New Head Unit....

jsclownfish · Post by **jsclownfish** » Sat Jan 12, 2013 12:03 pm

So, a quick update on the ezLCD... I haven't had a lot of time to play with it, but I think it can work depending on what you want to do. I am by no means a programmer, so I'm sure someone more adept could make it do lots of things.

I've just worked on having it display data from the main and it seems to be working. I haven't had really tried to make the touchscreen communicate back. I've found the prepared widgets (buttons, sliders, etc) are a bit wonky to work with.

Anyway, here is what it looks like when you order it....

and here is my first demo screen hooked up to my RA...

I'll be playing with some buttons and stuff soon.

very cool pictures. Looking good.

How are you attaching that to the head unit? As an expansion through USB? or TTL?

I use an I2C connection with the USB. I have a USB cable with the lines split out on one end. I then connect it to the Arduino board on the ArLCD. The I2C needs a couple pull up resistors so I have it on a small breadboard for testing.

I know I have been eyeballing this Touchscreen LCD

http://www.sainsmart.com/arduino-compat ... -2560.html

There is a sheild to fit it directly to a Arduino Mega 2560 as well. I think The Display with the sheild can be found on ebay for about $30

It's been calling my name...

Just be careful with level shift....
That board does not have one.
I'm 99% confident that the LCD module is 3.3V.
I use similar screens and they are all 3.3V. If your Mega is 3.3V, then you are fine.

Here is the same Display on ebay with the sheild and even a Sainsmart clone of an Arduino 2560 Mega all for about $50

I came so very very close to purchasing this package.

http://www.ebay.com/itm/SainSmart-Mega2 ... 3f1a0ab450

I did buy one but with the more common blue 2 line LCD with the up/down/L/R/Enter buttons. Cant remember the LCD model number but it's a common one used in Arduino projects. Should arrive any day now.

I spent the good part of the weekend working on this "ezLCD" system to try and accomplish three things:
1) receiving info from the main to display on a bigger LCD
2) control the relays from the touch screen
3) alternate between screens to accomplish 1&2

Seems like it would be straigthforward from the system libraries and the "widgets", but I had a tough time getting them to work appropriately and had to litter the code with delay steps to allow things to display correctly. This causes things to show correctly, but they don't always load as you would expect and it requires you to hold buttons 2 or 3 seconds before you see the activity. I'm guessing this has to do with the speed the LCD communicates with the Arduino board. I also had to add back in code for text display, clock, etc that is already in the RA LCD library but not in this LCD. Nevertheless, I did eventually get it to work

, but I wouldn't say it is robust. Here is a video link of how it looks....(nevermind the football in the background, I was multitasking

)

If you're curious, here is what the code I put together looks like for the ezLCD. I'll admit I have no idea why some of the delays work, I just started adding them in places until it displayed correctly.

I need to get back to it.

I kinda put in on the back burner as Roberto was moving forward on an LCD extension.

Hey thats cool. This serves as an inspiration for the next Generation Ra controllers.
The only problem here is if your hands get wet or dirty and you accidentally touch it. I wonder if this touch LCD screen is like the apple ipad screens really heavy duty.

I'm looking into doing a touch screen as well. Right now I'm getting all the required pieces needed to prototype a stackable shield for the mega2560. Thought about using a 3.2" tft I got a 7" tft as well. I figured there would be more room on the 7" to display a lot of parameters, but would still try the 3.2" tft to display these other parameters on different screens. Setup menu would be basic time, pH calibration, feed, water change modes as well as clearing any flags. Will take a bit with working 12hr days.

Excited for a new touch screen for my RA controller.

The joystick has been ok but I can already retire them. Now
that 1 of my RA controller joystick stop working properly.
I cannot scroll anymore to the right. Despite the repair.
Im just waiting for the new Touch Screen LCD controller
to be available.

This is my guess eventually in time the other RA joystick will
break down and you will want to have the new LCD touch screen
ready if not as a back up with you.

The important thing is the LCD screen should be robust.
specially near seawater.

Anyone know when the RA LCD touch screen will be ready.

I could be wrong but I don't think it's going to happen. Few people have used tablets instead, considering they are so cheap now.

I believe there are prototype touch screens in the wild, but given the cost a cheap, dedicated 7" Android tablet running the RA app is a more reasonable way to go. I've done this for a few years now and it works great.

Robert I seen u said you can run a secondary screen with Adriano shield or something like that. I would like to have a larger screen but don't want it to run from wifi cud of the update Intervals . And would like live feed on it and direct interface on my phone sometimes on the app it will lag or error sometimes and then I gotta do it again.

A cheap tablet or custom LCD touch screen would be cool but have no idea what route to take and if some help form from someone to set up a secondary larger touch screen would be great

A cheap android tablet running the ReefAngel UApp or Binder's app.. doesn't have to rely on the cloud..

troylong45 · Post by **troylong45** » Tue Sep 06, 2016 1:00 pm

It don't work properly for me same on uapp (home ipxxxxxxxx:2000/wifi) and the Android app on home . It's to delayed and errors sometimes while its loading. So i think hard wired is the way I have to go.

lnevo · Post by **lnevo** » Tue Sep 06, 2016 7:12 pm

Thats not uapp. Try downloading the native version of the uapp, not the /wifi, that one is buggy.

troylong45 · Post by **troylong45** » Tue Sep 06, 2016 9:40 pm

Where do i find that

Thanks Lee and cosmith71, I got it to download it doenst seem to be a live feed only if u hit refresh . The fuction is there but not the constant up to date feed. So that won't really wrok for me I'll probably have to search some more on if anyone has done a Tutorial on a touch screen and or bigger screen.

lnevo · Post by **lnevo** » Fri Sep 09, 2016 4:35 am

Roberto, can we add auto refresh in the uapp?

rimai · Post by **rimai** » Fri Sep 09, 2016 12:23 pm

Yeah, but the cloud server would take care of this and provide a live stream of data without the need of refresh.
You will just have to wait a little more for the cloud server to be a reality
