Setting SymbPins in 4 digit common cathode sev-seg with AP and COLON

Open minolmal opened this issue 5 years ago • 0 comments

I understand that you cannot make a universal library where each and every device would work with. (given time and support from community, maybe).

My 4 digit CC 7-seg with AP and Colon has 12 pins. 7 for A-G segment pins (positive supply or GND) 4 for digit 0-digit 3 digit pins (negative supply) device pin num 3 for AP and COLON (positive, of course)

I have attached a partial diagram to clarify above details. please, mind that rest of the display works fine just as a normal SS_colon_pin_diagram

CC 7-seg display.

after probing through pins, I found out when digit 2 pin and AP/COLON pin activated, AP lights on when digit 3 pin and AP/COLON pin activated, COLON lights on

I tried with disp.setColonPin(int colonPin). disp.setColonPin(3);

I tried with disp.setSymbPins(int digPin, int segUCPin, int segLCPin, int segAPIN). disp.setSymbPins(9, 3, 3, 3);

both will not turn off colon or AP as CC mode will, in off state, supply correct biasing thus turning LEDs on.

Have I missed something? Is there any simple work around that I can use to overcome this?

I have read through included pdf guide (SevenSeg.pdf)
