# FPIOA Example

## Overview

This sample dumps the current board-level FPIOA configuration and generates reusable pinmux configuration snippets.

Source file: `src/rtsmart/examples/peripheral/fpioa/test_fpioa.c`

## What It Does

- Reads the configuration of `IO0..IO63`
- Infers the voltage domain by bank
- Prints a `board_pinmux_cfg` array that can be reused in board code
- Warns when inconsistent bank settings are detected

## Key APIs

- `drv_fpioa_get_pin_cfg()`
- `drv_fpioa_get_pin_func_name()`

## Build and Run

```shell
cd src/rtsmart/examples/peripheral/fpioa
make
./test_fpioa
```

The sample has no command-line parameters.
