Hi, its my first postLet me introduce myself, my name is Manuel, I am from Spain (English is not my native language) and I have joined the forum looking for help. My profile is that of a maker with very little programming experience (an AI maker). AI helped me a lot to make the programs I’m migrating a project from Arduino to an STM32 Blackpill; I managed to get it working on Arduino.Sim racing pedalsThe pedals are a potentiometer (for the accelerator) and a loaded cell (for the brake). Well, what I thought would be the hardest thing to do—getting the STM32 Blackpill to “read” those sensors—I’ve managed to do. I press buttons on the console and see the changes… but what was easy on Arduino—turning it into a game display for Windows—I’m not being able to do on the STM32… the libraries that Gemini recommends are either missing or don’t work… I’m looking for help getting Windows to recogniz

Hello All,We are developing 2 MCU (STM32U5 and STM32N6) based solution which has a Wi-Fi module. There is a need that should allow either STM32U5 or STM32N6 to communicate with ST67W611M1A6BTR Wi-Fi module at any given time. The FW is under our control, and we know that at any given time only one MCU will interact with Wi-Fi module. Do I need to use a multiplexer to decide which MCU to communicate or is it possible with the help of FW. Please suggest what needs to be done on schematic and FW. Regards,Sakshi 

the STM32L431 can trigger per 0.102S by WDI,  but WDO always have a reset signal, why ?   

Hi，Recently, I have been evaluating the DAC accuracy of STM32H743. The data sheet mentions the SNR and ENOB , but I have no idea how to test it. Could you please provide a testing method or a testing plan? Looking forward to your reply.

Hi everyone,I’m bringing up USART2 on an STM32 using bare-metal Rust (#![no_std]), direct register access (no HAL, no CubeMX).The CODE looks correctlyHowever, the data itself is wrong.Instead of transmitting 'A' (0x41), the terminal consistently receives values like:0xCE0x05(always stable, but never 0x41).#![no_std]#![no_main]use core::ptr::{read_volatile, write_volatile};use core::panic::PanicInfo;use cortex_m_rt::entry;#[panic_handler]fn panic(_: &PanicInfo) -> ! {loop {}}#[inline(always)]fn r(addr: u32) -> u32 {unsafe { read_volatile(addr as *const u32) }}#[inline(always)]fn w(addr: u32, val: u32) {unsafe { write_volatile(addr as *mut u32, val) }}/* ================= BASE ================= */co

Im using STM32SD library on my stm32f407vet6 board.  I want to make a logging system for my application. My initial logic is: on setup we count number of files in our root directory and create a new file named dataLog{fileNumber}. Then we write data into that file and check if its not empty. In given code example im always getting only last write into file (fouth write). As ive got this library only works in FILE_WRITE or FILE_READ modes. I trtied to use FA_OPEN_APPEND modifier but when im using this im getting errors while file creating.And another thing is that im always getting a lot of initialization errors and file open errors overall while using this library, maybe it depends on me using stm32f407vet6, any advices would be great. Now i will try to use an advice from github issue of "unstable work with sdcard on stm32f4" - i'll try to redefine the value of the SD_CLK_DIV to bigger value.  &n

Good morning,  I need to send data using UART to a board with a specific delay between single elements, which I obtain as I'm using LABVIEW, but on the board said specific delay is not obtained, and worst of all the delay between datas is not constant. I figured there would have been some additional delay, but is there a way to decrease it or at least make it constant? or is it intrinsic to the UART technology?  Thx all

i am try to interface tft lcd via LTDC using FMC, i checked that ram is working fine and test also passed , but i try to resolve lcd issue but it not resoled yes. Can someone help how to do that. i am uploading the complete project which is created. Please help how can i interface with lcd. 

Hello All, I'm working on a board, wherein i am using DRAM 256Mb 200MHz with Mfr. No: part no   APS256XXN-OBR-BG (as recommended in STM32N65 DK) but while going through it i found that this part no is not recommended for the new design. Can anyone please share the alternative of this part no or guide in this.       Best Regards, Sakshi

Hello everyone,I’m looking for any Wi-Fi connectivity implementation examples for the STEVAL-STWINBX1 (STM32U5). Ideally, I’m searching for a solution that integrates with the eLooM framework, or at least a reference on how to properly add Wi-Fi tasks within eLooM.Specifically, I’m trying to find:Wi-Fi driver/task examples compatible with STWINBX1Any eLooM-based implementation of Wi-Fi or network communicationExample projects that connect to AWS IoT using Wi-Fi (HTTP)Documentation or sample code showing recommended methods for enabling Wi-Fi cloud communication on STWINBX1So far, I haven’t found a clear reference project for

 Hi.I'm having an issue with the error: failed to erase memory on STM32F407.I'm using the board https://github.com/mcauser/BLACK_F407VEand the debugger https://github.com/WeActStudio/WeActStudio.MiniDebugger.and the original STM32F407VET6 chip.Yesterday there was no issue, but today when I tried to continue my project, the problem appeared. I have set the SWD frequency from Auto to 100 kHz. At some point, it worked with BT0 = 0 and BT1 = 0 after several attempts of pressing the reset button before starting the debug. I have replaced the debugger twice and tried it on the same chip type on a different board, and it worked. However, it did not work on the chip on my project board. I tried it with the STM32Programmer, an

HI allI'd like to know how to be able to read a data file from windows.I have to convert those data (binary) from windows system, to another format, and then write them to a flash W25Q.The only part I'm missing is how to open then read those bin files in windows. I have around 100 of those windows files to work on, and they are on the same windows folder.So what are my options to do that.Thanks all.For now I'm using a Nucleo-L432KC, on STMcube 1.19.0.

Suppose I have a project where I have to  continuously  read and display values from the adc called  AD9215BRUZ, I have NUCLEO-H753ZI  board , is it possible?  Can the STM Hseries  read and sample parellel data , if yes then how should I proceed , if no then what are the limitations.Thank you 

We used a DAC with a sample-and-hold circuit on one of our custom boards. The RC filter was not mounted; instead, the DAC output was directly connected to an SMA connector. We enabled the DAC in the firmware, and after testing, we observed a large amount of current flowing through the STM32 board. Upon inspection, we found a short between the 3.3V rail and ground on the STM32 board.   Please find the attachment for your reference.

Hello everyone,I am interfacing ADXL345 in stm32f103c8t6 by using I2C connection. I have fixed the set up on a board. I would like to know if I can identify the movement of adxl by observing the changes in x, y, and z values if there is no vibration but the board is moving smoothly, that is, to the right or left. If not, how can I predict when the adxl will go forward or backward without relying on the sensor's tilt or vibration? I just want to create a basic activity detector where the logic would be :1. If the setup does not move, the output should be zero.2. If the setup is vibrating and moving, the output should be one.3. If it is simply vibrating (and not moving in space), the output should be 0.So, basically, I want to detect actual mov

Hi Sir,From the schematics of steval-usbc2dp, the AUX channel is connected to both STM32 MCU and display unit(sink).Does it mean, STM32 MCU can access DPCD information between Host terminal(source) and display unit(sink), or transmit DPCD to display unit instead of Host terminal?Thanks,Eric Fu    

Hi Everyone, I wanted to add a audio codec with stm32U585aii6Q can anyone share he reference or guide how can it be done. Thanks Regards Sakshi

(MCU running, requires power cycle) I am trying to configure an 8080 16-bit parallel LCD using FMC on an STM32H5563 development board, but it is inconsistent and unstable.

Can we interface the Raspberry Pi camera with the STM32 that has a camera interface feature? 

Hello,While rapidly powering the MCU on and off to simulate the vehicle’s internal power conditions, I have observed that the MCU occasionally ends up in this error state.Has anyone experienced a similar issue or can provide insight into what might be causing this behavior and how it can be resolved?
