## Summary
After the initial RV1103 setup, this part walks through LED blinking and GPIO control with several practical approaches.

## Body
GPIO on RV1103

This note continues from the initial Luckfox Pico setup and focuses on controlling GPIO pins under embedded Linux.

   What it covers

The main example is a blink LED flow, then the same idea is approached through different layers so the behavior is easy to debug and reuse.

   Result

By the end, the board can toggle an external LED and you have a repeatable path for testing other simple digital outputs.
