Hello,When is it planned to integrate freertos v10 with STM32H7 CubeMX ?Thank you,ran

Hello all,I just got my new toy before few days named as ST25DV04K Dynamic NFC/RFID Tag.I have downloaded the firmwares, applications and rest of the things from the https://www.st.com/en/evaluation-tools/st25dv-discovery.html#design-scroll.I have observed few things while I'm observing its code which is downloaded from same link and i've found that they have included the USB drivers but won't call even not trying to manage the input from the USB(If I'm not wrong).Now I want to use it through the PC software, for that i need guidance to to get suggestion like which software I have to prefer, how to manage the GUI communication for that what are the implementation I have to do in program, such things. Can anyone please help me for this and guide me.Little help would be appreciated.Thanks in advance.

Hi ST,I'm wondering about the sample rate of the LIS2DH* family and if the configured sample rate affects how the samples are captured. Specifically, when sample rate is changed, does that change how the samples are performed internally, or does is it the same process just happening less frequently? For example, if I switch from 10hz sampling to 1hz, does the chip integrate over a longer period while collecting each sample?thanks,paul

Hello everyone. I facing next problem:Just yesterday, TrueStudio worked perfectly, but program lost its lost capability to compile anything (not older project, that I compiled nicely till yesterdey, not new, CubeMX-generated projects).I'm getting build output just like on attached screenshot with every project.Also, I've got one of compile outputs, that consisted of messages like this: junk at end of line, first unrecognized character is '*'Only thing I could tie to what's happend, is that I've installed ASAP Excel utility, BUT I've DELETED it already, REINSTALLED TrueStudio, and getting same result.Also, CubeMX has updated it's libs today, but since older projects don't work as well, I don't suppose that it's him...No one beside's me didn't touched computer, so I'm pretty sure, that no preferences was changed manually.Any help/hints, what could it be? Thank you.Truestudio 32bitVersion: 9.1.0 Build id: 20181011-1241

Hello,In STM32H7 cube examples I see the following related fatFS examples:en.stm32cubeh7\STM32Cube_FW_H7_V1.3.0\Projects\STM32H743I_EVAL\Applications\FatFsFatFs_MultiDrivesFatFs_RAMDiskFatFs_SDRAMDiskFatFs_USBDisk_RTOSFatFs_USBDisk_StandaloneFatFs_uSD_DMA_RTOSFatFs_uSD_DMA_StandaloneFatFs_uSD_StandaloneWhich of the above can be used with the internal flash memory ?Thank you,ranran

We are using M24LR64E for configuration and event logging, try to use password to protect configuration data area. In the user manual(DM00047008.pdf), in Figure 12 and Figure 13, the password address is 0900h, but in Table13, I2C byte address is 2048, 2052 for different sectors.Another question is I2C_Write_Lockbit_area command doesn't have I2C data format (such as Figure 12, 13).ST25DV DVK has source code "st25dv.c" the firmware with all the functions for command codes, but I can't find the source code for M24LR64E.

Hello,I'm using a Murata CMWX1ZZABZ embedding a STM32L082 and the HAL v1.8.1.HAL_SPI_TransmitReceive() returns wrong LSB data :-expected : 0x33, received : 0x33 : OK-expected : 0xAA33, received : 0xAB32 : error-expected : 0x00, 0x01, 0x02, 0x03..., 0xFE, 0xFF, received : 0x01 0x00, 0x03, 0x02, ..., 0xFF, 0xFE : errorThe logic analyser shows the expected values from a 23LC1024 SPI memory slave :The two last bytes are AA33 as expected.Here is the initialization function and the receive function wrapper :SPI_HandleTypeDef _hspi;   void configureSPI(void) { /* Peripheral clock enable */ __HAL_RCC_SPI2_CLK_ENABLE();   _hspi.Instance = SPI2; _hspi.Init.Mode = SPI_MODE_MASTER; _hspi.Init.Direction = SPI_DIRECTION_2LINES; _hspi.Init.DataSize = SPI_DATASIZE_8BIT; _hspi.Init.CLKPolarity = SPI_POLARITY_LOW; _hspi.Init.CLKPhase = SPI_PHASE_1EDGE; _hspi.Init.NSS = SPI_NSS_SOFT; _hspi.Init.BaudRatePrescaler = SPI_BAUDRATEPRESCALER_256; _hspi.Init.FirstBit = SPI_FIRSTBIT_MSB;

    my reader is st25r3911b-discover,the tag is st25dv04k,when I write file(the bin file )to tag,the reader wrote a block (four byte)to tag every time ,how to designer reader for writing more block to tag every time.for example two block or more.thanks.

Hello,I flash my STM32 boards with the STM32 ST-Link Tool. But everytime I update my hex file I have to select the new one manually. Is there a way to let to do it itself?

Hello!I am new to this forum and I have a reasonable doubt regarding ST25R:We need to evaluate ST25R3911 for a new development where the main goal is that mobile phones (both Android and iOS) could read it as an ISO14443-A card. We would like to configure an NDEF as a NFCForum type 2 for example and the mobile phones read this as a card. This is because as far I know, iOS doesn´t let P2P and only can read cards... We do not find any info about emulation in Rfal driver so we are afraid that it is not possible with this chip. Do you have any idea? If it would be possible, Can we use ST25R3911B-DISCO software to configure it and test it?Best regards,J-RAM

Hey guys,I have a very big problem. For a reason I don't understand, my CubeMX project which worked really fine and had no problem at all did now get the following error as I was regenerating code (I did this a hundreds of times without problem but since last thursday I get this error) : "The code has successfully been generated under ... but STUDIOproject generation have a problem".Since then my project is not working correctly anymore. For example my UART is not transmitting any data correctly but receiving. I tried to just save the project new and generate new code but the problem is the same and no TrueStudio project is generated.I noticed that STM made an update for CubeMX (5.00) and so I installed it and updated all the firmware packages and migrated my project in hope that this might correct the error but nothing changed.Now I don't know what to do. How do I get my project to work normal again? I also tried to make a new empty project with True Studio and just copy the generated

I have an STM32F429 Discovery Kit (with included LCD screen). I am running Atollic TrueStudio. I want to run one of the examples provided in the FW package at:...\STM32Cube\Repository\STM32Cube_FW_F4_V1.21.0\Projects\STM32F429I-Discovery\Examples\LTDC\LTDC_Display_2Layers\First, I tried following the instructions on the Atollic TrueStudio blog found here:http://blog.atollic.com/how-to-import-thousands-of-stm32cube-example-projects-into-truestudioThe import reported as being completed without errors, but the result was just a mess of folders and files that couldn't possibly compile. Next, I made a new project using STM32CubeMX with the required peripherals in their default Mode, and then copied the contents of the inc and src subfolders from the FW example into the generated CubeMX project. The trouble is that there are still more #includes I am missing. For example, main.h has in it:#include "stm32f429i_discovery.h" #include "../Components/ili9341/ili9341.h" I did a search of the entir

Posted on January 20, 2017 at 19:36Hello, I am new to the CubeMX community and the problem I am having is that when I open CubeMX and try to start a new project all I get is a blank screen where my device selection should be. I uninstalled the application and reinstalled it and restarted my laptop (HP using Windows 10) and still have no luck. However I am still able to open previous projects created. Has anyone else had this issue and if so how do I fix it?Thank you

Dear all,I'm checking if a variable assignement is atomic or not. I know that are many stuff on this subject but I need to approach from a low level perspective to better know what happen under the scene and then have better control of my code.To do that I'm looking the dissassembler window during the debugging stage, I'm using the IAR IDE v8.32.1 but my question is not related to this specific IDE/Compiler.A variable with name Nstep_total is update under ISR and is also declared to be volatile, here below my declaration:volatile int32_t Nstep_total = 0; // Updated under ISRUnder the ISR code I've to write the Nstep_total variable and into the main code I have only to perform a read. This operation is made by means of a temporary variable called Nstep_total_tmp definited into my main code as.int32_t Nstep_total_tmp = 0; // Temporary variable used to store the Nstep_totalin other words, instead to use directly the Nstep_total variable in my calculations, I simply do an assignement

Hi,I'm working with a ST25R3911B RFID chip associated to a STM32L072 uC.I use the "STM32CubeExpansion_NFC5_V1.2.0" project, ported from STM32F401 to STM32L072.This project enables to set the ST25R3911B  in wake-up low power mode.Now I'm trying to set the STM32L072 in standby mode with the ST25R3911B  using the IRQ.I can wake-up the STM32 with IRQ generated by ST25R3911B  when a badge is passed but I cannot read the badge.So my question is : is the "STM32CubeExpansion_NFC5_V1.2.0" project compliant with uC low power mode like standby ?Regards,Matthieu

Hello everyone,i have gone through ST25RU3992 it has written that it will support ISO18000-6C fully and ISO18000-6A/B in Direct Mode. will it support ISO18000 6D some how or else any other option that we can configure it in ISO18000 6D protocol ? "thanks"

hello!  I was devolving my project on the "STM3220xG eval-board" (based on controller "STM32F207IGH6"). Now as my custom made controller board is ready (based on "STM32F205ZGT6"), I ported my code for it by changing in peripheral's Pin-numbers and Keil settings (controller selection).   In my custom made controller board I've kept the crystal settings same as eval board, but still due to an unknown issue my clock source keeps on switching on HSI (16Mhz). I've tried with 16Mhz crystal as well with PLL-M=16, PLL-N=240, PLL-P=2, PLL-Q=4 and HSE_VALUE =16000000 but still, no positive results.  on the other hand, I've ported the same code for NUCLEO-F207ZG with PLL-M=8, PLL-N=240, PLL-P=2, PLL-Q=4 and HSE_VALUE =8000000 and its working quite well.    can anyone help me with the understanding of "Clock's Initialization" or rectifying my issue?Thanking with RegardsAatif Shaikh

Hi,I tested FMC_SDRAM_DataMemory Example of STM32F769I_EVAL.I found out that the data written to SDRAM is not correct.See below picture for your checking. I believe HAL and FMC driver in system_stm32f7xx.c is not correct. Please advise me how to make it correct. Thanks.Regards,Thiha Kyaw

What are the difference among operating modes in magnetometer of LIS3mdl in terms of the number of samples used to generate each output sample?For example, I found that in ISM303DAC the number of samples used to generateoutput sample is four times less in Low-Power mode than the number used inHigh-Resolution mode. As you know the operation modes in ISM303DAC and IIS2MDC are just two modes including low power and high resolution, but in LIS3MDL there are 4 different modes of LP, MP, HP and UHP. So,,1- please let me know these difference in terms of number of samples per data output. 2- In addition I want to know if there is any difference in resolution of operating modes? For example if I select the Low power mode in LIS3mdl with +-2Gauss range, how would be the resolution in other modes?

I have a microcircuit M24SR04-Y, on which I recorded information using the NFC.I need to read this information using i2c.I read the datasheet and understood the circuit of communication with the microcircuit.But I am a novice and without an example it is very difficult to understand.Tell me how and in what form to send commands. If you show an example of communication with the chip, it will be great.Thanks!
