1 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.

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;
}
