    Re: newby looks for plc and motioncontrollers

    It is an absolute waste of time and effort. If you think about it for 2 seconds, this is the most complicated piece of garbage to do this job.

    You want analog input with no wear? Why don't you use a hall effect pot... ?

    Seriously, this guy buys an already expensive encoder, buys a microcontroller and writes firmware for decoding, pulses 2 pieces of 4bit counter IC's cascaded, which outputs analog voltage through an 8bit R2R?

    I mean, WOW. You loose 90% of your accuracy while spending multiple amount of time and money on it.

    Yes, you are completely right. The hall effect is the best way. Thanks for reply this post.
