BF AUDIO EZ-EXTENDER (with BF533/BF537 EZ-KIT)

Hello,

 

I'm trying to use the BF533 EZ-KIT with the Audio EZ-EXTENDER.

 

I have the Jumpers SPORT1_EN set and SPORT_SEL not set, so that I can use SPORT1 to communicate with the AD1938 codecs.

 

I don't understand where the processor should get the TFS1 (TSCLK1) signal from. As far as I can see, it is unconnected or connected to ground, when SPORT_SEL is not set ( SPORT_A connected to SPORT1 ).

 

It is the same with TFS0, when SPORT_SEL is set ( SPORT_A connected to SPORT0 ).

 

I try to figure out, how the Talkthrough_BF537_AudioEZExtender example works, but I see the same problem here.

(No possibilty to try out, I have no BF537 EZ-KIT)

 

Thank you for your help

 

cheers

 

Anselm
