91  Products / Arduino Due / Re: Due I2C Voltage on: December 21, 2012, 06:40:47 am
Hello all,

as mentioned here http://arduino.cc/en/Main/ArduinoBoardDue
Arduino Due's I/O Voltage was changed from 5V to 3.3V.

Does this also mean that we have to change the voltage of the I2C Devices like DS1307, DS1820?

Thanks
Ben
Think so I'm sure (I don't have the I2C Spec to read it) but if the Chip (DS1307 or DS1820) works with 5V the I2C would talk with it to, so if the IC can understand I2C with 3.3V he can listen but the answer would at 5V level so it will damage the Due

I wired it up according to UTFT's documentation, adapting it to the specific TFT. It was not difficult. I should point out that it is an ITDB32WD compatible display that I got off of ebay, and not an ITead original.

The display works natively with 3.3V logic (I had to use resistors to use it with the older Arduinos) so it is actually easier to interface to the Due than to older Arduinos.

Did someone has an benchmark from the lib between oldone on mega how fast is it?

I try to convert the UFT Clock from Henning Karlsen to work with the Due http://henningkarlsen.com/electronics/p_utft_analog_clock.php. But my Calender is blinking the clock is working proper.

One more thing.. Henning's utouch library (support for touch screen) works out of the box on due..

So now we have initial support for touchscreens with sd slots for due.
Henning's utouch library works without any changes.

on atmel studio 6 I can printf just fine using the sample code (Atmel Frame work examples) ..
 but input looks to be a differnt baud rate   
not a killer problem but pretty silly ...



/ works fine with sketch  so not the terminals (tried both putty & serial monitor)
All Framework Sample have the baud rate 115200

Has anyone successfully used the calibration sketch on a 3.2WD screen  - I am having no luck in getting it to work correctly. When I run subsequently run the Quick Draw example I get a mirror image on the long axis.

Orientation problem, easy to fix by changing the orientation value to fit your needs smiley

I gather you mean to change the orientation of the screen and/or touch panel to either Portrait or Landscape in the initialisation??

I have tried all different combinations with different/ but still incorrect, results.
You need to do the calibration Sketch first and edit then the UTouchCD.h

or alternativ test mine I have the same panel.

Maybe USART0 can become an weak handler so I can override it?

Cool work you did there. Nice set of Data you collected.

I'm sorry, there seems to be a mixup.. I was replying to a post that now appears to be gone (it was regarding a shield that simplified wiring a TFT to a MEGA). smiley-sad
Yes that was me, my post and I killed the post in hurry klicked the wrong button.

I found this Shield http://imall.iteadstudio.com/development-platform/arduino/shields/im120417024.html that works with Boards with 3.3V or 5V so it would make it easy to use an TFT with the UTFT Lib and dimdim's modifications. So you have the tft and the touch function together.
99  Products / Arduino Due / Re: Due compatible Time library? on: December 12, 2012, 12:31:23 pm
Sorry for the delay, but yesterday I was busy with work till late.
Just compiled with your library, after translating function calls, and it seems to work correctly smiley-grin
Thank you very much.
By the way, the interface to the rtc_clock is clean and simple, very nice work.
Even if at the moment I dont use it, also the interface for the alarm:
  rtc_clock.set_alarmtime(10, 30, 0); 
  rtc_clock.attachalarm(announcement);
  void announcement(){
    ...
  }
is very clean and I love it.
Thank you again
Thanks for the response.

No hurry, lovely that you like it. btw you can set Hours, Minuets and Seconds seperate for the time too, and the function to call the Alarminterrupt takes me the most time.

Hi folks,

I get in some serious trouble porting the Lin example from the Atmel Framework. Some parts of the Lin example works on the USART0_Handler and the problem is the Handler is allready defined on the variant.cpp.

I try to integrate it without break up parts in the existing files. I can reuse easily the pdc, lin and usart files frome the example and itegrate them in the Arduino IDE, but the Interrupt makes me cry.

Can some one lend me an helping hand for this.

Best regards

Markus

So folks,

I have ported all nessecary files from the LIN_MNGT_EXAMPLE for the Arduino, I get it so far that it compile without any errors. I will test it on an Lin Master when I get one. One problem left I can't handle the UART0_HANDLER by define them out in the variant.cpp and de/activate him in the sketch. the variant.cpp is handled first by the compiling. Comment it out is not the fine art of doing it. Are there other ways of getting this in the right way.

Next step cleaning the files up.

B.R.

Markus

Btw. I missed functions to enable and dissable the Interrupts in the tc.c

Markus is/was writing one and has posted recently.

Yes I did, if you have any questions, suggestions or if you need an function let me know.

I have tried amolinero's version of the UTFT library with my ITDB32WD display with great results, as you can see in the attachment.



Tomorrow I will also try it with my own code and see if everything also runs OK.


How did you wire it up?

Did it work proper with 3.3V Logic?

104  Products / Arduino Due / Arduino Due RTC Library on: December 07, 2012, 05:43:57 am
Hi folks,

there are my first "final" release of the RTC Library for the Arduino Due.

2 examples included.

I would call it final for the moment.

And on github: https://github.com/MarkusLange/Arduino-Due-RTC-Library

Have fun

105  Products / Arduino Due / Re: RTC_library for Due Problems with Alarm and Interrupts on: December 07, 2012, 02:41:00 am
Hmmm,

seems like a fixed for this is deactivating the seconds interrupt.

Code:
RTC_EnableIt(RTC, RTC_IER_SECEN);

In this situation its enough if I didn't activate it.
