Solved

Hello, I tried to run the RTC DS1307 first using libraries available on the internet. It was not successful. Later I tried to run the communication "manually" but it doesn't work either. Please help. The module with DS1307 works on Arduino. Through the Arduino I have set the output from the SQW Pin to flash every 1 Hz. Using STM I try to disable this function by typingHAL_I2C_Mem_Write(&hi2c1, 0x68<<1, 0x07, 1, 0x00, 1, 1000);but nothing happens. Please help me because I can't stand it anymore.To sum up:1 . I set configuration:2 . Generate the code via Cube.3 . Add one line of code: /* USER CODE BEGIN 2 */ HAL_I2C_Mem_Write(&hi2c1, 0x68<<1, 0x07, 1, 0x00, 1, 1000); /* USER CODE END 2 */and LED connected to SQW output of DS1307 is still blinking after uplode code to STM32F0 Discovery. What I do wrong?SincerelyPaweł

Hi, I created my own model and saved it as .h5.However, when I analysed I got the error below. E010(InvalidModelError): Couldn't load Keras model D:\motion.h5,E010(InvalidModelError): Model saved with Keras 2.9.0 but <= 2.6.0 is supportedDo you have any ideas on how I could handle this situation?Thanks,

I have q question about TS393 comparator.Datasheet says : Wide single supply range 2.7 V to 16 V or dual supplies (±1.35 V to ±8 V)I dont understand dual supplies condition.What does mean "dual supplies (±1.35 V to ±8 V)"?

Hi,   I'm using SPC58EC Disp board. I want to use ultrasonic sensors with it. For that I have to config eMIOS as input capture mode. So, is there any example to config the libraries. If any kindly give it with some instructions. Thank You

ContextI am working on NUCLEO-U575ZI-Q with an external ADC wired to the board. The ADC generated a rising edge on one of its pins, "DRDY" each time a sample is available.My objective is to retrieve the ADC sample without involving the CPU. The current solution is a DMA triggered by DRDY sending X dummy bytes to SPI TX register (X is the size of one sample from the ADC). The SPI then send (and read) 3 bytes to/from the ADC, receiving the sample. The bytes received are read with another DMA, but that is not the subject of this topic.In a normal case, the DMA gets triggered (ADC says "data are ready"), 3 bytes are sent so 1 sample is read, then another sample is ready, etc.. All is fine.In a case where the DMA is blocked for whatever reason, it will be triggered once (hit and fire, referring to figure 64 or RM0456 Rev 3, page 663), then a second trigger will occur (hit and memorize), and finally a third trigger will occur (hit and trash), generating a "trigger overrun event".

there are two difference i found : 1). there is no Additional RAM.. 2). no 2nd checker core in SPC58NG84E7QEH0Y. CAN ST team provide more details what is mean by additional RAM here.. Many ThanksShambhu

I'm trying to upgrade the FUS and wireless stack version on my STM32WB55 Nucleo board via ST-LINK using STM32CUBE Programmer GUI tool and seeing this error message FUS_STATE_IMG_NOT_AUTHENTIC. I'm using "STM32WB5x\stm32wb5x_FUS_fw.bin" to upgrade the FUS version. Any suggestions to resolve this issue?

I am using the STM32WB55 microcontroller where I use BLE and integrate my main program with code that I am implementing.On the other hand, I need to use LoRaWAN and for this I use the HOPERF RFM95 module in which only the radio part is integrated but in which I could integrate the MAC layer in the STM32WB55 to be able to use LoRaWAN. Is it possible to integrate the MAC layer code inside my STM32WB55 or is it better to use a LoRaWAN module like the CMWX1ZZABZ and control it by AT commands?Regards,

I have an ADC chip, CS5532, that sets the MISO line on PB14 Hi if data not available, and Lo if it is. Can I read the state of the MISO line?Every time I try to do it I read that the pin is Hi (I am reading the IDR register)

Hello, I recently moved to the new 5.Y.4 version of the SDK because I am using a custom PCB based on STSPIN32G4 with external OPAMP resistor network (external gain) and after hours of searching I found out that 5.Y.3 doesnt support OPAMP in standalone mode due to a bug which has apparently been fixed in 5.Y.4, but now that I moved to the new version and do the workbench project new from scratch and building the code, I get the error "ST Intranet updater server unknown" (I get this even with standard settings) and in CubeIDE there are also errors when building the project which are not linked to any certain .c or .h file, the error occurs in the linker block as it appears.any help is greatly appreciated.

What is this value that is written to the USART_BRR register?What is it for?I don’t understand why the calculation is done using the formula: fclock / (the divisor, in my formula it is 5 * baudrate)For example, here is an example calculation:I made the numbers much smaller to simplify the example.fclock / (divisor, in my formula it is 5*baudrate)fclock ==Clock frequency==30 Hertz.Desired baudrate==2Divisor == 530 fclock / 2 baud * 5 divisor==3 this number is written to the USART_BRR register.3 what is this number?What is it for?BRR== Baud Rate Register. But 3 is not the baudrate I needed. I have 2 desired baudrate.Or does it not matter what my desired data rate is?Why would I then enter the desired baud rate if that's the case?Does this formula calculate the speed that will be applied, and not the speed that I need?-----------------------------------Maybe this will be useful: Shown in the pictureIf a marker is set every 3 bits at a clock frequency of 30 Hertz, based on these markers, w

Hi,I'm trying to find the .hex demonstration file for the STM32F429 Discovery Kit. I searched the STM32F429 Discovery page which directed me to the STM32CubeF4 MCU package examples. I have looked in the STM32CubeF4 MCU package in directory /Projects/STM32F429I-Discovery/Demonstrations/STemWin/Binary but readme.txt file then re-directs me back to the STM32F429 Discovery page where I started. Any assistance would be very much appreciated. 

In the datasheet of the IIS343DQ it says that you should use a 10uF aluminum decoupling capacitor (chapter 'Application hints'). In the evalboard it is also shown like this in the schematic but if you look in the BOM you find a ceramic capacitor. So is the aluminium capacitor really necessary (stability reasons?) or could it be safely replaced by a ceramic one? Thank you for your help!

I'm using the STM32H757i Eval board. In STMCube repository for H7 v1.10.0, there is not a project folder for the STM32H757i eval board. I'd like to use the BSP LED/Touch drivers from the STM32H747i-EVAL project found in the cubeMX repository and potentially any others in the future. From what I could understand from UM2525, the eval boards are the same except for the actual micro-controllers.Can I start a project with the STM32H757 project and link to the folder with the STM32H747 eval files? Or, can I start a project in CubeMX for the STM32H747 and upload it to the STM32H757 allowing me to use any driver code written for the STM32H747i eval board.

Hi, I am looking all through the wiki, but I do not see any clue on using the tampers as a wakeup source.How can I configure the tampers to wake up the stm32mp1 from low power modes?Is it posible to wake up from VBAT? Or is VBAT only a energy mode to maintain the data in the memories? Can I run a piece of code in VBAT mode? If so, how could I do it? What restrictions do apply?When I say a piece of code, I mean it can be baremetal or linux or whatever it can run.Best regards,Andrés

I am trying to create a busy circle (such as the one that shows up when a web page is loading). Instead of circle I would like to use a custom image. I used TextureMapper for this. But I don't get continuous and smooth rotation of image. Image makes one rotation, slows down and stops and then restarts. I am attaching the sample project I was using. Also, image appearance distorts as it makes the rotation. Please advice.Also, please advice if there is a different way to do this.

I have STM32CubeIDE 1.9.0 and I am editing the .ioc. In the Pinout & Configuration Tab I right click and select List Pinout Compatible MCUsIt starts runningand running and running. Last night I let it run all night and it said it was 8% and there was a red message Running Low Memory. I rebooted the computer and reran it. After 4 hours it is at 50% and I got the Running Low Memory and it appears to have stopped. See attached screen shot. Error1.pngMy computer has 32 GB RAM and nothing else was running. The Task manager says 1,559.6 MB of memory is being used. I put the process priority from normal to above normal, and that did not make a difference. It says I am using a total of 7.2 of 31.8 GB (23%) of memory. I want to change the processor in my code from a STM32G031K6T to a STM32G051K8T and I was careful to use only three timers that were in both chips. Everything else was compatible. UM1718 Chapter 15 told me how to do it. I have to keep it in the same directory for git.

Is it possible to use OTP WORD 24 to 31 without enable security boot with STM32MP1 part numbers which didn't has security boot option like STM32MP157A/D?Same as above but with STM32MP1 part numbers which has security boot option like STM32MP157C/F?

Using something like STLink util or newer, command line software: Can one identify which type of STM32 MCU is connected? E.g. for use in further scripts. It doesn't help if I see it on a GUI somewhere.

Hi,Am I allowed to call the USBPD_PE_Request_CtrlMessage(), USBPD_PE_Request_HardReset(), USBPD_CAD_PortEnable() and others from different threads?I want to request data role swap, power role swap and hard resets from my interface thread.Thanks!BR, Christoph

I just updated CubeIDE to the newest (1.9 ?) version.Because under Pinout & Configuration, Pinout menu -> List pin compatible MCUs (or similar),it was stuck at 31% with a CubeIDE version from some months ago with then no CPU load anymore on CubeIDE while it was 99% before I call it "stuck".The output one could already see, with the old verison, seemed reasonable, though.Now with the newest version, I am at 50% progress bar for half an hour or so, still high CPU load (but oscillating around 50%, not 99), it shows already around 80'000 devices and most of them with clearly a useless package.Yes, I did search for "Packages: all" - because I want to get not only exactly the same package, but also different formats with the same number & functions of pins, or perhaps even some with more pins.But this "at 50% and seemingly not getting forward" view shows a lot of 20-pin MCUs for my project with a 48-pin MCU where every single usable pin is assigned a function.The "Comment" on thos
