60ma. overload occurs whenever I call for a decimal point (true) regardless of char value
lc.setChar(0,0,'char value',true);
I would expect the char "8" [all segments ON] would consume more MA than a smaller single decimal point(s)?
SEG DP #22 seems to be .32V whenever any lc.setChar call is made
setting intensity low doesn't help
Is there a question here?
Do you have a schematic? The part works nicely if you have a display wired per the datasheet.
perhaps I don't have it wired correctly ?
led display is a LITE-ON LTD-5623BG -- https://www.jameco.com/Jameco/Products/ProdDS/2005358.pdf
2 segment led module DP pins #9 & #4 wired in parallel to SEG DP #22
Digit 1 common collector to DIG0
Digit 2 common collector to DIG1
have tried wiring only single DP and other identical LTD-5623 with same overload result
So you have the displays eight A-G+DP pins connected to each other, going to the SEGa-SEGg+DP pins on the 7219, and 13s & 14s going to DIG0, DIG1, DIG2, DIG3?
perhaps I don't have it wired correctly ?
Perhaps.

yes 7219 is wired as stated
DO & D1 are the only digit drive lines connected
I'm not sharp enough to utilize code as provided as I immediately run into errors such as SS undefined.
do I need to include another SPI library?
