I am trying to figure out how to do pid speed control using the build hat serial protocol, using the built in pid on the build hat.
there are a couple of things i am struggling with
mode M1 is speed which is in units of PCT, which is percentage, but percentage of what?
also if you run the help command there is a command which is not in the datasheet the command is pid_diff the help output says
pid_diff <pidparams> : set current port to PID control mode with <pidparams> and differentiator on process variable
what does it mean by 'differentiator on process variable', does this mean that if the proccess variable is specified as absolute postion it will actually do pid on the rate of change of absolute postion?
any help on this would be greatly appreciated, i cant really find any info out there other than the data sheet and it just doesnt explain what i am asking about at all.
