Hi, I'm trying to check I3C protocol with NUCLEO-H503RB and IKS01A1.I just followed below link for I3C. https://wiki.st.com/stm32mcu/wiki/Getting_started_with_I3CAnd I can see that the master transmit the data but there is no ACK from the slave.(I've attached the scope shot).I was trying to buy IKS01A3, but it was out of stock, so I just bought IKS01A1. Because it seems same IC. Is it okay?I've also tried below example from the github, but result is same. https://github.com/STMicroelectronics/STM32CubeH5/tree/main/Projects/NUCLEO-H503RB/Examples/I3CPlease help me to find a way to check I3C.     

Hi  I am trying to RTOS on my device STM32-H563ZI I get a hard fault when I hit the function osKernelStart(); in the main loop When I started debugging ,my code seems to get  hardfault after vStartFirstTask in function xPortStartScheduler() I am trying to toggle LED in the task  from this example https://www.youtube.com/watch?v=OPrcpbKNSjU Thank You.

Ref: https://www.st.com/en/embedded-software/stsw-stm8006.html#overviewI have downloaded the software above which is a companion to AN2659 but there are directories not mentioned in the application note.  Can anyone tell me what the RIDE and EWSTM8 directories are please?Thanks.

@Guillaume K, @Jocelyn RICARD Since my previous question on the same topic (see here) I have reviewed probably all the MCUboot/TF-M-based solutions available for ST MCUs. There are currently four options that I am aware of:TrustedFirmware-M (TF-M) using the latest MCUboot, implements well-documented PSA-API, actively developed and maintained by community.Regretfully, this solution appears to be no longer actively supported by ST, STM32U5xx HAL version is 1.0, so no support for new ST MCUs.ST's TFM, described in AN5447 and UM2851, still available as a part of the STM32Cube_FW_U5_V1.4.0 package under /Projects/B-U585I-IOT02A/Applications/TFM folder, probably abandoned, removed from GitHub for this reason.Secure Boot and Secure Firmware Update (SBSFU), described in UM2262 and partially in AN5447, STM32U5G9 supported, based on relatively old TF-M 1.3 (current version is 2.0, version 2.1 to b

RTC3 of some newer STM32s introduce a RTC mixed mode, where both binary part (32-bit down-counting sub-seconds register SSR) and classic BCD calender (TR/DT) mode are operational.In my case I am using this for classic style BCD alarms together with binary mode timers used by the CubeMX generated LoRaWAN stack.This works perfectly fine until I try to set the BCD calender time part with HAL_RTC_SetTime.It turned out, that as soon as RTC->TR is written, RTC->SSR is reset to 0xFFFFFFFF. As all timers backed by the binary mode rely on some SSR timestamp, they fail.I tried backing up SSR and writing back after RTC->TR write, but it seems to be read-only.Am I missing something? If a mixed mode has been introduced, I doubt normal behaviour is that the BCD part cannot be set anymore without affecting the binary mode part.

Hi, I am trying to understand the difference between blocking/non-blocking rfal apis.  ReturnCode rfalNfcvPollerReadMultipleBlocks( uint8_t flags, const uint8_t* uid, uint8_t firstBlockNum, uint8_t numOfBlocks, uint8_t* rxBuf, uint16_t rxBufLen, uint16_t *rcvLen );  It seems to me that the above api is a blocking one. How can I achieve the same functionality in a non-blocking way ? The reason I am asking this is because it seems that this api is taking too much time to execute (Without the time required to perform I2C read). Is my understanding correct on the RFAL library sequence for the above api ?RFAL library request ST25R3916 for the requested amount of data.RFAL waits in a busy wait loop until interrupt pin changesOnce the interrupt pin changes, RFAL library performs read from ST25R3916.I am concerned about step 2 as it is a busy wait loop and other threads seem to be starving. 

I did not find any solution of Bootloader for CAN2.0A or CAN2.0B with SMT32. Currently i am using below part no. MCU-'STM32G0B1CCT6' CAN IC-'ISO1044BD'

Hello community! I'm trying to start a project to test a new board Nucleo-H755ZI-Q, but i don't now how dual nucleo works and if is a board problem, code problem or a debug config problem.Follow some ST docs tutorial or Youtube tutorial give the same error: The CM7 and CM4 debug open, but if i click on run debug, the project debug close and cube IDE back to the code editor.Here is the clock config print:Clock config page 1 Clock config page 2Here is the pinout config:pinout config The code CM7 and CM4 is just LED blink on infinite loop:/* CM7 code */ while (1) { HAL_GPIO_TogglePin(LD1_GPIO_Port, LD1_Pin); HAL_Delay(250); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ /* CM4 code */ while (1) { HAL_GPIO_TogglePin(LD2_GPIO_Port, LD2_Pin); HAL_Delay(500); /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */ The Debugger CM7 config:CM7 Debug page1 CM7 Debug page2 The Debugger CM4 config:&

Hi Team, We have our customized projector majorly focused on educational field purpose. Its a short through projector with 16:9 aspect ratio. We are planning to implement Auto keystone and Auto Focus using VL53L5CX TOF sensor. Do you have any driver support for this particular implementation.?? Any Knowledge article related to this implementation??     Thanks & Regards Deep_Bang   

Hi,I have a question regarding the possibilities and best practises of the early wake interrupt generated by the window watchdog.Is it possible to use the EWI to refresh the watchdog? And if so, is it actually a good idea and reliable?To describe the reason why I am asking briefly:I receive data over UART in fixed intervals, which refreshes the watchdog under normal conditions. If no data is received after a certain time I assume the connection is faulty, set a failsafe/timeout flag and refresh the watchdog. This would be triggered by the EWI and should not happen under normal operating conditions, it is purely a failsafe measure.Technically no reset is necessary or even wanted in this case. I know that this should be realised with a normal timer interrupt, but I am using all of the timers for something else. I could probably make this work with the RTC or a capture compare interrupt from timer 1, but ideally I do not want to use the same timer for two different functionalities as the

Hi there, I am working on a project using the STM32H755 zi that has 1 USBC port, can we use the same port for uploading the code, UART Communication and powering the device instead of using ST-LINK? Or is there any way to use ST-LINK for communication? Thanks for any help.

Hello, I'm using the STM32F469NiH6 to try and do a certain number of SPI transactions (let's say 12 bytes) at regular intervals without core intervention, using Timers and DMA. And I have a couple of questions concerning this (I have had a look into the RM, in particular the peripheral registers, but a second opinion would be useful in case I missed/misunderstood anything) Is there a way for any of the timers to enable/disable the SPI directly?Is it possible to use DMA (triggered by a PWM edge, for instance) to enable/disable a different peripheral (like SPI) by writing to its configuration register (setting the Enable bit) ? If there's any help, official examples, community forum threads, or pointers to the Reference Manual, that definitively answer my questions above, that would be greatly helpful! Thanks!

Hi team.I want to drive BLDC motor in 6-step method like below figure.Is there any sample code for this method? Slide Link 

Hi all,I am trying to config the LTDC, after config and generating the code by cubeMx, I see some config like the below:   pLayerCfg.Alpha = 0; pLayerCfg.Alpha0 = 0; pLayerCfg.BlendingFactor1 = LTDC_BLENDING_FACTOR1_CA; pLayerCfg.BlendingFactor2 = LTDC_BLENDING_FACTOR2_CA;  My config is the same as below:And I have tried to change some items for exploring as below:I can easily understand that L1_Alpha controls the transparency of Layer1, but others seems not clear.I am confused about what these items mean. Can some document introduce me to how to calculate the RGB result?Thanks a lot.

I could cry... ("rrrr", the more I dive into latest STM MCUs - the more I get frustrated - LOL)The datasheet for STM32U5A5, LQFP64 package, tells me: there are PB15 as SAI2_SD_A and also PC12 as SAI2_SD_B.But the CubeMX does not let me configure these signals as SAI2: I need just one pin (one of them, preferred as PB15 = SAI2_SD_A, for a S/PDIF output).But:if I load and see the features of this STM32U5A5, LQFP64 package in CubeMX:it tells me just SAI = 1- it is actually not true: the datasheet shows me a complete signal set "possibility" for SAI2 as I2S!- SAI2_A and SAI2_B are complete on the STM32U5A, even for this package!if I try to configure pins, e.g. PB15 as SAI2_SD_A, or PC12 = SAI2_SD_B:the SAI2 features for these pins are not there (not in list) - using CubeMXIs this a "bug" in the CubeMX tool? (I hope so!)Or:based on datasheet - still possible to use SAI2 and one pin as SAI2_SD_A or SAI2_SD_B as a S/PDIF output?How to generate code for SAI2_SD_x as S/PDIF output? (assuming, c

I have a board using STM32F103CBT6 chip.  After flashing the board once (through CubeIDE v1.14.0 with ST-Link v2) I cannot flash it again and keep getting the message "No target found".  Here's a snapshot of the chip circuit:  When I power up the board it flashes an LED that I programmed so I know the initial programming worked.  But I can't connect again. Any ideas would be appreciated. 

I am using STM32F407G.I am attaching a main.c (that use DMA) that reads simultaneously the voltage coming from 3 potentiometers connected to 3 channels of ADC.In the code, if you try to change "volatile uint16_t adc_value[3]" to "volatile uint32_t adc_value[3]" this is what happens:Huge values (above the upper limit 2^n with n = num bits) are displayed.I don't understand why this happens."adc_value" is the number read by the ADC while "adc_CH1_value_volt" is converted to volt (of the 1° channel)
