Task Load Reporting

Track idle time and task activity so CPU load trends can be observed while demos run.

Board LPCXpresso51U68 EVB OM40005
Status Planned
Download cleveros_task_load_demo.c

Run It

Use these commands from the COS workspace when the board and serial adapter are attached.

make -C firmware/lpc51u68_cleveros_load_demo clean allmake -C firmware/lpc51u68_cleveros_load_demo flashpython3 tools/uart_viewer.py --device <serial-device> --baud 9600

What To Look For

  • Idle task maintains a baseline counter.
  • Each task records activation count.
  • The report task prints a stable one-second summary.
