Solved

HiI was wondering if there are any examples for using the Sensor Fusion Low Power Algorithm inside a LSM6DSV16X. I would like to retrieve the current Heading, Pitch and Roll information. Alternatively I'd also be happy with an example explaining how to get the Quaternion values from the SFLP. Anything regarding the SFLP would be nice. The examples do not outline any of the SFLP features (at least I was unable to find anything except the calls for directly manipulating the registers).

Hi,I'm not able to use the GUI (W7). The DFU driver is not detected and the guidelines to fix it are not clear.At page 5/32 the UM2517 claims:Enter “C:\Program Files (x86)\STMicroelectronics\ST25R3916_Discovery_GUI\Driver�? and install it.But the \Driver folder does not exist at all...Where's this driver? Please, could anyone clarify this?On the other hand the Method 2: ST-Link on next page does not work neither. Any hint?thanks in advance,gaston

Posted on July 27, 2017 at 15:43Hello,I am trying to set up CUBEMX so that it can support LCD display for the STM32F469i-Discovery board.Unfortunately I had no luck in making the correct configurations to enable the LCD display or find an example project for the STM32 ac6 or maybe a .ioc file with LCD setings.Is there anyone familiar with LCD on STM32F469i?What are the correct configurations?Thank you!#lcd #ltdc #stm32f469-discovery #cubemx #ac6 #ioc

What are the 144 pin MCU s available

Starting from this video (https://www.youtube.com/watch?v=CGUC1wqSLCE) I'm trying to write my bootloader for DFU from an USB stick. The code works but I would like to tweak it such that:if at boot an USB stick is detected, than start the update, otherwise jump to application (done and it works)at the end of the update, jump to the application (this does not work)I got it work the second point by adding a delay to let me remove the USB stick. But if the USB stick is still plugged in, then the "jump to application part does not work.I suspect that this is related some kind of USB peripheral initialization.Here is the zip of the project.

Hello everybody, We hope you are doing well.we planned to use ST25R95 chip to create a smart card reader that can communicate with all smart cards and java cards (MIFARE and NFC). we read in ST25R95 datasheet that this chip does not support write action in all standards(ISO/IEC). We know we can use PN512 chip that fulfills all needs we have.Does anyone know PN512 can be replaced by ST25R95?Can we have full read/write access to all tags MIFARE and NFC mode in all standards(ISO/IEC) by using ST25R95?Thanks in advance.Best regards.

Hi everyone,I have just discovered that I have multiple errors when I try to read more than 30 blocks, rfalNfcvPollerReadMultipleBlocks() function depending on the number of blocks I try to read.Firstly, I want you to talk about the TAG I am reading: - It is a ST25TV02KC NFC type5 - ISO/IEC 15693 (NFCV) TAG from ST - It has 320 bytes of memory and 4 bytes block-size.- With the Android app ST25 I can read all the blocks correctlyThe behavior I am seeing is the next:- I can read successfully from 1 to 30 blocks. - When I ask for 31 blocks, I get ERR_FRAMING (0x09) error. I don't understand this error... Could you kindly explain it to me, please? I have, also, searched in ST forum for this error, but I haven't seen any solution related to my issue.- When I ask for more than 32 blocks, I get ERR_RF_COLLISION (0x1D) error. Again, I don't understand why I get collision error because I have only one tag in the field of the RFID. Could you explain me this, also, please?Another t

I'm working on an application that requires a very fast UART speed. The STM32H7 allows a UART speed of 17 Mbps, which is just barely enough, but should work. However, other than the fast UART speed, I don't need to do a lot of processing. I would have much preferred to use an ultra-low-power device instead.Because of this I want to run the MCU clock speed as low as possible. However, using CubeMX and the clock configuration tool, I'm running into issues where when I drop the CPU clock, the maximum speed of the UART peripheral clock drops too low for my needs. I've traced this down to what I believe is a voltage scaling "VOS" issue. Each VOS voltage scaling value places a limit on the maximum UART speed (see General operating conditions table, fpclk value).So my question is basically, Could I run the CPU at 140 MHz (which seems to recommend VOS3) but set VOS to VOS0, which would allow the 17 Mbps UART speed? Or do I need to us VOS3 with that low of a CPU clock? Are there any issues I sh

Hi, I am planning to build a motor controller using ST Motor control work bench is it possible to use STM32F072B-DISCO with custom power board with this GUI. If yes what are the limitations    Board link: https://www.st.com/en/evaluation-tools/32f072bdiscovery.html

I have a doubt regarding the motor state flow diagram. Currently, i am working on sensorless FOC of SM-PMSM using STM32G321B-ESC1 discovery kit with the help of MCSDK 6.1.1.To understand the motor state flow, i referred few documents from the documentation of MCSDK. But, there is only explaination of 6 step library (UM3042 STM32 motor control SDK - 6-step firmware library).Below is the Motor state figure from UM3042 for 6 stepCan someone please share me the motor state diagram for FOC sensoreless or related document for FOC library? Thanks in advance:)

Hi,I'm developing STM32G031 UARTs using registers and the CMSIS library. I’m using NUCLEO-G031K8 UART2 over an embedded STLINK/V3 on board and UART1 over an external CP210x UAR/USB adapter.  I have a problem receiving data to UART1. No problem to receive data to UART2. Also both UARTs transmissions are working properly. I’m using the same configuration: // USART1_TX = PA9 // USART1_RX = PA10 // USART2_TX = PA2 // USART2_RX = PA3 void my_uart1_conf ( void ) { RCC->IOPENR |= RCC_IOPENR_GPIOAEN ; // Activate clock in GPIOA GPIOA->MODER &= ~GPIO_MODER_MODE9_0 ; // Set Alternate Function (AF) for USART1_TX GPIOA->MODER &= ~GPIO_MODER_MODE10_0 ; // Set Alternate Function (AF) for USART1_RX GPIOA->AFR[1] |= GPIO_AFRH_AFSEL9_0 ; // AFRH is AFR[1]. Choose AF1 GPIOA->AFR[1] |= GPIO_AFRH_AFSEL10_0 ; // AFRH is AFR[1]. Choose AF1 GPIOA->OTYPER |= GPIO_OTYPER_OT10 ; // Choose Open_drain for RX to avoid P-MOS transistors issues //GPIOA->PUPDR

I soldered a stm32g030F6P6 on ssop-to-beadboard PCB. When I connect Vdd(pin4) to 3V, Vss(pin5) to ground it will over current and burn it self (about 200mA input current). I have burnt 3 of it.I find out that the input resistance of power rail is super low at around 10 ohm and I am 100% sure I did not bridge the pins together, here is the picture where pin number is aligned with breadboard and white line is ground blue line is 3V capacitor is 0.1uFWhat seem to be the problem here?I have burnt 3 of it on 3 different ssop-to-beadboard PCB therefore can rule out the possibility of bad soldering.

I'm currently trying to build a custom PCB using LSM6DSO. I just have few questions about the pins I don't use. I have no need for SPI communication, interrupts and VDD, not VDDIO cuz I need to power it through my RPi. I only need I2C communication and I need the PCB to be as small as it can get (like 1.6 cm in width, 2.4 cm in length), so I thought of connecting the unused pins, which are VDD, INT2, SCX, SDX, SDO/SA0 in this case to the ground with capacitors and only have the pins for I2C for soldering. The X's on the pins mean I should leave them unconnected.My question is, are there any pins on the schematics I made that should not be connected to the ground and should rather leave them unconnected after making their pins? I am very much new to circuit. Any advice, recommendation or anything helpful is very welcome.

When developing my external loader I changed its name.It works well under this new name.But STM32CubeProgrammer V1.14 continues to want to load the file that no longer exists:  20:20:04 : STM32CubeProgrammer API v2.14.0 | Windows-64Bits 20:20:04 : Error: Flash loader C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin/ExternalLoader/AASun_W25Q64_V1.1.stldr cannot be loaded. 20:20:04 : Error: Flash loader C:\Program Files\STMicroelectronics\STM32Cube\STM32CubeProgrammer\bin/ExternalLoader/AASun_W25Q64_V1.1.stldr cannot be loaded.  How can I avoid this message? 

Hi supporter, I'm working with ST25R for NFC reader which read e-passport.In our current set up, system run on STM32MP1, some open source provides example via CCID and pcsc-lite driver.Based on my knowledge, currently only userspace application is supported.Any chance that we can make pcsc-lite works with ST25R? Thanks,

Hi,I just wanted to mention that its really frustrating that in the STM32H7 HAL Manual, in the RCC Section,1. There isnt a simple step by step guide to setting up the clock config to follow along, like there is for other things like GPIO's. As someone who's just starting in embedded with STM32, I really would want STM to include step by step guides for every section in their HAL Manual.2. In the RCC Section of the HAL Manual there is no section which talks about Voltage scaling. I luckily stumbled across it but what if someone else did not know about it. There should be the step by step guide, which includes the steps for setting the voltage regulator as per the desired clock config. I know that this may be something that is 'supposed' to be done in STM32CUBEMX, but in order to really learn, I don't want the software to do everything, I want to learn and see what actually goes on. The HAL Manual has been pretty good with that but there's tons of sections like RCC, and even PWR tha

Hi,I have small headless firmware and wish to include a version constant in the Binary image so I can determine the version when using the debugger.It's easy if your project has a display, but I can't figure out an easy way of doing it for a simple system.  If I put a string constant in main.c the linker doesn't include it as the string isn't used anywhere. Does anyone know of an easy way to do this with an example?RegardsRob  

I used stm32wb55rgv6 and stm32wb5mmg in the stm32wb series for simple Bluetooth projects (using hw_timeserver to send notification data), and then used nRF Connect to receive notification data. My program and design are basically the same, but only stm32wb55rgv6 succeeded, while stm32wb5mmg failed, as shown in the figure:  I have compared these two projects many times, and based on an5289, I think his process is quite normal. I guess there is something wrong with the design of HW_timeserver timing triggering. For the specific design, see the program in p2p_server_app.c below: /* USER CODE BEGIN Header *//********************************************************************************* @file App/p2p_server_app.c* @author MCD Application Team* @brief Peer to peer Server Application******************************************************************************* @attention** Copyright (c) 2023 STMicroelectronics.* All rights reserved.** This software is licensed under terms t

Hello Community,I am working on a Vibration Measurement system that will be subjected to lifetime vibrations ranging from 10Hz to 2000Hz at approximately 1g with expected lifetime of 2 years with 16 hours daily vibration & 8 hours of no vibration.I'm considering using the STM32 LQFP64 package (of STM32G0B0 & STM32G474) for this application but am concerned about its mechanical robustness under such conditions. The temperature shall always be less than 75'CCould anyone provide information on the vibration tolerance levels of STM32 MCUs in general, and the LQFP64 package in particular? I've found limited to none data/information/specifications on this subject and would greatly appreciate any insights or firsthand experiences.Moreover, I've noticed multiple products that feature both an MCU and MEMS Accelerometers on the same PCB, which are installed in environments subjected to lifetime vibrations of upto 3g over 10Hz to 2000Hz range. Can someone share thoughts on the long-term r

I am reading quaternions from the SFLP and converting to yaw, pitch and roll (YPR). The results are remarkably stable and accurate! I noticed though when performing some simple testing with the sensor on a breadboard and the breadboard flat on a tabletop that the YPR values return NaN when the yaw is ~180 degrees. I need to investigate further the individual byte values from the FIFO under this condition but I am pretty sure this is due to the halffloat-to-float conversion. Are you aware of any such problem or have you seen this before, and is there a recommanded work around?

Hello, have been working with my L476RG and was curious if any of the ST accelerometers would be compatible with this board? I didn't see any in the X series of nucleo expansion boards.ThanksDG
