Hello, i am looking into doing wireless thermostats using Zigbee who communicates with controlers. The controlers activate and desactivate valves to heat the house. What would be the configuration of the microcontrolers and how can i program my application. its a custom circuit board i have made i only need to configure and program. I have activated the STM32_WPAN and i dont know how to configure the Zigbee after i activate it, i cant find applications on the internet.Thank you!

I recently purchased a VL53L7CX and VL53L8CX, so I wanted to test the Motion Indicator functionality for each zone to show if the targets moved and how they moved via SPD of the software by STM except that there, when two people present themselves in front of the sensor, we only see one personHow to do it?

Hi all,I'm struggling to get the ST bootloader on a STM32L431KUB to communicate with a STLINK-V3SET via CANBUS using the STM32CubeProgrammer, the reported error is ST-LINK error (BRG_CAN_ERR) Establishing connection with the device failed.I have made an adapter board with a MCP2551 transceiver which is connected via flying leads on CN9 of the STLINK-V3SET. I can connect a CANBUS analyzer to the output of this and see that the STLINK is sending messages to id 0x79, so I am confident this is working as expected.My target is a custom PCB with an 8Mhz external clock and a TCAN322 CANBUS transceiver, which functions correctly when I load my application software through the SWD interface.  I can also see that the uC is going into the bootloader when the BOOT0 pin is pulled high or the device memory is blank, by using the SWD interface and checking the program counter is in the 0x1FFFXXXX range.  However despite seeing the expected messages on the CANBUS and seeing ac

So I know if I use the STM32CubeProgrammer there's an option to skip flash erase before programming which is great. However, I'm trying to debug some code and I need to prevent flash erase, because I have some code in a sector which I need to keep, but also program some new code in that same sector.By using the 'ST-LINK_gdbserver --help' command, there's no option/argument which I can use to prevent the flash erase before programming. I tried using the '--skipErase' option mentioned here:https://community.st.com/t5/stm32cubeprogrammer-mcus/skipping-flash-erase-with-stm32-programmer-cli-and-stlink-v3/td-p/608809  But it didn't work for me:'/opt/ST/STM32CubeCLT_1.18.0/STLink-gdb-server/bin/ST-LINK_gdbserver -p 50000 -cp /opt/ST/STM32CubeCLT_1.18.0/STM32CubeProgrammer/bin --swd --halt --skipErase -m 0PARSE ERROR: Argument: --skipEraseCouldn't find match for argument' It seems like the --skipErase command is specific for the programmer, but there's no way to invoke it from t

I want to use the STM32F407 to implement the NanoEdge AI Library for Anomaly Detection (AD) tasks.The documentation mentions nanoedge.ai's method for backing up and restoring the library knowledge using the .ld file in a Linux environment. I want to know how to perform this backup operation in Keil.

Hello,I'm working with the STM32N6570-DK board and using X-CUBE-AI to run quantized neural networks converted from ONNX models.I'm trying to better understand which parts of the model are executed in software vs. hardware, specifically on this board, and what determines that split.My Observations:1. ResNet-8 Model (custom quantized)When I validated a quantized ResNet-8 model, the output during target validation showed:Total number of epochs: 16 of which 2 implemented in softwareepoch ID HW/SW/EC Operation (SW only)epoch 15 -SW- ( Softmax )epoch 16 -SW- ( DequantizeLinear )So, almost everything was offloaded to hardware, except for the final softmax and dequantization — which I expected.2. Simple Model Quantized via ST Developer Cloud However, when I tested a very simple model (shown above), quantized through the ST Developer Cloud, I saw this:Total number of epochs: 5 of which 3 implemented in softwareepoch ID HW/SW/EC Operation (SW only)epoch 2 -SW- ( DequantizeLinear )epoch 3 -S

hi all, I am using STM32F733xx and i want to read the Vout i will be monitoring is between 1-5v, to read that i have used analogue pins PG13, PH3 ,PH2,PG14, PE2,PE3, PE6, PE4,PE5,PF1,PF0,PF2I already have the PCB so i cant change the design can anyone suggest any solution to this?Looking for some firmware based solution to this problem. Thanks in advance,Regards,Sal

Split from EEPROM Emulation: meaning of the VirtAddVarTab as this is a new question.The eeprom emulation in my simple trial sofware is working fine. The code is quite small.I tried to use this software inside a more complex program, larger than 64K, and the system hangs.From what I have understood only the first 16K are available for program with the suggested setup.It is possile to have a setup for eeprom that allows to use more flash program memory?

I'm developing a UI on STM32H750 using TouchGFX with a 1024x768 display. I'm experiencing significant performance issues with touch responsiveness when displaying graphs.My UI Structure:Base screen (screen1) with a menu buttonWhen menu button is pressed, a menu container is displayed on topThe menu container has a graph button which opens a graph container that overlays on topThe graph display uses a CacheableContainer with multiple static graphsThe Problem:When the graph is displayed, touch response becomes extremely slow. I've used CacheableContainer which helped slightly, but issues persist.In the simulator, I discovered that during every tick, the entire screen (full rect 0,0,1024,768) is being redrawn unnecessarily. The CPU usage spikes when the graph is displayed.Here's the call stack when debugging:#0 0x005d3da7 in touchgfx::CacheableContainer::setupDrawChain(touchgfx::Rect const&, touchgfx::Drawable**) ()#1 0x005d3aa0 in touchgfx::Container::setupDrawChain(touchgfx::Rect co

I have a scroll wheel languageSelectorWheel with several items. Every item is a container languageSelectorItemOn the container I have a toggle button. When I click any toggle button, I want to send a trigger on the view of the scroll wheel to execute a function. On the toggle button I have added an interaction onClick via TouchGFX that emits the trigger languageChanged. The trigger is set on the languageSelectorItem containerOn the view where the languageSelectorWheel is added, I have set the callbackvoid languageSettingsView::languageChanged() Unfortunatly, it seems it is not called when i toggle the button (settings a breakpoint on the line that call emitLanguageChangedCallback(); in languageSelectorBase where void languageSelectorBase::buttonCallbackHandler(const touchgfx::AbstractButton& src) is defined enters) My thought is that because the trigger is set on the container, it won't be passed to the view

We are currently seeking layout recommendations for the ST25R3916 and ST25R3918 chips.On the Transmitter Side:ST25R3916B → Power Amplifier → Matching Circuit → AntennaOn the Reciever Side:Antenna → Matching Circuit →Power Harvester → ST25R3918The implemented power amplifier is a Class E amplifier configured in push-pull mode  (We intend to transmit power along with NFC communication)The matching circuit has been designed using the ST25R Antenna Matching Tool.We are using a differential configuration, and as such, the matching elements have been placed symmetrically on both arms.A provision for a balun has been included between the power transmitter and the matching network.We have the following queries:The ST25R Antenna Matching Tool provides both single-ended and differential matching options. For the single-ended configuration, we understand that the PCB trace impedance should be matched to 50 ohms, whereas for the differential configuration, the PCB traces should foll

Hi,we try to load a small program to RAM area starting from address 0x20008000 with STMCubeIDE and USB DFU and select start address 0x20008000 ( In debugger we can see that program is load to 0x20008000).The download is successful, even so setting start address is successful, but the start of program is not successful.If we download and start the same program with ozone debugger there is no issue. It runs as expected.Used controller: STM32L45x/L46x, MCU, Flash size 512.Is there any idea what I can check?Best Regards,Claus

Hi everyone,I am working on LoRa point-to-point communication using the STM32WLE5CCU6 and trying to run the PingPong example. However, I haven't been successful so far.I would appreciate any guidance on whether I need to modify any pin configurations or make changes to the PingPong example before uploading it to the MCU. Additionally, I am using this IC in the RAK3172 module. Has anyone here developed their own circuit for it?Any help or suggestions would be greatly appreciated!Thank you.

The evaluation board, STM32H743I-EVAL, is used. Where can I find the sample code?I would like the source code.

Hello everyone,I'm experimenting PCROP activation on stm32h743 following this ST-tutorial: https://youtu.be/7Wr90XFA8_Q?si=tDpqUtMdin9Oyn-PThe activation works fine but i cannot disable PCROP using CubeProgrammer.I did a RDP1 to RDP0 regression with DMWP1 checked but the PCROP is still activeAfter RDP regression i can se that the unprotected flash are is erase:But not the protected one:I can also not change the option bytes anymore, even RDP0 to RDP1 does not workHow can i recover from this situation ?@Jocelyn RICARD, @Fred 

Hello,I would like to confirm the correct procedure for measuring antenna impedance using a NanoVNA. The chip under test is the ST25R3916.I came across the post titled "How to Measure Antenna Parameters According to AN4974 with NanoVNA," which was very helpful in understanding the general procedure. However, I would like to request a few additional details to clarify certain aspects of the measurement:Following is my differential antenna circuit.Since the NanoVNA supports only single-ended measurements, I am considering the following approach:I plan to remove the voltage divider blocks (highlighted in red) and disconnect the ground at the center point marked with “?”. This way, the VNA will only see the differential network, without any path to ground.Could you please confirm if this approach for impedance measurement is correct?If not, I would appreciate your guidance on how to properly measure the impedance of this differential circuit using a NanoVNA. RegardsSuraj

I'm working on a bare-metal project using an STM32F407VET6 (generic “black board” from China - https://stm32-base.org/boards/STM32F407VET6-STM32-F4VE-V2.0.html). I'm trying to trigger ADC1 conversions using TIM2_TRGO (timer trigger output), but the ADC only works when using SWSTART. I've done extensive testing and debugging to isolate the problem. Here's what I found:What works:ADC1 works with SWSTART: I can read from channel 1 (PA1) manually and see the expected values.LED debug: PD12 lights up if the ADC reads a value above 1000.TIM2 generates update events: Confirmed by enabling the TIM2 UIF interrupt and toggling PD12 on each update.Trigger configuration:EXTSEL = 4 → TIM2_TRGOEXTEN = 1 → rising edgeForced trigger via TIM2->EGR |= TIM_EGR_UG does not trigger the ADC.VREF+ is connected to 3.3V, and VREF- to GND, with a 100nF decoupling cap.TIM2_TRGO is confirmed to work via IRQ debug (PD12 blinks).DMA is configured (when enabled), but never triggers → PD12 never toggles. Debu

Hi,Thanks in advance for your attention.I'm wondering if any examples are available about transmit and receive raw ethernet frames.The examples in STM32CubeH5 use the TCP/IP stack NetXDuo and transmit packets built on the upper layers of the stack and pass received packets to the upper layers.How could I transmit/receive single raw ethernet frames to handle a custom layer 2 protocol?Comparing with what is done by NetXDuo:In transmission (as in _nx_driver_hardware_packet_send) I could build the ETH_BufferTypeDef with the next pointer to NULL and send a single buffer?In reception (as in _nx_driver_hardware_packet_received) in HAL_ETH_ReadData, the HAL_ETH_RxLinkCallback must be implemented to chain all received packets from the Rx Descriptors? Is not possible to receive and process a single ethernet frame? It's confusing to me... And what is the purpose of HAL_ETH_RxAllocateCallback, should it be implemented?An alternative could be handling a custom layer 2 protocol in Net

Hello, I made a custom board using the STM32C031K4T6. I have tried several times now to connect to the chip using STM32 Cube IDE and the STM32 Programmer, both didn't work. The ST-Link gets recognized. I have tried different combinations regarding the Boot0 pin and the reset pin but I can't get it to work. I get the error message that no target was found. I also attached the schematic for the board.    

I want to add the STM32 sequencer utility (https://wiki.st.com/stm32mcu/wiki/Utility:Sequencer) into my STM32L072 project.I have downloaded the STM32Cube_FW_L0_V1.12.3 package for STM32L0 but there is no "sequencer" folder for the utility. Besides, there is no option in STM32CubeMX to add the sequencer utility.Where can I find the STM32 sequencer utility for STM32L0?Thanks! 

Custom board will not run without debugger.  With debugger removed and cycling power I have manually touch NRST to ground to get it to run.The NRST is only connected to SWD pin, but when debugger is removed it is not connected.  Theis is no ST-LINK on the board.  The NRST does measure 3.3 volts after power up.I do use BOOT0 pin as an output.  It is configured low with pull down in .IOC  (could this be issue?)Debugger is set to hardware reset, but I have tried all resets. Debugger is set to break at main (not sure if it is trying to break at main without debugger attached?)  I tried to not break at main and will not run with or without debugger.I also put HAL_DELAY(3000); after Hal_init(),  no difference.Here is how my clocks are set: Any suggestions on why it will not run?
