Hi,The Ram_Shared address in the linker from cubeMx is 0x20008000 but I think it should be 0x20030000.Changing this also fixed communications with cpu2 for me.

HI. Im calling a exe file from CubeIdeit worked fine in true studio but now I get this -@echo in my file name. can anyone tell me what Im doing wrong and how to avoid it

Hello ST25 community I'm working on a research project using ST25R3911B to design the reader. We developed our own antenna and tested power transfer with the ST25R3911 discovery kit. On the other side, I used a STM32L4 nucleo plugged to the nucleo ST25R3911 NFC05A1. At some point, I encountered reading problem. My tag has an energy harvesting chain in parallel to the ST25DV64K (30mW to the charge). With the nucleo kit I was measuring 100% of inventory and read block correct at 3cm, and with the disco kit that distance was more 4 cm. The both kits have exactly the same filter, everything has been measured. The antenna is the same. But the nucleo kit seems to be less performant than the disco kit. I've tried to shield the STM32 on the nucleo but it hasnt really improved anything.At the point, we will do everything with the disco kit which meet our requirements (which is not the best as it misses lots of outputs on the MCU - no spare SPI or IOs).We don't understand why the nucleo kit isn'

Hi All,I have created a new ST32IDE/ST32MX project for controller STM32G473CET6-01 at my own PCB.USART, CRC and FREERTOS is added .This project compiles fine, but the moment i press the debug button ,it goes straight to void HardFault_Handler(void) ?This happens without pressing the Resume(F8) button after debugger is loaded.Wondering why this happen? As STM is new for me , i hope to get an easyer asnwer then "search the hardware fault", i didn't expect this problem with an empty project . :grinning_face_with_sweat: The first thing i wanted to try do is remove RTOS, but it seems that not possible, do i need to create a new project in that case?Thank you ! 

I am using STM32F302R8, and have setup channels 1 to 5 of TIMER1 in various output modes. In the callback function, I would like to identify which channel generated the interrupt.I am using HAL, and can figure out which timer generated the interrupt, like so:void HAL_TIM_PeriodElapsedCallback(TIM_HandleTypeDef* htim){ if (htim->Instance == htim1.Instance) { go_do_stuff_for_timer1();}else if (htim->Instance == htim2.Instance) { go_do_stuff_for_timer2();}}But, how to tell which channel of htim1 generated the interrupt?

I am working with an STM32WB5MMG, but I don't think this issue relates to the radio part of the MCU, so I am posting in the more general community. I hope that's okay.I am reading data from a GPS receiver over UART using the HAL_UART_Receive_DMA function. Data is coming in at 230400 baud. DMA is configured as a simple (non-circular) buffer of 512 bytes. In the HAL_UART_RxCpltCallback handler, I call HAL_UART_Receive_DMA again to start a new transfer.I'm doing it this way (as opposed to using circular mode) so that I can count the total number of bytes transferred by counting the number of complete "frames" of 512 bytes and adding (512 - CNDTR). My concern is that if I used a circular buffer, there is some ambiguity about when the frame count is updated relative to the CNDTR update.Usually, this works fine. But after a couple of minutes of receiving data, it looks like CNDTR stops updating. I've checked that there is still data coming in from the GPS module. What's curious is that when

Hello, I am using a STM32F401CE and would like to use the independent watchdog to cause a reset if the device would lock up for some reason. I have an external chip which is being controlled via GPIO and SPI from the STM32F401. When a watchdog reset occurs, does the GPIO outputs all default to Off? Is there I could keep an I/O line high (SET) over a Watchdog reset? I would like to not reset the external device if a watchdog event occurred. Thanks. Josh

I'm using ST25 android sdk. When sending data to nfc chip it sometimes fails to write data. I can send 4 bytes with any content.When sending 10 bytes then it fails with TAG_NOT_IN_FIELD depending on data.This one succeeds: byte[] data = new byte[10]; data[ 0 ] = 0; data[ 1 ] = 'A'; mTag.writeMailboxMessage( 10, data );   2021-01-31 13:03:39.123 32184-32259/eu.fufla.nfccomm D/Iso15693CustomCommand: ==> Send writeMsg command: 22 aa 02 85 66 df f3 00 24 02 e0 09 00 41 00 00 00 00 00 00 00 00 2021-01-31 13:03:39.125 380-15695/?

Please explain the purpose of 4 Parallel MOSFET, Why we cant use 1 or 2 MOSFET with higher rating, Also Why three seperate MOSFET driver is used for each phases, Why single Driver with 3 Channel is not used. Whether it can be used, Please suggest any advantage of using as per yhis design.

I use CubeMX to configure my timer 2 to use Encoder Mode: "Encoder Mode TI1 and TI2". In my code should I use HAL_TIM_Encoder_Start(&htim2, TIM_CHANNEL_1)orHAL_TIM_Encoder_Start(&htim2, TIM_CHANNEL_2)orHAL_TIM_Encoder_Start(&htim2, TIM_CHANNEL_ALL)or something else?P.S. What means TI1?

I am checking the difference between LSM6DSMUSTR and LSM6DSMTR. Distributer Mouser has both of them. But the data sheets are the same. Thanks,

Dear all,I used STMStudio until today to watch multiples values in real time.Today i want to use STM32CubeMonitor and it seems a very interesting tool.However i don't find a quick way to visualize multiple variables values in a array like STMstudio allowed it.The only solution i found today is to get my variables, then perform a switch to get only one variable and disply each variable with a text : My text node content to display the variable and its value is : Is there a better way ? Indeed, with this solution, if i have to display 50 variables i need to put 50 text nodes on my page.With STMStudio it was really easier. I think there is a better solution i don't know.Best regards,

The 'Debug' Build Configuration in the B-072Z-LRWAN1 Ping-Pong example does not define the DEBUG symbol.This means that you cannot debug the DEBUG configuration!Who on earth thought that was a good idea?!:persevering_face:If you do want to debug, you must add 'DEBUG' to the list of preprocessor defined symbols in Project Properties: See also: https://community.st.com/s/question/0D50X00009bNTmPSAW/pingpong-example-from-icubelrwan-software-not-working-on-bl072zlrwan1 - 3 years ago!

I'm working on a bootloader which needs to erase and program the Flash. The erase seems to be 'working' but I have a suspicion that I'm not waiting long enough for the 'Busy' bit to go active after setting the 'Start' bit. The reference manual says I need to poll for 'Busy' to go active in the pseudo code, but leaves it to the user to code a timeout. Can anyone give me the timings for the Flash status register as I can't find it in the data sheet?

Hi,I'm having an issue which I can't seem to resolve:I'm trying to change the output value of Pin9 (Port C) through an interrupt routine (TIM3).If I put a simple XOR statement for this pin in the interrupt routine it works as expected.However if I try to load in values from an array the output starts to become inconsistent. This is best seen in the attached screenshots from the oscilloscope.I have checked in debug mode how many cycles there are between writes to the pin which is pretty consistent for both (40 for xor, 70 for array load). Why is there then a difference between the length of the two 1's (see screenshot array-output).Code: https://github.com/maksimdrachov/yada-brussels

Good evening to you all electronics dark wizards.To the point:I am interested in flashing specific pages of stm32 chips because im locating some custom binary config files for my application.I found the option in my stm32cubeprogrammer v2.6.0 to define the Start Address but the data input box cannot be used for some reason?

Hi, i need to measure rms voltage and current choosing ADC channels in stm32f103.i selected two channnels in ADC1 to read adc values . By using these channels i need to calculate rms voltage and current . But i am confused how to do it . is it necessary to do calibration also. can anyone help me how to write a code or how to start it please.Thank you

Hello. I'm currently working on a RFID research project using 2 ST RFID chip : ST25R3911B and ST25DV64K. The reader is the discovery kit with a home-made antenna to suit to the project constraint. The external filter has been redesigned and transferred power to the tag is all good. The tag is based on the ST25DV64K plugged to a specific antenna as well. There's a parallel circuit that provides power (harvesting with diodes) to a MCU and sensors. The energy harvesting feature of the ST25DV wasn't enough for our needs. Even without consumming power on the tag (only the RFID chip and diodes bride), i can't manage to suceed a FAst Read BLock command. I have 50% of error i'd say. Normal read work well, even with a 30 mW consumption after the diode bridge. But I can't manage to make the fast mode working. I've tried to change filters parameters (register in the ST25R3911) but no success. Could it be the specific antenna bandwidth ?Is there any tricks in the ST25R3911B to achieve fast mode ?

I am using NUCLEO-L010RB.When operating RTC (standby mode) using LSE,What is the current consumption during RTC?

HI, i am using TB6600HG stepper IC in my board to drive stepper motor using stm32f103R8Tx. In TB6600hg driver IC there is a Alert Pin its function is to monitor TSD and ISD.where TSD is built in thermal shutdown.ISD is built in overcurrent detection.if my TSD = Under TSD detection and ISD=normal then ALERT = low.if my TSD= normal and ISD= normal then my ALERT = z. And even they are used 'z' for some other pins to check the state.But I don't know what that 'z' refers or meaning in TB6600HG driver IC . can anyone help me with it please.Thank you

Hi all,This post is obviously coming from a person without any USB development experience.We use some off-the-shelf instruments which I know to be based on STM32, and they connect to a PC using the Virtual COMPort. Nothing new here, the standard Windows drivers perfectly recognizes it and I can communicate using any console program.What we would like to do is to get rid of the PC: make an external "controller" device with another STM32 with USB OTG to which the instrument would be connected (a small LCD and a few buttons will be the interface to whatever the instrument requires). Our controller would recognize the VCP, and "convert it back" to a serial transport layer.So I guess we are looking for the C/C++ "reverse" of the VCP driver.[STM32_INSTRUMENT]-------->(USB_CABLE)-------->[STM32_USB_OTG][SERIAL_DATA]Does anyone know if there is such a thing available?Thanks,Bruno

Hi guys,I'm a little confused about the trigger voltage for rising-falling triggered interrupts. As my previous understanding, the trigger voltage should be Vih and Vil. But some one told me Vih and Vil is not for edge triggered interrupts. The thing is, when I observe the waveform with a Oscilloscope along with an interrupt counter from Keil, I did see the interrupt happened when the voltage did not reach the Vih(rising edge). I use 3.3V voltage. The signal is only 1V around and the interrupts was triggered. I checked the manual of STM32 and did not find the answer.Could some one help?Thanks,

I need the callback, to clear the cb4.DMA_Active flag and update a pointer when it finishes. I cannot step through it because it starts sending data over and over as I step through it and does not call the callback. First time msg points to "1234567890\r\n" len = strlen(msg)Second time msg points to "ABCDEFGHIJKLMNOPQRSTUVWXYZ\r\n", len= strlen(mssg)Second time it sends "1234567890\r\n" again. static void dma_debug_write(char *msg, size_t len){   // this is the real code I want to run.   cb4.DMA_Active = 1;   huart4.Instance->CR3 |= USART_CR3_DMAT;   HAL_DMA_Start_IT(&hdma_uart4_tx,               (uint32_t)msg,                (uint32_t)&huart4.               Instance->TDR,  &nb
