hello,  I'm working on ST25DV64KC, especially on FTM mailbox function and EH power supply. Current situation is I need to test maxium frequency avaliable for supplied by EH(STM32L476VGT6 with ST25DV64KC) while communicating through mailbox(FTM). The plan is to modificate FTM part(of DISCOVERY firmware), and remove all related part of LCD/Touch screen source code, let a data transfer triggered by SW1 button and also compatibility the protocal  used on Andriod app.  However, I found it difficult to use the firmware on FTM because of lack of documentation of the part of source code, as it highly abstracted. So i wonder if there is other way（like some other example project/code provided) or a detailed docmutation i can refer to? thx  analysis only on code is suffering :(  

Hi,Got a new MCU with LSI2 from the distributor. I want to use it for the 2.4 GHz RADIO sleep timer, but can't find LSI2 register settings in STM32CubeMX.Additionally, I'm curious why the STM32CubeWBA version V1.3 doesn't support the STM32WBA52 series product. Sincerely. Eric

Hello everyone. I want to understand the CORDIC engine, using the nucleo-u575zi board. The guide says that the cordic uses data in q1.31 format. Could please someone explain how to convert results into an ordinary int value? And how to convert an int value into a q1.31 value for loading into the cordic?

Hi,I need to add OTA functionality to a CubeMX generated project. The readme.txt file from the BLE_HeartRate_ota project has a note saying "Remove the update of SCB->VTOR in the file system_stm32wbxx.c". On my current CubeMX generated project the SCB->VTOR line is protected with a macro as follows: #if defined(USER_VECT_TAB_ADDRESS) /* Configure the Vector Table location add offset address ------------------*/ SCB->VTOR = VECT_TAB_BASE_ADDRESS | VECT_TAB_OFFSET; #endif /* USER_VECT_TAB_ADDRESS */ I am using CubeIDE and noticed that this macro is not defined by default, which doesn't make sense.Where is the VECT_TAB_BASE_ADDRESS defined?Is it OK to use another define macro to disable the line instead of deleting it? Asking this because comparing the BLE_HeartRate vs BLE_HeartRate_ota the lines were completely removed.

Hi,I have been struggling to get my head around the way custom container call backs work.I have a custom container that has three flex buttons, this container is then used on a single screenview multiple times.I'd like to be able to identify the flex button pushed along with knowing what custom container this came from. Sounded simple and i am sure it is, my head is just failing to get around the multiple files that this process spreads across.

Dear all,Apologies if this is a naïve post.I am trying to find a processor for the product that I am working on with larger RAM and FLASH but it must remain pin compatible to minimise code changes. The current processor is this "STM32F756ZGT6". With the current application its RAM is throttling at 100% and more features are still pending to be added. Therefore, if I can find another processor with the same pinout then the problem will be resolved.Any help would be appreciated please? Many thanks

in https://www.st.com/content/st_com/en/products/embedded-software/mcu-mpu-embedded-software/stm32-embedded-software/stm32cube-mcu-mpu-packages/stm32cubef4.html there are the MCU package and the patch, the first can be installed from CUBE IDE with "manage embedded software packages" but when I select the second the tool says that is not a compatible file

We are using STM32H743IIK6 microcontroller. There are analog only pins, designated as ANA. What is the use of these pins? Also, what will be the difference when GPIO is used for analog functionality and ANA pins are used for the same purpose? 

Hi.I want to acquire data from a 5M pixel image sensor (for example OV5640) with YCbCr4:2:2, 8bit using DCMI.(I want to process the image data, so I need to transfer it to memory using DMA)However, AN5020 and RM0481 (Rev1) mention a maximum of 2048*2048, so I'm about to give up.This description seems to have disappeared in the latest RM0481(Rev2),, but I would like to know if the above description is accurate and if there is a limit on the input size.If you have any experience using it without any problems, I would appreciate any information. 

Hi Team,I am working on a project involving the STM32H5 microcontroller and I am in need of information on how to manage the keys securely for encryption and decryption. I have been unable to find a document that covers this topic specifically for the STM32H5.Could you please provide me with information on how to manage the keys securely using STMCube Programmer, Trusted Package Creator (TPC), or any other methods available for the STM32H5?Thank you for your assistance.P.Hitesh

Dear Members,How can the speed of displaying the value of HAL_GPIO_ReadPin when reading a pwm signal be equivalent to the speed of displaying the value in another variable located outside WHILE ?I made a code to read the pwm signal to find out whether the pwm signal is in high mode or low mode using HAL_GPIO_ReadPin. When mode is high it will send a value of 1 and when mode is low it will send a value of 0. I tested it by reading a 1Hz frequency which has a duty cycle that changes every second starting from 10%, 30%, 50% and I set a delay of 100ms on WHILE.When I looked at the code output with UART, I saw that the time value in high mode for each duty cycle that the program read was correct. However, the number of values 1 appearing when reading one duty cycle does not correspond to the size of the duty cycle being read. Here are the results of the code output: DUTY CYCLE 10%[10:01:46:124] 1C | Ton_ms: 00099.90 | Ton_us: 99899.98 ␍␊[10:01:46:225] 1C | Ton_ms: 00099.90 |

Hi,When creating a custom template BLE app in CubeMX everything works fine while not changing the UUID of service1, it builds and compiles well. But if I change the UUID to my own UUID (with UUID 128 input type to full), after generating the new code an error pops up: undefined reference to `COPY_UUID_128'It appears the macro COPY_UUID_128 is missing now, after I add it myself in the USER CODE area, it compiles again (custom_stm.c):   #define COPY_UUID_128(uuid_struct, uuid_15, uuid_14, uuid_13, uuid_12, uuid_11, uuid_10, uuid_9, uuid_8, uuid_7, uuid_6, uuid_5, uuid_4, uuid_3, uuid_2, uuid_1, uuid_0) \ do {\ uuid_struct[0] = uuid_0; uuid_struct[1] = uuid_1; uuid_struct[2] = uuid_2; uuid_struct[3] = uuid_3; \ uuid_struct[4] = uuid_4; uuid_struct[5] = uuid_5; uuid_struct[6] = uuid_6; uuid_struct[7] = uuid_7; \ uuid_struct[8] = uuid_8; uuid_struct[9] = uuid_9; uuid_struct[10] = uuid_10; uuid_struct[11] = uuid_11; \ uuid_struct[12] = uuid_12; uuid_struct[13] = uuid_13;

I want to use STM32U5A5 SAI1 to generate via SAI1 a master I2S, with 24bit sample words.I need 24bit because sending out afterwards as S/PDIF (via SAI2) needs 24bit sample words (as I understand: SAI2 as S/PDIF Tx is "forced" to send as 24bit samples - only).I get just 16bit PCM or 32bit PCM, but not 24bit! WHY?My config: hsai_BlockA1.Instance = SAI1_Block_A; hsai_BlockA1.Init.AudioMode = SAI_MODEMASTER_RX; hsai_BlockA1.Init.Synchro = SAI_ASYNCHRONOUS; hsai_BlockA1.Init.OutputDrive = SAI_OUTPUTDRIVE_ENABLE; hsai_BlockA1.Init.NoDivider = SAI_MASTERDIVIDER_ENABLE; hsai_BlockA1.Init.FIFOThreshold = SAI_FIFOTHRESHOLD_EMPTY; hsai_BlockA1.Init.AudioFrequency = SAI_AUDIO_FREQUENCY_48K; hsai_BlockA1.Init.SynchroExt = SAI_SYNCEXT_DISABLE; //SAI_SYNCEXT_OUTBLOCKA_ENABLE; //SAI_SYNCEXT_DISABLE; hsai_BlockA1.Init.MckOutput = SAI_MCK_OUTPUT_DISABLE; hsai_BlockA1.Init.MonoStereoMode = SAI_STEREOMODE; hsai_BlockA1.Init.CompandingMode = SAI_NOCOMPANDING; hsai_BlockA1.Init.TriState = SAI_OUT

Hello,I am trying to do some ray tracing simulation for your VL53L8CH in a specific environment. I was wondering if you have any data beyond the "Field of Illumination" diagram for your VCSEL emitter (I assume you make your own emitters in-house). An "IESNA TM25" or "SPEOS" ray file would be amazing, but even just a maximum output power in lumens, watts, candelas, etc. would be helpful. That way I can at least know what the percentages in the "Field of Illumination" diagram mean. Also, if you have any detailed CAD on your chip that would allow me to place the emitter in the correct location on the sensor, that would be helpful as well. I have recreated it from your datasheet, but that doesn't have details on how deep the VCSEL is or what shape it is.Thanks,Garrett

Hello everybody!I am using STM32F429 as my central controller for a project. I need to read 20 ADCs and process the signals by the 10 kHz sampling-time. I am using 14 channels of ADC1 and 6 channel of ADC3. Before, I have done it for one ADC when I used a timer as trigger and DMA for transferring data. The timer triggered the ADC conversion and DMA transferred the data to a buffer. When the conversion was finished, by using "HAL_ADC_ConvCpltCallback(ADC_HandleTypeDef *hadc)" function I could get the ADC values and run the control loop.Now I have two different ADCs and it seems it is complicated to use two DMAs and one timer as trigger. I would be so grateful if you could suggest a solution!

Hi, I'm trying to fix an old device (late '80s/early '90) which uses, on its digital logic board, an IC in a PLCC44 package which is marked with the ST logo and "ICWA B22WE9335". I can't find any datasheets nor even any mention of its existence anywhere on the internet. Does anyone know where I might find some info on it? Also, I think it might possibly be some kind of programmable logic device (it's hooked to a 6805 MCU's data/address busses and to some external latches) with a custom part number, if so, any idea which device it might actually be? None of the PAL/GALs I can find in the databooks uses a package with that many pins.Thanks in advance

Hello everyone, im trying to understand how the configuration and the use of the ADC is usued on a NUCLEO401RE. I've read the datasheet and reference Manuel but still its not clear.I have configure the pin A0 on CubeIDE to be an ADC input. But now i don't now how to handle the software part and which functions (HAL or not) to use to read this entry and get their value. Could someone help me code this ? or give me some indications maybe ? Im thanking you in advance for your kind help.

For our motor control project we're using a driver IC with integrated opamp stage intended for current measurement.This opamp stage inverts the current reading compared to the Current sensing signals conditioning model, see here:To correct the current reading, could I simply put a negative gain value?According to an article about an older version of the MCSDK, that didn't work. Would that be possible with the MCSDK Version 6.2.1?

Hello, I am new at the STM32 World.  I started to buy a nucleo-f767zi and it worked fine.  I was not able to get the debug Console running. Like other too.  Because of that I bought the extension Board  x-nucleo-GFX02zi which should be working fine with the F767ZI.  Now I tried with CubeMX to installed the Hello World Example provided.But now I get the Message that these Packets is not Support with CubeMX 6.11. It should be support by Version 6.7 until 6.8.2. I tested 6.8.2 and 6.8 but without any changes. It seams like the SPI does not fit together. Always I got no solution found.  Does the GFX02zi can be used with the F767ZI? Or do I have to everything new.  I am going a bit crazy.  Is there anyway a working step by Step intruduction for Add a Display to a STM32.  Thanks for any help best regardsCarsten 

Hello,I'm trying to use the ST25 java SDK. The software_guide pdf document says I need to load in my IDE the natives libraries the SDK will need. It says I will find them in t \readers\st\resources, but in this folders there is only windows/x86 for the DLLs, and no windows/x64 as is mentionned in the document. And I can't use the 32bits version in my 64bits JVM. Am I missing something, or did the x64 folder was forgotten in the release ?Extract from the pdf guide :the readers/st/resources/windows folder from the sdk :
