What is a good approach to measure the time it takes to receive each I2S sample when using DMA from a CODEC into my STMF446 when using interrupt callbacks?

2021-11-27
Hi, in my current audio processing set up I have a CODEC set as master connected to my STM32F446RE (slave). The current configuration utilizes I2S DMA interrupt callbacks to handle the input and processing of these samples received. The CODEC receive...

Could a running I2S DMA function affect my encoder interrupt service routine?

2021-11-09
I have two things in code running simultaneously:1) A CODEC using I2S with DMA is initialized and started as soon as the code is compiled and flashed.2) I have an interrupt for my encoder which is used for selecting things from a menu.The problem I a...

How to properly read in digital audio data coming out of a codec's ADC using I2S protocol?

2021-10-27
I am using a STM32F4 MCU, currently prototyping on a Nucleo-F446RE. I have a PCM3060 audio CODEC to do the analog to digital conversion. I am attempting to use the I2S protocol in order to interface the stm32 chip with the CODEC to process real time ...

I am trying to interface a STM32F446RCt6 with a PCM3060PW Codec through I2S in order to do some DSP for an incoming guitar signal. Has anyone here experimented with this Codec in the past and could point me in the right direction for documentation?

Problem reading analog values from 3 different potentiometers on STM32 Nucleo-F446RE

2021-10-19
I have been trying to use three pots as dials for a guitar effects pedal project. Their purpose is to simply read the voltage from 0 - 3.3V and with some scaling (to turn the raw readings into 0-100 values) in the code to store these 3 values inside ...
