Hi, I'm starting to work with a Nucleo-64 with a STM32F072RBT6.I'm reading these documents and not really understandign them:https://www.st.com/content/ccc/resource/technical/document/user_manual/2f/77/25/0f/5c/38/48/80/DM00122015.pdf/files/DM00122015.pdf/jcr:content/translations/en.DM00122015.pdfhttps://www.st.com/resource/en/datasheet/stm32f072c8.pdf I configured the Timer1 correctly. I start it with these lines of code : HAL_TIM_PWM_Start_IT(&htim1, TIM_CHANNEL_1); //Start the channel in interrupt mode HAL_TIM_PWM_Start(&htim1, TIM_CHANNEL_4); //Start this channel with no interruptI tested with a scope that these few lines work: while (1) {  /* USER CODE END WHILE */  HAL_Delay(1000);  TIM1->CCR4 = 1500;  TIM1->CCR1 = 1500;  HAL_Delay(1000);  TIM1->CCR4 = 500;  TIM1->CCR1 = 500;  /* USER CODE BEGIN 3 */ }My question is how (what syntax ) do I write the code I want to put in the interrupt r

Hi there,I've downloaded the SPC5-CRYP-LIB from the ST website. It says that it should be supported for the whole SPC5xx family, with hardware support only enabled for the SPC560B/C MCU. I am trying to import this plugin for the SPC560B54, but SPCStudio is saying it is incompatible with my project. When I try to import it anyway, it fails to compile. Is there anything I'm doing wrong here?

Posted on August 03, 2017 at 09:53Hi ! I'm currently looking for the best sleep mode for my device.I'm not able to find any information on Datasheets or Application Notes on the capability of wake-up a STM32L476RG via USB Bus on the Shutdown Mode.I know that we can do this wake up in Stop 0/1 Mode, but the shutdown mode would be perfect for me as I only need 5 GPIOs + USB to wake-up my device.Do you have any information about this ? Do you know if i can or cannot wake-up my STM32L476RG with USB during the Shutdown mode ?Thanks you for reading me.#shutdown-mode #usb-wake-up #stm32l476rg #stm32l4-usb

Says in the title, where can i find the flag to remove warnings treated as errors

Hello, I'm trying to evaluate the STM32MP1 using a STM32MP157C-DK2. I followed this getting started guide and successfully flashed the board, even though the archive downloaded has a slightly different name than mentioned in the guide. I set the boot switches to the on position and reset the board, which is showing the UBoot splash screen. But afterwards it goes dark, no Linux splash screen, Weston desktop or GTK demo launcher to be seen anywhere. The system itselfs seems to work correctly, as pressing the reset button with minicom connect shows (see log attached).The big LED next to the ST-LINK is constantly red. A small LED close by flashes two times blue, then pauses, followed by another two flashes...What am I missing here? Shouldn't the board boot to the GTK demo launcher automatically? Best Regards,Matt

Hi, I'm evaluating the STM8 UART emulation library (STSW-STM8051). I'm using the STM8SVLDISCOVERY board. Instead of the TIM3 I'm using the TIM2 timer since the TIM3 is not available on the STM8S003K3: I configured the project to communicate at a baudrate of 19200bps 8N1. The library uses both UPDATE and CAPTURE/COMPARE interrupts from the same timer. It seems that if the two interrupt flags are set in the same time only one ISR is serviced; it seems that only one interrupt from the same peripheral is serviced while the second one is not kept in queue. I have tried also with different priorities without success. The problem seems to arise if the second interrupt flag is set while the first ISR is evaluating the TIMx->SR1 register and clearing the flag (therefore if the compare register value is near the autoreload value).In the errata this issue is not described. Can you please tell me what can I do to solve the problem? This problem must be solved to allow for full-duplex communicat

Hello,In secured boot getting started it is said:"Download the SB SFU project software to the target without starting a debug session(Security protections managed by SBSFU forbid JTAG connection as it is interpreted as anexternal attack)"Does it mean it should be done using IAR: Project->Download->Downloading File ?Isn't it still using JTAG even if it is not yet debug ?Thanks,ranran

I am using an STM32F303CB with HAL/LL version 1.10.0It seems that TIM2 is not available in the drivers for this part as RCC_CFGR3_TIM2SW is not defined.Is this a fault with the driver library or a configuration from Cube?Thanks

Hi,I use a STM32L052 and I would like to use DAC as VREF for comparator 2 (PB6) but without connecting DAC1 to PA4. It is possible ?Because under STMCubeMX, when I set DAC as VREF for COMP2, it set automatically PA4 as DAC_OUT1 but in my application, PA4 is used for something else.So is it possible to set DAC1 as VREF for COMP2 only in intern ?

I'm having trouble understanding this from the datasheet and reference.What peripherals are allowable targets for DMA1 memory-to-peripheral transfers?Thanks, Best Regards, DavePS: I tried to use a stream in DMA1 to write to a DMA control register, and it fails...

Hi, is ST planning to release new version of the X-NUCLEO-IKS01A2 sensor expansion board with the newest recently released sensors? I would like to interface LSM6DSO with NUCLEO-L4. Tks

Has anyone implemented their own firm ware. I can so far successfully retrieve the EPC number from a tag, however I'm struggling to get a valid RN16 and CRC combination when using the REQ_RN command. I would like to do this to be able to access the TID memory.

I have successfully read an epc tag, my next step is to issue the the Req_RN command. I hav set the RX lenthg register ready to receive 4 bytes of data and issue the Req_RN command. OIn the occasion that I do receive the expected 4 bytes of data they never seem to be a matching RN and CRC16. Can any one help?

I can see in the example firmware that the TID memory is read in multiple stages, with the first 8 bytes read first. In my application I need only these first 8 bytes, so following a very similar process I can read these bytes. I am working with a CRC on reception. So I am expecting to receive 12 bytes comprising of the first 8 bytes of TID memory (which I do receive) + 2 bytes of indicating the tag Handle, which I also receive and finally two bytes of CRC, however when running a Genibus check the CRC fails. Am I incorrect in what I am expecting from the read TID memory command? Would the CRC only be returned after a complete read of the TID memory? The actual hex codes are shown below. On completion I receive: 0xE2 0x00 0x38 0x11 0x60 0x00 0x60 0x15 0x31 0x1f 0xF0 0x3Awhich when checking with https://crccalc.com/ would return 0xc3 0x50 using Genibus.

Hi, Want to be able to flash the target device( an STM32F446) using a propritary CAN interface. EI not use the bootloader default CAN flashing method. As i understand it I must first make a IAP binary and flash using the bootloader by SWD. To then add the application I MUST use the IAP interface over CAN. Is this correct? Or is there a method to flash both IAP and application over SWD at the same time? And have them both in the same project in Atollic? Also can I do a adress jump to the IAP from the application? Hope anyone can give me some pointers.

Everywhere else (both in this DS and RM0090 rev.17) it's PIXCLK.(In an older CubeMX it was wrong, too, but I don't use CubeMX so won't download current to check).JW

Hello community, I have a little doubt. Are all the GND pins internally connected inside the microcontroller? Is the analog reference (AVSS) internally connected with the digital one (VSS)? If it not, how is the isolation between them?I don't know where I can do the union between the analog AGND plane and the digital GND plane and I was thinking if I can use the microcontroller to perform internally the connection. Thank you in advance!Luis

Hello everyone,I'm tring to implement a calculation of firmware CRC in run time mode.Is there inker command method to acquire last address where code is written?I'm quite confident there is a specific command like __text_end__, for example.Best regrds

I changed linker to use all of these three memories in domain D2. Problem is next :When i put for example uint32_t tempArray[4] = {0x2B7E1516 ,0x28AED2A6 ,0xABF71588 ,0x09CF4F3C} __attribute__((section(".sram1")));this line in my code, when MCU is in debug mode firstly on address of this array i see all zeroes. After calling __HAL_RCC_TIM2_CLK_ENABLE() macro, i can see data in those sram's but it is wrong initialized (random data).Am I missing something? I read thru all documents RF, DS, AN's but neither one says that this memory is something specific. I used this part's of memory as DMA buffers for SDMMC2 and everything is working fine. Only problem is in initialized data.I tried same code - just changed section to AXISRAM and everything is working as expected. So not problem in code.Thanks

I am trying to deploy a pre-trained Mobilenet model using STMCubeMX.ai, but I am facing some issue that I want to report.Here the link of the projecthttps://github.com/alessandrocapotondi/mobilenet_stmcube_aiHere the model I am using:https://github.com/alessandrocapotondi/mobilenet_stmcube_ai/blob/master/keras_model/mobilenet_160_0_25.h5Here the resource usage of my model:600KB RAM for the activations and 1.79MB of weights. Unfortunally despite the "Green Light" given by the tool for the deployment on the STMH7432ZI on the device there is no segment that can fit such ammont of contigous data./* Specify the memory areas */ MEMORY { DTCMRAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K RAM_D1 (xrw) : ORIGIN = 0x24000000, LENGTH = 512K RAM_D2 (xrw) : ORIGIN = 0x30000000, LENGTH = 288K RAM_D3 (xrw) : ORIGIN = 0x38000000, LENGTH = 64K ITCMRAM (xrw) : ORIGIN = 0x00000000, LENGTH = 64K FLASH (rx) : ORIGIN = 0x8000000, LENGTH = 2048K }Best,Alessandro

Hey,According to the datasheet, the stm32f103RB has 128K of Flash memory. If my code exceed 64k I am getting a linker error “L6406E: No space in execution regions with .ANY selector matching …�?Did I have overlooked something ?I'm working wth the Keil IDE.IDE-Version: µVision V5.10.0.2Best regardsGoran

READ/WRITE operation using the data/value blocks will require a manual key load to the smart card reader and then use that key to authenticate a certain sector or block based on the usage of the developed code.Is there authenticate and load keys functions supported by this device?i am using M24SR64-YSDK NFC1 version 1.8

I am trying to program the STM32H753 flash on our board in DFU mode. Specifically on a raspberry pi running linux.I connect the boot0 to 1.8V while plugging in my USB-C cable and then the boot0 jumper wires are no longer connected. So if DFU mode is exited, I expect the application to run and for blinky leds to reflect that.In Windows, using DeFuSeDemo, I can program the flash and then click the button "Leave DFU" and see that the application was started based on LEDs that blink.However, I can't seem to figure out the right application and syntax to program the flash from the command line with the option to leave DFU after. I'm starting to think this isn't a syntax/application issue, but maybe a board/firmware issue.In windows, the DfuSeCommand.exe doesn't appear to have that as an option, so I can program, but stays in DFU and/or fails to start the application:>"c:\Program Files (x86)\STMicroelectronics\Software\DfuSe v3.0.6\Bin\DfuSeCommand.exe" -c -d --v --o --fn test.dfu 1 Devic
