| pwm for PIC16F1507...PIC16F1507 |
 Posted: Sun May 06, 2012 5:10 pm |

I tried to create pwm (for PIC16F1507...PIC16F1507 ) and I saw that for these micro-controllers the instruction:
| Code: |
setup_ccp1(CCP_PWM);
setup_ccp2(CCP_PWM);
|
is not working. (For other micro-controller this instruction is working). The datasheet for these micro-controller describe that are provided with pwm.
What is going wrong?????? |

What version of CCS are you using? What "other microcontroller"?

post your CODE that tries to use PWM - all of it
post your compiler version
post your SCHEMATIC that shows how you plan to use the PWM |

I am at the process to find the pic so my code is just few instructions to check the pic :
| Code: |
#if defined(__PCM__)
#include <16F1507.h>
//#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#elif defined(__PCH__)
//#include <18F2423.h>
#fuses HS,NOWDT,NOPROTECT,NOLVP
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#elif defined(__PCD__)
//#include<30F2010.h>
#fuses HS,NOWDT,NOPROTECT
#use delay(clock=20000000)
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
#endif
void main()
{
setup_ccp1(CCP_PWM);
setup_ccp2(CCP_PWM);
} |

If you believe the compiler has a bug, then always post your compiler
version. A request that you do this is in a "sticky" post by Temtronic
at the top of the forum. Please read this. |

| Code: |
{
setup_ccp1(CCP_PWM);
setup_ccp2(CCP_PWM);
|
This is an inadequate amount of setup code.
You have not setup a timer to drive pwm or
set a PWM duty cycle VALUE to generate yet.
Your code is very very incomplete.
Do as PCM says
post your compiler version while you are at it. |

What you really mean is that those lines of code give a compiler error.
They don't compile. You get these errors:
| Code: | *** Error 12 "16F1507.c" Line 8(11,12): Undefined identifier -- setup_ccp1
*** Error 12 "16F1507.c" Line 12(14,15): Undefined identifier -- set_pwm1_duty
|
I tested this just now with vs. 4.132, and it doesn't have any support for
the PWM module in the 16F1507. The 16F1507.h file doesn't have any
constants for PWM functions.
It's possible to add support by writing your own PWM functions, similar
to the CCS functions. Or, you can write directly to the PWM registers
in your program. |
