Displaying value on 2 line 4 digit 7 segment code
I have using arduino Uno . I have used serial in parallel out to display the parameter. Here i am pasting the piece of code.
Totally i have 8 digit of 7 segment display.Dissect & Dissect2 split the value and place into segment
Currently i have test condition under current fault.
with below piece of function I could able to display 001.3 on top and UC-F at bottom.
I am looking for C function where i could able to display like
R01.3 on top and UC-F on bottom.someone help me coding to display character like mentioned.
