Solved

First of all, I am not using CUBE IDE, this is a bare metal.Second: STM32H523. ADC (continuous mode; DMA). ADC is configured on PA0 (i.e. INP1, single-ended), GPIO configuration is analog mode.On the pin I can probe (oscilloscope) my signal (correct amplitude): a sinus. But the data (from DMA) is noise.Configured with PA1, all works fine (so my soft is ok). Using ADC1 or ADC2 does not change anything.Second observation: with PA0, the DC is not fixed (floating pin), but configured on PA1, the pin is DC-driven (about VDDA/2, high impedance).=> For these reasons, I have the feeling PA0 is not connected to ADC. I can't find anything in registers/documentation/erratas explaining this (on H7 there is some analog switches, but nothing for H5).Any clue? Thanks! 

In the RM0456, the LPUART has a block diagram (67.4.1) with a register called LPUART_ RTOR but there is no documentation about this register. For USART, this register is related to Receiver timeout interrupt but this feature is not available for LPUART.

I am using the STM32L433RCT6 and need to assign a GPIO pin as an external interrupt, which will be used to wake and shutdown the MCU (shutdown must use minimal power).However, I am not sure if I have to use a specific GPIO pin, or if I can use any GPIO pin for the external interrupt ?The external interrput will be connected to a momentary push button (net PWR_SWITCH)...There will be a procedure to wake and shutdown the MCU as explained below (there is also a link to a video to demonstrate the procedure)... Start the switch-on cycle by clicking the button once. After approx. one second, an LED will flash. You mustacknowledge the LED light immediately by clicking the button again. This sequence - a click as soon as the LED appears - will be repeated two more times. After a total of four clicks, the MCU will wake up.If you do not act promptly after seeing the LED light, or if you push the button too soon, it will ignore the switch-on attempt.  This four-click switch-on cycl

I was checking maximum frequencies of some MCUs and noticed i can pick ADC frequency in CubeMX clock configuration up to 80MHz for TSSOP-20 STM32G030. Its maximum frequency is 64MHz.Datasheet states it can deliver maximum 2Msps on 12 bit but with its 1.5 Sampling and 12.5 conversion cycles it reaches way higher sample rates.I checked some of the reference manual chapters and did not noticed anything unusual, prescalers seems to accept /1 divisions as well.I am not familiar with reference manuals. Datasheet 5.3.17 also shows 35MHz maximum frequency. What's the thing i am missing? Is it a bug on interface?

The MCU of NUCLEO-U031R8 is LQFP64. But if I import the example of NUCLEO-U031R8, STM32CubeMX shows it as UFBGA64. 

Hi Everyone,I noticed that CubeMX (version 6.14.0) generates a call to HAL_OSPI_DLYB_SetConfig in octospi.c even though I have configured the OctoSPI to bypass the delay block.Is it safe to just remove any Delay Block related code?Is this a bug in CubeMX? It increases the code size, so I would like it to be removed if it's not necessaryMy target is a Nucleo-U5A5. Thanks!Timon Zijnge 

On the STM32H7B3I-DK, several STMod+ signals share two GPIO options (e.g., PA11/PA0, PC3/PD5 for SPI2/USART2). Even when I configure only one of the shared pins as a simple GPIO (e.g., output or input with pull-up), it doesn’t function — no toggling, no input reading, and no internal pull-up.I've:Disabled conflicting peripherals (USB, SPI2, USART2, etc.)Verified GPIO clocks and init codeTried minimal code to toggle pinsConfirmed it’s not a code or hardware mistake on my sideIs there something board-specific or internal (e.g., STMod+ mux, hidden peripheral lock) that blocks these pins?Thanks,

Dear,We would on the STM32H7B0RBTx connecting 2 external QSPI RAM of APS6404L-3SQN-SN.Therefore we will use the 2 QSPI RAM chips in Multiplex mode, but we have only 1 NCS pin that we can configure.When we look in the application note AN5050 on page 27 we see that it is possible but with STM32Cube it isn't possible to configure the NCS pin on port 2.What we doing wrong here?How we should configure the other parameters of the QCTOSPI in STM32cube for the used RAM chip?OCTOSPI1OCTOSPI2:

Hi,We are working on a design using the ST33TPHF2XI2C TPM, and we noticed that the chip provides four GPIOs. However, there is a lack of clarity regarding their configuration and control.Clearer documentation is needed on how the GPIOs are linked to specific NV storage indices and how they can be configured or controlled through them.Is there any documentation or example showing this mapping? Additionally, could you please provide a schematic or reference design (e.g., evaluation board) and any further documentation related to the ST33TPHF2XI2C that might help?Thank you in advance for your support.

Hello everyone,I am currently working on a project with a STM32U545. There was a first prototype electronics + software that was working. I made a new hardware and I wanted to use the same code with just a few modification.For this, I just copied the STM32CubeIDE project, modified the configurator with the integrated CubeMX, regenerated the code and compiled.This is where I ran into problems:I have this compilation error:../Drivers/STM32U5xx_HAL_Driver/Inc/stm32u5xx_hal_uart_ex.h:231:36: error: unknown type name 'UART_HandleTypeDef'; did you mean 'RTC_HandleTypeDef'? 231 | HAL_StatusTypeDef HAL_RS485Ex_Init(UART_HandleTypeDef *huart, uint32_t Polarity, uint32_t AssertionTime, | ^~~~~~~~~~~~~~~~~~ | RTC_HandleTypeDefSTM32Cube IDE version:  1.18.0STM32CubeMX version: 6.14.0When looking at the generated driver (file stm32u5xx_hal_uart.h), I noticed that the UART_HandleTypeDef was missing its name before the semicolon:typedef struct __UART_HandleTypeDef { USART_TypeDef *Insta

Hello,We are currently in the testing phase with the EVSPIN32G4 board using the various available software suites.After upgrading to the following latest versions:MC Workbench 6.3.2 → 6.4.0STM32CubeMX 6.??.? → 6.15.0STM32CubeG4 Firmware Package V1.6.0 → V1.6.1I created a project in MC Workbench for the EVSPIN32G4 board and generated the project for CubeMX.To my surprise, the microcontroller is no longer the correct one in CubeMX, even though it worked fine with the previous version.The evaluation board uses a 64-pin package, but the automatic configurator now selects a 100-pin package instead.I tried rolling back the software versions, but nothing seems to work: the package remains stuck on 100 pins.Do you have any idea what could be causing this issue?Thank you in advance.

Hi, Since there's a huge market for microcontrollers on boards such as the Arduino, like the ATMega and ATTiny, which are available in 20- or 40-pin DIPs, I was wondering if ST competes (could be with the 32bit or 8bit line) with those somehow. If so, what are the options of microcontrollers that compare with them?I'm asking because sometimes using an STM32 is overkill for certain projects, while some STM8 options are too restrictive. Having the flexibility for adding those TH components makes everything much easier when designing boards that do not necessarily need the complexity of manufacturing in SMD. Best,Alessandro

What are the best practices for controlling the exposure time of the VD55G1 in Linux?

I am working on STM32 Trusted Package Creator. I read the artical How to deploy SSP using a step-by-step approach at section "3.1.2.2. Secret file content for STM32MP2 series". I need to create a secret file that contain FIP-EDMK OTP as the image below:Could you please explain on Enc/Wrap box.When should I select No Encryption?When should I select Wrapping?When should I select Encryption? For the FIP-EDMK What should I select? 

I am using NucleoH563ZI board with threadx and netxduo.I have the following code, it makes http requests.The first completes ok, but the other 2 has a problem where the dns returns with 0xA3, basically can't resolve the host url. With wireshark i noticed that the url somehow contains one additional character: "firestore.googleapis.comD" and with the second case: "firestore.googleapis.comH"calloc (or malloc, does not matter which i am using) returns a valid and good pointer then strcpy copies the url string.In debug I can see that the url is copied succesfully. But after the next calloc suddenly an excess character appears at the end of the string, thus the dns fails to resolve.It does not matter what I put between the strcpy and the calloc, it always fails the same way.if I compile the program with only a single request, then it sometimes works. Any idea what is going on? //get public IP char* public_ip_str = calloc(30, 1); if(public_ip_str == NULL) { Error_Handler();}

Hello，I want to use the PB6 pin as an external interrupt input. When the PB6 pin is triggered, the program enters the low-power stop mode from the normal operation mode. When it is triggered again, the program enters the normal operation mode from the low-power stop mode. According to the above, the test found that after the program enters the low-power mode, it cannot return to the normal operation mode again. Does anyone have experience in this area and can provide me with a solution?

I added a folder called Docs to my project, then created release notes using Word and dropped in the newly created Docs folder. When I try to build, I get a message box:How do I fix this?

I have read some posts about this topic already but unclear if this works or not. I used the STMCubeMX to create a project using FreeRTOS and USB Device CDC (USB-Serial) together and some LED GPIO's.I can only get one or the other to work, but never at the same time. I have tried adjusting the memory settings heap/stack as suggested in some of the forums but that didn't help. Just wanted to check if anyone has this working or if I should switch to a different scheduler/OS? I am using a STM32F303RE; any help would be appreciated. Thank you

Hi @Peter BENSCH  I have the same problem and I have sent 2 emails already. I received the automated email to my first request like others, BUT it has the following warning: "Attention: Sender not authenticated". Is there something i need to do? I have used the same email as my st account, company (Continental) email. I am afraid my email may block the response. We really need Teseo Pro to install new firmware on LIV4F EVB. Could you help me to check my activation request? Thank you very much.

Hi there,I'm curious how other folks handle this situation:Presently, I have a number of screens that all complete some hardware process (ex. move motors) and then navigate back to the Home screen. I'm introducing some additional logic that, across all such screens, would add a conditional to determine what next screen to display (ex. Critical Battery screen if battery is low, ... , with the Home screen being the 'else' option should none of the other conditions be satisfied).I don't want to duplicate and maintain this logic across all of the screens - where is a good place to put this? Thanks,Julia

I was using STM Cube IDE version 1.17.0, and I am not getting the option to choose the Stm32Cube in Target Project type by default it is selecting the option of empty. I have been using the same version for few months and I have never faced this issue.. Could you find a solution for this.

Hai. Currently we are working in a project, for that we require AEC Q-100 Products. In that we need STM32F405VGT6 in Automotive Grade. AEC Q-100

This is driving me crazy, whay timers on STM32 are so complicated and no normal information / datasheets etc, how to use.Timer2 is working (external clock), Timer interrupt (TIM_IT_UPDATE) also working, but not capture interrupt. And signal is also present on capture pin, when I manually write capturing code without timer inside main() thread, then it's working. And if I check premade HAL code, there is no timer starting function to enable capture interrupt, just only update interrupt.So my initial code:static void MX_TIM2_Init(void) { /* USER CODE BEGIN TIM2_Init 0 */ /* USER CODE END TIM2_Init 0 */ TIM_ClockConfigTypeDef sClockSourceConfig = {0}; TIM_MasterConfigTypeDef sMasterConfig = {0}; TIM_IC_InitTypeDef sConfigIC = {0}; /* USER CODE BEGIN TIM2_Init 1 */ /* USER CODE END TIM2_Init 1 */ htim2.Instance = TIM2; htim2.Init.Prescaler = 0; htim2.Init.CounterMode = TIM_COUNTERMODE_UP; htim2.Init.Period = 4294967295; htim2.Init.ClockDivision = TIM_CLOCKDIVISION_DIV1; h

I'm trying to program the EVSPIN32G06Q1S3 to run a PMSM, but I attempted to use STM32CubeMX to help with the pinouts and code. The problem is that I can't find the EVSPIN32G06Q1S3 in the board selector. Is there a way to download then import the board information to STM32CubeMX? If there's not, could I get documentation to help implement the board through the MCU selector? Thank you!

Hi All,I am successfully programming and debugging a NUCLEO-STM32F401RE by its embedded ST-LINK programmer using STM32CubeIDE v.1.12.0 on a computer running Ubuntu 22.04.3 LTS, updated and upgraded.I have a second PC running exactly the same Ubuntu, CubeIDE, CubeProgrammer versions but when I try to debug the same NUCLEO board I get the error message "No-ST-LINK detected! etc etc".I deduce that my USB cable is just fine, that no hardware issues are present and that my two PCs looks the same but some set up difference(s) should exist between them preventing the interface to run properly on the second machine. I wasn't able to identify this difference and solve the problem.I am aware that several "No ST-LINK detected" posts are present on the STM32 Forums but none of them fixed the issue.Finally, I upgraded STM32CubeIde and Programmer to a third computer (same Ubuntu version) to their latest release, while keeping the other two PCs "identical", and can confirm that the upgrade did NOT fi
