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

newer Raspberry Pi model B+ and Raspberry Pi model A+ both use same pinout for the first 26 pinheaders as the previous nonplus model, so it should work on that as well.

Installation

Installing Raspbian

Run win32diskimage (if you use linux you can use dd)

1. In "Image file" select the downloaded and decompressed Raspbian image (2013-09-25-wheezy-raspbian.img at the time of this writing)
2. In "Device" select the drive where the SD memory is.
3. 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.

1. In Host Name put: raspberrypi
   If this doesn't works properly, go to the router, find the IP assigned to your Raspberry Pi and use that instead,
2. Select SSH
3. 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:

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 Raspberry Pi. To run the command jaispi you need to be root (sudo-s):

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