Hi. Please can you post the schematic of the 4 (or more) daisy chained LM3914? Thanks…
I am struggling with the function R(adj). Why is it sometimes tied to ground and other it has a voltage divider? Also in the cascading example it seems that the R(hi) is tied to ground on the bottom chip, and it sends its R(Lo) to the other chip.
How were you able to connect the bar graphs to the power rail and keep them next to each other? When I try it there is a gap between them.
Heh, yeah…darn that gap. I ended up bending the legs that hit the gap 90° over, and wrapping them around the next leg over (for a temporary solution, soldering for more permanent).
