 Hello,I hope this message finds you well. I am currently managing over eight Zigbee devices connected to one Coordinator in a star topology fashion (8 or more End devices to one Coordinator). However, the manual procedure for flashing new firmware is proving to be time-consuming. Consequently, I have decided to implement Zigbee OTA clusters to facilitate over-the-air firmware updates.Regrettably, I am facing challenges in finding comprehensive guidance on this matter. I would greatly appreciate your assistance in providing examples or references related to OTA clusters.Thank you in advance for your support.Best regards,Naani Ch 

GreetingsI am trying to read from the FIFO of the LIS2DW12. What confuses me, is that reading through the datasheet, there are only registers which indicate the number of unread samples in the FIFO (FIFO_SAMPLES (2Fh)), and a control register FIFO_CTRL (2Eh). What I am expecting, are dedicated registers from the conventional OUTPUT registers which a device like the LSM6DSOX has. The LIS2DW12 does not possess such registers, thus what address do I do a read from, that will be able to provide the 32 samples it is able to hold in its FIFO? Will it be the conventional OUTPUT registers?Any help would be appreciated.Thank you.

I found the DMA request mapping of the F4 series on ST's official website. With this form, I can configure DMA on zephyr. My problem is that I cannot find the DMA request mapping of STM32WBA52CG. Can you provide me with one? Thank you.The device tree file requires channel and request parameters. 

Hi, i`m new to stm32. I have a STM32469I EVAL Rev C Board And Using STM32CubeIDE. I downloaded STM32CubeF4 Firmware Package V1.28.0 from CubeMx but, I can`t find OTG Firmware Upgrade Example for STM32469I EVAL. Where can I find OTG FirmwareUpgrade Example for STM32469I EVAL?

Hello,I need to detect input when it goes over REF/2 (1.65V). I do supply VREF+ pin with 3.3000V.My signal has offset of 1.2V, and it will go over 2V when I apply signal to it.Everything is working, but it has unexpected behavior. I can only use negative input as VREF, if I set it to anything else, I get constant 1.I tested my VREF+ input, and it is 3.3000V ( 0.5% REF chip). Also testes signal on PB0 pin, and it is 1.200 or >2.00VWith debugger I do see BRGEN and SCALEN bits enabled.  But it just does not act as it suppose to. What do I am missing. is Vrefint needs to be enabled? I was unable to find this information... Also I am using LL libs.      Does any one has experience regarding this ?void EXTREF_DETECT_Init(void) { LL_GPIO_InitTypeDef GPIO_InitStruct = {0}; LL_APB4_GRP1_EnableClock(LL_APB4_GRP1_PERIPH_COMP12); LL_AHB4_GRP1_EnableClock(LL_AHB4_GRP1_PERIPH_GPIOB); LL_AHB4_GRP1_EnableClock(LL_AHB4_GRP1_PERIPH_GPIOC); GPIO_InitStruct.Pin

Hello. I was powering up my NUCLEO-F446ZE microcontroller board using an external power supply of 5V. I set the jumper JP3 to E5V. I made some changes in the code and tried to connect the board to the USB to burn the code to its memory. I forgot to remove the external power supply and simply removed the E5V and connected it to U5V. I suddenly inspected that smoke came out of regulator IC U6. Now whenever I am connecting the board to the USB, the over current LED LD5 is blinking and as a result U4 is getting heated up a lot. I know that my Nucleo board has been fried up. Have I made a big mistake with the input power? Can anybody explain me that? Is there any way that this board can be made functional again? Thanks!

Hi to all,my STM32CubeIDE 1.12 installation does not complete the update to version 1.14.During the update the error returns:An error occurred while collecting items to be installedsession context was:(profile=STM32CubeIDE, phase=org.eclipse.equinox.internal.p2.engine.phases.Collect, operand=, action=).No repository found containing: osgi.bundle,javax.annotation,1.3.5.v20230504-0748In this condition I noticed that the projects generated with the MX cube are not loaded or opened in the IDE (the cubeMX has been updated). I don't know if the two things are connected.Do you have any suggestions ?

Dear Community member,We have developed a PCB for Air pollution measurement using STM32G473VET6 MCU. We were able to flash the program successfully, but we didn't receive any output from GPIO, UART, USB, etc. None of the peripherals are working except VCC, GND, and JTAG. Please guide us on how to resolve this issue.best regardsNeerajFounder & CEORadifonics Solutions Pvt LtdIndira Nagar, Bangalore-560038

Hi, i am using Timers to control the intensity of a RGB LED. I need help with a code because I don't know why i have to do this thing.I have these lines:TIM1->CCR1 = Intensity; For Red ColorTIM1->CCR2 = Intensity; For green colorTIM1->CCR4 = Intensity; For blue color but it doesn't work while calling (&htim1, TIM_CHANNEL_4);But if i do this:// Set alternate output for CH2, disabling main output (no need of it because already disabled, but just in case)CLEAR_BIT(TIM1->CCER, 1 << 4);SET_BIT(TIM1->CCER, 1 << 6);// Set alternate output for CH1, disabling main output (no need of last thing but whatever)CLEAR_BIT(TIM1->CCER, 1 << 0);SET_BIT(TIM1->CCER, 1 << 2);HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_4); It starts working. This last code is not mine, this is why i am asking this. Why i have to use clear bit, and do this shifts? I have no idea with this.  Thank you so much.

Hi,I have been experimenting with secure boot on the STM32H573I-DK, but I can't perform a regression anymore.While adapting the example code (OEMiROT) to my own version, I am currently in the situation where the device is "provisioned" (0x2e), but I have lost the keys/certificates because they were accidentally overwritten during my experiments. So I can't open up the debug access port anymore. TrustZone is enabled (0xb4).Currently with the STM32CubeProgrammer I can connect to the device in hotplug mode:And I can read out the registers:After doing some research for other ST platforms (the STM32U5 for example), it seems to be possible to "unprovision" the device using the STM32CubeProgrammer. However, changing both the PRODUCT_STATE and TZEN registers to 0xED and 0xC3 respectively results in an error:Additionally, the STM32CubeProgrammer manual documents a possibility to disable TrustZone via CLI (https://www.st.com/resource/en/user_manual/um2237-stm32cubeprogrammer-software-description

Hello, I'm trying to validate a CNN model using X-CUBE-AI and the STM32H747I-DISCO board with the microcontroller STM32H747XIH6. The Flash memory size should be 2MB and 1MB of RAM. However, the memory limit is bellow the expected one. For instance, the Flash is limited to 1MB (please see the picture from the attachment).Can someone please help me with an explanation?Thank you very much!

Hello, I looked over the internet and couldn't find the firmware, even tried older versions of mcsdk, no example board of ptool1v1. In 2022 similar post was made that was looking ptool1v1 firmware and answer was redirected to the page that doesn't exist anymore.

Hi, can i control a motor with Algobuilder? or the software is only used to visualize the data? 

Hi, ı have a  question about flash size difference between STM32F107RB nd STM32F107RC. Documentation says that stm32f107rb has 128kb flash memory and stm32f107rc has 256kb flash memory size.  DOCUMENT NUMBER:PM0075 says that STM23F107 are connectivity line mcu and it has 128 page with 2kb memory on page number 9 of document.  When ı calculate, it makes 256kb with 128 page with 2kb. I am using STM32F107RB  and ı tried to write to last page which is page 127 starts from 0x0803F800. I have succesfully write and read something from this address without any problem. But how can it be possible? Stm32f107rb has 128kb memory there should be maximum 64page with 2kb page size. There should be something, could you please help me about this issue ? If stm32f107rb has 128kb flash memory, how can it be possible to write and read from 128.page which is 2kb flash memory ? there should not be any page after 64.page for stm32f107rb ? 

Hello,Please, I am working on a Custom Project with STM32H7 platform and I am using a NAND Flash for Data Storage (W25N01GVZEIG). I can execute correctly all commands except :(32h) Quad Program Data Load . I can write using (02h) Program Data Load with SPI mode with no issues, but once I switch to Quad mode (32h) the data written is not correct, seems there is some bits corruption.{0x11,0x22,0x44,0x88} is written {0x91,0x22,0x04,0x48}. I suspected the pinout first but the Quad read is working fine. I saw a similar question QSPI of STM32L496A but didn't fix my issue.Could you support on this?Thanks,Ayoub

I am in progress of learning Can Bus protocol and this problem destroy me please help me :) Here is my code  /* USER CODE BEGIN 0 */ CAN_TxHeaderTypeDef pHeader; CAN_RxHeaderTypeDef pRxHeader; CAN_FilterTypeDef sFilterConfig; uint32_t pTxMailbox; uint8_t count=0; uint8_t rcount=0; /* USER CODE END 0 */         /* Initialize all configured peripherals */ MX_GPIO_Init(); MX_CAN1_Init(); /* USER CODE BEGIN 2 */ HAL_CAN_Start(&hcan1); // Activate Interrupts HAL_CAN_ActivateNotification(&hcan1,CAN_IT_RX_FIFO0_MSG_PENDING); // set transmit parameteres pHeader.DLC = 1; pHeader.IDE = CAN_ID_STD; pHeader.RTR =

I'm developing a board with an STM32L452 and would like to find out if I can improve power consumption while it remains connected via USB (as a device). I've tried putting the device to sleep using the following code: while (1) { // ... do stuff HAL_SuspendTick(); HAL_PWR_EnterSLEEPMode(PWR_MAINREGULATOR_ON, PWR_SLEEPENTRY_WFI); HAL_ResumeTick(); } My configuration for USB is CDC and has SOF, Low power, and Link power management enabled. I've tried changing these settings, but none of these seem to make a difference. The issue is the USB IRQ keeps the device from staying in sleep mode, so there's very little difference in power usage overall. I would like to keep the USB connection, otherwise the host pc software would have to poll and try reconnecting constantly. I know the host can tell the device to suspend, but is there a way the USB device can tell the host to pause and continue if either the host or device have something to communicate? Sort of like SDMMC can d

I am casting a Byte array (results from ADC) to a long, but occasionally - about 1:100000, it get the sums wrong.  I've got to the line in the code where it goes wrong, and it is when it is casting a byte array to a long (I use union Method). //Signed ADC Value - so 24-bit value can be shifted in union { uint8_t b[4]; int32_t l; }I32ADCValue;    //Populate the Raw mV Array for(i=0;i<8;i++)//Loop for each channel { I32ADCValue.b[3]=ads1298rData.ADCMsg.Channel[i][0]; I32ADCValue.b[2]=ads1298rData.ADCMsg.Channel[i][1]; I32ADCValue.b[1]=ads1298rData.ADCMsg.Channel[i][2]; I32ADCValue.b[0]=0; //Channels are not in sequence - create temporary array here. mVx[i]=(I32ADCValue.l*Gain_mV); }  When I run the debugger, it is having too bit a blue in I32ADCValue.l - in fact where I set .b[0] to 0, it is not after it has cast it.....any clues? 

pls suggest a example for reader/writer/formatter for NFC03A1are there any writer example code for RPi similar to poller example ?https://community.st.com/t5/st25-nfc-rfid-tags-and-readers/x-cube-nfc3-for-stm32cube/td-p/591339i didnot find the source for the same..i did notice X-CUBE-NFC3 , Ver 2.1.0 is availablehttps://www.st.com/en/embedded-software/x-cube-nfc3.html  

Hi to all, I'm starting a new project with ST25R95 and X-NUCLEO-NFC03A1 as demo board. I have two question about example usage:1) I can't find X-CUBE-NFC3 package in cube MX (only 4 and 6 are avaiable). How can I add this package to Cube MX configurator ?2) I downloaded the package X-CUBE-NFC3 from the site, but the import of the examples for the F401RE board is not successful (as for all the ST examples). I entered all the dependencies manually, but the rfal_dpoTbl.h file is missing. Where can I find it? Thanks to all.

For implementing our own hardware, I'm using the Board description of a B-G431B-ESC1 as a template.The "motorDrives" object declares some properties, like "maxRatedCurrent", "minRatedVoltage", "maxRatedVoltage" and "resistorOffset".None of those are described in the Motor Control Boards Description documentation.What are those properties for?

I have a uart peripheral whose baud rate can only be set to 3.125M. However, the baud rate of another uart peripheral with the same clock configuration in the project can be set to 12.5M. I want to know what the baud rate limit is based on？ How to increase the baud rate from 3.125M to 12.5M？
