- Yes, I agree 0 is not correct. On this page it says: "The fourth argument to LedControl(dataPin,clockPin,csPin,numDevices) is the number of cascaded MAX72XX devices ... only values between 1..8 are allowed here.". Please add a link to the source of your code. Perhaps there is an explanation there why 0 was chosen.st2000– st20002024-02-05 13:16:54 +00:00Commented Feb 5, 2024 at 13:16

How to Format

def function(foo):
print(foo)
``` - put returns between paragraphs
- for linebreak add 2 spaces at end
- _italic_ or **bold**
- indent code by 4 spaces
- backtick escapes
`like _so_` - quote by placing > at start of line

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. arduino-uno), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
