TftSignalSet()

Syntax

TftSignalSet(bActiveBars As Byte)

Parameters

bActiveBars — new number of lit bars, 0 to bBarCount (clamped)

Efficiently updates an already-drawn TftSignalIcon()'s active-bar count

Efficiently updates an already-drawn TftSignalIcon()'s active-bar count, redrawing only the bars whose lit/unlit state actually changed - not the whole icon.
Reads geometry/colors directly from TftSignalIcon()'s own last-used parameters.

Requires TftSignalIcon() to have been called at least once first - this function has no way to detect that on its own.
