Hi,
I'm trying for Wave PCM recording as described in http://www.vlsi.fi/fileadmin/software/V ... corder.pdf
Below give is the initialization code used,I'm able to write and read back correct values form the registers whereas the DREQ pin do not show any
transition in the oscilloscope and the recording is not starting(HADAT1 = 0 always) .
The plugin is loaded as described in the Application note.
