Nicu FLORICA (niq_ro): Prezentare "frumoasa" sketch/program in articol

Am gasit pe un site, prezentare frumoasa a unui sketch pentru Arduino, e vorba de program.., eu il selectam, schimbam tipul de text si culoare si.. cam atat, ceva de genul:

#include <Wire.h>
#include <LiquidCrystal_I2C.h>
LiquidCrystal_I2C lcd(0x20,16,2); // 0x20 is adresss for LCC 16x2
void setup(){
lcd.init();
lcd.backlight(); //backlight is now ON
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
// Print a logo message to the LCD.
lcd.print("www.tehnic.go.ro");
lcd.setCursor(0, 1);
lcd.print("creat de niq_ro");
delay (2500);
lcd.clear();

// Print a permanent message to the LCD.
lcd.print(" teste interfata");
lcd.setCursor(0, 1);
lcd.print("i2c pt. LCD 16x2");
delay (2500);
}
void loop(){
delay(1000);
}

dar am gasit la Source Code Formatter for Blogger, Blogspot , Blog & Blogging, Format Formatting Tool un utilitar de formatare, astfel ca acel cod va arata asa:

 #include <Wire.h>  
 #include <LiquidCrystal_I2C.h>  
 LiquidCrystal_I2C lcd(0x20,16,2); // 0x20 is adresss for LCC 16x2  
 void setup(){  
   lcd.init();   
  lcd.backlight(); //backlight is now ON  
  // set up the LCD's number of columns and rows:   
  lcd.begin(16, 2);  
  // Print a logo message to the LCD.  
  lcd.print("www.tehnic.go.ro");   
  lcd.setCursor(0, 1);  
  lcd.print("creat de niq_ro");  
  delay (2500);  
  lcd.clear();  
  // Print a permanent message to the LCD.  
  lcd.print(" teste interfata");  
  lcd.setCursor(0, 1);  
  lcd.print("i2c pt. LCD 16x2");  
  delay (2500);  
 }  
 void loop(){  
   delay(1000);  
 }

Poate nu am fost explicit, deoarece acel sketch nu era foarte lung, dar unul de peste 400 de linii, de genul ultimului din articolul Afisaje LED cu 7 segmente si.. Arduino (II), care arata asa:

This code is public domain but you buy me a beer if you use this and we meet

someday (Beerware license).

4 digit 7 segment display:

http://www.sparkfun.com/products/9483

Datasheet:

http://www.sparkfun.com/datasheets/Components/LED/7-Segment/YSD-439AR6B-35.pdf

This is an example of how to drive a 7 segment LED display from an ATmega

without the use of current limiting resistors. This technique is very common

but requires some knowledge of electronics - you do run the risk of dumping

too much current through the segments and burning out parts of the display.

If you use the stock code you should be ok, but be careful editing the

brightness values.

This code should work with all colors (red, blue, yellow, green) but the

brightness will vary from one color to the next because the forward voltage

drop of each color is different. This code was written and calibrated for the

red color.

This code will work with most Arduinos but you may want to re-route some of

the pins.

In mare, este folosita comanda pre din limbajul HTML, dupa cum se vede si in articolul de la http://www.w3schools.com/tags/tag_pre.asp.
Pentru usurinta editarii se scrie articolul in modul "scrieti",

apoi se copiaza sketch-ul pe care doriti sa-l postati in fereastra Paste Here Your Source Code de la http://codeformatter.blogspot.ro/

puteti alege niste nici parametrii ai ferestrei si textului

si veti optine codul html care trebuie sa-l inserati in articolul din blog (mai jos si cum va arata):

Trebuie sa selectati textul din fereastra Copy Formatted Source Code, apoi sa treceti in modul de editare HTML

duceti cursorul la finalul textului de acolo si apasati simultan tastele CTRL si V (adica PASTE/LIPIRE) si apoi mai scrieti un </br>.

Treceti iar in modul normal "scrieti" si continuati editarea...

How LiquidCrystal_I2C library have you used?
I receive these error in check sketch by IDE :

LiquidCrystal_I2C lcd(0x20,16,2); // 0x20 is adresss for LCC 16x2
invalid conversion from 'int' to 't_backlighPol'

sketch_jul25b:3: error: invalid conversion from 'int' to 't_backlighPol'
sketch_jul25b:3: error: initializing argument 3 of 'LiquidCrystal_I2C::LiquidCrystal_I2C(uint8_t, uint8_t, t_backlighPol)'
arduino-1.0.3\libraries\LiquidCrystal/LiquidCrystal_I2C.h: In function 'void setup()':
arduino-1.0.3\libraries\LiquidCrystal/LiquidCrystal_I2C.h:154: error: 'int LiquidCrystal_I2C::init()' is private
sketch_jul25b:5: error: within this context

thanks!

PS have you 3 pull-up resistors on SDA SCL and PWM on DS1307?

Salut,

Pentru afișarea codului sursa în postare recomand SyntaxHighlighter -> http://alexgorbatchev.com/SyntaxHighlighter/. Pe site găsești cum se instalează și cum se folosește.
