DWrite.gph : Display Text & Numbers via the Segment Display

Postby Scachi » Wed Dec 05, 2018 6:29 pm

**Updated: Added support for negative numbers and fix32 numbers

This header file adds two functions to display "Some Text" or (int32) Numbers via the Titan Two Segment Display.
Text speed and some other things are configurable.

It is available as a header file "DWrite.gph" only or as "DWrite_Example" that includes a gpc script for example usage.

Usage in your own script:
Download the Headerfile from the Online Resource.

Place this .gph file into the same folder where your script file is.
Add this line to the top of your script:
Code: Select all
#include "DWrite.gph"


! Do not call the functions on every interaction of main !
Only call it when you want to start the output of the text.

Basic Example:
Code: Select all
 
#include "DWrite.gph"
 
char *SomeText[] = {"First","Another word","number 12.5"};
int8 SomeNum=56;
 
init {
  // only call the DWrite function on event_press / release or a toggle state change.
  // calling it directly in the main loop will show the first character only all the time
 
  DWriteTxt("Hello");
  //DWriteTxt("This Is The Text To Display");
  //DWriteTxt(SomeText[0]);
  //DWriteTxt(SomeText[1]);
  //DWriteTxt(SomeText[2]);
  //DWriteNum(12457);
  //DWriteNum(SomeNum);
}
 
main {
  // dpad-up
  if (event_active(BUTTON_10)) DWriteTxt("abc");
  if (event_active(BUTTON_11)) DWriteNum(123);
  if (event_active(BUTTON_12)) DWriteTxt(SomeText[1]);
  if (event_active(BUTTON_13)) DWriteNum(SomeNum);
}

So I am kinda new to the T2 and trying to figure it out on my own but I am having trouble with this.

What part of the GPH file would I need to place inside my GPC script to allow the T2 to display a 2 digit # when a button is released when the T2 is only connected to the console?

Would this be close?

Code: Select all
// ---- Configuration ----
#define DWrite_MaxWrite  0     // when to stop textoutput: 0=complete text, 1=first whitespace, 2 or more for stop after n characters
#define DWrite_Wait      500   // 500ms for each character to display
#define DWrite_WaitNext  80    // 50ms before next character to display
#define DWrite_WaitNextD NULL  // the mask from display.gph to show between characters, default is none/NULL;
#define DWrite_Def       SEG_D // the mask from display.gph to use for unknown characters, SEG_D is the bottom segment
#define DWrite_Ws        NULL  // the mask from display.gph to use for whitespace, default is none/NULL;
//
#define DWRITE_NS // no special character like: dot slash underline (only a few supported atm)
#define DWRITE_LC // lowercase only (default) (converts upper to lower)
#define DWRITE_UC // uppercase only (converts lower to upper)
#define DWRITE_MC // uppercase and lowercase
#define DWRITE_DI // disable function DWriteInt(int32 Num) (number to char conversion output)
#define DWRITE_DF // disable function DWriteFix(fix32 Num) (fix32 numer to char conversion output)

Do not edit it or use parts of it only as this is not how you use header files.
..it is noted at the top of the file you have edited:
Code: Select all
//
//
// NOTHING TO EDIT HERE IN THIS FILE

Use the header file as described in the first post.

Change the basic example to use event_release instead of event_active.

I got it working. Thanks for your help and the time you put in to making the Header file.

Question: is there anyway to have the integers/text display twice instead of only one time then resetting to the slot #?

Let me know.

Also, I got this, but it wasn't a warning and it did not affect anything with the display output working properly. (below)

"Unreferenced" is something that is available but is not used at the moment. Getting rid of those unreferenced stuff can reduce bytecode / free up space.
The function "DWriteFix" is used to write fix32 decimals like 12.45 via the segment display.
My header file supports some switches to disables some functions or configure display options without having to edit the header file itself.
You can disable the function DWriteFix by adding this line above the #include line of the header file, so you have two lines now for the specific header file (still nothing to edit in the header file itself):
Code: Select all
 
#define DWRITE_DF // disables function DWriteFix(fix32)
#include "DWrite.gph"
 

When done right the "unreferenced" message should no longer show up as you have disabled the function.

Displaying the text twice isn't supported by the header file. This would make it hard to read the output correctly if the number is "2" and is displayed twice without the user knowing it. he will think it is "22" instead.

I don't know where/how you are using it to output some numbers. It might be easer to use L3/LS or some other button to output the number again instead of displaying it twice always

You can adjust the output speed and pause between the single numbers/text with more #define line before the #include of the header file too, again without editing the header file, you can configure its display options:

Example:
Code: Select all
 
#define DWrite_Wait      600   // time in ms for each character to display
#define DWrite_WaitNext  100  // pause time in ms before next character to display
#define DWrite_WaitNextD NULL  // the mask from display.gph to show between characters, default is none/NULL
#define DWRITE_DF               // disables function DWriteFix(fix32)
#include "DWrite.gph"

Thanks for the #define. Super helpful explanation, as well.

I did edit some of the display and pause values above the header.

It works great!

Thank you.

Small bugfix and added two more #define configuration options. redownload the example or header file for them to work.
The end combo didn't work at correctly before, returning to fast, showing the slot number quickly after displaying the numbers/text.
Code: Select all
 
#define DWrite_WaitEnd   300     // time at the end of the text to wait before showing the slot number again
#define DWrite_WaitEndD  NULL // the mask from display.gph to show at the end of text before showing the slot nr, default is none/NULL
