Optical Encoder

- there are 2 kinds of optical encoder: Incremental and Absolute - Incremental: measuring change of angular position, not the actual position - Absolute: measuring the position relative to a reference position at any time - number of pulses of a rotation indicate the number of angular increments in one rotation in incremental encoding - ω(rpm) = f/N *60 where N is number of slots on an optical encoder -

Smallest but does a great part

Did you know that Avago Technologies is the one who made the smallest 3-channel reflective technology encoder? Well, with a size of 3.95 mm x 3.4 mm x 0.9562 mm, this reflective incremental encoder is designed ideally for high volume application. The AEDR-871x has digital outputs which is why it is suitable for printers, copiers, card readers, miniature camera modules, optometric equipments, and the likes.

How I wish companies like Xerox, Epson, Canon, Brother, and many others are using AEDR-871x encoders. I'm pretty sure this will yield more productivity with less maintenance and less cost. This component may be small, it's even the smallest of its kind, but it performs a great part. This device is truly a great space-saver.

Wired version is here

Since this library (AccelStepper) is nothing short of amazing, writing the code turned out to be quite a breeze.

I'm still no contestant for the most stylistically inclined coder so be warned. Still, I think I'm getting better at this...

Next stop - wireless which is quite messy. Previous prototype had values of up to 180 sent over Xbee; no problem for a simple byte sized Serial.write. This time I need 2 bytes and I'm going deeper into the bitwise operation. I wrote I kind of liked it, right? Now it seems to get back at me with a vengeance...

Anyway - here's the code...

People can be so great. Have you heard about bildr.org? You should visit this great blog if you find arduino interesting.

So what's my point?

Researching optical encoder, arduino and stepper, I came across bildr's tutorial "Rotary Encoders and Arduino". I figured out some things thanks to that post, and was left with some new  - more refined - questions. I happily posted my questions there, specifically wondering if there is a way to create a modified "knob sketch" using a stepper and an optical. Soon enough I was answered by Adam, who happens to be the founder of bildr, saying that this seems like an interesting query, and that my project seems interesting enough and well --- "awesome" -- so he'd gladly help. Is this great and awesome, or what? e mail correspondence ensued and I was delighted to learn of a library called AccelStepper that helped me get to the desired goal, as is visible in the video.

The code is fairly simple once you understand that steppers are so much different than servos. I admit I had to check, recheck, ask, research until I finally figured what the hell was going on there. But that's what friends are for, right? :)

I'm posting the code and finishing this with 3 important notes:

1. I had to push up the baud rate or else Serial.print delayed the hell out of the motor. Serial.print will be replaced with Serial.write for the Xbee, and so had to be checked early on.

2. Check out the void updateEncoder() function. This is the first time I understood what all the "bitwise operators" talk actually means, and I find it simply beautiful...

3. I will now proceed with the implementation of the various modes for the follow focus. I suspect I'll have some issues and problems along the way, but otherwise there would be no sense of accomplishment, right?
