rom TABLE

[Guest]

Hi,

I'm a newbie in C and I want to know how I can implement a table in rom;
for example if I have this in assembler, how i can 'translate it in c?

#org 1000h
DB 01,02,03,04,05,06,07,08
.
.
.
#org 2000h
DA "HELLO WORD! "
.
.
.
#END

Thanks to everybody

It's done with a #rom statement.

#include <18F452.H>
#fuses XT, PUT, BROWNOUT, NOWDT, NOLVP
#use delay(clock=4000000)
//#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7, ERRORS)

#rom 0x1000 = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08}
#rom 0x2000 = {"HELLO WORLD! "}

// Notice this 2nd method. It uses 'int8' and will pack two bytes
// per ROM word, instead of one byte per word. Look at the Program
// Memory window to see this.
#rom int8 0x1100 = {0x01,0x02,0x03,0x04,0x05,0x06,0x07,0x08}


//==================================
void main()
{



while(1);
}

Thanks a lot !!

I have an other question:
If I want to read this data from ROM and put it to a RAM buffer -in assembler I can use 'table read' or 'table write' instruction- , which is the C sintax? The sintax is the same for data (0x01,0x02 ....) and ascii ("HELLO ...")?
Thanks in advance and sorry for my bad english!

Ok,
now I understand better (I hope ) how C works and I can try to realize my application (but I hope to find you another time if I have others problems... ops!).
Thank you to everybody for help.
