const table |

Hi
I use a 16F76 and the CCS's version 3.185
I have defined a const table like this:
const char cName[40][3][17] =
{
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
...
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"}
}
When I compile I have "Subscript out of range"
I try
const char cName[5][3][17] =
{
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"},
...
{"Xxxxxxxxxxxxxxxx","Yyyyyyyyyyyyyyyy","Zzzzzzzzzzzzzzzz"}
}
It's work
The difference I see is that the table is 255 octets in the second test.
I try #device *=16 and have the same problem.
Someone can help me? |

I don't think that CCS permits a const array to be larger than
a ROM page, which in your case is 2048 bytes.
Each of your strings is 17 chars long. Plus, each one has a 0
on the end, to make it a string. Also, the compiler adds at least
4 instructions to the beginning of each string, to allow it to get
chars from the string. So that's 21 ROM words per string.
That gives 40 x 3 x 21 = 2520 which is greater than 2048. |
