PDM mic will be set up as 8 or 16 kHz sps. icm will be set up as 4kHz sps.data is received in sync and then stored in a buffer then sent to pc.How do i sync up a pdm microphone and a icm IMU using stm32?What communication to use with the PDM mic, tha...
Hello, where do I download the AAC decoder ? Does it require a license ? How much does it cost ?
Sorry, Google Translate changed my previous post to Polish. That's probably why no one answered me.Now the post is correct. I'm creating a custom board using a used STM32H563VIT. Nice processor, but I can't understand how to create an Audo class, eve...
Hi.In X-CUBE-USB-AUDIO, You wrote:1. Does it mean that playback and recording can work simultaneously, and at different sampling rates? For example, playback at 44,1k, and recording at 96k?2. Does it mean that playback and recording may by governed b...
Hello,Please excuse the basic question, I am reading the datasheet of stm32f429ve trying to understand which pins I need to send data from the microcontroller to an audio codec using I2S. I understand the I2S interface requires three pins, with an op...
Hi! I've been following this tutorial to enter the world of audio dsp. The issue is that when I connect the board via USB, LD1 is always on (red) and I can hear a bunch of white noise at my output. When I power the board externally via 3V, LD1 starts...
Hello, I want to use X CUBE USB AUDIO examples in X CUBE IDE.After generating the binary code (without errors) and flashing the binary code via DFU, the card is not recognized as an audio device, I tried on all 4 projects. I unplugged USB, do reset, ...
Hello, I am a student. I want to use I2S through STM32L051K8U6N to complete the acquisition of the MP34DT04 sensor, but I have not found any information about libPDMFilter_CM4F_Keil.lib, keil library and IAR library similar to this. If it is convenie...
If there is an EVM that meets all or part of the following conditions, I would appreciate your recommendation. * I am looking for a possible EVM because I want to check whether a file that should not be played with SPDIF in due to license restriction...
Hello, I am using an open source voice-recognition software known as Picovoice. To use their library it must be passed a PCM signal at a certain rate with a specific number of samples per frame. I used CubeMX to enable the PDM2PCM library on the STM3...
