Other Parts Discussed in Thread: CC2640
Hello,
I have interfaced CC2640 to ADS7828 using I2C driver. I am using Ads7828 in external voltage reference mode with Ref out pin connected to Vdd (3.3V) but when I am applying constant 3.3V to one of the channels to get the reading in 8 bits. I am getting every alternate value correct. below is my reading for 3.3V.
I2C Initialized!

I am not to figure out the reason for this constant value of 15.
