1 Introduction

0.96inch 128x64 OLED

This is a tiny single color OLED. It is 0.96" and 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 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 its communication interface to I2C you can change module's resistors.

2 Features

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

3 使用方法

3.1 连接

• 连接到Tiny4412 SDK (1506)

GND针脚: 接地

VCC: 接5V

CLK针脚： 连接SPI CLK

MOSI针脚：连接SPI MOSI

RES针脚： 连接GPIO PIN1

DC针脚： 连接GPIO PIN2

CS针脚： 连接SPI CS

3.2 Linux下的C示例

#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;
}

3.3 编译并运行示例

git clone http://github.com/friendlyarm/fa-hardware.git
cd fa-hardware
cd demo
cd matrix-0.96inch_128x64_oled
make

将编译生成的OLED通过ftp上传到开发板上运行即可测试。
