Posted on June 01, 2013 at 13:10 Hi all. I got my first f4-discovery some day ago from my robotics and embedded systems professor. I wanted to try some basic audio manipulation, but it turned out i can even output some synthetic wave fro...
Posted on May 07, 2013 at 03:07I'm trying to create a project where I send an audio file from a computer to my STM32F4-Discovery board via USART and play the file. I have successfully run a USART example where a character is sent to the F4 board and...
Posted on March 23, 2013 at 21:28Hi all. I try to run audiopayback and record demo on F4 discovery board. When i upload precompiled binary (internal Flash mode) i hear from speakers 5 sec audio sample. Sound is not ''crystal clear'' but i think is c...
Posted on September 10, 2012 at 22:37I have an application where I have a digital mic/codec combination transmitting PCM 16-bit samples over I2S to an STM32F217 at 16kSps (Phillips I2S standard). I am trying to use DMA to capture this audio stream, ...
Posted on November 04, 2012 at 20:08Hi,I want to do a very simple project using FreeRTOS alongside with STM32F4-Discovery. I want to create a task to read from a microphone, another one will filter the mic's data and a final task would output the fi...
Posted on October 20, 2012 at 10:24Hi !I'm talking about stm32f4_discovery_audio_codec.c v1.1.0 for CS43L22 .It is used in the record & playback audio demo and you can find it in the ''utilities'' folder.I've struggled a lot to make the circular buf...
Posted on August 09, 2012 at 15:50Hi,I am trying to use beep generator function provided by CS43L22 on STM32F4 DISCOVERY.I want to generate continuous beep and listen that on headphone, Here's the code that I've tried for that. I got no error while ...
Posted on May 25, 2012 at 15:55 Hi guys ! Firstly - hello to everyone ! I have some questions. I am trying to make a project on STM32F407VG that would transfer data from microphone to the headphones through a filter. I am totally new to t...
