Hi i am looking for a little help, Ihave inherited a model 3b running some code written years ago, I need to get the code to run on a newer Pi
due to the discontinuation of the model 3.
when i move the sd card to a 3B+ i get 4 long flashes and 7 short from the green led, I have tried with a new image and the 3b+ works fine.
can anyone give me any advise as how to port over to the new boards without re writing the whole thing ?
i have searched and tried everything i can find but always ends up with the same problem.
