Hello everyone,I have a project in mind where I want to create a business card with an NFC tag that redirects to my portfolio page. My main concern is ensuring that the NFC tag URL redirect works on as many phones as possible. I've heard that Type 5 tags don't work on Android versions above 9. Is this true? Does anyone have any advice or recommendations on which NFC tag I should choose?Btw the NFC tag must include an Energy Harvesting feature so I can show off some cool things.Thanks in advance,Hessel

Hi EveryoneI am starting to use FreeRTOS but faced an issue if there is someone to help. I configured USB_FS MSC. when I use MX_USB_HOST_Init(); the FreeRTOS stop and not working. but when I disable it, everything is fine.I have used the USB_FS MSC in Super loop on mode without any issue.

Hi!I'm using an STM32H723ZG with the STM32 HAL. Ethernet is enabled (and LWIP is correctly configured and working fine). I'm trying to get the STM32's MAC to automatically reply to PTP SYNC messages using the PTP Offload feature. I've configured the MAC using the HAL_ETH_PTP_SetConfig function and then manually set the MAC's MACPOCR POEN bit, however no packets are produced. I'm trying to configure the STM32 to be an Ordinary Slave Clock so that it responds to SYNC messages. SYNC messages are correctly being sent on the network by my Master Clock (a linux workstation) however they are not causing the ethernet MAC on the STM to respond. I have several questions. What should I program the MACSPI0R, MACSPI1R and MACSP2R registers to? Should it be programmed to the Clock ID of my Master clock? Should it be a unique ID for the slave clock? PTP is configured with the following structure:(The eth_hclk is at 260 Mhz) ETH_PTP_ConfigTypeDef ptp_config{ .Timesta

Hello, I'm using a STM32G0B1RE and a nucleo SRC1M1 in order to charge and communicate with a tablet in power delivery mode with 5V 3A. I followed the following tutorial: STM32StepByStep:Getting started with USB-Power Delivery Source - stm32mcu (stmicroelectronics.cn) from STM, at first it kinda worked, I had a connection with the tablet in the traces with it confirming it does take 5V and 3A as well as the IN SOPs:002 H:0x0041 GOODCRC message but since it was connected on a hub, it kept turning on and off. So I took the cable for the ST off the hub and directly onto the computer (the nucleo is receiving 5V 3A from an external source) but since then when I go on the board selection and connect the tablet, it keeps disconnecting. I checked, there doesn't seem to be any loss of voltage, so I'm quite lost as to why the board doesn't want to connect with the app.I also changed the STM32, changed computer, changed cable between the tablet and nucleo, nothing changes. I haven't

As I find that the qt layer has been removed from the ditribution package, and no qt ducumentation on wiki is available, does that mean qt is not supported for the stm32mp series?

Hi STM32 friends,I'm about to learn something new, because I hit a problem with STM32CubeMX 6.11.1 (newest)I have used Ethernet on several M7 platforms, not always without a bit of struggling.However, this time after configuring ETH, LWIP remains grayed out.I'm using a NUCLEO-H755ZI-Q, which has an M4 and M7 core. I use the M7 core for ETH.There are no warnings at the ETH configuration, except:"The ETH can work only when RAM is pointing at 0x24000000"So I modified the First Tx Descripter Address to 0x24000200, and First Rx Descripter Address 0x24000000.(I guess they were wrong at first: 0x30000200 and 0x30000000)The warning remains nevertheless.The problem is LWIP remains grayed out.The M7 DCache is enabled (as well as the ICache).I configured the MPU:Region 0:Address: 0x24000200Size: 16KBSubRegion: 0x0TEX: level 1Access: ALL ACCESS PERMITTEDInstruction: ENABLEShareability: ENABLECacheability: DISABLEBufferable: DISABLERegion 1:Address: 0x24000000Size: 256BSubRegion: 0x0

Steps to reproduce are pretty simple:1. In "Pinout & Configuration", open "Middleware and Software Packs". Select "ThreadX". Enable "Core".2. In "Project Manager -> Advanced Settings, change all drivers from HAL to LL.3. Click "Generate Code" from Project menu.4. Compile generated code.Result:../AZURE_RTOS/App/app_azure_rtos.h:31:10: fatal error: stm32u0xx_hal.h: No such file or directoryFile stm32u0xx_hal.h is expected, however it is not generated, because no HAL driver is chosen.

I use the STM32CubeIDE program on Mac (Version 1.15.0)The MCU is a STM32H743VIT and its configuration is done from the *.ioc file.I use ADC3 with an Oversampling of 128.Its configuration is done by entering 128 for the “Oversampling Ratio” line, and the ADC3 initialization code in the MX_ADC_Init() procedure includes the line:hadc3.Init.Oversampling.Ratio = 128;I've just updated to 1.15.1 (with migration), keeping the same files (*.h, *.c, *.ioc).When I open the *.ioc file, the ADC3 settings contain an error for the Oversampling ration: 128 is in red and I have to put “Oversampling ratio 128x”.The initialization code generated becomes:hadc3.Init.Oversampling.Ratio = ADC3_OVERSAMPLING_RATIO_128;No problem a priori, but the code is now compiled with an error:error: 'ADC3_OVERSAMPLING_RATIO_128' undeclared!

So as the subject says, my LCD works correctly when attached to my F407 Discovery board and using SPI2.I am now using a F405 and SPI1 on a custom PCB. I have configured the SPI1 the same as SPI2, basically copied the settings.However I need some advice on the clock speeds and settings. When I use the LCD on the discovery board it will run at low speeds - 10MHz.For SPI1 ton the F405, the maximum speed is lower at 42MHz. Which clocks do I need to set and what speeds do I need for each clock?Using an oscilloscope reveals that I am gettting signals from the MCU on all the relevent pins. My guess is a timing issue of some sort......I know that the MCU is functioning correctly, flashing programs and debug work as normal.Any suggestions or help much appreciated. Thanks in advance

Hello,I have done a big mistake. I was testing a provisioning using the system bootloader. For that I have changed the provisioning batch files. As a result I have set the product state to closed, before the keys where loaded.  Now I can not connect to the target and the standard regression does not work. Is there a way to get the device working again? Best regards,Roman Here the log:10:48:50 : Start Debug Authentication Sequence10:48:50 : SDMOpen : 602 : open : SDM API v1.010:48:50 : SDMOpen : 603 : open : SDM Library version v1.1.010:48:50 : open_comms : 495 : open : Asserting target reset10:48:50 : open_comms : 499 : open : Writing magic number10:48:50 : open_comms : 509 : open : De-asserting target reset10:48:50 : open_comms : 561 : open : Communication with the target established successfully10:48:50 : discovery: target ID.......................:0x48410:48:50 : discovery: SoC ID..........................:0x00000000_38363236_33325117_003D005E10:48:50 : discovery

Previous I2C EEPROM chips had (eg) 3 address pins A2..A0, where you could hardware the I2C address. This allowed up to 8 devices on the same I2C bus in case you need more storage capacity.With the M24M01E this is no longer the case : the device can have it's I2C address programmed in a special settings page, but no longer via the A2..A0 pins But how can I use more than 1 of these devices on an I2C bus ?Do I need to program the chips before soldering them onto the PCB ? 

Hello!I'm working with STM32G0B1 MCU and using CubeMX, I've enabled RCC_MCO for PA9 pin (HSI 16 source, 128 as prescaler) and a simple Input for PA8 pin. The code was generated to CubeIDE and "SystemClock_Config" function calls this method at the end: HAL_RCC_MCOConfig(RCC_MCO1, RCC_MCO1SOURCE_HSI, RCC_MCODIV_128); But I noticed that both PA9 and PA8 outputs 0.125 MHz, even "MX_GPIO_Init" function setting correctly the pins!Searching on HAL files, I found that "RCC_MCO1" defines to "RCC_MCO_PA8", so CubeMX should config MCO as "RCC_MCO_PA9".Can we confirm this as a bug?

I have a problem with handling multicast frames. I think it's a server side problem and how to read multicast frames in the lorawan stack? The same as unicast frames? I added support for multicast frames in TTN according to https://www.thethingsindustries.com/docs/devices/configuring-devices/multicast/. Is there an example? Multicast frame support with server?

I am trying to use the X-NUCLEO-IHM07M1 motor development kit with a custom FPGA pwm controllerI am just trying to spin a motor in open loop and no feedback or speed controlI am planning to feed the 3 phase pwm signal to IN1, IN2 and IN3 and supply 9v to the IHM07M1 board.Im wondering what else i need to take care of , any enable signals to be toggled ?what is the role of ENx signals are they to be toggled with the INx pins ?

Dear  STM：        We have the following questions to consult：         ①Does the PA10 of STM32MP157AAD3T have a pull-up resistance inside the OTG_ID pin function?Do I need an external pull resistor when doing OTG ID function at the same time?If so, what is the resistance value of the external pull-up resistor?        ②What is the maximum capacity supported by the emmc chip attached to the EMMC interface of STM32MP157AAD3T?       ③When the emmc interface of STM32MP157AAD3T supports the speed of HS200, what is the power supply mode of the external EMMC chip? Our power supply method is shown in the attached picture, please help evaluate whether it can be satisfied. If not, could you recommend the design schematic diagram of EMMC supporting HS200 speed？     ④Could you provide the reference design of STM32MP157AAD3T？  &

Hi,MCU planned to use - STM32U5G7VJT6QPlanning to use PD12,PD13,PE0,PE3,PC7,PE5 as encoder and hall sensor pins as shown below in the image.But these signals are 5V logic. Is it okay if we give 5V to these pins?In datasheet it is mentioned as 5V tolerant pins(FT_h). Does it affect its performance? any AC/ DC characteristic issue will rise because of this. Please confirm.Or suggest which pins can be used or any other alternate way. Also the possible failure cases.  

Hey there,im currently trying to debug a small project, where I use a Timer to Read 5 ADC values every second and store them to an array via DMA.While debugging, I couldn't figure out how to display an array in the expression viewer. I saw some videos which suggest, that the IDE automatically detects an array when entered in the expression, but that isn't the case with me.As the flash memory of my mcu is rather small, I have to build the project with optimization to build without errors. I tried -Og, -O1 and -Os, which doesn't affect my problem.If anyone has an idea how I could fix this, I would be very happy. I'm attaching my code from the variable declaration and a screenshot from the expression viewer.If i missed to provide any important information, please let me know.  /* Private define ------------------------------------------------------------*/ /* USER CODE BEGIN PD */ #define ADC_BUFFER 5 #define REFVOLTAGE 3000 /* USER CODE END PD */ /* Private macro -------------

Hi, can someone help with ADS124S08 SPI ADC and its linux driver? I think the driver is correctly probed. I see /sys/devices/platform/soc/44004000.spi/spi_master/spi0/spi0.0/iio.device0/in_voltage0raw ...etc but it seems the device does not reply.This is my device tree configuration:&spi1 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&spi1_pins_a>; cs-gpios = <&gpioz 3 GPIO_ACTIVE_LOW>; #address-cells = <1>; #size-cells = <0>; adc@0 { compatible = "ti,ads124s08"; reg = <0>; /* CS #0 */ spi-max-frequency = <1000000>; spi-cpha; reset-gpios = <&gpioi 2 GPIO_ACTIVE_LOW>; }; };First, i don't see the cs going low when i try to read the voltages. Should the driver do that?Second, the driver ti-ads124s08.c itself seems a bit incoherent with the datasheet. it defines the start conversion command as in the datasheet but then never uses it and instead it uses a made-up command.#define ADS124S08_CMD_START 0x08 #def

Hello everyone,I want to develop a project for STM32MP1 using stm32cubeIDE Version: 1.15.1. In the yocto-related part of the topic, I successfully compiled a kernel and produced an SDK for the relevant kernel. I want to import this SDK into the cubeide environment and start with a ledBlinky application. But I couldn't import the SDK.I have reviewed what is explained in forums and blogs, but I constantly encounter error messages. Below is the location of the .sh file of the SDK I produced.                                                And I keep getting the following error. What I want to do is to use my own SDK for mickledore, not the SDK offered by ST.Sinceley

I have an STM32F407 Discovery board. My project works fine using the dicovery board.Now it is time to move it to my own PCB, using a STM32F405.As a board "bring up" I tried to run a simple LED toggle program. When I flash the program I get a Download verified successfully message.It does not work unless I step through it in debug mode. In run mode the output pin for the LED stays high. If I add a variable and increment it every time the LED toggles I can see it incrementing normally in debug mode.I have an external resonator crystal at 8MHz. I can see it working at 8 MHz on the scope.I have a 10K resistor pulling BOOT0 to ground. The two VCaps are present. A 10k resistor pulls NRST up to 3.3v rail.All power and grounds ok with decoupling caps.I have checked all settings in my .ioc file. Cant see any issues. (The settings are the same as for my discovery board program that works correctly).Im sure one of you can help. Thanks in advance...
