After writing a NDEF message to the M24SR02-Y NFC Tag the Chip doesn't work anymore. If I scan it with a NFC app I can see that under technologies NDEF isn't listed anymore. Before the writing process it was listed. Does anybody know a reason for this?

Hello,I'm trying to understand the LIS2DE12 behaviour. First, there is no AN (Application Note), thus I used the one for LIS3DH which seems close enough.What I want is that my accelerometer wake up my stm32. This works. After that I just want to read 1 sample to know the current acc value. But the FIFO system seems a problem for me. In the doc, it says the sample I get is the oldest one in the FIFO and that if I don't read fast enough data will be overwrited.I just want to read one sample for Z-Axis when I need in my code. Do you have any idea or clue?Thanks.Best regards, Simon

Hi,I try to make stm32l496 as a video camera device. I use Ov5640 sensor. The aim is that taking photos and send them to the host device directly (like a webcam). The challenge is that when I try to use high resolutions, due to I don't use any memory, how I can handle it and send the data through otg? I want to use WVGA resolution (800x480) with JPEG format.

For a project, I could grab a few STM32L4R5ZI-P µC and am not sure what to connect to the 2 SMPS VDD12 pins when I do not want to provide external voltage but use the integrated LDO.The datasheet is not quite clear on this scenario.I have no augmented power saving needs, so the internal LDO will be fine for me.So, can I just leave pins 70 & 142 floating, or do I have to apply some decoupling capacitors?Cheers,B.

I tried following this tutorial (https://community.st.com/s/question/0D50X0000BYnQt6/sensortilebox-not-connecting), but it looks like DfuSe is obsolete, and I should use the new STM32CubeProg tool. I couldn't seem to find any information on how to use the STM32CubeProg tool to restore to defaults. How do I use STM32CubeProg to restore to defaults?

I am using STM32H7 General Purpose Timers TIM2, TIM3, TIM4, TIM5 and their respective external trigger ETR using combined RESET and TRIGGER modes and I am configuring and starting Channel4 for each to generate One-Pulse output . All the configuration and startup steps followed, Base counter started, Channels started but It does not work.All the One-Pulse examples I found in STM app notes and on-line examples show only one case of the Timer slave mode for One-Pulse generation: using the TI1FP1 or TI2FP2 inputs from the channel pins. Not ETR, not ITx examples , but only those two.I suspect that only these inputs triggers are allowed for the Timer One-Pulse mode but the user manual on One-Pulse Ch. 39.3.13 fails to mention that.User guide for STM32H7 One-pulse mode Ch. 39.3.13 states:Starting the counter can be controlled through the slave mode controller. No limitations have been mentioned regarding the trigger choice for the Timer slave mode , although Chapters on Ge

I am developping a driver for a QSPI memory mapped memory on STM32H753.In SPI mode it works fine.When I switch to "quad io" mode (ie. 4 data signals) I read corrupted data. Adding some delays between reads improve the results (but doesn't completely solve the issue)Right now the CPU frequency is 400Mhz, HCLK is 200MHz and the QSPI kernel clock (SCK signal) is 12.5MHz.Is it possible that the QSPI freq is too slow compared the CPU freq ? I assume a slow SPI freq is just stalling the CPU for a longer time ?

I'm working with SPC56EC64L8, i want to enable FPU. But I don't know how to enable it.

Hi,I try to bring up the NFC06A1 on an Arduino Uno with the Arduino IDE.If I compile the ST example (X_NUCLEO_NFC06A1_HelloWorld), I get an fatal error:C:#######\Documents\Arduino\libraries\STM32duino_ST25R3916\src/rfal_rfst25r3916.h:51:10: fatal error: functional: No such file or directory #include <functional> ^~~~~~~~~~~~ compilation terminated. exit status 1Is there any solution to get the example running?Best regards,Sebastian

Hi...By using Text Area widget a string is displayed on a 480x272 resolution board. But I want something like, if we give '1' from keyboard through usart that data will be transmitted & it should display a string configured in TOUCHGFX IDE .I tried it by enabling usart pins configure in polling mode & in switch case when character is received it should display a configured string . switch(Usart_Buffer)  {  case '1' :    unicode::strncpy(textArea1Buffer,"Power on",7);    textArea1.invalidate();  break;  }I am not getting what is the proper way to do this ?

VREFBUFF is not available in STM32L431RCTx series, in datasheet it tells that "internal voltage reference buffer is not available", is there any other option to give External ADC reference for this series of STM32.

I used Cubemx to configured the system clock to 180MHz. Why is the system clock in the generated project code...... 6 zeros...... 16MHz:grinning_face_with_sweat:? Can I change 16MHz to 180MHz?It simply changes the number after "SystemCoreClock" to 180000000？

I am trying to use one of the Firmware Package demo projects using Keil v5. With the STM32F072 Discovery Board connected, the Device Manager shows the STM32 STLink driver is working properly under Windows10. In particular, I've loaded the DAC_SignalGeneration Project. Originally, I got an error that the Project was read-only but I changed the file attribute. Keil then updated the project from v4 to v5. I then re-built the project with zero errors. When I try to Flash or Debug, I get an error in Keil: Cannot Load Flash Device Description, C:\Keil_v5\ARM\flash\STM32F0xx_128.flmNo idea what this means.When I first connected the USB cable, it said there was an update for the STLink firmware. I think it updated it just fine to the latest version.Any ideas what I'm doing wrong?

Hello,Our Devices(50 devices) uses STM32WLE5CC and STM32WL V1.0.1 SDK. I have generated code with Lorawan. All system works perfectly for around 49 days, after that all devices get reboots.We found that it happens when HAL_Gettick() overflows(we send HAL_Gettick() value to our server on each uplink).I didn't use HAL_Gettick() function in any other function expect dding this value in lorawan frame , but uses Timer API to create timer and wake device on time.Please guide us how can I solve this issue?Currently can't generate issue again as it needs 49 days to overflow HAL_Gettick(). Is there any method I can set HAL_Gettick() time manually so I can be sure about that.Thank You

Hello everyone,I am trying to communicate with ST25R3920 using S32K116 host MCU. I managed to read some data but they seem meaningless according the datasheet. For example: I was trying to read IC identity register(3Fh) to test that if I am able to communicate with the device. When I send 3Fh with 01 prefix for read operation, I read 15h(00010101b) on second byte of buffer. That made me thought maybe I am losing bits during communication because I should read 2Ah(00101010) but then I realized when I to read different registers I get the same 15h value on different byte( like 3rd or 6th byte of receive buffer) and this value is meaningless for that registers.I tried to configure default options and run the power-up sequence properly but I don't even know if they are executed in right way. I am tagging a snippet that I use to send data to ST25R3920.So, I was not able to detect the problem causing this issue. What are the options I could try and what could be the issue? I'd appreciate any

HelloI am using the combination of F401RE and IHM16M1 for a project in my lab to drive a 24V BLDC Motor (max RPM 5000). Issues:1) I am unable to select the above combination in the Motor Profiler.2) When I try to generate code using Motor Control Workbench (5.Y), I generate code using CubeMX (6.3) and flash it using CubeIDE (1.10.1) -->I run motor using Motor Pilot but it always says "Speed Feedback Error". I don't know why this happens.3) No resources about how to make this combination work.4) I tried using the 6StepLib. However, the motor just spins and then stops making a humming noise (increasing), then stops. Sometimes it doesn't stop but runs at 450-500 RPM.Can anyone please point me to a given example for this combination? Or am I missing something?I am new to the ecosystem so I would appreciate any help or guidance. Thank you.------------------------------------------------------------------------------------------------ ****UPDATE****GMA, Thank you for helping me resol

Hi, im currently working on a project for universtiy and im quite new to stm32. I hava a sensor on my board that coummuicates via UART, were it dumps its data once per second. My problem is that the first HAL_UART_RECEIVE works as intended, but afterwards it always instantly times out, seemingly even before the set timout is over.
