I am trying to figure out a way to use the Arduino Diecimila with an LCD touch screen as the input for a motor controller. The Arduino would control an industrial PM servo motor. I was if anyone had any information on which touch screens to use and how to interface them. The screen would have to be at least 4'. Also wondering if there is any information on controlling an industrial servo motor through an amplifer with the board. The examples I have found are for motors that are way too small.
Lol, if you're trying to interface a 4' touchscreen to an arduino I think you need to do some more research before you ask "how do I do it?". If you mean 4", that's a different story. However, most likely you will not be able to interface an arduino with a color LCD of any kind, and you will be stuck with monochrome. If you want color, you're gonna need to bump up to a 32 bit micro. And it also depends what kind of touchscreen it is. For example, resistive touch can be hooked right into the arduino while capacitive touch needs external components.
Yeah, I don't want a 4 foot screen it is obviosly a typo. I have never seen a screen measured if feet. Have you?
Do you guys know if any attachments for screens. Nothing too expensive please. Also do you know if the arduino can run an industrial amplifier. The ampliefer would be for running motors with voltage up to about 40 or 45 V. Thanks a lot
I found a cheap 4.3" touchscreen ($18 US plus shipping) at 4.3" Touchscreen LCDs. The info on the page is for the Parallax Propeller Microcontroller. He carries a breakout board to go with it that permits the use of 6 bit color. There is also a reference to a 24 bit color breakout board. Both have I2C interface for the touchscreen part. It may be able to interface with the Arduino.
