Hello everyone,I'm working with an STM32WB5MMG module (STM32WBxx Series) and I'm looking to process the information coming from a digital MEMS microphone.I saw online that a PDM2PCM library existed at STM and I want to use it I red that a few years a...
Voice is heard through the codec chip, but the noise is severe.There is no noise when you listen to the voice from the PC through the USB output.I don't know if the SAI setting on the Central is wrong or the codec chip setting is wrong. If you playba...
I've seen that it's support Bluetooth 5.2 which added LE Audio feature.Is it possible to make SSTM32WB55-based sound device (i.e. BLE to 3.5 mm jack converter)?And how if so?
Situation - I'm combining code examples from the STM32WB Opus Library code, with that of the Echo Cancellation (AEC) Function Pack. Using the code base to have support for a microphone, speaker, and Bluetooth. When implementing the code for the CCA01...
We want to transmit audio over Bluetooth.We are new to audio and Bluetooth. We have got P-nucleo-WB55 board for Bluetooth and ST EVAL MIC007V1 sensor for digital audio.Can anybody guide us with an example project using I2S.Thanking in advance.
Hello,With the Nucleo-WB55 evaluation kit. We plugged in a CODEC to play audio.For this we need an audio player, but we cannot find an audio player provided by ST for the STM32WB55.Can you provide me with a link if there is one?Is it possible to impl...
The question is how do I connect the output of the pdm and how do I connect the input of the clock to the sensorThis is the sensorsThis is the mcu chip (stm32wb55cgu) Thank you for your supportefiehrman@gmail.com
Hi all,We are using stm32 PDM to PCM library to convert PDM mic data into PCM data. On that we had an option to control the mic gain from -12db to 51db as mentioned in data sheet.So we try to increase the db level, But we cannot able to increase the ...
Hi there,We purchased STM32WB5M-DK for our project. In STM32WB5M, We have only one SAI Interface. We connected PDM Microphone (MP34DT01-M) on SAI1 A. I want to play the audio signal with speaker through speaker amplifier. I'm using TAS2770 speaker am...
