Cordic trig assembly code for PIC18f

Uh-oh.. just including the line:
include "trig-pic16.inc"
causes this:

I'm using a 16F877 too.

Use MPASM for the assembler.

Thanks Darrel,
I'm working on hardware now, but I'll try again as soon as possible.
Any idea on my first question?

It seems that this line becomes offensive:

Code:

'@ DEVICE LVP_OFF,BOD_OFF,HS_OSC				'

Which is how I set configuration.

You need to use a different syntax for MPASM.

like this:

Code:

Example: To set the PIC for Internal Oscillator allowing use of the OSC pins as I/O...

@ __config _INTRC_OSC_NOCLKOUT

Only one config statement is allowed when using MPASM, so multiple definitions follow-on from each other each connected to it’s previous buddy with an &.

Example: Typical Settings for a 16F628…

@ __config _INTRC_OSC_NOCLKOUT & _WDT_ON & _PWRTE_ON & _MCLRE_OFF & _BODEN_ON & _LVP_OFF & _CP_ALL & _DATA_CP_ON
