Use short wires, esp. if you are not adding the 0.1{{micro}}F capacitor between ground and vcc as close as possible to the chip


=== Installation ===

==== Installing Raspbian ====
 Run win32diskimage.
 - In "Image file" select the downloaded and decompressed Raspbian image.
 - In "Device" select the drive where the SD memory is.
 - Select "Write".
After finished writing, put the SD card in the Raspberry Pi and power it up by inserting the USB cable.

==== Remote Shell into Raspbian ====
 Two minutes after booting up the Raspberry Pi, run Putty.
 -In Host Name put: raspberrypi
 -In case the previous step doesnt works properlly, go to the router and find the IP assigned to your RaspberryPi.
 -Select SSH.
 -Select Open.

==== Installing Application ====
 It will request a Login. According Raspbian the user is "pi" and the password "raspberry" (Both without quotes).
 Insert the following commands:
{{keyboard|content=
sudo-s
cd /bin
wget http://jaicrab.org/Ps4/Tools/JAISPI/jaispi
chmod +x jaispi
echo "# blacklist spi-bcm2708"> / etc / modprobe.d / blacklist.conf raspi-
echo "blacklist i2c-bcm2708" >> / etc / modprobe.d / blacklist.conf raspi-
reboot
}}

Installation is complete. By Putty you can access the RaspberryPi. To run the command jaispi you need to be root (sudo-s):
{{keyboard|content=
# sudo-s
# Jaispi-i / dev/spidev0.0
}}
