76  Products / Arduino Due / Re: [Finally a working EMAC library] Connecting an Ethernet PHY to Arduino Due on: April 02, 2013, 04:50:14 pm
Good news Wilfredo.

Two Taijiuinos have been sent to Oz, so that Paul & Rob can continue validation with other PHYs... as they develop their DUE work alike.

However, I do not know how to source the Ethernet PHYs that you folks are developing with.  I still have three Taijiuinos in my possession and I'd like to give it a try too.

I have one PHY in my possession,
LCTech ENC28J60 Network Module
here is the info:
http://www.lctech-inc.com/Hardware/Detail.aspx?id=588fbc2e-ecc1-4013-ac35-69bc83bda1fb
On-board ENC28J60-I/SO chip.
On-board 25MHZ crystal.
On-board HR91105A network interface.
3.3V power supply pin.
Size: 56(mm) x34(mm).

Is anyone doing any work with this one?
77  Using Arduino / Displays / Re: Loading Image into an 7" TFT LCD from SD Card on: March 29, 2013, 06:22:00 pm
Moderators... Please remove this Thread for Daniel and I.  We were working together on it (we both own 5" and 7" LCDs).  Unfortunatel, I purchased the wrong LCDs for both of us..... inadvertently I purchased the version without the Font IC, which also has the Flash for the internal image storage.

It will cause confusion if this remains....as it is simply a purchasing error on our part.

Working further with the 3.2" and 3.5" CTE LCDS on the CTE Shields.... finding they are backwards, rotated and mirrored...
Daniel saw the same thing..and posted his findings on this other thread in the Displays section...

http://arduino.cc/forum/index.php/topic,157068.msg1177939.html#new

The demos worked...
Then we went to develop our own stuff...and found the coordinates were broken it was plotting rectangles and text in the opposite corner.  the demo looked good because I had the displays rotated 180 deg...

I will no longer comment on these two items here...but put the comments in Daniel's very specific thread.
79  Using Arduino / Displays / Re: Reverse Coordinates DUE w/ CTE Shield on CTE 3.5" 480x320 R61581 LCD on: March 29, 2013, 05:53:12 pm
I am having the same problem on the 3.2".  Daniel and I are teaming up to work on this issue together.  We have the same shields, LCDs, DUEs...and unfortunately..the same exact issues...

Very frustrating to purchase products, download their demos, their libraries... then run them and the images are flipped, mirrored, rotated 180 deg. text is mirrored...bitmaps are not... etc.. etc... touchscreen counts down backwards, etc...

Is there anyone using these 3.2" and 3.5" ColdTears products where they just work?

Trying to determine if Daniel and I have a bad batch (we ordered them together).

Paul,
Let's get a Taiji-uino and it's programmer over to you. I'm all for dividing the workload and splitting expenses.
email me at odwyerpw@sonoratechnical.com with shipping info.
Peter

At some point, when you're ready just send it over my way. A sort of rob Paul to pay back Peter.
81  Products / Arduino Due / Re: Touch using CTE shield on DUE plus maybe SD card/SD card on TFT on: March 28, 2013, 04:13:21 pm
I've already sent an email off to the folks asking them just that.
82  Products / Arduino Due / Re: Touch using CTE shield on DUE plus maybe SD card/SD card on TFT on: March 28, 2013, 02:25:46 pm
OK,
Found the source of my issues... I purchased the WRONG SSD1963 LCD panels.
Cold Tears Electronics offers the 5" & 7" SSD1963 800X480 LCDs in TWO versions... With Font IC and Without. Unfortunately, I have both of them without the IC, hence the demos show garbage for the text and bitmap portions. I've ordered the correct versions now...

However, with the CTE shield, I had great success with two others offered by Cold Tears Electronics:
3.5" 480X320 R61581 LCD Controller & ADS7843 compatible Touch Controller w/ Font IC
3.2" 320X240 SSD1298 LCD Controller &  ADS7843 compatible Touch Controller w/ Font IC

We used their modified versions of the Utouch & UTFT libraries (which probably precludes adopting everyone's high speed modifications they are developing for Hennings Libraries).

I found performance acceptable.  Touch Screen Worked. It's a little weird using a utility to load from the SDCard into the Built-In Flash...and then your code calls your images from the Flash by Number. That means you can't easily just stick new images on and SD Card and modify your sketch. Instead you have a finite number of images to work with. That's ok. My preference is the 480 as the visual quality is very good.

The other odd thing is for the 3.5" screen with a resolution of 480X320, the Touch Screen has a resolution of 509X264. For the 3.2" screen with a resolution of 320X240, the touch screen had the same resolution of 509X264. So in my code I will resolve the difference by scaling the data I receive from the touch controller to match my graphical coordinates:
Screen Res X = 480 - (Touch Res X * 0.9375)
Screen Res Y = (Touch Res Y * 1.2121)
Resolving it this way should help with deciding what object (slider, button, toggle) was manipulated by the user. Without re-inventing the wheel I'll need to see how some folks went about creating an object oriented approach.

We are experimenting with 5 Due's (Arduino y TAIJIUINO varieties) at the moment. While I am enjoying the freedom of multiple UARTs and Allot of I/O... well, I'm growing frustrated getting LCD touch screens, SDfat and I2C working acceptably. (I bet we have 9 different LCD panels ranging from 2.4" to 7").  I haven't even begun with Ethernet...nor do I have the technical expertise and capabilities you all have. It's frustrating because I want to stop messing around with getting the prototyping platform (DUE) operational and just move on to designing and building my proof of concepts. Admittedly the stuff I am trying with DUE is magnitudes more difficult than what I've done with Uno and Mini. I need local user interface (lcd/sdfat), remote user interface (web/Ethernet), local I/O (done! finding hardware debounce was awesome) and remote I/O (I2C) operational.

That said..if you all (GreyNomad, Wallaby and Pallisar) identify a number of PHYs you want to try.... just direct me to where they can be purchased in quantity and at good prices...and I will donate them to the cause... I'll gather a mess of them together and then get them shipped to Oz and Venezuela. (I live in Mexico but I get up to Arizona, USA allot). I'll send you multiples so that you can burn a few of them up at will. Sorry, guys, that is the best I can do stepping up to the plate to help you guys with the effort.

I just received my 5" 800X480 SSD1963 TFT from CT. It has a 40pin header.
I am using it on the 40 pin header of the CTE shield for DUE.
Going to try getting SDFat, Touch and all of the Demos working on it.

85  Using Arduino / Microcontrollers / Re: Using extra pin as digital output on: March 18, 2013, 11:22:09 pm
Thanks for this info. I have a project on an Arduino Pro Mini where I was 2 pins short (everyone appreciates an audible alarm and then a button to silence/acknowledge it!).
Now I will repurpose all 6 of the analog inputs as digital inputs and leave pins 1 & 2 available for serial communications in the future (Should I need it). That's puts me up 2 pins now!
I won't even mess with the two 'bonus' analog pins in the center of the board.

What you can do with the Arduino that is very useful is to receive signals from these probes/circuits and make them available for display, data archiving and control.

There are a number of folks doing things with these probes to control their aquariums. Just search on Aquariums. I've seen handmade ph, temperature and conductivity probes. I recall one user that has even custom built PH, ORP and Conductivity Shields. (search Arduarium)

BTW, Salinity can be calculated from a conductivity probe.  In fact, Conductivity, Salinity and Total Dessolved Solids can be derived together.

Atlas Scientific has nice stuff (I am using it for two projects that involve Arduino for prototyping). It is expensive, but is pretty much system agnostic (they standardized on serial communications to interface with their sensor/circuitboard combos.)

I agree with westfly...

As a new user to Arduino, I find the whole process of getting Due advice and libraries difficult enough (forums, github, hobby sites, vendor sites, ebay ads). Keep the mindshare whole.

Daniel,
Bear in mind load_image is not actually loading anything from the SD chip.... Rather it is loading it from the 1963 LCD Flash.... It is stored in the LCD Flash by location...(hence the requirement for the function call to be fed 3 integer values, x, y, location id).
There is another sample sketch that tells you how to load/import a file from the SD chip into the LCD Flash....
None of it is as pretty as we'd like...but it's there.

Here's the benefit... If you can Import all of the images into the LCD Flash...then you no longer need to 'mount your file system...aka SD card' in your sketches. Therefore, that spares you loading some headers and doing extra defines that you won't use. Downside is..if the LCD goes bad...you will have to reimport all of the fotos...in other words, run the import sketch again.

Looks like cold tears even offers a windows based utility as one of the steps in the process...
I'll go through the process myself...as I have the same equipment. ;p
Peter
