We use ST25NFC_Embedded_Lib_ST25R3911B_1.5.0 for our current project.There are some example inside.In all example in stm32l4xx_hal_msp.c are the following code:/* Configure all GPIO port pins in Analog Input mode (floating input trigger OFF) except debug pins */GPIO_InitStruct.Pin = GPIO_PIN_All & (!(GPIO_PIN_13|GPIO_PIN_14));GPIO_InitStruct.Mode = GPIO_MODE_ANALOG;GPIO_InitStruct.Pull = GPIO_NOPULL;HAL_GPIO_Init(GPIOA, &GPIO_InitStruct);GPIO_InitStruct.Pin = GPIO_PIN_All & (!(GPIO_PIN_3));But & (!(GPIO_PIN_ should be & (~(GPIO_PIN_Please fix this in next release.

While trying to disable TZEN on a NUCLEO-WBA52CG boar after running the GPIO_IOToggle_TrustZone Example an both LEDs working as expected i encountered the error Error: ST-LINK error (DEV_TARGET_NOT_HALTED)after switching from RP Level 1 to RP Level 0 and deactivating the TZEN Option bit

Hi @Brian TIDAL  @Rene Lenerve  @JL. Lebon Can you please help me understand how antenna size in st25dv64kc tag effect the reading range and another question is like in iso15693 tag reading range is 60cm but practically working with tag my experience  the effective range of communication  between  tag and nfc enabled phone is 6cm why is this?

Hi, st team,mcsdk: 6.2.1control board: nucleo-g474reBridge: XNUCLEO-IHM09M2Power Board: STEVAL-CTM009V1We're going to buy around 10k-25k uc per year.1. STEVAL-CTM008V1 schematic diagram defines that it is possible to use 3 ICS. 2. X-NUCLEO-IHM09M2 circuit schematic Fig.1 defines that PhC current can be obtained via MC19(PC0) I've assembled STEVAL-CTM008V1 with 3-rd magnetic current sensor.Could you please advise how can it be achieved?1. Can I configure 3-ICS reading via workbench?2. If I clone STEVAL board, is it possible to configure the current sensing to read the 3-rd sensor? 3. Should I modify firmware sources, generated by workbench? Appreciate in advance,Taras.

Hi everyoneI'm now using D6T-44L Omron sensor to measure Temparature, i read the User mannual as the below After that, i write my own code in IDEi use I2C_Scanner to check the device at which address is ready, here are my code and my result through UART to PCIt seems everything is okay but my return value is always 255 

Hello everybody,for first time flash programming of private CAN bootloader i want to use the ST bootloader.Despite of the nBoot_SEL Bit i can flash data if the flash is empty.The bootloader mechanism is shown in Figure 55 in the AN2606.Now the questions :1. Do i have to set valid level for e.g the RXD pins of UART 1 and 2 and 3 or are the internal pullup R used ?2 During scan of all possible interfaces, see Fig. 55 in AN2606, are the corresponding output pins (e.g. TXD pins) of the interfaces in Tri-state ?E.g. UART3 is used for flash update, is it possible to use TXD of UART2 for input, that means an external driver circuitdrives into TXD of UART2 ?3. If i use FDCAN, do i have to use FDCAN1 (PD0 and PD1, AN2606, Table95) or FDCAN2 (Manual, 2.5, page68, pins ?) ? Thanks in advance,BR, Kai 

Hi, I am new to stm32 microcontroller. I am finding difficulty to render my html page using azure rtos. As I have seen the example of stm32f429zi nx_Webserver.

I created my own html page in my project I am using stm32f439zi. I am not able to render my html page. Not getting how to create bin file.i followed the procedure as given in the fileX document. Still can not figure out.please help me

 we are attempting to read wristband mifare classic tag using NFC03A1NFC03A1 is able to detect the tag UID.when we execute ndefPollerReadBytes().. directly, we get ret = 04 (ERR_TIMEOUT)need some sample code to read this tag...from your forum i understood that we need to perform authentication before we can read/writehttps://community.st.com/t5/st25-nfc-rfid-tags-and-readers/st25r3917-mifare-license/m-p/232467we prefer ndefPollerReadBytes/ndefPollerWriteBytes() to store data directlykindly suggest the rfal call sequence with examples.. PS: used android nfctool application to read the tag.

Hi，I have two questions about the SPAD:1: How does the L4CX select which part to turn off and which part to turn on when the signal is so large that the SPAD needs to be scaled down? Because i have a Lens installed on the light receiving area,  I'm worried if the spad  turn off  the signal-sufficient part .2: Is it possible to adjust my SPAD area by ROI? The manual of the L4CX says that this function is not supported, but I found the API function . Below I would like to explain the problem I'm having:In order to increase the  signal at the far end, I installed a spotlight lens on the light receiving part.I then noticed that when detecting the appearance and disappearance of white objects in close distance, the data returned by the L4CX was not very stable, with continuous error reporting and data abnormality.I found that when the anomaly occurred, both the signal and the spad were abnormal, so I suspect it was caused by the spad opening position.I've

Hi, ST community.I'm trying to drive a motor using Nucleo-H503RB. At that time, I am trying to change the USART pin of STLINK and connect it to Motor pilot, but it does not connect.＜Detail＞I want to use PB14 and PB15 for the STLINK USART pins instead of the default PA3 and PA4 (because I use PA4 as DAC).I changed the Nucleo-H503RB json file for Motor Workbench and solder bridge (SB2&SB3→SB18&SB22, SB19&SB33→SB20&23) to change the USART pin. In Motor Workbench, the USART pin has been changed from USART3 to USART1. However, it does not connect to Motor pilot.（Defalut setting (PA3 and PA4) were worked correctly. ）The software I use to generate F/W is Motor Workbench 6.2.1,  EWARM V8(but debug in V9), CubeMX6.10.0, STM32Cube_FW_H5_V1.1.1.I will send you the Workbench file, json file I was change, and EWARM F/W file that I used.  

Hello everybody, I am currently designing a configuration utilizing two drivers to heat a mat, which is a resistor load requiring 24V and 3.3A. This component is commuted at 100 Hz. For this setup, I've employed two different drivers: the first one being VNB14NV04TR-E, utilized for switching large loads requiring high currents. On the other hand, I've utilized the MIC5018 to control the spoken driver. Additionally, I have add a pull-down resistor to force the 0 state, and I may use a series resistor for the PWM signal to limit the current, although I am not sure about it.... We have conducted tests of this configuration on one STM developmentboard, and it appears to be functioning properly. However, we would like to confirm if the setup is correct, as we have connected this system to a developed PCB with STM32h563, resulting in sparks and the MCU failure. The diode is a recent addition to the design; initially, we believed it might not be necessary due to the resistor load, assuming th

Hello community, I am using STWINKT1B board and trying to implement basic accelerometer datalogging from scratch. I don't want to use HSDatalog because I don't need so many functionnalities.I am using FATFS functions, able to use mount, mkfs, mkdir, open and write functions to create this file DATA/data_000.TXT.When I add the f_stat (after mount and mkfs) function with the path "DATA/data_000.TXT" and restart the board, I always get a FR_NO_FILE error. If I put the SD card in my laptop I can see the file in DATA/data_000.TXT:Here is my code:Any idea about what could cause the issue ?Thank you 

I am developing a device with the STM23MP153C and plan to implement secure boot, but I don't fully understand the SSP workflow and have a few questions.1. The STM32CubeProgrammer documentation says that the -ssp command can be executed both with HSM and with a generated license. Do I understand correctly that this is the license that must be generated by the -hsmgetlicense command of STM32CubeProgrammer? If so, the license is valid only for the current device?2. Is it mandatory to have HSM in production? Is it possible to generate a license for production so that production is not dependent on the presence of HSM? STM32CubeProgrammer program has a command -hsmgetlicensefromcertifbin. Is this command not what I want? If so, it requires "Input certificate file path" as an argument. How can I generate it?3. HSM has a certain licenses count. Is this license per flash process or per device? Can I flash the same device multiple times with one license?

I have one of P-Nucleo-WB55 and recently bought one more P-Nucleo-WB55 board.We are using this board to program the STM32WB55VG6YTR microcontroller in our custom board and we have succeeded more than 20 times in programming that microcontroller using ST-LINK in P-Nucleo-WB55. However, recently we couldn't access either our microcontroller in the custom board or the dummy microcontroller in P-Nucleo-WB55 anymore. In addition, we never succeed in using the new P-Nucleo-WB55 board. After several trials, we found that the wire length of SWCLK was the reason.Right now, we only can access the dummy microcontroller in P-Nucleo-WB55 using a jumper pin to connect SWCLK. If we use a normal wire (resistance < 1 ohm), we cannot access even the dummy microcontroller.This problem is big because we have to program the microcontroller in our custom circuit board. Does anybody have a similar problem and find a solution? 

Hi people, I'm trying to use the flash crc but is not working as expected. If I pass the end address with offset 3 or 7 the result of crc calc will be always the same, 0xba4bbbf0. What the problem here?   FLASH_CRCInitTypeDef flash_crc_init = { .TypeCRC = FLASH_CRC_ADDR, .BurstSize = FLASH_CRC_BURST_SIZE_4, .Bank = FLASH_BANK_2, .Sector = FLASH_SECTOR_0, .NbSectors = 1, .CRCStartAddr = FLASH_BANK2_BASE, .CRCEndAddr = FLASH_BANK2_BASE + 7 }; uint32_t flash_crc_result = 0; if(HAL_FLASHEx_Unlock_Bank2() == HAL_OK) { HAL_StatusTypeDef hal_status = HAL_FLASHEx_ComputeCRC(&flash_crc_init, flash_crc_result); }   The address has this values:  

good morning   i was trying for sometime now to configure stm32 timer as a counter to count the pulses in order to count the RPM of a rolling gear and then show it on a lcd screen, and no matter what i do or change in the code or the timer configuration, the number of pulses is always stuck at 0. can anyone please help me with it? i really need it for my studies. (by the way, i am using a proteus simulation to test it).

I am working with the above device. I have created an .IOC file and auto-generated code. I can see the GPIO configuration for the simple I/O, but I do not see any pin configuration for the ADC inputs that I have selected. I assume that I will have to add these to the MX_ADC_Init module.I have attached the .IOC file that I have created.

Hi, I'm developing an application, which require ADC channel changes when an analog watchdog interrupt triggers. Now in my IRQ routine, I'm having issues with consistent interrupts triggering, blocking my code outside of the ISR intended to change my channels and run my application. Is there any way to stop this from happening ? I've tried __disable_irq(); with no luck. And utilizing __enable_irq(); as well. What I want to do is, prevent all the other interrupts occuring while I am in the ISR, control the flow of the code. I can't use scan mode scanning multiple channels or the DMA, this is the only way for my application to work. Thanks,   

Hi,I recently started exploring what STM32WL MCUs offer but I don't really understand a few things yet:1. I read somewhere that these STMs are based on SX126x LoRa radio. Is that the case?2. If so, does enabling "SUBGHZ_PHY" in middlewares in CubeIDE allow me to control this built-in radio with some simple HAL functions as if i was controlling a seperate LoRa module connected via SPI/something else?3. Based on questions 1 and 2, can I communicate between 2 STM32WLs with LoRa as if I was using simple separate modules?4. Can these STMs communicate with normal SX126x based modules? If so, with what chips exactly?5. What are the differences between STM32WL55 and STM32WLE5?I'm sorry if these questions have been answered before but either I didn't find them or I just wanted confirmation.Adam

Hi @mƎALLEm,I need to develop a unique serial number for one of our products that will go into production soon. I'd rather use the UID that is built into the STM32H7A3 chip but I have some questions.I understand that it is a 96bit value that I can read from the chip but I'd rather not have to use such a long and unwieldy number.I looked at page 2920 of the manual RM4055 but it doesn't really tell me which byte is for which variable (Lot, Wafer, Die, etc).This number will need to fit onto our 7" display as well as the serial number label on the product's back side.Has anyone else been able to figure out the UID format?Thanks,Richard

Other than reserving pins for the hardware-implemented debug interface (Fig. 1), what are the effects of the highlighted settings of the "Trace and Debug" category of CubeMX (Fig. 2)? Fig 1: Debug infrastructure (RM0433) Fig 2: CubeMX Trace and Debug Changing those settings has no effect in regard of code generation. How would one utilize i.e. External Trigger Bi-directional? I would have expected the system to halt (essentially triggering a breakpoint) on a signal change of the reserved TRGIO pin when activating this setting - but nothing happens. The same is true for the other direction, triggering a breakpoint does not change the value on the TRGIO pin. The same goes for the setting Trace Synchro SW (x bits). SWDIO and SWCLK can be used to communicate with a debugger, but TraceD0 seems to do nothing? I could not find an answer in the datasheet as referenced by Table 595 in RM0433. 

Hi,I have a Nucleo-F767ZI board, and am trying to configure it to use its LEDs, USART3 which is the virtual com port of the ST-Link on the board, and eth, I added LWIP, but I am unable to enable the LWIP_SOCKET as it requres to enable LWIP_NETCONN, by looking through the "General Settings" and "Key Options" with "Show Advanced Parameters" checkbox checked, I did not get a clue on how to do it.   RegardsChao
