Solved

Hi everyone,I use a custom stm32f0 board and i try to catch data coming from can bus and answer it back to can bus line. In the begining my program works good but after a couple of minutes mcu stucks in reset(i am not sure of the cause is from software or hardware but 'nrst' pin pulling down to 800mV-1.2V). i need power off and wait 15-30 min, for a reprograming. swd connection errors; 'couldn't be able to stop cortex-m device! Please check the jtag cable'in my design i made some mistakes such as; nrst pin isn't connected to pull up resistor and pull down capacitor. if i change the nrst pin pull up with 10k(or less) and pull down with 100nF will my problem solve? there is my custom design and code.

Hello,Concerning the AN3359, what is the unit of the figure 2 ?Thanks.

Hey,I´m confused why i can not use Pin PD2 on Cube MX on the Nucleo Board L433RC even though it should actually exist because it exist when you select another STM32L433.Without that Pin, i can´t use SDMMC. If i select for example the STM32L433RCTx, there is the Pin PD2. But if i try to use it with the Nucleo it wont work.Any suggestions?

Hello,I am configuring ScrollWheel on touchgfx.In order to select an option, I need to click on ScrollWheel.In order to browse all the options, I need to drag on ScrollWheel. So, I need both handleClickEvent() and handleDragEvent(). I also need to differentiate between a Click and a Drag action.But, upon drag action, my program control goes in handleClickEvent() only. It never reaches handleDragEvent() function.Please suggest how can I detect Drag event?

Posted on April 03, 2018 at 12:29Hello,I am working with CR95HF IC. I have some questions regarding it.1. How much read range can be achieved with how much Henry of antenna inductance. Can any one Please suggest.?2. Is it required that Antenna inductance and Tag antenna inductance should be same for good read range.?3. Does it support multi tag detection at same time ? If yes then how many tags at a time?Thanks & Regards,Margisha Dave

STM32CubeWB is the firmware package of the stm32wb series.when i clicked the Get Software Button，the page jumped to the home page.I have logged in to my ST Account.

I've configured bank1 FSMC to drive a LCD using CubeMx copying the various example code. I've set up FSMC-A18 to be the pin driving the Control/Data selection on the LCD. All data lines + OE and WR work perfectly but A18 sits continuously low whether I write to REG or RAM. I can't see in the examples how this is supposed to work as I can't find any code that sets whether it should be high for data/low for control or visa versa. The pin itself works fine if I drive it direct. This is my first use of FSMC and I'm clearly missing something - help appreciatedI can attach code and CubeMX images if that helps diagnose

Hi all, I have a C++ project running fine on the STM32H7 EVAL board that I need to port to an STM32H7 Nucleo board, because it closer resembles the final hardware I will be using. I generated a Nucleo project using CubeMX and added all the things I needed (Including FreeRTOS). I then converted the C project to a C++ project in True studio, and added all the source files, include directories, compiler flags, and linker flags. The EVAL project linker script places all user data in RAMD1 because it has the size required to hold the 128K stack required by the RTOS. When I alter the linker file of the Nucleo project for the same reason, the program gets stuck during startup, at the point of loading the c++ global constructors :/* Call static constructors */ bl __libc_init_array (When I say 'gets stuck' I mean the debugger can't step over or into this line. I believe the program jumps to an undefined interrupt with an infinite loop for debugging.)If I reduce the stack size of the RTOS

Hello,I appears that STD25N10 is designed to a replacement for the STD15NF10. Do you confirm?Do you have any comparisons or recommendations about external gate resistors when this device is used in a three phase inverter application? NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hi!I want use an VL53L1X sensor for our project. I "ported" to original ST api to TI chip and TIRTOS. But I cant measure any distance. Now I just want to try the sensor, so I using "polling" method. But when I call a GetMeasurementDataReady function, the "data_ready" variable not set. I am almost sure not problem with porting, because I can get the device Info. After I call GetDeviceInfo the struct has contains:name : Vl53L1 cut 1.1type: VL53L1product ID: 00000ProductType: 239 (0xef)RevMajor: 1RevMinot: 15 (0x0f)The drivers info is here:revision 1885major 2minor 3build 3My code is here: VL53L1_Error status; VL53L1_RangingMeasurementData_t ranging; // dev=&pdev;   uint8_t data_ready = 0;   init_i2c(); // dev.I2cDevAddr=0x52; dev.I2cDevAddr = 0x29;   PIN_setOutputValue(ledPinHandle, SENSOR_SHUTDOWN, SENSOR_OFF); Task_sleep(100000); PIN_setOutputValue(ledPinHandle, SENSOR_SHUTDOWN, SENSOR_ON); Task_sleep(100000);   status = VL53L1_WaitDeviceBooted(&d

I generated my code (HAR model) and could validate the process with random numbers. But, when I want to validate with my custom data, there is an ''VALIDATION FAILED'' error. please find the attachment contain the error and my csv test file. The file contain 3-axis of data for jogging and contain 62 rows of samples. please let me know what the problem is.Also I will appreciate if you upload a test csv file for custom data validation of HAR for better understanding. Thank you in advance

Hi,I recently purchased STM32L072 MCU and designed my own PCB which has the HSE and LSE crystals. I found a weird problem when I power the MCU.-Once I connect the power, it consumes 10 mA. I programmed the MCU, without any issue. But, I found that the code never executes. Even in debug mode, the code does not start even the first function. From what i found, the system clock source is not working and it consumes 10 mA.-When I quickly connect and disconnect the power, at some point the clocking system starts working and then the MCU starts executing functions. When it is working, it consumes 1-2 mA which makes sense. At every power ON action I have to do the same.-I put a probe of oscilloscope on a pin of crystal, it is a proof. There is no signal on this pin when it consumes 10mA, while I see a perfect 8 MHz signal when it is running and consumes 1-2 mA.-I tried the internal HSI as well, and the problem is similar.Can you help to understand why this issue exists? I tried two chips and

Hi,I'm waiting for 1.4.0 due to lack of LL drivers in 1.3.0.According to the thread linked below, 1.4.0 was planned "beginning of 18Q4", is there a new roadmap or release date when we can expect it?Currently it's holding us back from using the H7 at all.Best regards, Patrickhttps://community.st.com/s/question/0D50X00009XkbYxSAJ/stm32cubeh7-missing-the-ll-lowlayer-api

I am trying to add a kernel module for USB serial devices following: https://askubuntu.com/questions/168279/how-do-i-build-a-single-in-tree-kernel-moduleIn order to build just the module, not a completely new kernel , I would need the Module.symvers file. Any idea where to find it?

I didn't find “dynamic_bitmap_example“ in TouchGFX

Hello, all!For some time now I have been trying to come up with a solution to connect 2 cameras of 480X640 resolution and several peripherals to a low-power MCU. I keep hitting a wall, because it seems that this endeavor is not suitable for an MCU - the large RAM required to host 600K image, the fact that I can't connect 2 USB / DCMI cameras and need several MCUs that defeat the purpose, the fact that having a DCMI, an FSC and several peripherals on the same MCU, that is also, low-power, is unheard of..So, I'm trying my luck with an MPU:does ST offer a low-power MPU that has a large RAM, >100 IOs, and most importantly - can interface 2 USB cameras?Is there a tool like MCU FInder for MPUs?Are there guides for getting strated with ST MPUs?Is it possible to perform an Over The Air Update with an ST MPU?Thanks!** Partial answers will be much appreciated as well. Just starting off with the MPU direction, and want to understand if it suits my needs and how challenging it would be.

I want to use Nucleo-L476RG to generate pwm output. but the problem is i can't use TIM2. TIM5 is ok. i use PA1 to generate pwm, when set PA1 as TIM2 CH2, it doesn't work. but when i use it as TIM5 CH2. it works. How can this be happened? is there any difference between TIM2 and TIM5? can someone help me? thanks in advance.Initialize code is below:   TIM_HandleTypeDef led_pwm_tim_handle; TIM_OC_InitTypeDef led_pwm_oc_init; led_pwm_tim_handle.Instance = TIM5; // tim2 not work led_pwm_tim_handle.Init.Prescaler = 80-1; led_pwm_tim_handle.Init.CounterMode = TIM_COUNTERMODE_UP; led_pwm_tim_handle.Init.Period = 666-1; led_pwm_tim_handle.Init.ClockDivision = TIM_CLOCKDIVISION_DIV2; led_pwm_tim_handle.Init.RepetitionCounter = 0; led_pwm_tim_handle.Init.AutoReloadPreload = ENABLE; HAL_TIM_PWM_Init(&led_pwm_tim_handle);   led_pwm_oc_init.Pulse = 332; led_pwm_oc_init.OCMode = TIM_OCMODE_PWM1; led_pwm_oc_init.OCPolarity = TIM_OCPOLARITY_HIGH; led_pwm_oc_init.OCNPolarity

Hello,I have a problem with STM32CUBEMX v5.1.0. I cannot download a new embedded software package, I receive an error that package is not available. I have that package downloaded and I tried to load this in cubemx using "from local" option and again I received an error like that: "Problem during Unzip the file"I tried with older software packages and I got the same errors.
