LAUNCHXL-F28069M: Help with programing ADC read program using Simulink

Part Number: LAUNCHXL-F28069M
Other Parts Discussed in Thread: C2000WARE

Hello E2E community!

I have been trying to use Simulink to read the voltage sensor data output through the ADC pin on the Microcontroller board. However, there are a lot of issues I fail to address. If anyone has any idea on how to resolve these problems, please guide me through. 

Problem : 
1. Starting simulation at different times gives different values without changing any thing in the setup. As you can see in the attached video, I have to stop and start simulation file multiple times before I get the right data from the port. I want the program to perform exactly the same way all the time if there is no change in hardware/program setup. How do I ensure this using simulink?

2. The noise on the ADC is very high. I need to extract the DC value from the signal shown in the scope. I have tried using IIR filter, Moving average as well as Running Mean. But none of them give the proper value. There is always +-2V error in the values read. 


I look forward to your help and guidance. 
Thank you!

Regards, 
Prashant
