Have you examined the Terrasic tutorials and sample projects? 

Another good place to start is searching these forums. There is a tonne of information on here, and most likely someone else has asked a similiar question.

hi  

thank you tnndesign for your reply... 

i have gone through demonstrations and with the help of those i am able to get audio from mic..  

i am able to change the sample rate and configure the CODEC 

but i am unable to write the data into on board FLASH i.e. 4MB flash.. 

as the flash data bus is bidirectional .. i may be missing something..
