1 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.

2 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

4 硬件连接

4.1 连接NanoPi M1

参考下图连接模块:
Matrix-Compact_Kit_B_nanopi_m1

4.2 连接NanoPi M2 / NanoPi 2 Fire

NanoPi M2和NanoPi 2 Fire的40 Pin引脚定义是一模一样的,所以它们操作Matrix配件的步骤是一样的,这里仅以NanoPi M2为例。
参考下图连接模块:
Matrix-Compact_Kit_B_nanopi_m2

5 编译运行测试程序

启动开发板并运行Debian系统,进入系统后克隆Matrix代码仓库:

$ apt-get update && apt-get install git
$ git clone https://github.com/friendlyarm/matrix.git

克隆完成后会得到一个名为matrix的目录。

编译并安装Matrix:

$ cd matrix
$ make && make install

运行测试程序:

$ matrix-compact_kit

注意:此模块并不支持热插拔,启动系统前需要确保硬件连接正确。
运行效果如下:

LED blinking 1
LED blinking 2
Button:  1 1 1
The channel0 value is 2070
The angle is 336.3
Pwm start
Pwm stop

运行Qt程序,测试TFT屏:

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

程序会显示出系统的基本信息,效果如下:
st7735s-status

6 代码说明

所有的开发板都共用一套Matrix代码,本模块的测试示例代码为matrix-compact_kit,内容如下:

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;
}
