.56" 7-Segment and Backpack Decimal Points and Individual Se

Post by JonathanTeixeira »

Hello.

Quite new to all this.


How do I have just the decimal point of a particular digit point turn on?

Also, how would I have just the bottom segment of a specified digit turn on?

Additionally, is there a map or something for figuring out how to address particular segments / groups of segments?

Thanks a ton!

You can use writeDigitRaw library function to control segments individually

The segment mapping is as follows:
