Hello,I am currently working with the STM32MP157-DK2 platform and would like to integrate OpenPLC into my Yocto-based Linux distribution.I would like to inquire whether STMicroelectronics provides any existing Yocto layer or recipe for OpenPLC. If no official support is available, I would appreciate guidance on the recommended approach to create a custom Yocto recipe for integrating OpenPLC into the build system.Specifically, I am looking for best practices regarding:Creating a custom layer for OpenPLCWriting a BitBake recipe for OpenPLC (including dependencies and build steps)Integrating OpenPLC runtime with the STM32MP1 ecosystemAny potential compatibility considerations with the STM32MP157-DK2Any references, documentation, or examples would be highly helpful.

Hello, What HAL2 API can I use to turn on/off the output of a timer? In HAL (ver 1) this could have been done like this:TIMx->CCER &= ~TIM_CCER_CC1E; // Example for Channel 1: ~TIM_CCER_CC1E // or __HAL_TIM_MOE_DISABLE(&htimx); Thank you,-Gil

I’ve been seeing a lot of people in Whittier struggling with unexpected lock issues lately, especially with house doors and car keys getting stuck or breaking at the worst possible time.One thing I’ve noticed is that most people only start looking for help when it’s already an emergency situation, and at that point they end up calling the first available service without checking if they are properly licensed or experienced.Has anyone else experienced delays or overcharging from unverified locksmith services in the area?I was also trying to understand how important it really is to always choose a lisenced lockmith in whittier instead of just going with whoever is available quickly. Some people say it doesn’t matter as long as the job gets done, but others strongly disagree because of security risks.Would be great to hear your experiences or recommendations on how you usually handle emergency lock situations.

I am making use of the SWV to plot a 5Hz Sine Wave.The output on the plotter does not resemble a sine wave:Any recommendations to fix this?

There does not seem to be any way of viewing a debug variable in hex.The closest workaround is to prefix (void*) before the expression in the watch window. This is no good for viewing an array of hex digits like for example a CAN bus message.

Hello.I am trying to implement RFID using NXP's NT3H2211W0FT1. The microcontroller I am using is the STM32C031F6.After powering on the board, the first thing I do is read the data from the NT3H2211W0FT1 via I2C, but sometimes I can read it and sometimes I can't.I tried leaving a wait of more than one second after powering it on, but that didn't change the situation.The program for the I2C part is below.while(icdata_flg==0){ HAL_GPIO_WritePin(GPIOA, ANNTENA_SW_Pin,GPIO_PIN_SET); HAL_Delay(10); tdata[0]=0x01;//Read HAL_I2C_Master_Transmit(&hi2c1,0xaa,tdata,1,100); HAL_Delay(10); HAL_I2C_Master_Receive(&hi2c1,0xab,rdata,8,100); HAL_Delay(10); HAL_GPIO_WritePin(GPIOA, ANNTENA_SW_Pin,GPIO_PIN_RESET); } I would appreciate any advice you could give me regarding I2C communication.

Hi there, I found several issues in the STM32CubeMP2 CMSIS headers as follows:1. Missing opening parenthesis in bitmask macrosIn stm32mp21*xx.h, _Msk macro definitions were missing the opening parenthesis, leaving a dangling closing parenthesis with no matching open:// Before #define USB_OTG_GCCFG_FSVMINUS_Msk 0x1UL << USB_OTG_GCCFG_FSVMINUS_Pos) // After #define USB_OTG_GCCFG_FSVMINUS_Msk (0x1UL << USB_OTG_GCCFG_FSVMINUS_Pos)While the C preprocessor performs simple text substitution and the shift operation may still evaluate correctly at the call site depending on context, the unbalanced parentheses break static analyzers, automated code-generation tools, and linters that parse these headers. Adding the opening parenthesis also makes operator precedence explicit and unambiguous.2. Malformed comment delimitersAll of header files involves inline comments used *!< instead of the correct /*!< Doxygen-style comment opener, missing the l

Hi,I took reference  for calulating the timing / cycles for my MT29F1280AJAAA (I'm using STM32H745ZIT3) In Asynchronous mode - 5, which is saying ~50Mhz in the datasheet. But I'm running FMC at 131MHz clcok, what ever the calculation I have calculated are as per this knowledge notes, https://community.st.com/t5/stm32-mcus/how-to-configure-the-fmc-peripheral-to-interface-an-stm32-mcu/ta-p/705805So help me debug the issue using CRO hardware or Software timing calculation, What I'm observing is that in middle some pages data integrity is failing, after writing page 25m sec delay I'm reading back. its failing what ever the content I have written on to that page.Running FMC at 131MHz, and sysTick HCLK = 396MHzMy calculations, I also tried changing values by incrementing then, last or first byte is coming 0xFFTCLRSETUPTIME = 3TARSETUPTIME = 3STEUPTIME = 2WAITSETUOTIME = 3HOLDSETUPTIME = 2HIZSETUPTIME = 4Question : Is Common space timing and Attribute space timing should be same&nbs

The "S2-LP bring-up good practices v1.0.pdf" [1] document states the following information regarding AFC:"AFC_CORR is 2-complement byte (signed). Granularity is 508Hz for 50MHz Xtal"The mentioned step size of 508 Hz for a 50 MHz oscillator also corresponds to my practical observations.The following information can be found in the datasheet:[..]Fdig/(3*(2^13)) where Fdig is the frequency of the digital block (24, 25 o 26 MHz).1 LSB is:At 24 MHz: 976.5625 HzAt 25 MHz: 1017.25260416 HzAt 26 MHz: 1057.9427083 Hz[..]Since Fdig corresponds to 25MHz for a 50MHz oscillator, the AFC_CORR step size would therefore be 1017Hz.This doesn't match the actual results or the information in the mentioned PDF.What is the correct formula to calculate the step size for all oscillator frequencies?Thanks~Matthias[1] https://community.st.com/t5/interface-and-connectivity-ics/frequently-asked-questions-on-st-s2-lp-sub-1ghz-transceiver/m-p/736882/thread-id/11431?attachment-id=28318 

Hi, I'm relatively new to STM32 series and so far have experience with STM32F103 only. My current goal is to learn and work on master-slave system, with master being an embedded linux (IMX6ULL), and the slaves are (supposingly) STM32 boards. Cameras modules and some sensors will be connected to STM32 boards. The STM32 will proess the camera stream and sensor readings locally, and send the processed/estimated results to the IMX6ULL. Some prior serach and local technical support recommend me STM32F104 series, which some sources suggest its image processing capacities are limited. I'm a bit lost in the sea of choosing appropraite hardware setup, and would like to hear some further comments on hardware choice. By far my conditions on board choice are the following: (1) Has DCMI camera interface (2) Hardware has sufficiently capacity to process VGA image stream around 5-10 fps. (3) Can execute STM32 image processing library (https://github.com/STMicroelectronics/stm32-mw-ipl) There may be f

I designed my own PCB based on the EVSTSPIN32G4 evaluation board and created a project in STM32Cube IDE. When testing the STSPIN32G4’s internal driver, I encountered an issue: no matter what I do, the GHS voltage remains at 5.8V, the GLS voltage is 0V, and the OUT voltage is also 5.8V. I have tried setting PE8 to high or ground, as well as using PWM, but the voltage on GHS1 never rises. Reading the I²C register values does not trigger any protection; the STBY value is 0 and does not enter low-power mode; the nFAULT pin remains low regardless. As far as I can tell, there are no errors. Could an expert please provide some guidance?

I upgraded to STM32CubeIDE Version: 2.1.1 and imported my existing projects as STM32. I opened Project / Properties / C/C++ Build and it says "This is not a CDT project." I've never seen that before using version 1.18.1. What happened and how can I fix it?

Hello Everyone,I am attempting to debug code on the STM32 Blue Pill board. The project compiles successfully, but when I start a debug session, it fails with the message “Launch debugging failed,” along with additional error details shown below. I would appreciate any guidance on resolving this issue.Note: I am using an ST-Link V2 programmer (A2020 version).Wiring is done correctly checked multiple time.I had doubts about the Debugger configurations. Are there any other settings must be modifiable, or any other ways arethere?" Error in final launch sequence:Failed to start GDB serverFailed to start GDB serverError in initializing ST-LINK device.Reason: (18) Could not verify ST device! Abort connection."

Hello my friends, I hope you are doing great.I am trying to create a custom driver for UART peripheral with CMSIS register header files.I have created a build system using the board files and linkers and make. So far I have been able to make drivers for the GPIO pins.Now I am trying to create my own driver for the UART peripheral via the CMSIS. So far I have created this: int uart_params_init(uart_t *uart){ if (!uart) return -1; // defualt configs: uart->tx_pin = 9; uart->rx_pin = 10; uart->baudrate = 115200; uart->tx_port = GPIOA; uart->rx_port = GPIOA; uart->instance = USART1; uart->tx_af = 1; uart->rx_af = 1; return 0; } int uart_init(uart_t *uart) { if (!uart || !uart->tx_port || !uart->rx_port) return -1; if (uart_initialized) return 0; // Enable GPIO clocks for the port: if (uart->tx_port == GPIOA || uart->rx_port == GPIOA){ RCC->IOPENR |= RCC_IOPENR_GPIOAEN; } else if (uart->tx_port == GPIOB || uart->rx_po

Post edited by a ST moderator. Please use English in this community. Please read How to write your question to maximize your chances to find a solution   手册上写着在高分辨率模式下功耗 90 µA，在低功耗模式下功耗低于 1 µA。可是我用示波器串联电阻抓出来的功耗接近1MA，并且未使用MCU配置传感器时功耗就已经接近这个值了。传感器通过开发板的3.3V接口进行供电。电路图如下所示，哪里存在问题呢？ Translation: The manual states that the power consumption is 90 µA in high-resolution mode and less than 1 µA in low-power mode. However, the power consumption I measured with an oscilloscope using a series resistor is close to 1 mA, and this value is already close to the power consumption even without configuring the sensor using the MCU. The sensor is powered through the development board's 3.3V interface. The circuit diagram is shown below. Where is the problem?

I am experiencing an issue in STM32CubeMX where all peripheral Configuration panels stay empty, while the Mode panels and System Core → Parameters render correctly.What I have already tried:Starting CubeMX standalone (not via CubeIDE)Creating a completely new empty projectDeleting the .stm32cubemx folderDeleting and rebuilding the entire STM32Cube\RepositoryReinstalling CubeMXForcing JavaFX software rendering (-Dprism.order=sw)Setting Windows display scaling to 100%Enabling/disabling GPU accelerationVerifying that the bundled JRE is complete (java.exe + jvm.dll present)In all cases, every peripheral Configuration section remains empty, while Mode sections work normally.It appears that the JavaFX UI for peripheral configuration does not initialize, but without any error message.Has anyone seen this before, or is there a way to force or debug the JavaFX UI subsystem in CubeMX?Thank you in advance.Kind regards, Cornelis Dekker (Netherlands)

I am working with the STM32H723ZG and trying to implement Ethernet communication without using an RTOS using LWIP(TCP/IP)  Setup Details: Board: NUCLEO-H723ZG IDE: STM32CubeIDE v1.19.0 Ethernet stack: LwIP PHY interface: RMII Flashing tool: ST-LINK (onboard) Test performed: Ping test from PC Observed behavior: The Ethernet port LEDs (orange and green) remain solid ON after connecting the Ethernet cable. Ping is failing continuously, I got (Destination host unreachable) error. Troubleshoot taken: Checked with multiple Ethernet cables to ensure cable isn't a problem.  I'm using static Ip and checked the Ip is correct in lwip.c while flashing the board. Rebuilt and reflashed the project multiple times. After all this still I can't ping the board. Assistance required : is there is any problem in cache coherency in the code? Kindly check with the MPU unit configuration and let me know is there is any issue?   I'm

Hi,I have a question regarding STiRoT provisioning on the STM32H573.As I understand, during the Secure Boot provisioning process, the public key hash is injected into the OBKeys area of the device to establish the root of trust. However, I would like to clarify where the original public key itself is stored and how it is handled during runtime verification.Based on our current design, we are planning the following approach:The firmware image is signed using our own external HSM, not STM32HSM.The corresponding public key hash is provisioned into the device OBKeys during manufacturing.At boot time, STiRoT checks that the public key contained in the firmware image matches the provisioned public key hash, and then uses that public key to verify the firmware signature.From this perspective, our understanding is that the device does not store the full public key in its internal non-volatile memory (e.g., OBKeys or other secure areas), but instead relies on the provisioned public key hash in
