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。

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.

==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[])

    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");
