Hey everyone,I want an UART communication between my PC and my STM32H745 Disco board. By default the UART 3 (connected to STLINK connector) is one core M4. My baud rate is 115200. My pins are initialized by default. My main is this :and the hal_uart_transmit function returns HAL_OK.On my computer, with Putty, i can't see the data sent. Can you help me with this ? :)  

good morning, I'm trying to import a neural network for NILM (non-intrusive load monitoring) in the stm32 environment, but I can't complete the analysis due to the presence of the error: INTERNAL ERROR: unpack_from requires a buffer of at least 122836864 bytes for unpacking 4 bytes at offset 122836860 (actual buffer size is 1654784) The network is CNN type and I'm working with xcube ai v. 9.0.0 and stm32cubeide 1.15.1I'm asking anyone if they know how I can solve the problem of the buffer size, thanks in advance.

[Basic Info]We're currently having issues with our custom board.It is based on the G431RB in FOC and 3-Shunt mode, with a DRV8323RS as the gate drive and for amplifying and attenuating the current measurement.The motor is a low-inductance (8.1µH) high-power BLDC motor with integrated Hall-sensors.The System is set up as an inverter in 3-Shunt mode, with all three current measurements using one ADC (hardware requirement).MCSDK Version used is 6.2.1, with STM32 FW for the G4 being V1.5.1 (as recommended) in HAL mode.Following tests were performed to verify the proper function of the hardware:- Check of the hardware for shorts and proper voltages- Check of the gate drive signals for correct switching, including dead times (generated by the gate driver)- Check of the current measurement paths, including amplification and conversions inside the library (the current values output by the Motor Pilot properly represent the voltages measured at the shunts)- Check if the actual motor parameters

The BSDL files for STM32H7RS do not contain files for STM32H7RS.Is the JTAG command length the same for STM32H7RS as for other STM32?

Hi ST Micro Team. We are planning to start a pilot project on the use of RFID in our office, We want to to place the tags on the laptops so that whenever an engineer with laptop  exits a room the reader should detect. Could you please suggest a possible RFID  evaluation board /reader with possible tags that can be used. Regards,Karthik 

I built a project in STM32F411E-DISC . project is built successfully and also  when we debugged no issue is found ,but after debugging only ORANGE LED is toggling rest 3 LED is not toggling . kindly help me to resolve this issue .kindly  find for code and microcontroller. 

Hello, using the Ethernet PTP hardware on the STM32H743 processor in slave mode, I synchronize my clock's value and counting speed within the Ethernet peripheral to that of the master device. Is the system clock used by the processor core to execute instructions synchronized with the clock within the Ethernet peripheral? Does the PTP hardware only synchs my clock within the Ethernet peripheral to the master?In other words; Can I synchronize the system clock(not the ethernet clock) of the STM32H743 processor with the clock of the PTP master device on the Ethernet network using the Ethernet PTP hardware? Thanks in advance.

Hi,I never worked with STM32 platform. I have to interface a SDI round display with it.I have seen that TouchGFX includes three "parts": TouchGFX Generator, TouchGFX Designer, TouchGFX Engine. But still not sure what each of them does.A couple of questions if someone could please help:1) What tools do I need to generate the code for the actual custom round display's low level interfacing2) How do I define the round display in TouchGFX? Thank you :)

I have designed my own PCB and I have the problem that while the code uploads successfully, it doesn't run.I have checked NRST and BOOT0 and both should not be the problem. I have found a similar issue where the chip didn't get a clock signal and therefor was stuck. I have used the debugger to step through the code and it went past HAL_Init but I never come past SystemClock_Config, when trying to step into it the debugger throws 'Cannot find bounds of current function'. I am new to designing PCBs and I don't really know where to go from here or what the issue could be.It is not the debugger itself as I can run the blinking sketch with no problems on a dev board that I have bought, which is why I have attached the schematic. I can also provide the PCB layout but I think it is much more likely that I made a basic mistake than that the layout is the culprit.Thank you

 Hi, I had migrated my project from 1.14.1 to 1.15.1.When I change PSC on TIM17 from 0 to 99 on IDE and regenerate the code. The PSC value remains unchanged on tim.c, is this a bug or something I need to configure after migration?This is really annoying that we need to check the parameter one by one to see if the change on IDE is generated to the source code.     Thanks for your help.

Hi Everyone.As mentioned in the subject I have 2 Nucleo F767zit. where i configured one board as Host(CDC) and another as Device(CDC). I referred MOOC USB training(https://www.youtube.com/playlist?list=PLnMKNibPkDnFFRBVD206EfnnHhQZI4Hxa), configured Host by (11.1 VCP Host lab) video and Device by (9.1 and 9.2 VCP)video. Host is sending data which is successfully received by Device(OUT direction communication is working), but when Device sends the Data unable to receive that data on the HOST(IN direction communication is not working). I'm unable debug this. Also tried from (https://controllerstech.com/usb-cdc-device-and-host-in-stm32/) this website still the same problem, Data is not Received by Host , Idk what is the reason can anybody help me out with this. thanks

I'm working with a nucleo 401RE and a x-nucleo ISK 01A3 as hardware and algobuilder and unicleo-GUI as software. If I measure, for example, the rotation vector 9X throughout the day and save the output datalog using Unicleo-GUI, the timestamp shows that every hour and a quarter taking values, there is no data until hour and a half later, also the last timestamp shows that around 48h of data, so there is no data loss, just some weird cyclic jump error on the timestamp.This error doesnt show up on Unicleo-GUI's user messages, just on the .csv timestamp generated.How can i overcome this issue?Any help is appreciated, thanks

So, which is correct and which is wrong?The same is in RM313 for 'F37x.Would those who wrote/modified AN4232 pay more attention to checking the facts through actually writing test cases, rather than applying the "modern feel and look", this must have caught their attention. AN4232 should also mention the dramatic increase in power consumption of the COMP modules in 'G4, compared to 'F3.@Vincent Onde​ - a prime example of why it's in ST's interest of write dozens of appnotes per module, together with concise software examples; instead of just copy/pasting from RM and rephrasing.JW

Hi all,as I'm new to TouchGFX I'm struggeling on a problem hat does not look difficult at first glance.My problem:On screen_1 there is a Text Area allowes the use to enter a string as input.The entered string is needed on screen_2. As far as I know, this has to be done via model files (cpp and hpp).I tried to setup a variable (Unicode::UnicodeChar string_A[10]) in model.hpp but unfortunately I get a compiler error "Unicode....... is not declared.. ) although I have included Unicode.hpp (#include <touchgfx/Unicode.hpp>) in model.hpp.I looked at tutorial 3 which shows me how to get integer values from one screen to another and it works.What am I doing wrong and how can I fix this problem.Thx in advance  

Hello,I use STM32H750XBH6, DataSheet 'Absolute maximum ratings' say that 'Output current sunk by Px_C pins' is 1mAWhat does Px C mean? Does it mean all the pins of GPIOC?Or something else? Thanks!

I'm running the following git source on the NUCLEO-G071RB with NUCLEO-GFX01M2.GitHub - lvgl/lv_port_stm_nucleo_g071rb: LVGL ported to ST's NUCLEO G071RB boardBut, I got an error at the cursor location from the attached figure (LCD Error 1.png).The return value of "data" from st7789v_recv_data function was all 0.I'm not sure this is correct. I guess there should be some values in it.When I run the X-Cube-Display sample program, I got the same error.Please let me know what cause this kind of error.

Hi allI am currently developing a product that uses a TFT display.  The product uses the following:STM32F469ZITxTouchGFX v4.23.2TFT Module 320 x 240, LTDC RGB565 (16 bits), ST7272Very often, when displaying text in a TextArea, some of the initial characters look as though they have been erased, as shown below:The first word should read 'SAFETY'Sometimes, this reads correctly, eg by cycling through my screens and back to this one.All of the other items on the screens such as images, buttons, icons etc display with no problems at all.  It's just the TextAreas that are affected. The font used is Verdana, as supplied in TouchGFX.Any help with this would be most welcome.

I want to generate a code for STM32F767ZI but this MCU is not supported in the STM Motor Control workbench V5.4.8.Available STM32F7 family MCUs in Workbench are STM32F746 and STM32F769. I have generated code for the STM32F746 and flashed that code into STM32F767ZI but it is not working.From some online help, it was found that both MCUs are the same and one can flash the code interchangeably into controllers. Questions:1- Is this possible to flash the code of STM32F746 into STM32F767ZI? If yes, why my code is not working even though I flashed the code into STM32F767ZI, still, I am still unable to build a communication between the Monitor window of Workbench. The COM port is not detecting. 2- if not possible, then should I have to buy a supported microcontroller?Thanks and RegardsNoman

HiI am trying to configure the accelerometer sensor to read the data polling  as the example suggested in githubWhen I try to read /* Read output only if new value is available */lis2dw12_flag_data_ready_get(&dev_ctx, &reg);At initial the drdy will be high after that I am reading the lis2dw12_acceleration_raw_get(&dev_ctx, data_raw_acceleration);  once reading this register the drdy value must be 0 but it is high and its reading this continuously.is there any register I have to check and we have placed this sensor with different MCU and I am new to STM community.Thanks,

Hi all,I have touchgfx project which has many pictures, so I must store them in the SD card.I follow the touchGFX document and I meet some issue.The document said:We can extract the binary data for the bitmaps from the .elf file with a simple objcopy command: $ arm-none-eabi-objcopy.exe --dump-section ExtFlashSection=images.bin TouchGFX/build/bin/target.elf $ ls -l images.bin -rw-r--r-- 1 christef Administrators 147136 Feb 20 11:56 images.bin However, I didn't find the ELF file in the path TouchGFX/build/bin/target.elf; And the MDK IDE can't generate the ELF(replaced by AXF file);When I try to use the AXF file, the command above is returned error(I also try to rename the AXF to ELF):How to split the AXF? Or is there some tools can split the hex file by address?Thanks for your help, have a luck day!
