Matrix - 0.96' 128x64 OLED
From FriendlyELEC WiKi
1 Introduction
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

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。
