Hello,

I have a Arduino color graphic TFT display.
See: http://arduino.cc/en/Main/GTFT
(It is a nice display and has a micro-SD slot on the back.)

I want to use it with a CGMMSTICK1 but I don't know how to connect it.
(I HAVE connected with an Arduino UNO and have had it work with the demo 'sketches'.)

Would it require a special MMBasic library to make it function? (I am thinking it would require a lot of work to direct MMBasic graphic commands to the display, but I hope I am wrong.)

The TFT display could make for a nice color display, the micro-SD might be nice too, but I am really interested in just making the display work.

Thanks in advance for any help at all.

@OldMMUser

To get the display working with a CGMMSTICK1 will require specific coding within MMBasic (i.e. custom subroutines). However I can assure you that the end result would be rather slow.

Another thing to consider is the TFT Maximite. This gives options for either a 4.3" or 5" TFT with a crisp display running at 480x272 pixels. It also incorporates a resistive touch screen. Bearing in mind the low cost of chinese imported TFTs you could get a display with touchscreen for around US$20-25.

This solution makes it easy to code for graphics and touch buttons as well as having access to all MMBasic features on one display.

One final thing to keep an eye on is OldBitCollector's MicroMite Companion which integrates a Propellor micro controller with a MicroMite. This works on a VGA monitor which could be replaced by a TFT (with vga input module) if small display size is important.

I am not ruling out the display you refer to - just think the effort required for the end result achieved may result in disappointment.

Lets see what other people suggest . . . .

That would be much easier in interfacing it using a Firewing board and language (VB,NET) and results will be on par with Arduino if you use an 8bit microcontroller, or much better if a 16bit/32bit one is used.
