Hi,
First, learn to use the 'Code' buttons when posting your code. This will preserve the formatting, and make the code much easier to read.
The next thing I would do is to figure out a 'protoco ... |

Hi,
I think I'm going to give up on this thread. The first time I asked what was the voltage being applied to AN0, you said '5V', and it was supplied by an LM35. I pointed out that this was most li ... |

Hi,
You've got to learn to troubleshoot. I've been helping you along the way with the hopes that you would do more and I would do less. So far that isn't happening. I understand the language issues ... |

Hi,
Setting aside the timer issue for the moment, is the A/D actually working as expected? What numeric value is being returned? How are you converting the numeric A/D value to temperature? Are you ... |

Why set the timer?.
On the PIC30's, you can program the reset point for each timer. Setting the timer to a value is pointless on these chips. He is doing this for Timer2, but not for Timer1....

Hi,
...........the voltage is 5V on this pin........."LM35" is connected to AN0....
Now, that doesn't seem correct, does it??? You have some sort of a wiring or hardware problem! The ... |

Hi,
You need to add another boolean variable, and move the A/D read and math out of the interrupt.
int1 Read_Analog_Ready = False; //This is a global variable
if(dem==time_lay_mau) ... |

Hi,
Here is what I mean about 'Errors':

Regarding the 'flag' to signal Main() that a new duty cycle has been re ... |

Hi,
You ignored my advice from your other thread (on the same project) to add 'Errors' to your #use_rs232 directive, and you've ignored Ttelmah's advice to set a flag in your ISR when duty changes, ... |
