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.
File-In image select the image downloaded and decompressed Raspbian.
- In Device select the drive where the SD memory is.
We Power-Write.

We insert the SD in Raspberry and fed by the USB cable. After two minutes, run Putty.
-In Host Name put: raspberrypi
-De not work well the previous step, go to the router and find the IP assigned to your RaspberryPi.
-We marked SSH.
-We Power Open.

We request Login. According Raspbian the user is "pi" and the password "raspberry" (Both without quotes).
We 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 need to be root (sudo-s):

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