?到F103）​Then I'm puzzled.

Also is there any working tutorial regarding this discovery kit​

We use NUCLEO-H743ZI (old) and NUCLEO-H743ZI2 boards. The difference: ST-Link V2 vs. ST-Link V3.The same FW fails on newer ZI2 board with the ST-LINK V3 for the USB VCP UART transfer.Issue:I send files from terminal, or I use copy and paste of large strings in UART command line. It works fine on old ZI board (ST-LINK V2) but it fails on new ZI2 with ST-LINK V3.Even ST-Link V3 seems to work up to 10,000,000 bauds, if I use 1,8432,000 and I send large strings (from file or copy and paste in command line) which are larger as 255 characters - I lose many or even all characters.ST-Link V3 seems to have an issue with internal UART buffer management:I send a very large string - it depends how large: just the first few characters are received and forwarded to main MCU, or just the tail of the stringI did a test: if I send exactly 256 characters - the main MCU does not get any character!So, it looks to me:when sending with fast baud rate, seamlessly a large string, above 255 bytes the internal

hello​I have a question about the tutorial for the DFSDM excel file.https://www.st.com/content/ccc/resource/technical/document/technical_article/group0/1b/40/1d/43/1b/8d/47/65/dfsdm_tutorial/files/dfsdm_tutorial.xlsx/jcr:content/translations/en.dfsdm_tutorial.xlsx​In the "DFSDM configurator" sheet, what the "Sampling frequency" on B6 cell means? I am setting the clock frequency (2～3.25MHz for MEMS mic) and results similar sampling rate with actual data plot. I'd like to make sure I understand the parameter correctly.Thanks in advance.Masaru

I'm working on a project using TouchGFX and I need to add a tap of the entire display screen and that same screen also has a swipeContainer. And I'm having trouble solving this problem, because I can't get the swipe to work properly.Would anyone have an example that could help me?

Hi,We're planning to use LSM6DSOTR for shock and tilt detection in our IoT device. This device will be deployed in the field (on the surface of the ground) where cars can pass by it as well.The reason we choose this is IMU because its low power and is less costly compared to Bosch's sensor ( which is power efficient but costly).The question is, can we rely on the shock survivability of LSM6DSOTR? If not can you suggest a better alternate? Regards,Ukhan

Hello,I have a the following problem:I create a blank UI template for the STM32H7B3I DK with TouchGFX Designer 4.13.0.Then, I create a small UI consisting of 1 background box, 1 button, 1 image and 3 interactions. The behavior of the interactions is that when the button is pushed, interaction1 hides image 1, then interaction2 waits 1000ms and then interaction3 shows image1 again.This works basically. However, after some time (can be minutes, can be seconds), the UI hangs and the button is not responsive anymore. I debugged the application with STM32CubeIDE and found that the software hangs in the following function at line 8 "configASSERT(0);" :bool STM32TouchController::sampleTouch(int32_t& x, int32_t& y) { TS_State_t TS_State = { 0 };   /* This should never fail !! */ if (BSP_TS_GetState(0, &TS_State) != BSP_ERROR_NONE) { configASSERT(0); }   if (TS_State.TouchDetected) { x = TS_State.TouchX; y = TS_State.TouchY;   return true; }   return

Hi,I can not generate a simple project for Keil any more, The problem happened after I have upgraded my CubeMX from version 6.0 to 6.1.1How should I solve the problem? what's going on wrong?

Hi, I am developing a sigfox app using stm32WLE5JC. I am reading it using cube programmer and on sigfox tab the chip certificate reads all FFFFFFFFFF . I also tried to read the sigfox PAC and ID on the 0x0803 E500 but its al FFFF. I want to ask how can I retrieve the chip certificate?
