The DVI Graphics Shield gives you true color (24-bit) output to DVI monitor at up to 864x480 resolution (VGA or WVGA) and can also output to analog VGA or 4.3" or 5" touchscreens using available plugin adapters.

Can be connected as a shield for Propeller Prop Platform or used in any generic microcontroller setup with 12 I/O pins (generic 8080 interface) at 3.3 V.

   Shown mounted on Propeller Platform USB.

Uses the Solomon SSD1963 graphics controller (large chip on left) with 1215 kB of RAM to generate digital VGA signal and Ti TFP410 DVI transmitter (smaller chip on right) to convert to DVI.

A very low cost DVI to HDMI cable allows you to display on newer TVs.

Only 12 I/O pins are required for 8080 8-bit bus interface to SSD1963 (D0..D7, CS, DC, WR and RD).

Requires 3.3 VDC and 5 VDC power (although 5 VDC may not be required in all cases).

Optional I2C interface (SDA and SCL) allows optional access to DVI transmitter or expansion.

The central 40-pin connector allows for VGA and 4.3" TFT panel plug-in boards:

VGA Plug-In:  Provides analog VGA signal and DB15 connector (Now Available!)

Just modify this line in the driver file when using VGA Plugin:

bUsingVgaPlugin=true 'false 

Touchscreen Plug-In:  Provides 4.3" LCD panel interface for Samsung and Newhaven 480x272 pixel 4.3" touchscreens and also provides touchpanel input over I2C (Now Available!).

Note:  Both connectors are "bottom contacts" type, so insert contact side down.

There's a special version of the driver that runs both Samsung and Newhaven 4.3" touchscreens.

Update:  Can also drive the Newhaven 5" LCDs with a resolution of 800x480!

Capacitive Touch:

Newhaven 4.3" and 5" capacitive touch LCDs can now be used by adding in a small adapter and running four jumper wires as shown here:

Example Propeller Code:

Here is the latest demo for 640x480 VGA or DVI output mode

To see the bitmaps, you'll need to copy these bitmap files onto connected SD card

Note:  Because of a bug in the Prop Tool, do not run when it has the included file "VGA_HiRes_wHeader.dat" opened.

Here is a new demo that shows variable pitch font support

It also compares this 1-bit font to a contemplated 24-bit font if you put this file with the 24-bit font on the SD card.

Download here the code for the demo shown in the video (with older version of the driver)

Here is an example that shows PowerPoint slides that were saved as 640x480 bitmaps (mounted on PropBOE).

Here is a demo example for 4.3" touchscreens.

Here are example bitmap files

Here is a demo example for Newhaven 5.0" resistive touchscreens.

Here is a simple example for the Newhaven 5.0" capacitive touch touchscreen.

Here is an example of how you can show custom fonts captured using RaysFontEditor
