Using an LCD on the Edison
Shawn Hymel 
Install the ILI9341 Module
Flash and Configure the Edison
If this is your first time using the Edison, it is recommended that you update to the latest firmware and connect to WiFi.
Build MRAA
MRAA is Intel's set of libraries used to control the low-level hardware. Because UPM relies on MRAA, we need to install it first.
Connect to the Edison over Serial or SSH. Once logged in, enter the following commands to download MRAA:
wget https://github.com/intel-iot-devkit/mraa/archive/master.zip
unzip master.zip
mv mraa-master mraa
Then, build MRAA with:
cd mraa
mkdir build
cd build
cmake ..
make
Install the newly built libraries, and update the pkg-config path, which is needed by UPM.
make install
export PKG_CONFIG_PATH=$PKG_CONFIG_PATH:/usr/local/lib/pkgconfig
Build ili9341 in UPM
Next, we need to download the latest version of UPM and install the ili9341 module. Download UPM with:
cd ~
rm master.zip
wget https://github.com/intel-iot-devkit/upm/archive/master.zip
unzip master.zip
mv upm-master upm
Prepare to build:
cd upm
mkdir build
cd build
cmake ..
Build and install the ili9341 module:
make ili9341
cd src/ili9341
make install
And that's it! We'll use this installed library to make an example program that draws some basic shapes on the LCD. Choose whether you want to write the example program in C++, JavaScript, or Python, and skip to that section below.
