I am wanting to sample the MP45DT02 microphone data. I am very much a beginner with this but I have cobbled together some code from some examples. Any input as to why I am not able to see any data through the DMA would be greatly appreciated. DMA_In...
Hi,I'm trying to use a STM32F746 to record SPDIF_Rx to SD card. I'm already got some data and save to SD card.I use HAL_SPDIFRX_ReceiveDataFlow_DMA(&hspdif, (uint32_t*)&BufferCtl.pcm_buff_32[0], AUDIO_IN_PCM_BUFFER_HALF_SIZE)and HAL_SPDIFRX_RxHalfC...
Using the STM's CubeMx HAL, I generate audio using PWM from a raw wav file at 8bit 44100hz but I am clearly using the DMA the wrong way. The resulting audio is fine but the solution has an unnecessary overhead.I am using a circular DMA with one 8bit ...
I'm working through ST Application Note AN5027 (link) to interface PDM microphones via SAI (specifically, the example given on p41 onwards). I selected a Nucleo L4A6ZG for this, due to it having SAI, but I'm having some trouble following the DMA con...
I am using the demonstration program of the STM32G0C1E-EV board. I have changed the wave_recorder.c program in order to introduce the DAC with DMA in the same parte to be able to transmit the data from the microphone to the headphones directly instea...
Hello there,I am trying to build a custom voice AI solution using STM32H747I-DISCO development kit, for which I generated the NN library code by importing a .tflite model via STM32CubeIDE and it works fine with a static Input buffer.Now, I am trying ...
Hello,I'm trying to get some audio samples with 24 bit resolution from the SAI (RX, connected to an external ADC) into SRAM via DMA.When DMA data sizes / alignments are set to WORD (32bit) for peripheral and memory everything works fine.To save some ...
I'm trying to make a guitar pedal using the ADC on my F767ZI. I want to be able to perform an FFT and other functions on a buffer of data sampled at 48kHz.I wanted to use the ADC DMAs and use the equation Tconv = 12.5cycles + SampleTime, but I have n...
Hello. I'm using an STM32G071KBU6N in a USBPD application. My application uses both internal UCPD ports.I'm working on enabling the DMA and DMAMUX for use with the UCPD peripheral, for both Rx and Tx of both ports. I'm focusing on Tx right now, and c...
Hello,I am working on application that would use microphone array. Together with STM32H735IG board I decided to use STEVAL-MIC001V1 microphone array connected via DFSDM interface. I based my project on example available in CubeMX - DFSDM_AudioRecord ...
