Hello!I have an ART_PI board with STM32H750XBHX MCU and W25Q64 FLASH IC on it.I want to make my own loader, but it doesn't work as it should.Running until the memcmp cycle, I look at the memory map. But the content is not good. There are values 00000000, 11111111, 22222222 instead of 00, 01, 02. Thus, memory comparison is not good.I can't find the error.I am attaching the files and the picture showing the memory map.Thanks for the help!

I have made a simple program flashing LED's from both cores and sending data between the two cores using a struct that resided on the same memory space for both.I used latest STM32CubeMX (Version: 6.9.2), STM32CubeIDE (Version: 1.14.1), and latest STLink firmware.It kept working reliable, until I added a few more peripherals to the project.After that I suddenly got programming errors, like:"No STM32 targets found"I needed to use STM32CubeProgrammer to erase the chip, where I only could connect using mode "Power down".After this, I could download (Download verified successfully), but the cores do not start anymore.After a few attempts, I get these errrors again:Starting server with the following options:Persistent Mode : DisabledLogging Level : 1Listen Port Number : 61234Status Refresh Delay : 15sVerbose Mode : DisabledSWD Debug : EnabledInitWhile : EnabledTarget no device foundError in initializing ST-LINK device.Reason: No device found on target. I tried several settings in STM32

I'm tring to detect tag infomation by ST25R95.Main board is STM32L476RG.I got the sample code from https://www.st.com/en/embedded-software/x-cube-nfc3.html.Example commands are descripted in the datasheet https://www.st.com/resource/en/datasheet/st25r95.pdf.However SPI commands that sample code actually sends are different.Do you have register map of ST25R95 or more detailed datasheet ? 

Hello people, i am making a project using STM32F407VG and i am using a timer that drives a laser. The problem is, when debugging STM is probably pulling couple of its pins to High state before i start F8 (between pressing the 'Debug' button and F8 to stop the program waiting at HAL_Init() function after i run the code it switches back to LOW state ) and messes up with my laser circuit. I want to know which pins go to High state and why, and see if i can control it i really have to deny it pulling to high state. Thanks for the help. Have a great day !  

so my project consists of : exploiting the serial communication to send the conversion data from ADC1 Channel 1 in ASCII format and considering a verification scenario for the program's functionality.about the verification scenario i visualize it in "putty" and it is right (i'm using a potentiometer like an analog input to my ADC ) (i also used a multimeter to know that adc is reading the input correctly)  and i get logique outputs is there any other thing i need to check that UART communication is set perfectly any verification scenario i should also implement??? 

when i downloaded the code from cube ide and then try to visualize it with putty it works perfectly but when i moved the project to keil and then download it from there i didn't got the same result ascii is stuck at number 8 and it's not showing the write output related to volatge what should i do ?? , do i need some new configurations on keil cause i'm not getting any error neither warnings !!!!   here's the function of to convert an integer to ascii :char* shift_digits(int input_integer) {// Convert the integer to a stringchar input_str[20]; // Assuming a reasonable maximum length for the stringsprintf(input_str, "%d", input_integer);// Allocate memory for the result stringchar* result_str = malloc(3 * strlen(input_str)); // Each digit is shifted by 3 characters, and 2 extra characters for spaces and null terminator// Shift each digit by +48 and join them with spacesint index = 0;for (int i = 0; i < strlen(input_str); i++) {int shifted_digit = input_str[i] ;index +=

I have two STM32 micros connected via CAN transceivers.  The sending unit is transmitting without issue, as evidenced by measuring both the CANH/CANL bus wires, as well as the CAN_RX/CAN_TX logical wires on the transmitter.  I did have to slow the bus down significantly due to high capacitance (troubleshooting at 20 kbps; hope to increase speed once I get the situation figured out).  I am using classic 11-bit identifiers, subdivided into a 7-bit message type and a 4-bit node ID.I can see the ACK bit on the CAN wire, so I know the receiver in the chip is correctly identifying the frame.  However, the receiver's two FDCAN interrupts never fire.  I have both set the non-matching 11-bit identifier action to FDCAN_ACCEPT_IN_RX_FIFO0 as well as set a id/mask filter with a mask of 0, as well as a filter set up the way I would intend for my application.  I will now let the code speak for itself: First, the MX-generated initializer is called: static void

I'm trying to use SPI to communicate with a display (BT817) and whenever it tries to send data, the while (!LL_SPI_IsActiveFlag_RXNE(EVE_SPI)) {} never returns.  I've attached my CUBE IDE project.  Could anyone possibly give some guidance?  Am I missing a setting, have the clock misconfigured?  The board has a STM32F030R8Tx.Kindest regards

Is there an example for the x-cube-azrtos-l4 usbx stack showing how to implement the additional string descriptions and GET_OS_FEATURE_DESCRIPTOR features to allow an HID device to appear as WinUSB?

Hello all,I'm currently working on a project to detect multiple objects on a grid. I plan to put NFC tags on each object and use only one reader to detect all of them. One of the solution is to have one reader's antenna per cells.Is it possible for me to use multiplexers at the output of the matching circuit in single ended version of the ST25R3911B reader? Will the ST25R3911B reader be able to detect the signal coming from multiple antennas?Thanks and best regardsAzzam Zahra

I am developing an application for the STM32U575, and am currently testing on the Nucleo-U575ZI-Q. As per the reference manual (Rev. 4) Section 10.9 PWR Interrupts, Table 110 Note 1: "The PWR_S3WU interrupt is generated only when the device is in Stop 3 mode (not applicable in Run, Sleep, Stop 0, Stop 1, and Stop 2 modes)."However this is not the behaviour I am observing. I have found that the PWR_S3WU interrupt is generated whenever the Stop 3 mode is configured as the Deep Sleep Mode (i.e. PWR_CR1 LPMS[2:0] = 0b011), even if the stop mode is never entered.Can I please get confirmation what behaviour I can expect, for the nucleo and my target hardware (STM32U575VIT6Q)

Hii'm just sitting and messing with a few lora boards.I find that nucleo-WL55JC1 has approx 10dbm RSSI better than seeed LoRa-E5, and that nucleo-WL55JC1 also transmits with a more powerful signal, what is your experience ??with best regards

Hello,I would like to enable the dragged of the circle only in the horizontal direction for a customized container on which I only have a circle. I would also need to limit the left and right "stop" when dragging. I set up draggable and I can move the circle freely. Can you advise? Can I find a exaample somewhere?Thank youJN

Hi there!I'm experiencing a new trouble: trying to program a simple flash Word it results in an hard fault; moreover, also trying to read the same area gives an hard fault.Debugging the application I discovered that the HAL_FLASH_Unlock function fails.Since I already seen sutch code work, it's quite strange to me! b08t InitFLASHwrite(void) { /*.-.-.| Local variables: |.-.-.*/ b08t bIsError = FALSE; // Output error indication HAL_StatusTypeDef enuUnlock = HAL_FLASH_Unlock(); // Unlock state /*.-.-.| Execution: |.-.-.*/ // Unlock FLASH memory... if(enuUnlock == HAL_OK) { // No errors: __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_EOP | FLASH_FLAG_OPERR | FLASH_FLAG_WRPERR | FLASH_FLAG_PGSERR | FLASH_FLAG_WRPERR); // Clear pending flags (if any) // Needed after an update retry otherwise flash erase is not executed __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_ALL_ERRORS_BANK1); __HAL_FLASH_CLEAR_FLAG(FLASH_FLAG_ALL_ERRORS_BANK2); } else { bIsError = TRUE; // Else in

Hello members,I have problem with functionality of DMA data stream for ADC3 peripheral. I have H743ZIT controller. ADC1 with DMA is fully and properly working for each channel. I have placed ADC data array to RAM_D2 section for ADC1. For ADC3 I have used RAM_D3 section which should be proper for BDMA implementation. ADC3 seems to work good - because I see changes in DR register, but DMA transfer error occur immediately after HAL_DMA_IRQHandler is executing. Exactly this case is true:"else if (((tmpisr_bdma & (BDMA_FLAG_TE0 << (hdma->StreamIndex & 0x1FU))) != 0U) && ((ccr_reg & BDMA_CCR_TEIE) != 0U))"It leads to HAL_DMA_ERROR_TE error code. In attachment you can see some files with config. STM32CubeIDEVersion: 1.14.0Build: 19471_20231121_1200 (UTC) STM32CubeMX - STM32 Device Configuration ToolVersion: 6.10.0-RC9Build: 20231120-2037 (UTC)  Thank you very much for help.   

Watching some videos online about FFT and trying to use (in STM32CubeIDE) the arm_rfft_fast_f32 function of the arm_math.h DSP library, it is not clear to me why the buffer output produced by that function is N/2 long and not NIs it something related to Shannon's theorem? To the symmetry of the spectrum? (i.e. is it symmetrical around the origin).You are welcome to share external links if there are detailed explanations that I did not see during my internet search.

Hi, do you have any suggestion of a mechanical test bench setup to verify (/evaluate) the chosen accelerometer parameters? I'm working with an LIS2DW12, but I expect my question applies to all accelerometers:I have configured the accelerometer to send me an interrupt as a certain threshold condition is fulfilled (INT1_WU enabled).I use my device in a situation in which, in my opinion, the threshold condition is fulfilled. Nonetheless, the accelerometer does not wake up. Note, the accelerometer can wake up, but only in the event of a stronger acceleration. In other words there is no electrical/mechanical problem with the device itself.Therefore, I see several possible culpritseither the acceleration in the real world situation is below my threshold (in which case I would have to lower the threshold(*)); and/orthe above-threshold value happens too shortly, so that the accelerometer didn't have time to react (a higher ODR might work(*)?); and/orthe housing(s) in which I've teste

We have a new design were we have multiple VN5050AJ high side drivers. We have connected all current sense pins together and want to enable just one current sense per time to save analog inputs. Now it seems that the CS_DIS pin is ignored and the chip always drives the correct current out of the Current_Sense pin and ignoring the CS_DIS. Levels should be fine as we have 0 Volts and 3.3V for the CS_DIS input (Pin 5) which is way above the limits from the Datasheet. 0.9 and 2.1V.  Thanks

Hi,I'm looking at customising the circle progress.I was able to add this as the background image and added a single dot as the image to rotate.Any idea on how to rotate the dots and make it disappear? 

I want to add custom wave forms like square, sine and etc, so how I could achieve this easily?

I have a source folder named components where each subfolder has a .c and a .h file, see screenshot below.I am trying to include these files, but they cannot be found. So far, I know that I should add the relative path and so I did. (I also tried to replace the ../ with the ./ in the #include). How to solve?  

Hi,I was using an STM32MP157F-EV1 evaluation kit and followed the instructions mentioned in https://wiki.st.com/stm32mpu/wiki/X-LINUX-AI_Starter_package#Configure_the_AI_OpenSTLinux_package_repository and installed the AI OpenSTLinux package. I then proceeded to X-Linux-AI sample AI applications. The demos appeared on the onboard display on the evaluation kit.I tried opening the applications using the touch interface as well as the command line. Example https://wiki.stmicroelectronics.cn/stm32mpu/wiki/TFLite_Cpp_object_detectionIn both cases the application loads but there is not input from the onboard camera.I tried copying some test images onto the testdata folder and running the application to detect the static images. This works fine.The demo camera app on the demo launcher works fine as well. But none of the AI demo applications are able to use the stream from the camera.Below are a few things I tried.root@stm32mp1:~# /usr/local/demo-ai/computer-vision/tflite-object-detection/bin/
