Need help with programing tm1637 6 digit 7 segment display

[Vinc_Vega]

Hi Hammer,

The above code doesn't include a Preset Channel display.

If you want to have that display e.g. to the last two digits of an already used 8 digit module, you can plug in additional lines to my function"show_UhfFrequency()".

See below code snippets for markings "edited code for a F-16 UHF CHAN Display" to see where the changes have to be in the sketch. Beware of, that I neither touched the rest of for the A-10C UHF code nor tested the edited sketch with hardware.

Note, that an additional variable "String uhfChan" is created in the head of the sketch to convert the output String of the Channel to an integer and use the "showNumber" feature of the TM1637 library in the end.

Thank you Vinc, very much appreciated!  I have the Channel on a separate display but this should get me started to where I need.

 

Cheers

@Vinc_Vega  Well I'm beat, I thought I could edit it to work on a second display but I can't.

[Vinc_Vega]

@Hammer3246

Have you already tried to declare two display objects?

#include <TM1637TinyDisplay6.h>
TM1637TinyDisplay6 display(4, 5);// Create a display object -> display for frequency
TM1637TinyDisplay6 display2(11, 12);// Create a second display object -> display2 for channel

Talk to both displays like so

display.clear();
display2.clear();

The last lines of above code than must be changed in somethin like that

// ---- edited code for a F-16 UHF CHAN Display
  display2.showNumber(digit7, false, 1, 0);
  display2.showNumber(digit8, false, 1, 1);
// ---- end of edit

@Vinc_VegaThanks, I did declare the two displays,  and added some other lines similar to those.  I get a not declared error when I try to compile it (don't recall which exactly).  I'm gone to work for a couple weeks. So I'll try again when I get home.

 

Thanks
