C2000 coding using simulink

the changes are not made in the real time in the ADC output, only after stopping the changes are made in the memory blks:

try graph functionality of CCS to visualize real-time changes.

I want to compare 2 ADC signals, for that which simulink blk should I use?????:

compare block of simulink library. give output of channels to its' input port.

I want to multiply 2 ADC signals too:

use product block or dedicated TI block for multiplication.

how I have to configure the constant block to match the data types and multiply:

there is functionality to set data type of output in ADC block. match it with data type of constant block.

yeah it really solved my problem of real time......Now I want to compare the 2 adc values and based on the condition i.e. if true then GPIO1 blinks otherwise no change in GPIO output....For this I have used a subtractor blk from simulink iibrary , then a mod to remove any negative result, then to comparison blk which compares with a constant, then its output is given to the and gate and this gate is recieving its other input from the different blocks in the same way as discussed...Then the AND gate output is given to data conversion to get int8 output and then this given to GPIO output blk....On running the code I'm not getting the desired results....I m attaching the photo of my simulink model , Pls help me out in this..Thanks
