I enabled the SPI CRC calculation (with a length SPI_CRC_LENGTH_16BIT) in my STM32H563ZI  master application. During Tx, I want the 2 bytes of the calculated CRC to be swapped and transmitted i.e. a CRC of 0xABCD must be sent out as 0xCD 0xAB and not as 0xAB 0xCD.Can someone let me know how to do this? Thanks. 

Good morning everyone, I created a project for a client and it is now in an advanced state.All the time the project was developed with a horizontal display (we are talking about two years of work), at a certain point a larger display was used, original 800x480, new 1024x600.The use was in portrait mode.I started to have content flickering.I worked hard for days, thinking I might have a problem with buffer declarations, memory management, or other things related to hardware or settings. Today I made the macabre discovery.I positioned the landscape position of only the display on the touchgfx gui and everything magically works perfectly, naturally you can only see half of the objects as many of them are defined out of field, but no flickering of text or images.The flickering occurs between one writing and another to change the data. For a moment, new fonts appear dotted with errors or buttons or whatever redraws between one buffer and another, and all of this depends only on the orientat

Hi.Something that needs to be done FOTA while using the code, so you need to write the flash area behind it.I want to use a sash area, but it is impossible to access the document.Please tell me if you have a way to do it.   

I'm looking for the MTBT/FIT data for the STM32F103CBT6 Processor

-Hi, wanted to know, how to go about having a parallel bus shared by microcontroller and fpga. -fpga and microcontroller both r/w from external sram over the same bus.1. What should be the configs for microcontroller : fsmc in memory to memory with DMA2 burst?2. Will fpga and microcontroller both be masters in the bus. how can writing only 1 device is handled?please check 

I want do design a board with stm32h7b0zbt6, I found there is a Evaluation board with STM32H7B3LI MCU, but I couldn't find the schematic file, I just find the user manual file with RM2662, I wonder is the schematic file is opensource ?

we are observing weird error during initilization...enclosed the log dump (board2_init_fail_log.txt and ll13_01_board2_success_logs.txt)on Raspberry pi with 2 NFC03A1 boards (SPI3.0 works well, SPI0.0 fails)2 independent binaries are being used with the respective SPI and control gpios.The same board some time works(log enclosed - ll13_01_board2_success_logs.txt) but most of the time we observe Error 36 (ERR_HW_MISMATCH)Observations1. st25r95CheckChipID() fails2. ran this in a loop for 5 times and observed from 2 or 3 iteration, the chip responds with some data3. st25r95Initialize() returns ERR_NONE (st25r95CommandEcho() is ok 0x55 being received)4. st25r95SPIPollRead() returns 0 (indicating IRQ_OUT is going low.)Pls advise

I need to measure a distance within a 1 degree field of view (FOV) in front of the sensor at a distance well within the range of the sensor. I know I can't use focusing optics on the emitter side without changing the laser class - so I won't. Using a simple aperture to narrow the FOV at the detector side, I would reduce the amount of light returned by roughly a factor of 18. A lens would be more effective, but ST does not provide information about the integrated lens and the effective focal point.  Also, I cannot find the calculator AN5894 refers to "Cover glass integration guides and aperture calculator tools are also available on st.com." 

Hello,Have module bluetooths (BLE and class 1 ) please ?Thanks

Hello,I am working on a project where we have a main board and a header board connected via SPI. We have the ability to update the firmware of the main board over the air but not for the header board. We now have a need to update the firmware of the header board and we are looking at the main board downloading the header board's new firmware over the air and updating the header board's via spi and its built in boot loader. This would mean setting the Header Board's Boot0 pin to high. Unfortunately for us, this was hard wired to ground via a pull down resistor. These boards have been on the field for a few years now and recalling them for a firmware update and/or a hardware re-work would be costly. Is there a way for us to set the Boot0 pin to high via software?Thank you very much for your help.  

I think, using SAI for SPDIF Tx, can go wrong (in terms of clock config, the MCLKDIV setting):The CubeMX tool, used to configure SAI as SPDIF Tx, generates completely wrong PLL setting and codethe HAL driver, doing the config, in file "stm32xxx_hal_sai.c" can set a wrong MCLKDIV divider:resulting in half of the needed frequency for SPDIF, even you trim manually the C-code - it can go wrongDebugging SAI SPDIF Tx config on a STM32U5A5 MCU - I saw this: it seems to me, this bug (in HAL drivers) is there for years: in my old projects, years ago to get it working: I had to set SPDIF audio sampling rate to 96KHz - even it is 48KHz (but now obvious why after debugging the HAL code on this MCU).In order to get the right frequencies on SPDIF Tx, on a STM32U5A5, I have to set this PLL config:  /* 48 KHz SPDIF with scope/debug CubeMX cfg correct */ PeriphClkInit.PLL3.PLL3N = 36; //36; 36; PeriphClkInit.PLL3.PLL3P = 24; //96; 24; PeriphClkInit.PLL3.PLL3Q = 2; PeriphClkInit.P

Hi,I would like to trace the variable through SWV data trace, trace log and also I want to get the data to plot via SWV Data Trace Timeline Graph. Eventhough when I make the required setup as below, I cant get the expected trace data, could you pls help me resolve ? Enable serial wire viewer through debugger   Add the data into data trace 3. When I resume debugging I get the following values in SWV Data Trace, SWV Trace Log and SWV Data Trace Timeline Graph respectively    I would expect to see i incrementing from 1 to max value of uint16_t that is 65535. /* USER CODE BEGIN Header */ /** ****************************************************************************** * @file : main.c * @brief : Main program body ****************************************************************************** * @attention * * Copyright (c) 2024 STMicroelectronics. * All rights reserved. * * This software is licensed under terms that can be found in the

I have a STM32F7508-DK board and I'm using the last version of the STM32CubeIDE and TouchGFX.I create a project in TouchGFX (or open one of the examples that are there) -> generate code -> open project in STM32CubeIDE -> compile -> run -> works fine.Now in STM32CubeIDE I want to generate separate c and h files for each of the periphery. I open Device Configuration Tool -> Project Manager tab -> Code Generator -> and select Generate peripheral initialization as a pair of '.c /' h ' files per peripheral -> generate code again -> compile -> run -> doesn't work, black screen on the board. I don't change anything in the code, I only select the option to generate separate files.Could someone please help me where can be problem?

Hi,i saw that the VL6180X is set to NRND.I need the functions of gesture detection and ambiation light measurement.I want to use it in a new product which should be produced more than 10 years but in this case i dont think that this is the right one.Does ST recommends a replacement type? Thanks for helping.Jo

Hi Team,Currently, I have a product developed with an STM32L476RE as its main processor. This equipment is battery-powered and is used by our customers to perform measurements in remote places. After performing the measurements, this equipment is connected to a computer, and our sofware developed in LabVIEW communicates with the STM32 MCU via serial connection to download the measurement data for reporting purposes. When the MCU's firmware requires an update, our customer must send the entire equipment back to us for the update. It would be very convenient if our software could update the firmware itself. For example, if we could simply send the .hex file generated by STMCubeIDE to our customer, and they could upload the new firmware themselves. Is this possible to achieve? Just to be clear, the goal is just update the firmare, not debbug it.  

When I open the Cube Programmer (2.14) I'm greeted by a Connection error message:The server connection is not established.The network connection is required to download updates.Please check your proxy settings. I'm not behind a proxy and tried various proxy settings, reinstalled Cube Programmer and older versions, disabled my firewall and yet can't connect to the server. This seems to prevent me from flashing my STM32G431CB as the Cube programmer needs to download something for that. When I try to program a STM32F446ZE everything is fine. The error message while flashing is:stm32 Error: failed to download Segment[0]Error: failed to download the File Thank you!

Hello,I was wondering how to edit the analogConfigTbl_NFC08A1.c file in order to change the chip's operation from differential to single ended. I have looked at datasheets and it is very confusing what register-mask-value should be used to enable single ended operation for the antenna.Also, how would I go about removing AAT from the chip's operation. Do I just delete the AAT entries in the analog configuration file? Regards,William

I have a Nucleo STM32F767ZI with SPI2 and SPI3 configured for 8 bit mode.  When I send data to SPI2, I see the correct data on SPI2 MOSI, but just a static high level on the SPI2 SCK using a scope.  Using SPI3 I see both the SCK and MOSI working with no issues. It seems to me that some other configuration might be necessary to get SPI2 to work properly.   SPI2 pins:PB10: SCKPC2 MISOPC3 MOSI. I tried remapping SCK to another pin, but that didn't resolve the issue. The MX configuration both SPI2 and SPI3 is: Parameter Settings Mode:Full Duplex MasterHardware NSS Signal DisableParameter Settings:Frame format MotorolaData Size 8 bitsFirst Bit MSBPrescaler baud Rate Divisor 16 (3.375 Mb/sec)CPOL LowClock phase 1 EdgeCRC Calsulation disabledNSSP Mode disabledNSS Signal type SoftwareHere is my test code snippet: ```uint8_t rx_buffer[2];uint8_t tx_buffer[] = {0x55,0xAA}; while(1) {volatile int res = HAL_SPI_TransmitReceive(&hspi3, tx_b

I debug up to hear and the flow of the code is blocked in this function,(after adding freeRTOS) in  the project. i don't know what is the error. i had used the low level API which is avaliable in the document. the flow is like this in the main function. at AEK_903D_Init(). it is blocked. and not coming out of that API. please help me out.

The STM32U0 Series is very interesting, and I would like to use the small WLCSP package in a design for a new product, but the  STM32U031G8Y6 is still in evaluation. Does anyone know when the STM32U031G8Y6TR will be available for purchasing?Thank you!Vlad
