No problem, please send me 5 pieces of the display and allow 3-4 weeks for the basic driver for the display to be made,I'll require 2 additional pieces and another 2 weeks if you want a driver for the touch screen.

Ah Ben , your're stealing my toys and money !!! LOL

Really, after 30+ years of giving it away, I've finally decided MY time and knowledge has to be worth something. If I can do in day what takes another a week or month, that has to have a value.

I actually enjoy cutting code for devices(aka drivers), in the 'old ' days it was all assembler(PDP11, 6800,Z80, 1802), nowadays with C it's fairly fast and easy(Can't go grab a coffee before the compile is done !).

You and my Atari 800 would probably get alone real nice..

There is code for the display at various sites on the internet, but it's not
written for CCS. Search for the following with Google:

Hi to all.. after reading datasheet so many time and other stuff i have final able to run the display. It's really a good learning curve for me.
Thank you guys to make me work myself.
I am still running my TFT and controller with 3.3v
Its website said:

* Onboard 3.3V regulator require a single 5V supply
* 3.3V I/O voltage level tolerance

First statement is clear i do understand.
But the second one is a sort of confusing for me.
Its ok to give 5v on its IO pins???

NO !!!!

* 3.3V I/O voltage level tolerance

Means the Input/ Output pins require 3.3V NOT 5 volts.

So you either have to use a 3.3V PIC or use resistors as voltage dividers to reduce the 5 volts from the PIC down to 3.3 volts for the LCD.

Something like a 1k from the PIC pin to 1.8K tied to ground. The midpoint should goto the LCD and be about 3.2 volts. Breadboard to confirm BEFORE wiring to the LCD.

then what does this statement means..
* Onboard 3.3V regulator require a single 5V supply

it confused me alot
help me

Exactly as it reads. The board requires 5VDC power input that is regulated down to 3.3 for the display.

then the next statement is totally opposite..
* 3.3V I/O voltage level tolerance

it says pins required not more then 3.3V..

is it what it is saying????
