We're starting the development of an Android application based on NFC Tags, so to ensure compatibility with a wide range of smartphones I'd like to know if you have a table of compatibility such as presented on the website below for the Tags ST25TA family:https://www.shopnfc.com/en/content/7-nfc-compatibilityKind regards

Hi, I have shared my project schematic. it's should work or not? (SMPs not used)Problem : BLE cannot advertise, but this configuration in STM32CubeIDE can work with NUCLEO-WB55.

Hi,I'm building a mobile application that integrates with ST25DV64KC and M24LR04E-R.The maximum number of blocks is fixed at 256 for a "Read Multiple Blocks" command on a ST25DV64KC chip.The maximum number of blocks is fixed at 32 assuming that they are all located in the same sector for a "Read Multiple Blocks" command on a M24LR04E-R.Is there a command that returns the maximum number of blocks that can be read at one time, or is there a way I can learn which model of chip I'm reading, so that I can read the correct amount of blocks in a "Read Multiple Blocks" command. I can see some NFC Tag applications show an IC type which displays the model but I am unsure as to how to retrieve this information myself. Any help would be gratefully received.Kind Regards, Sam

Any HW or SW solution?

Hi , i have a couple of questions.Doing initialisation every first power on may cause any error or latency  ?Which clock source use when RTC is powered on VBAT ?Thanks any helps

Hi!Is there anyone could explain how we could set this register to get better range?Thank you.Regards,Albert Tseng​

Dear Sir,I am porting RFAL now. Based on 5.8 in UM2890, for HW chip selection, macro ST25R_COM_SINGLETXRX should be set. In st25r3916_com.c, the following code declared a local buffer. #if defined(ST25R_COM_SINGLETXRX) && !defined(RFAL_USE_I2C)static uint8_t comBuf[ST25R3916_BUF_LEN];               /*!< ST25R3916 communication buffer                 */static uint16_t comBufIt;                       /*!< ST25R3916 communication buffer iterator            */#endif /* ST25R_COM_SINGLETXRX */I can understand why such local buffer is need. Is it dependent on some host specification which provide single byte access? If I use a host that support

I have a BLDC Motor which is rated to run at 14S, but the ESC only supports 6S. Can I simply remove the Capacitors and the 10V Buck Converter to something capable of the higher Input Voltage. I'd also swap the VBUS Voltagesplitter to compensate.I would leave the Mosfets, as they are capable of 60V and I'd supply it with up to 58.8V.Is there some complication I am not aware of?Any help is much appreciated

I have a project that contained UI design using TouchGFX. Almost the code auto-generated by TouchGFX for STM32CubeIDE is lay on QSPI external flash. And after built in CubeIDE, I saw .bin file of project around ~2GBSo, I try to relocate all the section pointed to QSPI external Flash to Flash region by using Linker file. After that, .bin file have been built around 900KBSo what is the problem here? why the code lay on QSPI ExtFlash made the ".bin" file too large?

Hello,I am working on the USB DFU for a STM32H7A3ZGT6I have two projects one for the DFU and one with the application to be updated.My application works fine when I download it with the debugger.The DFU part manages to erase and program the new app to the flash (I read it back with the ST link and there is no error nor address shift)However, the app doesn’t work when it is loaded by the DFU program. I jump from the DFU app to the start address of the application which starts but seems to crash at random moments during execution (from seconds to minutes)I have set up the app start app address in the DFU to #define USBD_DFU_APP_DEFAULT_ADD    0x0800C000UThen in the app software I have made the following : In the FLASH.ID:           FLASH (rx)    : ORIGIN = 0x0800C000, LENGTH = 970KIn the system_stm32H7xx.c: #define VECT_TAB_OFFSET 0x0000C000UL I suspected the interruption vector of the DFU app

I'm using the STM32WLE5JBI6 part which has 128kB Flash and 48kB SRAM but it is not clear what address these have as the STM32CubeMX generated linker and header files is for the 256kB Flash and 64kB SRAM partAm I correct in thinking the layout for this part is as follows:Flash start address: 0x08000000 length: 128KSRAM1 start address: 0x20000000 length: 16KSRAM2 start address: 0x20008000 length: 32KIf so this is quite strange as the SRAM memory is no longer contiguous but I can't see anything that says otherwise

Hi,Imagine I want to write the same string in two screens with a font X, with a font Y in another screen, and with a font Z in three other screens, how should I go about it with the current text management that offers touchgfx? Should I just create various resources like TEXT_1_SMALL, TEXT_1_MEDIUM and TEXT_1_BIG that all have the same text and a different font ? What's the best way to go about it?What I do as of now is shown in the following image: I just use the resources to define the style of the texts and then, I have a separate table with all the traductions, which allows me to print a same text with various styles. What I don't like is that by doing that, I have to bypass the 'touchgfx way' of managing texts.So the question is : is there a way of doing that through touchgfx without having to have multiple resources with the same text just because they have different fonts… ?Thanks in advance.

Good morning,I am trying to setup STM32CubeIDE to work on an offline computer, I do not have the option to connect it to the internet. Installing the SDK through the IDE works fine and I am able to import the OpenSTLinux source projects (Linux, U-Boot, TF-A/SP-Min and Op-TEE). but this is not what I need.What I really need is to have the same result in an offline environment, this is what I do:1) Install OpenSTLinux SDK via script as explained in the Developer Package instructions.2) Install STM32CubeIDE 1.8.0/1.9.03) Configure STM32CubeIDE Preferences menu for "STM32Cube->OpenSTLinux SDK Manager" to point to my SDK installed in step 1 4) Install FW Package for stm32mp1From this point I am able to create projects and compile for stm32mp1But I am not able to import the OpenSTLinux Source projectsI am working with the stm32mp1 MPU (stm32mp157f-ev1 board) and I tried using STMCubeIDE 1.8.0 and 1.9.0 versions with the same results.How can I install offline the SDK so the STM32CubeIDE is

FP-CLD-AWS1 software package v3.0.1 for STWINKT1B fails to be compiled in higher STM32CubeIDE version than 1.8.0. Library link error happens. It is successfully compiled only in 1.8.0. version. It seems to be IDE bug. I hope it to be checked and fixed.

While trying to debug the program I get the following error:CM4 Failed to read all registersFAILED to REGISTER Values from the targetWhat should I do?

The function we want is that it automatically recognizes when a small object with an NFC tag is mounted on a device.Thus, We want to have an NFC reader on our device and attach NFC tags to small objects to mount on the device.Is it possible to use ST25R3916B as NFC reader to read Ntag213?If it is possible, how can I get some samples?Best RegardsCho

hello.I am using LSM6DSM to collect acceleration and gyro data.Data is being collected at 52Hz using FIFO, but the actual data collected is about 51.2Hz.It is probably caused by the LSM6DSM internal clock being inaccurate. Is there a way to correct this?For reference, my MCU's clock is set very accurately to the external clock.I need help. thank you

Hey guys, I was wondering if someone made the onboard High Speed PHY to work on the STM32F730Z8? No matter what I have tried, I am not able to make it work on HS. I am trying to implement an MSC host to read a USB memory stick. It is working without problem on the OTG FS port, but when i reconnect the usb connector to the HS pins (PB14/PB15), nothing i have tried so far has made any progress (3 days now). Most basic setup from stm32cubemx wouldnt have any effect at all when the memory stick is connected. I implemented the VBUS control thru a switch chip, as well as defined the output GPIO so that HAL can control that pin, and this works fine on the OTG FS.I have a 3k resistor connected between ground and the USB_OTG_HS_REXTPHYHS pin. The USB connector is getting the proper 5V. The only time I had a different outcome is when i explicitly added __HAL_RCC_OTGPHYC_CLK_ENABLE(); at the HAL_HCD_MspInit() function. After adding this, the gState of the u

Setting the encoder functionality on STM32F103C8 is straight forward, just set the registers that's due. But on STM32F407VE it seems more tricky: using PA6 and PA7 on TIM3, if you follow what is said in the RM0090, page 616, you're not ready to go:Further, I've discovered I had to configure the AF function to the pins 6 and 7 and then attach AF to TIM3 setting AF2 to register GPIOx_AFRL on pins 6 and 7: The question is: where in the RM0090 is said to set the AF to enable encoder functionality?(On STM32F103C8 it's not necessary to attach TIM3 to AF, you simply have to follow the recipe, unlike for the STM32F407VE).Would this section of RM0090 be a simply copy-and-paste from RM0008, where it works flawlessly?

Hello,I am reading out of the book, "Embedded Systems Fundamentals with ARM Cortex-M Based Microcontrollers - A Practical Approach Nucleo-F091RC Edition, 2nd Edition. (DEAN)."He reviews the peripherals on the NUCLEO-F091RC and goes into detail on how to provide specifics on this board w/ the STM located on it. Anyway...I am using studio.arm.keil to produce some source onto the board by building and then flashing it.
