Hi, I want to understand, Is it possible to license STLINK-MINI to use on our stm32 mcu based custom evaluation boards(commercial purposes) ? If possible how do we proceed about it to get the licensing cost , terms and conditions. Thank you

Hi,seems like TouchGFX Designer is unable to create a compilable folder structure for TrustZone-enabled U5 projects. So far the workaround is to use a separate non-TrustZone project and then manually sync all the changes made by TouchGFX Designer back to TrustZone-enabled one. This is very inconvenient and error-prone way to do work.The ST stuff has been made aware of it and the answer was "We are working on it". TouchGfx version was 22.0 that time. Is there any progress on this matter?  Seems like recent TouchGFX updates didn't fix the problem.Thanks.

Hi everyone. I set a flag, and checked it in handleTickEvent of any page. I give new location to images when the flag is set. I have a problem in this point. Sometimes(approximately 1/50 flag set), i see random color on some pixels. I research this problem at now. Do you have any idea about this problem? If i can find source of this problem, i will think the solution. I need to ideas about source of this problem. I have take many photos about this problem. You see that in following SS.Info:STM32G0B1EXT FLASH IC Best regards,

Hello,please I need a confirmation about RDP level2 and WRP combination on stm32g031 chip.Based on RM0444.Rev5 Table 19, if I use my own bootloader and I write-protect the flash sectors, I have to avoid activating RDP level2 or I'll loose the opportunity to update any firmware (application and/or bootloader itself) even from inside the microcontroller.Is that correct?If it was correct: so why, generally speaking, one should go with RDP level 2 when RDP level 1 is enough to prevents useful data to be read-out from the main flash?Just to avoid any firmware update from the outside world? Thank you

Hello,Is there any documentation or source code to use ULPL with USB3343? Even I am not cleared USB3343 chip could be used for external High-Speed USB support to STM32F407. Or suggest me any chip with low complexity, I aim to achieve high-speed data transfer from PC to Memory to stream ADC Data and DAC data.

Hi, when I inserted keyboard/mouse to USB host port, nothing happened (log console) and this even cause usb host stop working then.But when I inserted keyboard/mouse to a hub and connect this hub to usb host port, everything working fine.The problem is only happened with hid (keyboard/mouse). When I used USB thumb drive, it works just fine, no need the hub.The chip I used is STM32MP153 and this is custom buildDoes anyone know why or any hint?Thanks.

Hi guys, I'm using RM0421 as reference for my develop work.But find some error in Chapter 5.1 Table 6.The end address of 256KB Code Flash block 4 and block 5 should be 0x0113FFFF and 0x0117FFFF.Is that correct? Kind regard! 

For the VL53L4CD,Is there a default ranging frequency that can be set to the highest ranging frequency of 100Hz?How to set ?

Hi.I am using SDMMC1-eMMC(16GB), SDMMC2-SD Card connected on a custom board.Both eMMCs and SD-Cards use FatFS as their file system.Both work fine when used alone.However, if you use f_open or f_write on FatFS on eMMC, you sometimes get an error and the FatFS becomes unusable afterward. My settings are as follows.  I tried to find the cause by disabling all device drivers and features and then enabling them one by one.The problem I found was that FatFS on eMMC often caused problems if the ability to receive UART data via DMA was enabled. void MPU_Config(void) { MPU_Region_InitTypeDef MPU_InitStruct = {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 = 0xD0000000; MPU_InitStruct.Size = MPU_REGION_SIZE_16MB; MPU_InitStruct.SubRegionDisable = 0x0; MPU_InitStruct.TypeExtFiel

STM32WB55RGV MCU is in use, and BLE_HeartRateFreeRTOS example is under review. In the example of BLE_HeartRateFreeRTOS, it was confirmed that the STOP2 mode function was included, but I don't know the Stop mode entry conditions.And I wonder if I can set the BLE ad timeout in the BLE_HeartRateFreeRTOS example.Or let me know if you have any documentation that explains this example in detail...This is because I want to know information such as current consumption in STOP2 mode.

Hello. I am trying to modify my s19 file which is generated for stm8 using stvd and cosmic c compiler. Consider an S19 file which starts from 0x4000 address [EEPROM starting address]The first two lines would be : S123400000000000000000000000000000000000000000000000000000000000000000009CS123402000000000000000000000000000000000000000000000000000000000000000007CI want to know what is the meaning of the first characters S123 and the last byte 9C/7C etc. This is important for me to understand the logic to modify the s19 accordingly.  

With its latest policy to download Cube IDE, I tried to firstly give my email and received a link via email from STM. But the link turned out to be dead (no response at all). Then I registered an account and logged in. This time clicking "Get software" kept me hanging. (a forever loading page before accessing available software.) Does anybody have any solution on it? 

The ST60A3H1 looks very interesting. While I understand an NDA is required for access to the complete details on this solution, would it be possible to say if it works underwater as communication between ROV modules?Scenario:IC A | 1mm air or mineral oil | 5mm plastic | ~5-10mm (sea) water | 5mm plastic | 1mm air or mineral oil | IC BWould this work at all? Even when only working at lower speed (for example USB FS / 12Mbit) this would be interesting.

I have a LSTM model which was quantized using TensorFlow dynamic, full and float16 quantization. After that, I wanted to benchmark these three quantized models on the STM32AI model zoo. But after importing these models into the web UI and pressing "Start", I get the following error message: >>> stm32ai analyze --model dummy_model_0_stateful_int.tflite --allocate-inputs --allocate-outputs --compression none --optimization balanced --series stm32f4 --target stm32f4 --name network --workspace workspace --output output Neural Network Tools for STM32 family v1.7.0 (stm.ai v8.1.0-19520) NOT IMPLEMENTED: Unsupported layer types: READ_VARIABLE, VAR_HANDLE, ASSIGN_VARIABLE, CALL_ONCE, WHILE, stopping. I would be really grateful for ideas or insides on the problem :) 

Hello,I evaluated the VL53L5CX and it works pretty well. Unfortunately I cannot use it in my application because it has a RAM based firmware (flash memory consumption and maybe boot time also).1) Is there a way to easily find out which of the sensors are RAM / ROM based?2) Will there also be a ROM based version of the VL53L5CX?

Hi everyone, I'm using a STWINBX1.Some documentation say that RTC can be plug to Vbat. In my case, my board won't be plug to current and will only work with a battery.My question is simple, is RTC can "remember" date and time if the battery run out of energy ?I read that some RTC on modern computer can work without battery, with a crystal. But I can't find a similar information for my board.Thanks 

Hi.A custom board was built using the STM32H753XI. The board contains 16MB SDRAM and we want to use it with an LTDC to display a screen on a TFT-LCD.I used the embedded wizard to create the UI and verified that it displays correctly on the LCD screen.However, flickering occurs on the LCD when the screen is switched or parts of the screen change.I rechecked the clock, SDRAM, LTDC settings, etc. but couldn't find the cause.I've attached the datasheets for the parts I used as files. 1.

Hi Please can you advise on the Thermal Resistance (K/W) of LSM6DSOXTR please so we can complete our ATEx evaluation. Many Thanks Dominic

The problem is pin PB4, which is always powered.It is the same as returning to "STM32CubeG4_Demo_NUCLEO-G474RE.hex".Do I need to send it in for repair??How to send??  

Hello,LIS2DH12 accelerometer. AN5005 datasheet. How is the data in the table in column 1 (Acceleration values) calculated? (See Figure 1). I read the calculation process in the datasheet above, but did not understand it. (See Figure 2).

Hello ST community, I am leading a project at university and I would like to make a communication between two STM32WL55JC1 cards using the LoRa protocol without a gateway. I'm not very familiar with STM32CubeIDE and any help would be much appreciated.The aim is to recover data from an accelerometer that will be transmitted by a serial communication to the first STM32 card and then make a wireless communication to recover the data on the other card. First of all, I would like to know if I can make a communication between two LoRa device without using a gateway. Thanks for your answers. Jules.

Hello all, We will probably need to go for custom cover panels for our sensors, however, we could not find a clear list of requirements to follow.Material: The product's datasheet (DS13812 - Rev 6) states that "the VL53L4CD achieves the best ranging performance in various ambient lighting conditions and for a wide range of cover glass materials." We were considering PMMA or PEI + PC as Gilisymo's / Hornix's cover panels for the VL53L4CD use these materials. Are there other materials worth considering?Thickness and air gap: We came across AN5231 - Rev 1 that provides cover window guidelines for the VL53L1X sensor (not the VL53L4CD).  In Section 5.2.6 ST states that "for sub 1000 mm ranging– Total air gap and cover window thickness = 2 mm maximum– Cover window thickness <1.5 mm and air gap <0.5 mm"Is this also valid for the VL53L4CD, or are the recommended air gap and cover window thickness values different? Please let me know if there is document

Hi, I have configured an LED for RF field status in the rfal_plafrom.h.The LED switches on when rfalNfcDiscover() is called. But the LED does not switch off when the rfalNfcDeactivate(RFAL_NFC_DEACTIVATE_IDLE); function is called. This function returns RFAL_ERR_NONE and I am expecting the LED to switch off. How can I confirm if the RF field is off ? Why does not the LED turn off ?RFAL library used is 2.8.0    

How can I measure the sleep current of the chip on the STM32F103C8 board? 

HelloI am trying to powerup external 8MHZ crystal on STM32F407VET6 MCU but it is completely dead. I run the LED bliking program using HSI, and it is working sucussfully. Boot 0 and Boot1 pins have been PD with 500 ohm.  I also run the same code to use HSE on STM4 Discovery board after removing R68, I see HSE on board is working. Below are my caclulationFrequency = 8 Mhz,Co = 7 pF ( as per datasheet)CL= 10 pF ( as per datasheet, used 20pF CL1 and CL2) ESR = 100  ohm ( as per data sheet)After calculation gmcrit comes..gmcrit = .287 gm =  5 ( from ST data sheet)gain margin = 5/.287 = 17    so gain margin > 5 condition is met. I also changed Rext  to 0, 100, 200, 500 , 1000 ohm. HSE is dead. PCB design seems ok , and I assume for now no issue with PCB design.I have gone through AN2867, but not sure what point I am missing.Kindly suggest where could be the fault.  I eliminate software issue as same code is ma
