Expansion interface in BF533 kit lite - mall...@yahoo.co.in - Sep 21 8:41:26 2007



Hi! 

Iam having some problem with expansion interface in BF533EZkit 

Actually iam testing Video encoder kit(our own encoder kit) with BF533 expansion
interface........So, from the BF533 kit iam taking all ppi outputs(PPI0-7) and iam connecting
to my video encoder kits ppi inputs and similarly all the other pins also............... 

I have taken in board OSC of 27 MHZ(in the video encoder board) from there only iam giving
signals to both the encoder and the ppi.......... 

but,iam not getting any output in the video encoder kit...... 
I have tested the kit(video encoder kit all the connections properly)
..................................... 

I want to know whether the ppi is sending the signals or not in the ezkit lite... 
how would i know ???????????????? 
(it is running in 27Mhz.... ) 

and also i want to know whether the video encoder is reset or not... 

Before reset and after reset can we find any difference in the video encoder externally...(like
supply inputs and GND....)........... 

PLease help............ 
thank u inadwance
