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; }
