Hi!
I want to interface a current sensor ADS712 with 16F877A.It outputs 2.61V with 0A and rises as 66mV/A.I am using AtoD with 10 bit res & using 2.61 as -Vref and 5 as +Vref. Now how do I scale the voltage to current conversion.I used different formulas but result is far from accurate.Using 0V as -Vref makes it even more difficult to scale the voltage to current conversion.
any ideas.
