Joy-Pi.zip Also, if you are using your own image, you need to enable I2C. To do this, enter the following command in the terminal: sudo raspi-config Now go to 3Interfacing Options and enable I5 I2C. www.joy-it.net Pascalstr. 8 47506 Neukirchen-Vluyn... - Page 4 Since all pins of the Raspberry Pi are used in the JoyPi, you can only use the pins that you can disconnect using the two switching units of the Joy- Pi. These are highlighted in the diagram above. In addition, pins 3 and 5 can be used for I2C communication. www.joy-it.net Pascalstr. 8 47506 Neukirchen-Vluyn...
