Solved

We have a current device that utilizes the st25r3911b and the stollmann stack.Now that the Stollmann NFC protocol stack is no longer, is there a stack that can replace it in Android in the the ST world and the ST25R3916 or is NXP the only NFC solution for Android? I'm a hardware engineer on theproject.Thanks for reading,Don

What should I take care of when using a single ended 50 Ohm antenna without AAT?What changes I need to do with the analog configures comparing to the example one given in X-CUBE-NFC6? Are there some references for this usage case?Thanks.

Hello,I want to use SDL2 to run some application on stm32mp157 DK2.I build st-example-image-x11 and when LDME service started I can run startX and run my application. I want turn off LDME manager and only run startX but when I do this I get error:last dlopen error /usr/lib/dri/stm_dri.so: cannot open shared object file: No such file or directoryfailed to open any driver (search paths /usr/lib/drilast dlopen error /usr/lib/dri/kms_swrast_dri.so: cannot open shared object file: No such file or directoryfailed to load driver: kms_swrastIn /usr/lib/dri I have only swrast_dri.soMy xorg.conf is empty.Do I need add some driver configurations in xinitrc /etc/X11/xinit ??Regards,Adrian

I like the way CubeIDE generate the code. Especially with "Generate peripheral initialization as a pair of '.c/.h' files per peripheral". This is very helpful tools not only for start the project but also for checking particular functionality.Why examples delivered by STM are not in exactly this shape?It will be very comfortable to compare our code with STM's examples code.It will be also welcome to see the examples code with "Generate peripheral initialization as a pair of '.c/.h' files per peripheral" option. The code is more clean. Please consider use this option at least for Low Layer examples.

MCU: STM32F030CCT6Programmer: ST-Link/V2Software: STM32 ST-LINK Utility v4.1.0.0I'm new to STM32 mcu's and trying to comprehend the memory map.The Reference manual (RM0091, DocID018940 Rev 9) states in section 2.5 that when the Boot0 (pin) is high and the nBoot1 (bit) is high, the System memory is aliased to the boot area 0x0000 0000.And when the Boot0 (pin) is low, the Main Flash Memory is aliased to the boot area.To get more comfortable with working with ST-LINK Utility and test my understanding of the memory map I tought it would be a good excersise to verify this.So using the STM32 ST-Link Utility I compare 3KB of Main Flash memory with the boot area while Boot0 (pin) is low.And yes, the memory content between boundaries0x0000 0000 - 0x0000 0C00is idential to0x0800 0000 - 0x0800 0C00This is as expected.Now I reboot the system while holding the Boot0 pin high (and nBoot1  bit is also high), thus I expect the System Memory content at the boot area.But the memory content bet

Hi,I'm looking for C Software library for IMU platform model ISM330DLC.My setup:IDE: SPC5StudioMCU: SPC570SxxPlease, where can I find this library?ThanksLeo

Hallo everybody,I'm still very inexperienced with the board and the tools.I start Unico and contact the STEVAL-MKI109V3 and get the following error:Please can someone give me a hint on how I can update the STEVAL-MKI109V3 board and where I can get the latest firmware from?I have already installed the STM32CubeProgrammer.When trying to switch the STEVAL-MKI109V3 board into DFU mode, the board appears in the Windows 10 Device Manager as "STM32 BOOTLOADER".Many thanksCarsten

I am looking to get a good power consumption measurement of my STM32L011K4. I bought the Nucleo-LPM01A for that. However, the project I've loaded onto my L011K4 does not load when in USB mode. I've checked the user manual UM2243, but that described only how to measure the power of the MCU as use case.What should/can I do?

Hi. i have some problem when verifying the board composed of STM32F030RCT7 with Keil IDE (MDK ARM). I still don't know much about FW, so I ask a few stupid questions.​Problem 1. I am basically setting the project through STM32CubeMX. I checked that the option of [Set All free pins as analog] in the Code Generator of the Project Manager reduces the power consumption. I checked the [Debug Serial Wire] option. With these two settings, I found that the power saving option is checked and debugged as desired, but I don't understand one thing. In the Keil project setting, the reset after flash option is used among the Debugger options, and the timer that should be output every 1 second after uploading the firmware is output at a speed faster than 1 second. If you press the button connected to the RST, the output is normally every 1 second from then on. I am wondering why this is happening.​Problem 2. Currently, 4 ADCs and 6 GPIO Outs are to be used. ADC tries to use 12 ~ 15 as DMA, GPIO uses

Hello, I have recently switched computers and i have installed Keil IDE and CubeMX 5.6.0 onto the new PC, but when i create a project i get an error saying:"The code is successfully generated under........ but MDK-ARM V5.27 project generation have a problem" I have tried multiple different locations to see if it was that causing the problem , but no change. I installed CUBEMX 5.5 and 5.4 and they both show this problem however if i used V5.3 the project generates successfully. i can obviously just work from V5.3 but this would mean i cant open any recent projectsAny help would be appreciated -i'm out of ideas what to try

Is It possible to separate the STM32MP157A-EV1 MPU Subsystem Daughterboard (MB1263) from the motherboard (MB1262) to integrate it into a Motherboard of our design? Are there any limitations for its use when not paired with MB1262?Thank you!

STM32F103 MCU , CubeMX generated code for Atollic True studio.TIM1 configured in Combine Channel -> Encoder Mode , User Parameter ->EncoderMode -> Ti1 and Ti2 , NVIC Settings -> TIM1 Update Interrupt enabled.HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef *htim) - method implemented in main.ccontains only a GPIO LED togglemain() method contain timer init generated code and timer start callHAL_TIM_Encoder_Start_IT(&htim1,TIM_CHANNEL_ALL);Also contains methods to print encoder counts.As the encoder is turned, encoder counts are printed, but when the Counter period ARR - value over flows the interrupt is not fired.Is period elapsed the correct call back? do i need to do something more?I tried with TIM4 similar setting enabled global interrupt, but same results, encoder count is printed but overflow / underflow interrupt is no called.Any suggestions?RegardsSamit

Hello,I have a NUCLEO-H745ZI-Q board that I am trying to configure as a FS USB device setup as a Virtual Port Com. The only changes I have made to the stock CubeMx setup is removing ETH and setting up two encoder inputs on TIM2 and 5. I've tried disabling vbus sensing. I've also tried with and without the USB PWR EN jumper (which there is basically no documentation on). I'm assuming that I should not have the jumper enabled since I have the USB configured as device only. I've tried to read through as many docs and forums as I could seeing if someone else has a similar issue, but not finding anything else. I've seen other posts like this one that suggest adding HAL_PWREx_EnableUSBVoltageDetector(), but I already have that (seems it's been fixed in CubeMx). There was this post about the BCD being enabled, but seems like some info is missing. I am powering the board over the stlink USB connection. For the moment, I have jumpers JP6, JP7, and JP8 removed (from what comes stock). JP6 and JP

Hi,We bought ST25RU3993-EVAL from your company. This evaulation board worked. I installed ST25RU3993 RS. I set Reader Settings,choosed Antenna. I did everything you told in video. You mentioned in your demo video that you can read up to 11 meters.But i can read up to 50 centimeters. You used A0025 in your video. Is this about or is there something i missed?

Dear all ,My project is to read ST25TA64K(NFC Forum Type 4 Tag,ISO/IEC 14443 Type A) Tag with NFC03A1 Reader and hosting MCU is STM32L452.I am able to detect the Tag by Idle command.An wakeup event is getting occured after sending a Idle command.I am able to get a UID by executing the anticollision procedure which is mentioned in the examples of CR95HF datasheet.But i am unable to get any Response to RATS command.Should i must send the RATS command to read the Tag.I am not getting response to Selection command of CC file.My task is to write some info into NDEF file and read it back.I am not using any firmware from st.com(https://www.st.com/en/embedded-software/x-cube-nfc3.html).I am wrting my own firmware to read the tag.Is i am going in a wrong way?Please give me the suggestions.Thanks in Advance.Regards,Praveen.

In X-CUBE-NFC6 demo, the NFCID of NFC-A CE mode is set to:static uint8_t ceNFCA_NFCID[] = {0x02, 0x11, 0x22, 0x33, 0x44, 0x55, 0x66};I wonder if this is randomly generated or there some rule to set it. For example, if I need set uid0 (first byte) to some manufacture ID ?Best regards.

Hi all,I have a few questions regard the topic above.Is it an NFCA ISO standard that the PICCs will use BPSK (instead of OOK) to transmit data to the PCD for rates higher than 106? Does the ST25R3916 chipset and/or DISCO board supports speeds up to 848 officially for NFCA?Is this a the correct way to make a bitrate change? I am setting up the speed change is through the 14443A tab. After a successful RATS, I issue a PPS to the PICC to request it switch the DRI/DSI (the GUI implementation has a bug, it swaps the values when calling into the firmware) and then go to the Debug tab/ModeandSpeed and select NFCA and change the TX/RX speed reader bitrates locally. I also looked into the ST25R3916 datasheet to see about demodulating BPSK incoming RX (>106). Can I assume when I set the RX speed higher than 106 the GUI will send appropriate commands to switch the demodulation type from OOK to BPSK?Are there any analog front end settings that we can tweak via the GUI to try to make comms

Hello, I am working with STM32H7. I need to configure the CAN FD to work as Classic CAN 2.0. I have found an example that configures the CAN FD as Classic CAN 2.0, but in the example the system clock is different from my system clock. I need to find the method to configure the STM32H7 CAN FD as CAN 2.0. Please help me cause I am not able to find this method anywhere. Thank you in advance. Best regards, Vouria

I made a PCB with ST25R3916. And now is coding for it. The only example I can find is X-CUBE-NFC6. Because my usage of ST25R3916 has some differences with the NFC061A. For example, I don't need AAT and only use a fixed external attena (is it possible, right?) So, my analog configuration shouldn't be the same with NFC061A, right? I think I should do some changes with 'analogConifgTbl_NFC061A.c'. So, are there any docs about the usage of the RFAL analog config macros?Update:In AN5309, it states:In the RFAL, these settings are referred to as analog configs/settings and the library applies them as needed. These settings are conveniently grouped in a table that can be easily customized and generated using available tools. Are there some tools to help?Best regards.

I loaded the ​MB11414-A_v1.xml into ST25R3916 Discovery GUI. And find there is a register '0x68', but in ST25R3916's datasheet, I can't find 0x68, only 0x28. Where 0x68 comes from.If it's a typo, that is 0x68 is actually 0x28, write 0x00 to mask 0x20 should disable the external load modulation, right? But the comment is 'Disable Internal Modulation', why ?Similar to above, write 0x10 to mask 0x10 should enable the internal load modulation, right? But the comment is 'use external load modulation'.In analogConfigTbl_NFC061A1.c, same problem exist thereBest regards.

i am planning to use HSE on STM32G071GB (UFQFPN28 - 28 pin package)datasheet STM32G071 on page 41 does really make it clear if HSE pins are available in small package (28pin)datasheet states:PC14: OSC32_IN, OSC_INPC15: OSC32_OUTis OSC_OUT missing in datasheet. is there a typo?

During testing I frequently make changes to the source and re-compile it using "STM32CubeIde". Now, when trying to add/remove a variable from the watchlist ("variables" node in STM32CubeMon), I get the following message and my previous selection is gone."The variable list has been updated because the executable file *** has changed."So even the list of available variables has not changed (and I think even their address is still the same), I have to redo the selection.So is there a way to tell STM32CubeMon to update the symbol table and thereby keep the old selection?Kind regards,Thomas
