LPC1758 with LPCXPresso
How can I define a string + number like this:

const char Driver [18]= "ABCDEFGHILMN",{18,03,20,11,15,55};

Thanks

Each character in a string is an ASCII code representing the number. For the letters, only one byte is needed. For the numbers, each digit needs its own byte. 18 is not going to be enough. What exactly are you trying to do? If I know the end result, I will be able to help better.

I suspect that the compiler sees this as you trying to assign a two dimensional array (the string as one, the numbers as another) to your single dimensional Driver array.

Try this instead...

const char Driver [19]= {'A','B','C','D','E','F','G','H','I','L','M','N',0,18,03,20,11,15,55};

Hello blasiis,

Do not forget the '0' between the [B]'N'[/B] and the [B]18[/B] ... and the increase of the amount of array cells from 18 to 19.

Trying with 19
const char Driver [19]= = "ABCDEFGHILMN",{18,03,20,11,15,55};
I have the error expected identifier or '(' before '{' token
I think itisn't possible !

It's possible, and already posted by CodeRedSupport :mad:

const char Driver []= {'A','B','C','E','F','G','H','I','L','M','N',18,03,20,11,15,55};

Watch Expression shows:

"ABCEFGHILMN\022\003\024\v\017\067"

That's your string and your numbers (octal) :)

Why it is in octal format ??
Can I use a hex format ?

Don't know why strings in 'Expressions' are displayed octal, if they are not displayable as character set.

At the left side you can display your array in hex format, see:
