Good Morning Ladies and Gentlemen, Could you communicate in a short way the size of the contact drill-holes (stm32f411 - CEU) ?The diameter in AWG size would be enough.We also are interested in further documentation-links regarding it. In student words"Have a nice day"

How is this possible with the #ifndef catch?

Hi there,after installing SPC5Studio v6.0 and opening some sample projects (even an empty one) for SPC582Bx mcu, I found no way to alter compiler and linker options.In eclipse-based IDE (like SPC5Studio) this is normally accomplished opening the project Properties, under C/C++ Build/Settings. Please note that sample projects generate and build fine; I have no board to try UDE debugging but this is outside the scope of the current question. Is there some other way to change compiler and linker flags? Thanks for the support,FP

Which one is the best spc5 board to get for engine and dashboard data collection,usage and sensors integration and communication and also compatible with autosar framework 

I have 2 STM32F411RE-EVA Boards. I want to use one of them as SPI Master and the other one as slave and i want to receive data when a certain boolean goes high and triggers the slave. I want the slave one to send me 8 bits of data but i want to receive it in the DMA on master so my Master Module can continue to work on other functions when the transfer is happening. When the whole data transfer is complete i want to blink a led. I tried to work with DMA interrupts but i was not able to do what i wanted because im a beginner on STM. A help would be very useful since i cant find any sources on internet to achieve this using STMCubeIDE

any tips on how to enable and debug pll4_r and fdcan_k clock?

Hi, I am currently using an ASM330LHH MEMS, and seem to be getting erroneous spikes in data from the temperature sensor (see attached image). Please can someone advise on what this may be, or if you have experienced the same issue? I have been working through the temperature decode in my data acquisition (which seems to be okay), but I could be wrong. Many thanks. 

I'm using XCube for develope. Can I use NFC6 for this board?

I'm using STM32H573IIK6TR and I download its IBIS simulation model from st.com [stm32h562_563_573_ufbga201.ibs]There are a lot of pin model, but i cannot understand what is the correlaction between the datasheet and ibis model. For example: I'm using pin H14 as SDCLK in high speed mode. In IBIS model pins have the following models: low speed (io8_ft_spi_ls_3v3), medium speed (io8_ft_spi_ms_3v3), fast speed (io8_ft_spi_fs_3v3) and high speed (io8_ft_spi_hs_3v3). In datasheet there are 4 mode: low, medium, high and very high. So, I think that "high mode" in datasheet correspond to "fast speed" in IBIS model, but results don't correspond at all. 

Hello,I'm trying to set up a micro sd on a nucleo-u575ZI through the sddmc1 with a port of FatFs.I am using a PmodMicroSD all wired up for 4 bits and the card detect on a GPIO.I am testing 3 sd card 16GB, 32GB and 64GB.I have confirmed that all 3 are working in 4 bits mode though SDMMC on a STM32L4R9I Discovery with FatFs. My current implementation on the U575 works only in 1 bit mode. All 3 cards are working and ExFat is enabled on FatFs and I can read and write files no problems.When I change the SDMMC to 4 bits configuration on the U575 only the 16GB sd card works. The other cards gives me a FR_NO_FILESYSTEM when trying to mount.I believe it comes from this line in ff.cif (fmt >= 2) return FR_NO_FILESYSTEM; /* No FAT volume is found */I'm a bit loss and I was wondering if anyone had any ideas what might go wrong. I ported FatFs from the STM32L4 CubeMX generation. (FatFs version 0.12c) I believe FatFs has exFat bugs in 0.12C as state in the change logs of 0.13 but I am unsure

Hello, I am working with a STM32H743 with RTOS and LWIP, using LAN8742 as PHY. I have developed a custom board with this setup and it has been working very well.Now, after almost an year, the new production lot does not work anymore: when the firmware starts, the 2 leds connected to the RJ45 plug blink simultaneously. The producer assured me that he used the same components, only the PCB has been produced in a different lot, same master.I tried to handle the nRST pin by software, delaying its assertion as descripted in the LAN8742 datasheet but it's no use. With the "old" boards that pin was left high for the whole time, no need of hardware reset via that pin. Is there a logic table that describes what the actual LED meaning is? I think they are showing some kind of error state but can't figure out which.Big thanks in advance!   

I want to play audio on STM32F4 Discovery board. Audio is stored in SD card which connected by SDIO. On discovery board, I see below connections.I2S3_SCK -- PC10 -- (SCLK) CS43L22I2S3_SD -- PC12  -- (SDIN) CS43L22but PC10 & PC12 are also connected to SDIO_D2 and SDIO_CK.  SDIO has no alternate pins. Any suggestion on how to move I2S3_SCK and I2S3_SD to PB3 & PB5 alternate pins on discovery board.

Hello all,I am developing a touchGFX application on STM32F7 with the frame buffer stored on an external QSPI flash. While app is running, I need to write data to this external memory but, to allow the flash write, I have to exit the memory-mapped mode. On this configuration the GUI task can not access the frame buffer so I have tried to block its execution. I have implemented it this way:1- System starts: QSPI flash configured in memory-mapped mode (GUI task working fine)2- Disable LCD and DMA interrupts and exit memory-mapped mode3- Write flash4- Enter memory-mapped mode and enable LCD and DMA interruptsSince the data is received from modbus communications, I repeat steps 2-4 on each message reception until I have written all data on external flash. This solution works sometimes but others the GUI task seems to crash and the screen is not refreshed anymore.My question is: what is the correct way to block GUI task (or frame buffer access) so that it could continue its normal function o

hello  I'm using a STM32H573-DK board for engineering samples. so. I'm run a example this link but provisioning.bat files does not run at 'Step 3 : Provisioning'How to fix this problem?   

Hi, I'm doing a low-power project using the STMF401CCUx MCU.  I require only 1 I2C, 1 SPI, 1 GPIO Interrupt, and 2 GPIO input pins.    I won't be using any ADC or DAC parts, so is it fine to leave the VREF+ pin unconnected?  Does it source any current?    Any other recommendations on the PCB design is also appreciated. Thanks!

Hello, It is not clear to me if I can set stm32wb55 to advertise for connection (e.g., fast, slow)  during sleep mode.In case a client connects to me, will I get a connection event that will wake CPU1?What are the sleep modes( power consumptions) of each CPU in the best case? 

Is it possible to control the VL53L1X ToF sensor using the stm32f407? because I am looking for the average website using the nucleo board.

Hi! I am using the SensorTile.box PRO in Expert Mode and try to log both Gyroscope and Microphone on the SD Card. When I try to upload the App I receive this error message: "There was a timeout error loading the App on the board". If I make an App to log only Gyro or only Microphone the App is uploaded and everything runs ok (in the first case a .csv is generated while in the second a .wav is generated). Thank you!

Hello all,Kindly guide us how to resolve the following issue or share the sample code,We are using MCU STM32U585QII6QTR. In this TrustZone is not enabled.We are trying to change the RDP level from 0 to level 1 and from level 1 to level 0 from software.We are successfully able to change from RDP level 0 to RDP level 1 in software. But when we try to change the RDP level from level 1 to level 0 the regression is not happening.The regression is not working with and without RDP regression password(OEM1KEY). RDP level 0 to level 1 change code:void ChangeRDPLevel(FLASH_OBProgramInitTypeDef *pOptionsBytesStruct){HAL_FLASH_Unlock();HAL_FLASH_OB_Unlock(); pOptionsBytesStruct->OptionType = OPTIONBYTE_USER | OPTIONBYTE_RDP ; //Configure USER and RDP// pOptionsBytesStruct->USERType = OB_USER_nBOOT0;// pOptionsBytesStruct->USERConfig = OB_BOOT0_FROM_PIN;//Set to boot from pin (UART)pOptionsBytesStruct->RDPLevel = 0xDC; while(HAL_FLASHEx_OBProgram(pOptionsBytesStruct) != H

Dear ST,I try to use SPI1 in full-duplex slave mode with hardware NSS and interrupts.Interrupts work fine, the only problem is that data is all 0After connecting the logic analyzer I noticed that the CS and SCK signals are ok but the MOSI and MISO are low. I generate the SPI data using MCP2210 breakout board, it works fine if I connect only the logic analyzer to the MCP2210 all signals are fine. when adding the nucleo in the circuit MISO and MOSI are pulled low!!! I use CubeMX for configurationpins are:PA5 - SPI1_SCKPA6 - SPI1_MISOPA7 - SPI1_MOSIPA4 - SPI1_NSSHas anyone ever seen anything similar.. where to look for the issue ?Thank you

Hi, I am completely new into microcontrollers. And while working with keil as well as smt32cube ide i found options such as debug and release. Can someone please tell me whats the difference between both, what benefit one has on other and when to use when. Thanks and regards

Hello,I'm trying to use the I2S transceiver on a STM32H7.I did a first simple experiment using the HAL function: HAL_I2S_Receive_DMAI use a basic loop in the main:while (1){  if (i2s_bsy == 0) {    i2s_bsy = 1;    i2s_status = HAL_I2S_Receive_DMA(&hi2s1, samples, 512);  }}i2s_bsy is cleared in: HAL_I2S_RxCpltCallbackvoid HAL_I2S_RxCpltCallback(I2S_HandleTypeDef *hi2s) {  i2s_bsy = 0;}Doing that the call back is called only once, I found why, in HAL_I2S_Receive_DMA it is mentionned that the I2S core is kept enable to avoid losing sync but it seems that configuring the DMA while the I2S is enabled doesn't work.If I test disabling i2s in the callback to be sure to reconfigure DMA each time with i2s disabled then it "works".void HAL_I2S_RxCpltCallback(I2S_HandleTypeDef *hi2s) {  i2s_bsy = 0;  __HAL_I2S_DISABLE(hi2s);}I think either something is wrong in the HAL blocking the DMA from retriggering or it's not possible to retrigger DM

Hello, I am not experience enough in electronics to know if this is a dumb question but I'd like to know what the max current of the NUCLEO boards means. Is it the maximum current draw or the limit that is input from the output source? I'm wanting to power my board from a car charge port but most of the ports I find are 5V 2.4 amp and the board says the max current is 500mA. In the future if I decide to not power from USB and want to from the 3V3, that connection is attached to a current regulator that has a max current of 1.2A but on the max power setting the max current for the 3V3 is just '-'. Could I get some further explanation to how these things work? Thanks!
