Examples

LED

This code is to blink the D3 LED on the board.

To build the release binary : 

  1. cargo build --release --example leds

In one terminal start openocd : 

  1. openocd

In another terminal start setup gdb to run launch the application : 

  1. arm-none-eabi-gdb -x openocd.gdb target/thumbv7em-none-eabi/release/examples/leds

Button

The code prints the button status onto the console via semihosting.

To build the release binary : 

  1. cargo build --release --example buttons

In one terminal start openocd : 

  1. openocd

In another terminal start setup gdb to run launch the application : 

  1. arm-none-eabi-gdb -x openocd.gdb target/thumbv7em-none-eabi/release/examples/buttons

External interrupts via GPIO ports

This is a little more complicated and fun example. The board has 2 user buttons and 2 user LEDs. The code configures each button to trigger on being pressed, and the interrupt handler toggles a button.

To build the release binary : 

  1. cargo build --release --example leds

In one terminal start openocd : 

  1. openocd

In another terminal start setup gdb to run launch the application : 

  1. arm-none-eabi-gdb -x openocd.gdb target/thumbv7em-none-eabi/release/examples/leds

Note that the gdb configuration has been passed to gdb. But the application is not started on the board, run continue command in gdb to resume execution.
