Help to fix this Error "undefined identifier" |

Hello everybody, I want you to help me to fix this problem. I made a program but I don't understand why pic c don't identify these three instructions:
* setup_power_pwm_pins(PWM_COMPLEMENTARY, PWM_COMPLEMENTARY, PWM_OFF, PWM_OFF);
* set_power_pwm0_duty();
* setup_power_pwm(PWM_FREE_RUN|PWM_DEAD_CLOCK_DIV_2, 1, 0, POWER_PWM_PERIOD, 0, 1,4);
Are there related to some library.....? give me a solution please. |

Which PIC are you trying to use?
Which version of the compiler ??
Do BOTH the PIC and compiler have those functions ?? |

Since you don't provide a lot of helpful information, we are shooting in the dark, but did you include the correct header file for your processor of choice? _________________ mikey

Post a SHORT, but complete, compilable code which shows the problem.
In other words, reduce your code to as FEW lines as possible, but still giving the errors. We don't want to wade through mountains of code.
Probability is someone here will help you.
Include your PIC and version No.

Hello, I am using pic 16f877a
and for the compiler I am using pic c 4.084.
I don't know for the pic but I am sure that these instructions are functional in the compiler. I find them in the manual of pic c |

Do a Google search for the following string, and you will see some PICs
that have the Power Control PWM module:

site:microchip.com "power control pwm" type:pdf |
The 16F877A does not have it. |

I don't believe Power PWM is available on PIC16F chips.
Whoops, a little later than PCM on this one... _________________ Google and Forum Search are some of your best tools!!!! |
