@asheeshr In your sga_filter you have defined i as an uint8_t, but later assign it to be a negative number in a for-loop. This can be problematic...

See i=-SGA_MID.

uint64_t sum=0;
uint8_t SGA_MID = SGA_LENGTH/2;
uint8_t i;

for(i=1;i<SGA_LENGTH;i++)
{
history_SGA[i-1]=history_SGA[i];
}
history_SGA[SGA_LENGTH-1]=current_value;

for(i=-SGA_MID;i<=(SGA_MID);i++)
{  
sum+=history_SGA[i+SGA_MID]*sga_coefficients[SGA_INDEX][i+SGA_MID];
}
history_SGA[SGA_MID]=sum/normalization_value;
return history_SGA[SGA_MID];

}

@asheeshr great, code work for me.
