Introduction
Prerequisites
Change the default password
For maximum security, change the password for the default user 'pi'
> passwd
and specify a new, secure password.
Configure Raspberry Pi base settings
Enable WiFi
Enable and configure WiFi per the official documentation
(Optional) Enable SSH
You can optionally enable SSH for remote management from the comfort of your main computer's keyboard and screen.
Enable and configure ssh per the official documentation
Install multi-touch tools
Install the packages that enable multi-touch interfaces.
> sudo apt-get install mtdev-tools
Configure memory split
You'll need to bump up the memory made available to the GPU. Increase the default value of 64 to 256.
- Via raspi-config tool
You can adjust the memory split by running the raspi-config tool. See the official documentation
- Editing /boot/config.txt
You can adjust the value directly by editing the /boot/config.txt file.
> sudo nano /boot/config.txt
Find the line containing gpu_mem=64 and change the number to 256
gpu_mem=256
Installing the RaceCapture app package
Download the latest RaceCapture app package and place it in the /opt/ directory of the Raspberry Pi.
- Directly downloading to the Raspberry Pi
You can download it directly by getting the URL of the package by right-clicking the download link and copying the URL to your clipboard. Then, use it in the command below:
cd /opt sudo wget <package URL>
Extract the package
Now extract the downloaded package :
sudo tar -xjvf <downloaded file>
Launch the app
Launch the RaceCapture app by running the following command:
/opt/racecapture/run_racecapture.sh
Launching with Watchdog
You can launch the RaceCapture app with an automatic watchdog that re-launches the app in case a crash occurs.
/opt/racecapture/run_racecapture.sh -w 1
- Note: to break out of the watchdog loop, press ctrl-z to suspend the app, then issue:
killall -9 run_racecapture.sh
