Arduino/7-Segment Question

[JG14_Smil]

Hello,

 

I came across this a while ago and thought it would be good for the RSBN control panel in my pit.

 

https://www.allelectronics.com/item/sda-20/4-digit-7-segment-serial-display/1.html

 

I was worried as they showed no documentation, but a search found excellent documentation here:

 

https://learn.sparkfun.com/tutorials/using-the-serial-7-segment-display/introduction?_ga=2.256199243.1780542026.1558745994-1561300509.1558745994

 

I tried a UART serial connection and to my surprise, got it working with the supplied code.

 

I have a neighbor that can help me with any difficult code, but I am trying to learn what I can before then. My question is: Will I be able to define (two) two digit displays for my RSBN Nav and Landing channels?

 

Here is a photo of the panel. Please forgive the terrible picture...

 

 

Not sure of how to do code snippets.... will be back if I get it.

I noted this code:

 

sprintf(tempString, "%4d", counter);

 

// This will output the tempString to the S7S

s7s.print(tempString);

 

I am guessing the two 2-digit strings would be defined in this section...

 

 

Thanks for any advice... just trying to learn at this time.
