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. |

Yea, me too.. No problem.
Send me free stuff and I'll write a driver for you too!

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 !). |

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:
For example, the code in the link below looks like it could be easily
translated to CCS, by editing this routine: Set_LCD_8B_REG()
http://read.pudn.com/downloads137/sourcecode/book/588322/HX8347.C__.htm
But there is no guarantee that it will work. And I don't want to do the
driver for you. |

Not even if he sends you like 5 LCDs??

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

Exactly as it reads. The board requires 5VDC power input that is regulated down to 3.3 for the display. _________________ Google and Forum Search are some of your best tools!!!! |

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???? _________________ ... |
