This example shows how to control a user LED (LED3):

This example shows how to read the state of a button:

The only onboard button connected to a GPIO is the boot button, wired to P8_43. So you have to adapt #define PIN P8_43. And since the button switches GND, you should use a pull-up resistor: if (pruio_gpio_config(io, PIN, PRUIO_GPIO_IN_1)) {…

Merge both examples together and off you go.
