hi andy,
i want some information regarding the detection of negative slope when a Ni-Cd battery charger is charging at 880mA.
I am using 4Ah battery.
Actually i wrote the logic as
vmax<=vmin + 1
where vmax is maximum reading in an array
and vmin is the minimum reading in an array..
but i am not able to sense the negative slope after a long period... instead of that i am able to get -ve slope quickly whenever the current is switching to 880mA eventhough the battery is a fully discharged one.
regards
rao
