AM261x MCU+ SDK: GPIO Input Interrupt

| AM261x MCU+ SDK 26.00.00 |

GPIO Input Interrupt

# Introduction

This example configures a GPIO pin in input mode and configures it to generate interrupt on rising edge. The application waits for 5 key presses, prints the number of times the keys are pressed and exits.

# Supported Combinations

Parameter | Value
--- | ---
CPU + OS | r5fss0-0 nortos
Toolchain | ti-arm-clang
iar-arm
Boards | am261x-som, am261x-lp
Example folder | examples/drivers/gpio/gpio_input_interrupt/

# Steps to Run the Example

- When using CCS projects to build, import the CCS project for the required combination and build it using the CCS project menu (see Using SDK with CCS Projects).
- When using IAR EW projects to build, import the IAR EW workspace for the required combination and build it using the IAR EW project menu (see Using SDK with IAR Embedded Workbench Projects).
- When using makefiles to build, note the required combination and build using make command (see Using SDK with Makefiles)
- Launch a CCS or IAR EW debug session and run the executable, see CCS Launch, Load and Run or IAR Launch, Load and Run
