Solved

Hey there, We have a product that features one PCB that embeds the ST25R3911B with a custom NFC antenna, acting as a reader (initiator mode).For the CE certification process we are currently pursuing for our product, the certifying body required to perform RF testing for NFC as well. They suggested to have a look at the product page looking for a testing firmware similar to what we could find for BLE RF testing with the BLUENRG-LP. Unfortunately, we could not find any such thing. It would very nice if someone could with any of the following questions:Is there any testing firmware/software or some guidelines to perform RF testing for NFC communication with the ST25R3911B?Has someone already performed RF testing for CE certification of an NFC initiator, i.e. the ST25R3911B?Are there some guidelines for writing such a RF testing firmware? We already opened a support ticket, and they suggested us to post in the Community forum, so here we are... Any feedback would be of grea

I am using lsm6dso32x.An5629 Datasheet Section 8 FSM Configuration Example implemented only Accelerometer.I don't understand.It seems that you did not set what data(gyro or accel) you use with FSM, but I don't understand how it was used as an Accelerometer.How do I use it as a gyroscope?Also, Can you tell me specifically how to create the Threshold? I don't quite understand.Thank you

I communicate with a VL53L1X-SATEL over I2C from a PSoC 5LP as I2C-master. The sensor as I2C-slave acknowledes commands as expected, but each register I try to read returns 0x00. I tried a for loop to read every register from 0 counting up, but the sensor always return 0x00. What could be a reason for such a behaviour? Please see the scope view of a read sequence to register 0x83.      

Dear ST Community membersI am currently designing a PCB and utilizing the STM32G473VET6 MCU. I have noticed that there are several unused pins. Should I leave these pins unconnected or is there a recommended course of action for dealing with them?thanks and regardsNeeraj

Hi all,I setup DMA normal mode, on RS485 port where I receive more or less 1 byte per second.Also, I have DMA normal mode on a debug serial port.I want to send back on rs485 the characters I receive on that port.What I observe is that if I add the following printf(), that redirects output to debug UART, in HAL_UARTEx_RxEventCallback()printf( "errCode=%i\r\n", retCode );everyting works fine, with TeraTerm software, I can see the characters I input in RS485 window displayed correctly.BUT, if I remove the printf(), when I press keys in rs485 window the cursor only moves one space to the right not showing any character.Also, if I set a breakpoint at the begiining of HAL_UARTEx_RxEventCallback(), it only gets called once on the first character I type in rs485 putty window and the sending back of the character received is ok, but then on subsequent pressing of keys HAL_UARTEx_RxEventCallback() is never called and nothing is shown in TeraTerm window.I'm using STM32G070RBTx, STM32CubeIDE v. 1.

Hi, Please provide park date code clarification of "D231". Part Code:LPS22HHTR Thanks, Arun

I am currently developing the firmware for a project.  I have two boards, running identical firmware but the operating temperature between the MCUs on the boards has about a 10°C difference, 43°C vs 53°C (confirmed with a thermal camera).We have more boards, but before I go too far with this, I was hoping to get some input from someone on what to expect.  I checked the power supply voltage on both boards and it is identical at 3.40V.The STM32G474 is running at 144MHz with 230.4kBd continuous serial communications.  There are two DSMPS power supplies each using one HRTIM PWM signal from the MCU, switching at 200kHz.There are 9 ADC channels being monitored continuously.  The average main loop execution time it 39us with a worst case of 83us.Any thoughts? 

May i know what is the part number for this parts.

Can any one suggest ,1. Which static code analysis tool can be used  by STM32CUBE ide?2. The code analysis that is already available in the CubeIDE can be used to generate the Static analysis report?   Thanks in Advance.

Hi,I'm using STM32CubeIDE 1.4.0 to build an application (BLE Hid) for the P-Nucleo-WB55 board. It's looking for an include file stm32wb55xx.h which is missing. Any idea where to find this file?Thanks,Jim

I have an app running on an STM32F373 and need to save 'presets' as persistent non-volatile data.  Each preset is 500bytes and I would like to save at least 100 presets.What is the simplest method?  Should I use a removable SD card type solution, or is there non-volatile memory I can use which will take enough 'read-write' cycles to be used to save presets?  I guess having a removable SD card solution would have some benefits, like using json file format so presets can be created outside the uC.Thank you,

I'm successfully using vn5e160str's to drive some high current outputs, but it would be useful if I could multi-purpose these outputs to support high frequency PWM. The vn5e160str seems to max out at about 50kHz, and I need a stable 800kHz.The PWMd load is of course only CMOS level voltages/currents but I'm trying to avoid having separate output connectors for high current and pwm modes so a single device/circuitry would be idea.Can anyone recommend a suitable similar component that can facilitate this? Cheers

Hello , I have initialized two timers , Timer3 and Timer9. Im using Timer9 with 137uS period , setting my gpio pin high , starting Tim3 Interrupt with 54uS period for now .When Tim3 Interrupt occurs I simply reset my gpio pin.My problem is that I should have a high pwm for 54uS and 137uS pwm in reset state.I have thoroughly checked individual timers to just toggle single gpio in 1 single interrupt , both give me a stable 137uS pwm and 54uS pwm . But as i use two different gpio's to set and reset my gpio. I get irregular pwm that has values randomly changing. My pwm will have a constant 137uS low and a variable high pwm state which is Max 122uS for now as I said its just fixed 54uS so I also did not enable autoload preload .This is the first time I'm doing it this way.My Code :Timer Setting : void MX_TIM3_Init(void) { /* USER CODE BEGIN TIM3_Init 0 */ /* USER CODE END TIM3_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig =

We are trying to use software "STM32 st-link utility" to program stm32h563 series MCU.However, it could not recognize our target MCU and shows "no target connected".Stm32h563 Target not connectedThe SWD pin connections are correct, we are able to do programming with software "STM32CubeProgrammer" :(Same device and same environment)Stm32h5_upgrade_programmerDoes software "STM32 st-link utility" support programming Stm32H5 Series MCU?If not, would there be any update for software "stm32 st-link utility" to support stm32h5 series MCU?

I used the lsm6dso32x_read_data_polling example and got the same result as above.(with SPI)Is this the correct value?And when I checked the values ​​using Unico GUI tool, I got the same values ​​as above.Although the values ​​are similar to the example, they are slightly different. So I'm a little confused. Is this okay?Thank you.

Hello,I'm using the Nucleo-WL55CJ kit to test the Lora connectivity with TTN server.At first, all worked fine and I received my data, but now the kit is unable to join the networt with the following error "DevNonce is too small".Any idea?Thanks.

Hello there!I've been trying to make the Lora-FOTA example portable by converting the include paths, resource links, linker path and pre/postbuild files to be "project related paths" instead of absolute paths.Everything worked out very well with kms_blob and secore projects. I've been getting an issue with bfu project build.I'm getting this error when I'm trying to compile the project after I've updated all the above mentioned paths.1. I have moved the SECoreBin project 1 dir back.2. I have renamed the build output from "Debug" to "BUILD_debug"3. I have compiled first the kms_blob then the secorebin and lastly the bfu project (which ends up in error)4. Other two builds are successfull with no errors. Is there anything missing ?1. I'm suspecting workspace related issues (even I don't see any workspace relation in all the paths or in the .cproject or in .project files2. Is there fixed locations regarding the assember for this project ?! Am I going nuts ?! Kind regards,Kyf

Posted on March 31, 2014 at 16:27I have a M24LR-DISCOVERY package, and I'm looking to use the CR95HF ''wand'' to program and communicate with an M24LR04E-R, preparatory to final manufacture of a high-volume (500k-to-millions units) product. We need to do block reads and writes using ISO15963/M24LR protocols. I have the stsw-95hf002 (AN3954 v3) source code package for C++ development. Unfortunately, it does not include APIs for ISO15963 or M24LR-specific protocols; neither do the supplied Windows DLL and lib files. I also downloaded the stsw-m24lr006 package, a firmware set for the board that does include ISO15963 and M24LR-specific support - however, these libraries do not, at first glance, appear easily or helpfully adaptable to Windows-USB software. Before I burn time reinventing the wheel (and delaying the project), does ST (or anyone else here) have CR95HF Windows libraries for these protocols? Many thanks in advance, Jon (Incidentally, the stsw-95hf002 source code package has ser

Hello,Is it possible to get the raw image from STHS34PF80 sensor? And what is the resolution of this image in pixel. I would like to know if it's possible to to use this sensor to count how many people are in the field of the sensor.Thanks,

I created a button widget with stem win library. The button click is detected but button release is not happening. I tried using some demo programs there it is working. I have attached a basic program which shows when a button is pressed and released. I am testing this on STM32F429 discovery board. 

Hi,I'm working on Power Line Communication with ST8500, with evaluation board equipped with STM32G0 and ST8500.I'm able to send and receive UDP messages between 2 nodes, but I'd like to implement the IPV6 multicast feature. In particular, I want that one specific node send UDP datagram to all the nodes of the network.Multicast came into my mind, but I don't think it is implemented.Is there a way to do so?Regards,
