    thanks dig !
    double click mode change is now working, whatever mode you putbit in, it will stay in until you double click again.
    now working on pwm mode so it will work with stock ego and things like the vmax and jib and give rms readings, not even a multimeter will do that unless you get an exxy true rms meter.
    looking good, working but with a bit of display flicker, it can only drive the seven segment display when the device is driving, so some tricky interrupt work needed to get the display shutoff asap .. 100 uS interrupt latency is starting to annoy me..

    alright !!
    working fine with an ego now, the display flickers, nothing really can be done about that as the source voltage is on and off, rock solid readings and a constant brightness display at least.
    I spent a while trying to remove all display flicker till I sat back and came to the realisation, its simply unavoidable. So went with the ego flow and update a different character on each new pulse.

    was just surprised how much an ego drops under load .. 4.03v in on an open circuit drops to 3.67v driving a 1.5 ohm DC. now to add rms voltage, and duty cycle and frequency measurements.

    quick demo of ego mode, still have some jitter in the PWM duty cycle measurement, 82.5% is correct according to my CRO. When it detects a pwm device it then alternates between battery voltage and rms voltage display. Any jitter in the duty cycle measurement is then carried across into the rms calculations.

    In PWM mode it displays peak current as I think thats more useful than an rms current and true power as peak power is fairly pointless.
