Introduction

Matrix-Compact Kit B.png
  • The Matrix Compact Kit B is a FriendlyARM developed compact board with various hardware resources, interfaces and ports. It contains user keys, LEDs, buzzer, ADC, compass, temperature sensor, IR receiver and TFT interface. It works with FriendlyARM's NanoPi 2 Fire and NanoPi M2 via its 40 pin male connector and is compatible with Raspberry Pi and Arduino boards. In addition you can connect various devices to its IO pin-header.

Features

Matrix - Compact Kit B contains the following components:

  • 0.9 TFT LCD
  • 3 x Switch
  • 4 x 5mm LED
  • Buzzer
  • ADC
  • Potentiometer
  • 40pin Female Connector
  • 4pin pin-header – I2C
  • 4pin pin-header – UART
  • 3pin double pin-header – 3.3V and GND
  • 18B20 Temperature Sensor
  • IR Receiver
  • 10 x 3pin pin-header – 3 x AIO & 7 x DIO (two can be configured to PWM and four can be configured to SPI)
  • Compass

Applications

Connect to NanoPi M1

Refer to the following connection diagram to connect the module to the NanoPi M1:
Matrix-Compact_Kit_B_nanopi_m1

Connect to NanoPi M2 / NanoPi 2 Fire

Refer to the following connection diagram to connect the module to the NanoPi M2/ NanoPi 2 Fire:
Matrix-Compact_Kit_B_nanopi_m2

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
The channel0 value is 2070
The angle is 336.3
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. Here is what you expect to observe:
st7735s-status

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
