Hi,
I have received 2.2" TFT GLCD with SPI Interface (http://www.ebay.com/itm/200939222521?ss ... 1439.l2649) but can not find the way to connect it. Can you help?

With best regards,
Djordje

Hi
the display has to be connected to 3.3v both the vcc and the spi require this voltage, you can either buy a ready made level converter or buy a cd 4050 to get the 3.3v inputs, also use the 3,3v pin on the duemelove to pover the tft and to power the level converter

Hi Dazz,
thank you so much for replying. My problem is also connecting other pins. Should I use gLCD EBM001 (or what) and how should I connect it? There is no "A0" or "Data" pin on the display ( which are present in EBM001 connections properties) but instead I have D/C, SDO, SDI pins. Should SDI be connected to "Data" in EBM001? What should be connected to D/C? Do I have to use specific pins on Arduino Duemilanove board?
Please help.

Hi
I think the closest will be the eb057 although its a different size, dont try it using 5 volts, but best bet would be to find the datasheet with the commands on and see if matrix can make a component for it

I have tried to contact Matrix concerning creation of new component, but could not send them datasheet for the display as an attachment (no option for attachment). Here it is. It also have codes and examples and I believe it would beneficial to many users to have such a component in the library as I have seen many displays with this chip / pinning. In case anyone can help, please...

Hi
post your request in this forum http://www.matrixtsl.com/mmforums/viewforum.php?f=56 as it may be seen, also please realise that matrix may be aware of this thread ,but could possibly be busy so it may take a while, also the Vc are not employed by matrix and try to help others in our spare time, i will have a look at the docs you posted and maybe able to offer a few suggestions, but as im living through hell at the moment, i will be unable to try to make a component and it may take a while to read the doc,

Hi Dazz,
thank you very much for trying to help. I am aware that you are doing this in your free time and that makes your help much, much more valuable. Hope you'll sort things out in your life soon. Just relax and do one thing at a time.

All the best to you !

Hello,

I've had a look at the code and it looks easy enough. I'll try and have a go at making a component this week but there is a lot for us to get through at the moment so please bear with us.

G R E A T !!!

Hello,

Right I've not been able to test this works on hardware but it should be fairly close.
Copy the attached file to your "C:\Program Files (x86)\Flowcode 6\components" directory and restart Flowcode.

Then the component should be available under the component search option. If you type glcd into the filter then the component search window will show all the current glcd components.

Let me know how you get on.

i have tested this on hardware, and unfortunately it doesnt seem to work, only a half of the screen seems to start up (horizontally)
and also if you write text, it goes off the screen. when it starts up, half of the screen is white and the other side, all of the pixels are different random colours, i hope this helps to maybe find a way to modify a driver for it to work properly.

i have however tried the built in driver in flowcode 6, and it seems to drive the glcd very well, apart from the problem where the refresh rate is painfully slow.

thanks,
matt

Hi Hypamat,
which driver in Flowcode 6 did you use? I didn't make it work with any (Also didn't know which one to choose). Can you help?

i went to outputs - glcd ebm001 and connected it that way, it does respond slowly, however.

thanks,
matt
