1 Introduction

Matrix-Compact Kit.png
  • The Matrix-Compact Kit is a compact board with various hardware resources, interfaces and ports. It includes user keys, LED, buzzer, ADC, compass, temperature sensor, IR receiver, TFT port and etc. This board can be connected to the NanoPi, NanoPi 2 and Raspberry Pi via its 40 pin header. In addition you can connect other external modules to its GPIOs.

3 Applications

3.1 Connect to NanoPi 2

Refer to the following connection diagram to connect the module to the NanoPi 2:
Matrix-Compact_Kit_nanopi2

4 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-compact_kit

Note: this module is not plug and play therefore before running the module please make sure it is connected to an ARM board.
Here is what you should observe:

LED blinking 1
LED blinking 2
Button:  1 1 1
ADC channel0: 550
Compass angle: 328.5
Pwm start
Pwm stop

Run Qt program to test the TFT LCD: 

cd matrix/demo/nanopi-status
./build.sh
./run.sh /dev/fb-st7735s

The program will present the system's basic information:
st7735s-status

5 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-compact_kit". Here is its source code: 

int main(int argc, char ** argv)
{
    int board;
 
    if ((board = boardInit()) < 0) {
        printf("Fail to init board\n");
        return -1;
    }
    testLED(board);
    readButton();
    readADC();
    readCompass();
    testPWM(board);
    // readTemp();
    // testIR();
 
    return 0;
}

For more details about this APIs called in this code sample refer to Matrix API reference manual

6 Code Samples in Python

The Python version is 2.7.9 in the following samples
Install the Python libraries and modules: 

$ apt-get install Python-dev libi2c-dev

The python code is in our github: 

$ git clone https://github.com/friendlyarm/matrix-python.git

After it is done a matrix-python directory will be generated.

Access LED: 

$ cd matrix-python/Matrix.GPIO
$ python setup.py install
$ python test/matrix_output.py 33

The red LED will be flashing.

Read KEY1： 

$ cd matrix-python/Matrix.GPIO
$ python setup.py install
$ python test/matrix_input.py 36

When you press KEY1 "value" will be set to 0. When you release KEY1 "value" will be set to 1.

Test AD: 

$ cd matrix-python/modules
$ modprobe pcf8591
$ cd ../Matrix.pcf8591
$ python setup.py install
$ python test/matrix_adc.py

When you change the resistor AD value will be changed accordingly.

Test Compass: 

$ cd matrix-python/Matrix.I2C
$ python setup.py install
$ python test/matrix_compass.py

When you rotate the compass you will get changing direction values.
