Testando o Display OLED

O display OLED é um componente que dá um toque especial a interfaces com usuário. A tecnologia OLED permite uma melhor legibilidade e não há a necessidade de uso de backlight, já que o próprio pixel emite luz.

Recentemente adquiri algumas peças para teste e vou explorar os seus recursos. O modelo que adquiri possui 128 x 64 px e comunicação I2C. O controlador desse display é o SSD1306 (vamos usar seu datasheet em breve).

Nesse artigo vamos ver o seu funcionamento usando bibliotecas existentes para a plataforma Arduino. Vamos lá?

Materiais

  • Arduino Nano(ou similar)
  • Display OLED 128 x 64
  • Protoboard
  • Jumpers

Circuito

Ligação:

  • SDA-A4
  • SCL-A5

Bibliotecas

Pesquisando, vi que as bibliotecas Arduino mais usadas para esse display são:

- Adafruit SSD1306 Library com a Adafruit GFX Graphics Library

- U8glib

Para nosso teste vou utilizar a biblioteca U8glib, que considerei mais completa. Mas fique a vontade para testar a biblioteca da Adafruit.

Código

Após instalar a biblioteca (que vem com muitos exemplos) na IDE, eu rodei o primeiro exemplo: Hello World

#include "U8glib.h"
U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NO_ACK);  // Display which does not send ACvoid draw(void) {
  // graphic commands to redraw the complete screen should be placed here  
  u8g.setFont(u8g_font_unifont);
  //u8g.setFont(u8g_font_osb21);
  u8g.drawStr( 0, 22, "Hello World!");
}void setup(void) {
  // flip screen, if required
  // u8g.setRot180();
  
  // set SPI backup if required
  //u8g.setHardwareBackup(u8g_backup_avr_spi);// assign default color value
  if ( u8g.getMode() == U8G_MODE_R3G3B2 ) {
    u8g.setColorIndex(255);     // white
  }
  else if ( u8g.getMode() == U8G_MODE_GRAY2BIT ) {
    u8g.setColorIndex(3);         // max intensity
  }
  else if ( u8g.getMode() == U8G_MODE_BW ) {
    u8g.setColorIndex(1);         // pixel on
  }
  else if ( u8g.getMode() == U8G_MODE_HICOLOR ) {
    u8g.setHiColorByRGB(255,255,255);
  }
  
  pinMode(8, OUTPUT);
}void loop(void) {
  // picture loop
  u8g.firstPage();  
  do {
    draw();
  } while( u8g.nextPage() );
  
  // rebuild the picture after some delay
  delay(50);
}
Olha como fica nítida a escrita

Esse código exibe a mensagem Hello World no display. Note que é necessário tirar o comentário a linha

U8GLIB_SSD1306_128X64 u8g(U8G_I2C_OPT_NO_ACK);

Assim é configurada a comunicação para o nosso display.

Dando sequencia no teste, agora vamos desenhar no display. Para carregar nossas próprias imagens vamos usar o programa LCD Assistant:

Eu carreguei a imagem de um carro:

Após o ajuste da imagem, clique em File->Save Output e salve o arquivo como .c

Copie o código gerado para o código Arduino. O meu ficou assim:

#include "U8glib.h"
