So it is a constant current LED driver which requires a PWM input in order to set the current flow through its output. A PWM signal doesn't have "bittiness". Show 8 more comments.

The text between the lines is what is causing the confusion.

You are making this very difficult. The datasheet is 19 pages long. Where in the datasheet is this stated. Show 1 more comment. Scott Seidman Scott Seidman Add a comment. Sign up or log in Sign up using Google.

Individual digits may be addressed and updated without rewriting the entire display. The MAX also allow the user to select code-B decoding or no-decode for each digit.

This is a 5V operation device. If you need to run it by the book at 3. For more details please see MAX Datasheet. For a true native 3V operation or segment blinking, i will recommend you to look at the MAX datasheet. For testing, just save the code on ESP as ' max If you want your MAX Display Driver to start automatically when your ESP module starts or reboots, then you neet to create and add some lines in your ' init. Save the code on ESP as ' init. It should reboot and restart automatically the program.

For my project I will only need 5 out of 8 digits to display possible values, but these values can also be negative. Good stuff, thanks!
