I have only application of NFC ​, but I don't see support in HAL, Kernel or TrustZone of android

Dear Sir/Madam, We are the hardware engineer from Siemens Suzhou, our project used BLE chip BLUENRG-M2SA. Now we are preparing to pass the SRRC certification with our product, so where can I found the CE/FCC/SRRC certification documents that BLUENRG-M2SA has achieved. If you need more information or any questions, please contact me, thanks! Have a nice day!

Hello!Hav anybody workable sample of ZOOM in and ZOOM out detection of touchscreen gesture?

Hi everyone, my project using STM32L433ccu6 MCU (PCBA from china). ADC value read out freeze 2048 (0x0800) , but in my prototype with component from Digikey or Arrow everything ok. And I try to replace MCU I bought from Digikey to PCBA board , It's work !!!!Who has the same problem?Thanks,Chatchai B.

According to this post:https://community.st.com/s/question/0D50X0000C0vEvBSQU/cubemx-cmsisdsp-include-problemsit should be possible to use the latest CMSIS (e.g. 5.7.0 from https://github.com/ARM-software/CMSIS_5/releases/tag/5.7.0) in CubeMX 6.1.1. After package installation I can see it on the list but it does not appear under "Additional Software" section. Actually, this section is missing entirely.What I am trying to accomplish is to get the latest version of L1 cache management functions in generated code for STM32H7A3 MPU. Versions from CMSIS 5.7.0 package seem to significantly improved compared to those from STM32Cube_FW_H7_V1.8.0 package. Of course, I can generate code and then start making changes but I would rather not in likely case I need to regenerate.

Hello folks,I recently bought a stm32f410rb nucleo board and configured it in Linux(Ubuntu 18.04) using eclipse ,CUBEMx, IDE and programmer.Once build is through, I tried downloading the program and the verification is failing here.Could anyone direct me how to resolve this issue?

I am looking to change the functionality of the LEDs in this firmware. is there source code available for download?

Hello, I am new to NFC and I want to confirm if a dynamic tag can read data from a tag and then send that data to a processor.That's what I understood initially but now I am thinking that a dynamic tag is used to only store data and the processor can change that data but I still need a reader (ST25R) to read from a tag/dynamic tagAny help to clear this up is appreciated thank you,Chris

Hello,Is there any ressource describing the consumption during 10Hz Low-power mode ?On my side I think I can see little peaks each 100ms then one litle larger peak each 2 seconds.Is that the normal behavior ?Is it possible to find a typical consumption curve of the sensor during LowPower mode ?If the 2 second litle larger peak is a particular processing, could it imply a kind of latency before the awaking of the sensor (passing in normal mode, or generating IT), maybe due to the eventual High pass filter ?In advance thanks

At startup I do initializations, then go to STOP1 mode. Initializations include setting a wakeup in the RTC and setting the wakeup clock to the MSI clock. The RTC successfully wakes the MCU. In the wakeup callback, I do some things then start a LPTIM. Then I go back to STOP1 mode. The LPTIM callback is never called. void HAL_RTCEx_WakeUpTimerEventCallback(RTC_HandleTypeDef *hrtc) { /* ********* Called when time to acquire and store reservoir pressure ******** */   // turn on reservoir level sensor power supply HAL_GPIO_WritePin(SENSOR_PWR_GPIO_Port, SENSOR_PWR_Pin, SET);   // LPTIM1 is clocked by a 1 Hz pulse supplied by the RTC // Start 15 minute timer to allow level sensor to stabilize if (HAL_LPTIM_Counter_Start_IT(&hlptim1, SENSOR_STAB_SECS) != HAL_OK) { Error_Handler();   }   HAL_GPIO_WritePin(GRN_LED_GPIO_Port, GRN_LED_Pin, SET);   // HAL_PWREx_EnterSTOP1Mode(PWR_STOPENTRY_WFI); }It is called if I remove the command to go to STOP1 mode as sh

I tried importing a project using STM32CubeIDE V1.4 and got the following error: I tried doing package updates and everything I could think of but I wasn't able to figure out how to resolve this (tried googling/forum searching it but no luck). Anyway, if anyone has any suggestions, that would be awesome. Thanks!

The  x-nucleo-ihm06a1 board power supply by the MCU (3.3v) and the motor power supply by a DC power supply.The pwm1/pwm2/ref_pwm is generating by the L452 MCU (timer6),the EN/M1/M2/STBY pin connect to the MCU pinout.That can't work.I convert pwm1/pwm2 to spwm,that can't work either.And i can't find any solution in manual.please help me,thanks.

Hi,i develop 100% of my code in my workshop or office, but sometimes i wish i could do some very light modification to a parameter or baud or something in the field and i dont really fancy carrying my expensive workstation laptop around. So i wonder if there is an app for android (or ios) similar to stlink utlity, so i could connect st-link debuger via otg usb to tablet and flash new code(modifing can be done easly in any notepad type app) in the field?

Hello,We have STM8S105K6T6C parts with same COO = Malaysia and same date code but some have MSL listed as 2 on the manufacturing label and the others have 3 as MSL. The question is which MSL is the correct one or they are both correct? I couldn't find any document to indicate what MSL should be. Thank you.

HiI have installed the latest versions of STM32CubeIDE and TouchGFXDesigner. How to set a new program as soon as possible?greetingsAndrzej

Hi,I am using the X-NUCLEO-NFC03A1 board with an Atmega328p MCU and atmel studio.I have been trying to communicate with the CR95HF via SPI but I cant seem to get any reply on the MISO line. The MISO line never drops below a certain voltage level (around 100mV). Any idea what might be causing this? I checked that the SCK, MOSI and CS signals all have good integrity on the CR95HF chip. I have attached a picture of the SCK and MISO signals.Thanks in advance for your help

I'm using a X-NUCLEO-NFC03A1 board with a NRF52 as host controller. I'm able to read/write commands and set the chip to WFE mode with Tag Detection and IRQ pulse as WU sources.Now I'm setting it to hibernate and, as far as I understood from the datasheet, it should go from hibernate to active state only by setting the IRQ_OUT pin to low state, and then I'd be able to read the chip response that should return the WU source as IRQ pulse (0x000108).However, I seem to be unable to use the chip once it's back from hibernate state, and it only works again after I send a RESET command. I found this strange as the startup sequence shows it differently. Is this correct or am I doing something wrong?ps. I also get 0x0000 as a first response from the chip, which is also strange as it is not mapped as a valid response in the datasheet for an IDLE command.

Hello,I've been trying to transfer some data from AXI-SRAM to DTCM via MDMA but it seems not functional.The transfer occurs the flag of end of transfer is set yet the data that I have in my DTCM isn't the orignal one contained in the AXI-SRAM.Also important point to note is that I don't have an error flag.I have reduced everything to a minimum but yet it doesn't seems functional.Here is some bits of my code:#define ADC_IN_BUFFER_SIZE 10   __attribute__ ((section(".axi"), used)) uint16_t RandomBuffer[ADC_IN_BUFFER_SIZE]={0x0000}; __attribute__ ((section(".dtcm"), used)) uint16_t samplingBuffer[ADC_IN_BUFFER_SIZE]={0x0000};       void MX_MDMA_Init(void) { //switching on the clock for MDMA LL_AHB3_GRP1_EnableClock(LL_AHB3_GRP1_PERIPH_MDMA);   NVIC_SetPriority(MDMA_IRQn, NVIC_EncodePriority(NVIC_GetPriorityGrouping(),0, 0)); NVIC_EnableIRQ(MDMA_IRQn);   LL_MDMA_SetTriggerMode(MDMA, LL_MDMA_CHANNEL_0, LL_MDMA_BLOCK_TRANSFER); LL_MDMA_SetRequestMode(MDMA

Hello,I am facing random HardFaults on a STM32F722. They happen at various places in code, sometimes even during stack's initialization.Stack's analysis do not show any risk of overflow : most of the time, the problem happens while executing main() loop, and stack's width is never more than 2 levels.Looking at Fault status Registers shows:_ bit FORCED of HFSR is set to 1_ CFSR = 0x1000000 = bit UNALIGNED of UFSR set to 1: unaligned memory access. bit UNALIGNED_TRAP is set to 0Looking around PC and LR, I only see "unoffensive" instructions (typically, ldr, str, or ldr.b and str.b), and the code registered in stack is part of my main's infinite loop, which most of the time executes without any trouble. So I do not understand how it could sometimes trigger a memory alignment fault...!I read https://community.arm.com/developer/ip-products/processors/f/cortex-m-forum/43707/unable-to-determine-offending-instruction-usage-fault-illegal-unaligned-load-or-store-cortex-m7-keil-mdk

Hi!How to set Gpio pin high while MCU is in deep sleep mode to keep power supply on?I cant find any information.

I need to reload view completely after major external changes. I don't want to reset each state manually.What is the correct way to do this? Is this the only way?void MyView::reloadView() { application().gotoMyScreenNoTransition(); }This works fine, but requires custom handles for each view.
