We're developing a product on the ADE9000 and using the zero cross detection on V1. The output is delayed by about 2.5ms if we use the daughter board on the dev kit. Any ideas of where it could be coming from?
Without the daughter board its perfect
EVAL-ADE9000 include the eval board (with ADE9000) and the SDP-B (with BF527). There is no daughter board. Could you please clarify me which set-up are you using?
Thanks for the reply.
We are using the 'standard' set up - EVAL-ADE900 + EVAL-SDP-CBIZ as
described in the User Guide for the ADE 9000 EBZ kit.
If we set the 9000 up using our own micro by writing to the registers
ourselves all is fine but when the we use the CBIZ to do it there's a
2.5ms delay on the zero crossing signals.
Its a bit of a puzzle - maybe we're doing something wrong but I've been
through all the registers and they seem fine.
Thanks for your help.
