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.
