X-CUBE-EEPROM v5.0.0 includes a sample for NUCLEO-STM32L552ZE-Q.I am trying to use this sample for STM32552CCT6 to run EEPROM Emulation, but the EE_Init() execution results in an error.To begin with, is it possible to operate EEPROM_Emulation with STM32L552CCT6?

Regarding P/N: STM32WB55 in a WLCSP100 package:Q1: When VBAT is not in use, can I connect it to GND?Q2: When VDDA is not in use, it must be connected to VDD, but is it still requires a 10 nF + 1 μF capacitors?Q3: If VDDA is not in use, can I connect VREF+ to GND?Thanks!Nir

I've just downloaded 2.13 but I am unable to find release notes for it looks like these were not updated yet?My real question is if Internal ticket number: 144023 was addressed within that release

I used the ST25R3911-DISCO Board GUI and C++ DLL demo to utilized the ISO-DEP function to read from and write to an NFC-B card. How do I go about doing this with the X-nucleo-NFC05A1 on Nucleo 64 using arduino IDE? I need help getting started on writing a function to poll, select card, read and write to that card. Thanks,-E.

I am new to TouchGFX, I ran into a problem that using TouchGFX 4.21.1 on STM32H743Eval 2 , I add a global variable (e.g. counter) within "USER CODE BEGIN 0", , in StartDefaultTask, add counter++ in the main.c file, follow MVP design procedure, just want to dispaly counter value in TextTArea widget, CubeIDE code compiling is ok, but when click "run simulator", it appers "C:\TouchGFXProjects\STM32H743\TouchGFX/gui/src/model/Model.cpp:13: undefined reference to `counter'I am also using 4.18.0 of touchgfx, both have same symptom, is there any setting I missed, please help, thanks in advance.

Hello,I'm using the ADC on a STM32G431 to read 5 voltages at 20kHz. Everything works well, but suddenly the 5 channels "get stuck" or freeze, i.e. the value they measure becomes constant even though the voltages on the input pins still fluctuate. Sometimes the measured values resume to being correct again by themselves after a little while (like after 200 samples for instance), other times the values remain constant until I manually cycle the MCU power.Some more details about the code architecture:I use 5 channels of the ADC2 in single-ended modeThe sequence of 5 regular conversions (Single conversion mode) is triggered by TIM2's TRGO (update event at 20kHz)Data is stored in an array by DMA in circular mode. In the DMA ISR I have code to copy and log this data (at each DMA transfer complete interrupt).Some info about my debugging so far:I've enabled ADC overrun interrupt and checked that it never gets firedSame goes for the DMA transfer errorWhen logging the data I also log a

After changing some properties, those are: -"BOR_LEV" set up 1 (BOR Level 2 VBOR2 brownout threshold level 2) -"RDP" set up CC (level 2 chip protection) from "Option Bytes" segmentation in STM Cube Programmer(It was unintentional case and before this fault, I have no problem in coding my MCU), the MCU(STM32F7xx) can not be seen any STM program anymore. If I should give some information about schematic design, -BOOT0 is pulled down-nRST is pulled up and goes directly programmer GND pin-PDR_ON is pull-up.Now, actually I dont know anything about RDP & BOR_LEV of option bytes. How can be turned back the situation for me? Do you have any advice?

How to implement LTC4015 with Stm32L072 MCU, I want to charge the battery through LTC4015 using I2C. Can you please suggest me how to use this in stm32 microcontroller. 

When DMA is used, the MX_DMA_Init shall always be called before any other HAL_***_Init (where *** is any peripheral with a HW dependency on DMA init code).A regression was detected in the previous STM32CubeMX version 6.3.0 (STM32CubeIDE Version: 1.7.0 ) generating a wrong order of initialization functions.This issue was fixed in the latest STM32CubeMX version 6.4.0. Thus, newly created project with this version will generate the correct initialization functions order.Because the calling order is saved into the ioc file, the misplacement call to MX_DMA_Init() remains the same when trying to migrate automatically an old project from a buggy old version to the fixed version. The order stays the same and the generated code will be unfunctional.For any old ioc file created by any STM32CubeMX version up to 6.3.0 included, hereafter some steps to overcome this misbehavior:Open the saved .ioc file (already created with 6.3.0 version) with any text editor installed in your machine and delete th

I'm starting to use the NUCLEO-WB55RG dev board but can only find a 'databrief'. Is there somewhere I can find a more detailed 'datasheet'? Something that shows which pins are connected to what on the board? Hopefully some address mapping as well for embedded C applications. TIA

I have configured the STM32CubeExpanision_Crypto_V4.0.1 folder using the STM32CubeIDE. Within the folder is a main.c file for a SHA256 digest located in ..STM32CubeExpansion_Crypto_V4.0.1\Projects\NUCLEO-L476RG\Applications\Hash\SHA2_Digest\Src. Within that file, there is a string of text for a message, and a string of text for the expected hash. However, I have typed in the text online in a sha-256 digest calculator and the generated hash value is not the same as the one in the main.c file. I have CRC enabled but I do not understand why the expected hash value in the main.c file is not correct.Below is the string of text for the message and expected hash value.Below is the string of text for the message and expected hash value in raw form Msg = 6b918fb1a5ad1f9c5e5dbdf10a93a9c8f6bca89f37e79c9fe12a57227941b173ac79d8d440cde8c64c4ebc84a4c803d198a296f3de060900cc427f58ca6ec373084f95dd6c7c427ecfbf781f68be572a88dbcbb188581ab200bfb99a3a816407e7dd6dd21003554d4f7a99c93ebfce5c302ff0e11f26f83

Hello,I am using the TouchGFX application to display data gathered from CANbus communication, which I have verified is working. One feature I wanted to have is the following logic for fault error codes:If a fault is present, display the error code in hexadecimal (with a user manual to outline the meaning of said error codes) in red.If no fault is present, then I want NO text to be present. I do not want to show "0x00000000". I just want no text to be there at all.I've attached a snippet of my code that writes the value into the wildcard currently. This solution does not work. void Screen1View::UpdateFaults(uint64_t value){ if(value != 0x00000000){ Unicode::snprintf(textFaultSigBuffer, TEXTFAULTSIG_SIZE, "%x", value); } else{ Unicode::snprintf(textFaultSigBuffer,TEXTFAULTSIG_SIZE, "%x","" ); } // Invalidate text area, which will result in it being redrawn in next tick. textFaultSig.invalidate(); }Instead of displaying a blank space, it shows 8031650 (like in the picture).

I have an STM32F469NI-DISCO (AU1) board, and I need to put a big array (representing a GIF) in the external flash. I created a code attribute at first, and stored this array under the attribute in the external flash, but it won't work: the linker makes the new memory location appear in the compilation summary in the STM32Cube IDE project.So I tried with the linker generated from another project that was using TouchGFX, and I put my array in the external flash, but again, nothing.Attached the project file. The array is called "animatedLogo", and is located in the zlogo1.c file. I also redeclared all the macros used in TouchGFX (although I am not using touchGFX here).I am also aware that the memory configuration in the Init() is not complete, but here the issue is a the compile time. But one step at a time...

I have a STM32H745I-Disco board which is still not supported. If I use an STM32H750B-DK example from TouchGFX (same board except mcu) I can download it from the designer and run it on the board. When I move the code to CubeIDE I can compile and download the code from CubeIDE. After reset with the Ex_Mem_Boot programmed in flash I can reach main. Stepping through the code it seems to crash at ret = HAL_RCC_ClockConfig(&RCC_ClkInitStruct, FLASH_LATENCY_4); when it enables the sys clock.Martin any idea? How long away are we to have the heavily advertised STM32 tool set supporting all mcu's? :)

Hi,My project is based on STM32L15xx microcontroller. I know, that internal FLASH Read Protection may be enabled during programming an image by STMFlashLoader with --erp option. My question is: can I compile my image with internal FLASH read protection enabled by some tweak so that I don't have to use "--erp" option on downloading my image to the target?Thanks in advance!

Hello,I bought NUCLEO F401RE + X-NUCLEO-GFX01M2 and am learning TOUCHGFX. In TouchGFX4.21.0 design, there is no reference design for this configuration.Are there any sample projects for NUCLEO F401RE + X-NUCLEO-GFX01M2?If no, how to generate code with STM32CubeMX to support TouchGFX (NUCLEO F401RE + X-NUCLEO-GFX01M2)?In TouchGFX designer, how to create a project without a reference design, for example NUCLEO F401RE + X-NUCLEO-GFX01M2?Best regards,Jiannong

Dear ST Team ,How do we add more antennas port and multiple tag reads from 200 to 500 ) ...!Model :ST25RU3993

Hello everyone !I am writing to you because I cannot increase the transmission distance of my ST25RU3993-HPEV kit. I have bought the ST25ru3993-HPEV kit with two antenna, ...I read that with the External PA I can increase the transmission distance but I can't do it. What is External PA ?It does not work with External PA but in Internal it works but the distance remains limited.I use the antennas from the kit and here are my settings:

Hi There, I'm trying to use the STM32H743Zi2 nucleo board for test purpose. I configured the board with default settings ( when asked by CubeMX after selecting the board for a project). Means i basically did nothing (except assigning 1 ADC ppin and leaveing the rest untouched). I then tryed to configurate the Clock to use the 480MHz advertised in the datasheet, but Cube MX seems to be willing to accept only CPU Clocks below or equal to 300MHz. There seem to be a rounding problem while setting up the PLL values, as in the ioc file they appear to come out with decimal values that don't exist.main problem is still that even if setting values way below the 480MHz, CubeMX doesn't accept anything above 300MHz ( according to the hint given while hovering the error with the mouse)I had that problem once with another board, and had no other choice than restarting the project from the scratch, but that didn't work out that time. Cube MX is up to date(v6.7.0), and MCU Package also ( v1.11.0 for

Hello ST-Community,I have two NUCLEO64 STM32WL55JC1 development boards and am trying to get the LocalNetwork example up and running. A build can be easily generated from the LocalNetwork_Concentrator in the CubeIDE and transferred to the board. On the other hand, the LocalNetwork_Sensor shows a malfunction. The build cannot be completed successfully because the includes "demo_package_format.h" and "version.h" fail. When examining the firmware package manually, the files could not be found either.Is the error due to an incorrect procedure on my part, or were the required ST include files incorrectly not provided in the firmware package?Attached is a screenshot of the error message in the STMCubeIDE.I use the following software:STM32CubeIDE 1.11.2STM32CubeMonitor 1.5.0STM32Cube MCU Package for STM32WL series V1.3.0
