thanks man, i have a problem with this library i cant write the decimal point with a number

[@robojax]

of course you can't . this is just for integer display. it would have shown if it worked. not worth spending time on this.

[@contrarian8870]

Do 7-seg displays like this need a constant refresh? I.e. do we need to write the signal CONSTANTLY in a loop, or is it sufficient to write once, and then do nothing (e.g. for a few secs) until a change is required?

[@dani777dani]

is 7219 or 7291? "Lesson 23: MAX7291 4 Digit Display | Arduino Step By Step Course"

[@robojax]

the title written is correct. See manufacturer website www.maximintegrated.com/en/products/power/display-power-control/MAX7219.html
