lcd dro

[Bruce Fairman]

hi, i have gotten the opendro lcd version to a demonstrable state. the pictures are stills but are an accurate sample. the operation of the dro is a bit different with direct access to the display line settings being the major change. each line can be configured for units, abs/inc, what is displayed (scale, tach, edge, etc). the edge snesors may be used wiht an axis or separately via an edge monitor pseudo axis. i will make a video of the operation shortly. also, as you can see, the buttons are now membranes switches and the case is aluminum.

Very nice job Bruce.

Bruce,

You certainly have made a lot of progress here but I have to wonder if this is still the best direction. The new pad computers that run Android seem like a great hardware platform at a price that is hard to beat. I also see that someone has put together a single channel analog plus 4 channel digital scope dongle that connects to an iPod touch or and iPad. So it appears that such an approach is possible.

Rick, i agree totally. i have an android tablet and a arduino uno for exactly that reason. i went to the maker's faire last weekend and arduino will have a development kit for android "accessories" coming out real soon. i am planning on using the arduino to operate the scales and other sensors and connecting via usb. basically, the tablet is a display for the dro running on arduino. this removes any realtime requirements from android.
the current effort is to provide the basis for existing and new dro550 users to move to an lcd display and to take advantage of the capabilities of the lcd (like using words, interactivity, more information all at once). 10 characters per line and five lines makes a big difference.

--Thanks,

Bruce,

I am delighted to hear you are that far along on the tablet + arduino path.

Now for a cold hard money question - given the low cost of a tablet, does it
made sense to modify a DRO550 or even a 350? Would it be better to just
reuse the scales and move on?
