Raspberry PI:

Support of RaspBerry PI hardware

 

Since end 2015, the ArcheryClock is also available for RaspBerry PI.

The Raspberry Pi is a low cost, credit-card sized computer that plugs into a computer monitor or TV, and uses a standard keyboard and mouse.The ArcheryClock Software requires a Raspberry Pi version 2 or RaspberryPi version 3. The performance of an older type of Raspberry Pi is not good enough for a qualified accuracy of the timing.

 

Installing the ArcheryClock software on Raspberry Pi is easy by downloading an image file with operating system and ArcheryClock installed. Operating system is Linux. It is installed in such a way that the system starts up with the ArcheryClock program activated.

 

Additionally it is possible to use the interface pins (GPIO). to controll the software with external buttons. and/or using external trafic lights.

 

Installing on Raspberry Pi

Get the image file

Installing the software on Raspberry Pi is via an image file on a microSD card. To get the image file, sent a mail to rpi@archeryclock.com. (The file is 3GB so it needs to be sent via Large file transfer).

 

The file received is a zip file. Unzip the file to get the .img file (Filesize 8GB).

Write the image file to the SD card.

 

An SD card of 8GB is needed. To write the file to the SD card you need a program like Win32 Disk Imager.

Some 8GB micro SD cards are too small for the image file. So if you still need to buy one, buy a 16GB card. (Class 10)

 

Put the micro SD card in the Raspberry Pi. Your system is ready.

 

Finally, put the micro SD card in the Raspberry Pi. Power on. And your basic system is ready.

Optionally, the GPIO pins can be used for external controll buttons.

 

See connections for GPIO in next table:

 

(outputs is 3.3Volt when active. 0 Volt when inactive.)

(inputs, use connection to 3.3 volt to activate. And pull down resister of 1K ohm)
