Hi, I want to use the Fast transfer mode on ST25DV64KC. I am using X-NUCLEO-NFC03A1 as a reader. When I write code for fast transform mode in X-NUCLEO-NFC03A1, I get an error. Do I need to make any adjustments in ST25DV64KC? Rgds KU

Hello people, i want to create 4 different PWM signals that has total period of 100 microseconds and working with %25 duty cycle. My timers are working with 50 MHz Speed but it is not necessary to do so. I need them to be shifted 25 microseconds apart from eachother. What i mean by this is actually; PWM1 starts-> 25 microseconds later PWM1 Pulse goes LOW and PWM2 goes HIGH -> 25 microseconds later PWM2 goes LOW and PWM3 goes HIGH and so on. Is there anyway to do this with STM32F411RE/407VG mcu's? I have both eva-boards for those mcu's. I know it will be slight differences between those signals because it is not a FPGA board but i am willing to see what i can achieve with those 2 controllers. Thank you all!

Hello everyone,I'm writing to raise awareness of a potential problem with quartz resonators that could affect clock designs.In your AN2867, you provide a formula for calculating the load capacitances of quartz oscillators.The datasheet for the STM32L431 states that 10 pF can be used as an approximate estimate of the total capacitance of the contacts and board. Does this mean that the quartz must have a nominal load capacitance greater than 10 pF?If the answer is yes, then why is the quartz MC306-G-06Q-32.768 with a CL=6 pF parameter, which is additionally loaded with capacitances of 6.8 pF, used for power consumption measurements in the datasheet?Please share your thoughts in the comments below.Thanks,Maksym

Hi,I have STM32L0x1 svd v1.3, and it seems the PWR_CR LPSDSR bit is missing.Is there a more recent svd file? I can't seem to find it.Thanks

I am trying to update the firmware in the STEVAL-SMARTAG2 using Memory & File editing  in STM32 CubeProgrammer Windows Application., but I get Error: failed to erase Memory.My goal is to install your demo firmware to use the SMARTAG2 with ST NFC Sensor Mobile app.Screen shots and the Log, Verbosity level 3 follow.Note I have Rev A of the SMARTAG2 Thanks,Vince

Hi we're using STM32L412RB controller for our development wanted to know what are preferable IDE that can be used for the software development for the purchased controller.(They've suggested us for Eclipse wanted to make sure is it okay to use eclipse if yes what are the advantages and disadvantages of that)Also need the suitable emulator information/suggestion regarding this? 

I've got a STEVAL-SMARTAG1, and i need to build a React Native App that reads the sensor reading stored in the memory via RF.To do so i'm using "react-native-nfc-manager" library to use the NFC sensor on the phone to read TagData but that doesn't contain any data from the sensor, (it contains only the serial number of the chip).Then i found out that i could access the memory using a method of the library called "transceive" that send a command to the chip and receive a buffer response. I actually using 2 commands:Read Multiple Blocks ( NfcManager.transceive([0x02,0x23,{first_block},{number_of_blocks}]) )Extended Read Single Block ( NfcManager.transceive([0x02,0x30, {block_number(LSB+MSB)}]) )they both work to receive back a buffer which consist of an array of uint8 that i think is the memory value of that block.Now i need to know how to interpret that memory value so i can read the sensor readings that are stored in memory.Is this the correct way of doing so?or there is

Hi there! I just would like to report that enabling the MPU for the M7 core on my NUCLEO-H755ZI-Q, CubeMX (6.9.2, with H7 package version 1.11.1) generates 2 functions:MPU_Initialize() andMPU_Config(). While the second one is declared and defined in the main.c; the first one is just declared and never defined nor used generating a compiler warning.It's simple to fix it by cancelling the useless declaration, but the warning com back any time the code is re-generated... iTTy   Edit: Edited by ST Moderator to add right Label "STM32CubeMX"

hi, This is question regarding UART reception.UART configured with 115200 8 N1 I have a project where i need to receive a multibyte packet on UART and the length is not fixed.My Queries 1> Which approach should I take to receive a multibyte packet.2> Is DMA a suitable in this scenario, DMA generates interrupt only when the number of bytes are received, if the packet size is not fixed how to handle this situation.3> I'm planning to decipher single byte at a time and build the packet as per my protocol requirement Is there any function to receive one byte at a time.4> Is there any way to receive single byte using DMA ?Kindly provide some inputs

HI team,I am using stm32h723/33vgh6 development board. In that i am getting OUT of RAM memory i need to move some of runtime functions in object file to another RAM section from RAM_D1 or merge the RAM partiton into RAM_D1 to overcome from that issue.is it possible to do merging of ram partitions to overcome the issue. i am attaching memory analyzer photo belowplease give some solutions.

STM32H7A3ZIT6QI have a firmware that receives data via UART and responds accordingly at an external side, using a Timer interrupt. When the JTAG is connected, the program works as expected, with all commands being responded to. However, when the JTAG is disconnected, the microcontroller fails to respond consistently or with high frequency. This indicates a possible issue related to the presence of the JTAG interface.I currently do not use WFI() or WFE() in my code, so I assume it won't enter sleep mode. However, I am not entirely sure about this. I am curious to know why the behavior of the system differs when JTAG is connected versus when it is not. I wonder how to approach this situation and what specific aspects I should examine to understand this discrepancy, and How do I prevent this unexpected behavior.

Is there any way to get an overview of the 16x16 (time-integrated) SPAD array signals? I would like to see how the VCSEL spot looks on the SPAD matrix. Clearly, this information must be present on the chip itself, as it knows about its optical center. However, is it also possible to access this data via I2C somehow?

I am definitely in favor of this feature which I am used to with Notepad++ (which they call Smart Highlighting In All Views).If choise Match caseIs it possible to configure CubeIDE to highlight selected text (part of a word), change the Match case of the text? That is, highlight all matches in the text of parts of words?

How to do it?

Hello,I was trying to use USART1 in a project with STM32H742VIT6 but decided to use LPUART1 instead.  I found that using the same BRR computation the baud rate is coming out MUCH slower (it's around a factor of 51 slower).  LPUART1SEL is in the reset state and the prescalers are set the same (D1PPRE, D2PPRE1/2, D3PPRE are all set to divide-by-2) so LPUART1 should be getting the same clock as USART1 was.Is there something fundamentally different in the BRR calculation for LPUART1 compared to USART1?  I can't find anything of the sort in the programming reference...Thanks,-Brian

Hi,I would like to inquire whether it is possible to perform internal I2C and SPI loopback tests on the STM32F767ZI board.Regards,Mounika

Hey,I recently bought ST25-TAG-BAG-UI1 and hoped I could experiment with it for a specific application but I soon realized there is no documentation available publicly. I've applied for access to AN5580 but my application got rejected (I guess because I don't have a website yet and my production forecast is low). How can I evaluate the digital signature functionally of ST25-TAG-BAG-UI1 evaluation board if you are not providing any documentation on commands for it? Is there any other document that would help me to test this?

When I generate code for the MPU region 0 wit HAL I get:void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = {0}; MPU_Attributes_InitTypeDef MPU_AttributesInit = {0}; /* Disables the MPU */ HAL_MPU_Disable(); /** Initializes and configures the Region and the memory to be protected */ MPU_InitStruct.Enable = MPU_REGION_ENABLE; MPU_InitStruct.Number = MPU_REGION_NUMBER0; MPU_InitStruct.BaseAddress = 0x08fff800; MPU_InitStruct.LimitAddress = 0x08fff900; MPU_InitStruct.AttributesIndex = MPU_ATTRIBUTES_NUMBER0; MPU_InitStruct.AccessPermission = MPU_REGION_ALL_RO; MPU_InitStruct.DisableExec = MPU_INSTRUCTION_ACCESS_DISABLE; MPU_InitStruct.IsShareable = MPU_ACCESS_OUTER_SHAREABLE; HAL_MPU_ConfigRegion(&MPU_InitStruct); MPU_AttributesInit.Number = MPU_REGION_NUMBER0; MPU_AttributesInit.Attributes = MPU_DEVICE_nGnRnE | MPU_WRITE_THROUGH | MPU_TRANSIENT | MPU_NO_ALLOCATE; HAL_MPU_ConfigMemoryAttributes(&MPU_AttributesInit); /* Enables the MPU */ HAL_MP

Hello all, I'm learning about Nucleo F746ZGT6 . and also I'm doing some projects related to this board. I want to ask how much digital voltage & Current at the one pin of Nucleo F746zgt6. 

HI,I am working on a custom STM32MP151AAC3 board, and working on OpenSTLinux 4.10 distribution package.Now I can connect to the board through UART4(PB2 and PG11) by STM32CubeProgrammer, and I want to tune the DDR3 to verify the design. I need the u-boot-spl.stm32 binary file.Firstly, I create a custom layers for the custom board following the instruction from https://wiki.stmicroelectronics.cn/stm32mpu-ecosystem-v4/wiki/How_to_compile_the_device_tree_with_the_Distribution_Package , and I can built the system image successfully. But I cannot find u-boot-spl.stm32 or u-boot.stm32 in the **/deploy/images/customboard/u-boot directory.Then I find a wiki page said that “The ouput file u-boot.stm32' is only generated for stm32mp15_trusted_defconfig with CONFIG_STM32MP15x_STM32IMAGE; it is not more used for ecosystem release ≥ v4.0.0”. So, I adjust the machine.conf and append "UBOOT_CONFIG[trusted] = "stm32mp15_trusted_defconfig,,u-boot.dtb", still cannot get the u-boot stm32image.I have attac
