I would like to ask for advice on how to modify text wildcards generated by pure code that cannot be displayed in Chinese. English is displayed normally.My personal feeling is that the font does not support Chinese, but I don't know where to set it in pure code

Hi,I am testing a VL53L4CD sensor for a measurement application. I am using the example code from the API to test out the sensor and I'm having an issue with the minimum distance of the sensor. It will not report a measurement range less than 70mm and when the target is closer than 70mm it reports range status 3. The API documentation says that range status error 3 means that the distance is below the detection threshold but has no other information about the error. I have tried changing the detection threshold to 0 with the API function (VL53L4CD_SetDetectionThresholds) but it had no effect on this error. I don't see any other information in the API manual that appears relevant, but this API doesn't seem to have as much documentation as the APIs for other sensors (I have used the VL6180X a little bit as well, with no issue). Any help with this is much appreciated.

Hello, What is the VIL(Low Level Input) voltage of the IC M74HC14YTTR provided VCC voltage 3.3V?The datasheet specifies the VCC voltage levels of 2.0V, 4.5V, 6.0V. We have used the VCC as 3.3V. 

Pictures got lost during migration, too, for example:   JW

Hi,What am I missing ?The connection to the event source is grayed and non selectable, see screen copies of the configuration below.  

Hi,I have an STM32H573I-DK Discovery kit with me. I wanted to try out Edge AI applications on it, and was checking out the STM32Cube.AI Developer Cloud. When I reached the "Generate" section and browsed through the listed boards, I could not find any of the STM32H5 series MCUs listed. Is it because they are not supported?Will I be able to use it if I use X-Cube-AI with CubeMX?

Dear ST community,                                 I am facing an issue with the virtual COM port for my NUCLEO-F070RB board. It is not working on my Windows 11 computer, and I am not sure how to resolve this. Can you please provide me with some guidance or solutions to this problem?   Thanks and Regards, Santhosh

I want to use the IWDG watchdog with the maximum possible time delay of approx. 30 seconds. As the device cannot be switched off, It has to go into standby mode (HAL_PWR_EnterSTANDBYMode) instead.  The issue here is, that the watchdog would wake it up after 30 seconds. Therefore I want to make the IWDG faster just before going into the sleep mode in order that it comes up again and then going into sleep mode a second time but without setting the IWDG. My Question: Can the IWDG be triggered immediately or make it expire faster if it is already running?

I am evaluating the ASTRA1B demonstration board. I powered up the board, with factory firmware, via USB and attached an STLINK-V3MINIE debugger/programmer to the J300/STDC14 connector on the expansion board to a PC running TT.Output to console worked fine. Noticed LoRa radio was broadcasting at EU868.I am US based, so I need to configure it to use US915 band.I started a new STM32 project and imported CustomUC source code into CubeIDE.Used CubeMX to configure FP-ATR-ASTRA1 -> Parameter Settings -> STM32WL_SUBGHZ_REGION to US915.Built and flashed the board. - No console output. Tried different baud rates, 9600, 115200. No console output.I have used this setup to build, flash and run a LoRa Nucleo-WL55 board without problems.After some online research, learned that UART configuration is in the STM32_WPAN section of IOC.Tried enabling CFG_HW_LPUART1_ENABLED, which was disabled. Re-flashed the board. No console output.I tried hacking the code in main() to call DBG_PRINT

I have purchased the SensorTile.box Pro from Mouser, and the device is excellent to work with on coding. I have loaded 0x0000000 with bin file default from F:\ST_SensorTile_Box_Pro\STM32CubeFunctionPack_STBOX1_V1.5.0\Projects\STWIN.box\Applications\DefaultFw\Binary\DefaultFw.binThe SensorTile.box Pro does not work and is unable to access the Android to start the Dice or Compass demo.How can I get the SensorTile.box Pro back on the day I purchased it on July 27, 2023.Best Regards,Rob

I read RCC RSR to determine the cause of reset. It is not clear to me the purpose of RMVF bit. I guess it resets the other flags but why would I want that ? I wonder if I am missing something.

What is the maximum clock source frequency can I use as an external clock for timer?I have a 20MHz source and PLL frequency made out of this source. The purpose - generate lower frequency pulses that synchronous to that 20MHz clock with controlled delay. I can get 100MHz, 120MHz, 140Mhz, 160 MHz out of that PLL for delay of less or more precision and would like to know what will I be able to get.It could be easy made with FPGA, but since ST got such high speed MCU, I hope I can do it just with a MCU. MCU will be needed anyway.

Hi People,I need to know what will happen when I forget to set the clock configuration by using system clock configuration function. Is there any default clock configuration will set in the microcontroller when I forget to set clock configuration?I'm raising this because I can able to feed the complied code which doesn't have a clock configuration. And still I can able to debug the uploaded code with stm32h7.

HelloIn STM32G474RET6 I want to have 2 banks. Bank 1 for golden (boot image) and Bank 2 for an application image.As I want to have a robust solution I always want to boot from Bank 1 (address: 0x8000000), to check if valid firmware exist in Bank 2 (address 0x8040000) and if ok to jump to Bank 2 and to run firmware stored there.My code based on FLASH_DualBoot example of STM32Cube_FW_G4_V1.5.0 is working ok, but it is not good enough for me as it toggle the boot between Bank 1 and Bank 2. Where I can't find simple example code that will simply jump to Bank 2 from Bank 1 (and still remain boot from Bank 1 after next power up)? Thank you. Alex

Wanted to know the available evaluation board for the for  STM32L412RB controller.

Hello, I've tried measure period of  GPS PPS which is very high accuracy. I'm using TIM5 input capture mode, reset slave mode. The TIM5 CCR1 gives value 208877646 that is wrong because I use high accurate generator for sys clock. The right value is about 209000000. So maybe anyone meet the problem? Thanks,Alex.

Hi,How to get number of glyphs in a font ?numGlyphs variable is not accsesible in GeneratedFont (linked with application) neither in BinaryFont (installed from .bin). Or is it ?// from GeneratedFont.hpp namespace touchgfx { class GeneratedFont : public ConstFont { public: GeneratedFont(const GlyphNode* glyphs, uint16_t numGlyphs, uint16_t height, ... ); ... } class BinaryFont : public GeneratedFont { } Thanks, Ferro

Hello everyone.Is there a way to generate the report files (pdf and txt) via command line in CubeMX?I run STM32CubeMX in command-line mode getting commands from a script,but I didn't find any commands about report generation in the command line summary table.Greetings

Hey,I am using the Nucleo-G474RE board with the X-Nucleo-NFC08A1 NFC Shield and use the X Cube NFC6 library in the Cube IDE environment. The initialization seems to work and there are no errors when building the code, but the demoCycle() function doesn´t work. It can only get into the state DEMO_ST_START_DISCOVERY and then breaks out of the switch function and if I comment out the break of the case it reaches DEMO_ST_DISCOVERY but the if statement gets an error and again breaks out of the switch statement. I can´t find the source of the error and don´t know what to do anymore. The gNfcDev seems to be in the wrong state and doesn´t change to the right one. Can someone please help me?

Dear ST I tried to connect with MCU "stm32l07x using STM32CubeProgrammer as below image 1, image 2. Board power is 3.09V to be measured by ST-Link.However, I can't program it.  carefully check the st-link pin maps as VCC(#1), SWDIO (#7), SWCLK(#9), RST(#15), GND(GND). In here (#1), (#7), (#9), (#15), (#GND) is for 20 pins header. VCC/ SWDIO/ SWCLK/ RST/ GND is for ST-Link. Please hint me on how to trobleshoot for it. Thanks advance.Best Regards, Kevin, 

Hi GFX Team,When I collapse a text group in Text View, it is not remebered by GFX Designer for next run ie all groups are always expanded after Designer start. Could you implement this please ? And maybe add 'collapse/expand all groups' in the mouse right click popup menu ?Thank you.Ferro Befor GFX close.And after new GFX Designer seession start. 

Hi. Everyone.I'm trying to control external MUX using a GPIO pin in the STM32WB55 microcontroller.Because of a limited number of PWM pins, I'm trying to use a GPIO pin for continuous regular switching.My question is that even though the company said a maximum of 45 MHz (or 9 ns) is possible for the GPIO pin my code does not work properly (mux doesn't switch well without a 1 ms delay).The mux speed is a possible maximum of 100 MHz. So, I do not doubt it's performance but it may be due to the too fast swithing of GPIO pin.I need at least 1 us (1 MHz) switching speed. So, I wonder how can I give 1 us delay to the GPIO pin properly using IDE code?  

What does the word “Q” mean in the NUCLEO board, for instance, in “NUCLEO-H755ZI-Q”? How is it related to the MCU? Sorry for my ignorance, I’m new in the stm32 world.
