Posted on May 02, 2013 at 17:40Does anybody have a good ap note or direction for incorporating software compression on an audio stream? I'm using the discovery board[STM32F4] to record the audio[8KHz 16Bit] and would like to send over a wireless lin...
Posted on April 23, 2013 at 01:28When executing the audio clip from flash[const defined location as in the example project] the audio file plays fine, but if I remove the ''const'' as to allocate ram for the audio clip, I get only a small block of w...
Posted on April 18, 2013 at 11:04Hi,I'm using an stm32f4 on a PCB and suddenly it became extremely hot. The strange thing is that it still worked, but there was an extremely (relatively) high current running through the circuit. I've removed the stm...
