Solved

HiI wrote a little CEC application. Unfortunatly communication with other devices didn't work well.I used a logic analyzer to find the problem.The error is in the IRQ function HAL_CEC_IRQHandler:[...] if((reg & CEC_FLAG_TXBR) != RESET)  {   if (hcec->TxXferCount == 0U)   {     /* if this is the last byte transmission, set TX End of Message (TXEOM) bit */     __HAL_CEC_LAST_BYTE_TX_SET(hcec);     hcec->Instance->TXDR = *hcec->pTxBuffPtr++;   }   else   {        hcec->Instance->TXDR = *hcec->pTxBuffPtr++;     hcec->TxXferCount--;   }    /* clear Tx-Byte request flag */   __HAL_CEC_CLEAR_FLAG(hcec,CEC_FLAG_TXBR);  } [...]The error is in line    if (hcec->TxXferCount ==

Hi guys i am trying to find alternate function map to AF0,AF1 and so on but i did not find that in datasheet where is that i am using stm32f303re from nucleo-64.

My daily use IDE is Atollic, my board used to have a single 6 pin connector for programming, and everythin worked fine since I can remember.The new hardware guy decided to add another connector to program the MCU (STM32F4), and our new board ended up like this:He also insisted that we should use the 4 pin connector, and promptly made new cables for everybody in the team. Despite being identical and respnding normally to the meter continuity test, some of the cables worked and others didn't.My cable worked for almost one week, but after some time I started receiving script error messages from the IDE. Apparently, it was unable to verify the flash.I tried to use my old 6 pin cable, but it seemed that my programmer was gone. As I'm the only developer (the other guys only have to make occasional updates), I started borrowing their gear.In a matter of hours, all the programmers I had borrowed were gone. They didn't work with Atollic, neither with STM32 Cube Programmer. The hardware guy said

Posted on September 21, 2017 at 16:11As we know,RFID has a big market.But we only use R2000 by Impinj to develop new reader.The R2000 is not open source system.So we need a new chip to instead of it. So when do we use the demo of ST25RU3993 or other UHF reader chip by st team?We also need the code in the local.

Posted on April 29, 2018 at 16:25Hi,As though there are libraries available for Mac OS X, my simple application randomly (almost always) crashes, and it has something to do with the dynamic libraries provided, specifically streader.dylib.Any thoughts would be appreciated.I'm running a MacBook Pro with macOS High Sierra version 10.13.4.My code:public static void main(String[] args) throws STException { stReader = new STReader(); boolean connected = stReader.connect(); connected = stReader.connect(); RFGenericReader mActiveRFReader = stReader;        if (connected) {        System.out.println('Connected!');                 String name = mActiveRFReader.getName();        System.out.println(name + ' is connected');                 stReader.initialize();        List<byte[]> uidList = new ArrayList<>

Тhe document  «UM2268 User manual ST25RU3993-EVAL board software» describes the graphical user interface software (STSW-ST25RU001) for the ST25RU3993-EVAL board.  In the Reader Settings window of STSW-ST25RU001 be present Frequencies panel with possibility selection Profile frequency band (for different regulatory regions). However, in product version 1.5.6.0, this option is absent.

I cannot find the corresponding pins on MCU to the I2C Grove connector located on the fanout board. Currently I have an acceleromater connected to the Grove connector and would like to collect data from that. I have tried to open a new CubeMX project but cannot find the STM32L4R9I-DISCO board. I only see the STM32L4R9I-EVAL board. Please help.

Posted on March 21, 2018 at 13:27Hello there,I am using the STM32L4 family MCU. In my hardware design, only after the USB cable is connected the voltage is applied to the VDD_USB pin of the MCU. At no USB connection this voltage is not present.As a follow-up to this discussion, I am trying to configure everything now: https://community.st.com/0D50X00009XkhQCSAZ My problem consists of 2 sub-problems: I cannot get the PVM1 (EXTI35) interrupts to work.I dont know what is the PVM1 wakeup time.The procedure described in the datasheet is as follows:What I do is the following: I enable the PVM1 interrupt:In the generated code I see it is enabled:/**  * Initializes the Global MSP.  */void HAL_MspInit(void){  /* USER CODE BEGIN MspInit 0 */  /* USER CODE END MspInit 0 */  __HAL_RCC_SYSCFG_CLK_ENABLE();  __HAL_RCC_PWR_CLK_ENABLE();  HAL_NVIC_SetPriorityGrouping(NVIC_PRIORITYGROUP_4);  /* System interrupt init*/  /* MemoryManagement_IRQn interrup

Can we avoid the ADC and DMA transfer interrupts and check a status of DMA transfer done for new values converted by ADC with multiple channels?My MCU is : STM32L1

Datasheet says these readers support ISO/IEC 15693 standard for vicinity cards. I need a system with high reliability (99%) read for distances up to 1 meter (0.5-0.7 m as the most probable range). Can I use this IC for building such reader alone, or I need additional RF components? What size the antenna should be?Also, what kind of tags will work best? I can make powered tag as well, but I need min 6 month battery life on something like CR2032.

1 The code was generated by STMCube and the MCU is stm32f030k6t62 I use 8M HSI RC as clock source .3 If I set SYSCLK to 8M (use HSI RC directly), the code can work on the board correctly 4 if I set SYSCLK to 48M (use PLLMUL). the code didn't work at all . 5 I just toggle a LED based on the generated code . 6 why did we can't use PLLMUL with STMCube?

Hello,I enter the shutdown mode with the following code statementHAL_PWR_EnableWakeUpPin( PWR_WAKEUP_PIN1_LOW ); HAL_PWR_DisableWakeUpPin( PWR_WAKEUP_PIN2 ); HAL_PWR_DisableWakeUpPin( PWR_WAKEUP_PIN3 ); HAL_PWR_DisableWakeUpPin( PWR_WAKEUP_PIN4 ); HAL_PWR_DisableWakeUpPin( PWR_WAKEUP_PIN5 );   __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF1); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF2); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF3); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF4); __HAL_PWR_CLEAR_FLAG(PWR_FLAG_WUF5); HAL_PWREx_DisableInternalWakeUpLine();   HAL_PWREx_EnterSHUTDOWNMode( );If I wake up the system with PWR_WAKEUP_PIN1, I set the GPIO15 from PORTH to high.I initialized the PORT and GPIO (CubeMX generates the code).The result is that the system is hanging. If I reset the GPIO to low before entering the shutdown mode, everything is working fine.Am I missing something? Maybe someone can explain me if I doing something wrong.Is there any bug know that happens when using shutdownMode on STM32L4+ series?Thanks.

Hey everyone,I have an stm32f722ze, The sdcard driver seems to be working well although I have a weird issue.I have a secondary mcu that also needs to access the sdcard.The secondary mcu can succesfully mount and unmount the sdcard multiple times, although as soon as the stm mounts the sdcard, the secondary mcu can not mount the sdcard at all. I do close the file, unmount and unlink the driver, but it doesn't seem to work. As soon as I erase the flash of the stm, the secondary mcu access the sdcard without issue. How could I resolve this?Here's an example of a test snippet, after this executes, I'm assuming that the stm has left the sdcard, although it seems the stm seems to hold onto it.void SDcard(void) { FATFS_UnLinkDriver(SDPath); FATFS_LinkDriver(&SD_Driver, SDPath); mount_ret = f_mount(&SDFatFS, SDPath, 1); if (mount_ret == FR_OK) { open_ret = f_open(&SDFile, "test.txt", FA_CREATE_ALWAYS | FA_WRITE); f_close(&SDFile); umount_ret = f_mount(&SDFatFS, S

Hi all,I have a custom board I have designed with an STM32F070CBT6 on it. Currently it is only populated with the power regulator, one led hooked up to pin PA1 and the debug header.I've used STM32CubeMX to generate a simple test project that initialises the SysTick timebase source, and GPIO on pin PA1. It is clocked using the internal HSI RC oscillator at 8Mhz.When I build and debug the project using SW4STM32 the debugger steps over HAL_Init(), SystemClock_Config(), and MX_GPIO_Init() successfully, but hangs shortly after that. E.g. if I put the following in the main() while loop: while (1) { HAL_GPIO_TogglePin(STATUS_LED_GPIO_Port, STATUS_LED_Pin); HAL_Delay(500); }It will step over the call to HAL_GPIO_TogglePin succesfully turning on the LED, but then hangs at HAL_Delay(500);If I put a breakpoint in the SysTick_Handler(void) function in stm32f0xx_it.c it never gets hit. It appears like the interrupts aren't firing.I've attached my CubeMX project file in case that is of hel

In all of my projects I have my own bootloader which is located at 0x8000000 and is specially designed to communicate with my own Windows universal Flasher-Tool. My bootloader initializes necessary components for the needed communication ports (e.g. USB) and looks into a defined flash address (0x08020000) for a start address of the final application. This is flashed by the bootloader after the final application has been loaded to the application sectors (0x08080000 in this case). If a correct address is read, then the bootloader deactivates Interrupts, unitializes components and jumps to the start-address + 4.This handling works perfectly on my multiple other projects with STM32F4 and STM32F7 processors.Now with the STM32H7 this does not work. The system simply crashes after the jump to 0x8080000 + 4.I took care that the interrupt vectors are linked to the correct offset, have set SCB->VTOR to the offset 0x80000 and when I compare the flash memory with the hex file, all looks as exp

Hello, I am using STM32Cube_FW_F4_V1.21.0 library version.I would like to implement USB mass storage device example along with SDIO interface. When I connect my STM32 device with the PC, I wish to see my SD card content on my PC.I made some configuration in the cubemx. However it is not working.Could someone share a working copy ?Do I need to modify the content of the "usbd_storage_if.c" file ?

I'm a beginner. I'd appreciate your help.

When I compile and download the code. I see a USB problem.What could be the possible solution ?

Hi Everyone,I am Using the L6MSDL chip for my application (connected to a STM32L4) in FIFO Continuous Mode and I am having some troubles understanding the FIFO pattern that we can read in FIFO_STATUS3 register. I configured the LSM6DSL The following way :-         Accelerometer ODR = Gyroscope ODR = FIFO ODR = 413 Hz-         No decimation-         Only accelerometer and gyroscope data sets are stored in fifo-         BDU Block Update is enabled-         FIFO Is in continuous modeI read periodically what is stored in FIFO. To know how much data is stored, I read the FIFO_STATUS1 and FIFO_STATUS2 registers. I make sure to read a multiple of 6 data sets each time (3 gyroscope data and 3 accelerometer data)I read fast enough so no data is overwritt

hey there,I bought me STM32 ST NUCLEO-L432KC for getting more into ProgrammingMicrocontrollers.In School i have already Programmed an ARM Coretex M3 Development board.There i had a Manualwith descriptions of the Controllers Registers, and how they are to use.I searched for such kind of document for the Nucleo L432KC but didn’tfound anything witch helped me.So now I’m a little bitt confused.Is there existing anything like this, or is it common to Initialize themodules with the help of CubeMX and only using the Functions of the core libraries?or maybe I’m just to stupid to understand the documents I have found :P.

Posted on January 15, 2017 at 23:06Hello I am reporting a bug generated by cubemx in the file stm32f4xx_hal_sd.c.Please read the thread: https://community.st.com/0D50X00009XkfctSAB , https://community.st.com/0D50X00009XkeRpSAJ Here is the thing:1. Pack version: STM32Cube_FW_F4_V1.13.0, Cubemx 4.16.1. The uSD card I tested is 1GB made in japan.2. The lib for microSD and file is generated by cubemx wizard.3. I tested the microSD on the chip STM32F405RGT6 . . 4. The problem I confronted is that initialization of sd card always fails, but everything goes through smoothly if I reset the chip(via nrst). Weird? Make the story short. Initialization of SD card fails in the function: SD_PowerON(SD_HandleTypeDef *hsd) with error code SD_COM_CRC_FAILED. Note the function is defined in the file: stm32f4xx_hal_sd.c5. I moved the HAL_Delay(1) to after clock_enable in the function SD_PowerON , everything is working well.I am not su

Usually with STM32 development boards I am able to see a virtual com port/serial port when I hook the board up to a computer via USB. This board, the F0308-DISCO, seems to have the TX/RX pair for UART communication between the target MCU and the ST-LINK MCU, but no such port is visible on the computer. I am using macOS and have updated the debug probe to it's newest firmware version using the STM32CubeProgrammer tool. Is there a special driver needed for this board (seems unlikely as the boards seem to have a common implementation of the ST-LINK probe), or some other reason why the VCP will not show up? I have come to rely on this functionality quite a bit in my development process, as the semihosting print capability is extremely slow. Thanks in advance.
