CCS V.4.107 PIC16F1826 Undefined identifier -- setup_ccpx I need use PWM. how to setup PWM
Code:
include <16F1826.H>
#fuses  INTRC_IO,NOLVP,NOWDT,NOPROTECT,MCLR
#use delay(clock=32M)

#byte CCPR3L = 0x311
#byte CCPR4L = 0x318
#byte CCP3CON = 0x313
#byte CCP4CON = 0x31A

int8 i;
int16 cnt;               
#define delay_ms(x)            \
cnt = x;                       \
   while(cnt)                  \
       {                       \
       for(i=0; i<8; i++)      \
          {                    \
           delay_cycles(250);  \
           delay_cycles(250);  \
           delay_cycles(250);  \
           delay_cycles(250);  \
          }                    \
       cnt--;                  \
      }                   

//========================================

void main()
{
   
   setup_ccp3(CCP_PWM);               //compiler Undefined identifier
   setup_ccp4(CCP_PWM);               //compiler Undefined identifier
   setup_timer_2(T2_DIV_BY_16,255,1);

Look at the data sheet.
Table 24-1
What does it say about CCP3, and CCP4?.
