Introduction

0.96inch 128x64 OLED

This is a tiny single color OLED. Its dimension is 0.96". Its resolution is 128 x 64. It can display text and graphics.It is high contrast and low power consumption. This module is powered by 5V which is then converted to 3.3V to OLED. It communicates via SPI or I2C. Its signal level is 3.3V. By default it communicates via SPI. If you want to set it to I2C you can change the module's resistor configuration.

Features

  • Tiny
  • High contrast, low power consumption
  • SPI/I2C
  • 2.54mm spacing pin header

Code Sample in C under Linux

#include <stdio.h>
#include "libfahw.h"

int display(int x, int y, char* str)
{
    int devFD;
    if ((devFD = OLEDInit(TINY4412_GPIO_PIN1, TINY4412_GPIO_PIN2)) == -1) {
        printf("Fail to init OLED\n");
        return -1;
    }
    // Char bitmap: 8x16
    OLEDDisp8x16Str(devFD, x, y, str);
    OLEDDeInit(devFD);
    return 0;
}

int main(int argc, char *argv[]) {
    display(0, 0, "1234567890");
    display(0, 16, "ABCDEFGHIJK");
    return 0;
}
