I made an extended range VU meter like in the LM3915 data sheet (the exact same one) the only difference is that the pot is a 20k pot. The "upper" VU chip won't display in bar mode, only dot mode even though pin 9 is connected to V+
Why can't I get it to change? I know it's not the chip because I tried with 3 different VU meters and they all worked in bar mode for the lower segment but they all displayed in dot mode for the upper portion.
