Why
Dragon Q8B's pin-gpio guide previously only listed tool installation and GPIO controller identification steps. This PR expands the GPIO Usage section to match the structure of the Dragon Q6A guide, with example pins and code adapted to the Dragon Q8B hardware:
The example follows the Q6A output/input loopback test flow (hardware prep, python-periphery, test code, test steps, expected results). The GPIO controller on Dragon Q8B was confirmed internally as
/dev/gpiochip4, and the line offsets correspond to the GPIO numbers listed in the Q8B pinout table.Changes
