Displaying the current stage number in automation?

[Tobruk]

Could someone help me with the signal counter to display the current power stage of my system? As you can see there are four stages.

In terms of its behaviour, I think I have it figured out, but I'm having trouble transferring this into automation. What I was thinking is sending X green ticks depending on how many bits are green (four, three, two or just one, respectively for stage 4, 3, 2, 1), and resetting the counter if there's a negative/positive edge for either of the battery (stage has changed), and send the ticks corresponding to the stage again, so it would count them once more.

Maybe easier with a pixel pack?

Signal switches represent the battery stages.

Buffers and filters set to 0.2 seconds each followed by XOR to identify rising and falling edge of each stage.

The rising/falling edge pulse resets the counter.

The pulse then drives buffers of 0.4 seconds each. NOT a pulse AND a buffered pulse creates another falling edge signal. The subsequent filter ensures we have some space between our falling edge pulses. Essentially this mess creates a set of 4 pulses, each 0.2 seconds in length and spaced 0.2 seconds apart.

AND each of those subsequent "stage pulses" with the stage itself. If a stage is present, then the counter will increase.

Tested and works. It takes 1.8 seconds to count up to the current stage. I cannot guarantee this will work correctly if the stage changes within this 1.8 seconds.

You may be able to speed this up; I do not know. There are probably also ways to simplify. I would be interested to see if anyone has any suggestions for improvement.
