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

Installation

Run win32diskimage.
- In "Image file" select the Raspbian image downloaded and decompressed.
- In "Device" select the drive where the SD memory is.
- Select "Write".

Insert the SD in Raspberry fed by the USB cable. After two minutes, 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.

It will request a Login. According Raspbian the user is "pi" and the password "raspberry" (Both without quotes).
Insert the following commands:

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):

# sudo-s
# Jaispi-i / dev/spidev0.0
