The reason that my HUD green LED pulses is so I know it isn't frozen. It's a PWM brightness modulation triggered by the watchdog timer.

Funny thing, my HUD has a lot more smarts and electronics than my primary display. My primary display only has 3 - 3 1/2 digit voltmeter modules with 10K pots for calibration and I only use the last 3 digits so I don't need amplifiers. I scale down the cells to 2.1 mV for .21 PO2.
