Dear all!
I tried to connect my afe4490 evaluation board with the pulse oximetre, it worked yesterday,
but now, its led is giving buzzing sound, and even the pulse oximetre does not emit any light,
i check on the txp and the txn test point on the scope, and it does not give any result as i've got previous day.
Could it be that my evaluation board has short circuit?
Is there any way that i could do to fix this problem?
Best regards,
Stella
