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...
