Dear STCommunity members,I’d like to test the MB1414 (ST25R3916_Discovery_DB) using the I2C interface. So, besides changing the Hardware of the MB1414 (by changing J200, J201, J202, J203, J204 and J205) I also need to update the Firmware of the MB1396 (ST25_Discovery_Mboard) to implement this interface.For a couple of days, I’ve been trying to compile the FW STSW-ST25R011 provided for the “ST25R3916 Discovery Kit�?, but unfortunately, without success. Probably I am committing a silly mistake since I am not really familiar with this environment.I am using the Atolic TrueStudio V9.3 to compile it, but after using the Import Wizard to import the “Existing Projects into Workspace�? and “Build Project�? I am getting the following error/warnings (see details attached: “Build_Log_fatal_error.txt�?):fatal error: stm32l4xx_hal.h: No such file or directory – despite the fact that its include folder is correctly added in the “include directories�? (see details attached: “Screenshot Path and Symbo

Once the STM8-SafeCLASSB SW package is integrated into our application the Periodic run time self tests are executed continuously but the STL_ClockFreqTest fails randomly. While running the entire application, that test normally fails after about an hour but some other times take 45min or even 4 hours.We are using the HSI as clock source.While running a debug session I can see that the measured LSI period is always above the threshold.We are using IAR for our project.In our application we also use Timers 3 and 5, SPI1 in slave mode with DMA, SPI2 in master mode, and EXTI.How to get full stability on this test? Is it possible that some of the mentioned peripherals could affect that test?Thanks in advance,Ricardo

Hello, We are interested in developing a product with this MCU but we are not sure when it will be available. Can you help me with some information? We are really early in the dev. cycle and we are not going to "mass produce"(hundreds of units or thousands at max.) until next year, but we need to know if this one will be available. Thanks a lot,Mihai

I want to create 2 analog output (DAC) on PA4 & PA5 pin. How to make DAC dual mode as instructed in refmanual? When I use template code and add 1 more DAC channel but no success.please help me how to make 2 DACs simultaneously.Thanksstatic void DAC_Ch1_EscalatorConfig(void) // DAC channel 1 { /*##-1- Initialize the DAC peripheral ######################################*/ if (HAL_DAC_Init(&DacHandle) != HAL_OK) { /* Initiliazation Error */ Error_Handler(); } /*##-1- DAC channel1 Configuration #########################################*/ sConfig.DAC_Trigger = DAC_TRIGGER_T6_TRGO; sConfig.DAC_OutputBuffer = DAC_OUTPUTBUFFER_ENABLE; if (HAL_DAC_ConfigChannel(&DacHandle, &sConfig, DACx_CHANNEL) != HAL_OK) { /* Channel configuration Error */ Error_Handler(); } /*##-2- Enable DAC Channel1 and associeted DMA #############################*/ //sine_val //if (HAL_DAC_Start_DMA(&DacHandle, DACx_CHANNEL, (uint32_t *)aEscalator8bit, 6, DAC_ALIGN_8B_R) != HA

For a long time I have been using the following setup:two STM32H7 eval boardsone gdbserver session for each STM32, with a different portremote debugging on the two STM32I just switched from STM32CubeIDE 1.0 to 1.10.1 and now I have this weird behaviour: It looks like the gdbserver now tries to connect to the two STM32 that are connected to the PC, even is I specified the STM32 serial number.I have to connect to the second board on port 61236, since the 61235 seems busy.Also my previous gdb command "monitor reset halt" seems to not be supported anymore.

helloabout 2 years ago, we used BLUENRG-GCSP.recently, we need to know about BLUENRG-GCSP bluetooth version.is BLUENRG-GCSP bluetooth4.0 or 4.2?Thanks.best regards

After attempting to code it up myself and after it didn't work attempted to verify using CubeMX.I have 2 questions:CubeMX does not give me the ability to select Alternate Function 2 on GPIOB pin 1 as input for TIM3_CH4, while Datasheet - STM32H750VB STM32H750ZB STM32H750IB STM32H750XB - 32-bit Arm® Cortex®-M7 480MHz MCUs, 128 Kbyte Flash, 1 Mbyte RAM, 46 com. and analog interfaces, crypto States PORTB alternate function does connect to TIM3_CH4 for AF2. Is this correct should TIM3 be able to do capture compare off PORTB_PIN1, or did I miss something?After doing HAL_TIM_IC_Start_DMA, I see the DMA copy TIM3->CCR4 to the destination (in memory) continuously even before any edge input comes in on PORTB_PIN1. Is additional synchronization needed or should this work as I expect after a __HAL_LINKDMA?

Hi, I want to use HRTIM to generate active low pulse of width 50ms. The functionality is to generate single 50ms pulse to enable external counter IC. Are there examples to configure HRTIM in single-shot mode.HRTIM kernel freq is 200MHz. Prescaler is 4=50MHz. This gives 20ns resolution on counter. For 16-bit counter, we can generate pulse width of 1.310ms. How to generate pulse width higher than 1.31ms?Thanks!

Hi,I am debugging my custom board where I soldered an LIS2DW12 accelerometer on it. I forgot to pull the reserved pin ( 7 ) to ground as suggested in the datasheet. This is how I connected it:This is how it should be connected:Is this required, that the accelerometer can work properly? I cant find it on my I2C bus and don't know if it is related to this little mistake or maybe another, most likely soldering issue.Edit: I2C is pulled up and decoupling capacitors are also there. Just on another section.Thank you

Hi,Every time I attempt to flash the BLE wireless stack to the chip or I try to perform a mass erase I receive the same error and the USB dongle disconnects.FYI - I have successfully been able to upgrade the FUS version with no issue:I attach the logs for both the Wireless stack fail and the chip mass erase fails.Not sure how to export the options byte (incase they are useful information here) so some guidance on that would be appreciate also.Thanks very much!

Hello!We have 2 identical custom PCB using STM32F446RE MCU, we encounter the following issues and we can't find out what is happening.I'll try to explain the best I can such problem, testing boards with simple LED blinking program:while (1) { HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_10); HAL_Delay(500); HAL_GPIO_TogglePin(GPIOA, GPIO_PIN_9); HAL_Delay(500); /* USER CODE END WHILE */   /* USER CODE BEGIN 3 */ }board 1: Program sometimes goes to HardFault with:HCLK Clock = 82 MhzHSI RC = 16 MhzProgram stops at HardFault_Handler with:HCLK Clock >= 83 MhzHSI RC = 16 MhzSame happens with HSE = 16 Mhzboard 2:Program sometimes goes to HardFault with:HCLK Clock = 75 MhzHSI RC = 16 MhzProgram stops at HardFault_Handler with:HCLK Clock >= 76 MhzHSI RC = 16 MhzHere with HSE it gives HAL_TIMEOUT error when calling SystemClock_Config(), with the following values when debugging inside HAL_RCC_OscConfig:tickstart = 101HAL_GetTick() -> uwTick freezes at 101External crystal is conn

It's cool that the schematics are available, and the assembly drawings are ok.but a full set of gerbers with all the traces and pads would be much better, esp. if it were in an EDA agnostic format.In lieu of that, what is the pitch of the J5 pads?

I have this library but I can't add in my project to communicate with the component SGTL5000. Thank you for your advices Regards

Please, Help

Hi there,I would like to execute some code in an interrupt handler when the pulse value for TIM16 is reached. But for some reason, none of the interrupts provided by HAL seem to trigger for this event.I have setup the timer using the configuration tool with the following:(TIM 16 running off an 8MHz clock)CH 1 - PWM Generation CH1Prescaler - 799ARR - 9999Mode - PWM mode 1Pulse - 2499I assigned pin PB8 to produce the PWM signal.To start the timer I have made the call:/* USER CODE BEGIN 2 */ HAL_TIM_PWM_Start_IT(&htim16, TIM_CHANNEL_1); /* USER CODE END 2 */I am using a scope to check that indeed there is a PWM signal on PB8 with a duty cycle of 25% and a period of 1s. As expected.I have placed LED toggling code inside the following interrupts:HAL_TIM_PeriodElapsedCallbackHAL_TIM_PeriodElapsedHalfCpltCallbackHAL_TIM_OC_DelayElapsedCallbackHAL_TIM_PWM_PulseFinishedCallbackHAL_TIM_PWM_PulseFinishedHalfCpltCallbackHAL_TIM_TriggerCallbackHAL_TIM_TriggerHalfCpltCallbackHAL_TIM_ErrorCallbac

Hi Team,I am using the stm32h745ziq as my development board to develop the FDCAN. To implement this I am not able to find any example for this FDCAN to this particular board.Can you please send me any FDCAN example program to this NUCLEO-STM32H745.Best Regardssm.

I am on a robotic forum where we have been studying using this VL53L5CX for robotic vision, mapping and SLAM for the last two months. We are on page 12 of this thread: "<link provided if requested and I'm permitted>"The problem we have run into concerns the distance readings we're getting out of it. The problem is explained in detail in the second half of this post "<link provided if requested and I'm permitted>" with pictures and previous posts to that thread give detailed output from the sensor.Since I am new to this forum and can't provide the links, I'll summarize the problem here:We have the sensor square-on to a wall 1000 mm away.The wall is house-painted whiteThe ambient lighting is very low (barely readable)Since the FoV angle from corner to corner is ~64 degrees, the corner distances should follow standard Trigonometry theory and be further away than the central pixels.Theory says, if the center is 1000 mm away, the distance to the center of all four corner pixels

I have a setting which can be manually or automatically adjusted/changed. A toggle button selection choses manual or automatic adjustment. Manual adjustment is done using a slider widget. When the toggle button is selected to automatic position, slider position will be adjusted programmatically based on auto adjusted value. In this case, I want slider to be disabled for manual adjustment i.e. slider head shouldn't move if attempted to slide manually. How can I achieve that?I tried by making a grey image appear on top of slider when automatic selection is made hoping that slider will not move because this grey image is on top layer now compared to slider. Moreover, the grey image gives slider disable appearance as well. But it did not work. Please let me know.

Hello,I want to apologize in advance for how long this post is. I wanted to provide as much information as I could so I can help you (the reader) get a better picture of what might be going on. Sorry.I am currently working on a project that uses a st25r3914 nfc chip to detect and interface with an NFCa tag. Also, I am using the pre-made RFAL for ST25R3911B library so I can get the chip up and running quickly. Unfortunately, this process has not been going so well. I am running into issues interfacing with a tag.Background InfoNFC Chip - ST25R3914NFC Lib - RFAL for ST25R3911BMCU - NXP S32K144OS: NXP freeRTOSI have successfully merged the pre-made library with the rest of my code and have populated the platform.h header file with all that is necessary. To test if the library is setup correctly, I am using the exampleRfalNfca.c example program that came with the documentation. I have verified that the system is initializing the RFAL lib correctly given that the return of the function rfal
