What's the correct way to specify a number in binary format in C ? |

Thanks for pointing it out. I had a look at the reference Manual (around page 40), but I still don't know it. Do I need to use const? Sorry for that, but I have no idea. Please tell me....  |

No, you don't need to use 'const'. Without it, the array will be placed in
RAM, which is perfectly OK.
It just occurred to me that you mean you don't how to specify binary
format. Just put '0b' in front of each of the numbers in your array.
(Without the single quotes). |

d'jou look at your LST file to see what this signed int8 compiles to??
| Code: |
int8 j[8] = {10001000,01110001,01010001,01100001,01111001,01110101,01110011,01110000};
|
IMHO - VERY odd notation you use there - so
after you read the .LST -- -is it REALLY what you were after??? [/b] |

It is all shown in the CCS manual. It gives the prefix to use:

Constants:
123 Decimal
0123 Octal
0x123 Hex
0b010010 Binary

Enough on bonehead programming. We don't need a huge thread on
basic bonehead stuff. |
