CMSIS DSP FIR and IIR filters not working correctly

Hi all,I am working with CMSIS DSP alghoritms and currently I get stuck with FIR and iir filtersWhen data are predefined in float32_t arrays everything works fine like bellow for FIR lpfBut when i am trying to use the same filter for array from ADC i...

Is it possible to send other data over uart after setting up uart_tx circular dma. I am using STM32L4 series. I want to send some data on pin change interrupt while dma is still working

ADC w/ Binary Semaphore: ADC Callback Function Never Called

Hello,I am attempting to setup a project that displays the potentiometer voltage from the ADC on PA0_C on the STM32H7B3I-EVAL evaluation board onto the provided display. To do this, I am using a Binary Semaphore to handle the task of notifying the LC...

CAN Transmit questions

I'm trying to just get a CAN message sent out to prove the hardware on a board. At the moment, the Tx pin is high and even when I attempt to send a message out I get nothing. My first question is:If there is nothing else attached to the CAN bus (post...

STM32 has internal watchdog allocated each core independently?

How did I miss this? 32KHz/64KHz DMA using LSE

Just in case others have missed this feature (like I did). You can generate DMA at 32768Hz and even 65536Hz rates with the LSE if you use the "TIM15 input capture 1 is connected to LSE" option and set the timer to "input capture" mode and capture one...

Multiple bus master access to OSPI PSRAM on STM32L4P5G-DK

I'm using a STM32L4P5G Discovery Kit board with the external OctoSPI PSRAM in memory mapped mode to store a framebuffer for a SPI display. The board runs at 120MHz and uses the board support file by ST for initialization. The SPI transfer to the disp...

Why there are big execution times (peaks) when doing PIL tests on both QEMU emulator and STM32F769NI board ? (issue not present when doing SIL tests)

Hello, I'm wondering why there are big execution times (peaks) when doing PIL tests because the execution times are smaller when doing SIL tests (no peaks). Please find attached the comparison between SIL and PIL. Do you have some explanation and som...
