Issue SummaryWhen trying to rotate the display on an STM32MP157C board from landscape (800x480) to portrait (480x800) mode, I'm experiencing issues. Using the /sys/class/graphics/fb0/rotate interface doesn't actually rotate the display, and using Qt's EGLFS with rotation settings results in only half the screen being rotated properly.Hardware InformationBoard: STM32MP157CDisplay controller: STM32 LTDC (LCD-TFT Display Controller)Screen dimensions: 800x480 (native landscape)Framebuffer: /dev/fb0DRM device: /dev/dri/card0What I've TriedSetting framebuffer rotation via sysfs: echo 1 > /sys/class/graphics/fb0/rotateThis changes the value but doesn't affect display.Using EGLFS KMS config with rotation:QString configPath = "/tmp/eglfs_kms.json";QFile configFile(configPath);if (configFile.open(QIODevice::WriteOnly | QIODevice::Text)) {configFile.write("{\n"" \"device\": \"/dev/dri/card0\",\n"" \"outputs\": [\n"" {\n"" \"name\": \"DPI-1\",\n"" \"mode\": \"480x800\",\n"" \"transform\": \"rot

Hi everyone, i am using the TSZ121 as a high to low impedance match stage in order to drive a differential MCU (MSP430i20x). The input stage seen below comprises several mosfet optocouplers (see C1-C5) that shape the input attenuation. C1-C5 is simply their cut-off state inherent capacitance. R6 is also the output of a mosfet optocoupler acting as shorted/non-shorted input for ADC offset calibration.The image seen below depicts DC simulation and everything seems as expected.However, on my pcb, i am measuring around 20mV between OUTB & GND and 70mV between OUTA & GND, provided that P1 trimmer is almost exactly centered (adjusted so that center tap is in the middle of adjustment range).The PCB was re-flowed very carefully with a stencil and everything seems near-perfect.R5 & R7 are 0Ω.The pcb was cleaned with an ultrasonic cleaner which as proven after quite a few iterations at work is a very good solution for wiping out leakage between high impedance nodes. Looking at the PC

Hi,I am using Clives loader for the STM32H with the correct pins etc but it never works in the STM IDE, so I thought I would follow controllertechs videos to try and make my own loader, that didn't work either, but I did verify all the QSPI parts reading/wriitng etc are working. I also learned a good test using the CubeMX Programmer (and that fails using my loader for a different reason) but, I then thought OK will test it with Clives and MX Prog, and that fails on verification when I try and load a 1MB test file. I have emailed Clive and he has been incredibly helpful already, but thought I would also ask in the community in case someone has a quick solution?

I have been using STM32N6 to conduct model training and deployment for the model zoo. Now, I want to transfer the generated code to my TouchGFX project for embedded use in the CubeIDE environment. However, when I am transferring several files, before the transfer, the original files did not have this error, but after the transfer, there is this error and it is particularly common, mostly for the official-generated code. As follows:  When these files are transferred： After the transplantation was completed, an error occurred： ./../../Drivers/STM32N6xx_HAL_Driver/Inc/stm32n6xx_hal.h:893:1: error: unknown type name 'HAL_StatusTypeDef'; did you mean 'HAL_TIM_StateTypeDef'?893 | HAL_StatusTypeDef HAL_SYSCFG_GetWriteQosNP1(uint32_t *pQosValue);| ^~~~~~~~~~~~~~~~~| HAL_TIM_StateTypeDef../../../Drivers/STM32N6xx_HAL_Driver/Inc/stm32n6xx_hal.h:895:1: error: unknown type name 'HAL_StatusTypeDef'; did you mean 'HAL_TIM_StateTypeDef'?895 | HAL_StatusTypeDef HAL_SYSCFG_GetReadQo

Hello,I am having some trouble attempting to use the OEMuRoT tools/scripts to sign and encrypt my custom application built with CMake/Ninja. Application was generated using CubeMX and CMake project type was selected. Windows 11, STM32CubeProgrammer v2.19.0, though I am using Git Bash to run the scripts as I notice that e.g. there is a postbuild.sh but no postbuild.bat. I am using the -DK Discovery Kit eval board.I copied C:\Users\myuser\STM32Cube\Repository\STM32Cube_FW_N6_V1.1.1\Projects\STM32N6570-DK\Applications\ROT\OEMuROT_Appli\STM32CubeIDE\postbuild.sh into my application folder.I modified env.sh so that the oemurot_appli_path_project uses a relative path to my application folder: oemurot_boot_path_project=Applications/ROT/OEMuROT_Boot oemurot_appli_path_project=../../../../../../_hmnhwi/customer/my_customer/this_project/workspace/my_applicationThen I modified the postbuild.sh script in my application so that the path to the provisioning directory is correct, with relat

Good day,I have stumbled upon an issue with my device's bootloader that seems to be inconsistent with the ST documentation. I have an STM32G031K8T6. USART1 RX and TX are connected to an RS-232 transceiver, which is then connected to my host PC using a USB-to-RS232 cable:[STM32G03x USART1] <----> [RS232 tranceiver (MAX3232 equivalent)] <---> [FTDI RS-232 USB cable] <---> [Host PC]I would like to use the bootloader to upload firmware to the device, over this UART link. Normally, this works just fine. However, I have observed that the bootloader will not respond if it receives invalid data before receiving the valid 0xF7. To reproduce "good" behavior:Create an empty boardApply BOOT0, and power on (bootloader mode).Connect to the COM port using TeraTerm, or some other serial terminal (57600, 8 bit, even parity, 1 stop bit)Don't send any dataDisconnect from TeraTermAttempt to connect to board using Stm32CubeProgrammer (UART, 57600, 8 bit, even parity, 1 stop bit)Conne

Which is the last version of STM32CUMX and STM32CUDIDE to run on Windows 7 with SP1?Thanks.

Greetings, I am using a Discovery Kit (B-U585I-IOT02A) and I want to use the LPTIM1 to wait 5 seconds (counting x ticks), at the end of the 5 seconds enter in a Callback to do something and then restart the counter again.I want to use as clock source the 32.768Khz crystal (LSE). So, I configured the LSE clock in the RCC section of the .ioc, then I set the LSE as clock source for LPTIM1, and activated the interrupts. At the main function, I used the HAL_LPTIM_TimeOut_Start_IT(&hlptim1, 16383) and used the void HAL_LPTIM_AutoReloadMatchCallback (LPTIM_HandleTypeDef* hlptim) callback to do something. The callback is not being called, I measured the signal at the crystal, and I can't see any clock in it. I guess something's missing in the configuration but I have no clue what it is and I can't make it work. An helping hand would be appreciated.

Hello,For some reason I'm unable to get valid readout of internal MCU temperature. Maybe someone have an ide why this might be happening? System is running on STM32G0B0 MCU. I init ADC over HAL generated code and enable only internal inputs (`ADC_CHANNEL_TEMPSENSOR`, `ADC_CHANNEL_VREFINT` and `ADC_CHANNEL_VBAT`), after init I run ADC calibration which reports that it did it's job. but when I start to read temperature periodically - every minute, I see following results (these are raw values domming from DMA so I assume it is `temp`, `Vref` and `Vbat`):temp Vref Vbat 03B7 07E3 045B 050F 07E4 045D 0513 07E4 0460 0511 07E5 045B 0512 07E5 045B 0512 07E5 045A 0513 07E3 0457 0504 07E9 0481 0509 07E9 0488 0526 07EB 0497 0532 07ED 049C 051F 07EB 0499 0502 07E7 0482 0508 07E8 047B 050A 07E5 0475 0509 07E5 0470 050B 07E5 046F 050F 07E5 0470 050E 07E5 046D 050B 07E3 0467 0510 07E5 0466 0513 07E5 0465 0513 07E5 0466 050F 07E4 0467 0512 07E5 0464 050F 07E5 0463 0511 07E5 0464If I plot these values

We are using the STM32U575RIT6 device and performed a RX/TX swap on LPUART1, ports PC0 and PC1. When we enabled the Swap TX is properly transmitting out of PC0. But we are unable to read anything on the new RX pin PC1. Other than enabling the pin swapping what else would need to be changed? Are there any known issues with the SM32u5 pin swapping? 

 After performing an OTA update, the Bluetooth icon appears as shown in Figure 1, but it does not display the "STM_OTA" name.The correct result should look like Figure 2.I followed the modification steps from this video, including adding the OTA Reboot Characteristic as shown:https://www.youtube.com/watch?v=mRzZOa3jmuM&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=9https://www.youtube.com/watch?v=mRzZOa3jmuM&list=PLnMKNibPkDnG9JRe2fbOOpVpWY7E4WbJ-&index=9The chip I’m using is STM32WB55CGU6, with FUS version v2.0, and ST BLE Toolbox version 1.4.4.The project has been uploaded in the attachment.

Hi,my company is currently evaluating usage of the IIS2DULPX accelerometer in one of the products we are developing. Our use case requires that a wake-up interrupt is generated whenever acceleration sample exceeds a set threshold value. However, we would like to generate this interrupt with a threshold that takes into account either:an absolute value of a data sample, or a difference between a sample and zero-g offset (interrupt generated when sample > threshold - zero-g offset)a difference between a data sample and a configured, constant reference value (interrupt generated when acceleration sample > threshold +/- constant reference value).We would like to do so while keeping the ODR at 400-800 Hz and the ability to configure threshold as a value in a full +/- 16g range. From the data sheet it seems that the wake-up feature is fed by an internal slope filter, making it impossible to use wake-up feature as I have specified above. Therefore, is it possible to either disa

Hello,I'm working on stm32h7 with the STM32CubeIDE IDE and I'd like to know how to make sure that when the debug starts it doesn't delete the whole program. Let me explain: in my flash memory I have data in a specific location and specific size that I've written via the program and that I want to keep.The problem is that when I launch the debug, it deletes the entire flash memory to write the new program.Is it possible not to erase a specific memory location?(I've tried with KEEP and NOLOAD in the linker script but it doesn't work).   thank you

Dear Team, May I know STM32WBA52CG support some basic AI/ML applications. We don't need controllers like STM32N6. If STM32WBA52CG supports some basic AI/ML can you please share some materials,applications notes or some examples where I can see some AI/ML application of STM32WBA52CG. Regards Hari

Hello, Often I need documentation of different components like datasheets.I usually use Google and end up on any datasheet website. In some cases, mainly searching old components, I found datasheets of bad quality, that seems bad photocopies.Has ST any public website where can download it's datasheets? Thanks 

Good Day, Recently I started working with a new MCU (STM32L152). I ported some UART code to handle received data from a different MCU, which worked fine. But as soon as I started testing edge cases I saw some weird things happen. I am using the DMA on the receive, and I rely on the Idle interrupt to send data to a different buffer for processing. It seemed like the Idle interrupt would trigger correctly for the following:- data length < half buffer length - data length = half buffer length - half buffer length < data length < full buffer length -  full buffer length < data length  But it does not trigger for: - data length = full buffer lengthIt turns out in HAL_UART_IRQHandler (in stm32l1xx_hal_uart.c) there is a missing piece of code that enables this to happen. This code existed in the previous MCU's UART driver. I checked that I had the newest library downloaded for STM32L152. The piece of missing code is attached. /* * NOTE: This else was manually put

Hi,I am implementing RS-485 communication on the STM32G491. Based on available references, I’m currently using a custom GPIO pin for the DE (Driver Enable) signal, since the default USART1_DE pin is already allocated for another function. In the RS-485 initialization API, there are three parameters: DE polarity, assertion time, and de-assertion time. Do these parameters have any effect when a regular GPIO is used instead of the hardware-controlled DE pin?I am using the below configuration for init.huart1.Instance = USART1; huart1.Init.BaudRate = 115200; huart1.Init.WordLength = UART_WORDLENGTH_8B; huart1.Init.StopBits = UART_STOPBITS_1; huart1.Init.Parity = UART_PARITY_NONE; huart1.Init.Mode = UART_MODE_TX_RX; huart1.Init.HwFlowCtl = UART_HWCONTROL_NONE; huart1.Init.OverSampling = UART_OVERSAMPLING_16; huart1.Init.OneBitSampling = UART_ONE_BIT_SAMPLE_DISABLE; huart1.Init.ClockPrescaler = UART_PRESCALER_DIV1; huart1.AdvancedInit.AdvFeatureInit = UART_ADVFEATURE_MSBFIRST_INIT; huart1.Adv
