Here is a little experiment made with a fast SPI interface to a 480x272 TFT display.

Here is a very preliminary datasheet about what kind device this is:

This picture shows the test setup used to test with a 30 MHz SPI bit rate which is the maximum supported by the NXP LPC214x microcontroller used on the SPI master board (USB13700 board with it's GPIO API).

Currently this was just a quick experiment about fast SPI interface but if there is interest in this kind device and it might be useful let me know and more effort can be put into it.

Hi Henri ,,, Good day ...

I am interested to buy a driver / carrier board SPI043 only but unable to locate the price and ordering info on the site ...

Is this available for sale now ??

see my 2 developments across Graphics LCDs....

Hi Imran,

Like it was mentioned in the first post this was currently more an experiment and so there are no final units ready for sale at the moment.
But I also wrote that the development effort currently planned to this project is also dependent of how much interested users there might be for this so if you would like to buy a board with it's current firmware to play with it should be possible to build it for you. You can send me email and we can discuss about this.

Henri

Hello Henry

I am interested in purchasing SPI043 board. But i also want to know whether do u have any other board interfaced with a 3.5 inch LCD.
Thank you

Best Regards

We have discussed these things with Nithin in email but let's add an update here too.

The driver IC is custom logic in a FPGA so it is not some part number for which you would find a datasheet from somewhere else. The use of FPGA gives the board the flexibility of being able to customize the interface and features based on what is needed for the application. The Sharp LCD part number that has been used for these prototypes is LQ043T3DX02 but it is possible to make boards that fit other displays also.

There is no special 3.5" TFT board made at this time but for prototype needs a 3.5" TFT has been also attached using an adapter board. It can be seen in this picture:

A version of the SPI043 board customized for some specific 3.5" panel is something that could be discussed.

That looks great Henri,

SPI interfaced is what I am looking for, However I got some of these screens: http://www.rayslogic.com/Propeller/Prod ... isplay.htm They are 60 pin wide printed cable and the Sharp screen is only 40 pin wide.

Is there anything that can be done?
