Problem is more discussed in following thread:

I think fix is quite obvious, generator should produce just uint8 numbers.

Thanks,
Martin

Good morning, 
GCC 5.1 is now released and the check/error "narrowing conversion" is still 
here.
I would vote like Martin to fix the generator. 
Kindly
WT.

riesa@, any chance we could get the generator code checked in and start 
iterating on it? Issue 33 is tracking that.
