In pcDuino, there are two flavors to write program to control hardware, command-line and QT GUI. In this post, we go through the first one: command-line program.
To make things simple, we use a virtual box on a windows PC to install 64-bit Ubuntu PC. So all the work done below is on a 64 bit machine if it is done on a X86 PC.
Step 1: Download source code (including 64-bit arm toolchain for android)
$ git clone https://github.com/liaods/c_enviroment_android.git
Step 2: Modify \c_enviroment_android\Makefile(The Make file is for qt-android APK by default, do a little change for command line program).
- Change CFLAGS from “CFLAGS = -fPIC -DQT_ANDROID” to “CFLAGS = -fPIC”
- Uncomment the line “make -C sample’.
Step 3. Run build script to build the samples ( target is output/test under c_enviroment_android )
Step 4: Copy the output on output/test to pcDuino by using OTG port or SD card.
The toolchain included is 64-bit, if your machine is 32-bit, you need to generate the toolchain by yourself.
Download android ndk and run:
$./build/tools/make-standalone-toolchain.sh --platform=android-14 --system=linux-x86
