This example is deprecated. The mbed-os-example-cpu-stats example shows how to use the mbed_stats_cpu_get API to print the CPU usage.
This guide reviews the steps required to get CPU usage on Mbed OS platform.
Please install mbed CLI.
From the command-line, import the example:
mbed import mbed-os-example-cpu-usage
cd mbed-os-example-cpu-usage
Invoke mbed compile, and specify the name of your platform and your favorite toolchain (GCC_ARM, ARM, IAR). For example, for the ARM Compiler 5:
mbed compile -m K64F -t ARM
Your PC may take a few minutes to compile your code. At the end, you see the following result:
