Dear Support, This is Lindy From NKG GQA team and I would like to follow up on Case No. 00206525. We would like to understand if there is any update regarding the Smelter CID002645 and CID003470 removal as requested by WD. Could you please provide the update? Below is the previous email that my colleague received for your reference. I am looking forward to hearing from you soon. Thank you!Best Regards,Lindy 

I want to send audio samples (received via SAI1 from PDM MIC) to SAI2_SD_B as SPDIF out. It does not work, because: the DMA does not seem to write the DR in SAI2: the memory is filled with audio samples the DMA seems to run (I get the HAL_SAI_TxCpltCallback and I can see via debugger that the DMA pointers are moving) but the SPDIF sends all zero: on scope, the SPDIF output is all as zero words Remark: it is on a STM32U5A5RJT6Q (LQFP64 package): the datasheet "says": not a SAI2 there (just one SAI) - but not true - it works also with SAI2, even CubeMX does not let me configure SAI2 pins (also wrong in CubeMX tool). But I can configure SAI2 and see it working (in Polling and INT mode, just the DMA fails). So, my impression: the circular buffer and DMA does not work. No idea why not: the code is generated by CubeMX. This topic is related to this thread: Solved: STM32U5xx: SPDIF out - how to configure? - STMicroelectronics Community Here is the DMA config I use: Why does it send all

Hi,I have been trying to add opus codec in my project. But I cannot able to build after adding the opus file. If anyone successfully added opus with their project help me out. I mostly get errors on 'Neon' which is used for FFT. As I searched neon is for cortex A, but the STM32WB5MMGHTR is cortex M based. I'm also adding my config file code for opus here #ifndef CONFIG_H #define CONFIG_H /* Variable leng arays */ #define VAR_ARRAYS /* Comment out the next line for floating-point code */ #define FIXED_POINT 1 #define OPUS_BUILD 1 #endif /* CONFIG_H */ Help me to add opus library with my project.

Hi All,I am using STM32G071RB-NUCLEO + X-NUCLEO-GFX01M2Questions,Do we must use external loader and which loader file name we MUST use? is the loader file - MX25L6433F_STM32G071B_NUCLEO.stdlr correct?Where can I get this loader file.Why in sample project does not include this loader?Best regards,Jiannong

Hello    My Project is based on STM32WBA55G-DK1 to develop my ble headphone.But when i called CAP_Init API, it returned BLE_STATUS_OUT_OF_MEMORY. I don't know which parameter is causing this issue. Following Parameters are my ble config. #define CFG_BLE_NUM_LINK            (1)#define CFG_BLE_NUM_GATT_SERVICES   (2)#define CFG_BLE_NUM_GATT_ATTRIBUTES (11)#define CFG_BLE_ATT_MTU_MAX         (251) Thanks

I am using the STEVAL-STWINBX1 development board and have downloaded the FP-SNS-DATALOG2 software. I am trying to get the WiFi working using the ST BLE Sensor apps, but the option 'Set Wi-Fi credentials' is greyed out.     I have even tried the classic app...   I have also tried it with the default firmware BLEDfFw, but again the 'Set Wi-Fi credentials' is greyed out. The user guide shows to click on the 3 dots in the right corner of the app....   But in my app, there are no 3 dots in the top right corner... How do I get the WiFi connection working with this board ?

To fix that i included all to a while statement but it gets stuck in else statement. I am using stm32h735. 

Hello,I am evaluating the STM32H723 with the NUCLEO-H723ZG board and I need to use the standby mode with GPIO wake-up.On the board, I have added a 10k pull-down resistor between pin PA0 (connector CN10 pin 29) and GND. I also have wire that I use to touch PA0 with 3V3.On the firmware, I use the default project for the NUCLEO-H723ZG. Then, in MCC, I activate PWR Wake-Up 1.In main.c, I add a simple function to put the MCU into standby mode that only accept the Wake-Up 1 event as the wake-up signal to reset the board. I also flash the yellow LED 10 times before calling the go to standby mode function as a visual indication.The expected behavior would be that the yellow LED blinks 10 times then it goes dark. When I touch PA0 with the 3.3 V wire, the board should go back alive and blinks the yellow LED 10 times before going dark in standby mode again.However, this is not what I am experiencing! On start up, the LED blinks 10 times then it goes into standby mode until I touch PA0. Then it re

Hello everyone,I'm working on a circuit for monitoring the bias voltage of a GM tube, which requires a high voltage of 100V. I am currently using a OA1NP22C op-amp configured as a unity-gain buffer to read the divided voltage. To minimize current consumption, I'm considering using a voltage divider with 1GΩ and 12MΩ resistors. However, this configuration still consumes approximately 9.8µA, which is higher than I would like for my low-power application.Here is a simplified version of my circuit:100V Bias Voltage (GM Tube)|R1 (1GΩ)|+----> To OA1NP22C Op-Amp (unity gain buffer) > MCU|R2 (12MΩ)|GNDMy questions are:How can I further reduce the current consumption of this voltage divider to the nanoampere range?Would switching out the voltage divider using a transistor be a viable solution? If so, what configuration and components would you recommend for achieving this?Are there alternative methods or components that could help in significantly reducing the power consumption while main

I have made multiple post at this point attempting to figure out why .invalidate is not working properly on my board. The thing is, all the examples programs work just fine. So either I am generating code in the wrong order or there is a different way to display and refresh the WIGITS on the screen without using .invalidate.QUESTION:Is there other methods or libraries I can use that the examples for my board utilize to refresh their screen that doesn't cause it to tear? There has to be a way animation play out and look smooth over time. The board I am using is the STM32H735G-DK

Hello,I followed this guide (https://touchgfx.zendesk.com/hc/en-us/articles/115002741432-Create-custom-Application-Template) to adding TouchGFX to my existing project.I'm working with IAR 8.30.1 and tgfx 4.10.0 and STM32F429ZG and FreeRTOS V9.0.0 ( with `heap_4.c` as memory manager ).Everything works well now, except texts. Every time I added components that contain text, Hard Fault occurs during redraw (*.invalidate()) it.I added virtual void handleTickEvent() { container.invalidate(); }to my ScreenView class to verifying DMA2D and LTDC configurations. All components work well. But existing just a text component causes HardFault.By tracking `LR` and `PC`, I find out that HardFault occures in `TextProvider` class.I think stack corrupted. Due to often times, `PC` is in the `DataSection`.I increased the stack size of my GUI task and `configTOTAL_HEAP_SIZE` of FreeRTOS configuration, But results not changed. Is there any other stack size ( or heap size ) limitation?Or,

Hello everyone,I am currently working on programming the display of the STM32F469I-DISCO using X-Cube-TouchGFX.What I want to achieve:I aim to create a simple application that displays a button in the center of the screen, just to test the functionality.The issue:When I run the code in CubeIDE, the display remains black, and the backlight doesn't turn on. I have made sure that "MX_TouchGFX_Process()" is called within the `while (1)` loop.Here are some additional details that might help in diagnosing the problem:- I have initialized all required peripherals and included the necessary middleware.- I have set up TouchGFX in the .part file.Despite these efforts, the display still shows no signs of life. Has anyone encountered a similar issue or can provide guidance on what I might be missing? A picture of my TouchGFX settings   Any help or suggestions would be greatly appreciated!Thank you!

I have configured a STM32 project in the ioc interface to use SPI2 - I can see it having the green check mark in the ioc interface. However when I generate code I don't see any spi driver header, and when compiling I get a:error: unknown type name 'SPI_HandleTypeDef'; did you mean 'TIM_HandleTypeDef'? I am using the STM32CubeIDE version 1.16.0 on mac.

I am attempting to get the GHS compilier to build with SPC58NG dev kit and have switched the Build settings to below  I have updated the project to include the path and commented out the error statementifeq ($(GHS_PATH),)export PATH := C:\ghs\comp_202114\$(PATH_SEPARATOR)${PATH} # $(error Please specify a valid path into GHS_PATH for ccppc (GHS) compiler)endifand it will compile but then include some strange error that doesn't really help. Is there any setting I need to fix it looks to be something in the linking process.

Hi all,I am facing issue with Open Load detection in PLAY mode and it is working fine in MUTE mode.I have flashed and tested  the example base code from STM(Autodevkit), Open Load Detection is not working in PLAY mode in this code(Placed the example code snippet below). In MUTE mode, If either or both speakers are disconnected the signal is updating with value FAULT_OPEN_LOAD_MUTE as shown below-In PLAY mode, If speakers connected or disconnected also both both conditions the value of signal is updated with "NO_FAULT_PLAY" as shown below-The structure member "OPENLOAD_PLAY" of structure "FDA_Errors_t" which is getting value from the registers is itself not updating during PLAY mode.Can anyone help me to come out of this issue. Thanks,Aishwarya UM
