这是一款精致小巧的单色OLED显示屏，只有0.96英寸，分辨率是128x64，可以用来显示文字或图案。因为OLED是自发光的，所以无需背光，对比度高，功耗低。此配件5V供电，PCB上的电源转换芯片输出3.3V给OLED，通讯接口是SPI或I2C，信号电平为3.3V。默认通讯方式是SPI，如果需要改为I2C，您可以通过修改PCB上的配置电阻实现。

==Download Matrix Source Code==
 +
All the matrix modules' code samples are open source. They are maintained on GitHub --https://github.com/friendlyarm/matrix.git <br>
 +
Each branch in this hub contains the matrix modules' code samples for a board that the matrix modules can work with.<br>
 +
* The nanopi branch contains the matrix modules' code samples for the NanoPi
 +
* The nanopi 2 branch contains the matrix modules' code samples for the NanoPi 2
 +
* The tiny4412 branch contains the matrix modules' code samples for the Tiny4412
 +
* The raspberrypi branch contains the matrix modules' code samples for the RaspberryPi
 +
 
 +
Please follow the steps below to get the source code:<br>
 +
Install the git utility on a PC running Ubuntu14.04
 +
<syntaxhighlight lang="bash">
 +
$ sudo apt-get install git
 +
</syntaxhighlight>
 +
 
 +
Clone the matrix code from GitHub
 +
<syntaxhighlight lang="bash">
 +
$ git clone https://github.com/friendlyarm/matrix.git
 +
</syntaxhighlight>
 +
If this is successful a "matrix" directory will be generated, which will contain all the matrix modules' code samples.

5 Compile & Run Test Program

Boot your ARM board with Debian and copy the matrix code 

$ apt-get update && apt-get install git
$ git clone https://github.com/friendlyarm/matrix.git

If your cloning is done successfully a "matrix" directory will be generated.

Compile and install Matrix: 

$ cd matrix
$ make && make install

Run test program: 

$ matrix-oled

Here is what you should expect:
matrix-oled_result
The OLED displays the following two lines:
"ABCDEFGHIJKLMN"
"123456789"

6 Code Sample

This Matrix code sample can work with all the ARM boards mentioned in this module's wiki. The name of this code sample is "matrix-0.96_128x64_oled". Here is its source code: 

int main(int argc, char *argv[]) 
{
    int devFD;
 
    if (boardInit() < 0) {
        printf("Fail to init board\n");
        return -1;
    }
 
    if ((devFD = OLEDInit(GPIO_PIN(7), GPIO_PIN(11))) == -1) {
        printf("Fail to init OLED\n");
        return -1;
    }
    OLEDCleanScreen(devFD);
    // Char bitmap: 8x16
    OLEDDisp8x16Str(devFD, 0, 0, "ABCDEFGHIJKLMN");
    OLEDDisp8x16Str(devFD, 0, 16, "123456789");
    OLEDDeInit(devFD);
 
    return 0;
}
