Hello, I a new with NUCLEO STM32H753ZI and trying the SBSFU examples (1 and 2 images). I can flash and launch the SBSFU but I can't load any user application (userapp.sfb)I use STM32 tools, either using Linux or Windows with the same result :I connect with a VCP using Teraterm (on Windows) or Minicom on Linux) with YMODEM protocol,The terminal display the SBSFU sequence, which is good and terminates by waiting for a user appli to be downloadedI Send the UserApp.sfb with (File->Transfer->Ymodem)AND the load remains stopped at the first block ....I have followed the guides given in the examples documentation (from readme files into project SBSFU V2.4.0), I have applied :The security configuration (Option Bytes set to Default "No Security")Serial configuration seems also OK

Hi,I'm working with the stm32mp157f-dk2 and with OpenSTLinux and I'm trying to create a GATT service for provisioning the wifi credentials.The problem is, according to https://wiki.st.com/stm32mpu/wiki/How_to_scan_BLE_devices I should be able to run the gatttool command. Unfurntently I'm not. I have already re-flashed the OpenSTLinux and I also have reprogrammed the kernel.I'm running the OpenSTLinux 5-4 20-11-12.What should I do? I have also tried the apt-get install command..Thanks,Fernando Fontes

Hi, we have designed a custom PCB with the LSM9DS1 as IMU, we are receiving data from the accel, mag, and gyro, in the case of the accel I think is easier to know if the measure is ok (we must get 1G in the z-axis), but how could we validate if the data of the magnetometer is correct? , is there any expected value? we are not using an ST microcontroller to interface with the sensor.Thanks

In CubeMX the name for the Automatic Retransmission of CAN-Messages is named: "NO-AUTOMATIC Retransmission"and is set to "DISABLE"When reading this I interpreted it as: Automatic Retransmission is done if set to DISABLEIn the generated code however the corresponding setting is:hcan1.Init.AutoRetransmission = DISABLE;Which leads to "no Automatic retransmission" and therefore to missing messages in case of high busload !!!Please correct the wording in STMCubeMX so other users are not falling into the same problem.BR GS

I am using GStreamer to stream live video from mjpeg cameras. For this I am using a pipeline which is roughly equivalent to this one:gst-launch-1.0 souphttpsrc is-live=true location=<camera_url> ! multipartdemux ! image/jpeg,framerate=0/1 ! jpegparse ! avdec_mjpeg ! videoconvert ! waylandsinkThis was working fine with OpenSTLinux 1.x, but with 2.x the video stutters or even freezes.Can someone help?Guillermo

Hi,I have one LSM6DSO32 with an Atmel SAMD21 Cortex M0. I use i2c to comunicate with the sensor. I use Arduino ide and Arduino librarys Wire for i2C communication. I've read the datasheet first of all I set some registers of my sensor I set gyro to 500° et accel to 8g//gyro 500° Wire.beginTransmission(DSO_ADDRESS); Wire.write(0x11); Wire.write(0x54); Wire.endTransmission();   //accel 8g Wire.beginTransmission(DSO_ADDRESS); Wire.write(0x10); Wire.write(0x58); Wire.endTransmission();DSO_ADDRESS is define by 0x6A. So I think everything works beceause if I try to read 0x11 after I set the value 0x54 I get this value :grinning_face: My problem comes when I want to read raw data from gyro and accel, I do that ://global variables int raw_temperature = 0; int gyro_raw[3] = {0, 0, 0}; int acc_raw[3] = {0, 0, 0};   //some codes here   void readSensor(){ Wire.beginTransmission(DSO_ADDRESS); Wire.write(0x20); Wire.endTransmission(); Wire.requestFrom(DSO_ADDRESS,

Posted on February 13, 2017 at 21:45So I'm DFU'ing. Successfully bootloading the device with the USB connections on PA11 and PA12 DFU is built into the STM32L476. Plodding along and loading my micro a few times with a few different compilations all good. THEN ---- POOF. One of them won't verify using DFU.So I try a file that just *DID* work with DFU.Yep - It worked again ??  WTH over.Dump the offending file into the device with STLink ---- works.....I repeat a few things, including inappropriate workplace language and its consistent. (The PROBLEM. Not the Language. I try to mix that up a lot. )So thinking I have the all singing and dancing IDE (Truestudio), I look for PAD out options. D A R N if I can find it.So I visit here again (I like it here) and I look here and findhttps://community.st.com/s/question/0D50X00009XkdwK/dfu-dfuse-problem-with-stm32l4-stm32l476vgReally?Get your HEX EDITOR (XVI32) out and add PADDING?The word LAME comes to

I have a 3 VL53L1X satel boards with me .I started testing it out and am facing some minor issues. I saw in the data sheet that I can program the Region of Interest. I am programming it in arduino. I was hoping if I can get a sample code with the programable ROI so i can get started. I was also hoping to know how i can change all of the device address and program it in ESP32 if arduino Nano cannot manage 3 I2C devices at once.Thank you so much in advance

I have some sliders in a scrollable container. I found that when I move the slider, the screen can still move up and down. How to temporarily lock the scroll function to avoid screen movement when the slider is triggered

Hi everyone,I am too new at STM, so I couldn't understand how to measure DC current. Can anyone help me to do my setting and code, please. I found out code for AC current and I decided to change some parts of this code, but I couldn't understand how should I do settings of pinout and configuration.

Circuit (programmer given by SAMTECH part) (zoom in to see):When I connect STLINK V3 Mini to program the STM32L4676RG MCU, it detects the chip without errors. However, when I try to flash, STLINK generates fail.text.Any idea what's happening?

I encountered this problem after trying to create a project from an existing ioc file. Afterwards all my endeavors failed as per the below screenshots:

Hello,I use two X-NUCLEO-S2868A2 board with blueNRG-2 with BlueNRG-1_2 DK 3.2.1 and S2-LP_DK_1.3.2I use following RF configuration :#define MODULATION_SELECT MOD_2GFSK_BT1 #define DATARATE 50000 #define FREQ_DEVIATION 25000 #define BANDWIDTH 100000 #define POWER_DBM 14 SRssiInit xSRssiInit = { .cRssiFlt = 14, .xRssiMode = RSSI_STATIC_MODE, .cRssiThreshdBm = RSSI_THR, }; S2LPRadioRssiInit(&xSRssiInit); S2LPRadioCsBlanking(S_ENABLE);RSSI_THR is -100 when I wait for a packet. I configured a s2lp gpio to change with Rx and Tx state : S2LP_GPIO_DIG_OUT_TX_RX_MODE = 0x90 in S2LP_Gpio.h. My issue is that i lose some packets. As you can see in the following screenshot, the sensor enter Rx state before gateway sends its ack. I use the antenna provided with the eval board, and the two boards are very close, few cm. Is it common to lost few packets considering this range ? or am i missing some parameters or functionnalities provided by s2lp ? 2 : Sometimes the app stuck in SpiRawTr

Hi,I'm developing a wearable smart device with nrf52832 and LIS3DH. In order to shutdown the MCU when the device is not worn I want to use the motion detection feature of the LIS3DH with an interrupt, so if the sensor doesn't fire an interrupt event for n minutes the MCU turns off (enters very low power mode).The users can set the interrupt threshold and the full-scale as configuration options.Here my current configurationCTRL_REG1 = 0x2F //10Hz, low power mode, ZXY enableCTRL_REG2 = 0x0 // No HP filterCTRL_REG3 = 0x40 //IA1 enableCTRL_REG4 = 0x00 //2g default value, configurable by userCTRL_REG5 = 0x00CTRL_REG6 = 0x0INT1_THS   = 0x3A // 58 * 16mg = 928 mgINT1_DURATION = 0x02 INT1_CFG  = 0x2A The first question is: In order to update the sensor's configuration according to user preferences, can the MCU write the INT1_THS and CTRL_REG4 registers, after the initial configuration, without physically rebooting the LIS3DH? Should I have to clean them

I am trying to get USB CDC working for the Nucleo-144 board. Where can I find an example application to run on the board?

Hello, I am an engineer working at Desird Arge Design. I had a problem with the STM32G031F6P6 processor. I think there is an error while selecting the timer channels in the STM32 Cubemx application. According to the datasheet description, TIM1; It includes 4 channels and 3 reverseers. When I check the list, I can confirm the information. However, when I use the STM32 Cubemx program for pin selection, the pins cannot be selected, the channel and inverting channels in the alternative pins conflict. Photos are attached. Would you help me with this topic?

Dera Sir/Madam,I chose STM32H750VBT6(LQFP-100 package-Revision Y-Max core clock=400MHz) for my project,based on my requirements .Everything was fine,until I perceived that: this magnificent MCU is not capable of toggling a GPIO pin faster than 30 ns(roughly estimation).I should emphasize that to reach this speed I had to ignore using HAL_GPIO_WritePin&HAL_GPIO_TogglePin and use GPIOx->BSRR directly in my program in a very very simple loop . If I can decrease this time to 15 ns(or less),I will reach my goal .I searched on the Internet and found a very useful discussion in this link:https://community.st.com/s/question/0D50X00009cdgGjSAI/stm32h7xx-fast-gpio-toggleIt seems that the H7 series has a limit to do so ,intrinsically.Here are my questions:1-If I use assembly language directly,can I reach this speed (15 ns)?2-If I use Revision V of this chip(LQFP-100 package),will it solve my problem(Considering internal HW differences with Revision Y,maybe)?3-Necessary settings w

I am running the STMCubeIDE 1.5.1 and would like to debug two boards simultaneously. One is a NUCLEO-H723ZG and the other is a NUCLEO-F303RT.  The applications for each are designed to communicate with each other through the SPI ports on each. So I would like to debug the communication protocol between the two boards. I can detect the unique serial numbers of each board under Debug Configurations > Debugger > ST-LINK S/N pull down menu after pressing the SCAN button. For the first debug session, I have checked Autostart local GDB server, but for the second I have checked Connect to remote GDB server instead because restarting the server upon launching the second session results an a GDB server error. What is the correct configuration for each debug session, provided that this is even possible?

I developed a board with the same carrier cancelation circuit as the ST25-EVAL board, but I'm having some different measures regarding the reception power. I would like to know if it is correct or if something is wrong.EVAL measurements :Ptx = 28.95dbmPrx = -8.671dbmMeasurements of my board:Ptx = 29.34dbmPrx = 5.23dbmI really don't know about there value are correct.Please, help me and Thanks!

Hi,I have an ST25R3911B-DISCO and have discovered that UART and I2C are not supported on the loaded firmware through searching Google on how to use the interfaces.I am wondering if there have been any updates in the last two years on this subject.If there have not been any updates, what is the best way in implementing UART or I2C in conjunction with my external board, the NUCLEO-L552ZE-Q?As a side note: I am aware there are Nucleo boards that have the ST25R3911B and I2C or that the ST25R3916 has I2C. I have the disco board and am planning on using this with my external processor in any way I can without modifying the board.

HelloI know that tilebox has a RTC module, so I realise it is psoible to get current time for generating timestamp for data. Is it posible to do it? Is there any implementation of that in given project examples? Thank you

Hi, I'm testing with the LIS3DHTR and I notice that the Z axis is noisier than the others axis. It doesn't matter the position of the accelerometer, always the Z axis is noisier. Why does happen?
