2. Enabling I2C and SPI, which is only required to be done **once** for **each** Raspberry Pi:\
|
||||
**Only Required if you are using multiple devices on your Raspberry Pi, if not, move to step 3**\
|
||||
**Important:**
|
||||
> If you are using a GPIO wiring setup for the LEDs that does not support I2C, you will not see anything show up for the LEDS.\
|
||||
Again, this is only for if you have **OTHER** devices you plan on hooking up to make sure they still show up under I2C\

|
||||
> Again, this is only for if you have **OTHER** devices you plan on hooking up to make sure they still show up under I2C\
|
||||
* Enabling I2C:
|
||||
* From Command Line:
|
||||
```
|
||||
sudo apt-get install -y python-smbus
|
||||
sudo apt-get install -y i2c-tools
|
||||
sudo raspi-config
|
||||
```
|
||||
* Interfacing Options > I2C > Enable > Yes
|
||||
> If you did not hit "finish" you can repeat these steps but change out the I2C for the SPI
|
||||
* From Command Line:
|
||||
```
|
||||
sudo apt-get install -y python-smbus
|
||||
sudo apt-get install -y i2c-tools
|
||||
sudo raspi-config
|
||||

|
||||
* Interfacing Options > I2C > Enable > Yes
|
||||
> If you did not hit "finish" you can repeat these steps but change out the I2C for the SPI
|
||||
* Enabling SPI:
|

* From Command Line:
|
||||

|
||||
sudo raspi-config
|
||||
```
|
||||
* From Command Line:
|
||||
```
|
||||
sudo raspi-config
|
||||
```
|
||||
* Interfacing Options > SPI > Enable > Yes
|
||||
* Click "Finish"
|
||||
* Reboot your Raspberry Pi
|
||||
```
|
||||
```
|
||||
sudo reboot
|
||||
```
|
||||
* Testing I2C and SPI after reboot:
|
||||
* I2C Testing:
|
||||
```
|
||||
sudo i2cdetect -y 1
|
||||
```
|
||||
* If you do not get anything back from the above command, try seeing which I2C is being used under Dev:
|
||||
```
|
||||
ls /dev/i2c*
|
||||
```
|
||||
> whichever number is after the "-" in "/dev/i2c-(X) is what you should replace the number in the command with
|
||||
>> Example: /dev/i2c-3 = "sudo i2cdetect -y 3"
|
||||
* SPI Testing:
|
||||
```
|
||||
ls -l /dev/spidev*
|
||||
```
|
||||
> This should return a device for each SPI bus (two)
|
||||
* I2C Testing:
|

3. Installing Python Support Libraries:
|
||||
* GPIO - If not already installed:
|
||||
```
|
||||
sudo pip3 install RPI.GPIO
|
||||
```
|
||||
* Adafruit Blinka:
|
||||
```
|
||||
sudo pip3 install adafruit-blinka
|
||||
```
|
||||
* RPi WS281X and Neopixel:
|
||||
```
|
||||
sudo pip3 install rpi_ws281x adafruit-circuitpython-neopixel
|
||||
sudo python3 -m pip install --force-reinstall adafruit-blinka
|
||||
```
|
||||
* PixelFramebuffer:
|
||||
```
|
||||
sudo pip3 install adafruit-circuitpython-pixel-framebuf
|
||||
```
|
||||
* GPIO - If not already installed:
|
||||
```
|
||||
sudo pip3 install RPI.GPIO
|
||||
```
|
||||
* Adafruit Blinka:
|
||||
```
|
||||
sudo pip3 install adafruit-blinka
|
||||
```
|
||||
* RPi WS281X and Neopixel:
|
||||
```
|
||||
sudo pip3 install rpi_ws281x adafruit-circuitpython-neopixel
|
||||
sudo python3 -m pip install --force-reinstall adafruit-blinka
|
||||
```
|
||||
* PixelFramebuffer:
|
||||
```
|
||||
sudo pip3 install adafruit-circuitpython-pixel-framebuf
|
||||
```

||||
4. Changing Conflicting HDMI Settings:\
|
||||
**Important:** Only do this if you are having issues with the LEDs, this is not always needed!\
|
||||
```
|
||||
sudo nano /boot/config.txt
|
||||
```
|
||||
* If it doesn't already exist, add:
|
||||
```
|
||||
hdmi_force_hotplug=1
|
||||
hdmi_force_edid_audio=1
|
||||
```
|
||||
* Save and exit the file (ctrl + x > y)
|
||||
* Reboot Raspberry Pi
|
||||
```
|
||||
