Looking for ideas to eliminate chattering of my relays that are activated depending on the ADvalue that is read from the analog input.
The Analog value is filtered through DT_Analog module (Analog oversampling to 12 bits).
But on the decision point, relays are chattering on/off as the analog value is slow changing.
Code:
gosub getADC
'ADvalue=abs (ADvalue-818)
if ADvalue < upper then
relay.0=1
else
relay.0=0
endif
if ADvalue < mid_upper then
relay.1=1
else
relay.1=0
endif
if ADvalue < mid then
relay.2=1
else
relay.2=0
endif
if ADvalue < mid_lower then
relay.3=1
else
relay.3=0
endif
if ADvalue < lower then
relay.4=1
else
relay.4=0
endif
Any ideas?
