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
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:
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
Options
