FPIOA Example

Introduction

This example is used to export the current board-level FPIOA configuration and automatically generate reusable pinmux configuration code snippets.

Source code location: src/rtsmart/examples/peripheral/fpioa/test_fpioa.c

Example Behavior

• Read the register configuration of IO0..IO63

• Infer the voltage domain by bank (BANK_VOL_1V8_MSC / BANK_VOL_3V3_MSC)

• Output the board_pinmux_cfg array (can be directly used in board-level configuration code)

• Issue warnings for abnormal configurations (e.g., inconsistent msc within a bank)

Key Interfaces

• drv_fpioa_get_pin_cfg()

• drv_fpioa_get_pin_func_name()

Build and Run

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

This example has no command-line arguments, and the result is output to standard output.

Tip

For FPIOA interface description, please refer to the FPIOA API Documentation.
