Hi evryone,I've been trying to work on Zigbee communication for a while now, so far I've just learned how to read and write attributes. Now I'd like to try to learn how to use cluster Identify and groups, but I dont understand several thing, so I need help. For these cluster I'm working in Server.Identify Cluster (only IdentifyTime attribute)so i create my cluster, i allocate it as usual, i use the ZbZclIdentifyServerSetTime function and then i write in my attribute the value of the remaining time. what i don't understand is the part where in my code i'm going to receive the command that says "it's ok i can start the timer". i've seen that there's a start and stop structure that can be used via a callback, but i don't understand how to use it. Groups Cluster I don't really understand how to use this one.I suppose that my device will receive an order to say "I've been added to such and such a group", in which case, as above, how can I manage the reception of this order? How do

My machine is a 13th gen intel k chip with 32gb of ram. I have gigabit internet up and down. I have 2 samsung 990 NVMe pros. It has an rtx4080 My machine is perfect. Your software is ... not. I install windows 11 pro. I install CubeMX. After a minute of using it it decides to simply stop painting the screen anymore. Just like that. Bam! Unusable junk.I install windows 11 pro (again). I install CubeMX (again). After choosing new project (any of the 4 ways available to me) it hangs. Just an hourglass spinning into the abyss for eternity, whether I'm signed in or not.I'm starting to think ST can't hire people who can write reliable software. Why doesn't this work?There's no excuse for it. This is why I use zephyr, because ST's software is hot wet garbage. Think I'm wrong? Prove it by making this work on my machine. I'm so tired of wasting my time with your junk.

Hi, everyone I am Talha an Electronics student, I was recently working on making an oscilloscope using STM 32. I recently made a logic analyzer using stm 32 f103 RB. I now wanted to make a simple oscilloscope that simply displays the function generator's data. What I want is that I want to give an input signal using a simple function generator and display it on a serial analyzer. Now I don't get the problem as I tried to simply read the data and send it to USART and display it on the serial analyzer but unfortunately, there was a lot of noise, I don't get it what should I do, I have 2 STM 32 one with an ADC in it.It is a request to please help me If you can. I also need to integrate the output with a GUI I've designed using Flutter, but I would take care of it on my own.Help needed anyone with a similar experience please help.

Hi,Just yesterday on my H743VIT6 (rev. V ) on the running TFT : picture faded away...white screen.I just happened to look at the display , thinking ...ok, maybe one of the thin wires just broke now...TFT (small, 1,8" , ST7735 on 3,3V) connected /soldered about May 2022 , on SPI2 , at 48 Mbit . :)(Not touched/changed the wiring since then - so no static problem etc. possible.) Today i tried to fix the problem - but everything still connected !So took the scope to check the signals, beginning with reset ...all look ok, except SPI data !Here super slow rise time...ok, no useful signal for the TFT at 48Mb. (PC3_3 is sick ?)First check short to next pins - no, all free. Then impedance of pin unpowered : high, as cmos should be.Hmmm....try other pin: in Cube could choose PC1 as SPI2 data tx , so i changed to this and soldered the wire also here. (Soldering iron is antistatic.)Hey, TFT display ok, as before.But was the pin the problem - after 1 1/2 years running ?? So i set it as gpio ou

hi i have several questions about setting up STM32 chips as im trying to build a project which requires me to do so but ive encountered issues on my first step. im currently trying to set up my own MCU board using a STM32F722ZET6 144 however once i connect the st link it looses connection from the computer. i have used a pinout board which i then soldered wires to so it can be connected to a breadboard, the idea was not to create anything long term but to attempt to get it working. there are no issues with the reset, clock ect. parts of the circuit as it still occurs with them disconnected. for power im using a 3.3v regulator with 5v input which does create the correct power requirements with everything connected to what i believe to be correct, ive only setup the Vss and Vdd pins and not the power pins for ADC and USB. there are no shorts on the wires coming out, there appears to be none on the chip itself and i had help soldering by an engineer at work. i was planning to order some b

Tried implementing ADC conversion on STM32H563ZI Nucleo board. But, getting only a constant value like 66,67,68,69 in serial monitor(Tera term) irrespective of the given input even the i/p is unplugged getting the same values. Need a help to fix this. Thanks in advance!

Hello Community,We are selecting a high stability 12.288MHz HSE to clock our RTC on STM32G0 series MCUs.Kindly suggest if the HSE/32 which is 384kHz would be able to operate the RTC? I did not find any mentions of the maximum clock frequency for the RTC on STM32 MCUs. I understand the RTC has a prescaler, kindly direct me to the correct configurations.Clock Tree configuration using HSE with 12.288Mhz as clock input for the RTC on STM32G0Thank you!

Please let me know if I can use the Azure RTOS free with the STM32F767xx MCU and if it is free how can I use the same on my NUCLEO-F767ZI board? Please response as soon as possible. I need this to use the file system and also the ethernet/USB communication feature and other features. Can this RTOS be used for using all the wired/wireless communication peripherals available on the MCU? We need to make decisions based on this for our project. 

Hello.Three product packages are identified in the TS33's datasheet.Among these, the QFN-8 package has 5 NC pins. Is it okay to connect them to VIN or VOUT or GND?I couldn't find a additional explanation for the NC pin, so please check there is anything connected inside or it is a connection prohibition pin.Thank you.

Hello, I'm using Blue Pill Board With TMC2209 Stepper Driver To Control 3 Stepper motors. I've made a project using Arduino Mega and there were MobaTools & TMCStepper libraries available to Set Current and run multiple motors at once smoothly.  I wanted to know that, how can i do the same with Blue Pill Using STM32 Cube IDE ? Is there any special library to do the same stuff ?  Any help is appreciated. Please let me know if anyone have any answers.  

Hello, I would like to contact you because, following the code made on Keil uvision 5, I cannot get my interrupt to work.Objective of the code, turn on and off the LED (pb0) of the card with the button (pc13) on it itself.PCB Used : STM32F767ZI

Hello,We are using the USB HAL library on our custom board with an STM32H753VIT6. We have an external PHY chip (USB3300) and USB_OTG_HS. At the moment, we are using the USB to receive custom protobuf packets with a bandwidth at around 480 kbps. We have also written some additional overhead for our custom packets.Everything works mostly fine. However, after a second of running, some of our variables get corrupted. By looking at the build-analyzer in CubeIDE, I found that the RAM, namely the .bss section, was being set to garbage from 0x2400162c onwards. This was hUsbDeviceHS.ep_out[1].rem_length. I am not sure whether this variable is relevant to the problem or it is just a coincidence.I know that this could be from our own code somewhere that has a memory-leak, but I am wondering if this has been found before. I tried searching online but found nothing. Otherwise, are there any tips specific to STM32 to tracking down the cause?Thanks,

HelloI am using a Nucleo-F429 board and I was experimenting around FreeRtos.I tried to create osThread within another osThread in FreeRtos V1 but it seems that it is not calling the inside thread.When I change to FreeRtos V2, then the 2nd thread/task was called.Any reasons why ?Also, in V2, what should be the stack size of the parent thread ? Should it be bigger than the child thread ?

 Hi,I have a quick question that I couldn't find the answer to.I accidentally detached ST-LINK part of the NUCLEO-L552ZE-Q board https://www.st.com/en/evaluation-tools/nucleo-l552ze-q.I would like to reconnect the MCU part with ST-LINK using its SWD CN5 connector, but I couldn't find the pinout of the MCU part. There is no such information in the manual https://www.st.com/resource/en/user_manual/um2581-stm32l5-nucleo144-board-mb1361-stmicroelectronics.pdf.If it is necessary to solder the board, it is no problem for me, just need the proper SWD pinout.I can't wait for some hint or someone to show me that I'm just blind and this info is in the manual :)Thanks,PZdev

Anyone in STM have a datasheet for a P7C806 chip? Its part of a 2 wire bidirectional digital serial communications link, so may be a level shifter or line driver? Thanks. 

Hi allI'm currently working on getting the SD Card Interface (SDMMC1) to run on my Nucleo U575 board. I'm adapting the Fx_uSD_File_Edit Example of the STM32U575I-EV board.I'm running into problems when it comes to opening the SD Card media. In fx_media_open.c, media_ptr -> fx_media_driver_status has a value of 144 (FX_IO_ERROR). I expect the value should set be back to 0 (FX_SUCCESS) in (media_ptr -> fx_media_driver_entry) (media_ptr) (at comment "/*Invoke the driver to read the boot sector.*/). In my case, it isn't reset to 0 but stays at 144 instead.Unfortunately I can't find the linked function to have a deeper look debugging. Could someone please assist and tell me where to find this function? Or maybe even telling me, what setting the error could be caused by :Dcheers

Is my assumption right?When you have code like this: *(hospi->pBuffPtr - 1) = SPI3->RXDR; and you set a breakpoint on this line (so that is stops before this instruction is executed),but you have the SFR page open, to see the registers of the peripheral device, here SPI3, including the content of "register" RXDR (which is a FIFO!):it "will" go wrong?What could (seems to) happen:the open SFR page reads also the register RXDRbut this is a FIFO!so, the debugger view "grabs" the data from the FIFO (and it looks correct what you see as data there)and when you continue: you do not get the same value from this register (FIFO): it was read already read (and removed from the FIFO) - your variable assignment "goes wrong"So, my conclusion would be:if you have code where it reads from a FIFOset the breakpoint ONLY after the read instruction (not before or at the instruction reading "also" from this FIFO register)Assume, that a debugger view (SFR page open and displaying the content

Hello community,my sths34pf80 is connected with a wireless MCU through I2C in fast mode. during the initial process the function " sths34pf80_presence_threshold_set(&presenceHandle, 200); " is called, sometimes there is no problem, the sths34pf80 can be successfully initialized, it can detect presence and motion.But it also happens oft: if the ctrl1.odr is 8, then it hangs by excuting sths34pf80_odr_safe_set(if ctrl.odr is 0, the initial will be successful.)int32_t sths34pf80_presence_threshold_set(const sths34pf80_ctx_t *ctx, uint16_t val){  sths34pf80_ctrl1_t ctrl1;  uint8_t odr;  uint8_t buff[2];  int32_t ret;  if ((val & 0x8000U) != 0x0U) {    /* threshold values are on 15 bits */    return -1;  }  /* Save current odr and enter PD mode */  ret = sths34pf80_read_reg(ctx, STHS34PF80_CTRL1, (uint8_t *)&ctrl1, 1);  odr = ctrl1.odr;  printf("threshold set...1:%d\n", odr);  ret += s

Hello all, I am using the STM32U5A5QJ in a project and I had a question about some of the wake-up modes. I would like the microcontroller to be in stop mode 3 most of the time until it receives an interrupt from a sensor to return to normal mode. The data sheet seems to specify two ways of doing this and I’m wondering which is correct or if both can be used. In Table 9. STM32U5Axxx modes overview it says the wake-up source for stop mode 3 is one of the 24 WKUPx I/O’s.There is also a section under Extended interrupt/event controller (EXTI) where it says “The EXTI wake-up requests allow the system to be woken up from Stop modes.” They both seem to say that they can be used to wake-up from stop mode, is this correct or should one be used over the other? Thanks for your help,
