Hello Mike,
I want one clarification.
While reading first time I am configuring ch0 to 0x08(that is Vin1-Vin0)
here it is okay But for next read I am configuring ch0 to 0x1A(that is Vin3-Vin2), when i am reading this it is giving Vin1-Vin0 value, If read again with same configuration I getting Vin3-Vin2 value.
Tell me how to come out from this problem.
