Hi Bobby
I have no idea at this stage. I have Neil Ungers EC3 which I installed =
as I thought it was an upgrade from my EC2 but =E2=80=98m not sure of =
the code version etc.
I was interested in the possibilities of the =E2=80=98knock=E2=80=99 =
detection but do not know if Tracy implemented this feature.
I can reprogram my EC2 (some years back - will need to reacquaint myself =
with MPLABS) but haven=E2=80=99t put time enough into working out MPLABS =
for the EC3 chips yet.

So I=E2=80=99ll reinstall the EC2 and go from there.

Cheers

Steve
