Thx

SX2/CN2 Tachometer Discussion / Re: Receiving "communication Error 1" when trying to use the Arduino Sketch

Hi,
 first of all, thank for taking care to document everything about this tach.

I have a mill bought in May 2015, and think I have got the one with the protocol change.
I have wired up an arduino and I started with "communication error 1".
I have then added some debug lines and I have noticed that the cycle usually get 69 bits and sometimes also 70.
This obviously lead to the communication error.

Here the sample from the serial output I have added on the second part of the cycle ( when it get the error )
( the first number is "packet_bits_pos"  the last two bits gets from the 69 end 70 ( when it's there ) bits )
( This are collected with the spindle stopped )

Now from the spindle rotating:

When the spindle is rotating, sometimes I get a "Communication error 2" but haven't still got some output from there. I'll do this this evening.

I'm waiting to receive a SALEAE clone ( I know, I should have bought the original but being that I think I will use it just few times.... ) and as soosn as I can get it up and runinng I will take some snapshot for you.
