1. An SD card larger than 1G (used to install Debian on the DragonBoard 410c);
2, DragonBoard410C
3, HDMI cable
4, a set of USB keyboard, USB mouse
5, one U disk (greater than 256MB)
6, a display with HDMI
Note: Do a backup of the SD card, because we will use the win32diskimager to format the operation.
The first step is to install Debian.The process of installing Debian can refer to the following steps:
Note: Do not connect the expansion IO board and associated sensor to the DragonBoard 410c during installation.
1.1 Download the Debian imageOpen the page https://builds.96boards.org/snapshots/dragonboard410c/linaro/debian/84/
In this page, dragonboard410c_sdcard_install_debian-84.zip is the Debian image package we want (this step, we only download this package), after downloading it, unzip it, we will get the db410c_sd_install_debian.img file, this is what we want to brush Go to the Debian image in the SD card.
Here is a brief explanation, in fact, in https://builds.96boards.org/snapshots/dragonboard410c/linaro/debian/
We can see that this suite has been kept up to date, and latest is the Debian image of the latest suite.
1.2 Format the USB flash drive and copy related filesFormat the U disk, format the configuration, you need to set the U disk name to DRAGON (note, we will use this name later, so be sure to do DRAGON do not make mistakes), then copy our breakerball.tar and Install files In the formatted U disk, we can unplug the U disk.
1.3 Making a Debian SD Installation DiskYou can go online to download WinDisk32Imager.exe, you can refer to the following address:
Https://sourceforge.net/projects/win32diskimager/
1.3.1 Inserting SDCard
1.3.2 Using WinDisk32Imager for System Image Programming
Please refer to the following figure for Debian system image burning, select the decompressed db410c_sd_install_debian.img, Device select our SD card, pay attention to not choose the wrong here.
figure 1
Then click on write. (It will be ok in about 5 minutes).
1.4 DragonBoard 410c image burningAfter safely removing the SD card, insert it into the DragonBoard, turn the DIP 2 (SD Boot) dial switch of the DragonBoard 410c to ON, and keep the other switches OFF. At the same time, plug the USB mouse and keyboard set into the DragonBoard port and connect the DragonBoard to the HDMI display device with an HDMI cable.
Plug in the power supply of the DragonBoard and enter the installation interface in about 15s.

Press i, then press Enter

Installation in progress
Figure 4
After the installation is complete, you will be prompted to unplug the SD card. At this time, we unplug the power supply, then remove the SD card, and turn the DIP 2 (SD Boot) dial switch of the DragonBoard 410c to OFF, and then plug in the power again. .
The second step is how to use DragonBoards to run BreakerBall Game 2.1 hardware connectionWe connect the IO board and sensor to the 410C. Note that the correct connection must be made here. The wrong connection may cause both boards to burn out.
Connect the rotary angle sSnapdragon VR SDK Graphics path IntroducedTIonensor to the A1 interface
Connect the 1602 LCD to the I2C0 interface. For the connection method, refer to the following figure:
2.2.1 Plug in the power and enter Debian
2.2.2 Connecting to the Internet
SetTIngs --> Wifi connecTIon Connect to an available network (this is for downloading related programs from the internet when apt-get).
2.2.3 Running Install
Open a command window:
Debian Start -> System Tools -> LXTerminal
carried out:
Cp /media/linaro/DRAGON/*.
Chmod +x Install
./Install
The script extracts the zip file, then places the icon on the desktop and loads the code into the IO board while updating the operating system.
When the script finishes executing, we can see the BreakerBall icon as shown below:
2.2.1 Plug in the power and enter Debian
2.2.2 Connecting to the Internet
SetTIngs --> Wifi connection Connect to an available network (this is for downloading related programs from the internet when apt-get is later).
2.2.3 Running Install
Open a command window:
Debian Start -> System Tools -> LXTerminal
carried out:
Cp /media/linaro/DRAGON/*.
Chmod +x Install
./Install
The script extracts the zip file, then places the icon on the desktop and loads the code into the IO board while updating the operating system.
When the script finishes executing, we can see the BreakerBall icon as shown below:
Figure 6
Double-click the BreakerBall icon, you will be prompted where you want to execute, and choose whichever.
Figure 7
When the scratch tool is started, if the remote sensor is running normally, click OK.
Click on the green flag in the middle of the middle and the game will start.
Figure 8
When the rotary angle sensor is adjusted, the real-time position information will be displayed on the 1602 LCD screen, and the purple stick that bounces the breakerball will move with it.
Figure 9
Click the full-screen icon in the upper right corner of the scratch to display the full screen. You have 15s to execute the above steps. If it exceeds 15s, the program will automatically read the value of the rotary sensor and transmit the position information of the "board".
The overall effect is this, So easy! ! !
