1. PURPOSE / DESCRIPTION
1.1 Set up the development environment of BrainBox
- DRONA
- WiRa (drone APP and client APP)
1.2 Demonstrate how to use Vairdo Binox APP (client APP)
2. TEST SET-UP
2.1 DRONA
- MPLAB X IDE v2.15
- MPLAB ICD 3
- DRONA Firmware: https://github.com/Vairdo/DRONA_firmware, version: 816ee47
2.2 WiRa
- Download the Brainbox App Apk file and install it.

| Step 7 |
3.2 Install the compiler if there is no XC16 in your computer (XC16 v1.21)
3.2.1 Please note that the version must be v1.21. For the latest version, the paths of the libraries have been modified, which may cause build error in the firmware.
3.2.2 For the old versions of XC16, Microchip only provides the shell scripts for installation. It is easier to install XC16 with executable file.

3.3.1 Please follow the procedures below:
 |
 |
| Step 1: Open Project | Step 2: Double click Selfie_Drone.X |
 |
|
| Step 3: Select the 3rd icon to flash the code only; the 6th icon to enter debug mode (both would build code before processing) | |
 |

| Step 4: Remember to connect ICD 3 to PC | Step 5: Note the connecting direction |
3.4 Other configuration
3.4.1 Select Menu bar -> File -> Project Properties
 |

 |
| Make sure the compiler is the same as above; otherwise it may cause build error |
3.5 Install Android Studio
3.5.1 Install tutorial link
3.6 Open project:
 |
 |
| Step 1: Menu bar -> Open | Step 2: choose SelfieDrone Project |
 |
|
| Step 3: Wait until build is finished | |
