When shield Deuligne assembly is finished and library installed, it's time to try some funny sketches (there is a bunch of examples in the library, do not hesitate to try them all !)
Custom characters creation :
Hardware used :
deuligne... obviously
arduino... (see previous comment)
Liquid crystal displays used on the "Deuligne" shield are able to keep 8 custom characters in their internal memory.
As an example today, I'll integrate the Snootlab logo (in fact an hardly pixelated version) inside text.
First of all, we need to create the custom characters used for the logo.
To do this, there is a wonderful tool created for the Liquid Crystal Display library.

Tick or untick the boxes to design the logo et the character code (red outerlined) is real time updated.
- We've to create the logo second part...
- Code: Tout sélectionner
#include "Wire.h" // I2C library insertion (needed)
#include <Deuligne.h> // Deuligne library insertion (needed)
Deuligne lcd; // lcd object declaration
// Custom characters code
byte left[8] = {
B00010,
B10110,
B11111,
B11111,
B10001,
B10101,
B10001,
B01110
};
byte right[8] = {
B00100,
B01101,
B11111,
B11111,
B10001,
B10101,
B10001,
B01110
};
void setup() {
Wire.begin(); // I2C init (needed)
lcd.init(); // LCD init (needed)
lcd.createChar(0, left); // left character creation and assign it to 0
lcd.createChar(1, right); // right character creation and assign it to 1
lcd.backLight(true); // Backlight is on
lcd.setCursor(0, 0); // Set cursor to 0,0 (1ere ligne, 1er caractere)
lcd.print("Sn"); // Print the text beginning
lcd.setCursor(2,0); // Set cursor just after the text
lcd.write(0); // and write the character 0 (left side of the logo)
lcd.setCursor(3,0); // Set cursor just after
lcd.write(1); // write the character 1 (right side of the logo)
lcd.setCursor(4, 0); // Set cursor just after again
lcd.print("tlab"); // to finish to write the text
lcd.setCursor(4, 1); // ok, it's under control now
lcd.print("Le Deuligne"); // I can stop to comment...
}
void loop() {}
Copy and paste the characters code and insert it in dedicated sketch.
Now, you just have to compile, upload and.... go !!!
More examples to come, stay tuned !!!
