Hi Sir, I'm looking for the data sheet and programming guide for the STWLC38JRM to develop the off-line programming algorithm. Would you please share such information for reference. Thank  you. 

Greetings! So, I used the OpenBootloader project, and then flashed a GPIO_IOToggle firmware in other area of the flash, close to the example in the video Introduction to Open Bootloader, Part 3: Loading an Application.  In that example the CubeProgrammer flashes through the DFU and check "run after programming". When I unplug the board and turn it back on, the OpenBootloader starts (as expected). What I want to do is, as soon as I flash the application, when I turn off the board and turn it on again, the application starts to run and not the bootloader, OR, it starts the bootloader, it checks if there's any application installed, and if yes, it jumps to the application immediately. Any clue on how to do that?Thank you! 

Hi, We have two ST60 eval boards and we are trying to configure them for test.  The boards arrived with no documentation, and there are a lot of jumpers that we can set.  We are trying to get either a user manual for hte board or the schematics so we can determine what we need to set / configure in order to get it operational. Thank you,WillST60 Eval Board

I'm developing an ios app and a need to present a password to write a protected block. I use the custom command 0XB3 that i allready used in the equivalent android app. Unfortunately without success. So I tried with the custom command menu of the NFC tap st app, The custom command, with android work and with ios NO. see the attached pictures. I hope someone can Help me..

When I select IO pin swap in CubeMX, the LL SPI initialization code does not update the pin swap register.Using H5 Nucleo board and LL HAL.  Easy workaround if you know to look for it. 

Hello everyone.How do I update the firmware via VCP on STM32F407VET6? Is it possible to do so? If so, what needs to be changed and added? Do I have to recreate the bootloader?I don't know where to start here.Thank you :)

Hello,I'm developing a Qi compliant product (Not getting Qi.) using STWLC38JRM.Please respond on Operating Frequency and ASK modulation cycle to get back to the testing agency.[Operating Frequency]Qi standard defines the operating frequency from 110 kHz to 205 kHz.Is it possible for STWLC38 to set (limit) operating frequency?Or does it depend on the settings of the transmitter (e.g. STWBC86)?The CFG file is provided by the customer, so I don't know the detailed settings. However, using "STSW-WPSTUDIO V2.2.5",I have confirmed that "OP FREQ" shows approximately 139 kHz when charging in BPP.[ASK modulation cycle]I believe STWLC38 sends an ASK modulated signal towards the transmitter.It seems that the signal is transmitted from STWLC38 in the digital ping phase,but how often is it transmitted during charging in BPP?Isn't it sent at fixed intervals during charging?I understand that each communication bit of the signal is synchronizedwith the

Hello Team   I have a general query.    Do we have any 555 timer with ASIL-B or ISO26262 compliant.    I am interested in discrete level solution rather going with MCU and my aim is to have redundant control/ feedback/LIMP HOME mode embedded in the 555 timer so that i can achieve functional safety requirement.   Thanks Kesavan

Are the X-NUCLEO-IHM08M1 motor driver board and the NUCLEO-H533RE development board compatible?I noticed "STM32 Development Boards Portfolio", but I’d like to confirm compatibility before proceeding X-NUCLEO-IHM08M1 | Product - STMicroelectronicsNUCLEO-H533RE | Product - STMicroelectronicsThank you

Hi,Could you please let me know if you’re planning to provide an example of a USB Audio device based on USBX in the near future?By the way, the ST X-CUBE-AUDIO package is based on TinyUSB that is not officially supported. I’m wondering whether it’s feasible to implement a USB microphone using USBX instead.Regards.

Hello, I’m working with an EVSPIN32G4 demo board and trying to get it running with a Bodine BLDC motor in a sensorless (hall-less) configuration. I’ve got firmware that appears to work initially, but after pressing RESET or cycling the 48 VDC power, I immediately get an “Over Current” fault in Motor Pilot. When I click “Acknowledge Faults” and then press “Start”, the Over Current error comes back right away. I’m still new to this platform, so I’m not sure what’s causing the issue. I’ve attached my Motor Workbench project and the motor datasheet — if someone could take a look and provide some guidance, I’d really appreciate it. Thanks in advance!

Hi,We have a large project that already defines several cmake presets, and we would like to reuse them in VS Code  STM32CubeIDE extensions.RegardsUwe

Hi every one,I want to program STM32H745 nucleo-144 using VS Code, after i generate the code using Cube MX with Toolchain "make file". But when i try to build the code this happen "Something went wrong during the build process: 1".Can any one help me.Thanks.

Hi everyone . I have timer problem again. I use STM32G431KBT6. I'm using timers. timer 3 for pwm pulse direction servo motor and timer 8 for pwm speed control dc motor. But when start timer8 pwm, timer 3 is starting same time. What could be the reason for this? My timers set:   

Post edited by ST moderator to be inline with the community rules for the code sharing. In next time please use </> button to paste your code. Please read this post: How to insert source code. Hey Folks, I am writing firmware on a STM32U5A5ZJ-Q board, I am using FreeRTOS, and am running into some issues with SysTick, originally noticed when HAL_Delay() would just hang. I was also able to verify that uwTick does not change (this may be strange, because SysTick->Val does change as expected). I read in some other forums that  WARNING:When RTOS is used, it is strongly recommended to use a HAL timebase source other than the SysTick. The HAL time base source can be changed from the Pinout tab under SYS.   My understanding is that an RTOS that has SysTick_Handler implemented overrides the __weak handler that exists in the generated code and thereby forces things using SysTick as their timing source to a low priority. Since I already have my code written, so can I just updat

I am using STM32F469I-DISCO interfaced to a custom display operating in DSI-Video Burst mode.I'm using TouchGFX, all compiles ok, however I am getting a HardFault_Handler error relating to TouchGFX::TextProvider as follows. The memory is organised as follows.I think the fault may relate to text object(s) with related wildcards that have been deleted from within TouchGFX designer. I am using TOUCHGFX V4.26.0 but had the same problem with V4.25.0 

Hello,I have been trying to setup Ethernet on a NUCLEO-H563ZI to no avail. As recommended I am using the NETXDUO middleware. When setting up my project with CubeMX I enable DHCP but the MCU never seems to send any DHCP packets (Checking through wireshark). This is with completely unmodified code provided by the NX Core Init which generates the nx_app_thread_entry. After some further debugging it seems like the program hangs while waiting for the DHCP Semaphore which says that an IP Address is ready. Specifically this line:tx_semaphore_get(&DHCPSemaphore, TX_WAIT_FOREVER) != TX_SUCCESS Memory is not an issue in this case as those have been previous issues. I now assign well over 20kb for tx_app and nx_app.This sample program was also tested on a fresh board out of the box. I also have another script that seems to work halfway with messages for DHCPDiscover and DHCPOffer.Bellow is the main code for that program. In this case I don't use the pre-generated nx_app_thread.&nbsp

Hello! I want to implement secure boot / secure firmware install on my STM32u5A9 custom board. I am starting by trying to modify the SBSFU example code from B-U585I-IOT02A example project to run on my board. I followed the instructions in the README to tailor the project for STM32U5A9. I also made the following changes:My debug terminal is connected to UART5 so I modified the com.h file (attached snippet below)I also changed TFM_TAMPER_ENABLE in boot_hal_cfg.h to NO_TAMPER as I was initially having trouble with that engaging during my testing.I uncommented the MCUBOOT_EXT_LOADER in Linker/flash_layout.h as our custom board has an external flash chip but its pinout is different than the standard dev boards and I have not gotten any of my attempts at a custom loader to work. I’m trying to get secure boot working without an external loader first.Running SBSFU_Update.sh (as is from the B-U585I-IOT02A project)  results in successful programming and verification of sbsfu_app_init.b

Can someone please help me find the value of 0R, as I am trying to use the CAN FD, but I am not able to figure out the values of the resistor.

Hi everybody,I've two cards with a STM32F446 on them.My first one works very well, the µc starts a each time.On the second card, the µc starts sometimes (I have a LED on my card that blinks at start).I've checked Vcap (2.2µF), the 3V3 rising (1ms), boot is well connected to GND with a 10k resistor.I cannot see what happens in debug mode, because in debug mode , it starts everytime.Is there a mean to check something else ?I don't understand what happens.If you have some ideas...Thank you. 

Hi Everyone,I am facing an issue with my MCU entering low-power mode.My code works fine when tested separately. I can successfully put the MCU into STOP 0 mode and wake it up through an EXTI line interrupt, but only when the Window Watchdog (WWDG) is disabled.However, when I enable the WWDG, the MCU seems to get stuck at the WFI instruction when trying to enter STOP mode. It doesn’t proceed further or wake up through the EXTI line Interrupt. The only recovery option is a power cycle.Has anyone faced a similar issue, or know what might cause this behaviour when WWDG is active?I am open to sharing the source code.Any suggestions or pointers would be appreciated! 

    Hello ST Community, Our company is preparing to begin a project segment for our mobile application that would involve switching to the ST25TV NFC chip specifically for its anti-cloning protection features. I am not a developer myself, but I would like to gather clarity and guidance as we scope this integration and determine whether the ST25TV chip is the best course forward, given the potential scope of implementation work. We are aiming to: Implement TruST Digital Signature functionality. Enable read/write of URLs on ST25TV NFC tags. Work with the available SDK, noting that it does not currently provide iOS 17 + Swift code. Understand best practices for deployment on iOS mobile devices. Our key inquiries are: Is there existing support for mobile ISO devices that we may have overlooked? What methods are developers using to integrate ST25TV NFC on iOS? What is the scale of work required (effort, complexity, timelines)? Does ST offer any alternative soluti

Hello,Our customer has inquired about the meaning of the last three-digit code in the marking on the L78L15ACUTR.For example, some parts are marked with "8L218" or "8L243" on the top surface.Could you kindly explain what "218" and "243" stands for?Thank you in advance for your support.

I am working on an electronic chessboard that connects to Lichess. The board should be able to detect any chess position at any time, so I cannot rely on move tracking. For this reason, I chose NFC to identify each piece using tags.I am currently developing a cost-optimized and low latency hardware architecture for this project.With the help of @Travis Palmer , I completed my first prototype PCB, which includes 4 antennas and analog multiplexers as described in application note AN6121. Using this approach, I would need 64 antennas, 64 multiplexers and multiple NFC readers for low latency, which is quite costly and complex.Travis suggested an alternative keypad-style antenna matrix layout with 8 row antennas and 8 column antennas (total 16 antennas), as shown below:I understand that with anti-collision it is possible to detect multiple tags on the same row or column. However, I do not understand why the antennas should overlap. Wouldn’t it be better if the antennas do not inte
