Can anybody help me?

What does 0x00, 0x91, 0x02 and so on mean?

I don't understand what it says, and therefor have problems programming...

probably a stupid question, but I'm just a newbie

First, these are Hexadecimal numbers or, base 16, rather then base 10. Think of it as having 8 digits on each hand, instead of 5.

```Decimal     Hexadecimal        Binary
0     =     0x00     =     0000-0000
1     =     0x01     =     0000-0001
2     =     0x02     =     0000-0010
3     =     0x03     =     0000-0011
4     =     0x04     =     0000-0100
5     =     0x05     =     0000-0101
6     =     0x06     =     0000-0110
7     =     0x07     =     0000-0111
8     =     0x08     =     0000-1000
9     =     0x09     =     0000-1001
10     =     0x0A     =     0000-1010
11     =     0x0B     =     0000-1011
12     =     0x0C     =     0000-1100
13     =     0x0D     =     0000-1101
14     =     0x0E     =     0000-1110
15     =     0x0F     =     0000-1111
```

Second, for the amount of information you've provided, these numbers can mean anything! It is all in the application and what you or the controller thinks they should represent.

So, this question has "Insufficient Data " to provide any reasonable answers, more than what I have provided.

But even still, the answer provided is better then "That does not compute! "

You can avoid reality, for a while.  But you can't avoid the consequences of reality! - C.W. Livingston

The first n is not variant. The prefix is always "0x".

The same as \$00, \$91, \$02 or 00H, 91H, 02H..... now if we don't understand the difference between hexadecimal, binary, octal or decimal we have a problem...:?
