Unable to communicate with SPI bootloader

Hi,​I am trying to use the ROM bootloader on the STM32G071 to change the contents of specific flash sections. I was able to enter the bootloader just fine, at least I think so because I can see in the debugger how different points in the address spac...

any sample code available for low pass filter using CMSIS library function.

Hi , I am using STM32H745XI microcontroller . I want to implement low pass filter for integrating Rogowski coil current signal on CM7 core. For reference ,Any sample code available for low pass filter implementation using CMSIS library?Thanks and Re...

Hi , We are working on stm32's nucleo-G0B1RE.we are facing error while we upgrade firmware in runtime using I2C port.we are getting flash erash error .Active peripheral during Flash write operation is watch dog , SPI for accelerometer data read.

How can I improve audio quality on BSP example (audio loopback program) for STM32F769I-DISCO? I've enabled all 4 microphones by modifying the example but the quality of audio is very low. What else do I need to modify in the program?

I changed the slot number in Audio Codec audio interface (SAI) - stm32f769i_disco_audio.c

How to enter UART bootloader on STM32G030K6T6?

I'm trying to activate the UART bootloader after receiving input (from either a button press or from parsing a command from UART interrupt). I see from the G030x programming manual that to do so, I must set bits of the FLASH_OPTR register as nBOOT1 =...

Hello, Can anyone please help me in Low level(LL) SPI driver for STM32F7 microcontroller?

I have been trying to establish an SPI communication using STM32F7 microcontroller using Low level drivers in STM32CubeMX. I am facing issue Reading from the DR register. I need to read 8-bits but the values are getting stored as 16-bits. Also the DR...

FreeRTOS implementation with X-Cube-BLE2

I'm trying to implement a BLE task in my FreeRTOS application with the X-Nucleo-BNRG2A1 shield. I completed the BLE application (X-Cube-BLE2 package) without FreeRTOS and it has been working fine. For implementing the FreeRTOS, I have been looking in...

I try to implement UART DMA reception in circular buffer with reception with idle in STM32F429 Discovery with MCU Package for STM32F4 in Rev 1.27.0 . IDLE event is not called when number of recived char rise DMA_TC.

What i expect is that my interrupt callback (HAL_UARTEx_RxEventCallback) will be called with those event :DMA_Half_Transfert Complete -> OKDMA_Transfert_Complete -> OKIDLE_Event -> OKAll interrupt work individually but...1) Receive buffer is emptyI s...
