Can someone please clarify if the IN endpoint FIFOx transmit RAM start address part of OTG_DIEPTXFx register should be "word address" or "byte address aligned to 32-bit boundary".We are currently treating this as "word address", inline with what STM32CubeMx does and also libopencm3 USB stack. But, we are having some issues with FIFO corruption and suspect IN endpoint FIFOx transmit RAM start address is not "word address" as it is not explicitly specified as word address anywhere else in reference manual.I have also attached the snapshot of the register description from STM32L476 reference manual can someone please confirm what is correct?

i want implement us delay Delay_us(uint32_t time) function in my application without using timer Hal_Delay() function minimum delay 1ms how can i generate us delay?

What's the difference between Live Expressions and SWV Data Trace? Are they both realtime?Do both of them put a load on MCU processor?Can I use Live Expressions with MCUs which do not provide SWO pin like CortexM0?

Dear ALLI got an problem when i use STM32F429 standby mode.In the first time enter the standby mode it woks fine. I use PA0-WAUP pin to exit the standby mode. But, i make another try to enter the standby mode, it immediate reset。It is seems it entered the mode ok, and immediate exit from the mode. I have no ideal about it.Here is my code to enter the standby mode if(uxBits & BIT_0)  {   UART_PutStr(UART_1,"接收到BIT0被设置的消�?�\r\n");      HAL_PWR_EnableWakeUpPin(PWR_WAKEUP_PIN1);        HAL_PWR_EnterSTANDBYMode();}BYW, i use FreeRtos, and i put the code in a Take with and EverntBit been set

Hi All;I found the problem with 1us. I use this function belowstatic void DelayMicroSeconds(uint32_t uSec) { uint32_t uSecVar = uSec; uSecVar = uSecVar* ((SystemCoreClock/1000000)/3); while(uSecVar--); }I will show result belowMy evolution board for test.In keil use this function at 30uSIn STM32CubeIDE use same function at 30uSAnyone Who can help me about delay in microsecond?Thank you,Best regards.

Suppose I have the following code snippet:void some_func() { int data = GPIOA->IDR; if (data == 0x01) func1(); else if (data == 0x02) func2(); }If optimization is turned on, I would expect the compiler to remove variable data and replace both occurrences of data with GPIOA->IDR -- which is clearly different from the original code.Hence my question if GPIOA->IDR is defined as volatile. And if it is, is this sufficient to prevent this "optimization", or does variable data need to be volatile as well?(My IDE would not jump to the declaration of GPIOA->IDR.)

I noted that when I call HAL_GPIO_DeInit is called (stm32h7xx_hal_gpio.c v1.4.0) the wrong External Interrupt get's de-initialized. After investigating further and comparing to the previous version I noted the following in the external interrupt de-init block: Everywhere the pin mask:0x0FUL << (8U * (position & 0x03U)) appears, it should be changed to: 0x0FUL << (4U * (position & 0x03U))like it was originally.   /*------------------------- EXTI Mode Configuration --------------------*/   /* Clear the External Interrupt or Event for the current IO */   tmp = SYSCFG->EXTICR[position >> 2U];   tmp &= (0x0FUL << (8U * (position & 0x03U))); // <-- Incorrect Here   if (tmp == (GPIO_GET_INDEX(GPIOx) << (8U * (position & 0x03U)))) // <-- Incorrect Here   {    tmp = 0x0FUL << (8U * (position & 0x03U)); // <-- Incorr

Hello! I am starting my activities with the Demonstration Board MB1054A CR95HF and according to what I understand it is only possible to write in a block of 4 bytes, I wonder if there is how to write in only 1 byte?Detail: mine NFC tag is ST25DV04K.Regards, João Pedro, Engineering Student from Brazil.

My question concerns the ZYXDA status bit of STATUS_REG (27h)If I'm reading data out at a significantly lower rate (e.g. 25Hz) than the device is internally generating data (100Hz) is there any need to monitor this status bit?Asked another way, Can I asynchronously read back from the device as long as I'm doing so slower than the device is converting? Or alternatively, is the last conversion buffered?- I'm not at all concerned about data over-runs.The data sheet implies there may be a loss of precision if you don't stay synchronized with the conversion process. I just don't have the resources to poll that data available bit continuously.NOTE: This question and answer originated from a customer support case which was handled by us. We regularly review support cases and add any helpful ones here for all to benefit from.

Hi all, I have been tasked with porting existing Atmel SAMD21 code to an STM32F030xC. I am getting a bit hung up on how to implement the DMA transfer functionality. The existing functionality reads from a SPI SRAM chip, and writes to a SPI LCD display. Both are attached to 2 different SPI peripherals. It is doing this transfer processes via DMA.Now, in the reference manual, it states that DMA can handle peripheral-to-peripheral transfers. If this is the case, how do I setup the Peripheral address register (DMA_CPARx) and the Memory address register (DMA_CMARx)? Do I simply put the SPIx_DR addresses in both registers and just let DMA do its thing? Can DMA even handle this sort of request on the STM32F030xC?Any help is appreciated, Thank you!

We'd like to change something in the ST25RU3993 GUI app but cannot find the source.Only two downloads are listed:SW-ST25RU001 is the GUI binary installerSW-ST25RU003 - sources of firmware.No sources for the GUI.Thanks,-- pa

I am using nucleo-l053r8 and i flash it with S2LP_CLI_NUCLEO_L0 firmware. But when trying to open the port: i always get the message "wrong firmware detected. Please click OK to start upgrade procedure..."I click OK, the firmware is succesfully flashed, but then the popup message is still repeated when trying to open the com port.How can i open the port successfully?I have also flashed the board succesfully over mbed interface and over keil microvision. The pop-up message still remains the same when opening the port.I am using windows 10.  Any help is appreciated.

Hello everyone,I am working on a project on which i would like to send a notification from a board to another when the firts one crosses a threshold with the built-in comparator. I started from the BLE_p2pServer and BLE_p2pClient examples from STM32Cube_FW_WB_V1.0.0 and modified them a bit to fit my needs. Everything was going well until I tried to send a BLE notification from the HAL_COMP_TriggerCallback() in the server. I tried to send the notification with the functions in the server example and then wrote my own functions by drawing my inspiration from the ones in the server example but I had the same problem : the server stopped advertising.I did some researches and found that SCH_SetTask() is responsible, when I comment its line, the server advertises. Do you have any idea on how to solve this problem or just send a simple notification from the server to the client ?Thank you.

Is the USB controller in MP chips same as in F7 (Tensilica) or compatible?Does it support connection of devices thru a full speed hub?Does it support OTG mode?Thanks,Pavel A.

Just got this Nucleo pack, the Nucleo board flash cannot be erased or programmed with CubeProgrammer or EWIAR app. I followed exactly the STM32CubeWB Getting Started Guide - can someone tell me how to program the flash please? Also the USB Dongle is non-fucntional on Win10 - and there is no "inbox" driver that can understand what it is. Do i need to use Win7 to make the USB dongle work? So far out-of-box experience has been totally horrible, not sure how everyone is getting this to work. Thanks

According to the docs I've read maximum FoV using 16x16 SPADs is 27 degrees and minimum FoV using 4x4 SPADs is 15 degrees. But if my math is correct, when side of the measured area is 1/4th then the FoV should be approx. 6.7 degrees. Aren't the SPADs of the same size or is there something else affecting the calculation?

When comparing the data sent from VL53L1X ULD and from VL53L1X_Gui I can see some differences.In particular, I was comparing values sent to registers 0x005e and 0x0061 that are used to configure timing budget. I'm not going to write all measurements here, but e.g. for long distance mode and 50 ms budget the ULD sends 0x00ad and 0x00c6, while GUI sends 0x02f9 and 0x038e. Why such a difference? Which one is correct?Same problem applies to some other registers:0x005b - ULD: 0x08, GUI long: 0x00, GUI short: 0x010x005d - ULD: 0x00, GUI long: 0x00, GUI short: 0x02

Hi, I was evaluating ST25R3911B with 2 evaluation boards: ​X-NUCLEO-NFC05A1 mounted over NUCLEO F401RE and ST25R3911B-DISCO.Regarding X-NUCLEO-NFC05A1 I have uploaded the bin file found in X-CUBE-NFC5 and I have started the terminal as explained in the application note. When I use my ST25TB tags, some of them are recognized and the terminal prints out the UID number, other are not recognized.X-CUBE-NFC5.Regarding the ST25R3911B-DISCO I have uploaded the bin file found in ST website, I launch ST25r3911B Disscovery GUI, I select the polling function, and the program recognize all the ST25TB tags that I use.I do not think it is a matter of antenna, because all the tags are recognized.After debugging the project for IAR found in X-CUBE-NFC5, I have discovered that with the tags not read function rfalSt25tbPollerInitiate returns ERR_FRAMING.So the question is why do the ST25R3911B-DISCO recognizes all the tags while the X-NUCLEO-NFC05A1 does not?Best regards
