Writting Compact Tables

[Suraj143]

Can somebody tell me a way to write a table in a more compact way.

I use the below method it uses lots of lines in the code.I need C style written tables.I use assembly.

Table	addwf	PCL,F
	retlw	b'00000000'
	retlw	b'00000001'
	retlw	b'00000010'
	retlw	b'00000100'
	retlw	b'00001000'

Which Chip? The 16F ones with writable flash can hold two 7 bit values per location and 18F can hold two 8 bit values per location.

Hi Mike I'm using 16F series.I use PIC16F628A.

The 16F628A doesn't have writable flash. If you switch to the 16F88 then you will be able to write compact tables. It also has twice as much memory so you could hold 4 times more messages.

Edit, if it's just the number of lines your woried about then you can do,

    dt    b'00000000',b'00000001',b'00000010',b'00000100',b'00001000'
    dt    "Hello World!",0
