PIC ile sinüs ve üçgen dalga üretimi

[tuzluerik]

Merhaba arkadaşlar ben pıc ile üçgen ve sinüs dalga üretmek istiyorum. sinüs dalgayı ürettim ama üçgen dalgayı üretemiyorum yardımcı olabilir misiniz?
sinus1 deki değerleri üçgene göre ayarlıyorum ama üçgen dalga üretemiyorum sorun nerde acaba?
sinüs dalga kodu :

#include <16F877A.h>
#FUSES NOWDT,XT,NOPUT,NOPROTECT
#use delay(clock=4000000)
#use fast_io(B)
#define pwm PIN_B0

Tabloda üçgene göre ayarladığın değerleri paylaşırmısın.
