LSE clock is set in the Cube and initialisedAfter intitialisation the following registers are not set correctly and the LSE clock isn't calledRCC->BDCR->LSEDRIVE not set to hight event though macro calledRCC->BDCR->LSCOSEL set to LSIRCC->BDCR->LSCOEN not setThis looks to be a bug in the HAL library

I've gone over the hardware with a multimeter and all the pins have the right continuity, I've checked the design against the Nucleo-144 L552ZET6Q schematic and it checks out so far, and I've also checked the connections to the ST-LINK/V3 pins I'm using. I haven't been able to program the MCU once yet via SWD or USB (I'm mostly sticking with SWD for now).If anyone has any suggestions or thoughts, I'd appreciate any help I can get. If any additional information is needed from me, I'll do my best to provide

Would like your help just to conifrm.Due to difficulties in sourcing will this crystal work with STM32H750 ( HSE crystal ).FA-128 25.0000MF20X-K0 Epson.Thank you for your help!

Hi All,Background: during my very first experiments with the STM32 Motor Control SDK 5.Y.2 I did hear something like a two tone alarm coming from the motor when a critical overcurrent or overload situation occured. I was pretty sure at that time, there there must be some routine that uses the motor as a speaker to emit such a beep when required.Topic: With my current project it would be quite handy to be able to output a short beep in some situations without having to assemble dedicated speaker or beeper. But I could not find a piece of code in the MCSDK-Lib that is related to such a function.Question: My question is now, whether the alarm I did hear with the older MCSDK was just an artifact of the motor control. Or was this an intended functionality and got removed during the code cleanup in 5.Y.4?Has anyone used a motor as speaker with the MCSDK already? In my opinion that should be possible since a motor and a speaker are not very different.Regards Thomas

"Short" calibration of the coil and conversion to "Z: Reflection"Can anyone tell me what is being said there a bit more clearly, please? I'm familiar with the open/short/50ohm calibration procedure of the VNA and some aspects of Smith charts. But that line stumps me.

Hi!In my project I added a text area with one wildcard. I checked option "Use wildcard buffer", but left "Initial value" blank. Then in setupScreen() function I wrote some text to the wildcard buffer using Unicode::strncpy(). After starting my project in simulator to my surprise the text showed up with spaces displayed as fallback characters (?). I added some characters to the wildcard characters space was there too. I tried everything and in the end I set the initial value of the text area for some text with space in it. Then the wildcard text was rendered correctly with spaces. Am I doing something wrong or is it some sort of bug? Regards,Piotr

Hi,Anyone know how to export data from SPC5Studio Terminal to Excel?

Hello. I'm Using L9369 for H-bridge control.I'm trying to set GIO0~8 pin high(Button interface), but i can't(Analog Output - SPI control)i'm using SPI command, and i saw L9369's manual and i follow the instruction below steps to set GIOx pin as high.Set "SPI_GIOx_MuxCtrl" as "1111" , so i send command and get response. 0xB901FFF7 for register 114d -> 0x0e41ffe8 0xB981FFE2 for register 115d -> 0x0e61ffe8 0xBA81FFF3 for register 117d -> 0x0ea1ffe5 2.Set "SPI_off_GIOx" as "0", so i send command 0xC38000F5 for register 135d -> 0x -> 10e000ec 3.Set "SPI_GIOx_HSctrl" bit as "1", so i send command 0xBB81B0E0 for register 119d -> 0x0ee000d2i check each GIOx's status via SPI comannd and get response 0x44000001 for register 136d -> 0x0x11000015is there anything else i need to do? or check? what should i do? please help me.thank you.

I have tried to add a library with .a extension but all tries had been unsuccessfully.I have added the search path to "Library Search Path (L)" section in MCU GCC Linker.I have added the library name to "Libraries (-l)" section in MCU GCC Linker.With this when building the project, I get the next error:tools\arm-none-eabi\bin\ld.exe: cannot find -lMyLibraryIs there any other step I'm missing?Hope you can help me with this.Regards

HelloI am familiar with STM32. I have a simple project with CubeMXOne ADC reads 3 channels, continuousmade disable , DMA active.I turn everything on and start the first ADC conversion with a function HAL_ADC_Start_DMA.My questionsHow do I start another ADC conversion?What should I test to make the program wait for the ADC conversion to complete and the data transfer via DMA?Thanks you

I am making a DFU for stm32f4-discovery board.My DFU is using a project generated by STM32CubeMX V1.0. And It worked well with the program generated by the STM32CubeMX V1.0But when I worked with a project generated by STM32CubeIDE, I cannot make the main program run.I had made these steps:First, in system_stm32f4xx.c#define USER_VECT_TAB_ADDRESS   #if defined(USER_VECT_TAB_ADDRESS) /*!< Uncomment the following line if you need to relocate your vector Table in Sram else user remap will be done in Flash. */ /* #define VECT_TAB_SRAM */ #if defined(VECT_TAB_SRAM) #define VECT_TAB_BASE_ADDRESS SRAM_BASE /*!< Vector Table base address field. This value must be a multiple of 0x200. */ #define VECT_TAB_OFFSET 0x00000000U /*!< Vector Table base offset field. This value must be a multiple of 0x200. */ #else #define VECT_TAB_BASE_ADDRESS FLASH_BASE /*!< Vector Table base address field.

Hi team! I am working on the OLED interfacing with STM32F103C8T6. All I want to do that is to display the counter value from 0 to 255 on OLED. But when I simply put the random number such as 48 it shows its equivalent ASCII value not a decimal value as it is 48.What is the reason of it?I am delighted to ST community for the help.Thanks in advance.

Section 6.4.4 of RM0433 is the only place I could find that says what to do with VBAT rail when not using a battery. It says the following:If no external battery is used in the application, it is recommended to connect VBAT externally to VDD through a 100 nF external ceramic capacitor.Does it actually mean "through"? That wording implies this: ...but I don't see how that make sense.Does anyone else read it differently?

Thanks

Hi all I have a new board of STM32MP157C, But I found the eMMC's pin in board is not the default pin. If I want to boot from eMMC what I should do? write the otp to set pin of eMMC and set the device tree. is that enough ?

Hello,is there a method to read/ write NOR flash on QSPI

We have the STM32L4R-Eval kit revision 01 as well as revision 02We want to use STM32L4R9AI in our prototype, which was used in the above Eval.The difference between these two versions looks like in revision01 U5 SRAM is populated but not working correctly; in revision02 it wasn't populated. Please Confirm.We want to use STM32L4R9AI in our prototype, which was used in the above Eval and our prototype is not ready yet, So, we want to start our development using eval-kit and our product requires 800x480 resolution TFT LCD on RGB interface.This is the list of challenges we are facing as per below:1) As per our display resolution required frame buffer size for double buffering is around 2MB that can not be fit into internal RAM(640KB). So want to use external SRAM.Now, we have two options:2) Option1: Use external SRAM connected to OCTO SPI2 SRAM(U5 IC) but it was not originally populated because of some limitations as per its datasheet.-> Is this limitation specific to the Eval kit only

Hello,I build an application with FatFs Middleware to log data on a uSD card.I used the same protocol on FatFs_uSD application with wl55 mcu.f_mkfs and f_mount function return FR_OK.but f_open return FR_NO_FILESYSTEM i tried to change between SDHC and SDSCi passed the SD module power supply from 3.3V to 5Vi changed min heap and stack sizesi changed _MAX_SS in ffconh.h... but always the same problem !any suggestion please ?

Hello,I'm trying to communicate to ST NFC IC ST25r3914 with another mcu through SPI communication. I have successfully initialised NFC IC but I am getting NFC IRQ interrupt only four times. After this control comes only till RFAL_NFC_STATE.

I only can find the packages for the L4 and L5.

HelloI need to build an automatic programming and testing tool for industry.Do someone can help me finding a programming tool to flash simultaneously, up to 10 STM32 MCU ?The binary file is the same for all of them.I need to integrate the software programming tool through a supplied API for C/C++ (like for STM32CubeProgrammer, I saw it seems exist).So I'm looging both for hardware and software solution.THank you in advance for your ideas.Regards.

As shown in the picture, when I send the generate command, a compilation error occurs. The problem appears to be that std=c99 needs to be adjusted. Does anyone know how to fix this please?Thanks in advance.
