STM32 MCUs

Hi community.TLV230adc5140 - SAI 4CH(TDM) - STM32 - USB_FS_ 4CHmic - Window(LInux RP5) I reuse partly code from memsmic1 project to create 4 microfone audio device. Everything look well for channel 1 and 2 I got some trouble whit CH3 and CH4.  Please help whit    wrong channel mapping for channel 3 and 4. It is mapped on channel  1 and 2  on usb interface. One can see it on attached picture. Here is TLV switched off, SAI(DMA call back) reused for 4 sin generator 1,2,3,4 kHz for every supposed channel. Here you see the picture.Where i  am wrong?    

Hello I've been trying to recreate the DCMIPP_SnapshotDecimation example with STM32CubeIDE, I have been running into several issues. I have solved most of them, I am encountering a memory error while debugging my code. I was able to flash and debug the original example successfully on the STM32N6570-DK. However, when I try to read a value from the AXISRAM address (0x34200000), it fails: (address does not exist and unable to reconnect to target device). AXISRAM3 which it should be the address 0x3420000 is activated and initialized in the main. Initialization of  the signal processor and starting the DCMIPP pipeline was passed without any problem:if( ISP_Init(&hcamera_isp, &hdcmipp, 0, &appliHelpers, ISP_IQParamCacheInit[0] ) != ISP_OK ) { Error_Handler(); } if( HAL_DCMIPP_CSI_PIPE_Start(&hdcmipp, DCMIPP_PIPE1, DCMIPP_VIRTUAL_CHANNEL0, BUFFER_ADDRESS, DCMIPP_MODE_CONTINUOUS ) != HAL_OK ) { Error_Handler(); }But, trying to access the buffer addr

Hi everyone, I am working on a dual-core project using the STM32H747XI. I am implementing a custom Tickless Idle mode in FreeRTOS on the Cortex-M7 (CM7) core using LPTIM1 as the wakeup source. I’m facing a specific issue regarding the interaction between D1 and D2 domains: The Scenario: CM4 is running a continuous task (intended to stay active). CM7 enters low-power mode via vPortSuppressTicksAndSleep. If I use HAL_PWR_EnterSLEEPMode(), everything works perfectly—CM4 keeps running, and CM7 wakes up as expected. If I switch to HAL_PWREx_EnterSTOPMode(PWR_MAINREGULATOR_ON, PWR_STOPENTRY_WFI, PWR_D1_DOMAIN), the CM4 core seems to "die" or freeze as soon as CM7 enters the DStop state. Is it physically possible for CM4 to continue executing code if the D1 domain is in DStop (CM4 is using only LPTIM1 on D3 and timers on D2)? Code snippet used on CM7: _weak void vPortSuppressTicksAndSleep(TickType_t xExpectedIdleTime) { // Generated when configUSE_TICKLESS_IDLE == 2. // Functio

I noticed that STM32CubeMX2 (DEBUG features page) offers only three debug modes: JTAG 4‑pin, JTAG 5‑pin, and Single Wire Trace Asynchronous.In many practical cases, developers use only the SWCLK and SWDIO lines to save pins, so the absence of a simple Serial Wire option (without Trace) seems to be a limitation of the current STM32CubeMX2 release.This option is still available in STM32CubeMX1 when working with similar MCUs, such as the STM32H5 series.Is this understanding correct?

How to configure the sysTick_Handler(), when we are setting the HCLK 386MHz in CubeMX and systemClock() is generated, but while configuring sysTick(), uint32_t SystemCoreClock = 64000000; already there in system_stm32h7xx_dualcore_boot_cm7_cm4.c(void)SysTick_Config((SystemCoreClock) / 10000);Will it effect mine overall MCU speed and performance, because after all I'm using FMC NAND Flash to communicate with the external Micron Flash, because there I need to calculate the clock cycles need to the write enable (WE), Setup time, Address Latch Enable (ALE) time etc, will be effected, or it is completely independent, should I only consider FMC_CLK which is coming from PLL clock source 2.

Dear sir / madam The UltraLibrarian WBA5M (Module) footprint is flawed. Potentially it can screw the module under reflow.Those center GND pads are not placed correct. I noticed when comparing the ST dev-board module. see image..

Hi all,I noticed that when using the encoder, the motor undergoes an alignment phase during which it completes a rotation until it reaches the position where the Index Z signal is triggered.I was wondering if it's possible to skip this alignment phase by adding the Hall sensors (like with the B-G473E combined with the STEVAL-LVLP01 board), and if so, what should I specify in the Workbench or in the Code?Regards,Jules

I bought STM32F4DISCOVERY. But in the STMcube IDE, i see only STM32F407G-DISC1 board.  Are STM32F4DISCOVERY vs STM32F407G-DISC1 same? Can I select STM32F407G-DISC1 and create a project in the IDE and use STM32F4DISCOVERY hardware to run the project? Will it create any issues?

Split from STM32CubeIDE missing “STM32 Project” and CubeMX after fresh installation - that issue was resolved.This is a new issue.The new version 2.1.1 appears pretty useless even after trying to make a project with the separate cubemx. From the IDE you cannot then build the project. It just sits there. I would hope that the IDE is at at capable of building and compiling the project but it appears that is no longer the case.Did you employ someone from microsoft to break it. It was working perfectly before hand. New->STM Project->.....->build->debug. I will revert back to 1.19 to avoid wasting more time and just use an older CubeMX as that was the only reason I upgraded Please leave working software alone or simply improve it and not break it for no reason

I am currently working on an STM32 TrustZone project and trying to implement the following flow:NonSecure world running↓Calls Secure_add()↓Secure world executes↓Returns value 8↓UART prints the result in NonSecure worldHowever, I am facing an issue while jumping from the NonSecure world to the Secure world. The expected secure function execution is not happening properly.If anyone has faced a similar issue or has suggestions regarding NSC gateway configuration, linker settings, or TrustZone function calls, please share your insights.  this much i am getting the outCMSE_NS_ENTRY uint32_t Secure_add(uint32_t a, uint32_t b){return a + b;}    ------------------------ My Nsc.c entry logic  for(int i = 0; i < 5; i++){printf("NONSECURE WORLD RUNNING\r\n");printf("I am amritha\r\n"); //for(volatile int d=0; d<500000; d++);}uint32_t result;printf("Before Secure_add\r\n");result = Secure_add(5,3);printf("Before Secure_add\r\n");printf("Secure result = %lu\r\n",

Hi,  I'm using a STM32F072's DAC to output a SIN and a COS wave. The problem is I can only output values up to approx. VDDA / 2. The DAC drives unity gain amplifiers to drive a 50 Ohm load. The DAC is connected directly to the amps, using the buffer does not help. VDDA = 3.3 V. Here, CH4 is connected directly to the DAC output via a 10:1 probe. The black things on the scope inputs are 50 Ohm termination, so the CH2 and CH3 signals having only half the amplitude of CH4 is expected. All channels are DC coupled. I'm writing to the DAC using the DHR12L1/2 registers (using the STM32Cube HAL): uint16_t value = (uint16_t) (ltbDacSinLut(ltb_dac_ch1_counter_) ^ 0x8000) & 0xFFF0; HAL_DAC_SetValue(&hdac, DAC_CHANNEL_1, DAC_ALIGN_12B_L, (uint32_t)value);where ltbDacSinLut returns values in the range of [-32768, 32767].  Dividing the value by 2 before writing to the DAC results in undistorted SIN / COS output, but of course the output swing

Hello,Can anyone tell me how to measure pulse width with the HRTIM? I need to measure a very short pulse from my time domain reflectometer. I am thinking of using the NUCLEO-H753ZI board with the STM32H753ZI MCU. All I know about measuring pulses with the HRTIM is that I need to use the external event registers and that the minimum pulse width must be >2.5 ns. Any help would be greatly appreciated.

Hello everyone!I am trying to get a custom board based on an STM32WBA5MMG to join my existing ZigBee network. As a first test, I have created a basic project in CubeMX, that configures STM32_WPAN to generate a ZigBee project with one OnOff-Endpoint and sets up USART2 for logging. When I generate a CMake-based project and try to compile it in VSCode with the STM32 extensions installed (without making any changes to what CubeMX generated), I get a bunch of linking errors and the build fails:[build] /Users/dg/Library/Application Support/stm32cube/bundles/gnu-tools-for-stm32/14.3.1+st.2/bin/../lib/gcc/arm-none-eabi/14.3.1/../../../../arm-none-eabi/bin/ld: warning: /Users/dg/Library/Application Support/stm32cube/bundles/gnu-tools-for-stm32/14.3.1+st.2/bin/../lib/gcc/arm-none-eabi/14.3.1/thumb/v8-m.main+fp/hard/crtn.o: missing .note.GNU-stack section implies executable stack [build] /Users/dg/Library/Application Support/stm32cube/bundles/gnu-tools-for-stm32/14.3.1+st.2/bin/../lib/gcc/arm-non

Hello,I am having some hard time to connect my nucleo-wl55jc1 to any LNS, even though i checked that Device, Join, and App EUIs are all correct and there is no mismatch, but whichever LNS I try, I always get the same result First, I tried with an indoor RAK gateway, these gateways use MAC version 1.0.3, and the nucleo example uses version 1.0.4 Then I tried using MeteoScientific LNS and Helium network, could not join as well. Finally I tried to connect LORIOT to my RAK gateway, and they successfully connected, but still the nucleo could not join the server, and the gateway did not transfer any packets. Even though the steps are fairly simple, I don't know what is the problem here     what is the meaning of "Event received: RESET" in the nucleo serial logs?

I am trying to download the windows version of the IDE but I can't get it to work. Either the download button doesn't do anything or it's just not there. I've tried with different email accounts, different web browsers, different networks but that didn't do it. I've looked on here and it was suggested to disable browser extensions like ad-blockers and such and I've disabled all of them and still nothing. I would appreciate any help.

Hello STM32 Community,I am stuck in a critical situation with my STM32H533RE custom board and need help recovering it. I have exhausted all methods I know.- Hardware Setup:    - MCU: STM32H533RE (custom PCB, not Nucleo)    - ST-LINK: External ST-LINK V2 (Firmware V2J46S7)    - BOOT0: carry out the cia test point    - USB: DP/DM routed to test points (wires soldered for access)    - SWD: SWCLK , SWDIO , NRST (Pin 2) connected to programming header- TrustZone Configuration    - Configured Secure and Non-Secure world using STM32CubeMX    - Secure peripherals: SPI1, SPI3, UART4, ICache, DCache    - Flash watermarks configured for secure/non-secure regions- What Happened (Step by Step)    1. Device was originally in **Open state (0xED)** — everything worked fine    2. I could connect via SWD in Normal mode and read all memory including secure regions    3. I attempted to transition

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 recognize my STM32 as a gaming device. I thought this part would be easier; the Blackpil

Hello People, I’m trying to make tracing on a Board containing either a STM32H743 or a STM32H747 work and it drives me crazy. I need to debug a custom build board from our company, where I have a uVision Project for it and a circuit board, but no Cube-Project. It is important to debug UI with timestamps, so that we can measure how long the UI takes. First of all, I tried to debug it with Ozone. I downloaded the tracing example for the STM32H743 Eval Board and tried tracing on the Eval Board, which worked. So I planned to do tracing on our own hardware on a very minimalistic Project to check to make it work. I than generated a very minimalistic Cube-Project to count a value and to trace it and generated a uVison-Project from it. I somehow made it work to trace it in Ozone, as far as I remember correctly I used the pex-File for it. But unfortunately, I don’t know what I did wrong, the tracing does not capture any data any longer.   I also tried the same with

Where can I download the STM32H503 Nucleo schematic?

In STM32CubeMX, here is the orientation for a chip with a red dot marking pin 1 at the top left when text reads from left to right.In real life, here is the orientation for a chip with a red dot marking pin 1. As far as I'm aware, all STM32 chips are oriented like this, with pin 1 at the bottom left when text reads from left to right. Why is the text rotated 90 degrees differently? Is this intentional? If there is a reasonable explanation, I'm interested in hearing it. It seems to only add confusion. Wouldn't it make more sense if the default orientation (or at least the text orientation) to match between the two? In STM32CubeMX, you can rotate the part for convenience. This is useful. However, the text also rotates, so if you put pin 1 in the bottom left like in reality, the text is now rotated. (This is the same story in STM32CubeMX2.) 

We need further clarification regarding the difference between the above ICs.We recently purchased the mentioned STM32 MCU, but received two different variants. In one IC, the ST logo on the right side has the marking “e3” with “L” outside the circle. In the other IC, the ST logo on the right side has the marking “e4” with “L” outside the circle.Kindly clarify the difference between the “e3” and “e4” markings and confirm whether both ICs are equivalent in specification and performance.

I am developing a device that implements the USB device class.According to application note AN4879 "Introduction to USB Hardware and PCB Design Considerations Using STM32 Microcontrollers" it is written as follows:Based on the USB specification, a USB device must use VBUS sensing detection. When the device detects the host presence, it connects its pull-up resistor to either a D+ or D- data signal. This allows the host to detect the device presence on the bus. There are two cases: • The USB device is bus-powered. VBUS sensing is not mandatory (USB is always connected when the device is powered)• The device is self-powered. VBUS sensing is mandatory. Pin PA9, a five volt-tolerant pin, which includes an additional function natively dedicated to VBUS sensing. I have an option when the device is self-powered. Therefore, VBUS sensing is mandatory.It is also written that the user must avoid the situation when the MCU is not powered, and a 5 V VBUS is connected to PA9.The absolute maximu

Hi,I am trying to migrate a STM32F767ZGT6 based project to STM32H743ZGT6. According to AN4936, they should be pin to pin compatible. When I manually compared the each pin, and assigned the state of each PIN as used in STM32F767ZGT6 to STM32H743ZGT6, they seem indeed to be P2P compatible too. But If I try to list PIN compatible MCUs in STM32CubeMx, as of the latest v6.17.0, STM32H743ZGT6 is not listed. Please see the screenshot below:Am I missing something? Or this is a bug in CubeMX? I just don't want to throw 100s of $ down the sink. I attached my IOC file to see if anyone can reproduce my problem.Thanks.

Hello everyone. I have recently made my own STM32 board based on the STM32F405. After soldering all the components and testing all pads and connections, finding them to be wired correctly and checking that the 3.3V is being supplied to all the correct pins, I tried to upload some code but to my shock the STM32F405 isn't establishing a connection via the ST-Link V2 nor the USB cable. After trying multiple fixes, I suspect the issue might be the STM32F405 chip that I got off AliExpress itself.  So before I took any further steps to replace it, I decided to post my schematics on here for review in case the problem was in my PCB design. If you have any remarks on what might have caused this problem, please share them. NOTE: The -B label is referring to ground, and P is the VCC. schematics:
