 		 #125327 - Assembler is dead
Responding to: ???'s previous message

I would not (and did not) use flaoting point for a PID.

32 bit fixed is just fine for many PID uses.
I am not sure that "square roots and Taylor's power series expansions" are needed for PID. As I recall, Addition and Multiplication mostly, and a divide or two.



Hi Neil,

Who said anything about using floating point for for PID??, I'm going to either words or integers i.e., for increased speed.If I can squeeze 32 PID loops out one chip all the better.
