I am interested to know the key differences between the VL6180 and VL6180X ToF sensors.I understand that the VL6180 has no ALS and also it appears to operate over a longer range.Is it as accurate in the 0-100mm range as the VL6180X?Thank you

Hello,I've got a STM32H745BI on custom board and I cannot get it working. The program always jumps to the error handler at while((__HAL_RCC_GET_FLAG(RCC_FLAG_D2CKRDY) != RESET) && (timeout-- > 0)); if ( timeout < 0 ) { Error_Handler(); }I've found in the reference manual that D2CKRDY is D2 domain clocks ready flag, so it's probably some sort of clock issue. I'm using the internal oscillator. What could be wrong? Thanks :)

In the pack FP-AUD-BVLINKWB1, BLE audio streaming example provided with Opus codec, will you be also providing similar example using new LE audio standard with LC3 codec?

We would like to use the ST25RU3993 in device side usage as described in the ST UHF library manual. Therefore we installed the STSW-ST25RU-SDK Firmware and build it with the TRUE STUDIO. Unfortunatly the given function docycleinventory does not show the tags which are close to the Antenna.We set the programm to use the internal PA and the antenna 1. The frequencyprofile is europe and continious modulation is also active. We log the cycleData variable to know if the inventory found some tags. Could you please tell us what our mistake is, or if there is a missunderstanding, on what this function does?Is there a better way to do inventory etc. than wive the given do cyclicinventory? We found out that we could use the build in Stuhfl_evalApi functions. Unfortunatly we were not able to find good information on how to use them. If we trie them with the init values, the firmware jumps in to an infinit loop. Some examples on how to use the Stuhfl_evalApi functions would be great. And the given

Dear Community,can someone advice a min 8Mbit psram for the STM32F479?I only find some who has address pins up to A20 but the uc has only up to 16 or did I missunterstand something?best regards

Dear ST member,I attached a piece of my schematics design. Can LIS2DH works with pins 3 (SA0) and 4 (CS) not connected?Regards

Hey, I'm trying to get some temperature readings from LM35 sensor and I'm using "blue pill" for this little project and of course ADC. The problem is that I am getting wrong readings, approximately half of the real value. I know that the sensor is good because I tested it with arduino nano and well it gave me right values. void ADC(){ error= HAL_ADC_Start(&hadc1); if(error!=HAL_OK) { i=1; } error=HAL_ADC_PollForConversion(&hadc1,1); if(error!=HAL_OK) { i=2; } i=3; Adc_Value = HAL_ADC_GetValue(&hadc1); Reiksme=(Adc_Value*3.3)/(4096*0.01);HAL_Delay(1000);}here is my little function to get those values. Any ideas why it doesn't work on this mcu?

HI,I am using a stm32l0 series, I want to do a dual bank upgrade but I don't how to enable the dual bank mode in IDE. I found some document show me some key word like "nDBANK", DBANK, but i have no idea how to setup.

Recently, i was trying to integrate the USB-PD library from ST with the support for the STUSB1602 IC that we have on our custom hardware. I found out that the precompiled library from ST supports only the Cortex M0, M33 and M4 MCU's.... Why is that? I really need help for integration of that lib with Cortex M7 to be able to make my custom hardware charge faster on the USB-C. Thanks,

Hi guys!I am trying to flash code via the USB-DFU but every time I tied BOOT0 to GND and connect a MicroUSB from the STM32 chip to the computer it does not detect it at all. I have no idea what's going on here?I am assuming its because I dont have VDD33USB Connected ? Otherwise I am out of ideas. I installed all needed drivers and what not.Any info would be helpful as this is my first time trying to use the bootloader of the STM32. Here's the schematic of the STM32 and what pins I used.

Hi, we are currently bring up our custom STM32MP157 Board. We get in any constellation a "DDR addr bus test: can't access memory @ 0xc000004"We think that our crystal is correctly running at 24 Mhz because we connecting over USB to the Board. Also the Voltages is correctly. We use the same DDR Chip, that is on the DK2 ( Micron ), with the same settings. We run a little bit out of ideas how to handle this. We also got DDR errors in Uboot SPL.Have you any hints beyond the "Bring up" Guide?Best regards

Hello,I am trying to get a BR2804-1700 kV motor running utilizing a B-G431B-ESC1 board. Till now I managed to get the motor starting to rev-up, but in the middle/at the end of the rev-up process I receive a "speed feedback"-error in the Motor Control Dashboard. Running the motor from Motor Profiler works without any problem.I have already applied two fixes from the forum:To fix ADC2 warning when generating Code, which did work https://community.st.com/s/question/0D53W00000JM31XSAT/adc2-warning-when-generating-project-for-bg431besc1And I tried following fix, which had no effect eighter positive nor negative: https://community.st.com/s/question/0D53W00000HwV8RSAV/bg431besc1-motor-profiler-not-working-moderator-note-this-post-contains-now-a-bugfix-patch-on-provided-exampleI have also tried to adapt the parameters as suggested in the STM32 PMSM FOC SDKFrequently-asked questions (FAQ) document, e.g. decreasing the C2 gain, but it still does not work.Is there any fix I missed?If no

Hello,can I use the NUCLEO-F303K8 dev board as ST-link SWD programmer for external MCU? There is a SWD connector on the board (not populated), but it seems that it is for input programming rather than output. Am I right?Link:https://www.st.com/content/st_com/en/products/evaluation-tools/product-evaluation-tools/mcu-mpu-eval-tools/stm32-mcu-mpu-eval-tools/stm32-nucleo-boards/nucleo-f303k8.html#overview

Hello,So I bought a B-L4S5I-IOT01A with the intention to use it as a MQTT device to send and receive data. My problem is that i cannot communicate with the on board Wi-Fi chip "STM32_IWIN_WIFI_V2". Here's what I did :1- I create a project with STM32CubeMX for STM32CubeIDE, and added FreeRTOS (because I plant to use it in my finished project), and initialized all the peripherals to default. And made sure that UART3 (the Wi-Fi chip com port) was configured with the proper default parameters.2- Then I added a library called "STM32_IWIN_WIFI_V2" that I found on the Wi-Fi chip manufacturer web site. It's basically a UART wrapper to help interface with the chip. Originally this library is meant for STM32F4, but since it only called HAL_UART so I went ahead and modified #include for STM32L4.3 - I used a demo program supposed to connect to a Wi-Fi network and post messages about it on the StLink uart port.4- It didn't work... The MCU could not established UART communication with Wi-Fi chip. 5-

Hi,I just upgraded my STM32CubeProgrammer to 2.7 and now getting error that can't find tf-a-stm32mp157c-dk2-serialboot.stm32.I tried this on three other images that have worked in past, get same error.tf-a-stm32mp157c-dk2-serialboot.stm32 is not found on file system for any of these images.Specifics:target: stm32mp157c-dk2host: Windows 10Images built on WSL.Unfortunately I deleted 2.4 before installing 2.7, also tried 2.6, 2.5 and get same problem.Have any suggestions ?

According to the schematics of the STM32F746G-DISC Board, the Camera_CLK pin in the Camera Connector need to sourced from OSC_24M, I couldn't find form where. There seems no internally used pins for this as for others in the schematics.Someone please help me out with this.

I'm using the dynamic graph to represent a small dataset. The data is acquired all at once through a back-end process, leaving me with an array of around 1000 datapoints. Once acquisition is complete, I use the following code to refresh the graph.graphWidget.clear(); for (int i = 0; i < size; i++) { graphWidget.addDataPoint(yValues[i]); } graphWidget.invalidate();This works sort-of, however the X value labels also increment by size. I want them to restart from 0. I assumed .clear() would do this, but apparently not. How can I reset the graph and labels back to a fully empty state, such that I can explicitly get labels starting from 0 again? Attached photo shows current (undesirable) behavior.Solved. Thanks @Vladimir​ Open AbstractDataGraph.hpp and scroll down to the AbstractDataGraphWithY class definition, around line 995. Add the following method to the HPP file.void dataCounterReset() { dataCounter = 0; }In your View code, call the method to reset the x-axis labels.

I am currently using Linux and compiling my project using my own Makefile, with libraries generated via STM32CubeMX from my Windows machine. I am trying to use CMSIS's arm_mat_mult_f32() function but it is not working. I suspect I am passing the wrong compilation flag, but am not sure what I am doing wrong.I am using STM32F7508-DISCO board. Below are my (what I think are relevant) compilation flags..-mthumb -mfpu=fpv5-sp-d16 -mfloat-abi=softfp -mcpu=cortex-m7 -DSTM32F750xx -DUSE_HAL_DRIVER -DARM_MATH_CM7 -D__FPU_PRESENT=1 (-DARM_MATH_DSP)I had to add -DARM_MATH_CM7 and -D__FPU_PRESENT=1 to make it compile, but maybe I am adding something I shouldn't be adding. I tried both with and without -DARM_MATH_DSP but it does not work.Especally, I go into hardfault handler while running arm_mat_mult_f32(), especially when (I think) running this inst: vldr s14, [r4, #-12]I am not sure if I am passing the wrong flags, and if so, what is the right flag for my board. (1) what is the right flag for m

lsm6dso sensor generates significant motion interrupt when a change in user location is detected. It generates an interrupt when the difference between the number of steps counted from its initialization/reset is higher than 10 steps. So it uses step counter. I will use this sensor on car. So I can not take interrupt, when the car changes location. Since there is not any steps. Is there any way to detect significant motion interrupt without using step counter in lsm6dso sensor ?

Hello guys :waving_hand:​I am having a STM32F401CDU6TR on a custom board and I am not able to run it at 84 MHz SYSCLK. The source is an external 8 MHz crystal with two 22pF caps as seen here:​I created the project in CubeMX as a Makefile project. I only use CubeMX for configuring the GPIOs as well as the clock. The actual code is written and flashed via VSCode. Works great so far.​Here is my current 84 MHz clock configuration in CubeMX:And this is my RCC configuration:​When I flash this code I always end up in a HardFault_Handler before the SystemClock_Config(); function returns. ​/** * @brief System Clock Configuration * @retval None */ void SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0};   /** Configure the main internal regulator output voltage */ __HAL_RCC_PWR_CLK_ENABLE(); __HAL_PWR_VOLTAGESCALING_CONFIG(PWR_REGULATOR_VOLTAGE_SCALE3); /** Initializes the RCC Oscillators according to the specified par

Hi all,I am testing product samples fitted with STM32F412RET6 which has a temperature operating range of -40°C +85°C.On some samples tested inside a climate chamber, the MCU unexpectedly reset due to cold temperature within operating range (e.g. -5°C).I have reproduced this behavior with a freeze spray and used the debugger to see what really happens.When abruptly cooled with the spray, some MCUs issue a hard fault. Those are the same that fail inside the chamber.The faults don't seem to originate from a certain spot in the code.It really seems that the chips are involved as I have unsoldered, resoldered and switched two chips (one good and one bad) and the problem followed the chip.The firmware is the same as the chip revision.Did you ever experience something similar ?

VL53L1_PerformOffsetCalibration(Dev, 140, 17 << 16)From digging in the code it looks like CalReflectancePerCent is fixpoint1616 and CalDistanceMilliMeter is an int32. For example is this the correct format to calibrate with a 17% Grey card at 140mm?
