31  Using Arduino / Displays / Vizic SmartGPU2 480X320 LCD w/ Audio. Uno y Due compatible. on: December 19, 2013, 02:56:18 pm
Folks,
I received an email from Vizic about their newest Smart LCD.
(I have used the original 2.4" 320X240 model successfully on the UNO and found it so easy to work with).

This SmartGPU2 is interesting for a couple of different reasons:
1. 4280X320 is a decent resolution.
2. Has a  Touch Screen.
3. Has a SDCard interface that supports 32bit fat long file names (display .jpg and .bmp and play .vid and .wav)
4. Has an audio controller with a built in 3.5 Jack or you can use pins.
5. Has a configurable pwn backlight (for dimming).
6. The libraries support geometries and primitives similar to Henning LCD libraries
7 3.3v and 5v I/O compatible.
8 Uses the Arduino serial interface, simply passing commands to the onboard host controller.
9 Host controller is an Atmel ARM Cortex 3M processor (similar to DUE), that does the heavy lifting for the file system, video, audio and touch.
10 $125 USD Price.

The gotcha, straight away is the Price. But there are a few cases where this is not a bad deal. Particularly in an advanced application where one was considering seperating UI elements from Control elements.... ei... two independent Arduinos....linked together.  A cheap ColdTears LCD 3.5" is $33. A Shield is $10, A cheap audio solution is $5, a cheap Arduino Mega clone is $20. So you're up to $70 already, but it's a hodge podge of parts that you must integrate. If your building a one off or a few protypes... the extra $50 is probably not a bad deal for the integration and simplification. I love the idea of just using a few pins on one DUE and that's it.

I've written the company and asked them if they are considering adopting a 5" 800X480 panel and applying the entire feature set of their SmartGPU2 3.5" 480X3420LCD model.

Has anyone used this product?

Paul,
I was hoping this idea would get more traction.

I've had so much difficulty logging into the fórums, I couldn't put up any helpful info. So frustrating.

Anyway, I've got some solar cells and lithium batteries coming. (logistics are challenging now that I live deeper in Mexico, in the mountains). Some ítems landed in my mailbox in Tucson and a visiting friend is hauling them down on Monday (a 10 hour trip - one way). I've determined that the hobby project I'm working on needs to go off the grid. That means power supply and conservation have just become big priorities.

Tom,
This is getting ugly.
I haven't been able to log onto Arduino in probably a week.
Today, I tried for more tan an hour.

Here is what did it.. I followed your directions... but I did not close All explorer Windows.

I opened a Blank Tab... Then I closed the Arduino Tab (the one I did the F12 trick following a login).
After taht, I typed in www.arduino.cc on the Blank Tab... noted I was still logged in.
Selected Fórums... and it went... without the Token garbage.

Exassperating. This needs to be fixed. What worked today... was not what I was doing a week ago.

Tom,
Exactly. That is precisely what is necessary with Internet Explorer 11. Your step by step approach is much better than my "just do this" advice. Thank you for taking the time to help folks out by eliminating so much of the trial and error frustration.

Folks,
I'd like to recommend a new Topic under the Using Arduino Section of the Arduino Fórums.

Energy Supply and Conservation.
This could cover every thing from Solar and Battery Technology, as well as Energy Conservation methods for your Microcontrollers and Shields. We could cover Sleep methods, Wake Methods, etc... Disabling/Enabling functionality when unneeded, etc...

This topic needs specific focus, especially as we begin to network our Arduinos to the outside world or place them in remote locations. We can't be running wall warts everywhere, nor constantly changing batteries. All of us need to borrow ideas from one another specific to supplying and conserving energy. Hardware and Software ideas alike can be shared.

I would put it right between General Electronics and Microcontrollers.

That's just an incredible piece of work! Thanks for sharing.

no. when I take the token off.... it only returns.

F12, Clear Cookies for Domain is what Works for me...
Then I have to open the fórum up in a NEW TAB and close the former tab.

This 'token' issue is has become so bad it's preventing me from participating on the fórums.

I've tried logging on for 3 days now.  Today, I suspect the barometric pressure, solar orbit, moon phase and the interwebs were fully aligned, permitting me to succesfully login and Access the fórums. Wow.

In Win 7 with Internet Explorer, this is what I do:

1. Sign in.... selecting Show All Content.
2. Go to Fórums.... wait for the token garbage.
3. Hit F12... Go to Network section of Options.... Clear Browser Cache only... Don't delete cookies or anything else... just select Clear Browser Cache.
4. Open a NEW instance of Internet Explorer as a new page (not a new tab...but a new page).
5. Go arduino...  GO to Fórums... You should be there.

I think.... I tried so many different things today... but I think that's the combo that finally yielded.

I will respond to Paul's post.

He is correct. The problem has long persisted. It existed before the site upgrade.

Furthermore, I've had it on XP machines running Explorer 8... all the way to my Win7 machine running Explorer 11.

I was commenting on the fact that with Explorer 11 it just seems harder to put right..... I promised to document how I loggin... but It's so difficult.. I can't remember what steps actually helped me return to the Fórums...LOGGED IN.  I'll do it next time.

Upgraded to IExplorer 11... it's even harder... The F12 Debugger is much more cryptic (has the 'Modern UI' interface).

I'll document what I do...the next time I log-in...

I offer the following from Graham Hess (Signs):

"For them, the situation isn't fifty-fifty. Could be bad, could be good. But deep down, they feel that whatever happens, they're on their own. And that fills them with fear."

"There is no-one watching out for us. We are all on our own."

The best part of the F12 solution is that it clears all sesión cookies for any other websites I might be using. Of course I don't mind because I enjoy retyping all of my user/password combos for sessions I have on other websites.

set sarcasm = OFF;

I wouldn't do anything to prevent  use of HSMCI.  I was very disappointed with Due.
All of these sound great:

I know it's an older comment. Could you elaborate on what disappoints you specifically with DUE?

I went to modify the post...and deleted it by mistake.  stupid user trick (we used to call it the ID 10T error).  Oh well...

Instead of retypeing the whole thing... I just went over to Hennings site... made a donation.. and told him thanks for his work on the UTFT stuff.

Lakes,
Thanks for the reference. I just pre-ordered that book.

I'm a bit like MechFX..... the curse of being an enabler that has much expected of him...
