Hi, my license for SPC5Studio is expired after 1 year trial. Is there any way to extend this license? I do have a permanent license but it's activated on another Lab PC (connecting to a UDESTK dongle). I need to activate it on my personal PC so that I can create/build and send the program to the target PC. Thanks Bui

Hi guys,I am using and STM32L552ZET6 and I get a behavior I can not exaplain. The device is power at 1.8V in case it matters. So to put it shortly I have 2 blocks of 8 pages each. At first start I erase both of the blocks and write only in block 1 some data. When I get some data to save I write it in block 2 but first I write two doublewords used as markers on top of the first page of block 2 after which I copy most of the data from the first block. My problem is that for the first 24 octets I try to write I get back NSPROGERR and NSPGSERR, and for the rest everything works out great and are written. If I erase the page again just before writeing I get no errors and everything gose perfect.I have tried to debug it by printing the info found in the locations just before programming and I get 0xFFFFFFFFFFFFFFFF in each location with problems.This is the function I use to program:static void FLASH_Program_DoubleWord(uint32_t Address, uint64_t Data){ uint32_t primask_bit; __IO ui

 Hi everyone,i'm trying to use the LPTIM1 in the STM32WB55 on STOP2 mode.I have a STM32WB5MM-DK and I want to generate a PWM on the pc1 output.I configured on the ioc file:LPTIM1- counts internal clock event- checked waveform generation-parameter: prescaler div1 update immediate trigger software output polarity highCLOCK CONFIGURATIONLPTIM1 clock mux on LSE (I tried the LSI with same result)CODE DBG_PRINTF( "*________START PWM______\n\r" ); if (HAL_LPTIM_PWM_Start(&hlptim1, PeriodValue, PulseValue) != HAL_OK) {  Error_Handler(); } DBG_PRINTF( "*________START DELAY______\n\r" ); HAL_Delay(20000); /* ### Enter in Stop mode ########################################### */ DBG_PRINTF( "*________START LP______\n\r" ); HAL_PWREx_EnterSTOP2Mode(PWR_STOPENTRY_WFI); DBG_PRINTF( "*________EXIT LP______\n\r" );So, start the pwm at the right frequencythen wait for 20sbut when the system enter in stop mode, I no longer have the

Hi!I would like to unit test my software, is there any support for that in TouchGFX?Kind regards

Everyone, Posting for the first time here. We've been working with a 4d display that's based on an FT813 IC. The issue that we came to so far is the following.0x7C during Initialization is never detected although, it is detected from MISO. This is read on the logic analyzer. So my thinking is that the FT813 is awake and communicating to the Host.Our setup for FT813 is default : Internal CLK, SPI is at 4Mhz, Pol 0 Pha 1 , STM32 Core Clock is 16Mhz. As I debug the FT813memRead8 function it transmits the REG_ID (0x302000)address however during the SP Receive, we never receive 0x7C. Only when we added an element to return &ftData8[2]; do we receive anything at all. Yet and still it never display's 0x7C that's on the host (MISO). Therefore, we stay stuck at    while (FT813memRead8(REG_ID) != 0x7C) //we should be reading chip ID from C0000 - C0003?    {    }I have personally worked as a firmware engineer contractor for the DOD b

Hello everyone,My variable had a Runover even before it reached its range.Currently, I am working with timer 2 with a frequency of 90MHz. When I retrieved the current time by `__HAL_TIM_GET_COUNTER()` and printed it by `printf("receive_time: %lu\n", (unsigned long)receive_time)`, the maximum the `receive_time` get is 16 bits although I declared it as 32 bits. I observed the printed value and it never exceeded 2^16 -1. I also tried to print with `printf("%" PRIu32 "\n",a);` but it also returned the same. I had another 32-bit variable `send_time` which is used later to subtract with `receive_time`. However, it gave me something in the order of 2*10^9 (2147482170 for example) besides some common values.I want to ask what happen and if I do something wrong. If everything is correct, is there any way to handle the rollover besides having 2 timers starting at different times?The code is here:Radio::radio.tx_buf[0] = seq++; /* set payload */   printf("send a rea

HiCurrently, I'm designing a PCB with "STM32MP151AAD3T".I'm developing our own PCB with reference to "STM32MP157x-EV1".​DDR trace wiring is described in Section 3.2 of "AN5122" as follows:********************************************************************************​Point-to-point connection of the data bus (2 swappable bytes, and swappable bits in the same byte):– 16 data signal bits (DQ)– 2 data mask signals (DQMx)– 2 differential clocks (DQSx_N/DQSx_P)********************************************************************************​What kind of criteria should I apply to swap bits(DQ) in the same byte?Can I prioritize pattern routing?​Best regards,

HiI have a problem where my NUCLEO-U575ZI-Q board gets a hard fault if I use sprintf. I reproduced the error by creating a new project based on the sample project "Tx_Thread_Sync". So I am using Threadx.I then added two lines to the app_threadx.c  char str[80]; sprintf(str, "Value of Pi = %u", 3);And then places a breakpoint at the variable definition. I run the code and when I click on step into the function for debugging the sprintf function the MCU goes directly to HardFault_Handler instead.Please help.What to do so I can use sprintf??Best RegardsAnders

I have STM32CubeIDE installed on a lab machine where internet connectivity is restricted. I need to install v1.27.1. I was able to go to the st.com site and download the en.stm32cubef4_v1-27-0.zip file, transfer it to my lab machine, then using Help->Manage Embedded Software Packages to point at the local ZIP file and install the 1.27.0 main version. However, when I try to install the 1.27.1 patch (en.patch_cubef4_v1-27-1.zip) to upgrade to 1.27.1, the Manage Embedded Software Packages option claims that the zip file is not compatible.It appears that the only way to get the 1.27.1 upgrade is to use the Help->Check for Embedded Software Packages Updates option. But, that requires an internet connection. There does not appear to be a local file selection option. So, now I'm stuck because of the lab's internet restriction.Isn't there a way to get the incremental updates without having to use the internet?

I have a VL6180X that I am running in continuous measurement mode and read from when a hardware interrupt is triggered by the senor. My issue is that I cannot get the sensor to signal at a rate of 100 Hz. Currently, the best I can achieve is 50 Hz.Has anyone had success with this? I have read that tweaking the inter-measurement and max convergence times can help, but I am not sure where to start with those values. Any advice would be greatly appreciated :)Also, within the VL6 API, I noticed that the `VL6180x_RangeSetInterMeasPeriod()` function has the following code block:/* doc in not 100% clear and confusing about the limit practically all value are OK but 0 * that can hang device in continuous mode */   if (InterMeasTime_msec < 10) { InterMeasTime_msec = 10; }This block appears to hard limit the inter-measurement time. Commenting out this check and setting `InterMeasTime_msec=0` helps with reaching 100 Hz, but makes the sensor prone to crashing. Does anyone know why this c

I think there is a bug in the function LL_RTC_WaitForSynchro(). It waits for the RTC_ISR_RSF to become 0 (on row 15). I think this is a bug. It should wait for the RTC_ISR_RSF to become 1 as in the old STM32 Standard Peripheral Libraries. My code sometimes gets stuck in this loop.ErrorStatus LL_RTC_WaitForSynchro(RTC_TypeDef *RTCx) { __IO uint32_t timeout = RTC_SYNCHRO_TIMEOUT; ErrorStatus status = SUCCESS; uint32_t tmp;   /* Check the parameter */ assert_param(IS_RTC_ALL_INSTANCE(RTCx));   /* Clear RSF flag */ LL_RTC_ClearFlag_RS(RTCx);   /* Wait the registers to be synchronised */ tmp = LL_RTC_IsActiveFlag_RS(RTCx); while ((timeout != 0U) && (tmp != 0U)) { if (LL_SYSTICK_IsActiveCounterFlag() == 1U) { timeout--; } tmp = LL_RTC_IsActiveFlag_RS(RTCx); if (timeout == 0U) { status = ERROR; } }   if (status != ERROR) { timeout = RTC_SYNCHRO_TIMEOUT; tmp = LL_RTC_IsActiveFlag_RS(RTCx); while ((timeout != 0U) && (tmp != 1U)) {

Using a STM32F091 board, I set up the ADC to:sample at the longest selectable sampling time (239.5 cycles)clock source is the internal 14 MHz RC oscresolution 12 bitsequence of all available channels incl. vrefintAt startup, there is a slight deviation: I set up the ADC to only sample VERFINT, take a lot of samples and average them; from that, calculate Vdda based on the formula in the reference manual, and store that value in a higher precision format, to calculate all the other voltages with during normal operation of the firmware.Then I set the channel sequence to all channels, as said above.The VREFINT channel is also captured as part of the sequence to, regularly, roughly monitor whether the 3V3 supply voltage is still OK.During operation, when the ADC sequence is being continuously triggered by software, I make the following observations:all channels' values but one stay in their +/- deviation of a few percent from the measured rail's nominal valueonly the VREFINT value has a lot

Hello, I am developing a home appliance application on an MCU STM32G070CB using X-CUBE-CLASSB package and IAR EWARM IDE V8.32.4. I used NUCLEO-G070RB for the early development. The app ran fine until I turned on the SRAM parity check in the options bytes. SRAM parity enabled:The application jumps to the hart fault handler when calling __iar_data_init3 to initialize RAM variables on startup (similar behavior is described here: https://forum.segger.com/index.php/Thread/5957-SOLVED-MEM-MAP-c-error-with-STM32G071/). However, what is worse for me is that the application is not running anymore when the SRAM parity check is disabled (option bytes recovered). SRAM parity disabled: The method STL_StartUp is called from the startup, which performs the startup self-tests including watchdog self-test which performs a reset invoked by each of two watchdogs (two resets overall). However, the MCU is not reset properly and the program instead gets lost somewhere in the system flash memory (0x1FFF 0000

I am using ST25NFC_Embedded_Lib_ST25R3916_1.4.0 on STM32L5 discovery board with X-NUCLEO-NFC06A1And I have no problem to detect and read ST Tag (always correct), but if I use NXP tag I have super strange behavior.On bare-metal application, it works on ST+NXP tag.But on our application that use DMA SPI, and it's 4x slower on CPU I can read st tag but NXP no. He didn't say that he detected anything. From code debug I founded that resolving of NFC conflict always return BUSY and it all. I removed DMA on SPI and still (as the DMA for that short operation give some overhead), but there is a problem. Code is mostly the same, lib is just copied. For me, it looks that this library have a problem on working on more restricted environment. Could you say how to make it working?PS> Before removing DMA I had a problem that protected areas in that lib prevented for getting to interrupt.

I am trying to build an low power application on the STM32WB5M with the discovery kit. There is no PWR example for the DK board or the wb5m, so i am using the PWR_STOP2_RTC example for the wb55nucleo - wb55/wb5m are identical.With measurement on JP5 of the DK i am getting ~330μA for stop2 mode(should be more like 5 μA).When i try the Current measurement with an external power supply (7.2.4 UM2825) and 3,3V the application does not work at all, but there is no more discription for that kind of measurement.What am i doing wrong?

I have followed the video tutorial Getting-Started-X-CUBE-TOF1-sub-titles-burned from the st website on the st website and used the documentation also from the st website Getting started with X-NUCLEO-53L3A2 multi target ranging ToF sensor expansion board based on VL53L3CX for STM32 Nucleo - User manualbut I am unable to get the sensor working. I have used a oscilloscope and have found that no data is flowing on the I2C bus (on either WB board) I have also tried to initialise the other I2C ports but they are also negative. Following the previous instructions I have got the sensor working on the NUCLEO-F401RE board so I am thinking either something is wrong with the physical boards setup (the jumper connections) or the auto generated code needs modifying in some way. I use the STM32CubeIDE to auto generate the basic code that I believe should work as it does with the F401RE board but I have run out of ideas of why it is not working. I have followed the same process for the different chi

Hi,teamCurrently, I'm designing a PCB with "STM32MP151AAD3T".I'm designing our own PCB with reference to "STM32MP157x-EV1".When developing software using this EVM, the connection to PC shown in the attached figure is recommended as following URL.(https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Unpack_the_STM32MP157x-EV1_board)I have questions about the connection with two connectors as follows.Q1. About "ST-LINK/V2-1 Connector"Is it correct to consider that connecting this USB connector to a PC is equivalent to connecting via ST-LINK?For the PCB I'm designing, I want to use a JTAG connector to connect ST-LINK instead of the USB connector.Q2. About "USB OTG Connector"What can I do by connecting the USB OTG connector to a PC?Best regards,

Hello, In the x-nucleo-nfc08a1 reference design, there is the standard 3 variable cap setup (2 series, 1 parallel) plus also a second set of parallel vari-caps (C307 and the oddly named 4C30). But these are not populated on the board. Should we populate these in custom designs? In my design the antenna is a PCB trace coil about 0.75" in diameter but the trace length is about 10 inches and goes through a relay.Thanks,Derek
