Hello everyone!I using STM8L050J3 and I wana read UID of DYNAMIC Tag ST25DV04K by I2C. I've read in datasheet of ST25DV04K and saw that: Address I2C of ST25DV04K = 0xA6 or 0xAE.I used those address in my program but I get this bug.Please, Can you explain it for me?Thanks,

Hello everybody,I'm currently using CubeMX + Touchgfx with my Stm32f469i-disco board.Everything works fine, but whenever the board needs to update something that is one first quarter of the screen (e.g updating a text) the whole quarter of the screen reblinks. This doesn't happen when i'm updating something that is otherwhere on the screen.The only strange thing I did was setting manually the hltdc.Init.AccumulatedActiveW and TotalWidth to 202 and 203 (instead of the 802 and 803 created by CubeMX), otherwise the lcd doesn't work properly.Thanks,Mariano

The official release of STM32G4 was scheduled for the 20th week of 2019, but now we are in the 21st week and there is still nothing. Any problems?Andrea

I am using a STM32L476. I am using the counter mode on the low power timer to generate an interrupt after a given period. When I am in run mode, this interrupt works just fine. However, when I use the interrupt to try and wake the MCU from Stop2, I get stuck in the interrupt handler. It seems like the routine to clear the interrupt flags is not working properly. I tried to manually clear the interrupt flags in the IRQHandler instead of calling HAL_LPTIM_IRQHandler but this did not seem to work either. Is this a known issue? Are there any workarounds? I really would like to make use of the LPTIM and Stop modes.

Posted on February 03, 2018 at 07:45I want to calculate CRC for large file, the large file have been added the CRC value in the end of the whole .bin file(Get this CRC data via IAR tool). I read the file and calculate CRC of it in part(HAL_CRC_Calculate(&CrcHandle,  (uint32_t *)data, len).  So I will get lots of crc data because I read it in part.1. How can I deal with these crc data then the final crc vlue will be equal to the one calculated in the IAR?2. Will it be any prolem if the last file part is not divided to 4 bytes(Considered the Byte alignment), then cause the final CRC data is not equal to the one calculated in the IAR? How to deal with this problem?

Hi.I am trying to compile the SBSFU project for STM32L, more exact i am using b-l475e-iot01a.I have put together the following makefile, trying to compile SECoreBin, but i cannot work out how to link it together without getting /usr/lib/gcc/arm-none-eabi/8.2.0/../../../../arm-none-eabi/bin/ld: /usr/lib/gcc/arm-none-eabi/8.2.0/../../../../arm-none-eabi/lib/thumb/v7e-m+fp/softfp/crt0.o: in function `_start': (.text+0x44): undefined reference to `main'Makefile.###################################### # Makefile by CubeMX2Makefile.py ######################################   ###################################### # target ###################################### TARGET = SECoreBin   ###################################### # building variables ###################################### # debug build?

Hi, I was wondering if there is a way to integrate the SBSFU package (as compared to other packages) into the IDE, or more specifically, the CUBE MX, so I get easy configurability inside the Toolchain either than manually changing all my HAL c-files and librarys and so on?My understanding of the whole SBSFU and how to adjust the Framework is still not completely clear because the whole tool lacks significantly in documentation or at least, clear instructions how to use it with different Toolchains/IDEs.

I want to build the wireless application. I see the an5289 is a guide for that. but I can't find where I can download it.

Hi,I really need to know where I can find this application note : AN5289 - Building a Wireless application.This one is mentioned in all yours readme files in the STM32Cube FW WB package but impossible to find it neither on the web, nor through your website.Thanks for reply.

Hello Everyone,I have dealing with STM32F407 I2C peripheral in order to implement Non-blocking communication.I have made many trials but I2C1 event and error interrupts never occur. I checked the SB bits during the debug mode it becomes 1,the other register seems okay but interrupt is never created. Also I have made different trials, changed interrupt priorities, enabled  ev and er interrupts before enabling the periheral, after enabling periheral and after start condition is generated.I have made other trials with cubemx and hal library for my board. After SB bit is set interrupt occured. However  I couldn’t see the start bit  from logic analyzer.What am I missing here ?I am using IAR 8.32, Here is my code ;I2C.c void I2C1_SystemInit(void ){ I2C1->CR1 &= ~I2C_CR1_PE; // I2C peripheral disable // I2C1 Initialization PB8 (SCL) ve PB9 (SDA) RCC->AHB1ENR |= RCC_AHB1ENR_GPIOBEN; // Enable clock for GPIOB GPIOB->AFR[1] |= (4); // PB8 AF4 for I2C1 GPIOB-&gt

Can someone confirm the correct part marking for ST25DV04K-JFR6L3?

Hi, I have installed the latest STM32IDE (V1.0.1) but I cant see how to add the x-cube-ai package. The suggested method is to use the "Help Menu" -> Manage Embedded software packages" but this is greyed out. I also tried using Help->Install new software, I downloaded the "en.x-cube-ai.zip" package and tried to specify it as alocal install, bu this gives errors too.

When I look at source code I can only see bsp driver for ST25r95???It looks like it can detect tag of type ISO14443 or 15693 but the IDs read is not correct and sometimes it is and board reset randomly.My board is NUCLEO-L476RG.

Hi everyone, I'm trying to carry the first tests on our STM32MPU157A-EV1 based board but it automatically turns itself off after 17 seconds, what could be the cause of that?It actually allows me to start the SD card flashing process as stated here in step 6:https://wiki.st.com/stm32mpu/wiki/Getting_started/STM32MP1_boards/STM32MP157x-EV1/Let%27s_start/Populate_the_target_and_boot_the_imageHowever, as it always turns itself off after 17s of being powered, it can never finish the process.Here's a log of the process: ------------------------------------------------------------------- STM32CubeProgrammer v2.1.0 -------------------------------------------------------------------       USB speed : High Speed (480MBit/s) Manuf.

Hi all,I am modifing the Ping Pong example of the I-CUBE-LRWAN; I am working with a L073RZ nucleo board and the SX1272MB2xAS LoRa shield.I was performing some experiment (changing spreading factor, code rate, bandwidth) and the example with SF = 11 and SF = 12 doesn't work on the receiver side.I did not change anything in the example provided by ST: only the spreading factor, which work for SF = 7, 8, 9 and 10.Someone with the same issue?

I used latest CubeMX version and found another one bug in stm32l4xx_ll_usb.c generated by it. If you will compile code using "-O3" optimization level, function USB_WritePMA will not work properly. /** * @brief Copy a buffer from user memory area to packet memory area (PMA) * @param USBx USB peripheral instance register address. * @param pbUsrBuf pointer to user memory area. * @param wPMABufAddr address into PMA. * @param wNBytes: no. of bytes to be copied. * @retval None */   void USB_WritePMA(USB_TypeDef *USBx, uint8_t *pbUsrBuf, uint16_t wPMABufAddr, uint16_t wNBytes) { uint32_t n = ((uint32_t)wNBytes + 1U) >> 1; uint32_t BaseAddr = (uint32_t)USBx; uint32_t i, temp1, temp2; uint16_t *pdwVal; uint8_t *pBuf = pbUsrBuf; pdwVal = (uint16_t *)(BaseAddr + 0x400U + ((uint32_t)wPMABufAddr * PMA_ACCESS));   for (i = n; i != 0U; i--) { temp1 = (uint16_t) * pBuf; pBuf++; temp2 = temp1 | ((uint16_t)((uint16_t) * pBuf << 8)); *pdwVal = (uint16_t)temp2; pd

I'm using the STM32H743ZI with STM32CubeMX and Autollic. with external ADC and DAC with SPI. I have 4 ADC, different CSs, connected to the SPI1 and 1 DAC to SPI2. My DAC works but I get zeros from ADCs. I tested to connected another ADC to SPI3 and disabled SPI1. I saw that when I only used the SPI3, it worked but when I enabled SPI2 (my DAC), SPI3 stopped working. I send some values to my DAC once and read the ADC inside the While(1) loop. SPI1- mood (Recieve only Master) connected to ADCsSPI2- mood( transmit only Master) connected to DAC. I have already checked the spi settings for both ADC and DAC in separate test-board

Dear experts, I'd be grateful if you could point me to some basic CAN bus example code for the F103 (blue pill) which later may be ported to the F4xx family (most likely F423)Thanks for your help!

I am looking at using a few STM32G070 MCUs on a board and would prefer a single programming bus. As they don't have JTAG I am stuck with SWD. I know SWD protocol version 2 allows you to connect SWD in a bus with something called multi-drop. The impression I get is that prior STM32s dont have this but I am hoping it is something that has been added to this new series.

I'm having a problem to make USB CDC device driver work with FreeRTOS. If FreeRTOS is configured without TICKLESS_IDLE mode, USB CDC works fine. However, once TICKLESS_IDLE is enabled (or WFI is executed), I no longer able to finish USB enumeration process. It looks I can't get EP0 interrupt which indicates arrival of incoming SETUP packet. Why?My code is generated by attached CubeMX configs, then main loop is modified to make it sure that FreeRTOS idle task runs.void StartDefaultTask(void const * argument) { /* init code for USB_DEVICE */ MX_USB_DEVICE_Init();   /* USER CODE BEGIN 5 */ HAL_PWREx_EnableUSBVoltageDetector();   /* Infinite loop */ for(;;) { osDelay(10); } /* USER CODE END 5 */ }I have checked RCC_AHB1LPENR settings, but USBOTG clocks are enabled.I also tested similar configuration on STM32F767 and confirmed that USB CDC works with TICKLESS_IDLE mode enabled. That is, I imagine there is a some settings missing specific for H7, but I can't find it.Does

I need to disable Cortex CCR.UNALIGN_TRP bit, but I can't find the proper place in the CubeIDE generated code where this kind of init code should be inserted. Does anyone out there have a clue?
