976  Using Arduino / Motors, Mechanics, and Power / Re: record data from potentiometer & playback to servo on: March 23, 2012, 10:22:50 am
My goal is to make canned predefined movements where the motion is already smoothed or eased on the PC before it is loaded unto Arduino.  There are many PC apps that do this.  I have written a Sketch to make the steppers/servos move.  It's the in between part that I'm struggling with.  How to export the data into an array for the Sketch to use.  So far Excel is my friend.  Looking for an improvement...

Are parentheses needed?

((currAvg <= 1.05 * prevAvg) && (currAvg >= 0.95 * prevAvg))

I would put them in for readability sake.

Your >= and <= are backwards in the middle If.

Yes, I've got the signal strength working much further than 500'.  But there is too much data from video to send via XBee.  Is there a faster RF modem?  Or a way to compress the data down to 10K/sec?  320x240 pixels?  Slower frame rate?

I've tried all this before.  I've used a cheap camera to store photos.  A DSLR to store them.  600' of Cat5.  2.4ghz analog transmitter.  Seems like the limit for sending video cheaply is 600'.  If I could convert the video signal to slow data, I could send it with XBee further.  Any ideas?  I've got it working for still images from DSLR.  Thumbnail sized.

@Soffer- Yes, but we have not determined which software to use for motion easing.  Is there one you like best?  Can it export these values to a text file?

I have a similar problem.  I'm trying to get the data from 3-D animation software into the Sketch to move the servos.  I have the output movement working, but the process of loading it is tedious.  Maybe I should try pots?  I want the movement to look natural like a human body moving.

What you want is similar to my servo library.  It allows a script in the form of an array in memory.  It is designed for easing movements which change at least a few times per second.  The data is meant to come from animation software, but I have yet to figure out how to export and import properly.  How are you coming along?

What is the minimum bitrate for these?
Can you choose the bitrate?

How can I make it easier to find?  If you post on that topic it'll come to the top.

3.47v is too high?  I should be 3.0-3.2v for 2x AA batteries.

I have enough CPU resources to run at least 6 steppers at once, but not enough pins.  Try this it will allow you to run 2 steppers in the background leaving the processor free to do other things:

Plenty of extra resources!

Stupid question.  How do you install this into the IDE?
