SBUS Example

Overview

This sample sends SBUS frames through UART3 and changes channel values dynamically when a button is pressed.

Source file: src/rtsmart/examples/peripheral/sbus/test_sbus.c

Default Mapping

• GPIO21 as button input

• PIN50 -> UART3_TXD

• PIN51 -> UART3_RXD

Key APIs

• drv_fpioa_set_pin_func()

• drv_gpio_inst_create() / drv_gpio_value_get()

• sbus_create() / sbus_destroy()

• sbus_set_channel() / sbus_send_frame()

Build and Run

cd src/rtsmart/examples/peripheral/sbus
make
./test_sbus

The sample has no command-line parameters.
