Thanks for your answers, Mike. But that is not what I need, I think I have expressed myself the same, probably because of the language, since I am Spanish and my English is not very good. What I need is to be able to connect another 7-segment LED display, the same as the one on the board but a little bigger. So I don’t know if I have to modify the Software. I put here a picture of the screen that I would like to put, if possible please.
