Hello friends
I have used ads7924 before with my tm4c129dncpdt and their I was using Manual scan mode. Now I am using EFM32LG controller for this IC. This are the step which I am following
Well I have seen one error and shorted DVDD with AVDD but now I have connected it but still the issue is same so I removed r70 and c64 as per the suggestion from the previous post but still the issue remains the same. I have tried reading in manual single scan mode only that channel but still the issue.
1) Sending Awake mode command
2) Disabling the alarm (default values)
3) Configuring Intrconfig as busy
4) And acqusition time as default (6 micro sec).
5) Sending Manual scan mode command 0xC8.
and in a cyclic loop of 2 sec interval I am reading the four channel values and at the end once again sending the manual scan mode command.
I am measuring the voltage near chnl1 the volatage is steady and not varying but the values which I am reading is varying 0.7 volts randomly.This is with respective to all the channels.
If I am missing something suggest me.

Harish
