PiGlow Top is a real-time CPU utilization monitor for the Raspberry Pi 2 that displays its output on a PiGlow.

PiGlow Top accepts two parameters:

• brightness: LED brightness

  This is the percentage of max LED brightness (between 0 and 1.0).

• period: CPU poll period (in milliseconds)

  This is how often CPU utilization info is gathered from the system (i.e. how quickly the PiGlow is updated).
