The BitWizard DMX interface is an HAT (hardware attached on top) extension board for the Raspberry Pi [1].
Installation Notes
GPIO Configuration
For the BitWizard HAT to function it has to be set to output mode via the GPIO [2] pins. There are a number of programms which enable you to configure the GPIO pins. In this example we use pigpio [3]. To install pigpio on your Raspberry Pi either open a terminal window or connect to the Pi via SSH and type:
sudo apt install pigpio
Output mode
Then we create a shell script [4] which will configure the GPIO pins when we run the script. Let's call the script bitwizard_gpio.sh
#!/bin/bash pigpiod sleep 1 pigs m 18 W pigs w 18 1 pigs m 14 0 pigs m 15 0 systemctl restart olad
Caveat: We presume your shell is Bash [5]. If you use another shell change the first line of the script accordingly. We also presume that you have either Open Lighting Architecture (OLA) [6] or QLC+ [7] installed on your Raspberry.
Then make the script executable:
sudo chmod +x bitwizard_gpio.sh
Run the script with:
sudo ./bitwizard_gpio.sh
Now the pin configuration is changed and the BitWizard DMX HAT should work.
