Can ST25R3911B write on tags? Or it is only a reader?Regards.

My stm32l4 discovery kit iot node b-l475e-iot01 stopped the connection via connector 8, I couldn't do it at all, so I used ST-LINK V2, I got communication, but I can't use the USB again, I didn't touch the hardware, absolutely nothing.

I am using STM32F429 in my project which connects to an ATmega2560 thru UART. In arduino, there is a function Serial.Available() to check if the serial buffer is empty or not.Is there a function in STM32 that is similar to Serial.Available() in Arduino?BTW, I am using HAL libraries in STM32CubeIDE and HAL_UART_Receive(huart, pData, Size, Timeout) to read the contents of UART buffer.Please help. Thanks!PS. I've read the documentation in HAL library but I'm not sure if there is one. I've looked into HAL_UART_GetState but Im not sure.

I am using STM32H745ZI for a personal project. Page 60 of the attached datasheet from ST says there are I/Os that are floating unless otherwise specified. I want to use an I/O that I can guarantee will be in either low or high state on a reset or if the processor stops working. My goal is to find an I/O that I can be certain will be in a particular state (high or low) at reset or if the processor is not working but has power.Any help is appreciated.

Deer electronicians,I was following the video "STM32 – Creating a File System on a SD card" from the ST Youtube channel.I done stricty the same things as in the video but an error occurs.../Core/Src/main.c:22:10: fatal error: fatfs.h: No such file or directory 22 | #include "fatfs.h" | ^~~~~~~~~ compilation terminated.I tried to enter manually the include path for all the files concened but many new errors are rising.My config :STM32F746-DISCO (the same as in the video)STM32CubeIDE 1.6.0Firmware F7 1.16.1Windows 10 64 bitsI stay reachable for any questions or precisions.Cordialement,François

Are additional external circuit components needed to reliably connect USB voltage to an ADC input, besides a voltage divider that brings 5V down to 3.3V?

Hello,so I am trying to set up a INA3221 current/voltage/power sensor with my STM32F469I-Disoc board. The I2C_adress ist 0x43 (or 0x86 if shifted left). I set up my I2C with CubeMX in 400kHz mode and already used to interact with a BME280 sensor. The interaction with this sensor works without a problem, however it uses 8 bit registers.The INA3221 sensor has 16 bit registers. I am just getting startet and wanted to check/read the value of the configuration register (0x00) after writing my own config to it (config value: 0x7FFF).I guess I am doing the write operation wrong but I dont quite now what to change:extern I2C_HandleTypeDef hi2c1;   typedef struct { uint16_t checkv; }INA_DATA;   INA_DATA INA;   //Initialization of the INA3221 void INA3221_Init(void) { HAL_StatusTypeDef status=HAL_OK;   uint16_t mycfg=0x7FFF; //All channels enabled, 1024 averaging samples, 8.2ms BV CT, 8.2ms SV CT, and all continuous measuring //uint16_t mycfg=0x7927; //All channels enable

We are using STM32L5 Nucleo board and TZEN is enabled and DBANK mode is enabled too..!How to switch dual bank mode to single bank mode in option bytes(if any h/w or s/w changes)??Please explain the procedure to understand what are the changes needed to be done before I uncheck DBANK option byte in Cube programmer...?

Hello,​I've confirmed my registration on feb 25th, but today i got an email stating my ​registration can't be confirmed. Is this an error?​

Hello,I just received an email from ST; I registered for the 30 March workshop but due to reached capacity my registration was not confirmed. I would like to ask if there is the possibility to join the workshop on another day.Thank youAlessandro

I'm considering changing from STM32F723ZEI6 to STM32F723ZET6.[Question]・Is there a problem when I run the same program?・Does they have the same functionality?

Hi, so basically I am looking to source the IMU LSM6DSM. I see that it is out of stock almost everywhere. Is this device being discontinued? Why is it so hard to purchase?If you have a more in-stock variant, with the same pinout, please let me know. I see that there are a bunch of LSM6DSxxxxxx variants but I'm not clear on what the differences are. They do have separate datasheets which worries me.My overall design criteria is:Very low power (must operate on coin cell)Vsupply = must stay alive below 2.2VI2C interfaceWakeup on movement interruptNeeds to be physically very smallLow costI may be willing to change to a different / more recent part if there is a compelling reason (such as stock shortages...)

Is there a way to use the HAL library to read the variable specified in the address?

I check the options for a servo stepper project - either special controllers like Trinamic - or using standard processors. Coming more from general embedded scene (including ST32F411 based grbl Controller), I would need guidance in motor control specific things beyond the basics. MCSDK looks very promising in this. But I can only find non-stepper related documentation so I wonder if MCSDK is capable to support bipolar sensored FOC scenarios at all for non-rocket-scientists. Can somebody point me to existing information about servo stepper possibilities at STM - ideally application note or tutorial ?ThanksPeter

I would like to use a SMP controller such as L6726 or other as a boost regulator. That is use the high side output (pin PHASE) connected to 0V and my boost transistor. I would use the low side driver to drive a MOSFET as a synchronous rectifier Is this possible alternatively are there any spice models I can used to try this option?Apologies if I have already posted this but i could not find the post? 

Hello,my project expands and i need more than 32k flash.In the CubeMX it is not possible to change the Mcu Referenc.It is possible without to generate the project new to change the Mcu?Thanks

Hello,I made a minimal project with the NUCLEO-H723ZG board, in which I also used SWO printf. The project is all about generating and writing out a random number every 500 ms in the main cycle. Debugging in STM32CubeIDE with ST-LINK/V3 and J-Link Edu also provides completely invaluable data. Although I only use ITM channel 0, DWT-Comparator data is displayed in LOG ... ??? The MCU clock is 400MHz and the SWO divider has also been carefully set. I did the same project on a NUCLEO-H743ZI2 board (the newer ST-LINK/V3 release) and it works perfectly with ST-LINK/V3 and J-Link EDU as well. I extended both projects with SEGGER RTT printf and tried to debug with Ozone:Only RTT is visible with NUCLEO-H723ZG, SWO also works with NUCLEO-H743ZI2. At this point, I rule out an error in the STM32CubeIDE or ST-LINK/V3, the problem must be somewhere in the difference between the two MCUs. Software versions used: J-Link V6.98a, Ozone V3.22b I attach the two .elf files, both loaded into RAM. Thank you v
