Hi I'm not very experienced with Zigbee, but I have a ZGPD power measuring device on my desk I'd like to get the data from. With a 802.15.4 sniffer i see he's asking for a channel (command 0xe3) within the first 5 minutes after startup. He's also broadcasting data (ZGP stub NWK header data) every 5 seconds, I guess some kind of commissioning request. I've never seen any kind of response from my WPAN coordinator server sample running on STM32WB55.Is it possible to handle this devices with the current WPAN middleware? Couldn't find any samples.Best regardsArmin see also: Green Power Device cluster missing in CubeMX ?

Hello everyone,Is there an example project available to make the ST25R95 on the X-NUCLEO-NFC03A1 shield work with the NUCLEO-G071RB?

Hi, https://community.st.com/t5/stm32-mcus-products/configuring-ppp-on-stm32f407disc-with-lte-modem-via-usart-using/m-p/728673#M262741 This continues the previous thread discussing the PPPoS implementation for the STM32F407. I successfully established a PPP connection and obtained an IP address. However, my ICMP ping to Google did not receive a successful response. Please check the code snippet below for any necessary changes.   void PPPosClientThread() { osSemaphoreWait(pppos_mutex, PPPOSMUTEX_TIMEOUT); pppos_task_started = 1; osSemaphoreRelease(pppos_mutex); int gsmCmdIter = 0; int nfail = 0; printf("GSM: Starting Modem thread\r\n"); char* data = (char*) malloc(BUF_SIZE); char PPP_ApnATReq[sizeof(CONFIG_GSM_APN) + 24]; sprintf(PPP_ApnATReq, "AT+CGDCONT=1,\"IP\",\"%s\"\r\n", CONFIG_GSM_APN); cmd_APN.cmd = PPP_ApnATReq; cmd_APN.cmdSize = strlen(PPP_ApnATReq); //_disconnect(1); // Disconnect if connected // FOR testing osSemaphoreWait(pppos_mutex, PPPOS

Hi ST,I wanted to validate/confirm our Calibration procedure.  When we calibrate prior to calibration we set timing budget and intermeasurement to what they are normally when our code boots up.  So,  during calibration we do the same.  Can someone please confirm this is the correct procedure? Meaning,  should we set TimingBudget, InterMeasure, ROI and ROI Center to "anything" prior to running calibration or are we correct in how we are doing this. .....VL53L1X_SetTimingBudgetInMs(33);VL53L1X_SetInterMeasurementInMs(40);VL53L1X_SetROI(4, 4);VL53L1X_SetROICenter(191);status = VL53L1X_CalibrateOffset(TargetDist, &Offset);..... Thanks,Will   

I wonder, if it is possible to build a Zigbee Green Power Proxy and ZGP Sink with the STM32_WPAN v1.0.I couldn't find any documentation neither any source code samples.I did find some hints about Zigbee Green Power:1. https://wiki.st.com/stm32mcu/wiki/Connectivity:Zigbee_certification_process:2. In STM32CubeIde:I also tried to call Zgp functions found in zigbee.zgp.h like ZbZgpDeviceServerAlloc() or ZbZgpDataReqCallback(), but I got a linker error "undefined reference". Seems these functions are not provided by the library.So I'm not sure can I achieve the goal I try to with the tools I use.If someone (ST employee) could answer my question, it would save me a lot of time.Armin

Hi All,I'm having a terrible (fun) time trying to get the DP83848 to work with the STM32H743 (RMII).No packets, no interrupts, nothing. - it's just dead to the world.I can get things working with the LAN7842 and I can get the DP83848 working with the F7 series no problems.I have tried everything I can think ofPlayed around with different SRAM  and MPU configs - all set up correctly I  think (as per LAN7842 etc)I've tried importing the DP83848 stuff from the F7 HAL librariesI've modified the LAN7842 headers to 'work' with the DP83848tried countless examples and ideas from this forumspent nearly all week on it!I read the excellent post " How to create a project for STM32H7 with Ethernet and LwIP stack working" byfrom @Adam BERLINGER where he states the followingunfortunately when LAN8720 is used in REF_CLK_OUT mode (RMII clocks generated by PHY), the timing is not compatible with STM32H7. In that case the RXD output hold is 1.4ns minimum on PHY side, while STM32H7 requires at l

Hello there. I am working on STM32G030 based FW. It appeared the TIM1x_CH1N doesn't work. I found out this part of code doesn't initialize negative channel(stm32g0xx_hal_tim.c). Moreover it may skip all channels configurations. It seems to be a hard coded part that initializes only positive channel with defined CxP and CxN options if so it really skip user predefined ones.    Could you fix this issue and update HAL driver sources?   Thank you in advice.

We are having issues with the VL53L4CD Time of Flight Sensor.The sensor works properly after initialization, but after some measurements it starts having problems. It either stops ranging or returns a ranging result similar or equal to the previous one, while returning data ready TRUE and ranging OK (Results status 0).  Here's a description of what happens when the sensor still ranges but gives wrong results (second case):- We take an initial ranging (distance from an object)- We move the sensor away from the object- We ask for a ranging: the result is similar or equal to the initial measure.- Now we move the sensor away again- We ask for a new ranging: the result is the one we expect after the first movement. Some detailed info:- The sensor initialization is copied from the "ranging basics" example attached with the drivers.- We changed the interrupt to active high by changing the value of register 0x30 in VL53L4CD_DEFAULT_CONFIGURATION (VL53L4CD_api.c)- We se

Greetings Sir/Mam,I have some questions about STM32 MCU Chips. Sir/Mam, I want to know if the STM32 MCU Chip Programming is possible, you may view the video on- https://www.youtube.com/watch?v=ndEeFQ5mi_g&t=106s  , to get about my question. Sir/Mam, I have- STM32U595RJT6Q MCU, it would be very helpful if you could please tell if Chip Programming of this product(s) is possible, and if possible, which Application Notes, Manuals are required for doing it, also, if I design the Breakout Board for this MCU, then is it possible to program it using STM32 Development Board with any MCU or we require the specific Development Board with this specific MCU only, and if their is any other very critical & essential thing(s) to keep in mind while doing all this, if anything among them is possible. Thanking You, ANKUR.

I had debugging problems with a H7 target, and by stepping thru the boot process I found the following line in SystemInit(): /* * Disable the FMC bank1 (enabled after reset). * This, prevents CPU speculation access on this bank which blocks the use of FMC during * 24us. During this time the others FMC master (such as LTDC) cannot use it! */ FMC_Bank1_R->BTCR[0] = 0x000030D2; At this stage of the boot process, the FMC power is not enabled, and thus reading or writing the register has no effect. Am I overseeing something or is this line for confusion?

When I tried to open the declaration, to see how function works, STM32CUBE IDE does not automatically open the respective .c files in which function declarations exist.Could you pls point me to the right direction ?  

All my code works on RTOS.When I enable D-Cache，fs_mount() from FATFS on SD card returns FR_NO_FILESYSTEM，SD card can not work.When I disable D-Cache, fs_mount() returns FR_OK, SD card can write and read.But at the same time , i need to use Ethernet on my device . When I close D-Cache, my Ethernet can not work.How can I resolve these two conflicting issues？

这是我烧录成功的画面，连接上stlink后板子的LD4是红绿交替闪烁的。烧录成功也是一样，板子没任何变化。程序是没有问题的。串口没任何输出。This is the picture of my successful burning, and the LD4 of the board flashes red and green alternately after connecting to ST-Link. The same is true for successful burning, and there is no change in the board. There is no problem with the procedure. The serial port does not have any output.Translated using Google Translate by Community team. 

Hi, I am using STM32h735g-dk development board, STM32CubeProgrammer and ST link to flash the development board. I tried to flash program the development board using the ST link and STM32CubeProgrammer. Once, it got programmed, but after some time, I tried to program the same board again using the USB cable with the onboard ST link programmer; it did not get programmed.Now its giving me this below error in STM32 Cube Programmer and its not getting connected."15:56:35 : UR connection mode is defined with the HWrst reset mode15:56:40 : ST-LINK error (DEV_USB_COMM_ERR)15:56:40 : Error: Problem occurred while trying to connect" Checked on the device manager, and there on ports "board is not getting detected" but is showing me on the Universal Serial bus devices. Screen shot attached below for your reference.And check on STM32 Cube IDE, here also the same issue is "No device found". Kindly let me know, what would be the issue and please revert me back if there are any add

Hi. I have a collection of STM32VL_Discovery boards, and I want to put them to good use. I am looking for the STM32100B-EVAL software library package. The latest downloads by CubeMX do not include anything for the 100B-EVAL. I am particularly interested in finding the application demo with the menu selection of all the apps supplied.Is this still package available for download for those of us still finding use for these older boards.Thanks KV

Hello awesome people of the STM community! I'm working on a GUI project for the STM32H750B-DK, currently following the board bring up steps. I know that I could just use the generated code by TouchGFX template for the STM32H750B-DK. However, I have a few reasons for avoiding this:Being an engineering student I want to learn as much as I can form this project, by doing board bring up I can learn more step by step then just pressing a button and have it magically work (though magically work is getting more and more appealing) .The GUI is only one aspect of the project, I want to have accesses to a debugger in my preferred IDE (CLion) and not be reliant on constantly uploading through TouchGFX. I would much rather finish the GUI and upload the assets to external flash then just work in internal flash for the remainder of the project.I want to get the skills to do a board bring up for when I need a GUI for a custom board.Again being a mere engineering student I don't wa

I have build a IAP bootloader at 0x8000000 and test with a simple blink app at 0x8040000 which works fine but if I add FreeRTOS for the same blink app at 0x8040000 its not working. It jump to the blink application but it doesn't pass the SystemClock_Config() function while under debugging.

I created a qt quick app onqt  version 6.7.3 for the stm32mp157f-disco. I was able to test using qt creator and boot 2 qt on the target board and it worked just fine. Now, I'm in process of building the linux image for the target. Since I don't fully understand how to use yocto, and it seems there's no support from st side for qt on stm32mp15, I decided to go the other path, using the boot 2 qt. I created a custom recipe with my qt app and was able to bitbake this recipe. Now, I'm trying to build the entire image but I'm getting the following error: | cd /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/build/src/core && /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/recipe-sysroot-native/usr/bin/ninja -C /home/vboxuser/yocto/build-stm32mp15-disco/tmp/work/cortexa7t2hf-neon-vfpv4-poky-linux-gnueabi/qtwebengine/6.7.3/build/src/

I'm following the starter and distribution package for the stm32mp157f-dk2.A few weeks ago I was able to flash my target board with the starter package and can confirm it initialized the st gui and so on.I also added the usb gadget in my vm as stated on another post.Now, I'm trying to flash the st-image from the distribution package but its not able to reconnect.\I'm using an iphone quick charge that outputs 5v 3A and it worked for the starter package. I tried with another power supply just to confirm that's not the issue and I got the error in st-link. Which means my iphone quick charge is ok ***************** * ERROR USB TYPE-C connection in unattached mode * * Check that USB TYPE-C cable is correctly plugged * * Current too low, use a 3A power supply! * ******************  These are the logs from cubeprogrammer: vboxuser@ubuntu:~/stm-envirionment/Distribution-Package/build-openstlinuxweston-stm32mp15-disco/tmp-glibc/deploy/images/stm32mp15-disco$ STM32_Programmer
