Data tables in ROM

[Drenov]

Hello All,

I am looking to store an 8 bit look up table in an 18F4410. I would like to use the table read instructions. I am using MPLAB and I don't know how to put the data into the code space.

I have tried :

org 0x0100
LUT:
data 0x00, 0x01, 0x02, 0x03, 0x04, 0x05, 0x06, 0x07

When that compiles the listing shows that it's been converted to a NOP

I can use :
addwf PCL,f
retlw 0x00
retlw 0x01
retlw 0x02....

But that takes 2 bytes to store each byte, and a few clocks wasted jumping about.

What is the best way to do this ? Any ideas / constructive advice always welcomed

Regards

Dren

Maybe you did not notice but this forum mainly deals with Pic Basic Pro.
Are you using PBP? If not you may want to try here

Or are you trying to save a bit by using ASM?

I found I could get around it by using :

data 0x0000
data 0x0001...
