I tried to search the forum and find the answer - maybe it is already here and I missed it. I have an all in one clock that I substituted the IN-14 tubes for IN 8-2 tubes. I edited the "byte decodeDigit" section of code to match my tubes but now I can not seem to upload it back to the arduino chip. I get the following error:
ardunixFade9_6_digit_edit:31:10: error: DS3231.h: No such file or directory
The gist of that pile of messages from the compiler is that your Arduino IDE doesn't have the right DS3231 library installed, or it's installed and somehow got broken. Get the library and (re?)install it using the normal Arduino IDE method of manually installing libraries.
The "10" are just place holders from what I understand. I have literally just changing all the digits (except the 10s) to the same number and seeing what lights. This is how I figured I am using the #1 as the anode - because I don't get that number in any of my tubes and some values do not light any numbers.
Alright so I am now going with IN-16 tubes 1) because it is what I have on hand 2) the IN-14 are more than i want to pay for at this time (i should have researched this more before jumping in) 3) The IN8-2 tubes i bought were all half dead.
So what i have been able to figure out by process of elimination is that pin positions 2 and 13 are not addressed for IN-14 tubes - but these positions on the board are where digits 0 and 1 have pins on the IN-16 tubes. Seems that these cannot be addressed in the code? I am going to do some deeper reading of the code but any help would be welcomed.
