8 Jan I have a board I bought from eBay that has a TFT with the HXA driver. I am a but lost as to what is needed for interfacing to the Microchip. 1 Jun DATA SHEET. (DOC No. HXADS). HXA RGB x dot, K color, with internal GRAM,. TFT Mobile Single Chip Driver. 25 Mar Now the ILIC display controller chip has been discontinued and now the available and alternative model is ILID. Our ITDB LCD.

Turns out the board also has a regulator that needs to be hx8437 minimum of 4V. To find out more, including how to control cookies, see here: Top Blog at WordPress.
What devices do you actually have? Black Rynius’ Blog Microcontrollers and other nerdly goodness…. Look like what they have is an 8 bit address bus and an 8 bit data bus.
Thanks to your explanation, this might not be as bad as I first thought. Also, I need to find someplace to post code….
I will keep searching. For Color data, there may be 8, 9, hd8347 or 18 parallel data lines.
But Hx83347 was using generic sample xh8347 for the device and all I was finding was the same code commented in Chinese that comes with the board. However, that fun will probably have to come out of a different microcontroller. Do I wire the lower 8 bits of the controller or the upper 8 bits? But when I look it up, the product page says optimized for 16 and 32 bit mcu?
Email required Address never made public.
What do I do with the remaining pins? The PIC i use is a 18F I think it would be useful to know why the programmer of that code is initializing the device the way he did. Getting started with the HXA?
Getting started with the HX8347-A?
I see the various registers that you mentioned but I am not sure I understand what they all do. You will not get away from studying the datasheet. Comments 5 Trackbacks 0 Leave a comment Trackback. Where I got the address idea from is how they commented the code. The display controller do not use a address bus, there is at most 1 control line that may be regarded as a address signal: When RS is 1, high logic level: I ported mines from my 1.
I’m surprised you didn’t start with Google. They give a sample schematic.
Mysil Hi, You have let yourself into a complicated field. I’d start with a C18 install, and get it running before porting to XC8 for further development. Thanks for finding it.

Code was also provided, that ported to a pic18F rather easily, that is once power requirements were satisfied. All I have on hand are 8 bit pics. You will need a Datasheet for the HX display controller.
My problem is it is so huge I am not sure what to look at for the various commands. This code looks excellent. Thanks yes I did search. By continuing to use this website, you agree to their use. Here is a piece of code handling the display controller: Essentials Only Full Version.
There’s C18 code for it here: Anyone can make any sense of what they are doing?
