Installation

Installing this Kernel Module on a Raspberry Pi is quite straight forward.

• sudo apt-get update && sudo apt-get upgrade -y && sudo apt-get install git raspberrypi-kernel-headers
• git clone https://github.com/arturo182/bbq10pmod_module.git && cd bbq10pmod_module
• make && make dtbo
• sudo cp bbq10pmod.ko /lib/modules/4.19.57+/kernel/drivers/i2c/bbq10pmod.ko
• sudo cp i2c-bbq10pmod.dtbo /boot/overlays/
• sudo sh -c "echo dtoverlay=i2c-bbq10pmod >> /boot/config.txt"
• sudo sh -c "echo bbq10pmod >> /etc/modules"
• sudo depmod
• sudo reboot

After these steps you should have the PMOD working on your Raspberry Pi. You can check this via dmesg:
