Goal: Interface hardware peripherals (sensors, actuators, radios) with a Raspberry Pi running a standard Linux OS (Raspberry Pi OS).
The 40-pin GPIO header provides multiple buses.
raspi-config. Built-in pull-up resistors (1.8kΩ) exist on these pins./dev/serial0 (disables Bluetooth console on Pi 3/4).Prefer gpiozero for simple UI/sensors and smbus2 or spidev for deep bus control.
sudo apt install i2c-tools
i2cdetect -y 1
from smbus2 import SMBus
with SMBus(1) as bus:
# Read a byte from device 0x48, register 0x00
b = bus.read_byte_data(0x48, 0)
