4 Download Matrix Source Code
All the matrix modules' code samples are open source. They are maintained on GitHub - git://github.com/friendlyarm/matrix.git
Each branch in this hub contains the matrix modules' code samples for a board that the matrix modules can work with。
- The nanopi branch contains the matrix modules' code samples for the NanoPi
- the tiny4412 branch contains the matrix modules' code samples for the Tiny4412
- the raspberrypi branch contains the matrix modules' code samples for the RaspberryPi
Please follow the steps below to get the source code:
Install the git utility on a PC running Ubuntu14.04
$ sudo apt-get install git
Clone the matrix code from GitHub
$ git clone git://github.com/friendlyarm/matrix.git
If this is successful a "matrix" directory will be generated, which will contain all the matrix modules' code samples.
5 Connect to NanoPi
5.1 Preparations
Please install a Debian on a NanoPi and an appropriate cross compiler on a PC. Please refer to wiki:NanoPi
Compile a NanoPi kernel. Note: please use the kernel's source code from the nanopi-v4.1.y-matrix branch.
$ git clone https://github.com/friendlyarm/linux-4.x.y.git $ cd linux-4.x.y $ git checkout nanopi-v4.1.y-matrix $ make nanopi_defconfig $ touch .scmversion $ make
5.2 硬件连接
参考下图连接模块Matrix-SPI_TFT和NanoPi
Matrix-SPI_TFT_nanopi
连接说明：
| Matrix-SPI_TFT | NanoPi |
5.3 加载驱动模块
启动NanoPi，在其Debian的shell终端上加载芯片对应的驱动模块
$ modprobe fbtft_device name=matrix-spi_tft gpios=dc:161,reset:162,cs:163 $ modprobe matrix_ads7846
模块fbtft_device是芯片ili9341的驱动，模块matrix_ads7846是芯片xpt2046的驱动
5.4 安装软件包
在NanoPi的shell终端上安装软件包qtembedded和matrix-tslib
$ apt-get update $ apt-get install qtembedded $ apt-get install matrix-tslib
qtembedded是qt相关的库，matrix-tslib则用于触摸屏校准。
5.5 运行测试程序
启动Qt应用程序
$ . /usr/bin/matrix-setqt4env $ /usr/local/Trolltech/QtEmbedded-4.8.5-arm/examples/tetrix -qws
matrix-setqt4env用于设置环境变量，第一次运行该脚本时，会出现触摸校准的界面，根据提示点击5个点后完成校准。 tetrix是一个qt4编写俄罗斯方块小游戏，点击start按钮后就可以开始娱乐了。
