Hi,i've read the Microchip appliction notes for sine wave with the 16F series chip..http://ww1.microchip.com/downloads/en/AppNotes/00655a.pdf together with the examples given in http://www.picbasic.co.uk/forum/content.php?r=229-Sine-wave-using-DT- interrupts and http://www.picbasic.co.uk/forum/showthread.php?t=14359.

there are number of things which i've not understand from these readings and i'm asking for help from anyone who can help me to understand.these things are:
1)how to generate a lookup table for the sine waveforms
2)how to include DT_INTS-18.bas file so that when i compile,the compiler will be able to open it
3)what is the purpose of this piece of code from example of http://www.picbasic.co.uk/forum/cont...-DT-interrupts

asm
__CONFIG _CONFIG1H, _OSC_HSPLL_1H
__CONFIG _CONFIG2H, _WDTEN_OFF_2H & _WDPS_512_2H
__CONFIG _CONFIG4L, _LVP_OFF_4L
endasm

thank you in advance.
