| 6 | 16 | SCLK | 23 | Clock Input |
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[edit | edit source]
Installing Raspbian[edit | edit source]
Run win32diskimage (if you use linux you can use dd)
- In "Image file" select the downloaded and decompressed Raspbian image (2013-09-25-wheezy-raspbian.img at the time of this writing)
- 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[edit | edit source]
Two minutes after booting up the Raspberry Pi, run Putty.
- 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, - Select SSH (or Raspberry and Putty support TTL https://learn.adafruit.com/adafruits-raspberry-pi-lesson-5-using-a-console-cable/overview)
- Select Open
Installing Application[edit | edit source]
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/raspi-blacklist.conf echo "blacklist i2c-bcm2708" >> /etc/modprobe.d/raspi-blacklist.conf 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
Options[edit | edit source]
