2007-08-06 17:07:13     AD1938 or AD1939 Driver Availability (4 ADC, 8 DAC Codec)

Steve Strobel (UNITED STATES)

Message: 42569    I am looking for a driver for the AD1938 or AD1939 codec.  I am using the a custom BF537 board that is very similar to the BF537 Stamp.  I have seen references to a driver on other mailing lists, but have not been able to track down the source for it.  Any pointers greatly appreciated.

Driver for 1836 - which I think is pretty close - exists in the dist. Did you have a look at this one?

 

Thanks

Message: 42577    I did look at it, and it does seem pretty close.  The datasheets for the AD1836 and AD1938 are very similar (other than the extra two DAC outputs on the AD1938) until you get to the control register definitions, and then there are some significant differences.  I may have to work through those, but I was hoping someone else already had.

 

Thanks,

Steve
