For more details about this APIs called in this code sample refer to [[Matrix API reference manual]] <br>
 +
 
 +
<!---
 +
==Download Matrix Source Code==
 +
All the matrix modules' code samples are open source. They are maintained on GitHub: https://github.com/friendlyarm/matrix.git <br>
 +
Each branch in this hub contains the matrix modules' code samples for a board that the matrix modules can work with.<br>
 +
* The matrix-nanopi branch contains the matrix modules' code samples for the NanoPi;
 +
* The matrix-nanopi2 branch contains the matrix modules' code samples for the NanoPi 2;
 +
* The matrix-tiny4412 branch contains the matrix modules' code samples for the Tiny4412;
 +
* The matrix-raspberrypi branch contains the matrix modules' code samples for the RaspberryPi;
 +
 
 +
Follow the steps below to get the source code<br>
 +
Install the git utility on a PC running Ubuntu14.04
 +
<syntaxhighlight lang="bash">
 +
$ sudo apt-get install git
 +
</syntaxhighlight>
 +
 
 +
Clone the matrix code from GitHub
 +
<syntaxhighlight lang="bash">
 +
$ git clone https://github.com/friendlyarm/matrix.git
 +
</syntaxhighlight>
 +
If this is successful a "matrix" directory will be generated, which will contain all the matrix modules' code samples.
 +
 
 +
==Connect to NanoPi 2 Fire==
 +
===Hardware Connection===
 +
Refer to the following connection diagram to connect the Matrix-Compact_Kit_B to the NanoPi 2 Fire<br>
 +
[[File:Matrix-Compact_Kit_B_nanopi2.jpg|frameless|600px|Matrix-Compact_Kit_B_nanopi2]]
 +
 
 +
===Compile Test Program===
 +
Login to the matrix hub and enter the nanopi2 branch
 +
<syntaxhighlight lang="bash">
 +
$ cd matrix
 +
$ git checkout nanopi2
 +
</syntaxhighlight>
 +
 
 +
Compile the Matrix code
 +
<syntaxhighlight lang="bash">
 +
$ make CROSS_COMPILE=arm-linux- clean
 +
$ make CROSS_COMPILE=arm-linux-
 +
$ make CROSS_COMPILE=arm-linux- install
 +
</syntaxhighlight>
 +
Note: make sure to install the cross compiler "arm-linux-gcc-4.9.3" on your PC, which is used to compile files for the NanoPi 2.<br>
 +
Generated library files are under the "install/lib" directory. The test program is under the "install/usr/bin" directory.<br>
 +
The modules are under the "modules" directory. The driver's source code is in github: https://github.com/friendlyarm/linux-3.4.y.git <br>
 +
 
 +
===Copy Test Program===
 +
Insert a TF card which is flashed with Debian into a Linux host and mount its boot and rootfs sections.<br>
 +
We assume the rootfs is mounted to /media/rootfs then run the following commands to copy the module, library and test program to the card.<br>
 +
<syntaxhighlight lang="bash">
 +
$ cp modules /media/rootfs/ -r
 +
$ cp install/lib/* /media/rootfs/lib/ -d
 +
$ cp install/usr/bin/* /media/rootfs/usr/bin/
 +
</syntaxhighlight>
 +
 
 +
===Test LCD===
 +
Insert this TF card to your NanoPi 2 Fire, power on and run the following commands.<br>
 +
<syntaxhighlight lang="bash">
 +
$ cd /modules
 +
$ insmod fbtft_device.ko name=matrix-st7735s gpios=dc:58,reset:63,cs:59
 +
$ sudo FRAMEBUFFER=/dev/fb-st7735s startx &
 +
</syntaxhighlight>
 +
"fbtft_device" is the LCD's driver.After it is loaded the LCD will be initialized.<br>
 +
"startx" sets the LCD to the output device. Here is what you should expect:<br>
 +
[[File:03.jpg|frameless|600px|03]]
 +
 
 +
===Test Buzzer===
 +
Jump the buzzer to "ON" and run the following commands:<br>
 +
<syntaxhighlight lang="bash">
 +
$ cd /modules
 +
$ insmod matrix_pwm.ko
 +
$ matrix-buzzer
 +
</syntaxhighlight>
 +
Here is what you expect to observe:<br>
 +
[[File:matrix-buzzer_result.png|frameless|600px|matrix-buzzer_result]] <br>
 +
You will hear the buzzer beeping and the PWM's default frequency is 1KHz and the duty cycle is 50%.

 +
$ echo 60 > export
 +
$ echo out > gpio60/direction
 +
$ echo 1 > gpio60/value
 +
</syntaxhighlight>
 +
"1" turns on LED1 and "0" turns off LED1.

$ cd /sys/class/gpio/
 +
$ echo 74 > export
 +
$ echo in > gpio74/direction
 +
$ cat gpio74/value

===Test AD===
 +
Run the following command to get Channel 0's value:
 +
<syntaxhighlight lang="bash">
 +
$ cd /modules

 +
===Test Compass===
 +
Run the following command to activate the compass:
 +
<syntaxhighlight lang="bash">
 +
$ matrix-compass

</syntaxhighlight>
 +
When you change the module's direction you will get a changing value. Here is what you should expect:<br>

 +
===Test Temperature Sensor===
 +
 
 +
Run the following commands to test the temperature sensor:
 +
<syntaxhighlight lang="bash">
 +
$ cd /modules
 +
$ insmod w1-gpio.ko
 +
$ insmod w1-gpio-board.ko gpio=72
 +
$ matrix-temp_sensor
 +
</syntaxhighlight>
 +
gpio=72 means pin GPIOC8 is used. 72 is the index number used in the Linux kernel.<br>
 +
Here is what you should expect:<br>
 +
[[File:matrix-temperature_sensor_result.png|frameless|600px|matrix-temperature_sensor_result]]

 +
Run the following commands to test the IR receiver:
 +
<syntaxhighlight lang="bash">
 +
$ cd /modules
 +
$ insmod matrix_ir_recv.ko gpio=92
 +
</syntaxhighlight>
 +
gpio=92 means pin GPIOC28 is used. 92 is the index number used in the Linux kernel.<br>
 +
After the driver is successfully loaded a device node will be generated under /dev/input/. We assume it is event1 in our example.<br>
 +
 
 +
An open source utility "input-utils" can be used to read a device's data. Here is how to do it:<br>
 +
<syntaxhighlight lang="bash">
 +
$ apt-get install input-utils
 +
$ input-events 1
 +
</syntaxhighlight>
 +
"1" stands for device node event1.<br>
