Hi ST Community / @Peter BENSCH I use my solar panel connected to the STEVAL-ISV020V1 to charge my LiPo battery. Everything works fine and it charges the battery. However since I am trying to charge it indoors, during night-time, my solar panel doesn't reach the min required voltage of 2.6 to operate the STEVAL-ISV020V1. Now I am wondering if the STEVAL-ISV020V1 becomes a load instead of being a charge controller when this happens because it drains the battery with a very low voltage at a certain time. 

Hi!I have generated an n-Class Classification static library with NanoEdge AI Studio using data from ISM330ISN. I want to use this library in the ISPU template project that comes with X-CUBE-ISPU (X-CUBE-ISPU\1.1.0\Ispu\ism330is_lsm6dso16is\template\ispu). I have pasted the .h files (NanoEdgeAI.h and knowledge.h) and the static library (libneai.a) in the ispu_utils folder and have linked the static library by going to Properties > C/C++ Build > Settings > Tool Settings > GNU STRED Cross C Linker > Libraries and inserting the following information:But after hitting "Apply", "Rebuild Index" and "Apply and Close", when I try to build the project, I get the following errors:  07:30:02 **** Incremental Build of configuration release for project ispu_basic **** make all Building target: ispu_basic.elf Invoking: GNU STRED Cross C Linker reisc-gcc -mcpu=reiscl -mfp32-format=ieee -Os -ffunction-sections -fdata-sections -Wall -Wextra -Wdouble-promotion -fno-strict-al

Hello Forum, I am struggling with a sync timer problem and I have no more idea for resolve it. Here we go :TMR5 is configured as master for TMR3TMR3 is configured as master for TMR4 I configured TMR3 as OnePulse output signal with a delai from a OutputCompareStatus of TMR5I configured TMR4 as PWM signal started by OutputCompareStatus of TMR3 I do Init/Configure/Start after a powerOn and the system works well. I want to do an update of the delai on TMR3 and, impossible to have a correct synchronization between my signals as in the first call.I did several attempt and I lost my self in all theses, someone know the exact sequence of call I have to do for make the magic happened ?Thanks a lot When it works, Any other attempt stop/update same delai/start, the blue wave loose the synchro   Mickael

Hi,we are using the LSM6DSO in Fifo mode and with the double tap feature. Our firmware configures the Sensor Frontend to give an interrupt at fifo_th on INT1 and for double_tap on INT2. Therefore, we explicitly disabled the INT2_on_INT1 bit inside the CTRL4_C register.But still we see the the INT2 interrupts on the INT1 line. (See plot)We always reset the sensor to default. So I guess it seems something is not correctly configured.Here is the code for configuring the sensor:  // configure for the first time ret_code_t err; // Get ID err = lsm6dso_device_id_get(whoamI); if (whoamI[0] != LSM6DSO_ID){ APP_ERROR_CHECK(NRF_ERROR_NOT_SUPPORTED); } // Do reset uint8_t res; err = lsm6dso_reset_set(PROPERTY_ENABLE); do { lsm6dso_reset_get(&res); } while (res); // Disable INT2_on_INT1 to avoid wrong Interrupts lsm6dso_ctrl4_c_t ctrl4_c = {0}; ctrl4_c.i2c_disable = PROPERTY_ENABLE; ctrl4_c.int2_on_int1 = PROPERTY_DISABLE; writeReg(LSM6DSO_CTRL4_C, (uint8_t *)&ct

Hi,I am currently designing a PCB with bluenrg332AC and need the layout / Gerber file to make progress. But I couldn't find any on the Internet, so can anyone provide me with the file or give me some hint of finding the file? Thank you!

I developed with the stm32f756 chip and then switched to the stm32h743 chip.Then, the functions "LL_SPI_TX_FIFO_FULL", "LL_SPI_IsActiveFlag_BSY", "LL_SPI_IsActiveFlag_TXE", and "LL_SPI_IsActiveFlag_RXNE" that were in "stm32f7xx_ll_spi.h" cannot be found in "stm32h7xx_ll_spi.h". What is the reason and which function should I use to use those functions in stm32h?Please share your knowledge. Thank you.

Hello,Does StellarLink support SPC560P microcontrollers?Best regards.

I have followed this STM wiki tutorial about basic PD Sink. Everything is running according to it, but I am unable to see voltage and current measurement inside UCPD monitor. I have also followed the set-up of debugging button which is working correctly and prints the voltage inside trace. But the measurement graph is unfortunately blank. Where might be the problem?github: link 

Hi folks,I use CubeMx to generate UART∕DMA code for STM32L4xx MCU.CubeMx uses currently latest STM32Cube_FW_L4_V1.18.0 package, but HAL_UARTEx_GetRxEventType() is not included in it, neither HAL_UART_RXEVENT_* events.I found it is included in the latest STM32L4 git. Could I somehow use latest STM32L4 git to generate a code by CubeMx with required fix automatically or would it always require manual work to replace HAL_Driver files? Cheers

Hi folks,I'm using HAL_UARTEx_ReceiveToIdle_DMA() on STM32L4. If I use minicom and type a few characters, HAL obviously detects an idle state after each single character I typed.I'd like to configure a idle timeout value used in HAL_UARTEx_ReceiveToIdle_DMA(), so it would suite my use case.Could someone point me to the right place such a fix? Cheers  

I am wondering if HAL functions have some builtin protection mechanism or if I have to wrap them around a  semaphore/mutex take/give. For example, if two tasks call `HAL_ADC_Start(&hadc1);` or `HAL_UART_Receive_IT`, what will happen? Shall I use a semaphore/mutex at OS level?  

A usual approach is to branch from a given project by making a copy of it and develop further on the copy, leaving the original intact. How can this be achieved in the STM32CubeIDE project tree?I tried it by copying the directory in the filsystem, to a different directory, edited every file containing the original project name to the new one. Even edited the .metadata and every occurence of the original name in the new directory tree. It lead to an existing new entry in the tree view Could be that I even did an Import by browsing to that new directory.But the result was that I was said it not being a CDT project when I wanted to open the properties on the new project icon.What is a safe way to do achieve this?   

Hi,I copied below code from internet which works perfect while using HAL_UART_Transmit. However, I want to understand more why there is minus 1 (-1) at timeout parameter ?P.S.: This question may not be directed at the right section, apologies for that. Please feel free to direct me on the right section. Thanks.

In stm32f1xx_ll_gpio.h, LL_GPIO_AF_EnableRemap_SWJ(), LL_GPIO_AF_Remap_SWJ_NONJTRST, LL_GPIO_AF_Remap_SWJ_NOJTAG(), LL_GPIO_AF_DisableRemap_SWJ() all use SET_BIT(AFIO->MAPR, AFIO_MAPR_SWJ_CFG_xxxxx);which is incorrect, as SET_BIT is #define SET_BIT(REG, BIT) ((REG) |= (BIT))and the read value of AFIO_MAPR.SWJ_CFG field according to RM0008 is unpredictable.JW

Hello friends, i design  ac/dc converter circuit using VIPER-319HD with eDesignSuite. One point makes me confused. In attached document, i am not sure these points are GND or not. When i look the datasheet, it seems that these points are related with GND but i am not sure about that. Can you clarify my doubts? Thanks all for your efforts.

I am encountering an error while attempting to create any project in STM32CubeIDE, which states, 'Code generation could not be done because the necessary firmware package is missing. Not able to complete STM32Cube project creation.' I am using the most up to date software version (1.14.1) and all my packages are up to date as well.I have attempted several troubleshooting steps, including:Downloading and installing the package using 'Manage Embedded Software Packages.'Manually downloading and unzipping the package.Replacing the downloaded F4 package with a patch file, as suggested in various forums.Changing the repository folder location.None of these solutions have resolved the issue for me. The only workaround I have found is to create the project in the default workspace, which was initially created in 'C:\Users\xxxx\STM32CubeIDE\workspace_1.14.1.' I also made sure that my other project workspace folder has the same administration access as my default workspace. And nothing worked fo

Hello.I encountered strange CubeIDE behavior on a customer board with an STM32G0B1CEU.I've found similar glitches on this forum, but they mostly stemmed from fake HW.I use all original STM from MOUSER.If I enable PWM on TIM4 in MXcube, without NVIC, I generate the code, then using CubeIDE and stlink-v3e I upload the code to the MCU without problems, it works without problems, the oscilloscope shows what it has.But as soon as I activate anything with NVIC (TIM PWM Interrupt, DMA interrupt, ...), I generate the code in CubeIDE, then when uploading the code to the MCU it terminates with an MI error message, see attachment.Where is the problem?Please help.

Hi,I am trying to replicate this example by ST to understand DMA but I come up with below issue when I click on Add. Could you please help me resolve it ?  

Hi all,I have a STM32F746 disco board and I'm trying to understand what the visual configurator (VC) does and doesn't do. I created an blank demo project for the board and I answer yes to the "initialize the board to default..." (or something like that).There is only one function created by the VC: MX_GPIO_Init(). I can see all the code inside it that initializes various pins. The I2C3 pins (SDA and SCL) are there too. The VC does *not* have the I2C3 enabled.Then, I enabled the I2C3 in the VC and saved. Now the code for the pins for the I2C3 is no longer inside MX_GPIO_Init(). In fact, is nowhere to be found ... by me... but the I2C3 works fine.Where is the code to initialize the pins for the I2C3 when I enable I2C3 in VC?BTW I'm calling the VC the window that opens up in STM32CubeIDE when you click on the ".ioc" file. Thanks.

Hi everyone,According to AN486, It's possible to connect a "RGB666 display panel" to a MCU with RGB888 LTDC peripheral. (Uploaded Picture).Now, Is it passible to connect a "RGB888 display panel" to a MCU which equipped by LTDC565 peripheral? How is connections?Regards 

Hello,related to the post https://community.st.com/t5/stm32-mcus-touchgfx-and-gui/using-cpp-exceptions-in-touchgfx-application/m-p/267439 is C++ handle exception included in TouchGFX release ?I did not manage with the code here below, testing a string for a float with std::stof. (TouchGFX 4.21.4)Thanks

I have built a sine wave to square wave circuit and now want to measure its frequency with the STM. I can see on the oscilloscope that the circuit works, however I can detect neither a rising nor a falling edge with the chip. It is not a problem with the code as I can detect both when they are generated by the chip with PWM or externally with a generator (which is old and its square wave really isn't that square) but also they are much slower.The frequency of the wave is 1.24MHz, measured with the oscilloscope. I don't think that this is too fast, the timer runs at 96Mhz, but maybe using interrupts at this speed is too much?The minimum voltage of the wave is 0.6V. I am suspecting that might be too high to be considered a logical 0 but I can't find documentation.I would appreciate any input and also if you could point me to documentation that would be nice!

Hi @Imen.D ,Please help me with a way to enable clocks to RAM_D2 and RAM_D3 section via STM32CubeMX.I am assuming somehow by default the clocks to RAM_D1 is enabled in code,I do not find a call to RCC->AHB2ENR which is enabled (i.e., not commented out) in the code generated using STM32CubeMX.My team mates are asking me not to modify code (like enabling macro DATA_IN_D2_SRAM or adding assembly code in Reset_Handler section) and rather use some setting with the STM32CubeMX to enable the clocks to RAM_D1, RAM_D2 and RAM_D3 sections.Please share your inputs.Thanks!Rajeev

Hi,MCU- STM32H7I get a busfault exception when I read bank2 flash memory. I can read bank1 with no issues. From the flash register SR2, it shows as ECC double bit error. This is new pcb and I can flash the hexfile to bank1 successfully. Even a Jlink memory read showed read error (below SS):I erased the entire chip using "JFlashLite.exe" and after that it started working normally. Why is this so ? Are we supposed to erase the entire flash for every new MCUs ? Regards,Andy
